In order to better assess policy issues and identify those who are being mostly affected by the impact of climate change in cereal production, it is important to discuss the heterogeneity of land ownership. Ninety-five percent of Senegal’s farms are smallholdings, with farm size ranging from 1.5 to 5 ha. The remaining 5% of holdings are larger farms. Large national and international agribusinesses have had a presence in Senegal since at least the 1930s. The largest farms have concentrated operations in the Senegal River Valley, the land around Dakar and coastal areas, and in the Casamance, although agribusinesses have also begun to invest in more remote areas, according to the U.S. Agency for International Development.
