Climate Change and Food Security with Emphasis on Wheat


Book Description

Climate Change and Food Security with Emphasis on Wheat is the first book to present the full scope of research in wheat improvement, revealing the correlations to global issues including climate change and global warming which contribute to food security issues. Wheat plays a key role in the health of the global economy. As the world population continuously increases, economies modernize, and incomes rise, wheat production will have to increase dramatically to secure it as a reliable and sustainable food source. Since covering more land area with wheat crops is not a sustainable option, future wheat crops must have consistently higher yields and be able to resist and/or tolerate biotic and abiotic stresses that result from climate change. Addressing the biophysical and socioeconomic constraints of producing high-yielding, disease-resistant, and good quality wheat, this book will aid in research efforts to increase and stabilize wheat production worldwide. Written by an international team of experts, Climate Change and Food Security with Emphasis on Wheat is an excellent resource for academics, researchers, and students interested in wheat and grain research, especially as it is relevant to food security. - Covers a wide range of disciplines, including plant breeding, genetics, agronomy, physiology, pathology, quantitative genetics and genomics, biotechnology and gene editing - Explores the effect of climate change on biotic stresses (stripe rust, stem rust, leaf rust, Karnal bunt, spot blotch) on wheat production and utilization of biotechnology - Focuses on whole genome sequencing and next-generation sequencing technologies to improve wheat quality and address the issue of malnutrition in developing world




Agricultural Technology


Book Description

Major complex problems confront agricultural policy analysts and development specialists regarding the broad issue of 'agricultural technology.' These topics are reviewed in this volume which consists of 37 chapters, developed from papers presented at a conference held at Airlie House, Virginia, near Washington DC. The authors include leading international authorities from the academic sector, World Bank and agricultural research centers. The chapters are grouped into six parts. The first introductory part is followed by investment as the focus of Part II. In Part III a variety of conceptual and practical issues involved in the transfer of agricultural technology is considered. Part IV includes discussions of concrete technical matters ranging for example from the general to the specific, from plant to animal, and from soil management to irrigation engineering. Emphasis moves from the specifically technological to wider policy issues in Part V and this latter thrust is carried through into the final summarizing section.




An empirical examination of the dynamics of varietal turnover in Indian wheat


Book Description

This paper addresses the challenge of increasing the rate of varietal turnover to prevent depreciation of improved cultivars over time. It examines the supply of and demand for improved cultivars of wheat in India to illustrate this challenge in a unique manner, combining national-level data on breeder seed production with primary data on cultivar adoption. The analyses show that the rate of varietal turnover for wheat has slowed in India from an average of 9-10 years a decade ago to 13-14 years in 2010. By focusing on a sample of farmers and villages in Haryana, where seed and information networks are relatively well developed, the study finds that wheat farmers still prefer cultivars that were released 9-10 years ago.
