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.

Precision farming involves soil fertility and crop growth monitoring, electronic equipment, remote sensing, global information and positioning systems, computer models, decision support systems, variable-rate technology, and accurate recordkeeping. This book on precision techniques provides valuable information on instrumentation and methodology. It discusses the impact of precision techniques on soil fertility, nutrient dynamics, and crop productivity and highlights the application of GPS techniques to regulate fertilizer supply based on soil nutrient distribution and yield goals set by farmers. The book considers advances and examples from different agroecosystems from all continents.

This publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory approaches for soil productivity improvement. The need for action and collaborative efforts of all stakeholders, within the framework of ongoing initiatives, are emphasized. It is hoped that this document will contribute to increase awareness of senior specialists and policy-makers about the problems and alternative solutions towards enhanced and sustained soil productivity.

Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.

Climate change is one of the major challenges of modern times. Its impacts are manifold and vary from sea level rise (especially relevant to those living in coastal areas), to the increased frequency of extreme events such as cyclones and storm surges, which not only poses problems to property and infrastructure, but also to human health. Climate change is also associated with damages to the physical and natural environment, as well as to biodiversity. According to the 5th Assessment Report produced by the Inter-Governmental Panel on Climate Change (IPCC), many geographical regions across the world are moderately or highly vulnerable to climate change, whose impacts may be further exacerbated by other human-induced pressures. The above state of affairs illustrates the need for a better and more holistic understanding of how climate change affects countries and regions on the one hand, but also on how the many problems it causes may be managed on the other, vis-a-vis a better ability to adapt. There is also a perceived need to showcase successful examples of how to duly address and manage the many social, economic and political problems posed by climate change around the world, in order to replicate and even upscale the successful ones. It is against this background that the Handbook of Climate Change Management has been produced. It contains papers prepared by scholars, social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects, and working with communities across all geographical regions. The Handbook focuses on "Research, Leadership, Transformation," meaning that it serves the purpose of showcasing the role these key areas play in respect of applied research, field projects and best practices to foster climate change adaptation worldwide.

Soil fertility is the backbone of agricultural systems and plays a key role in determining food quantity and quality. In recent decades, soil fertility has decreased due to indiscriminate use of agrochemicals, and nations around the globe are now facing the challenge of increasing food production while sustainably maintaining soil fertility. Written by leading international scientists in the field, this book explores soil fertility management strategies, including agronomic, microbiological and soil-science based strategies. Highlighting the practices that can be incorporated into organic farming and discussing recent advances, it is a valuable resource for researchers wanting to broaden their vision and the scope of their investigations.

It is becoming more relevant to explore soil biological processes in terms of their contribution to soil fertility. This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It highlights the enormous diversity of life in soil and the resulting effects that management of land can have on the contribution of this diverse community to soil fertility in an agricultural context.

This study examines the current and potential role of economics in soil productivity in sub-Saharan Africa. After examining the status of soil productivity and the contribution of conventional economic analyses, it considers more innovative approaches that enable economics to play a greater role in the planning and evaluation of soil productivity, enhancing measures at farm, national and global level. In the past economics has tended to focus on one factor at a time but many factors affect soil productivity. Decisions, policies and their impact call for a more integrative, participatory analytical approaches capable of weighing various aspects simultaneously. This study highlights how economics can respond to this challenge through the a[application of fresh concepts (e.g. natural capital) and specific techniques (e.g. multi-criteria analysis, green accounting).
