A Sustainability Challenge


Book Description

The National Research Council's Science and Technology for Sustainability Program hosted two workshops in 2011 addressing the sustainability challenges associated with food security for all. The first workshop, Measuring Food Insecurity and Assessing the Sustainability of Global Food Systems, explored the availability and quality of commonly used indicators for food security and malnutrition; poverty; and natural resources and agricultural productivity. It was organized around the three broad dimensions of sustainable food security: (1) availability, (2) access, and (3) utilization. The workshop reviewed the existing data to encourage action and identify knowledge gaps. The second workshop, Exploring Sustainable Solutions for Increasing Global Food Supplies, focused specifically on assuring the availability of adequate food supplies. How can food production be increased to meet the needs of a population expected to reach over 9 billion by 2050? Workshop objectives included identifying the major challenges and opportunities associated with achieving sustainable food security and identifying needed policy, science, and governance interventions. Workshop participants discussed long term natural resource constraints, specifically water, land and forests, soils, biodiversity and fisheries. They also examined the role of knowledge, technology, modern production practices, and infrastructure in supporting expanded agricultural production and the significant risks to future productivity posed by climate change. This is a report of two workshops.




Climate Impacts on Agricultural and Natural Resource Sustainability in Africa


Book Description

This book discusses knowledge-based sustainable agro-ecological and natural resource management systems and best practices for sustained agricultural productivity and ecosystem resilience for better livelihoods under a changing climate. With a focus on agriculture in Africa, the book assesses innovative technologies for use on smallholder farms, and addresses some of the key Sustainable Development Goals to guide innovative responses and enhanced adaptation methods for coping with climate change. Contributions are based on 'Capacity Building for Managing Climate Change in Malawi' (CABMACC), a five-year program with an overall goal to improve livelihoods and food security through innovative responses and enhanced capacity of adaptation to climate change. Readers will discover more about sustainable crop production, climate smart agriculture, on-farm energy supply from biogas and the potential of soil carbon sequestration in crop-livestock systems.




Soil Management


Book Description

Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.







Sustainable Resource Management


Book Description

Sustainable Resource Management: Modern Approaches and Contexts presents the application of the current concept of sustainability to the management of natural resources, such as water, land, minerals and metals using theoretical field knowledge and illustrative real-world examples. Initially, the book defines sustainability, detailing its evolution and how it has been adapted to each of the contexts in which it is used. Furthermore, sustainability is made up of three main areas of science—environmental, social and economic—which are rarely considered together. This book is a complete reference guide to sustainability of natural resources for academics, researchers, practitioners and postgraduate-level students, and more. As sustainability is an interdisciplinary field, linked to most sciences, it is also of use to all fields of science that need to maintain sustainable practices and specific details on the methodologies and techniques needed for sustainable resource management. - Provides an integrated approach for modern tools, methodologies and indicators for sustainable resource management - Evaluates emerging trends and advanced approaches in sustainable resource management, detailing the most up-to-date research and management considerations - Describes advanced sustainable resource management technologies and presents case studies where applicable




Sustainable Intensification


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.




Systems Research for Agriculture


Book Description




Resources Use Efficiency in Agriculture


Book Description

Achieving zero hunger and food security is a top priority in the United Nations Development Goals (UNDGs). In an era characterized by high population growth and increasing pressure on agricultural systems, efficiency in the use of natural resources has become central to sustainable agricultural practices. Fundamentally speaking, eco-efficiency is about maximizing agricultural outputs, in terms of quantity and quality, using less land, water, nutrients, energy, labor, or capital. The concept of eco-efficiency involves both the ecological and economic aspects of sustainable agriculture. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape, as well as farmers’ economic needs. This book examines the latest eco-efficient practices used in agro-systems. Drawing upon research and examples from around the world, it offers an up-to-date overview, together with insights into directly applicable approaches for poly-cropping systems and landscape-scale management to improve the stability of agricultural production systems, helping achieve food security. The book will be of interest to educators, researchers, climate change scientists, capacity builders and policymakers alike. It can also be used as additional reading material for undergraduate and graduate courses on agriculture, forestry, soil science, and the environmental sciences.




Managing Biodiversity in Agricultural Ecosystems


Book Description

Describes how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. Includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels.
