The paper aims to identify barriers to the development of Learning and Innovation Networks for sustainable agriculture (LINSA). In such networks, social learning processes take place, and knowledge about sustainable agriculture is co-produced by connecting between the different frames and social worlds of the stakeholders with the help of boundary objects. Studying such processes at the interface between different knowledge spheres of research, policy and practice requires a specific methodology.

The CDAIS project has been an accelerator of processes, with results that have spread from community to governmental levels. Those who have been involved consider that CDAIS was a key reason for these changes, having arrived as a springboard in 2015. Of the four partnerships in Honduras, these conversations explore the experiences of potato producers in La Esperanza, Intibucá, home to almost 70% of national potato production. Since 2015, much has changed for them: from a small group of growers, eight associations have become consolidated organisations.

Many of the world’s food-insecure and undernourished people are smallholder farmers in developing countries. This is especially true in Africa. There is an urgent need to make smallholder agriculture and food systems more nutrition-sensitive. African farm households are known to consume a sizeable part of what they produce at home. Less is known about how much subsistence agriculture actually contributes to household diets, and how this contribution changes seasonally. We use representative data from rural Ethiopia covering every month of one full year to address this knowledge gap.

This book summarizes the achievements as well as some of the challenges faced while implementing integrated systems research to support the sustainable development of smallholder farming in the uplands of the Mekong region.
