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.

The purpose of this report is to assess the current implementation of forest and landscape restoration (FLR) in Africa. It presents the context for FLR on the African continent, highlights major FLR initiatives, and provides an overview of FLR in Africa at the start of the UN Decade on Ecosystem Restoration (2021–2030). It identifies key challenges, opportunities, actors and processes, illustrated with some case studies. Data collection was both primary (interviews) and secondary (extensive desk research). The report contributes to tracking progress on the implementation of AFR100 and other FLR initiatives in Africa on the ground. It provides a baseline for the UN Decade on Ecosystem Restoration and is expected to be updated at regular intervals. The report is prepared under the jointly implemented regional technical cooperation programme by FAO Regional Office for Africa (RAF) and the African Union Development Agency-NEPAD (AUDA-NEPAD) “Support to the implementation and monitoring of the African Forest Landscape Restoration Initiative (AFR100)” and in close collaboration with AFR100 Management Team members and partners. It is also responding to the recommendation of the 22nd Session of FAO African Forestry and Wildlife Commission1, held in March 2020 in South Africa. The report is structured as follows: Chapter 1 introduces the importance of Africa’s forests and tree-based landscapes and to the challenges they and their people face, as well as the relevance of restoration and the global policy context. The next chapter presents an overview of FLR and restoration more generally. The third chapter provides a more detailed overview for Africa’s subregions of the current status of forests with examples of FLR initiatives (or other relevant ones that may not have the FLR label but are in fact aligned with FLR). Chapter 4 then reviews some key success factors for FLR in Africa. Chapter 5 presents opportunities going forward and remaining challenges. The last chapter is more forward-looking and speculative, highlighting potential priorities for FLR in the UN Decade on Ecosystem Restoration.

World Bank Technical Paper No. 370. Local land users and officials often have conflicting perceptions of and responses to land degradation issues. This causes problems for officials in diagnosing and addressing the issue and is a major constraint on the successful implementation of policies and projects to address land degradation. This study looks at the perception and response gap between officials and land users in the diagnosis and remedy of land degradation. It also examines the dynamics of the loss of soil fertility and low productivity at the village level. The study's findings will help shape investment programs to enhance land productivity in Sub-Saharan Africa.

Forest degradation as a result of logging, shifting cultivation, agriculture and urban development is a major issue throughout the tropics. It leads to loss in soil fertility, water resources and biodiversity, as well as contributes to climate change. Efforts are therefore required to try to minimize further degradation and restore tropical forests in a sustainable way. This is the first research-based book to examine this problem in East Africa. The specific focus is on the forests of Ethiopia, Tanzania and Uganda, but the lessons learned are shown to be applicable to neighbouring countries and others in the tropics. A wide range of forest types are covered, from dry Miombo forest and afromontane forests, to forest-savannah mosaics and wet forest types. Current management practices are assessed and examples of good practice presented. The role of local people is also emphasized. The authors describe improved management and restoration through silviculture, plantation forestry and agroforestry, leading to improvements in timber production, biodiversity conservation and the livelihoods of local people.

With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

The West African Sahel is the transition zone between the Saharadesert in the north of Africa and the more humid Sudanian zones in the south. Although diverse in many ways, the Sahelian countries have the common problem of a fragile agricultural sector. This predicament is mainly caused by low inherent soil fertility, limited and unpredictable rainfall, frequent droughts, and wind erosion that accelerates soil degradation and desertification, compounded by To assure food production in the future, means rapidly growing populations. of declining soil fertility and increasing must be found to offset the trends soil degradation through wind erosion. This is a challenge for agricultural research. Since 1985, the Special Research Program 308 'Adapted Farming in West Africa' at the UniversityofHohenheimin collaboration with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in Niger, has pursued the developmentof agricultural innovations for smallholder farmers in one of the most ecologically fragile regions of the world. The prevention of soil degradation, the restoration and maintenance of soil fertility, and the increase of land and labor productivity are key objectives of this multidisci plinary research program. From the beginning, a major focus of research has been wind erosion.
