Book Description
This book addressed the pressing challenges of climate change, land scarcity, and food security, offering a comprehensive synthesis of research on using, managing, and reclaiming marginal lands in Africa. Unfavourable climatic conditions and rapid population growth intensify competition for land, putting pressure on traditional agricultural soils thus necessitating a transition towards underutilized marginal lands. Reclaiming these damaged and undervalued areas through various technologies presents a promising path not only to food independence but also to second-generation biofuel feedstock production, utilizing excess biomass from these revived lands. While recent years have seen increased focus on restoring degraded lands, a crucial gap remains i.e. a unified knowledge base detailing the efficacy of various reclamation technologies. This book fills that void, empowering farmers and policymakers with the insights they need to make informed decisions, mobilize resources effectively, and ultimately help Africa meet its projected 60% food demand increase.

Book Description
Soil degradation is a widespread problem in Africa resulting in decreased agricultural productivity while demand for food continues to increase. Degradation is caused by accelerated erosion, acidification, contamination, depletion of soil organic matter and plant nutrients, and salinization. The major cause of soil degradation in Africa is uncontrolled and excessive grazing in the savanna regions followed by deforestation and the use of inappropriate and extractive farming practices. Perpetual neglect of the health of soils in Africa can exacerbate the already serious problems of food and nutritional insecurity and environmental degradation. Food and nutritional security of the growing population of Africa can only be achieved if degraded soils are restored and soils of agroecosystems are managed prudently and sustainably. Ignoring soils and taking the fragile, finite and precious soil resources for granted is the principal cause of poverty, hunger, and environmental degradation. The downward spiral must be reversed through soil restoration measures based on translating science into action. This book describes the soils of Africa, processes of soil degradation, extent and severity of soil degradation, and the impacts of degradation processes on food and nutritional security. Features: Explores the extent and severity of soil degradation in Africa Analyzes the cause–effect relationship between anthropogenic activities and soil degradation Reviews processes of soil degradation in Africa including erosion, salinization, nutrient depletion, and decline of soil organic matter Addresses the effect of climate change on soil degradation in Africa. Explains how soil degradation causes food and nutritional insecurity Part of the Advances in Soil Sciences series, this volume is specifically devoted to the processes and factors that cause soil degradation and the challenges and potential for remediation and restoration of soil health in Africa.

Book Description
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.

Book Description
This book provides a synthesis of current agricultural research in Africa with the aim of presenting evidence based information that can be directly applied into improving the African smallholder farmers’ food security. It presents positive scientific research that has been undertaken in Africa, in simpler terms, thus driving the research for development agenda contributing to the attainment of SDG 2. Numerous research that targets resource poor African smallholder farmers has been published, yet the region faces very low productivity levels. This lack of translation from research to food security and increased agricultural incomes is due to the poor uptake of scientific research by farmers, which is partly due to poor presentation of this body of knowledge into simpler forms that extension workers and farmers can directly adopt. Therefore, this book offers research information in an easy, digestible and application oriented style, so as to enable transformation of the African agricultural sector by effectively driving agricultural productivity in Africa. This book is of interest to African extension workers, who will translate the simplified knowledge into lessons that can be useful to smallholder farmers. The book is also beneficial for policy makers as well as academics, researchers and other science based professionals.

Book Description
Deforestation, soil erosion, desertification, air and water pollution, loss of wildlife habitat, and declining biodiversity are interrelated manifestations of a growing environmental crisis in North Africa that has received relatively little attention from government policymakers and is poorly understood by North African peoples, the international development community, and scholars. In this book a multidisciplinary group of scholars explores the broad range of human activities causing the deterioration of North Africa’s fragile environment, including population pressure and poverty, rapid urbanization, intense competition for land and water, and mismanagement of natural resources. The contributors examine in particular the conflict between economic development and environmental sustainability. They analyze the historical roots of current environmental problems, the underlying socioeconomic causes, potential solutions, and differences in environmental policies among various countries. This is an insightful portrait of a developing region attempting to reconcile traditional methods of land use with growing demands for resources, the exigencies of economic development, and the limitations of its natural resource base.

