African agriculture faces major challenges with growing population pressure and the impact of climate change. Until now food production overall has broadly kept pace with demand. To maintain this impressive achievement, production from the land needs to be intensified, soil fertility must be enhanced, forests and water resources must be conserved, and land use practices must be sustainable over the long term. This book shows what needs to be done, and points to how best to achieve this. The book starts with a brief guide to what plants and animals need to grow well, how farmers currently use the land, and the research that is being conducted on new agricultural technologies. A comparison is made of productivity on small and large farms, which demonstrates that, contrary to some suggestions, small farmers, properly serviced, can be as productive or even more productive than larger farms. Subsequent chapters discuss issues of land tenure, pastoralism, training, the importance of women farmers, access to finance, markets, value chains, and contract farming as a partnership between small-scale producers, processors and traders in agricultural products. The final section of the book discusses whether a new green revolution is feasible or desirable for Africa. The potential risks and benefits of dependence on purchased agrochemicals, genetically modified varieties, and multinational seed and chemical companies are examined. A series of twelve broad policy proposals for achieving a sustainable agriculture sector is presented for consideration. Fifteen case studies illustrate the issues discussed in the book. Most of the examples are from East Africa, particularly Tanzania, but the principles addressed are relevant across the African continent. Each chapter of the book includes references and suggestions for further reading, most of them freely available to anyone with internet access. A set of essay questions exploring the issues covered in each chapter is included, to provide practical help for students of agriculture and their teachers.

Population and income growth determine increasing demand for agricultural products, especially food products; and agricultural production requires land. This paper analyses historical trends in growth of agricultural production (total and per capita, at world level and for major regions) during the half century since 1961 to 2011, and the relative contributions to such growth coming from additional land and from increased land productivity, and summarises the latest studies on availability of extra suitable land. World production has been growing steadily ahead of population, causing a rising tendency in agricultural and food output per capita; such growth has been achieved with very little addition of extra land; land use for agriculture peaked around 1990 and has been stagnant or declining since; extra land contributed just about 5% of agricultural output growth from 1961 to 2011, and almost nothing in the latest decades. On the other hand, land suitable for rain-fed crop production that is not forested, not built-up, not otherwise protected, and not yet cropped, is quite abundant. However, projections of future agricultural growth, even under very conservative hypotheses, do not envisage much increase in the use of extra land. Available estimates show that agricultural Total Factor Productivity (TFP) is the dominant factor in agricultural growth, and that growth of agricultural TFP is accelerating. The world produces more than enough food relative to the needs of the world's population (though unequal access persists), and is very far from running out of land to sustain agricultural growth in the future, even assuming less progress in productivity in the coming decades.

A major challenge of the twenty-first century will be to ensure sufficient global food production to cope with the burgeoning world population. Soils, Land and Food is a short text aimed at undergraduates, graduates, agricultural scientists and policy makers which describes how the use of technology in soil management can increase and sustain agricultural production. The book leads the reader through the development of techniques of land management and discusses reasons why some agricultural projects have succeeded while others have failed. It shows how surveying and protecting soils before new land is brought into cultivation, raising soil fertility, increasing inputs and improving economic conditions can all help to increase food production. Particular emphasis is placed on the need for both economic change and technological intervention in developing countries where, in many cases, food production will need to more than double in the next fifty years.

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.

This book outlines a new paradigm, Sustainable Intensification of Crop Production (SICP), which aims to produce more from the same area of land by increasing efficiency, reducing waste, conserving resources, reducing negative impacts on the environment and enhancing the provision of ecosystem services. The use of ecologically based management strategies can increase the sustainability of agricultural production while reducing off-site consequences. The book also highlights the underlying principles and outlines some of the key management practices and technologies – such as minimum soil disturbance; permanent organic soil covers; species diversification; selection of suitable cultivars, planting time, age and spacing; balanced plant nutrition; agro-ecological pest management; efficient water management; careful management of farm machinery; and integrated crop-livestock production – required to implement SICP. The green revolution (by using high-yielding crop varieties, mono-cropping, fertilization, irrigation, and pesticides) has led to enormous gains in food production and improved world food security. In many countries, however, intensive crop production has had negative impacts on production, ecosystems and the larger environment, putting future productivity at risk. In order to meet the projected demands of a growing population expected to exceed 9 billion by 2050, farmers in the developing world must double food production, a challenge complicated by the effects of climate change and growing competition for land, water and energy. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities concerning sustainable intensification. The material can be used for teaching post-graduate courses, or as a useful reference guide for policy makers.

Due to many challenges (i.e. climate change, energy, water and land shortage, high demands on food, land grabbing, etc.), agriculture production potential is expected to be seriously affected; thus, increasing food insecurity and hunger in many already affected regions (especially in Africa). In this context, sustainable agriculture is highly recommended as an eco-system approach where soil, water, plants, environment and living organisms live in harmony. Innovative technologies and research should be developed to ensure sustainable agriculture and productivity using modern irrigation systems, improved varieties, improved soil quality, etc. In the meantime, the preservation of natural environment should be based on resource conservation technologies and best management practices. Sustainable Agricultural Development, not only raises the serious ethical and social issues underlying these huge environmental problems, but also aims at presenting successful experiences from all over the world in relation with sustainable farming, sustainable management of water and land resources, and innovative processes in livestock production. It also aims at providing inputs to decision making processes and encouraging the transfer of relevant know-how, technologies and expertise to different countries where similar agro-climatic conditions may exist; thus saving precious resources and promoting sustainable agricultural development as a relevant approach to tackle the food security challenge. Finally, this book focuses on the paradigmatic and policy dimensions and call for an innovative approach by analyzing the key themes in a complex and interrelated manner.

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.
