Book Description
The detailed analysis of current cropping areas in Africa presented here reveals significant climate sensitivities of cropland density and distribution across a variety of agro-ecosystems. Based on empirical climate-cropland relationships, cropland density responds positively to increases in precipitation in semi-arid and arid zones of the sub-tropics and warmer temperatures in higher elevations. As a result, marginal increases in seasonal precipitation lead to denser cropping areas in arid and semi-arid regions. Warmer temperatures, on the other hand, tend to decrease the probability of cropping in most parts of Africa (the opposite is true for increases in rainfall and decreases in temperatures relative to current conditions). Despite discrepancies and uncertainties in climate model output, the analysis suggests that cropland area in Africa is likely to decrease significantly in response to transient changes in climate. The continent is expected to have lost on average 4.1 percent of its cropland by 2039, and 18.4 percent is likely to have disappeared by the end of the century. In some regions of Africa the losses in cropland area are likely to occur at a much faster rate, with northern and eastern Africa losing up to 15 percent of their current cropland area within the next 30 years or so. Gains in cropland area in western and southern Africa due to projected increases in precipitation during the earlier portions of the century will be offset by losses later on. In conjunction with existing challenges in the agricultural sector in Africa, these findings demand sound policies to manage existing agricultural lands and the productivity of cropping systems.

Book Description
This book analyzes and elucidates the nature of predictable changes on the world's agricultural system caused by the so-called greenhouse effect. Its aim is to educate students at the undergraduate level about how the climatic factors affecting agriculture may be modified in the future, andwhat practical adaptations might be undertaken to prevent or overcome any possible adverse impacts on our ability to feed the world's population. The book draws on several complimentary disciplines, including atmospheric science, hydrology, soil science, crop physiology, and resource economics, andintegrates the relevant aspects of these fields.

Book Description
A major task of our time is to ensure adequate food supplies for the world's current population (now nearing 7 billion) in a sustainable way while protecting the vital functions and biological diversity of the global environment. The task of providing for a growing population is likely to be even more difficult in view of actual and potential changes in climatic conditions due to global warming, and as the population continues to grow. Current projections suggest that the world's temperatures will rise 1.8-4.0 by 2100 and population may reach 8 billion by the year 2025 and some 9 billion by mid-century, after which it may stabilize. This book addresses these critical issues by presenting the science needed not only to understand climate change effects on crops but also to adapt current agricultural systems, particularly in regard to genetics, to the changing conditions. Crop Adaptation to Climate Change covers a spectrum of issues related to both crops and climatic conditions. The first two sections provide a foundation on the factors involved in climate stress, assessing current climate change by region and covering crop physiological responses to these changes. The third and final section contains chapters focused on specific crops and the current research to improve their genetic adaptation to climate change. Written by an international team of authors, Crop Adaptation to Climate Change is a timely look at the potentially serious consequences of climate change for our global food supply, and is an essential resource for academics, researchers and professionals in the fields of crop science, agronomy, plant physiology and molecular biology; crop consultants and breeders; as well as climate and food scientists.

Book Description
Agricultural, botanical, and social scientists from the four quarters of the world address the impact of climate change on crop productivity, some approaches to adapt plants to both biotic and abiotic stresses, and measures to reduce greenhouse gases. They cover predictions of climate change within the context of agriculture, adapting to biotic and abiotic stresses through crop breeding, sustainable and resource-conserving technologies for adapting to and mitigating climate change, and new tools for enhancing crop adaptation to climate change. Specific topics include economic impacts of climate change on agriculture to 2030, breeding for adaptation to heat and drought stress, managing resident soil microbial community structure and function to suppress the development of soil-borne diseases, and applying geographical information systems (GIS) and crop simulation modeling in climate change research.

Book Description
The Anthropocene, the time of humans. Never has human influence on the functioning of the planet been greater or in more urgent need of mitigation. Climate change, the accelerated warming of the planet’s surface attributed to human activities, is now at the forefront of global politics. The agriculture sector not only contributes to climate change but also feels the severity of its effects, with the water, carbon and nitrogen cycles all subject to modification as a result. Crop production systems are each subject to different types of threat and levels of threat intensity. There is however significant potential to both adapt to and mitigate climate change within the agricultural sector and reduce these threats. Each solution must be implemented in a sustainable manner and tailored to individual regions and farming systems. This Special Issue evaluates a variety of potential climate change adaptation and mitigation techniques that account for this spatial variation, including modification to cropping systems, Climate-Smart Agriculture and the development and growth of novel crops and crop varieties.

Book Description
This book has comprehensive coverage and advances in agriculture for sustainable development and is expected to provide valuable sources for scholars and researchers, as well as serve as a guide book to the farmer’s community and development agencies. The book is organized into 18 chapters, which include advances in production technologies of crops e.g. rice, wheat, barley, maize, pearl millet, pulses and oilseeds; sugarcane; medicinal and aromatic plants; vegetable crops; fodder crops; resource conservation technologies; management of degraded and sodic lands; soil biodiversity; farm mechanization, etc. The text is illustrated with tables, figures and photographs to bring out the significant findings. The book provides cutting-edge scientific knowledge as well as solid background information that are accessible for those who have a strong interest in agricultural research and development and want to learn more on the challenges facing the global agricultural production systems. Note: T&F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka. This title is co-published with New India Publishing Agency.
