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.

Innovations in the agri-food sector are needed to create a sustainable food supply. Sustainable food supply requires unexpectedly that densely populated regions remain food producers. A Dutch innovation program has aimed at showing the way forward through creating a number of practice and scientific projects. Generic lessons from the scientific projects in this program are likely to be of interest to agricultural innovation in other densely populated regions in the world.

Michael Kügler, from the Brussels Office of the EU-Platform of Chambers of Agriculture, presented the EU-Innovation Partnership (EIP),designed to support knowledge transfer, coop-eration, and collective investment, at the 3rd GFRAS Annual Meeting, "The Role of Rural Advisory Services in Agricultural Innovation Systems", 26-28 September 2012, Philippines. He referred to the need to pursue innovation in a cross-sectorial approach, interlinking existing initiatives, facilitating communication, providing value added through networking, and achieving syner-gies.

This paper provides a review of agronomic management practices supporting sustainable crop production systems and intensification, and testifying to developments in the selection of crops and cultivars. The paper also describes crop farming systems taking a predominantly ecosystem approach and it discusses the scientific application of this approach for the management of pest and weed populations.

The central question posed for this Breakout Sub-Session at the GCARD Second Global Conference on Agricultural Research for Development (Punta Del Este, Uruguay, 29 October – 1 November 2012) is "What role smallholder farmers now play and could play in meeting the future needs in food and nutrition security, poverty alleviation and sustainable management of natural resources?".

This presentation is on AgriVIVO, a project aimed at facilitating better networking of individual researchers and the organizations they belong to for better collaborations and less duplication of efforts.

The Agribusiness Innovation Initiative (AII) seeks to contribute to advancing a climate-smart competitive agribusiness sector which will create more jobs and raise incomes for Ethiopians. The AII will contribute toward this objective by identifying innovative growth-oriented entrepreneurs who are pursuing business opportunities based on value addition of agricultural commodities and providing them with a holistic service offering that accelerates their growth and increases their sustainability.

The development of effective agricultural monitoring networks is essential to track, anticipate and manage changes in the social, economic and environmental aspects of agriculture. The authors welcome the perspective of Lindenmayer and Likens (J. Environ. Monit., 2011, 13, 1559) as published in the Journal of Environmental Monitoring on their earlier paper, “Monitoring the World's Agriculture” (Sachs et al., Nature, 2010, 466, 558–560).

Brazilian agriculture is a success story. The country that until the 1960s systematically received food donations from abroad. and up to the 1980s was still a large food importer, had its agriculture profoundly changed. The traditional agriculture that prevailed in Brazil until the 1970s was progressively transformed in the following decades into a modern and highly competitive agriculture based on science.
