Modelling sustainability of agropastoral systems in Bolivian arid highlands
In arid regions, agropastoralists must anticipate losses caused by drought.Herd‐management practices, crop diversification, and the relative importance given to both types of production are the most important strategies.In Andean agriculture, risks exist not only for agriculture but for food availability and commerce (Morlon,1989 ; Sautier,1989 in Eldin, 1998).Increasing international demand for quinoa ( Chenopodium quinoa), the principal crop of this region, has multiplied the price by a factor of 15 in 10 years.In consequence,its production has grown,upsetting the balance between crops and livestock in the traditional system.Our main aim was to identify variables needed to model a sustainable production system under new circumstances.
