▼ Though
drought is a recurrent natural disaster in Texas, little attention has been so far paid to the preparedness of
drought for spatial
drought risk assessment. This study presents a methodology for spatial assessment of
drought hazard, vulnerability, and risk in the Edwards Aquifer (EA) region. A conceptual data-based framework for
drought hazard and vulnerability was developed in this study. Standardized Precipitation Index (SPI) and Effective
Drought Index (EDI) methods were used to identify
Drought Hazard Index (DHI) in different time steps, while the GIS environment was used to map the spatial extents of
drought hazards.
Drought Vulnerability Index (DVI) was identified by using different social and physical consequences of
drought and a thematic map was prepared on the county level for vulnerability assessment. The risk, as a result, was computed as the product of intersection between both the DHI and DVI. Very high
drought risk was found by 9 and 24-month SPI and EDI in Bexar (9.8% of the area). The highest percentage of the area in high level
drought risk was detected by 1 and 12-month SPI as 32.3% of the area and 3-mont SPI found the highest moderate percentage of the area (79.5%). Bexar was found under
drought risk based on all time scale SPI and EDI (very high
drought risk based on 9, 24-month SPIs and EDI). Medina, furthermore, was detected in high
drought risk in terms of all time scale SPI (except 3-month SPI) and EDI. In general,
drought risk is higher in counties of the southern part of the area. The results confirmed that higher
drought risks are found where both high hazard and high vulnerability coincide.

Evaluating the effect of climate change on groundwater

▼ There is strong evidence that climate is changing and
will affect the water resources. A major question arising from the
evaluation of climate change (CC) impacts on groundwater resources
is to what extent groundwater recharge will change. Given that for
Switzerland, climate models predict more frequent hot and dry
summers in the future while precipitation will tend to increase in
winter, a special attention was given to possible changes in the
seasonal distribution of recharge. However, to provide robust
predictions, uncertainty has to be considered in all simulations.
Three uncertainty sources can be distinguished: the latter can
originate from climate models uncertainty, the unknown evolution of
land use and society in general, and the hydrological models
themselves. The role of these three types of uncertainty has
received a major attention in this study. Three studies were
carried out to evaluate the effect of CC on the hydrological
system. Two of these studies were dedicated to the topic of
groundwater recharge whereas the third was focused on the CC
response of an aquifer system. The first recharge
related study deals with the question of how uncertainty due to
climate models interacts with uncertainty associated with different
hydrological models. Although different models were used to
simulate groundwater recharge in numerous climate impact studies,
it is not yet clear whether models of different complexity give
similar recharge predictions for a given climate scenario.
Therefore, five different commonly used approaches to simulate
groundwater recharge were compared under CC. In this
analysis models with different complexity were applied over a time
span of several years and predictive model bias occurs. Using CC
data with more extreme weather conditions increases the resulting
bias. The potential for model predictive error increases with the
difference between the climatic forcing function used in the CC
predictions and the climatic forcing function used in calibration
period. The difference between the reference recharge and simulated
recharge from physical based but homogenous model as well as
semi-mechanistic model are smallest whereas the differences
increase with the simple models. The differences are due to
structural model deficits such as the limitation of reproducing
preferential flow. Thus, results of CC impact studies using the
soil water balance approach to estimate recharge need to be
interpreted with caution, although the majority of CC impact
assessment studies are using this approach. Comparison of both
uncertainties, i.e. CC and model simplification, indicate that the
highest uncertainty is related to CC, but a model simplification
can also introduce a significant predictive error. The
second recharge related study explores how different crops and crop
rotations influence CC effects on groundwater recharge. The
predicted temperature increase will doubtlessly lead to an increase
in evaporation and can be intensified by the presence of crops. To
address this question, we relied…

▼ This research looks at the past century of Texas and New Mexico climate in order
to create datasets sufficient for documenting climatic variations. Inhomogeneities in
climate records are defined as variations in climatic records caused by factors other than
weather and climate. While there are indirect methodologies for inferring climate records
such as tree rings and ice cores, it is the instrumental network that constitutes the most
spatially and temporally complete record of land surface climate since the onset of the
Industrial Revolution. A statistical method by Sun and Peterson (2005a) called Inverse
Weighting of Square Distance (IWSD) will be used to reduce the inhomogeneities in
climate records.
The National Weather Service Cooperative Observer Program (COOP) network
of stations will be used for this analysis. A subset of the extensive COOP network, called
the United States Historical Climate Network (USHCN), will be used as a foundation for
this study. The analysis and resulting datasets from this climatic study show precipitation
trends and periods of
drought and will be useful for decisions regarding future policies on
drought. The result of the interpolation process was the creation of several COOP and
USHCN datasets. Several of the datasets were investigated to determine the spatial
characteristics of precipitation over the 20th century in Texas and New Mexico. The
datasets are in good agreement that the most severe
drought period of the 20th century in
Texas and New Mexico was in the 1950s. The frequency of pluvial periods was higher
toward the end of the 20th century, with most USHCN stations showing an increasing
trend when a linear regression analysis was done on each station's precipitation data.

▼ The ever-growing world population raises the concern and necessity of rational use and distribution of limited water resources. Water deficit is the single most dominant abiotic factor limiting cotton (Gossypium hirsutum L.) yield in
drought-prone Texas croplands. Characterizing plant traits conferring
drought tolerance to cotton genotypes and then transferring this information back to breeders and geneticists have the potential of significantly increasing and stabilizing production statewide. Although a plethora of physiological studies have been conducted and have demonstrated that
drought tolerance in plants is likely to be conferred by a combination of plant traits rather than a single trait, this knowledge has not translated into improved breeding lines. Experiments were conducted in 2010 and 2011 in the
Drought Tolerance Laboratory (Texas AgriLife Research and Extension Center in Corpus Christi, TX) to analyze the responses of cotton genotypes to different levels of water stress. This facility is equipped with computerized systems capable of continuously monitoring whole-plant water use as well as several environmental parameters. Sixteen cotton genotypes were provided by Monsanto Co. and the Texas AgriLife Cotton Improvement Programs at College Station and Lubbock. Seeds were pre-germinated in wet paper towels and then hand planted in large pots previously filled with fritted clay. A total of 3 and 8 (2010 and 2011, respectively) pots containing plants of each genotype were permanently placed on micro-lysimeters for continuous measurement of water use. Water regimes were imposed in 2010 (well-watered and water-stressed), and 2011 (water-stressed) when plants reached the early-flowering stage and were carried until plants reached maturity (100% open bolls).
Data collected showed that genotypes have very distinct water use patterns. The water stress treatment imposed on the test plants negatively affected plant growth that was indicated by a lower plant height, total number of leaves, and main-stem nodes of stressed plants when contrasted to their well-watered counterparts. Stomatal density was remarkably different among genotypes and a higher density was found on the abaxial (lower) leaf surface for all genotypes studied. Root dry mass production had different responses depending upon the severity of the water stress. Highest root dry mass was observed when plants were exposed to a mild stress and lowest when a more severe water restriction was imposed.

