This paper compares lessons learned from nine studies that explored institutional determinants of innovation towards sustainable intensification of West African agriculture. The studies investigated issues relating to crop, animal, and resources management in Benin, Ghana, and Mali.The studies showed that political ambitions to foster institutional change were often high (restoring the Beninese cotton sector and protecting Ghanaian farmers against fluctuating cocoa prices) and that the institutional change achieved was often remarkable.

Based on international literature, preliminary experiences in a three-country West African research programme, and on the disappointing impact of agricultural research on African farm innovation, the current paper argues that institutional change demands rethinking the pathways to innovation so as to acknowledge the role of rules, distribution of power and wealth, interaction and positions. The time is opportune: climate change, food insecurity, high food prices and concomitant riots are turning national food production into a political issue also for African leaders.

This report sets out the synthesis of work carried out within the framework of the Sahel and West Africa Club (SWAC) Secretariat Initiative on “The family economy and agricultural innovation: towards new partnerships”. The initiative aimed to stimulate analyses, collect field data and case studies that encourage debates between regional actors, with a view to informing the development of regional policies and actions in order to promote and strengthen producer access to agricultural innovation, where most producers are anchored in the family economy.

In 2011, ICRISAT and Agro-Insight made 10 farmer-to-farmer videos on the control of striga, a parasitic weed endemic to sub-Saharan Africa. As the weed can destroy entire cereal crops, particularly on poor soils, both striga and soil fertility management need to be tackled together, hence the need to develop this comprehensive “Fighting Striga” series. The videos have been translated into 21 languages and over 50,000 copies of the “Fighting Striga” DVD have been printed, with all 10 videos on it.

Sustainable intensification of smallholder farming is a serious option for satisfying 2050 global cereal requirements and alleviating persistent poverty. That option seems far off for Sub-Sahara Africa (SSA) where technology-driven productivity growth has largely failed. The article revisits this issue from a number of angles: current approaches to enlisting SSA smallholders in agricultural development; the history of the phenomenal productivity growth in the USA, The Netherlands and Green Revolution Asia; and the current framework conditions for SSA productivity growth.

Since 2012, hundreds of organisations across West Africa have shown a series of ten videos on Fighting striga and improving soil fertility to farmer groups and rural communities. This paper asks if a village would change its social structure just because they watched these videos? Field research in Mali revealed that the answer is yes, sometimes, especially if they watched the videos in groups and saw other farmers in the videos doing group activities.

Society’s learning capacity in the field of sustainable land resource management is at stake and more emphasis on knowledge management is needed to guarantee that the accumulated knowledge is shared in such a way that the right actors have appropriate knowledge at the right time to take the best decisions. Efficient policies governing structures for national and regional knowledge management need to be formulated and the working procedures of the various actors in the field need to be defined more sharply.

These Proceedings report on the second International Conference of the Convergence of Sciences (CoS) programme in Elmina (2009). The first International Conference was four years earlier in the same location, where it was discussed how to follow up on the findings of the first CoS Programme phase (entitled CoS1 running from 2001 to 2006). The Conference was intended to introduce the focus on “innovation systems”, and how to enhance these systems for smallholder farmers’ development.

West Africa’s smallholders are dynamic and innovative and, if given the opportunity, could easily and sustainably double or treble their productivity. This would have a huge impact on the region’s food security and economic growth. The Convergence of Sciences programme has spent the past decade exploring new pathways for agricultural innovation that focus on enabling smallholders to capture opportunity.
