“…Moreover, the government must ensure that, local people adopt permanent alternative means of livelihood that would keep them away from the buffer zones of the dams. As the Climatic changes are projected to worsen in the next half century (Chisanga et al 2022), there is also need to adopt whole landscape-based management of catchments in order to have a clearer understanding of biophysical and human dimensions in the management of dams and prevention of such disasters as the Kandesha Dam breakage, Chisola et. al.…”

Despite of undoubtful economic contribution to the nation, sometimes dam causes sufferings due to uncertain breakage. The study investigated the economic effects of the breakage of Kandesha Dam in the far West of Lusaka Business District. It shows that the magnitude and intensity of the impact of dam breaking is dependent on the anthropogenic activities downstream of the dams. The most notable effects of the breaking of Kandesha dam included loss of income (24%), reduced working capitals among community members (14%), due to disturbed business activities resulting from the rampant flooding (12%). Generally, the findings showed diversity of economic effects following the breaking of the dams. The paper recommends regulation of human activities on the immediate downstream in order to minimize the ultimate impact of the dam breaking. Landscape-based assessment of catchment in order to understand the biophysical processes and human activities before siting and constructing dams would potentially reduce the risk of future breaking of dams and, could further immunize several economic losses on both government and community members part.

“…Irrigation is therefore promoted as a way of building resilience and adaptation to the climate change effect [185,186]. According to research conducted by Chisola et al [187], the main stressors on water availability in Zambia were growing rainfall variability, protracted dry periods, decreased rainfall intensity, rising reservoir percentages and irrigated croplands. They also suggested certain adaptation measures, such as more effective agricultural water use and farmer-aided natural regeneration of forest patches, as they are essential to enhancing landscape hydrological processes that increase seasonal water availability.…”

Climate-Smart Agriculture in African Countries: A Review of Strategies and Impacts on Smallholder Farmers

The agricultural sector contributes approximately 10–20% of the total anthropogenic greenhouse gas (GHGs) emissions. Consequently, climate change can negatively affect crop yields and livestock production thus threatening food security, especially in a vulnerable continent like Africa. This review provides an overview of climate-smart agriculture (CSA) practices and their impacts on smallholder farmers in five African countries (Algeria, Senegal, Benin, Nigeria and Zambia). A total of 164 published articles on CSA practices were reviewed. Analysis of extracted data showed that CSA practices are classified as follows: agricultural practices, restoration practices of degraded lands, forest and cropland regeneration practices, practices in the livestock sub-sector, water resources and use of weather and climate information services. Moreover, climate change effects differed alongside strategies adapted from one country to another. Adoption of these strategies was often influenced by financial means put in place by governments, the role of policy legislation, access to climate information and farmers’ intellectual level. To address this deficiency, scientific-outcome-based research should be used to increase the effectiveness of climate adaptation management programs. In conclusion, to enhance the uptake of climate-smart agricultural practices in Africa, this review recommends the use of scientific-research-driven adaptation measures and prioritization of climate change in governments’ agendas.

“…Kaleya River Basin lies between latitude 15 o 40'0'' S to 16 o 20'0'' S and longitude 27 o 30'0'' E to 28 o 10'0'' E. Originating from the Chikankata hills, the Kaleya River flows in the southwest direction and joins the Kafue River north of Mazabuka town (Chisola et al 2020) (Figure 1). It has several tributaries and a total catchment area of 743.52 km 2 .…”

Small reservoirs in arid and semi-arid areas help rural communities to cope with prolonged dry spells. More recently, the construction and operation of small reservoirs has resulted in upstream versus downstream water use conflicts in some river basins. In this regard, bathymetric information could be used as a tool to monitor the available surface water, and minimize or prevent water conflicts. The challenge is that it is difficult to survey a large number of reservoirs using the traditional sounding methods. Despite the availability of new methods of conducting bathymetric surveys, their utilization in Africa is still low, particularly for depth measurements of small reservoirs. This paper presents modern bathymetric survey and analysis techniques applied for quantifying the capacities of small reservoirs, using the case of the Kaleya River Basin in southern Zambia. The objectives of the survey were to: i) create a database of reservoir storage capacities; and ii) introduce an efficient modern approach of monitoring small reservoir storage capacities. A remote controlled Coden hydrographic survey boat equipped with a SONAR device mounted with Trimble OmniSTAR VBS providing DGPS was used to capture and record hydrographic (xyz) data with greater accuracy. Data analysis was done using Surfer 13 Golden software to produce ten contoured bathymetric maps of surveyed reservoirs. From this information, the reservoir capacities were computed, thus providing information on water stored in reservoirs in the basin. It is concluded that the quantification of storage capacity of small reservoirs using SONAR and GIS provides a quicker and cost effective way of obtaining accurate bathymetric data. Such data is important in resolving water use conflicts in river basins and for decision-making in the context of multiple water uses, climate change and or variability.