▼ Severe droughts have plagued the United States over the last few years. The 2011 Texas
drought, the 2012 U.S.
drought, and the current California
drought have greatly impacted the nation’s economy and agricultural production. Different crops vary in their response to water stress. Despite this, commonly used
drought indices, such as the Palmer
Drought Severity Index, do not consider crop specific factors. The goal of this project was to create a methodology to produce crop and location specific
drought and yield trend forecasts to help agricultural producers make more informed water management decisions. To achieve this, a
drought index was developed and analyzed, weather forecasts were used in a hydrology/crop model to predict hydrologic conditions and crop yields, and an example interactive map interface were created to convey this information to water stakeholders.
The
drought index uses five parameters that affect or are affected by
drought. These parameters include precipitation, temperature, cumulative biomass, soil moisture, and transpiration. Soil moisture and temperature are ranked against crop-specific threshold values, while precipitation and cumulative biomass are ranked against location-specific normal values. Transpiration is ranked against the location-specific potential transpiration. A case study was performed in the Upper Colorado River Basin located in West Texas using this
drought index. Cotton is the primary crop grown in the watershed and was used in this study. The Soil and Water Assessment Tool (SWAT) was used to estimate the cumulative biomass, soil moisture, and transpiration. A multiple linear regression model was developed for each week of the growing season based on the significant parameters during that stage of the growing season. These models were used to predict yield trends and
drought severity.
Two week forecasts for each
drought parameter, yield trends, and the
drought index were generated for 2010 through 2013 by using forecasted precipitation and temperature data as inputs for the hydrologic and crop model. This provided forecasted soil moisture, transpiration, and cumulative biomass production. Parameter rankings, yield trends, and the
drought index were compared for those calculated with actual precipitation and temperature data as well as forecasted precipitation and temperature data. The precipitation ranking, temperature ranking, cumulative biomass ranking, transpiration ranking, estimated yield trends, and
drought index indicated satisfactory forecast results. The soil moisture forecast did not result in satisfactory forecast.
The final step in the project was to create an example interface for agricultural producers and water managers to view
drought related stresses. ArcGIS online was used to create maps which show graphs of the weekly
drought index and soil moisture ranking. Maps were created at the county scale. These maps provide agricultural producers readily accessible information that can be used for decision making related to water management.

▼ The problem of drought and erratic rainfall, coupled with crop genotypes (both local and improved varieties) with low water utilisation efficiencies, are major contributors to low productivity of most crops. The poor agricultural productivity among the farming community results in poverty and food insecurity at national level and in low household incomes.
Selection of drought adapted genotypes in breeding programmes and efficient use of water are among the most important approaches in combating climate change effects like droughts and erratic rainfall. This study was conducted to characterise drought tolerance of twelve maize genotypes. An experiment was set up at the National Irrigation Research Station in Mazabuka, to determine the response of these genotypes to three water regimes at 30 %, 60 % and 100 % of crop water requirement (ETc). The twelve maize genotypes were planted at each water regime in a split – plot design arranged in a randomized layout. To evaluate the water utilisation of each maize genotype, water use efficiency, crop water productivity, crop yield response factor and harvest index were determined from the grain yield, above ground biomass and data collected during the experiment.
Deficit irrigation (30 % and 60 % ETc) resulted in crop yield reduction and significant effects on most of the measured parameters. Anthesis – silking interval was shortened, plant girth and height equally decreased with increased water stress at 30 % of ETc. The results showed variations in maize yield and this was attributed to genotype and water regime. The genotypes and water regimes contributed to yield by 30 % and 50.2 %, respectively. The grain yield in genotypes L512, L353, L857 and L07 had a yield advantage of 36.8 %, 34.6 %, 27.6 % and 18.0 %, respectively above the overall mean. Water Use Efficiency (WUE) at 30 % water regime was high in maize genotypes L512, L60, L713 and L857 with 2.412, 1.818, 1.900 and 2.265 kg/mm/ha, respectively. The Crop Yield Response Factor of genotypes L353, L512, L07 and L857 at 60 % water regime were below 1.0 indicating an efficient water use by most genotypes at 60 % water regime which resulted in a seasonal accumulative value of 505.3 mm for the season under study.
Based on the results, genotypes L512, L857, L07 and L353, were selected as drought tolerant genotypes.

▼ The boreal forest of Canada extends across 58% of Canada’s land area providing a large range of ecosystem services including flood control, water filtration, and carbon storage. Despite conservation efforts to protect this ecosystem, the boreal region is still under stress from global stressors including climate change. Anthropogenic climate-change is expected to raise temperatures and decrease precipitation over much of the boreal region increasing the duration and magnitude of droughts. This potential change to a more arid climate could have drastic affects on water levels and stream flows across much of the boreal region. Changes in hydrology, as a consequence of anthropogenic climate change, may result in large changes to aquatic ecosystems. To assess the susceptibility of lakes to climate in northwestern Ontario over the past two millennia, sediment cores from a headwater lake were obtained from near-shore cores to reconstruct changes in drought.
The cores were located at a depth where changes in pelagic and benthic diatom assemblages (P: B boundary) were apparent in modern-day sediments because the location has been shown to be susceptible to change. The lake chosen for reconstruction was Gall Lake, a small (surface area = 9 ha, max depth = 18 m, mean depth = 8.5 m), mesotrophic lake (total phosphorus (TP) level of 12.3 μg/L, July 2008), with a gentlysloping eastern basin. This headwater lake in the Winnipeg River Drainage Basin (WRDB) is part of a hydrologically-rich region that is expected to experience increased aridity. Multivariate analysis of diatom assemblages over the past two millennia suggested that the instrumental record does not encompassed the natural variability of this system. The largest decreases in diatom-inferred (DI) depth were synonymous with iii the Medieval Climate Anomaly (MCA), a phenomenon not yet observed this far northeast in North America. The MCA has been proposed as a surrogate for climate change over the next century, therefore the prolonged aridity observed in Gall Lake could aid in the calibration of general circulation models currently used to forecast changes in climate, as well as a scenario that can be used to develop adaptation strategies to future environmental change.

