Assessing physical and economic water productivity in crop-livestock systems

Abstract

Different sources of water are used by farmers to achieve their goals. This is particularly true in the South Mediterranean region, in a country like Morocco. A study was therefore conducted in the Saïss Plain to assess the physical and economic water productivity of mixed crop-livestock systems. The results showed that it is important to shift the focus of analysis on a single crop to overall farm performances. Second, water productivity indicators very often do not reflect the water mix used. The results imply that additional research should be devoted to the sustainability of water uses, with a particular focus on rainfall in the water mix.
