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
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
India is one of the fastest growing countries in the world. However, high economic growth is accompanied by social stratification and widening economic disparity between states. This book illustrates some important aspects of underdevelopment and the process by which the underclass is left behind by focusing on the country's most neglected regions.

Book Description
Genetic erosion is the loss of genetic diversity within a species. It can happen very quickly, due to catastrophic events, or changes in land use leading to habitat loss. But it can also occur more gradually and remain unnoticed for a long time. One of the main causes of genetic erosion is the replacement of local varieties by modern varieties. Other causes include environmental degradation, urbanization, and land clearing through deforestation and brush fires. In order to conserve biodiversity in plants, it is important to targets three independent levels that include ecosystems, species and genes. Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions. Chapters in this book are written by leading geneticists, molecular biologists and other specialists on relevant topics on genetic erosion and conservation genetic diversity in plants. This divisible set of two volumes deals with a broad spectrum of topics on genetic erosion, and approaches to biodiversity conservation in crop plants and trees. Volume 1 deals with indicators and prevention of genetic erosion, while volume 2 covers genetic diversity and erosion in a number of plants species. These two volumes will also be useful to botanists, biotechnologists, environmentalists, policy makers, conservationists, and NGOs working to manage genetic erosion and biodiversity.

Book Description
More Food: Road to Survival is a comprehensive analysis of agricultural improvements which can be achieved through scientific methods. This reference book gives information about strategies for increasing plant productivity, comparisons of agricultural models, the role of epigenetic events on crop production, yield enhancing physiological events (photosynthesis, germination, seedling emergence, seed properties, etc.), tools enabling efficient exploration of genetic variability, domestication of new species, the detection or induction of drought resistance and apomixes and plant breeding enhancement (through molecularly assisted breeding, genetic engineering, genome editing and next generation sequencing). The book concludes with a case study for the improvement of small grain cereals. Readers will gain an understanding of the biotechnological tools and concepts central to sustainable agriculture More Food: Road to Survival is, therefore, an ideal reference for agriculture students and researchers as well as professionals involved sustainability studies.

Book Description
This book presents the history of, and current approaches to, farmer-breeder collaboration in plant breeding, situating this work in the context of sustainable food systems, as well as national and international policy and law regimes. Plant breeding is essential to food production, climate-change adaptation and sustainable development. This book brings together experienced practitioners and researchers involved in collaborative breeding programmes across a diversity of crops and agro-ecologies around the world. Case studies include collaborative sorghum and pearl millet breeding for water-stressed environments in West Africa, participatory rice breeding for intensive rice farming in the Mekong Delta, and evolutionary participatory quinoa breeding for organic agriculture in North America. While outlining the challenges, the volume also highlights the positive impacts, such as yield increases, farmers’ empowerment in the innovation and development processes, contributions to maintenance of crop genetic diversity and adaptation to climate change. This collection offers a range of perspectives on enabling conditions for farmer–breeder collaboration in plant breeding in relation to biodiversity agreements such as the Plant Treaty, trade agreements and related intellectual property rights (IPR) regimes, and national seed policies and laws. Relevant to a wide audience, including practitioners with experience in plant breeding and management of crop genetic resources and those with a broader interest in agriculture and development, as well as students of international cooperation and development, this volume is a timely addition to the literature.

Book Description
Between 1991 and 2010, Dhaka’s population more than doubled to 15 million. Simultaneously, the city’s contribution to the national economy almost trebled. Clearly, population growth was accompanied by an unmistakable trend of economic growth, and a significant decline in urban poverty and income inequality. On the other hand, Dhaka’s high population density exacerbated serious environmental challenges, and it was soon ranked as one of the world’s least livable cities. In the context of these contradictory signals of rapid urbanization, Dhaka’s Changing Landscape sets to answer three most intriguing questions: Are the poorer segments of urban population, which migrate with dreams for better lives, benefitting from positive economic trends? Are these benefits sustainable? Are these benefits creating scope for this group to have a stake in the city’s growing prosperity? By studying 600 households and applying comparative analysis over a span of 20 years, the authors examine demographic and economic trends to understand the patterns, scale, and complexity of urban poverty, income inequality, and rural–urban migration. Going beyond the space and poverty debate, they enlighten the readers about the quality of life questions, sustainability matters, and gender and generational roles and relations necessary to understand qualitative transformation and migrants’ prospects for a better future.

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.