▼ Achieving food security in the Kenyan ASALs during drought is a constant challenge that begs for action. Reactive crisis approach to drought-risk management have over time been ineffective and poorly coordinated leading vulnerability of households to food insecurity despite development and implementation of drought risk mitigation strategies under HFA 2005-2015. This study sought to establish how drought mitigation strategies influence household food security in Laikipia East sub-County, Laikipia County, Kenya. The specific objectives looked at how drought preparedness, drought response activities and drought reconstruction activities after drought influence household food security. The study used descriptive research design. The population targeted was agro-pastoral households in Laikipia East Sub-county. Five sub-areas were purposively selected for the study. A sample was selected by use of Krejcie and Morgan table for determining sample size and sample of 242 households was selected from a target population of 649 households. Data was collected by use of questionnaires administered in the field to randomly selected households and eight key informants making a total of 250 respondents. However received filled questionnaires from the households, 219 were considered complete and reflective of study objectives. Data was analyzed by use of Statistical Package for Social Scientists and Microsoft Excel and presented using tables and subsequently interpreted. The findings of the study were that drought mitigation strategies influenced household food security but they were poorly coordinated, late, and insufficient and also lacked sufficient funding. The study also found out that household participation was low in implementation. The study recommends more capacity building on drought mitigation strategies, timely planning for drought to ensure coordinated response to drought especially in human and livestock relief projects. Finally the study recommends involvement of technical field officials and local leaders as they are better placed to identify working strategies and rightful targeting.

▼ Luangwa District in Zambia’s Lusaka province lies within a marginal area that is prone to
both drought and floods in the rainy season (Luangwa District Council, 2007). Despite small
scale farmers of Luangwa District employing various drought coping strategies, drought and
floods continue to adversely affect them in terms of food security and the general livelihood
of the population (Kaminsa, 2008). Although environmental learning for coping with drought
among small scale farmers has not been studied or explored, some scholars have explained
the role that environmental learning plays in coping with environmental hazards (Goulder,
1999; Holdren, 1990). The aim of the study was to examine environmental learning of coping
with drought among small scale farmers of Zambia’s Luangwa District so as to determine its
approapriateness.
To achieve this aim, the study established drought coping strategies among small scale
farmers of Zambia’s Luangwa district. Having done this, an examination of environmental
learning related to such drought coping strategies was done.
The study was a critical realist case study within a setting of qualitative methodologies. A
semi structured interview guide was used on disaster management officers, agriculture
supervisor, town planner and extension officer, while a focus group discussion was conducted
among the small scale farmers. Observations of farming activities on small holdings were
also done.
The study established that small scale farmers of Luangwa District mainly employed
traditional drought coping strategies. Furthermore, the study findings revealed that
environmental learning among small scale farmers was on general farming practices and not
specifically on drought coping. Thus the study findings confirmed literature assertion that
there was superficial environmental learning among small scale farmers.
Finally, the study comes up with a proposed environmental learning programme for drought
coping which may potentially be useful in addressing drought coping challenges among the
small scale farmers of Luangwa District. Thus a major recommendation is for the Ministry of
Agriculture and other stakeholders to introduce environmental learning for drought coping
among small scale farmers.Further, the government of the republic of Zambia needs to
allocate more funds to extension service.

▼ Drought is the major abiotic factor limiting crop production worldwide. Sorghum is one
of the most
drought tolerant grain crops that have the ability of addressing food insecurity
in semi-arid areas. However, it is exposed recurrently to severe forms of
drought and,
therefore, requires improvement to cope with moisture stress. The present investigation
was undertaken to improve local sorghum varieties for
drought tolerance in Burkina
Faso. A participatory Rural Appraisal was conducted to identify farmers’ constraints and
to determine their preferred sorghum varieties. One hundred and ten accessions,
including improved and introduced materials, were assessed in full irrigated and terminal
drought conditions in an alpha lattice design to identify
drought tolerant and high yielding genotypes. A molecular characterization using 26 SSRs markers was conducted with the same accessions to determine the genetic diversity, genetic differentiation and the level of homozygosity of these accessions. Finally, marker-assisted backcrossing was carried out to introgress stay-green QTLs into four farmers’ preferred varieties. The major constraint limiting sorghum production in Burkina Faso was Striga, a parasiticweed.
Drought was the second most important factor reducing sorghum yield and the most important abiotic constraint. The study revealed that terminal moisture stress was the most frequent type of
drought but has less effect on yield than pre-flowering
drought. Forty seven per cent of farmers rely preferentially on their local landraces. A few preferred improved varieties derived from local landraces, over high yielding exotic (introduced) varieties. Among released varieties, farmers grew more Kapelga in all different climatic zones of the country. There was a strong correlation between grain filling rates, yield under stress, grain number, Stress Tolerance Index (STI) and Geometric Mean Productivity (GMP). This indicates that improvement can be achieved using accessions with high STI and GMP indices. Classification based on yield and its components, divided accessions into three main groups. Grinkan was the highest yielding and most
drought tolerant genotype in the study. A group of high yielding and
drought susceptible accessions were identified including local improved varieties and landraces that performed well under non-stressed conditions and were susceptible to terminal
drought. Low yielding and
drought tolerant accessions were also identified. Genotypes
with high STI indices could be used by farmers to ensure optimal production in
drought
prone areas and in breeding programs. There was low gene diversity of 0.34 compared to previous molecular studies in Burkina Faso. The Fixation index (Fst) value exhibited low genetic differentiation among populations and moderate genetic differentiation between local population and exotic materials. The local accessions have a high level of
homozygosity. Five stay-green QTLs (Stg1, Stg2, Stg3, Stg4 and StgB) were incorporated into four recurrent (Kapelga, Sariaso09,…

▼ Individuals’ aspirations are receiving more attention in development economics as their role in decision making, future expectations, and well-being are recognized. High aspirational targets set by ambitious individuals may contribute to economic improvements, while low aspirations targets may sustain conditions of poverty in a negative feedback loop. Despite the connections to productive behavior, factors that may contribute to or work against the formation of aspirations have seldom been identified outside of the experimental setting. Particularly, we seek to understand how droughts impact individual aspirations. This report also makes the important distinction between perceived, actual, and expected
drought shocks, and identifies the various influences on goal-setting. Using data on 748 Zambian households, we show that perceived
drought length increased aspirations. Perceiving an additional day of
drought was associated with an increase of 0.232 and 0.212 standard deviations for livestock and asset aspirations, respectively. When using Climate Hazards Group InfaRed Precipitations with Station (CHIRPS) data, we see no effect on aspirations, suggesting that past perceptions – rather than the shocks themselves, which dictate household ambitions. Finally, when using the individual’s expectations of future
drought exposure, aspirations are reduced. Households that expect more frequent droughts in the next decade reduced a partial aggregate of aspirations by 0.295 standard deviations. The different effects observed depend on the subjective or objective nature of our shocks, and the orientation towards the past or the future, highlighting the complexity of identifying factors that contribute to the formation or destruction of aspirations.

