FAO’s best-selling 2011 publication, Save and Grow, proposed a new paradigm of agriculture, one that is both highly productive and environmentally sustainable. This new book looks at the application of “Save and Grow” practices and technologies to production of the world’s key food security crops – maize, rice and wheat. With examples drawn from developing countries worldwide, it shows how eco-friendly farming systems are helping smallholder producers to boost cereal yields, improve their incomes and livelihoods, conserve natural resources, reduce negative impacts on the environment, and build resilience to climate change. The book will be a valuable reference for policymakers and development practitioners guiding the transition to sustainable food and agriculture.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

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

In this important new work, Howard T. Odum, widely acknowledged as the father of systems ecology, lucidly explains his concept of emergy, a measure of real wealth that provides a rational, science-based method of evaluating commodities, services, and environmental goods. Using specific real-world examples, Dr. Odum clearly demonstrates the revolutionary role of emergy in environmental management and policy making. Environmental Accounting: Emergy and Environmental Decision Making offers environmental professionals—policymakers, managers, ecologists, planners, developers, and activists—a systematic approach to environmental and economic valuation that will eliminate much of the rancor and adversarial decision making that often plagues environmental issues. Specifically, this book: Describes the theoretical basis, calculation procedures, and applications of emergy Introduces the concept of "transformity," the ratio of emergy (work put into a product) and energy (value received from the product) Provides formulas for emergy calculations, procedures for making an emergy evaluation table, and parameters for updating evaluations Demonstrates the use of emergy to evaluate environments, minerals, waters, primary energy sources, economic developments, and international trade Compares the emergy approach to environmental evaluation with others Environmental Accounting: Emergy and Environmental Decision Making will help environmental decision makers and the society they serve maximize economic vitality with less trial and error, innovate with fewer failures, and adapt to change more rapidly. It provides the tools they need to arrive at the best policies in resource management, economics, and the environment. Balancing the economy and the environment— from the father of systems ecology Increasing economic dependence on diminishing natural resources has sparked a highly charged debate over the use and fate of the world environment. Environmental Accounting: Emergy and Environmental Decision Making presents a unique method of environmental management based on maximizing real wealth, the whole economy, and the public benefit. Renowned ecologist Howard T. Odum introduces the concept of emergy to provide a rational alternative to the tug-of-war over the world's most vital assets. Emergy measures the energy put into making a product and is the cornerstone of Odum's revolutionary text. This timely and important book offers key insights into: Determining the real value of a product or service Transformity, or the relationship between emergy (input) and energy (output) Stored wealth, available energy, and the final product Balancing economic and environmental needs Environmental Accounting: Emergy and Environmental Decision Making will help economists, ecologists, policymakers, and planners make more responsible, informed decisions to sustain economic and environmental development.
