In sub-Saharan Africa, there is increasing interest for the adaptation and use of the innovation systems approach to advance learning and development in the Agricultural Research and Development (ARD) sector. This crave is constrained by unavailability of a proven blue print that describe the paradigm shift from the linear approach and how such could function under different socio-economic, cultural and political climate.

This paper sets out to determine the impact of Integrated Agricultural Research for Development in three selected countries of Southern Africa. Agricultural productivity in Southern Africa faces several challenges, of which poor soil fertility strikes out as the priority problem inhibiting increased productivity in farmers’ fields. While several soil fertility management technologies are being promoted in the region, their uptake by smallholder farmers remains very low.

One of the very numerous decisions that smallholder farmers face world wide relates to market participation inagricultural markets and, consequently choosing the appropriate marketing channel for their agricultural produce.Such decisions impact on their incomes and subsequently on their welfare. The objective of this study was todetermine how a multi-stakeholder innovation platform approach influences pigeon pea (Cajanus Cajan L.)marketing decisions in smallholder farming in Malawi.
