Description : Hundreds of millions of people still suffer from chronic hunger and food insecurity despite sufficient levels of global food production. The poor's inability to afford adequate diets remains the biggest constraint to solving hunger, but the dynamics of global food insecurity are complex and demand analysis that extends beyond the traditional domains of economics and agriculture. How do the policies used to promote food security in one country affect nutrition, food access, natural resources, and national security in other countries? How do the priorities and challenges of achieving food security change over time as countries develop economically? The Evolving Sphere of Food Security seeks to answer these two important questions and others by exploring the interconnections of food security to security of many kinds: energy, water, health, climate, the environment, and national security. Through personal stories of research in the field and policy advising at local and global scales, a multidisciplinary group of scholars provide readers with a real-world sense of the opportunities and challenges involved in alleviating food insecurity. In sub-Saharan Africa, for example, management of HIV/AIDS, the establishment of an equitable system of land property rights, and investment in solar-powered irrigation play an important role in improving food security---particularly in the face of global climate change. Meanwhile, food price spikes associated with the United States' biofuels policy continue to have spillover effects on the world's rural poor with implications for stability and national security. The Evolving Sphere of Food Security traces four key areas of the food security field: 1) the political economy of food and agriculture; 2) challenges for the poorest billion; 3) agriculture's dependence on resources and the environment; and 4) food in a national and international security context. This book connects these areas in a way that tells an integrated story about human lives, resource use, and the policy process.
Description : The present edited volume 'Neem - A Treatise' provides a comprehensive and authoritative account of this wonder tree - Neem (Azadirachta indica A. Juss). An excellent reference text, it offers a versatile and indepth account of occurrence, distribution, ethnobotany, uses in agroforestry, silviculture and social forestry, cultivation and improvement of neem, propagation by tissue culture, chemical constituents and their bioactivity against micro-flora and micro-fauna, disease, stored grain insect-pests, enhancing fertilizer use efficiency, neem in health and cosmetics, various therapeutic uses such as malaria and vector control, contraceptive, ancient veterinary medicines, uses of neem bark in dying cotton fabrics and steps for promoting neem and its cultivation. Hopefully, this book will be very useful for researchers of various disciplines such as botany, forestry, chemistry, toxicology, agrochemicals, soil science, agronomy, entomology, plant pathology, medical and veterinary science and to the environmental conscious farmers of developed and developing countries. The present book includes 37 chapters broadly divided in 8 sections contributed by eminent scientists working on different aspects of neem. An attempt has been made to present as many aspects as possible under the sections given below:
