Book Description
This paper investigates the relationship between adoption of modern rice varieties and rice varietal diversity on household farms in Bangladesh. As shown in previous studies, adoption of modern varieties depends on agroecological- and input-related factors, including the availability and use of irrigation facilities, such as tubewells. Having irrigation affects the diversity index significantly and positively, which could be due to the diffusion of more modern varieties (MVs) in areas where irrigation is available and accessible.

Book Description
This book contributes to the adoption of agricultural technology in general and to literature on the System of Rice Intensification (SRI) in particular by identifying the factors that influence the decision to adopt SRI and examining SRI’s impact on household income and yield. The study also discusses the importance of SRI in achieving higher rice productivity and food security. Conducted on behalf of the Government of India’s Ministry of Agriculture from October 2014 to March 2016, the study collected detailed and extensive household-level data. As the second largest producer and consumer, India plays an important role in the global rice economy. Food security in India has been traditionally defined as having a sufficient supply of rice at an affordable price. However, in recent years rice cultivation in India has suffered from several interrelated problems. Increased yields achieved during the green revolution period and with the help of input-intensive methods involving high water and fertiliser use are now showing signs of stagnation and concomitant environmental problems due to salinisation and waterlogging of fields. Water resources are also limited; as such, water for irrigation must contend with increasing industrial and urban needs. As a result of all these factors, rice farmers have experienced a downturn in productivity growth. Since increasing the area of rice cultivation is not feasible, the additional production has to be achieved using less land, less water and fewer additional inputs. The new intensification methods for rice cultivation known as the System of Rice Intensification (SRI), which originated in Madagascar, offer a promising systemic approach to enhancing rice production at affordable costs by simultaneously reducing input requirements and causing less harm to the environment. The SRI approach is expected to enhance yield and substantially reduce water and other input requirements by altering plant, soil, water and nutrient management practices. With SRI taking firm root in India, the book examines and analyses the adoption and the economic impact of SRI in three major rice producing States of India: Karnataka, Madhya Pradesh and Orissa.

Book Description
Water, energy and food are key resources to sustain life, and are the fundamental to national, regional and global economies. These three resources are interlinked in multiple ways, and the term “nexus” captures the interconnections. The nexus has been discussed, debated, researched, and advocated widely but the focus is often on the pairings of “water-energy” or “water-food” or “energy-food”. To really benefit from the nexus approach in terms of resource use efficiency it is essential to understand, operationalize and practice the nexus of all three resources. As demand for these resources increases worldwide, using them sustainability is a critical concern for scientists and citizens, governments and policy makers. Volume highlights include: Contributions to the global debate on water-energy-food nexus Examples of the nexus approach in practice from different regions of the world Perspectives on the future of the nexus agenda Water-Energy-Food Nexus: Theories and Practices is a valuable resource for students, research scholars and professionals in academic institutions with strong interests in interdisciplinary research involving geography, earth science, environmental science, environmental management, sustainability science, international development, and ecological economics. The volume will also be useful for professionals, practitioners and consultants in /NGOs, government, and international agencies.

Book Description
This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

Book Description
First published in 1989, this book deals with the impact of cereal production upon the Third World, specifically ‘Modern Varieties’ (MVs). Using evidence from plant breeding, economics and nutrition science, the authors seek to pinpoint what has been achieved, what has gone wrong and what needs to be done in future. Although the technical innovations of MVs mean more employment, cheaper food and less risk for small farmers, the reduction in crop diversity increases the risk of danger from pests and though MVs enlarge cereal stocks, many are too poor to afford them. The book concludes that technical breakthroughs alone won’t solve deep-rooted social problems and that only new policies and research priorities will increase the choices, assets and power of the rural poor.
