Methodology

In addition to experts opinions, the methodological approaches that were used in this study are as follows:

Data collection was conducted in three phases:

  • Documentary retrievals allowed for the collection of all documents likely to contribute to the document that takes into account all the elements of the terms of reference of the study. This data was collected for each locality.
  • Holding of village assembly meetings: the consultants went to the sites to carry out dialogues with the water resource users. To this end, a general assembly meeting was held at each of the three sites in the presence of all social groups of the population, to collect data on potential water resources (underground and surface) and the population's essential needs from these resources.
  • Analysis: data collection was followed by its analysis and a comparison of the data in order to select the most reliable data. The documentary analysis was made in three parts: climate data, agro-sylvo-pastoral data and socio-economic data. After documentation analysis, information collected during the general meetings held in villages, was also analyzed.
  • Starting from a baseline situation (the reference climate scenario) the average of the main climate parameters (temperature, rainfall, wind speed, etc.) over the period 1971 to 2000 were determined. The main elements for characterizing water resources (underground and surface) available in the three sites were determined. Then, an assessment of water requirements for the various socio-economic activities (agriculture, livestock, handicrafts, market-gardening, etc.) was carried out in the three sites. Finally, the comparison of each use of the available and potential water (underground and surface) and demands for meeting the main socio-economic requirements, suggested whether the existing potential supply met all the requirements and if yes, with what limitations.
  • This same approach was used in the case of a climate change scenario where the main meteorological parameters concerning the three sites stem from a climate change model built for Mali. This analysis allows for determining for this temporal horizon, and the impacts of the climate change scenario on water resources in the three sites.
  • Finally, the knowledge of the potential impacts of climate change will allow for formulating the most appropriate adaptation options for each site in the field of water resources.
