Socioeconomic/household characteristics, agroecological heterogeneity, market access, and variety characteristics are used to empirically explain why households continue to cultivate traditional varieties of wheat in Turkey even though higher-yielding modern varieties exist. These determinants are then used to examine on-farm diversity outcomes and how the availability of modern varieties is affecting the in situ conservation of crop genetic resources from landraces. Socioeconomic/household characteristics, agroecological heterogeneity, and market access are all found to jointly influence households' decisions to cultivate landraces and to affect on-farm diversity outcomes. Empirical estimation shows that variety characteristics do not jointly affect the probability that households plant landraces, nor do they affect on-farm diversity levels. Policy recommendations and ideas for future research are provided.

Based on twenty years of global research, this is the first comprehensive reference on crop genetic diversity as it is maintained on farmland around the world. Showcasing the findings of seven experts representing the field of ecology, crop breeding, genetics, anthropology, economics, and policy, this invaluable resource places farmer-managed crop biodiversity squarely in the center of the science needed to feed the world and restore health to our productive landscapes. It will prove to be an essential tool in the training of agricultural and environmental scientists seeking the solutions necessary to ensure healthy, resilient ecosystems for future generations.--

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.

Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.

This book examines the challenges faced by farmers trying to maintain crop biodiversity in developing and transitional economies. Using a collection of empirical case studies of farmers and crop scientists across a range of agricultural economies and income levels, it presents economic tools and methods for valuing and managing crop biodiversity. It discusses the economic benefits of crop biodiversity for farmers and suggests ways in which crop biodiversity can be supported by national policies. The book provides an indispensable 'tool kit' for all those concerned with the development of strategies to facilitate sustainable management and conservation of crop genetic diversity for future generations.

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
