This presentation concerns the key property rights issues arising in the West African Semi-Arid Tropics (WASAT). The WASAT contains three main agro-climatic zones: Sahel (300–600 mm of annual rainfall falling in 2.5–4 months); Sudanian (600–900 mm, 4 to 6 month rainy season); and Guinean (900–1100 mm, 6–7 month rainy season). The author presented a conceptual framework to explain the responses that farmers in the WASAT region have adopted to deal with changes in their environment.
