▼ The coke beach instrumented watershed is a reclamation
cover test site constructed in 2005 on top of petroleum coke at the Mildred Lake mine operated by Syncrude Canada Ltd in Fort McMurray, Alberta. Petroleum coke is a by-product of the oil sands extraction process. The
cover system monitoring has shown an annual water loss which cannot be readily accounted for based on a standard water balance analyses. The water loss is most pronounced in late spring/early summer. It is hypothesized that the cause of the enhanced water loss is a result of convective drying of the
cover as a result of airflow from the atmosphere into the underlying coke. This airflow could be the result of density gradients across the
cover system as a result of temperature contrasts between the atmosphere and the coke or could be the result of oxygen consumption processes associated with the oxidation of methane released from the underlying fine tailings. The primary purpose of this study was to design and implement a field monitoring
system to determine whether convective airflow was occurring across a series of trial closure
cover systems overlying petroleum coke, and to utilize the resulting data in a water-loss calculation and determine the effect on the overall water balance for the site.
The coke beach instrumented watershed contains two
cover system trials: a shallow
cover system and a deep
cover system, with nominal
cover depths of 0.40 m and 1.0 m respectively. Each
cover system was instrumented with soil monitoring instrumentation which has been continuously monitored since
cover construction. The shallow
cover system included a meteorological monitoring
system to complete the water balance monitoring. Additional studies have been carried out on each
cover system including regular vegetation monitoring, and hydraulic conductivity testing. The major field research associated with this thesis was the installation and monitoring of differential pressure between the subsurface soil air and the ambient conditions. Three clusters at variable depths (0.4 m, 1.1 m, and 2.0 m) were installed on each
cover system. In addition, air permeability testing of the
cover system and underlying coke was performed to collect more data points for which to assess airflow rates.
The results of the field monitoring program showed that differential pressure gradients existed across the
cover systems relative to ambient conditions, and each
cover system showed enhanced drying during the field monitoring years. The pressure gradients measured at each
cover system were sufficient to induce substantial airflows, with measured differential pressures exceeding 40 Pa during peak periods. However, the estimated airflow rates did not appear to be sufficient to account for all of the enhanced drying observed in the water balance. This lack of airflow is likely a result of low permeability of the
cover system material where the differential pressure systems were installed. However, it should be noted that across both
cover systems, substantial cracking has occurred as a…

▼ The influence of capping soil depth on water dynamics
was investigated at a decommissioned phosphogypsum (PG) stack in
Fort Saskatchewan, Alberta. PG is the a by-product in phosphoric
acid production, a necessary component of phosphorus fertilizer.
Currently, there are no environmental regulations governing the
depth of capping soil required for PG stack reclamation. Time
Domain Reflectometry (TDR), MPS-1 matric potential sensors and
conservative tracer application were used to assess water balance
across capping soil depths. Results from the varying experiments
indicated that an increase in capping soil depth contributed to
greater infiltration of spring snowmelt water resulting in deeper
penetration of the advective water front into the reclaimed system.
Percolation estimates for capping soil depths < 46 cm were
<3% of annual precipitation; however, the temporal variation
in downward flux estimates suggest spring snowmelt is the dominant
event contributing to percolation.

▼ This study was conduced to evaluate biomass yield and nutrient accumulations in millet (Pennisetum typhoides (Burm.) Stapf), jack bean (Canavalia ensiformes (L.) DC.) and guandu (Cajanus cajan, dwarf cultivar), and also intercropping millet + leguminous and their effects on dry bean at different nitrogen fertilization levels. Two phases were used in this study. The first one was settled the experiment using cover plants, in a randomized block design, and four replications. Only guandu presented smaller fresh and dry biomass yield than other treatments. In generally N, P, K e S accumulation was similar to biomass yield. Greatest Ca accumulation was observed with single jack bean. Greatest Mg accumulation was observed in jack bean and millet singles and their intercropping. Single jack bean and its intercropping with millet gave largest B accumulation. Greatest Cu, Mn and Zn accumulation was observed at single millet and its intercropping combinations, and largest Fe accumulation was observed also, at millet at single system and intercropped with jack bean. On the second phase dry bean was sowed under the straws using the same first phase design, including nitrogen levels in split plot arrangement. Millet straw provided greatest dry bean stand. Jack bean single and intercropped provided the largest hundred-grain weight. Nitrogen rate provided negative linear effect for initial stand, and positive effect in hundred-grain weight. Grain number per pod increased until 106 kg.ha-1 N rate and had little reduction after that. There were significant interactions between straws and N rate for plant height, pod per plant and grain yield. Millet + jack bean provided greatest plant height at 115 kg.ha-1 N rate. Pod number per plant had linear and positive effect in all straw types and the greatest values was observed in intercropping combinations in the maximum N rate. The best grain yield was obtained under millet + jack bean in the largest N rate.

▼ ããThe isolation, separation, and self-contained characteristics of island environ-ments form the unique systems of ecology, culture, and landscape. Simultaneously, characteristics such as a lack of available area, high population density, and depend-ence on imports cause high vulnerability and low resilience in these isolated islands. There are 11 islands around Taiwan. Penghu is one of the islands in this area with the highest density. Under the impact of climate change, the vulnerability and the adapta-tion of the islandâs city may be affected. Therefore, Makung City served as a base for this study, which uses field observations and the collection of relevant literature, fol-lowed by spatial analysis methods and vulnerability assessment model analysis to de-termine the vulnerability of Magong City. The studyâs results and recommendations could provide a basis for policy on the island with respect to spatial planning and management.
ããTo determine the sources of vulnerability on the island, vulnerability indicators can distinguish between the environment and society. However, up to now, we have not considered the difference between the islands near Taiwan. Therefore, the gov-ernment could not provide basic data to assess vulnerability. However, according to the limiting data of the vulnerability assessment results, the neighborhoods near the Makung port are in a high vulnerability area. If climate change continues with a sea level rise and storm surges, it may impact buildings near the coastal area of Makung City. In this study, the weight of vulnerability indicators was built by equal concep-tion to analyze the islandâs vulnerability wholly. Therefore, vulnerability research could try to build weight of island vulnerability in the future.