▼ Due to
drought stress, there is a significant amount of loss in corn yield
caused by weather changes such as rising temperatures and the decrease of rainfall. With
the help of new genetic tools, improvements in conventional crop yields have shown
some success over the past several decades. Researchers have found that the native corn
genes allow
drought tolerance by comparing populations and parent lines in the
drought
environment. A managed stress environment (MSE) plays an important role by providing
the researchers an ideal place to manage the heat stress and irrigation water amount. This,
in turn helps, to validate candidate regions and genes by conducting massively parallel
transcript profiling studies. This type of study was performed in the field of research of
drought tolerant corn and project management, which focused on data collection from the
field. This research took place in Woodland, California, with a climate known to be droughtstricken.
It was concluded that modern hybrid seeds have improved in root distribution
and functional stay-green, and that yield in
drought conditions has increased. The same
types of qualities are shown in Optimum Aquamax Hybrid seeds, which are one of the
hybrid seeds released by Pioneer Hi-Bred in 2011. This hybrid showed a five percent increase
in the average yield. As a result, crop yields were shown to increase with the use
of
drought tolerant hybrid seeds.
This Professional Science Masters (PSM) Internship was performed in the areas
of research of corn and trial management. The main focus of the PSM Intern was on
collecting and organizing the data from the fields and on gaining knowledge of how agricultural
research projects are conducted by industry.

▼ In 2018 The Netherlands experienced the most severe
drought since 1976. In response to this, the Minister of Infrastructure and Water Management established the 'Beleidstafel Droogte'. An external scientific committee took part in the Beleidstafel Droogte. One of their key recommendations was to introduce other
drought indicators since the currently used indicator (precipitation deficit) is not sufficient due to limitations. This research investigates what
drought indicators can be used in The Netherlands to support anticipative
drought management. For water managers, it is crucial to know when and where
drought occurs, and how severe this
drought is. To reveal the start, severity, and ending of a
drought,
drought indicators can be used. However, to define
drought, regional differences need to be incorporated. Therefore, this research used a case study area to find out what
drought indicators can be introduced. Within the boundaries of this area, three different analyses were conducted: 1) hydrological analysis, 2) stakeholder analysis and 3) policy analysis. According to the results, a set of potentially relevant and suitable
drought indicators was selected. These
drought indicators were tested with focus groups to determine whether they can be used to support anticipative
drought management. The area of water board Vallei & Veluwe was selected as the case study area. Concerning the hydrological analysis, multiple methods were applied to obtain a better understanding of the water system and essential hydrological processes. Because of the relative nature of
drought, several stakeholders that are directly affected by
drought were interviewed. Through semi-structured interviews, information concerning
drought was obtained about the stakes and information needs for different stakeholders. Since measures can be taken to anticipate
drought or to mitigate
drought problems, the policy on
drought was considered. In this way, the interrelation between policy on
drought and
drought indicators was taken into account. The results of the analyses mentioned above led to the following selection of
drought indicators: SPI-1 & SPI-3, soil moisture, stream discharge, groundwater levels/isohypse, NDVI and EVI. To test the selected indicators can support anticipative
drought management, two focus groups session were organised. For these focus groups, a dry year was reconstructed, which was explored by the participants. Based on the information that was presented to the participants, they were asked whether they would advise taking measures and what their level of alertness was. One group received information from the selected indicators, whereas the other group received information which is used nowadays for
drought monitoring. After evaluating and comparing the focus groups, conclusions were drawn. The participants that received information from the selected
drought indicators acted more pro-active, because: 1) measures were advised more rapidly, 2) more measures were advised, and maintained applicable for a more extended…

▼ Drought causes extensive damage and affects a significant number of people. To quantify the severity of
drought and to better monitor
drought,
drought indices are necessary. The Palmer
Drought Severity Index (PDSI) has its advantages of comprehensive and taking the characteristics of
drought into concern so that it was regarded as the milestone in the revolution of
drought indices (Heim, 2002). The PDSI has been widely used, tested, and modified since its development in 1965. However, a commonly documented limitation to this index is the lack of consideration for snow and the treatment of ground status. In this study, a simplified snow model is included in the self-calibrated PDSI model, which is run in a monthly time step over the continental United States (CONUS) for the past 32 years (1979 - 2010). In the modified PDSI model, the form of precipitation is based on an air temperature threshold and moisture has been withheld and redistributed into the system based on the accumulation and melt of snow. With the snow processes included, all the model variables (evapotranspiration, soil moisture recharge/loss, surface runoff) decreased in winter and increased in spring melt time and soil moisture remained the same in winter and got recharged in spring, the difference between the soil moisture in the original PDSI model without snow effect and the soil moisture in the PDSI model with snow effect is small. The climatically appropriate precipitation increased more than 200% in northern latitude and mountain
regions in spring melt seasons. The absolute value of moisture departure also decreased in winter and increased in summer, which means the inclusion of snow processes made the moisture departure increase during wet condition and decrease for dry condition (varies more). Inclusion of the snow model also allows the PDSI to better capture spring flooding events, which are caused by snowmelt; monitoring
drought events also has been improved due to the changes in duration factor for the modified model with snow processes. Finally, the general moisture conditions as well as the trend of moisture change have been examined using both the original model and the modified model including snow. Both models show similar characteristics over the CONUS for the past three decades. The inclusion of the snow model does not qualitatively change these results, and has little effect on the spatial comparability of the index. Effect of frozen soil has also been examined. In this study, this effect is simply tested by shutting down infiltration when ground is frozen. Due to the time lag between ground status and air temperature (which is the determinant for the calculated snowmelt rate), and also the different spatial resolution for these two data sets, most of the spring snowmelt in western US, especially the northern Rocky Mountain regions didn't infiltrate the soil system and became surface runoff. This loss of moisture caused the soil moisture in those regions decreased from a climate mean 35cm to…

▼ Drought indices are one of the most important elements of an effective
drought monitoring and early warning system. They help to characterize
drought and guide appropriate responses to reduce
drought impacts.
Drought indicators are more useful than raw data in decision-making process, even though each index has specific use and limited by its strengths and weaknesses. The literature review showed the evaluation of
drought conditions by decision-makers as an important issue, but so far no research has been done to understand how decision-makers use diverse and often conflicting values of
drought indices to make
drought declarations. This research studies how
drought declarations by decision-makers relate to
drought indices to measure past two droughts in South Carolina.
The South Carolina
Drought Response Committee (DRC), the state's major
drought decision-making body, evaluates climate data and seven
drought indices to issue
drought status declarations for each county of the state. The case of South Carolina's
drought management program is particular beneficial because the state has one of the largest number of
drought indicators among other state-level programs in the nation. My research determines similarities and differences in measures of
drought between the DRC and multiple
drought indices, such as Palmer
Drought Severity Index (PDSI), Palmer Hydrological
Drought Index (PHDI), Z-index, Standardized Precipitation Index (SPI), Crop Moisture Index (CMI), Keetch-Byrum
Drought Index (KBDI) and the U.S.
Drought Monitor (USDM). Nine years of monthly values of each index are compared with the DRC declarations in evaluating
drought onset, duration, severity and recovery.
The results show that a cumulative approach is more useful in measuring
drought conditions rather than one or two indices. The DRC measures
drought onset 3-4 months later than the majority of indices. The
drought duration of the DRC for overall study period is similar to most
drought indices and longer in comparison to
drought indices within two
drought periods 2000-2002 and 2007-2008. The severity measured by the DRC typically has more moderate months than other indices. The DRC consistently identifies
drought recovery after
drought indices and tends to agree with
drought indices in measuring
drought recovery more often than in measuring
drought onset.
This research aims to benefit the decision-making process for
drought and water managers, government officials, and stakeholders, as it informs
drought assessment in the use of major
drought indices. This research is an assessment of
drought indicators for policy purposes and can be used in advisement for
drought triggers in other regions of the country and the world. Effective use of
drought indices in decision-making process enhances proactive
drought management policies (risk management approaches) and helps to reduce
drought impacts with an ultimate goal of creating
drought resilient societies

