How to meet the global challenges? • Increase the productivity • Sustainable intensification • Diversification and multi-functionality • Enterprise development • Linking agriculture and rural development

Challenge of Agricultural Research

Need to address complex problems in order to suggest integrated solutions benefitting smallholder farmers

Agroforestry: Integration of trees on farms and in agricultural landscapes

Trees and shrubs for fodder, food, fuel, fence, shelter, construction, medicine, green manure, etc

Forestry – agriculture – agroforestry Changes in functions, e.g. carbon stocks

Overall aim

To assess and quantify some of the multiple functions of agroforestry and identify synergies and trade-offs at field, farm and landscape scale

Add photos of the 3 scales

Multi-functional agricultural system

Produce and provide multiple products and functions - food, other products and services

Ecosystem services (MA, 2005) ; provisioning (e.g. food, fresh water, wood, fuel), supporting (e.g. nutrient cycling, soil formation,

primary production), regulating (e.g. carbon sequestration, biological pest

control, water purification), and cultural (aesthetic, spiritual, educational, recreational)

Combine on-farm biophysical and participatory studies with simulation modelling at different scales; field-plot, farm, landscape

Welcome to the posters

The geographic project area divided into the two project sites: Kisumu (southern part) and Bungoma (northern part) and further subdivided into the 28 administrative locations. Detailed monitoring of 100 farms (stratified selection) since 2009. In an ongoing study 80 control farms in each project site have been included.
