This report shows the result of a study aiming to develop techniques and appropriate approaches of harvesting and utilizing rain water to improve access to water and food security in dryland areas in Mali.
Two NGOs who are members of DCG (AMADE et AEN) tested two different types of rain water harvesting and storage systems, based on the ‘Barefoot College’ and the ‘Rain Foundation’, in six different sites: (i) Region of Koulikoro: Nara (ii) Region of Timbuktu: Birchanga, Tindjambane, Djeigalia and Tassakane and (iii) Region of Gao: Zalablabe.
The features of each of the sites were assessed, and the evaluations showed that the tanks were well-designed and placed in order to capture rain water. Village committees were set up and the members educated for efficient and sustainable management. Taking into account the precautions or measures recommended, these collection and storage systems are an alternative solution for the supply of drinking water for poor and disadvantaged in poor areas. It was verified that the rain water collected from the physical-chemical point of view held the quality of drinking water. On the bacteriological plan precautions and measures would avoid possible contamination.
