Closing Rice Yield Gaps in Asia : Innovations, Scaling, and Policies for Environmentally Sustainable Lowland Rice Production

This open access book contributes not only to the scientific literature on sustainable agricultural development and in particular rice agriculture but also is highly valuable to assist practitioners, projects, and policymakers due to its sections on reducing carbon footprint, agricultural innovations, and lessons learned from a multi-country/multi-stages development project.

The scope of the book is conceived as a detailed documentation of the implementation, dissemination, and impact of the CORIGAP project in Sri Lanka, Myanmar, Thailand, China, Vietnam, and Indonesia, with spill-over to Cambodia and the Philippines. It pulls together actionable research findings with the experience of bringing these findings into use. The aim of the book is to provide a wide array of pathways to impact for sustainable rice production in lowland irrigated rice-based agricultural systems. The book is written by local actors of the rice value chain, researchers, and engineers working on a range of best management practices, climate-smart rice production innovations, knowledge translation, and dissemination, as well as decision-making and policy aspects. It is envisioned that the contents of the book can be translated into messages that can help farmers, extension workers, policymakers, and funders of agricultural development, decide on implementing best management practices and climate-smart technologies in their agroecological systems by presenting the technological/practical options along the rice value chain and the partnerships and business models required for their implementation. The book is aimed at practitioners, extension specialists, researchers, and engineers interested in information on current best management practices, sustainable, and climate-smart rice production and constraints that need further investigation. Furthermore, the book is also aimed at policymakers and agricultural development funders required by public opinion and legallybinding agreements to reduce greenhouse gas emissions, conserve biodiversity and increase agroecological practices, who are looking for research-based evidence to guide policymaking and implementation.

Dr. Melanie Connor is a senior scientist at the International Rice Research Institute, specializing in behavioral science and international development. Dr. Connor's research primarily focuses on decision-making in agriculture and rural development, specifically on food system transformation and crop diversification to address climate change challenges, biodiversity loss, the reduction of natural resources, and the triple burden of malnutrition. She has been part of Phases II and III of the CORIGAP project focusing on documenting the outcomes and impacts and harnessing the lessons learned.

Engr. Martin Gummert is an agricultural engineer and was a senior scientist leading the Postharvest and Mechanization Cluster of the International Rice Research Institute until 2022. He advocates for better postharvest management to improve the quality of rice and reduce losses caused by spoilage and pests. His time at IRRI centered on extracting more value from rice harvests through improved quality, processing, market systems, and new products. In 2020, he became the project coordinator for the Closing Rice Yield Gaps in Asia with Reduced Environmental Footprint Project (CORIGAP), funded by the Swiss Agency for Development and Cooperation (SDC). He supported all the knowledge management initiatives and impact documentation until the project closed.

Dr. Grant Singleton was a principal scientist at the International Rice Research Institute until 2019, a visiting Professor at the University of Greenwich, UK, and an adjunct professor at Northern Arizona University, USA. Grant was the coordinator of the Irrigated Rice Research Consortium (IRRC) and the Closing Rice Yield Gaps in Asia with Reduced Environmental Footprint (CORIGAP) Project funded by the Swiss Agency for Development and Cooperation (SDC) until his retirement. A world expert in ecologically based rodent management, Dr. Singleton is also involved in cross-cutting research in natural resource management.