▼ Field trials were conducted in the Vidarbha region of India to investigate the potential for inter-seeded
cover crops in monocropped cotton and evaluate 5
cover crop species for this purpose. The focus was to understand (1) the effects on cotton (yield) and weeds and (2) the performance of the
cover crops themselves. After the living mulches were planted, no further inter-row cultivations or herbicide applications were carried out.
Cover crop stands were cut back when needed to prevent shading of the cotton canopy.
Cover crop biomass production of more than 80 tons ha-1 were observed, however, there were no significant effects of the
system on cotton yields. Sunnhemp was the most promising species among those evaluated; following good emergence, when the
cover crop received 1 to 2 weed-free weeks during the initial growth period, weed densities less than 15/m2 and weed
cover as low as 7% were recorded.

▼ This research is composed of three parts: 1) Adaptation of Soil Judging to Libya, 2) Predicting the classes and distribution of salt-affected soils in Northwest Libya, and 3) Geospatial analysis of land use change in the Savannah River Basin using Google Earth. Soil judging (Evaluation) plays an important role in soil science education. Libya has six soil orders according to the U.S. Soil Taxonomy (Entisols, Aridisols, Alfisols, Inceptisols, Vertisols, and Mollisols) and the most common soil orders are Entisols and Aridisols. A Soil judging (Evaluation) scorecard was tested at two different universities in Libya: The University of Tripoli and University of Zawia. Eighty-two percent of Libyan users were not aware of Soil Judging prior to this study. After completing Soil Judging trials in various locations in Libya, ninety-five percent of those surveyed indicated that Soil Judging is useful to the natural science education. Libya is mostly a dry and arid country, where sodicity and salinity problems are often accelerated by the prevailing climatic condition and geographical setting of the area. A framework was identified for classifying and mapping salt-affected soils in northwest Libya using field measurements (ECe, soil pH, and SAR) and Geographic Information Systems (GIS). The majority of soils in this region of Libya are normal (slight degree of limitation). Twenty percent of the topsoil is saline-sodic (extreme degree of limitation). Land use change and the loss of wildlife habitats are serious issues facing the Southeastern United States. Across the Savannah River basin, the major change of land use was deforestation and reforestation during the entire study period with most of the changes located near lakes and water tributaries.

▼ Among all the constructive elements in waste containment systems (e.g. sanitary and industrial landfills and waste ponds), liners and cover systems have been seen as the greatest concern. In Brazil, the use of compacted lateritic soil for this purpose is widely accepted, due to the great occurrence of this type of soil. At the same time, the proposal of using compacted mixtures of lateritic soil and bentonite for decreasing hydraulic conductivity seems to be attractive. Besides this parameter, the compatibility between the mixture and the leachate (waste liquid) must be addressed. However, few studies were found dealing at the same time with geotechnical and chemical aspects of these mixtures for liner systems. This dissertation presents a geotechnical and geochemical evaluation of two mixtures of a typical lateritic soils and bentonite for liner usage purpose. The proportions used were 3 and 6% (dry weight). Conventional geotechnical characterization was performed, along with mineralogical and physical-chemical characterization. The hydraulic conductivity was evaluated through rigid and flexible wall permeameters. The compatibility between the soil and different chemical solutions was also assessed. The characterization results showed that, as opposed to what was expected, the clay content of the mixtures decreased when related to the natural soil sample. On the other hand, the plasticity greatly increased in the mixture samples. In terms of hydraulic conductivity, only the mixture with 6% of bentonite showed some significant decreasing in this parameter. The results also demonstrated that the bentonite addition improved the compatibility between the compacted mixtures and the chemical solutions tested. Finally, the mixture 6% (dry weight) is suggested for reducing the K parameter of this lateritic soil.
Face à importância de dispositivos que assegurem a proteção ambiental em obras de contenção de resíduos (e.g. aterros sanitários urbanos e industriais, lagoas de disposição etc), os sistemas de selagem basal (do inglês: liners) e de cobertura (do inglês: cover systems) têm sido objeto de grande preocupação. O uso de solos tropicais argilosos compactados para a construção destes sistemas é corrente no Brasil, devido à sua grande ocorrência em nosso território. Ao mesmo tempo, a proposta de misturar estes solos à bentonita pode ser promissora no sentido de diminuir a condutividade hidráulica destes materiais, e assim melhorar suas características técnicas. Além deste parâmetro, assume real importância a avaliação da compatibilidade química entre o solo compactado e os líquidos dispostos, uma vez que alterações pós-disposição são indesejadas. Contudo, ainda são poucos os estudos que tratam ao mesmo tempo de aspectos geotécnicos e químicos de solos tropicais misturados com bentonita para uso em sistemas de selagem. Desta forma, esta Dissertação propõe um estudo integrado congregando aspectos geotécnicos e químicos para a avaliação de duas misturas de um solo tropical tipicamente laterítico e bentonita, cujas…

▼ A consorciação de plantas de cobertura tem sido preconizada com o propósito de conciliar a proteção do solo e favorecer a oferta de nutrientes em sistemas de rotação de culturas. Objetivou-se com este trabalho avaliar a produtividade de matéria vegetal, o acúmulo de N e a relação C/N de fitomassas em diferentes estádios de culturas solteiras e consorciadas de guandu-anão (Cajanus cajan), sorgo (Sorghum bicolor) e milheto (Pennisetum glaucum). O experimento foi realizado na Fazenda Experimental da Unoeste, em Presidente Prudente-SP, durante março e junho de 2006. Utilizou-se o delineamento experimental em blocos aos acaso, no esquema fatorial, com os seguintes tratamentos: monocultivos de sorgo, guandu-anão e milheto, e consórcios de sorgo + guandu-anão, milheto + guandu-anão e milheto + sorgo, com épocas de coleta aos 30, 60 e 90 dias após a semeadura. O milheto foi muito expressivo na velocidade de crescimento inicial, de tal forma que as espécies em consórcio ficaram dominadas, produzindo mais fitomassa nas culturas intercaladas do que em monocultivo. As melhores épocas para o manejo das culturas consorciadas de milheto + guandu-anão e sorgo + guandu-anão foram aos 60 e 90 dias após a semeadura no ambiente safrinha, respectivamente. A consorciação sorgo + guandu-anão apresentou maior equilíbrio na composição da palhada, pois houve mais sincronismo entre as velocidades de crescimento de ambas as espécies. Os monocultivos de gramíneas apresentaram palhadas com relações C/N mais elevadas do que nos consórcios milheto + guandu-anão e sorgo + guandu-anão.
Objected with this work to evalue the vegetable matter production, the accumulation of N and relation C/N of phytomass in different stages of single crops and consortiums of pigeon pea (Cajanus cajan), sorghum (Sorghum bicolor) and millet (Pennisetum glaucum). The experimental was conducted in a Experimental Farm of Unoeste, at Presidente Prudente-SP, during March and June, 2006. It was used the randomized experimental design in blocks, in the factorial scheme, with the followings treatments: sorghum monoculture, pigeon pea and millet, and consortium of sorghum + pigeon pea, millet + pigeon pea and millet + sorghum, with stages of collection at 30, 60 e 90 days after seeding. The millet was more expressive in the initial grouth velocity, so that species in consortium were dominated, and it produced more phytomass in the intercropping than in the monocultures. The best period to handle consortiums of millet + pigeon pea and sorghum + pigeon pea were at 60 and 90 days after seeding in off-season time, respectively. The consortium sorghum + pigeon pea submitted better balance in composition to straw, because there was more timing between growth velocity of both species. The monoculture of grass submitted straw with relation C/N more elevated than in the intercropping millet + pigeon pea and sorghum + pigeon pea.