▼ Finger millet \Eleusine coracana (L.) Gaertn.] is an important traditional food security crop
in 2 remote and dry areas of northern Zambia. Its several major uses include porridge, bread,
malt, beverages, fodder and popped products. Yields in these areas are severely limited by
drought. Drought is expected to occur with increased frequency and intensity in future with
climate change. Development of tolerant varieties is a more sustainable way to cope with
recurrent drought for small scale growers. Limited research on tolerance to drought in finger
millet in Zambia has been done. As a result only a few varieties adapted to the high rainfall
region have been developed and promoted. Two hundred and fifteen accessions in the
national collection have not been evaluated for the trait. As a result very little is known about
their variability in the trait. Assessment of variability is important for effective selection.
Variation in 12 putative morphological and agronomic traits of drought tolerance in 203
accessions was studied in a wooden box Randomized Complete Block Design off-season in 2
environments, one with and the other without stress, on an Acrisol in northern Zambia. One
sample T-test of differences in attributes of traits showed no significant difference between
test environments in grain weight (GW, p = 0.744). The test, however, showed significant
differences in spike length (SL,/? = 0.027); highly significant differences in biomass (BW, p
< 0.001) and chaff weight (CW,p < 0.001), days to 50 % flowering (DTP,/? < 0.001), pest
and disease susceptibility (PDS, p < 0.007), plant height (PH, p < 0.001), number of
productive tillers (NPT, p < 0.001), spike weight per plot (SY, p < 0.001) and stay-green
characteristic (SGC, p < 0.001). Withholding water for 5 days during flowering reduced SL
by 3.4 %, BW by 3.1 %, SGC by , CW by, PDS by 10.5 %, NPT by 40.0 %), and SY by 48.5
% and increased PH and DTP by 3.1 and 4.3 %, respectively. One-way analysis of variance
detected significant differences among accessions in SY (p = 0.032) under optimal
conditions. The same analysis detected significant differences in number of spikes per panicle
(SN,/p = 0.014) and SGC; and highly significant differences in PDS (p = 0.001) under stress.
Eighty-three accessions outweighed the best check (FMM 165 = 2.500 + 1.000 kg/plot) in SY
under optimal conditions. Accession ZM 3813 had the highest SY (6.450+1.000 kg/plot) and
ZM 203 (0.200 + 1.000 kg/plot) the lowest in the environment. Under stress 92 accessions
exceeded the best check (Nyika = 5.923 + 1.3825 - same and 1.5457 - different block) in SN.
ZM 3825 had the largest attribute (8.706 ± 1.3825, 1.5457) and ZM 193 the smallest (2.631).
In SGC 77 accessions were scored better than the best check, FMM 165. ZM 225 (5.222 +
0.7643, 0.8545), ZM 245 (5.222 + 0.7643, 0.8545), and ZM 112 (4.972 ± 0.7643, 0.8545)
were scored the best and 37 others the poorest in the trait. And in PDS 31 accessions had
better scores than the best check (Senga = 3.000 +0.0151,…

▼ This thesis, with its focus on the Gwembe Valley, an area that has a long history of drought conditions in the country and one of those that was severely affected during the recent three year running drought (.1981-84) , attempts to find out about peoples' responses and adjustments to the drought hazard in the region. It investigates as well, many aspects relating to drought perception. Specifically, the present study was guided by three broad objectives, which sought to:
(i) determine the nature and extent of the drought hazard in the Gwembe Valley, (ii) examine the full range of human adjustments
to the drought hazard, (iii) examine and establish a relationship between
peoples." perception of the hazard and rainfall periodicity as recorded at the rain gauge stations in the study area.
Three main working hypotheses, (from which 41 null hypotheses were formulated and tested using the chi-square test of independence at 0.05 level of significance} were also advanced. These are listed as follows:
1. the awareness of the drought hazard is a function of magnitude, frequency of the hazard, recency and frequency of personal experience.
2. the evaluation and adoption of adjustments to
drought by individuals is the function of the
perception of the hazard and the perception of the
alternatives available.
3. farmers response to drought involves a variety of
simple adjustments, which attempt to work more in
harmony with nature than human control over nature.
In pursuing the study both field and library research were employed. Data from the field was based mainly on an interview schedule survey. This survey was administered to a sample of 180 peasant farmers and the results yielded from it formed the basis of our data analysis, with supple¬mentary information arising from other forms of field inquiry and secondary materials.
The key findings of the study include the following:
Essentially, the people in the study area hold similar views on the drought hazard and practise a wide range of drought adjustments. They look upon droughts as being generated by external physical forces, frequent in their occurrence,
unpredictable in nature and problematic because of their effects on crop production.
The drought adjustments practised by the people are simple in character and are deeply rooted in their agricultural and social systems. They include the planting of drought tolerant crops; millet and sorghum, rain making and the selling of livestock. Except for a few, all the adjustments are of an individual centred nature and are widely viewed as being very useful in mitigating drought effects. The chi-square results generally indicate that several factors (e.g. personal drought experience, the frequency of drought occurrence and socio-economic variables were responsible for the high drought awareness amongst the sample population. But contrary to what was anticipated, the chi-square results fail to pin-point the importance of perception variables in the adoption of drought adjustments.

