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.

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.

A challenge for researchers and other developers of new technologies in agriculture is to find ways of communicating their results and recommendations. This challenge is particularly acute in regions in which farmers have limited access to education and where illiteracy is widespread, such as in the rural areas of Mali. One approach that shows potential, yet remains largely unused by extension services, is the dissemination of educational video on mobile phones with video and Bluetooth technology, which are widespread in the region.

Over the years, CTA has contributed to building ACP capacity to understand innovation processes, strengthen the agricultural innovation system and embed innovation thinking in agricultural and rural development strategies. The CTA Top 20 Innovations project set out to prove that innovation is taking place in ACP agriculture and in the process has demonstrated that smallholder farmers are beneficiaries as well as partners in agricultural innovation.

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.

Land and property rights, migration, and citizenship are complex issues that cut across all social, economic, and political spheres of West Africa. This paper provides an overarching scoping of the most pressing contemporary issues related to land, migration, and citizenship, including how they intersect in various contexts and locations in West Africa. The way issues are analytically framed captures structural challenges and sets them against the regional and global meta-trends of which policy makers and practitioners should be aware for conflict-sensitive planning.

In Ethiopia, village surveys were conducted in six villages and two expert workshops were organized to discuss the organization of the study and to evaluate the draft results. Based on household surveys, focus group discussions, and institutional stakeholder interviews, we assessed household vulnerability, analyzed the strategies households adopt to reduce the hazards faced, and evaluated the assistance households receive from institutions. Vulnerability profiles were formulated, which show that household vulnerability differs substantially among and within villages.

The objective of this report is to identify and evaluate best practices in smallholder private irrigation in West Africa. The report is based on a comparative assessment of the smallholder private irrigation subsector in Burkina Faso, Mali, Niger, and Nigeria, which included a literature review, field visits, and workshops at both national and regional levels. The task lists for the assessment is provided in annex one. This report first presents the main features of smallholder irrigation and the development projects that have promoted its use in West Africa in chapter two.