▼ The present work had for objective to evaluate the effect of different covering crops and the surface liming in no-tillage system, determining the content of dry biomass produced by each one of these species and the effect of the liming on the chemical properties of the soil and its consequent effect in the yield components and the productivity of the winter maize crop. The experiment was lead in period 2003/2004, in the experimental farm of the IAPAR (Paranà State Agronomic Institute), in one soil classified as Eutroferric Red Latosol, in the city of Palotina - PR. The treatments had been constituted of five vegetal covering species (millet, guandu, foxtail millet, association of guandu with millet and pousio), in combinations with and without surface liming. 3,2 t ha-1 of dolomitic limestone had been applied in surface in certain plots, without incorporation. It was determined that the desiccation of green fertilizers would be carried through when the species emitted string beans or panicle. At the moment of the desiccation of the plots the collections of biomass for determination of the production and the speed of decomposition of each one of the species had been initiated, happening again themselves this sampling 15, 30 and 45 days after. Also stratified soil samples had been collected (0 â 0,10 and 0,10 â 0,20 m) in each plot, in the line of sowing of the species, for determination of pH, levels of P, M.O., H + Al, K, Ca and Mg and values of SB, CTC, V% and m%. The sowed maize were the simple modified hybrid AG-9010. The experiment in the field was conducted until being carried through the harvest of the plots and determined the productivity. Also the determination of the components of the production (number of grains for spike, mass of the grains for spike and mass of 100 grains) in function of the vegetal species and application or not of limestone in each plot was carried through. One concluded that, independently of the species of covering, the surface liming is efficient in the correction of the acidity of the soil and increase of pH and levels of calcium and magnesium in the 0 â 0,10 m layer. At guandu plots occurred increase of the level of phosphorus of the soil in the depth of 0,10 â 0,20 m, however this fact must be associated to the liming, a time that this species presents great capacity to acidify of the soil. The Millet presented greater production of dry matter and bigger tax of decomposition, followed for the association of millet with guandu and guandu. Grass mills also presented minor residue production and lesser tax of decomposition during the period of 45 days. The combination of liming more guandu as species of soil covering before the winter maize crop, results in profits in the mass of the spike and mass of 100 grains, with positive consequences in the productivity

▼ presente pesquisa teve como objetivo principal a elaboraÃÃo do diagnÃstico georreferenciado do uso e ocupaÃÃo do solo nas Ãreas de influÃncia direta da Sub-Bacia B1 da grande bacia do rio CocÃ, em Fortaleza, CearÃ, a partir da avaliaÃÃo das condiÃÃes de ocupaÃÃo das APP das oito microbacias constituintes, todas inseridas no meio urbano e muito impactadas pelo avanÃo da urbanizaÃÃo ocorrido nas Ãltimas dÃcadas em Fortaleza. Neste sentido, foi realizada uma busca documental em ÃrgÃos pÃblicos e por intermÃdio da internet, envolvendo legislaÃÃes, relatÃrios, depoimentos e registros cartogrÃficos sobre a Ãrea de estudo, alÃm de diversas visitas de campo, para consolidar as informaÃÃes. Entretanto, a escassez de dados gerou a necessidade de elaboraÃÃo de mapas temÃticos que tornassem possÃvel o diagnÃstico. Assim sendo, com base nas deliberaÃÃes do CÃdigo Florestal, nas ResoluÃÃes n 303/02 e 369/06 do Conama e no Decreto Municipal n 12.450/08, foram elaborados mapas georreferenciados delimitando as APP, utilizando como referÃncia ortofotos dos voos de 2004 e 2010, na coordenada UTM â zona 24S, South American Datum1969 (SAD 69), utilizando o programa ArcGis, versÃo 9.3. Foi verificado que a legislaÃÃo municipal apresenta-se mais permissiva que as deliberaÃÃes federais, diminuindo, na maioria dos casos, as APP desta sub-bacia. Em consequÃncia, observa-se excessiva ocupaÃÃo regular e irregular do solo das APP, ocasionando grandes vazios em relaÃÃo à vegetaÃÃo ciliar. Destaque-se que, mesmo atendendo parcialmente a ResoluÃÃo n 369/06 do Conama, hà intensa impermeabilizaÃÃo da superfÃcie, o que potencializa a vulnerabilidade à degradaÃÃo ambiental da Ãrea. Diante deste cenÃrio, evidencia-se o uso predatÃrio destes recursos naturais, restringindo os usos mÃltiplos e as aÃÃes que fomentem o desenvolvimento sustentado. Desta forma, propÃem-se aÃÃes de recuperaÃÃo e proteÃÃo destes ecossistemas, buscando reequilibrÃ-los, uma vez que tÃm grande importÃncia no contexto paisagÃstico e da melhoria da qualidade de vida da populaÃÃo. Por fim, sugere-se que haja maior compromisso dos ÃrgÃos pÃblicos, por intermÃdio de seus gestores, no sentido de facilitar a acessibilidade Ãs informaÃÃes sobre a problemÃtica ambiental do municÃpio, a fim de que haja maior interaÃÃo entre a academia e a gestÃo pÃblica, gerando informaÃÃes que possam subsidiar as tomadas de decisÃo

