The objective of this work was to develop a Decision-Support System (DSS) in order to support the decision making process by campesino farmers of Central Mexico. Two biological models, one socio-economic model and a survey database form the DSS. The CERES-Maize model simulated the yield response ...

Part I—Integrating biological and socio-economic models into a holistic system

This paper describes the functioning and validation of the Decision Support Systems described in the first part of the paper. The DSS ran three case studies with different farm sizes that represent the range of farmers found in the Valley. The DSS results were validated against survey data for th...

The livestock sector accounts for 30% of global land area and is a major driver of land use change (Geist and Lambin 2002). Steinfeld et al (2006) calculated that deforestation due to the expansion of pasture and feed crops was responsible for 8% of total anthropogenic Co2 emissions. In addition,...

In the three major maize producing countries in the East African region of Kenya, Tanzania and Ethiopia, up to 44% of the dietary calorie requirements is provided by maize. It is also recognized that livestock are an essential asset of poor farmers in the mixed crop-livestock systems in this regi...
