Global agriculture is now at the crossroads. The Green Revolution of the last century is losing momentum. Rates of growth in food production are now declining, with land and water resources becoming scarcer, while world population continues to grow. We need to continue to identify and share the knowledge that will support successful and sustainable
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.
This book includes twenty-one comprehensive chapters addressing various soil and crop management issues, including modern techniques in enhancing crop production in the era of climate change. There are a few case studies and experimental evidence about these production systems in specific locations. Particular focus is provided on the state-of-the-art of biotechnology, nanotechnology, and precision agriculture, as well as many other recent approaches in ensuring sustainable crop production. This book is useful for undergraduate and graduate students, teachers, and researchers, particularly in the fields of crop science, soil science, and agronomy.
Interest is growing in sustainable agriculture, which involves the use of productive and profitable farming practices that take advantage of natural biological processes to conserve resources, reduce inputs, protect the environment, and enhance public health. Continuing research is helping to demonstrate the ways that many factorsâ€"economics, biology, policy, and traditionâ€"interact in sustainable agriculture systems. This book contains the proceedings of a workshop on the findings of a broad range of research projects funded by the U.S. Department of Agriculture. The areas of study, such as integrated pest management, alternative cropping and tillage systems, and comparisons with more conventional approaches, are essential to developing and adopting profitable and sustainable farming systems.
Agricultural Systems, Second Edition, is a comprehensive text for developing sustainable farming systems. It presents a synthetic overview of the emerging area of agroecology applications to transforming farming systems and supporting rural innovation, with particular emphasis on how research can be harnessed for sustainable agriculture. The inclusion of research theory and examples using the principles of cropping system design allows students to gain a unique understanding of the technical, biological, ecological, economic and sociological aspects of farming systems science for rural livelihoods. This book explores topics such as: re-inventing farming systems; principles and practice of agroecology; agricultural change and low-input technology; ecologically-based nutrient management; participatory breeding for developing improved and relevant crops; participatory livestock research for development; gender and agrarian inequality at the local scale; the nature of agricultural innovation; and outreach to support rural innovation. The extensive coverage of subjects is complemented with integrated references and a companion website, making this book essential reading for courses in international agricultural systems and management, sustainable agricultural management, and cropping systems. This book will be a valuable resource for students of agricultural science, environmental engineering, and rural planning; researchers and scientists in agricultural development agencies; and practitioners of agricultural development in government extension programs, development agencies, and NGOs. - Provides students with an enhanced understanding of how research can be harnessed for sustainable agriculture - Incorporates social, biological, chemical, and geographical aspects important to agroecology - Addresses social and development issues related to farming systems
This book surveys state-of-the-art and prospective practices, methods and technologies in agri-food and forestry sectors to document the potential measurable improvements in areas of environmental management, food security, economic growth, social cohesion and human health at the local and global scale. With a focus on the ecosystems-resources-climate-food-health nexus as a framework towards achieving the UN Sustainable Development Goals applicable in these sectors, the book offers a portfolio of guidelines and standards that assesses the affordability, potential profitability and possible unintended consequences of interventions. The areas of intervention covered in the study include global and local forest resources management, safe wastewater reuse for irrigation, sustainable crop and plant protection (e.g. biopesticides, bioherbicides), carbon sequestration and emission reduction strategies, and safe processing methods for food and food waste (e.g. sustainable food preservatives and healthier food). The book is primarily intended for academics, professionals, and policymakers. The professional audience, including enterprises in the forestry, farming, food processing, healthcare and waste management sectors, will take advantage of the updated knowledge basis concerning the innovations in the respective practices, methods and technologies, including their feasibility, affordability and profitability, and policymakers will find useful the comprehensive review of these innovations which could be strategically promoted and deployed in the next decade, with the aim of achieving the UN Sustainable Development Goals.

This annual report monitors and evaluates agricultural policies in 54 countries, including the 38 OECD countries, the five non‐OECD EU Member States, and 11 emerging economies. It finds that despite some modest declines in recent years, support to agriculture has remained close to recent historical highs. While changes in support have been limited, agricultural policies have been both reactive and proactive, boosting the sector’s capacity to respond to current challenges while aiming to ensure that food systems are fit for purpose as future conditions evolve. This year’s report focuses on policies fostering sustainable productivity growth in agriculture. Governments are applying a large variety of approaches to improve productivity while preserving natural resources and reducing agricultural greenhouse gas emissions. The report notes, however, that clearly defined targets related to sustainable productivity growth and measurable indicators of progress are important to ensure that policies achieve their stated objectives. The report also notes that making more effective use of producer support to promote innovation and environmental sustainability on the farm, and refocusing overall support towards targeted R&D, can better leverage public spending to deliver public goods and sustainable productivity growth. In line with the 2022 OECD Agriculture Ministerial Declaration, the report identifies a seven-point policy agenda for making agriculture more sustainable, productive and resilient, and for improving the effectiveness and efficiency of agricultural support and markets.