The high rate of urbanization coupled with population growth has caused changes in land use and land cover in Bahir Dar, Ethiopia. Therefore, understanding and quantifying the spatio- temporal dynamics of urban land use and land cover changes and its driving factors is essential to put forward the right policies and monitoring mechanisms on urban growth for decision making. Thus, the objective of this study was to analyze land use and land cover changes in Bahir Dar area, Ethiopia by applying geospatial and land use change modeling tools. In order to achieve this, satellite data of Landsat TM for 1986 and ETM for 2001 and 2010 have been obtained and preprocessed using ArcGIS. The Maximum Liklihood Algorithm of Supervised Classification has been used to generate land use and land cover maps. For the accuracy of classified land use and land cover maps, a confusion matrix was used to derive overall accuracy and results were above the minimum and acceptable threshold level. The generated land cover maps have been run with Land Change Modeler for quantifying land use and land cover changes, to examine land use transitions between land cover classes, to identify gain and losses of built up areas in relation to other land cover classes and to asses spatial trend of built up areas. Finally, Land Change Modeler has been run to model land use and land cover changes in Bahir Dar area and to predict future urban land use changes. To achieve this, four model variables that explain urban growth and six land cover transitions were incorporated in the modeling process. Multi-layer perceptron neural network was used to model the transition potential maps and achieved an accuracy of 61%. This result was acceptable to make actual prediction using Markov chain analysis for year 2010. Validation results showed that the model (Land Change Modeler) had a lower accuracy in simulating changes for the year 2010. Generally, the results of this study have shown that there was an increased expansion of built up areas in the last 25 years from 1.5% in 1986 to 4.1 % in 2001 and 9.4% in 2010 at the expense of agricultural areas. The spatial trend of built up areas also showed that there was a growing trend in the western part of Bahir Dar relative to other directions. Therefore, the findings of this study could provide as decision making for urban planning.

▼ Analisar espacialmente a cartografia de ocupação da terra do distrito de Marracuene e áreas circunvizinhas a partir de imagens do satélite Landsat 5 significa interpretar as imagens tidas dos sensores a bordo nestes satélites de épocas diferentes.
A metodologia usada baseou-se na revisão bibliográfica, uso de técnicas de Detecção Remota (DR) e Sistemas de Informação Geográfica (SIG), que além da aquisição e análise espacial permitiram a realização da classificação das imagens da área de estudo, o manuseamento da base de dados (BDCOV250) existente do CENACARTA (Centro Nacional de Cartografia e Teledetecção) e da DNTF (Direcção Nacional de Terras e Florestas).
Neste trabalho foi feita a classificação das imagens de Landsat 5 para os anos de 1991 e 2011 seguindo-se da validação (matriz de confusão) que mostra a qualidade do modelo gerado.
Como produto final foram elaborados mapas de uso e cobertura da terra para os dois anos em análise. Com base nestes resultados foi possível posteriormente fazer a detecção de mudanças o que permitiu verificar as classes que com o tempo mudaram e as que se mantiveram inalteradas.
A cartografia de uso e cobertura da terra baseada em imagens de satélite permitirá aos planificadores tomarem conhecimento sobre a situação actual do distrito, para acções que permitam a criação de meios para conservação, uso racional e consciente dos recursos florestais existentes no distrito.
Analyzing spatially the land occupation cartography of Marracuene district and surrounding areas from images of Landsat 5 satellite means interpreting the images taken of the sensors on board these satellites of different times. The methodology used was based on the bibliographic review, the use of Remote Sensing (RS) and Geographic Information Systems (GIS) techniques, which besides the acquisition and spatial analysis allowed the accomplishment of the classification of the images of the study area, the manipulation of the (BDCOV250) of CENACARTA (National Center for Cartography and Remote Sensing) and DNTF (National Direction of Lands and Forests). In this work the classification of the Landsat images 5, from 1991 and 2011 and the validation (confusion matrix) were done, showing how good the generated model is. As final product, maps of land use and land cover were generated, illustrating the patented classes that allow the visualization of the cartography containing twelve classes (12) that indicate the existence of a change in land use and land cover, which during the period under analysis disappeared well as the classes that were constant in all the analyzed epochs. Land-based satellite imagery and land-use mapping will enable planners to become aware of the current situation of the district for actions that allow the creation of means for conservation, rational and conscious use of forest resources in the district.

▼ Time of planting plays a critical role in nitrogen (N) uptake by rye
cover crop (CC). Even a few days of delay in planting can severely decrease CC performance. Evaluating the amount of N accumulation related to time of planting is critical to the farmer who has to optimize the winter rye planting date based on completion of corn harvest, suitable weather conditions and time availability for fall manure application. Winter rye
cover crop was planted at 6 planting dates in fall from mid August to early October at weekly intervals from 2004 to 2009.
The results suggest that delay from critical planting date (CPD) will decrease rye N uptake dramatically. Suggested CPDs for northwest parts of Massachusetts are not applicable because they are too early (third to fourth week of August). CPDs for central parts of the State are from first to second week of September. Farmers in these zones can take advantage of
cover crop by a better time management and planting no later than vii CPD. In Eastern areas of Massachusetts CPD is the third week of September. By evaluating the effect of planting date on rye growth and N accumulation throughout the State, this model provides a powerful decision making tool for increasing N recovery and reducing nutrient leaching.
Sixteen units of cost effective and accurate automated lysimeters were designed and installed to measure post-harvest nitrate leaching from a rye
cover crop field during the falls and winters of 2007 to 2009. The electronic
system was designed to monitor soil tension and apply the equal amount of suction to the sampling media. Hourly data from soil tension and vacuum applied to the
system were collected and stored by each unit. A safety
system was designed for protecting vacuum pump against unexpected major vacuum leakage events. The controller can be easily reprogrammed for different performance strategies. Other major parts of lysimeter included the power supply systems, vacuum pump, vacuum tanks, sampling jars, suction cups and plates, and electronic valves. The electronic
system showed a very reliable and accurate performance in the field condition.

