1. Mumba, Makumba Darius. Educational Implications of Damming the Chalimbana River in Chongwe District of Zambia .

Degree: 2011, University of Zambia

Water is a scarce and finite resource with no substitute. All life on earth depends on water. The challenges of water resource management anywhere need concerted efforts by various players such as government, the community or dam owners. This study was aimed at evaluating and describing educational implications of damming the Chalimbana River in Chongwe District of Zambia. In this regard, the study investigated the social impacts of damming the river on the local people. The views and experiences of local people along the Chalimbana River were solicited. Through this study, it is hoped that the source of conflict over the waters of the Chalimbana catchment area would be understood. The study further aimed at designing a proposed educational programme to address conflicts arising from the damming of the same River. This is in view of the fact that education can be used to address human environmental conflicts. The study was both qualitative and quantitative in nature as it captured views and experiences of respondents from which numerical figures were derived. The content analysis method was used to analyse data. In order to achieve the above stated objectives,respondents were purposively sampled and were drawn from the lower Chalimbana River Catchment.Primary information was gathered using separate questionnaires for each of the ten groups of respondents who were: teachers, local people, pupils, agriculturalists, dam owners, forestry officers, water board officials, social workers, the Royal Establishment (Nkomeshya) and headmen. The study found that the major conflicts in the study area arising from the damming of the Chalimbana River were brought about by the following trigger factors: (i) lower catchment areas dried up in the dry season months from August to December of each year. (ii)local people broke dam embankments illegally in order to supply water to their gardens. (iii)over exploitation of water as a common resource by dam owners.With regard to educational implications of damming the Chalimbana River, this study established that topics and issues which needed to be covered should focus on positive and negative aspects of damming the river with emphasis on the sustainability of the river. This study also established that social impacts of damming the river were many, such as the displacement of local people, which led to migration to other areas in search of water as a resource. Arising from the findings of this study, various recommendations have been made, amongst which is the need for a localised environmental education programme to educate people along the Chalimbana River regarding the damming of the river and its sustainability.

2. Mwiinde, Darliet. Cost benefit analysis of sediment and sedimentation in selected small dams in Lusaka and Southern provinces,Zambia .

Degree: 2017, University of Zambia

There are many small dams in Zambia constructed for the purpose of collecting and storing runoff from the catchments. The flow of water into dams is accompanied with sediment resulting from soil erosion within reservoir catchments. The deposition of sediment in reservoirs has implications for their sustainability and thus future water supplies. However, accumulated sediment in reservoirs can be dredged to extend the useful lives of dams. This study aimed at evaluating the burden of sediment and sedimentation in selected small dams in Lusaka and Southern provinces of Zambia. A survey research design was employed to gather data from the sampled dams in Lusaka and Southern provinces of Zambia. A cost-benefit analysis was performed to determine the cost and value of burden of sediment and sedimentation on selected six small dams. A Contingent Valuation of Willingness to Pay was conducted to find out the possibility of local peoples’ support of a possible programme of dredging the accumulated sediment in the reservoirs to restore the lost storage capacities. of the dams. The results of the study showed a clear scenario of the burden of sediment to local communities and the potential restoration of lost reservoir storage capacities to sedimentation. The study established that 25 - 52 percent of studied reservoirs initial water holding capacities had been lost to sediment accumulation in 26 – 60 years of dam operations. The rates of sediment accumulation ranged from 283.92 m3 yr-1 to 29,118.63 m3yr-1, indicating that the surveyed reservoirs had less than 60 years of useful lives beyond the year 2015. Sediment and sedimentation was found to lower the annual benefits from reservoirs intended water uses in monetary terms. The Net Present Value (NPV) for removing and selling the accumulated sediment was found to be high and positive for all the dams while the NPVs for operating reservoirs with sediment in them were found to be low and sometimes negative values were recorded. It is concluded that the studied small dams in Lusaka and Southern Provinces were experiencing severe sedimentation which lowers the benefits from intended dam uses. Because of the high potential benefits that could be derived from sediment, localcommunities and dam owners should be encouraged to exploit this abundant natural resource in their areas.

3. Svensson, Evelina. A Development Communication Perspective on Why Dams Fail : A field study from Zambia.

Degree: Social Studies, 2015, Linnaeus University

Hydropower dams have the potential to provide developing countries with the energy they need for meeting their growing demands, however, they usually bring with them many complex issues. International best practices have addressed problems with dams and provided comprehensive guidelines for how the development of dams can become less problematic and more sustainable. However, there seems to be a gap between the visions and what is actually done in practice. This study aimed to provide more knowledge about this gap by applying a development communication perspective on an ongoing hydropower planning process.   To gather empirical material a minor field study was conducted on the planned Batoka Gorge HES in Zambia in the end of 2014. The study used a qualitative method and conducted interviews with stakeholders that were identified as concerned about the project. This included national governmental institutions, local authorities, traditional authorities, local communities, non-governmental organizations, companies, consultants and journalists. Two different analytical frameworks were used to categorize and analyze the empirical findings, namely the seven types of participation and the monologic and dialogic communication models.   The main findings of this study is that, despite national legislations and international guidelines, which put emphasis on stakeholder engagement, the Batoka Gorge HES still did not fully apply a participatory communication mode. Data revealed intents to use a dialogic communication mode as the regulations propose, however, the communication regarding the project was mainly characterized a monologic mode. The study thus provides empirical findings that confirm and demonstrate the gap between theory and practice, and further suggest that additional research in this field is needed.