▼ There has been an increased frequency of drought occurrence in the Gwembe Valley in recent years.The situation, however, has not been addressed adequately due to lack of enough research on drought effects, especially the assessment of appropriateness and effectiveness of the mitigation measures that had been recommended and implemented to reduce the impacts. This study was carried out in
the Gwembe Valley in the period September, 1999 to February 2000, covering the three districts of the valley namely Siavonga, Gwembe and Sinazongwe.The objectives of the research were: (i) to determine the drought characteristics; (ii) to assess drought
impacts on agriculture and water supply and (iii) to determine appropriate measures of reducing drought vulnerability of local communities.Some of the analyzed data was collected from participants who included households of peasant farmers and village headmen. Other data came from civil servants working for the Ministry of
Agriculture Food and Fisheries (MAFF), the Ministry of Education (MOE), Department of
Meteorology in the Ministry of Transport and Communications and also from the Water Affairs Department of the Ministry of Energy and Water Development and from the Ministry of Health(MOH). Civic leaders included Member of Parliament (M.P.) for Gwembe (who was later appointed Deputy Minister for Southern Province) and District Council officials.Both qualitative and quantitative types of data were collected. Interview, questionnaire and
observation methods were used while analysis involved the 'run-methodology' and magnitudefrequency approaches. Results revealed that the droughts were not due to shortfall in expected total amount of rainfall per season alone but that the duration of dry-spells in the rain season and the actual number of rain days per month, contributed. The impacts of the droughts were manifested in crop failure and depleted food stocks. Water scarcity leads to many diseases and livestock deaths.
Human reactions like failure to act quickly in the wake of drought signs, cultivation of inappropriate crop and in some instances, sheer laziness by people who depended on receiving free food-aid
(especially) were among the accentuating factors to hardships local people faced. The study also suggested that drought occurrence was not random and had increased slightly since 1980, impacting agriculture and water supply more severely.The recommendations to individuals emphasized the need to intensify the current mitigation
measures being pursued while government was being urged not to procrastinate in implementing measures suggested to it as this derailed progress. It was observed that triumph in the fight against
drought would need establishing a permanent body for drought mitigation and management. This body should be composed of professionals in matters on drought and who should be ready to address the issue whenever it showed signs of re-surfacing. The other contingency measures already adopted such as food aid and use of drought resistant crop varieties were to…

▼ A field study was conducted at ARC - Grain Crops
Institute, Potchefstroom Experimental Farm and at Taung Crop
Production Center during 2006/07 summer growing season. Twenty
sorghum genotypes were planted in two separate blocks, under full
irrigation and rain fed conditions with plot size of 4 rows x 5 m x
0.9 m giving a density of 55 555 plants ha-1. The experiment was
laid out in a randomised complete block design replicated three
times. The irrigated block received scheduled irrigation from
planting until maturity, while the rain fed block received
irrigation prior to germination only. Agronomic traits measured
were plant height, stem diameter, biomass, flowering date, panicle
exertion, panicle length, leaf area, grain yield, and thousand seed
mass at Potchefstroom and Taung experiments.
Drought susceptibility
index (DSI) was quantified using the formula: DSI = [1 - (Ydi/
Ypi)]/ [1 - (YD/YP)] and %yield reduction (%YR) was calculated
using the formula: %YR = (Ypi –Ydi)/ Ypi x 100. Significant
variations among genotypes with regard to grain yield (GYLD), plant
height (PH), panicle length (PL), biomass (BM), stem diameter (SD),
panicle exertion (PEx), and 1000 seed mass (TSM) were observed at
Potchefstroom under rain fed conditions, while under irrigated
conditions significant variations were only observed for GYLD, PH,
PL, BM, days to 50% flowering (DF), SD, leaf area (LA), PEx and
TSM. At Potchefstroom genotypes varied significantly with regard to
PH, PL, BM, DF, SD, LA, PEx and TSM under rain fed conditions,
while under irrigated conditions genotypes varied with all traits
measured with exception of harvest index (HI) and relative water
content (RWC). At Potchefstroom, soil water deficits significantly
affected GYLD, PH, HI, PEx and RWC, while at Potchefstroom soil
water deficits significantly affected GYLD, PH, SD, LA, PEx, TSM
and RWC. Genotypes varied with their level of resistance/
susceptibility to soil water deficits at both Potchefstroom and
Taung. Some remarkable correlations among traits measured were
observed under rain fed and irrigated conditions and across the
treatments at both Potchefstroom and Taung. At Potchefstroom,
significant correlation was only observed between
drought
susceptibility index (DSI) and PH under rain fed conditions, while
at Potchefstroom negative and significant correlation was only
observed between DSI and GYLD under rain fed conditions. At
Potchefstroom, GYLD under rain fed significantly related to GYLD
under irrigated conditions and across the treatments. However, GYLD
under irrigated conditions significantly related to GYLD across the
treatments. At Potchefstroom, GYLD under rain fed conditions
significantly correlated with GYLD across soil water regimes, while
GYLD under irrigated conditions significantly correlated with GYLD
across the treatments. Genotypes that exhibited the combination of
high yield potential and resistant traits were recommended.
Genotypes that exhibited high resistant traits with low yield
potential were recommended for breeders to incorporate those…

▼ Growth and development of a plant can be affected due
to various biotic and abiotic stresses such as water, salinity,
frost and pathogens. Application of seaweeds and their extracts to
mitigate plant stresses in agriculture is one of the promising
strategies. However, there is less evidence associated with seaweed
extract application on
drought stress management. In the current
study, investigate the effect of brown alga Ascophyllum nodosum
(L.) Le Jolis. extract (ANE) to mitigate
drought stress in tomato
plants using physiological, biochemical and molecular biological
aspects. The results indicated a rapid recovery (85% compared to
30-40% in controls) of ANE treated plants. It also evident high
stomatal conductance , high plant water potential and less wilting
in ANE treated plants over controls. Moreover, ANE treatments
helped in lowering antioxidant enzyme activities, low lipid
peroxidation, low proline accumulation and the lower expression of
stress responsive genes under the stress. In conclusion, it is
evident that ANE treated plants perform well and recover well under
drought stress compare to control plants.

▼ Finger millet (Eleusine coracana (L.) Gaertn.) is a
crop with high nutritional profile cultivated mainly in developing
countries. It is an allotetraploid (2n= 4x= 36 chromosomes), that
belongs to the Poaceae family and has a genome size of 2509 Mbp.
Drought is one amongst other abiotic stresses limiting a plant’s
growth and productivity. In order to better understand the
physiological responses of finger millet to drought, 12 parameters
were studied by subjecting plants to water withholding at 26 DAS
and imparting water stress for 6 days. Analyzing control plants in
parallel indicated that IE 7079 was the most sensitive accession
and IE 5091 was the most tolerant accession to water withholding.
83 accessions of finger millet obtained from ICRISAT was genotyped
using 31 polymorphic simple sequence repeats (SSRs) identified from
transcript assemblies. A total of 152 alleles were generated by
these 31 SSRs, with a mean of 4.9 alleles per locus and mean
polymorphism information content (PIC) of 0.49 Cluster analysis of
these accessions showed considerable genetic variation in the
varieties from different geographical origins. Identified
polymorphic SSRs can be used to further expand the linkage map of
finger millet.