▼ Crop residues play a vital role in reducing the potential for wind erosion of agricultural soils in arid and semi-arid regions. The residues act via three modes: reducing wind speed, acting as a physical impediment to wind reaching the soil surface, and as an organic matter input to spur aggregation and aggregate stability. The interactions of crop residues, crop rotation systems, and wind erosion factors were studied at three long-term agricultural research sites along an evapotranspiration gradient near Sterling, Stratton, and Walsh, Colorado. The sites have a 30-year history of dryland, no-till management, and are divided into different cropping
system intensities that vary in the frequency of summer fallow periods in the rotation. Crop rotations studied here include wheat (Triticum aestivum)-fallow, wheat-corn (Zea mays) – fallow, and continuously cropped plots with small grains and forage crops including foxtail millet (Setaria varidis) and forage sorghum (Sorghum bicolor). Forage crop and wheat residues were tracked over two growing seasons (2015 and 2016) to estimate the length of time before soil surface
cover fell below a 30% threshold and to create models for residue persistence. Decomposition Days (DD), a calculation that factors in temperature and rainfall to estimate cumulative conditions that favor decomposition, was used to normalize time scales following harvest across sites and years. Wheat residue covered 82% of the soil surface following harvest and summer forage crops covered 56%. Wheat persisted longer, taking 62.5 DD to fall to the 30%
cover threshold, forage crop residue remained above the threshold for 16.6 DD. The decline of forage crop residue
cover followed an exponential decay model. Wheat residue surface
cover had a longer, slower decline and fit a quadratic decay model. Wheat stem heights were taller following harvest and heights declined at a similar or faster rate than forage crops. To assess rotation legacy impacts on soil erodibility, soils were sampled in May 2015 and tested for dry aggregate size distribution, dry aggregate stability, and carbon distribution by size classes and between cropping intensities. No differences were found in the amount of erodible aggregate size fraction (<0.84mm) by cropping
system intensity. The site with the highest amount of clay in the soil displayed a significant difference in aggregate stability by crop rotation, with wheat-fallow rotations having stability of 2.96 ln J/Kg and continuously cropped systems having 2.80 ln J/Kg. Carbon distribution did not differ by crop rotation but did differ by size class at the site with the highest potential evapotranspiration and lowest clay content where the largest aggregates contained the highest proportion of carbon. Every phase (i.e., rotation year) of each of the crop rotation systems were represented each year. There was a significant difference in mean erodible fraction and aggregate stability by cropping phase at the time of sampling at the site with the highest clay content. Taken together, the crop…

▼ A análise de uso e cobertura do solo é uma das etapas fundamentais para realização do planejamento estratégico de conservação de uma bacia hidrográfica. Este trabalho tem por objetivo analisar a paisagem da Bacia Hidrográfica do Rio Tijucas com fins de proposta de áreas prioritárias para implantação de Unidades de Conservação, utilizando como ferramenta o Sistema de Informação Geográfica (SIG), com intuito de fornecer subsídios para proteção dos recursos ambientais. Esta bacia localiza-se no litoral central do estado de Santa Catarina, na 8 região hidrográfica. Em diagnóstico realizado com imagens do satélite TM Landsat no ano de 1985 essa bacia possuía mais de 60% de sua cobertura vegetal em bom estado de conservação, porém esta área passa por uma forte pressão na ocupação urbana, sendo necessárias medidas de proteção à diversidade biológica e recursos hídricos. Para esta comprovação, foram geradas cartas temáticas de hidrografia, uso e cobertura do solo e de Unidades de Conservação existentes. A importância do estudo remete a identificação do uso e cobertura do solo na bacia sendo comprovada a significativa perda de cobertura vegetal nativa que em 1985 representava 62.58% da área total da bacia no ano de 2006, 52,66%, gerando uma perda significativa para a região ao longo de 21 anos. Foi considerado uso inadequado as áreas ocupadas com cultura, urbanização, vegetação exótica, pastagem e campo irrigado representando um somatório de 46,64% dessa ocupação estão em APPs, seria esperado que as margens ao longo dos cursos dágua, protegidas por uma legislação específica, estariam mais próximas ao natural. Evidenciando que a área de estudo está sendo ocupadas de maneira desprovida de planejamento, sem proteção as suas potencialidades e recursos naturais, sendo que a proteção ambiental deveria objetivar a conservação da natureza e todos os elementos necessários à manutenção do equilíbrio ecológico. O método aplicado ao arcabouço do sistema de UCs foi favorável a distribuição das Manchas selecionadas, onde todas as manchas (fragmentos) estudadas têm potencial como valor para a biodiversidade que justificam a implantação de Unidades de Conservação, por isso, estabelecidas como áreas prioritárias. No entanto, entre as quinze áreas, algumas têm maior possibilidade de serem efetivadas devido à mobilização social e/ou conhecimento e interesse do gestor envolvido

▼ As faixas que margeiam os cursos d\'água são áreas protegidas por lei, com a função ambiental de preservar os recursos hídricos, a paisagem, a estabilidade geológica e a biodiversidade, facilitar o fluxo gênico de fauna e flora, proteger o solo e assegurar o bem estar das populações humanas. Atividades antrópicas, principalmente agricultura e pecuária, alteram o uso e ocupação do solo com o consequente desflorestamento de áreas de interesse ambiental. O uso do sensoriamento remoto e do geoprocessamento permite uma analise multitemporal das alterações ocorridas em uma determinada região, possibilitando o monitoramento de áreas legalmente protegidas, em um determinado período. O trabalho em questão procurou realizar um diagnostico da evolução da relação do uso e ocupação do solo com a situação das Áreas de Preservação Permanente (APPs) marginais em um período de 20 anos, da bacia hidrográfica do rio São Jose dos Dourados - SJD (UGRHI-18), no noroeste paulista, utilizando imagens do satélite Landsat-5 sensor TM (Thematic Mapper) de 1990, 2000 e 2010. Para o desenvolvimento do trabalho foi utilizado o SPRING (versão 5.2), que consiste em um software livre de Sistema de Informações Geográficas (SIG) desenvolvido pelo Instituto Nacional de Pesquisas Espaciais (INPE) / Divisão de Processamento de Imagens (DPI). Os resultados obtidos demonstram que a bacia do SJD possui área total de 5.161,94 km2, sendo que 483,22 km2 (9,36%) são APPs marginais. No período estudado ocorreu um aumento da classe \'Vegetações nativas\', que ocupava 9,43% da área total da bacia em 1990, passando para 10,80% em 2000 e 12,95% em 2010. No interior das APPs a classe \'Vegetações nativasócupava 27,60% em 1990, passando para 33,30% em 2000 e 47,61% em 2010. Na área total da bacia, as classes que apresentaram os maiores aumentos de área durante o período estudado foram \'Solo expostoé \'Cana-de-açúcar\', e a que apresentou a maior diminuição de área foi a classe \'Pastagem/Gramíneas\'. Já no interior das APPs, a classe que apresentou os maiores aumentos de área foi a \'Vegetações nativasé a que apresentou a maior diminuição foi a \'Pastagem/Gramíneas\'.
The tracks that border waterways are protected by law, with the environmental function of preserving water resources, landscape areas, geological stability and biodiversity, facilitate gene flow of fauna and flora, soil protection and ensure the well being of human populations. Anthropogenic activities, mainly agriculture and livestock, alter the use and occupation of land and the consequent deforestation of areas of environmental interest. The use of remote sensing and GIS allows a multi temporal analysis of alterations that occur in a particular region, enabling the monitoring of legally protected areas in a given period. The work in status a diagnosis of the evolution of the relationship of the land use and occupation to the of Permanent Preservation Areas (PPAs) marginal in a period of 20 years in the watershed of the Sao Jose dos Dourados - SJD (UGRHI -18), State of Sao Paulo, using…

