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 legally binding agreements to reduce greenhouse gas emissions, conserve biodiversity and increase agroecological practices, who are looking for research-based evidence to guide policymaking and implementation.

Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

To feed a world population that will exceed 9 billion by 2050 requires an estimated 60% increase over current primary agricultural productivity. Closing the common and often large gap between actual and attainable crop yield is critical to achieve this goal. To close yield gaps in both small and large scale cropping systems worldwide we need (1) definitions and techniques to measure and model yield at different levels (actual, attainable, potential) and different scales in space (field, farm, region, global) and time (short and long term); (2) identification of the causes of gaps between yield levels; (3) management options to reduce the gaps where feasible and (4) policies to favour adoption of sustainable gap-closing solutions. The aim of this publication is to critically review the methods for yield gap analysis, hence addressing primarily the first of these four requirements, reporting a wide-ranging and well-referenced analysis of literature on current methods to assess productivity of crops and cropping systems.

The purpose of this book is to present a comprehensive picture of the role of rice in the food and agricultural sectors of Asian nations.
