Mali is one of the largest cotton producers in Africa, but the cotton sector is unstable since the late nineties as a result of decreasing cotton prices. Keeping livestock is profitable and many cotton farmers switch to livestock farming. Different integrated farming strategies are analysed to see which strategy is the most profitable. Each farming strategy involves different areas of land allocated to cotton and cowpea production. Cotton is produced for sale, cowpea for cattle feed. Also, profits for each farming strategy are analysed in case cotton and milk prices fluctuate with 15%. Strategy 2 (cattle is kept in a stable in the hot dry season and is supplemented with cowpea (3 kg cow-1d-1), cotton seed cake (2 kg cow-1d-1) and crop residues (3 kg cow-1d-1), 27% of land is allocated to cotton production, 11% to cowpea production) was most profitable, also when milk and cotton prices fluctuated. Finally it was analysed how livestock herd size changed over time for different farming strategies and how much herd size could grow before pastures were overgrazed. This was 38 years for strategy 0 and 10 years for strategy 3.