▼ A microbacia do ribeirão Mestre DArmas localiza-se na porção Norte do Distrito Federal e nos últimos anos vem apresentando um crescimento populacional acelerado. Essa microbacia é responsável pelo abastecimento de água de parte substancial da população residente no DF, e estudos realizados na área vêm demonstrando alterações na qualidade da água dessa região, sendo essas alterações atribuídas ao uso e ocupação inadequada das terras, bem como o lançamento de efluentes domésticos. O objetivo do estudo foi avaliar a ocupação das terras e a qualidade da água na microbacia do ribeirão Mestre DArmas, caracterizando os diferentes tipos de usos e ocupações das terras das sub-microbacias das captações de água da Companhia de Saneamento do Distrito Federal CAESB localizadas nos córregos: Brejinho, Fumal, Quinze, Corguinho e dos ribeirões Mestre DArmas e Pipiripau. Utilizou-se um Sistema de Informação Geográfica e técnicas de Sensoriamento Remoto para a integração das informações acerca da ocupação das terras e qualidade da água. Foram analisados os parâmetros de turbidez, condutividade, amônia, pH, demanda química de oxigênio, coliformes fecais e o Índice de Qualidade de Água, ao longo dos anos 1996, 2000, 2003 e de janeiro a julho do ano 2005, de forma possibilitar a avaliação da sustentabilidade dos usos dos recursos naturais da microbacia do ribeirão Mestre DArmas visando a garantir o desenvolvimento sustentável da região.
Mestre DArmas watershed is located at the North portion of Distrito Federal - DF and in the last years have been presenting an accelerated populational growth. This watershed is responsable for supplying water to a reasonable portion of population which lives in DF, and some studies have been showing that are having some alterations on the water quality of this region, and those are been related to the inadequate land use and land cover, and the sewage. The objective of this work was to evaluate the land cover and the water quality of the Mestre DArmas watershed, identifying the different types of land cover of the sub-watersheds from the public water collection points of Companhia de Saneamento do Distrito Federal CAESB located at small rivers: Brejinho, Fumal, Quinze, Corguinho, Mestre DArmas e Pipiripau. It was used a Geographical Information System and techniques of Remote Sensing to integrate informations about the land cover and the water quality.

▼ Entre os vários nutrientes essenciais na nutrição do milho, sem dúvida, o nitrogênio (N) é um dos mais importantes. No entanto, na maioria das vezes, a quantidade naturalmente disponível no solo é insuficiente para suprir a demanda por N, tornando a complementação com fertilizante nitrogenado no milho fundamental para obtenção de expressivas produtividades, além de representar uma parcela significativa dos custos de produção. Dessa forma, o uso racional de fertilizantes nitrogenados associado ao melhor aproveitamento do N liberado pelos resíduos culturais antecessores é um aspecto de extrema importância para a produção de milho dentro de um cenário agrícola que busca sustentabilidade econômica e que seja ecologicamente correto. Este trabalho teve como objetivo principal estudar a dinâmica de disponibilidade de N no solo influenciado pelo aporte de resíduos de culturas de cobertura antecessoras e avaliar o uso de novas tecnologias no manejo da adubação nitrogenada no milho em sistema plantio direto (SPD). Para tanto, estudos específicos e complementares foram conduzidos, buscando avaliar a dinâmica de decomposição de resíduos e liberação de N (Capítulo I); os efeitos sobre a disponibilidade de N no solo (Capítulo II); a absorção de N no florescimento e a produtividade milho em função da quantidade de resíduos aportados por diferentes culturas de cobertura, combinadas com doses de N em SPD (Capítulo III). Também se avaliou o valor fertilizante do N oriundo dos resíduos de ervilhaca através de técnicas isotópicas com 15N (Capítulo IV) e o uso comparativo de parâmetros de solo e planta na recomendação da adubação nitrogenada a taxa variável no milho, buscando aumentar a eficiência do N aplicado (Capítulo V). As quantidades de resíduos adicionadas ao solo não influenciaram significativamente as taxas de decomposição, mas intensificaram os processos mineralização e imobilização de N. Já o aporte e a dinâmica de decomposição dos resíduos influenciaram diretamente a disponibilidade de N mineral no solo, quando comparado ao não aporte de resíduos. A influência na dinâmica de disponibilidade de N em função de aporte de resíduos ficou evidente nos resultados de acúmulo de N até o florescimento e na transformação deste N absorvido em produtividade de grãos. Os resultados obtidos mostraram que a produtividade milho foi diretamente proporcional à absorção de N e que o milho semeado em sucessão à ervilhaca apresentou maior capacidade produtiva em relação aos resíduos de aveia preta e nabo forrageiro, mesmo com adubação nitrogenada complementar. Produtividades de milho superiores a 9 Mg ha-1 de grãos somente foram possíveis com o acúmulo superior a 150 kg ha-1 de N até o florescimento, sendo que somente na sucessão ervilhaca/milho foi possível alcançar tal quantidade. Porém, apesar da reconhecida capacidade de fornecimento de N pelos resíduos de ervilhaca, associado à capacidade de fixação biológica desta cultura e do elevado aporte de N ao solo, a recuperação de N máxima obtida foi de 27% no primeiro ano e 5% no segundo ano. Assim,…