▼ Cool-temperate rainforest occurs widely within south-west and western Tasmania, where it occurs interspersed with buttongrass moorlands. Rainforest is considered to be a climax vegetation, capable of regenerating in the absence of a major disturbance event, such as fire. Rainforest is also considered to be a fire sensitive community, as many rainforest species are incapable of surviving a fire event. Although fire in rainforest is rare, large rainforest fires have occurred in the past. These fire events are likely to increase with future climate change, which may result in a substantial loss of rainforest communities. It is important to understand the conditions under which fire will sustain and spread within rainforest as this will aid in protective measures, such as hazard-reduction burning, and the allocation of resources during a wildfire.
In this study, I ask, under what conditions it would be likely that a fire would sustain and spread within rainforest. In order to do this the flammability and microclimate of a callidendrous rainforest, implicate rainforest and deciduous beech montane rainforest were characterised. The canopy structure and rainfall distribution of the callidendrous rainforest were also examined. There was very little difference in the flammability of live leaf and litter components between the three rainforest communities and adjacent fire tolerant communities, with the exception of the bark component from a Eucalyptus coccifera woodland. Callidendrous and implicate rainforests were cooler, more humid and less windy than adjacent open areas. There was very little difference in temperature and vapour pressure deficit between the deciduous beech forest and the adjacent open area. The distribution of rainfall within a callidendrous rainforest was found to be heterogeneous. Two millimetres of rain was required to saturate the rainforest canopy. On average, 20% of rainfall was intercepted.
The Soil Dryness Index (SDI) is a tool used by fire managers to provide an indication of drought conditions and is also a component of the McArthur Forest Fire Danger Index (FFDI) in Tasmania. Many fire managers believe that the SDI does not perform effectively in south-west and western Tasmania. As a result, the performance of the SDI was looked at in this region, by examining the canopy intercept factor used to calculate rainforest and the relative performance of the SDI between mineral and organic soils. It was found that the canopy intercept factor designated for rainforest within the SDI performed well, and the SDI for rainforest could not be improved by using the canopy intercept rule determined for callidendrous rainforest earlier in this study. It was also found that there was no difference in the way the SDI performed between mineral and organic soils. It was therefore thought that the observed poor performance of the SDI in south-west and western Tasmania is likely to be the result of a poor representation of weather stations in a topographically complex environment.

▼ Climate variability is perhaps the greatest challenge facing the smallholder farmer. Abnormal temperatures and inconsistent rainfall can destroy a season's harvest despite optimal farm management and market opportunities. Yet the effects of such variability are not constant across a landscape. This paper provides an investigation into the spatial distribution of
drought vulnerability across rice-growing districts in India. We show which regions were exposed to
drought from 1999-2008 and determine that rice yields in central and eastern India were most sensitive to the effects of moisture deficit. We explore the effect of certain adaptation strategies in times of
drought, finding that irrigation, fertilizer use, and cropping diversity all have a positive relationship with rice yields. The spatial methods employed in this study suggest that there are clear geographic patterns in how districts respond to
drought, as well as outliers that seem to be more resilient than their neighbors.

▼ Drought and famine are different but they are
interrelated. Famine is more devastating expression of drought.
Drought related with shortage of water when water supply fail short
to suffice different water needs. Large scale shortage of
accustomed food supply over large area which results in to large
scale starvation deaths means famines. As these two phenomenons
have many dimensions and had wide impact on human culture and
society these subjects remained serious concerns of many scholars.
These subjects with its various shades, aspects and attributes
studied in this research. Amartaya Sen and Dreze became Nobel Prize
laureate for their studies on famines and hunger of world. These
two academicians also studied 1970-73 drought as part of their
study of hunger and famine. Recorded history of Indian monsoon
shows that on long run, Indian monsoon is quiet stable. Indian
summer monsoon system is self regulatory hence even after erratic
behavior for two to three years consequently, it again comes to its
equilibrium exhibiting satisfactory performance. Generally monsoon
arrives and performs rainfall every year newlineregularly without
fail. There are certain years in the history of India that recorded
severe droughts some of them resulted in to grave famines. Famines
are not heavenly but worldly creation of state. This postulation
can be tested through the careful analysis of drought and scarcity
related facts. The outlook of people state and legislature to
issues of public importance and especially issues of acute distress
that society and state facing is reflected in historical research.
This research is intended to pursue all these attributes and facets
of 1970-73 droughts. In any historical research researcher is not
suppose to suggest measures to be adopted in future while dealing
in similar kind of crisis that researchers have
pursued.

▼ Drought is a disastrous natural phenomenon and is
generally viewed as a sustained and regionally extensive occurrence
of below average natural water availability either in the form of
rainfall, river runoff or groundwater. Existing methods consider
only a few factors which are not effective for drought mitigation
programmes. The specific objectives are (i) to assess
meteorological and agricultural droughts using rainfall and remote
sensing data; and (ii) to carry out an integrated drought severity
assessment using Analytic Hierarchy Process (AHP) and GIS. Palar
Sub basin encompassing Vellore, located in the North-East part of
Tamil Nadu State, India, was selected to test the methodology.
Paddy is the main crop in the study area and is cultivated in three
seasons namely, Sornawari, Samba and Navarai. Thirty five years of
monthly rainfall data during 1971 to 2005 were analysed for
variation in space and time. The results of IMD method over a
period of time will not lead to an overall idea of drought
proneness in any area as it gives a mixed bag of different
severities of drought. Hence, a frequency based Meteorological
Drought Severity Index (MDSI) was formulated and applied. The
drought severity values were used to generate drought severity map
in GIS environment. The agricultural drought severity assessment
was carried out by developing an Agricultural Drought Severity
Index (ADSI), which involves crop land and fallow land estimation
that were delineated from remote sensing data using NDVI analysis.
Integrated Drought Severity Index (IDSI) was developed in GIS
environment by combining various parameters affecting drought
comprising of spatial and non-spatial data. In this study, a
drought assessment procedure which will take into account of all
the drought causing factors, is attempted and demonstrated. This
might be due to the lack of proper drought assessment procedures
which would truly reflect the field situation of drought of an
area. This thesis addresses that problem.

▼ Lentil (Lens culinaris Medik.) is usually grown in regions where lack of moisture limits its production.
Drought can be a major limitation to lentil production in the Palliser triangle where annual precipitation is about 300 mm. Root growth and distribution play an important role in crop productivity under dry conditions, enabling plants to access water. The goal of this research was to develop appropriate methods for studying the effects of
drought on root and shoot characteristics of a diverse set of lentil genotypes grown in environmentally controlled growth chambers. Two cultivated L. culinaris (Eston and CDC Greenstar) and 5 wild lentil genotypes (L. orientalis IG
72611, L. tomentosus IG 72805, L. odemensis IG 72623, L. lamottei IG 110813, and L. ervoides L01-827A) were grown in Sunshine Mix 4 (SSM4) and Greens Grade® (GG) media under fully-watered and
drought conditions in two growth chambers. SSM4 is a commonly used growth medium at U of S, and GG is known to provide rapid separation of root samples from the growth medium with minimum damage to root systems. Shoot and root characteristics of the genotypes were compared after growing them separately in SSM4 and GG to identify the best growth medium and to compare morphology of different lentil genotypes. The influence of
drought on root and shoot characteristics of the lentil genotypes was investigated separately in each growth medium. Shoot traits measured included plant height, number of nodes on the main stem, total number of leaflets per plant, SPAD value, shoot biomass and transpiration rate. Root traits measured were number of nodules, root biomass, root/shoot ratio, total root length, total root surface area, length density, average diameter, volume, and total number of tips and forks. SSM4 was found to be a superior growth medium relative to GG. Most genotypes had significantly higher plant height, SPAD, shoot biomass, transpiration rate and nodule number when grown in SSM4. This was likely associated with higher N concentration in SSM4 compared to GG. It seemed that N mineralization (conversion of organic to inorganic plant available form) in SSM4 was greater relative to GG. Lens culinaris Eston had the highest shoot biomass compared to all other lentil genotypes when grown in SSM4 under both fully-watered and
drought conditions. However, reduction in root biomass of L. culinaris Eston under dry conditions was significantly higher compared to wild lentil genotypes, an indicator that cultivated lentil genotypes experienced
drought stress. The lowest reduction in root biomass was observed in L. odemensis IG 72623, which makes this genotype a potential candidate for introgression of root characteristics into cultivated lentil genotypes.
Drought caused reduction in number of nodes, total number of leaflets and transpiration rate.
Drought also reduced root/shoot ratio in cultivated lentil genotypes. No significant difference in root/shoot ratio of wild genotypes was observed between fully-watered and
drought conditions, with the exception of L. tomentosus…

