In West Africa, many countries are adversely affected by the effects of desertification, land degradation and drought(DLDD), with climate change also increasingly making an impact on local livelihoods. The most visible consequences are a loss of soil fertility and a reduction in agricultural productivity, which can lead to food and social crises and, consequently, to increased poverty. Furthermore, farmers are often forced to exploit the land to its maximum capacity in order to obtain good yields and to avoid the risk of famine. This often increases pressure on natural resources to the point where land is no longer productive and places no longer habitable.