▼ Les accords mondiaux parrainés par l’ONU pour le développement durable et la réduction des émissions de gaz d'effet de serre, proposent la réduction de la déforestation et l'augmentation de la productivité des zones occupées par les systèmes de production agropastoraux. En Amazonie brésilienne, la déforestation couvre une zone de 760,305.5 km2 en 2014. Les différents usages de la zone déforestée ont des impacts environnementaux et des rendements financiers et sociaux spécifiques. Connaître l'occupation et l'usage des terres ainsi que les systèmes de production prédominants dans cet espace est une condition de base de la planification des actions dédiées au développement durable. Cette étude propose des méthodologies destinées à la cartographie détaillée de l'occupation et de l'usage des terres (LULC), et à l'identification de la régionalisation des systèmes de production agropastoraux. La cartographie LULC de l'Amazonie brésilienne a confirmé les résultats des études antérieures montrant que la plupart des surfaces déboisées sont utilisées principalement pour l'élevage (environ 60%), qu’environ 20% sont couvertes par une végétation secondaire et 5% par l’agriculture annuelle de large échelle. La régionalisation des systèmes de production agropastoraux a été réalisée en deux étapes. La première étape a été effectuée au niveau des divisions administratives municipales, en utilisant des données spatialement explicites de LULC et de déforestation, analysées conjointement avec des données socio-économiques spatialisées au niveau municipal. Les résultats de cette première étape de traitement ont permis d'identifier cinq systèmes de production agropastoraux à l'échelle de l'Etat. La configuration territoriale a ainsi montré que chaque système de production crée différents types de paysages. La deuxième étape a été menée sur des cellules de 10x10 km avec des données spatialement explicites de LULC, de déforestation et une matrice de distance aux infrastructures, et en utilisant des métriques paysagères. Il est alors possible de classer le système de production prédominant dans chaque cellule, et d'identifier l'effet de chaque système de production sur le paysage. Neuf systèmes de production agropastoraux ont été mis en évidence : deux dans les forêts (domaine forestier, phase initiale), trois dans l'agriculture (agriculture stricte, agriculture dominante et aires de coexistence) et quatre dans l'élevage (élevage intensifié pour la viande, élevage non intensifié pour la viande, élevage intensifié pour la viande et le lait et élevage non intensifié pour la viande et le lait). Les méthodologies qui résultent de cette thèse permettront la création d'un système opérationnel de surveillance continu et à faible coût de LULC et des systèmes de production agropastoraux dans les territoires déboisés. Grâce à ce système de surveillance, il sera possible de suivre les impacts des politiques publiques qui visent à un développement durable de la région

▼ The mining of oil sands in the sub-humid region of Northern Alberta, Canada causes large-scale landscape disturbance, which subsequently requires extensive reclamation to re-establish the surface and subsurface hydrology. The reconstructed watersheds examined in this study are located at the Syncrude Canada Limited mine site, 40 km North of Fort McMurray, Alberta, Canada. The three experimental reconstructed watersheds, with nominal soil thicknesses of 1.0 m, 0.50 m and 0.35 m comprised a thin layer of peat (15-20 cm) over varying thicknesses of secondary (till) soil, have been constructed to
cover saline sodic overburden and to provide sufficient moisture storage for vegetation while minimizing surface runoff and deep percolation to the underlying shale overburden. In order to replicate the hydrological behavior, assess the sustainability, and trace the evolution over time of the reclaimed watersheds, a suitable modeling tool is needed. In this research, a model is developed using the
system dynamics approach to simulate the hydrological processes in the three experimental reconstructed watersheds and to assess their ability to provide the various watershed functions. The model simulates the vertical and lateral water movement, surface runoff and evapotranspiration within each watershed. Actual evapotranspiration, which plays an important role in the hydrology of the Canadian semi-arid regions, is simulated using an indexed soil moisture method. The movement of water within the various soil layers of the
cover is based on parametric relationships in conjunction with conceptual infiltration models. The feedback relationships among the various dynamic hydrologic processes in the watershed are captured in the developed
System Dynamic Watershed Model (SDWM). Most hydrological models are evaluated using runoff as the determining criterion for model calibration and validation, while accounting for the movement of moisture in the soil as a water loss. Since one of the primary objectives of a reconstructed watershed is to maintain the natural flora and fauna, it is important to recognize that soil moisture plays an important role in assessing the performance of the reconstructed watersheds. In turn, soil moisture becomes an influential factor for quantifying the health of the reconstructed watershed. The developed model has been calibrated and validated with data for two years (2001-2002), upholding the sensitive relationship between soil moisture and runoff. Accurate calibration of the model based on simulations of soil moisture in the various soil layers improves its overall performance. The model was subsequently used to simulate the three sub-watersheds for five years, with changing the calibrated model parameters to use them as indicators of watershed evolution. The simulated results were compared with the observed values. The results of the study illustrate that all three watersheds are still evolving. Failure to identify a unique parameter set for simulating the watershed response supports the hypothesis of…

The population growth for the last 16 years caused changes in land cover of the Gilgel Abbay watershed, Lake Tana basin, Ethiopia. The effects of the land cover changes have impacted on the stream flow of the watershed by changing the magnitude of surface runoff and ground water flow. This study is mainly focusing on the assessment of the impacts of the land cover changes on the stream flow by changing SURQ and GWQ for the wet months (June, July, August) and dry months (January, February, March) through satellite Remote Sensing (RS) and Geographic Information System (GIS) integrated with the SWAT model. ArcGIS used to generate land use and cover maps from Landsat TM and ETM+ acquired, respectively, in 1986 and 2001. The land cover maps were generated using the Maximum Likelihood Algorithm of Supervised Classification. The accuracy of the classified maps was assessed using Confusion Metrics. The result of this analysis showed that the cultivated land has expanded during the study period of 1986-2001. Using the two generated land cover maps, two SWAT models set up were run to evaluate the impacts the land use and cover changes on the stream flow of the study watershed. The performance of the SWAT model was evaluated through sensitivity analysis, calibration, and validation. Ten flow parameters were identified to be sensitive for the stream flow of the study area and used for model calibration. The model calibration was carried out using observed stream flow data from 01 January 1987 to 31 December 1994 and a validation period from 01 January 1995 to 31 December 2001. Both the calibration and validation results showed good match between measured and simulated stream flow data with the coefficient of determination (R2) of 0.93 and Nash-Sutcliffe efficiency (ENS) of 0.95 for the calibration, and R2 of 0.91 and ENS of 0.90 of the validation period. The result of this analysis indicated that the mean monthly stream flow increased by 16.26m3/s for the wet months while for the dry months decreased by 5.41 m3/s. Generally, the analysis indicated that flow during the wet months has increased, while the flow during the dry months decreased. The SURQ increased, while GWQ decreased from 1986 to 2001 due to the increment of cultivated lands. The model results showed that the stream flow characteristics changed due to the land cover changes during the study period.

