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.

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?".

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.

While the development commu­ nity has recently begun the turn toward climate-sensitive program­ ming, climate-related efforts have focused on big transformations and big polluters. Energy generation and deforestation are easily identified sources of greenhouse gas emissions for which we have data and policy tools, and therefore a certain degree of comfort. Certainly, global emissions are greatly influenced by energy generation, distress­ing rates of deforestation in what remains of the world's tropical forests, and other large sources of greenhouse gas emissions.

Accordingly to the authors It is beyond the scope of this chapter to empirically explore the determinants of the commercialization of agriculture and its impact on poverty; so instead, they will present and discuss some empirical evidence on topics that remain hotly debated regarding commercialization and poverty. In Sect. 12.2, it is investigated how smallholder farmers in northern Vietnam have been affected by the recent food price volatility with respect to their income and consumption levels, while in Sect.

Participatory approaches have been discussed as alternatives to and complementary elements of more conventional research on sustainable land use and rural development in upland areas of Southeast Asia. Following a brief overview of the history of participatory approaches (Sect. 9.1), this chapter discusses the potential and limitations of applying Participatory Rural Appraisal (PRA) tools to field research practice in Vietnam (Sect. 9.2) and of involving stakeholders in priority setting, modeling and environmental valuation in the Southeast Asian uplands (Sect. 9.3).
