Today, it is known and accepted worldwide on a scientific and human level that the negative impacts of climate change are sources of economic and ecological disruption, degrading people's living conditions. This truth is difficult to accept, especially for populations in developing countries, where poverty limits the means of action available to cope with the multiple negative impacts of climate change: -desertification, reduction of mangroves and other spawning grounds, loss of arable land and other pastures; - salinization of waters, reduction or inadequate availability of water for irrigation and drinking and other productive activities. As Senegal is a poor country, where rural populations live intensely in poverty, there is a need for a better understanding of climate change, in order to develop measures to adapt to this vulnerability.