▼ Cover crops and grazing under Integrated Crop-Livestock
System (ICLS) can impact the rhizosphere nutrient cycling and may have potential to increase the long-term sustainability and economic profitability of agricultural production
system. In South Dakota, crop production practices and livestock husbandry are both common which provide the opportunity for ICLS to be successful in this region. However, little is known about the impacts of the
cover crops and grazing under ICLS on soil properties in this region. The present study was conducted at South Dakota State University Research Farm (44°20'34.8"N, 96°48'14.8"W), Brookings, SD, to quantify the impacts of
cover crops and grazing on soil bulk density (BD), soil penetration resistance (SPR), soil water retention (SWR), pore size distribution (PSD), total nitrogen (TN), carbon and nitrogen fractions (labile, stable, and inert), microbial biomass carbon/nitrogen, urease and betaglucosidase enzyme activity. Study treatments included grass leaf and broad leaf dominated
cover crop mixtures, both with and without grazing, and the
cover crop control field with no
cover crop or grazing. The experimental site was established on June 2016 by planting of
cover crops and soil samples were collected three times i.e., pregrazing, post-grazing and summer phase at 0- to 5-cm for bulk density, SPR, SWR and PSD; 5- to 15-cm for soil microbial and enzymatic properties. The results showed that one year of
cover crops did not significantly impact the soil bulk density, SPR, carbon and nitrogen fraction (labile, stable, and inert), microbial biomass carbon (MBC), microbial biomass nitrogen (MBN) or urease activity. However, beta-glucosidase enzyme activity significantly increased under broad leaf dominated
cover crop mixtures as compared to grass leaf dominated
cover crops and no
cover crop (control) treatments at the 5- to 15-cm depth. Additionally, cold water extractable nitrogen (CWN) significantly increased under grass leaf dominated
cover crops for the 0- to 5-cm depth. Broadleaf and grass leaf dominated
cover crop mixtures had higher microbial and enzymatic activities as compared to the no
cover crop (control) treatment, but, the differences were non-significant. Grazing treatment significantly impacted soil BD and SWR, PSD, carbon and nitrogen fraction (labile, stable, and inert), MBC, MBN, and urease but beta-glucosidase enzyme activity showed no significant differences at either depth. Sampling time significantly impacted the ρb, SWR, PSD, CWC, HWC, SMC, MBC, MBN, urease enzyme, and β-glucosidase enzyme activities. The present study concluded that one year of
cover crops significantly impacted the selected soil properties i.e., CWN increased under grass leaf dominated
cover crops and soil beta-glucosidase enzyme activity increased under broad leaf dominated
cover crop mixtures as compare to grass leaf dominated
cover crops and
cover crop control treatments at 5- to 15-cm depth. One episode of grazing only significantly impacted only soil BD. Sampling time significantly…

▼ Juvenile rainbow trout Oncorhynchus mykiss stocked into mid-elevation reservoirs in Utah are vulnerable to predation from piscivorous fish and birds. I determined how effectively juvenile trout used
cover to avoid these predators by (1) direct observations (snorkel transects) of habitat selection in two reservoirs and (2) measurements of survival and growth rates in a pond experiment where adult brown trout Salmo trutta were predators. Observations of juvenile trout were conducted within five weeks of stocking in 1988 and 1989. During the day, juvenile trout were abundant in complex inshore habitats and avoided simple habitats such as sand and gravel. Measurements of gut fullness indicated that juvenile trout fed during the day but not during the night. Large Daphnia comprised more than 95% of the diet of juvenile trout. Because large Daphnia were often higher offshore than inshore in both reservoirs, selection of inshore
cover is believed to be primarily a response to reduce predation risk. At night, trout in both reservoirs selected more exposed areas and rested on the bottom. In the pond experiment, the presence of brown trout significantly increased mortality of juvenile trout, decreased their growth rates, and caused them to avoid offshore areas. The presence of
cover significantly decreased predation rates but did not affect growth of the juvenile trout.

▼ Urbanization is occurring worldwide due to the tremendous increase of human population that causes land transformation. As the populations of developed and developing countries continue to grow, the development of new urban areas becomes necessary in order to accommodate the new population. Urbanization, therefore, has become one of the dominant research areas within the Land Change Science research community as researchers and policymakers attempt to manage current urbanized areas as well as future urban expansions. Moreover, utilizing new technologies such as Remote Sensing (RS) and Geographic Information Systems (GIS) to study urban expansions might minimize potentially negative effects of urbanization.

▼ Globally, soil erosion by water is often reported as the worst form of land degradation owing to its adverse effects, cutting across the ecological and socio-economic spectrum. In general, soil erosion negatively affects the soil fertility, effectively rendering the soil unproductive. This poses a serious threat to food security especially in the developing world including South Africa where about 6 million households derive their income from agriculture, and yet more than 70% of the country’s land is
subject to erosion of varying intensities. The Eastern Cape in particular is often considered the most hard-hit province in South Africa due to meteorological and geomorphological factors. It is on this premise the present study is aimed at assessing the spatial and temporal patterns of water-borne erosion in the Umzintlava Catchment, Eastern Cape, using the Revised Universal Soil Loss Equation (RUSLE) model together with geospatial technologies, namely Geographic Information
System (GIS) and remote sensing. Specific objectives were to: (1) review recent developments on the use of GIS and remote sensing technologies in assessing and deriving soil erosion factors as represented by RUSLE parameters, (2) assess soil erosion vulnerability of the Umzintlava Catchment using geospatial driven RUSLE model, and (3) assess the impact of landuse/landcover (LULC) change dynamics on soil erosion in the study area during the period 1989-2017.
To gain an understanding of recent developments including related successes and challenges on the use of geospatial technologies in deriving individual RUSLE parameters, extensive literature survey was conducted. An integrative methodology, spatially combining the RUSLE model with Systeme Pour l’Obsevation de la Terre (SPOT7) imagery within a digital GIS environment was used to generate relevant information on erosion vulnerability of the Umzintlava Catchment. The results indicated that the catchment suffered from unprecedented rates of soil loss during the study period recording the mean annual soil loss as high as 11 752 t ha−1yr−1. Topography as represented by the LS-factor was the most sensitive parameter to soil loss occurring in hillslopes, whereas in gully-dominated areas, soil type (K-factor) was the overriding factor. In an attempt to understand the impact of LULC change dynamics on soil erosion in the Umzintlava Catchment from the period 1989-2017 (28 years), multi-temporal Landsat data together with RUSLE was used. A post-classification change detection comparison showed that water bodies, agriculture, and grassland decreased by 0.038%, 1.796%, and 13.417%, respectively, whereas areas covered by forest, badlands, and bare soil and built-up area increased by 3.733%, 1.778%, and 9.741% respectively, during the study period. The mean annual soil loss declined from 1027.36 t ha−1yr−1 in 1989 to 138.71 t ha−1yr−1 in 2017. Though soil loss decreased during the observed period, there were however apparent indications of consistent increase in soil loss intensity (risk), most notably, in the…
