Book Description
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.

Book Description
This publication reports on current work in progress to raise the agricultural productivity of a wide range of crops, in eco-friendly ways and in a number of countries around the world, using an agroecological methodology called the System of Crop Intensification (SCI). Through a shift in plant management, SCI allows farmers to increase their production while simultaneously reducing purchased inputs, building soil health, reducing water use, and making plants more resilient to climate change-induced stress.

Book Description
Soil Health and Intensification of Agroecosystems examines the climate, environmental, and human effects on agroecosystems and how the existing paradigms must be revised in order to establish sustainable production. The increased demand for food and fuel exerts tremendous stress on all aspects of natural resources and the environment to satisfy an ever increasing world population, which includes the use of agriculture products for energy and other uses in addition to human and animal food. The book presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate. The book explores the introduction of sustainable agroecosystems that promote biodiversity, sustain soil health, and enhance food production as ways to help mitigate some of these adverse effects. New agroecosystems will help define a resilient system that can potentially absorb some of the extreme shifts in climate. Changing the existing cropping system paradigm to utilize natural system attributes by promoting biodiversity within production agricultural systems, such as the integration of polycultures, will also enhance ecological resiliency and will likely increase carbon sequestration. - Focuses on the intensification and integration of agroecosystem and soil resiliency by presenting suggested modifications of the current cropping system paradigm - Examines climate, environment, and human effects on agroecosystems - Explores in depth the wide range of intercalated soil and plant interactions as they influence soil sustainability and, in particular, soil quality - Presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate

Book Description
Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems and institutional innovation. Much of the work represents outputs of the three CGIAR Research Programs on Integrated Systems for the Humid Tropics, Aquatic Agricultural Systems and Dryland Systems. The chapters are based around four themes: the conceptual underpinnings of systems research; sustainable intensification in practice; integrating nutrition, gender and equity in research for improved livelihoods; and systems and institutional innovation. While most of the case studies are from countries and agro-ecological zones in Africa, there are also some from Latin America, Southeast Asia and the Pacific.

Book Description
Sustainable intensification (SI) has emerged in recent years as a powerful new conceptualisation of agricultural sustainability and has been widely adopted in policy circles and debates. It is defined as a process or system where yields are increased without adverse environmental impact and without the cultivation of more land. Co-written by Jules Pretty, one of the pioneers of the concept and internationally known and respected authority on sustainable agriculture, this book sets out current thinking and debates around sustainable agriculture and intensification. It recognises that world population is increasing rapidly, so that yields must increase on finite land and other resources to maintain food security. It provides the first widely accessible overview of the concept of SI as an innovative approach to agriculture and as a key element in the transition to a green economy. It presents evidence from around the world to show how various innovations are improving yields, resilience and farm incomes, particularly for ‘resource constrained’ smallholders in developing countries, but also in the developed world. It shows how SI is a fundamental departure from previous models of agricultural intensification. It also highlights the particular role and potential of small-scale farmers and the fundamental importance of social and human capital in designing and spreading effective innovations.

Book Description
The System of Rice Intensification, known as SRI, is a management strategy for crop improvement. Its ideas, insights and practices are based on scientifically validated knowledge for increasing the production of not only irrigated rice but of other crops as well. SRI represents a paradigm shift in agricultural thinking and practice toward agroecological farming that can be used by even the poorest smallholding farmers in ecologically fragile regions of the world to achieve food security in the face of the climate-change challenges ahead. When the author Norman Uphoff first learned about SRI in Madagascar in 1993, this production system which offered higher yields with reduced inputs seemed implausible to him. But the professor put aside his skepticism after seeing farmers who had been getting rice yields of just two tons per hectare produce four times more rice-for three years in a row-on their very poor soils, not changing their varieties or relying on agrochemical inputs, and using less water. Now, he's helping to disseminate this dramatically effective methodology with this accessible, easy-to-use sourcebook. It offers explanations, research references, vivid pictures, and concrete examples of the award-winning SRI methodology to anyone interested in the development of practicable sustainable food systems. Now, he's helping to disseminate this revolutionary methodology with this accessible, easy-to-use primer. It offers explanations, resources, and concrete examples of the award-winning SRI to anyone interested in the development of practicable sustainable food systems.

Book Description
Explore an in-depth and insightful collection of resources discussing various aspects of root structure and function in intensive agricultural systems The Root Systems in Sustainable Agricultural Intensification delivers a comprehensive treatment of state-of-the-art concepts in the theoretical and practical aspects of agricultural management to enhance root system architecture and function. The book emphasizes the agricultural measures that enhance root capacity to develop and function under a range of water and nutrient regimes to maximize food, feed, and fibre production, as well as minimize undesirable water and nutrient losses to the environment. This reference includes resources that discuss a variety of soil, plant, agronomy, farming system, breeding, molecular and modelling aspects to the subject. It also discusses strategies and mechanisms that underpin increased water- and nutrient-use efficiency and combines consideration of natural and agricultural systems to show the continuity of traits and mechanisms. Finally, the book explores issues related to the global economy as well as widespread social issues that arise from, or are underpinned by, agricultural intensification. Readers will also benefit from the inclusion of: A thorough introduction to sustainable intensification, including its meaning, the need for the technology, components, and the role of root systems Exploration of the dynamics of root systems in crop and pasture genotypes over the last 100 years Discussion of the interplay between root structure and function with soil microbiome in enhancing efficiency of nitrogen and phosphorus acquisition Evaluation of water uptake in drying soil, including balancing supply and demand Perfect for agronomists, horticulturalists, plant and soil scientists, breeders, and soil microbiologists, The Root Systems in Sustainable Agricultural Intensification will also earn a place in the libraries of advanced undergraduate and postgraduate students in this field who seek a one-stop reference in the area of root structure and function.

Book Description
From climate change to farming systems to genetic modification of organisms, Crop Physiology, Second Edition provides a practical tool for understanding the relationships and challenges of successful cropping. With a focus on genetic improvement and agronomy, this book addresses the challenges of environmentally sound production of bulk and quality food, fodder, fiber, and energy which are of ongoing international concern. The second edition of Crop Physiology continues to provide a unique analysis of these topics while reflecting important changes and advances in the relevant science and implementation systems. Contemporary agriculture confronts the challenge of increasing demand in terms of quantitative and qualitative production targets. These targets have to be achieved against the background of soil and water scarcity, worldwide and regional shifts in the patterns of land use driven by both climate change and the need to develop crop-based sources of energy, and the environmental and social aspects of agricultural sustainability. - Provides a view of crop physiology as an active source of methods, theories, ideas, and tools for application in genetic improvement and agronomy - Written by leading scientists from around the world - Combines environment-specific cropping systems and general principles of crop science to appeal to advanced students, and scientists in agriculture-related disciplines, from molecular sciences to natural resources management
