The Great Lakes region of Central Africa is an area abundant in hills, people and conflicts. Its high altitude and cooler climate make it ideal for agriculture. But soils have been exhausted, spare land is no longer available, and farm households in parts of this region rank among the most food insecure and malnourished on earth. Years of civil conflict have moreover paralyzed agricultural advisory and extension services and resulted in poor access to markets.

A platform of farmers, retailers and service providers, civil society organisations, NGOs, government officials, and researchers improves livelihoods in Rwanda. Through interaction and collaboration, these groups experiment with various technological and institutional innovations, thereby tackling local agricultural challenges. This experience illustrates the importance of institutionalising a space where knowledge can be co-created

This case study zooms in on multi-stakeholder processes in the East and Central Africa (ECA) Action Area or Flagship that were launched on 20 May 2013 in Bukavu, DR Congo. The ECA Flagship encom-passes the Rwanda, DR Congo, Burundi, Uganda, Kenya and Ethiopia Action Sites. More specifically, the case study describes and reflects upon the first two years of CGIAR Humidtropics in DR Congo. aiming to outline the multi-stakeholder process as it unfolded and highlight lessons that can be learned from this.

The evidence base on agri-food systems is growing exponentially. The CoSAI-commissioned study, Mining the Gaps, applied artificial intelligence to mine more than 1.2 million publications for data, creating a clearer picture of what research has been conducted on small-scale farming and post-production systems from 2000 to the present, and where evidence gaps exist.

A range of approaches and financial instruments have been used to stimulate and support innovation in agriculture and resolve interlocking constraints for uptake at scale. These include innovation platforms, results-based payments, value chain approaches, grants and prizes, incubators, participatory work with farmer networks, and many more.

Innovation for sustainable agricultural intensification (SAI) is challenging. Changing agricultural systems at scale normally means working with partners at different levels to make changes in policies and social institutions, along with technical practices. This study extracts lessons for practitioners and investors in innovation in SAI, based on concrete examples, to guide future investment.

A huge increase in investment in innovation for agricultural systems is critical to meet the Sustainable Development Goals and Paris Climate Agreement. Most of this increase needs to come from reorienting existing funding for innovation. However, understanding whether an investment will fully promote environmentally sustainable and equitable agri-food systems can be difficult.

Finance is a key lever for turning agriculture from a potential source of environmental harm and social inequity to a driver of conservation and social inclusiveness. Private and public sector funding for farmers to combat climate change and protect and restore nature (‘Paying for Nature’) is rapidly increasing. Yet this new funding may not reach its aims without drastically improving farm-level reward mechanisms.
