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.
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 interviews20 households per village, stratified by wealth (n=480)

Diversity of farming systems
Mzimba in Malawi: intensified crop oriented farming systems
-> 40% of the land cultivated
-Cultivated land/hh: 1.7 ha
-Herd size: 1.9 TLU
Nkayi in Zimbabwe: integrated crop livestock systems
-~40% of the land cultivated
-Cultivated land/hh: 2.7 ha
-Herd size: 3.9 TLU
Changara in Mozambique: Extensive livestock oriented systems
-<30% of the land cultivated

Conclusions• Extensive mixed crop livestock systems in southern Africa are a
function of the interplay of national drivers and local factors– Each site has its own opportunities and specific entry points for sustainable
forms of intensification.
• Lessons for R&D – Place farming systems analysis in the context of these drivers– Ensure that interventions are aligned with these influences– Address household resource endowments and farmers aspirations
• Work in progress – Farming systems typologies and household diversity– Technical, institutional and policy options and trade-offs– New approaches that combine stakeholder involvement with economic and