▼ Fungal endophytes grow symbiotically inside plants, where some strains promote plant growth and survival under particular abiotic stresses. Tomato (Solanum lycopersicum Var. Rutgers) seeds were inoculated with systemic (also called class 2) fungal endophytes (Alternaria spp and Trichoderma harzianum). These endophytes were isolated from plants naturally growing in salinized-soil in Saskatchewan, e.g. Little Manitou Lake shore, Radisson Lake shore, and Mosaic Belle Plaine tailings area. The effects of colonization with systemic fungal endophytes were studied on growth performance of tomato plants under NaCl and
drought stress. Endophyte-colonized plants had greater fresh shoot biomass than control plants after 20 d of NaCl stress (300 and 500 mM). They also maintained greater fresh root biomass after 10 d NaCl stress (300 mM). After exposure to chronic 100 mM and 200 mM NaCl stress, there was no remarkable difference in plant biomass (both root and shoot) between endophyte-colonized plants and non-colonized control plants. Exposure to NaCl stress altered different aspects of the plants’ physiology such as photosynthetic efficiency, osmolyte adjustment, and reactive oxygen species generation. Photosynthetic efficiency was improved by endophyte colonization during chronic NaCl stress, but decreased significantly during ≥400 mM NaCl stress. Although osmolality of plants increased with the increase of NaCl salinity, there was no effect of endophyte colonization on plant osmolality. On the other hand, reactive oxygen species activity of endophyte-colonized plants was always lower in comparison to non-colonized control plants in response to NaCl stress.
Endophyte-colonized plants growth performance and physiological responses were also determined under
drought. Endophyte-colonized plants had significantly higher shoot biomass in comparison to non-colonized control plants after intermittent
drought and continuous
drought. Physiological responses of plants differed following intermittent and continuous
drought stress. Photosynthetic efficiency of endophyte-colonized plants improved significantly after intermittent
drought, but there was no effect of endophyte colonization on photosynthetic efficiency of plants after continuous
drought. On the other hand, increased proline accumulation and decreased osmolyte concentration were observed in endophyte-colonized plants in response to
drought stress. There was also indication of less reactive oxygen species in endophyte-colonized plants upon
drought stress. Finally, better fluid use efficiency of endophyte-colonized plants was observed, which is correlated to
drought tolerance in endophyte-colonized plants. These results suggest that our systemic fungal endophytes have the potential to improve agriculture and horticulture on salinized and dry soils which are common phenomenon in semi-arid environments.

▼ Drought stress can substantially alter plant metabolism by decreasing plant
growth and photosynthesis. The lack of rapid and reliable screening criteria and
measurement techniques for determining water use efficiency (WUE) of crop plants has
greatly restricted progress in this critical area of crop improvement. In grain sorghum
(Sorghum bicolor L.), WUE was associated with the transpiration ratio [CO2
assimilation (A) / transpiration rate (E), A:E] from leaf gas exchange measurements.
Research is needed to identify
drought effects on plant productivity and to exploit the
use of this knowledge in breeding and agronomic efforts. Therefore, the objectives of
this study were to determine if differences in A:E and other physiological parameters
existed between two selected cotton (Gossypium hirsutum L.) genotypes and to evaluate
the response of cotton genotypes experiencing water stress at two different growth stages
on biomass production and yield.
Two experiments were conducted using two cotton genotypes differing in
drought tolerance. Each experiment was repeated three times in a randomized complete
block design with six replications. In Experiment I, the water stress treatment was
induced by withholding water when the plants reached the 4-node growth stage. The water stress treatment in Experiment II was imposed at early bloom. Gas exchange and
chlorophyll fluorescence measurements were collected during dry-down and recovery
periods to determine water stress effects on plant physiology. Biomass was partitioned
following the recovery period, to examine phenotypic responses of plants exposed to
water stress.
The results of these experiments indicate that A:E is significantly increased as
leaf water potential (ψL) decreases with no differences in A:E between the two
genotypes. Gas exchange measurements showed significant decreases with declining ψL
and significant increases upon re-watering; yet, no differences were observed between
the two genotypes. Chlorophyll fluorescence was not different between genotypes in
either light- or dark-adapted leaves. In Experiment I TAM 89E-51 had a significantly
greater seedcotton yield; however, in Experiment II TAMCOT 22 had the greater yield.
These experiments suggest that the effects of water stress on cotton are a function of the
intensity of the stress and the growth stage in which the stress is experienced.

▼ Several species of oak were used in a series of chamber based experiments. The species of oaks chosen (Quercus alba, muehlenbergii, and virginiana) were selected because they are all emitters of the volatile organic compound isoprene. Isoprene emissions as well as several physiological parameters such as photosynthesis and stomatal conductance were monitored under normal conditions, as well as while stressors such as
drought and high external ozone were introduced. Ozone fluxes to the plants were partitioned into stomatal and surface fluxes for leaves treated with an isoprenoid coating as well as untreated leaves. It was found that the coating on the leaves acted as a strong surface ozone sink, which reduced ozone concentrations in the leaf boundary layer and resulted in significantly reduced stomatal fluxes of ozone. Measurements of
drought stressed specimens displayed significant declines in photosynthesis and stomatal conductance, however isoprene emissions remained constant. This resulted in a significant increase in the percentage of assimilated carbon emitted as isoprene during times of water stress and represented a decoupling of photosynthesis from isoprene production. The level of circadian control over isoprene emissions was assessed for a Q. muehlenbergii specimen by exposing it to constant light for several days. No circadian control over isoprene emissions was noted for this specimen despite past research demonstrating circadian control over isoprene emissions for several other species.
