    Located in the arid and semi-arid areas of West Africa, the Sahel has undergone profound changes over the past 50 years. Known for the prevalence of land degradation processes, the Sahel is suffering from the combined negative effects of population growth, human activities and climate variability, resulting in recurrent droughts and the continued decline of natural resources and land productivity.

    The people of the Sahel — that huge region stretching along the southern edge of the Sahara Desert — are still striving to recover from the fallout of the terrible droughts that have afflicted the area since 1973. Drought has shattered the momentum of socioeconomic development in Burkina Faso, Mali, Mauritania, Niger, and Senegal. According to researchers with Burkino Faso’s Institut de l’environnement et de recherches agricoles, “Rural men and women are now struggling to survive in a land that is exhausted, denuded, desiccated, and swept away by the wind and water.”

    Soil and water conservation (SWC) practices like that of erosion control and soil fertility measures were commonly practiced in the semiarid region of southern Mali since the 1980s. The SWC practices were mainly meant to increase water availability in the subsurface, reduce farm water runoff and gully formation and improve nutrient content of the soil, thereby increasing crop yield. Despite such efforts to promote at scale SWC practices, the landscape of southern Mali is still affected by high rates of runoff and soil erosion and low crop yield in farmers’ fields.

    Large-scale agricultural land investments in Africa are often considered solely from the land perspective. Yet land, water and other natural resources are closely interlinked in agricultural production and in sustaining rural livelihoods. Such investments involving irrigation will potentially have implications for water availability and utilization by other users, making it imperative to regard water as an economic rather than a free good.
