Southern Africa: Drastic increases in the demand for agricultural products Source: Adopted from Capacity Development Initiative in Modernizing Food Systems—Michigan State, Makerere, Stellenbosch and Pretoria Universities, 2010) Strong urbanization and income growth Growing food markets and changes in composition (more meat, dairy, fresh and processed food) 5-6 times the marketed food between 2010 and 2050

7. Objectives of this scoping study Use farming systems analysis in the context of national and local drivers. Determine site specific entry points for moving farmers in mixed crop-livestock systems up the development pathways.
8. Study sites and research methods Site selection : Southern Africa - most extensive site Village selection : 8 villages per country Distance from markets and roads Village level surveys : Focus group discussions ~ 30 farmers of different wealth, gender and age per each village (n=24) Household surveys : Quantitative interviews 20 households per village, stratified by wealth (n=480)

The advisory is an interpretation of probabilistic forecast for its agricultural significance Prepared in consultation with met, agricultural research and extension officers It provides location specific and crop specific suggestions that perform well under expected seasonal conditions The Advisory is currently distributed to participating farmers Currently working on an agricultural information system for wider reach and dissemination through FM (FM station Mbaitu is a partner) and other extension agents
