Environmental and Social Consequences
The construction of the Manantali Dam has had profound environmental and social consequences for the local populations and ecosystems within the Senegal River basin. A significant social impact was the displacement of approximately 10,000 people to make way for the reservoir and infrastructure. This displacement altered traditional settlement patterns and livelihoods, particularly for communities situated along the Bafing river in Mali's Kayes Region. The relocation process required substantial planning to integrate these populations into new or expanded villages, often changing their proximity to key resources such as arable land and water sources.
Health Impacts
Health outcomes in the region have been notably affected by the creation of the reservoir. One of the most significant health challenges is the prevalence of bilharzia, also known as schistosomiasis. The standing water of the reservoir provides an ideal habitat for the intermediate snail hosts of the parasite, leading to increased exposure for local residents who rely on the water for domestic use, bathing, and fishing. This has resulted in higher infection rates in communities surrounding the dam compared to pre-construction levels, placing a continued burden on local healthcare systems and affecting the quality of life for thousands of inhabitants.
Fisheries and Agriculture
The ecological changes brought about by the Manantali Dam have also impacted local fisheries and agricultural practices. The decline in fisheries is a major concern, as the alteration of river flow and sediment transport affects fish spawning grounds and migration patterns. This reduction in fish stocks has impacted both subsistence and commercial fishing, which are critical components of the local economy and protein supply. Additionally, the dam has led to a reduction in flood recession agriculture, a traditional farming method that relies on the annual flooding of the river to deposit nutrient-rich silt on the banks. The regulation of water flow has changed the timing and extent of these floods, thereby affecting crop yields and the agricultural calendar for farmers in the Senegal River basin.
Significance
The Manantali Power Station functions as a cornerstone of the Senegal River Basin's transboundary infrastructure, managed by SOGEM (per operational data).