Book Description
The 'Gender in Agriculture Sourcebook' provides an up-to-date understanding of gender issues and a rich compilation of compelling evidence of good practices and lessons learned to guide practitioners in integrating gender dimensions into agricultural projects and programs. It is serves as a tool for: guidance; showcasing key principles in integrating gender into projects; stimulating the imagination of practitioners to apply lessons learned, experiences, and innovations to the design of future support and investment in the agriculture sector. The Sourcebook draws on a wide range of experience from World Bank, Food and Agriculture Organization (FAO), International Fund for Agricultural Development (IFAD), and other donor agencies, governments, institutions, and groups active in agricultural development. The Sourcebook looks at: access to and control of assets; access to markets, information and organization; and capacity to manage risk and vulnerability through a gender lens. There are 16 modules covering themes of cross-cutting importance for agriculture with strong gender dimensions (Policy, Public Administration and Governance; Agricultural Innovation and Education; Food Security; Markets; Rural Finance; Rural Infrastructure; Water; Land; Labor; Natural Resource Management; and Disaster and Post-Conflict Management) and specific subsectors in agriculture (Crops, Livestock, Forestry, and Fisheries). A separate module on Monitoring and Evaluation is included, responding to the need to track implementation and development impact. Each module contains three different sub-units: (1) A Module Overview gives a broad introduction to the topic and provides a summary of major development issues in the sector and rationale of looking at gender dimension; (2) Thematic Notes provide a brief and technically sound guide in gender integration in selected themes with lessons learned, guidelines, checklists, organizing principles, key questions, and key performance indicators; and (3) Innovative Activity Profiles describe the design and innovative features of recent and exciting projects and activities that have been implemented or are ongoing.

Book Description
This book introduces readers to the age of intra-African migration, a period from the mid-19th century onward in which the center of gravity of African migration moved decisively inward. Most books tend to zoom in on Africa’s external migration during the earlier intercontinental slave trades and the more recent outmigration to the Global North, but this book argues that migration within the continent has been far more central to the lives of Africans over the course of the last two centuries. The book demonstrates that only by taking a broad historical and continent-wide perspective can we understand the distinctions between the more immediate drivers of migration and deeper patterns of change over time. During the 19th century Africa’s external slave trades gradually declined, whilst Africa’s expanding commodity export sectors drew in domestic labor. This led to an era of heightened mobility within the region, marked by rapidly rising and vanishing migratory flows, increasingly diversified landscapes of migration systems, and profound long-term shifts in the wider patterns of migration. This era of inward-focused mobility reduced with a resurgence of outmigration after 1960, when Africans became more deliberate in search of extra-continental destinations, with new diaspora communities emerging specifically in the Global North. Broad ranging in its temporal, spatial, and thematic coverage, this book provides students and researchers with the perfect introduction to age of intra-African migration.

Book Description
This book is a state-of-the-art compilation of the latest information on ecosystem services of agroforestry. The last two decades have seen a surge in literature on the ecosystem services of sustainable agriculture practices, including that of agroforestry; however, compilation and synthesis of such information from agroforestry have been limited. This book fills that void by bringing in a number of experts from around the world. In addition to presenting the multiple dimensions of ecosystem services provided by major agroforestry practices, the book also offers case studies from both tropical and temperate regions of the world. Information from this book can be used to design land management practices for climate change mitigation, ecosystem benefits, agricultural productivity and sustainability, and for survival and profitability of family farms and to conserve biodiversity. While synthesizing information of the biophysical aspects of ecosystem services, the book also outlines the socioeconomic and policy dimensions, including appropriate incentive models to enhance adoption of agroforestry so that society at large can enjoy these important benefits
