Book Description
Soils of South Africa is the first book in seventy years that provides a comprehensive account of South African soils. The book arranges more than seventy soil forms into fourteen groups and then provides, for each group: • maps showing their distribution and abundance throughout South Africa • descriptions of morphological, chemical and physical properties • a detailed account of classification and its correlation with international systems • a discussion of soil genesis which includes a review of relevant research papers • appraisal of soil quality from a land use perspective as well as for its ecological significance • illustrative examples of soil profiles with analytical data and accompanying interpretations. There is also a fascinating account of the special relationship that exists between South African animals and soil environments. Soils of South Africa should interest students and researchers in the earth, environmental and biological sciences, as well as environmental practitioners, farmers, foresters and civil engineers.

Book Description
World Bank Technical Paper No. 408. This report is a critical review of the technical, economic, and institutional constraints on improving soil fertility in Sub-Saharan Africa, and the actions recommended to address them. Action plans prepared for Ghana, Kenya, Malawi, and Mali examine the demand for and supply of mineral fertilizers, the exploitation of local mineral resources, the prevention of soil erosion and increasing soil-water retention, and soil fertility management using organic technologies and management practices.

Book Description
Thousands of years of poor farming and ranching practices—and, especially, modern industrial agriculture—have led to the loss of up to 80 percent of carbon from the world’s soils. That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet. In The Soil Will Save Us, journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for "our great green hope"—a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon—and potentially reverse global warming. As the granddaughter of farmers and the daughter of avid gardeners, Ohlson has long had an appreciation for the soil. A chance conversation with a local chef led her to the crossroads of science, farming, food, and environmentalism and the discovery of the only significant way to remove carbon dioxide from the air—an ecological approach that tends not only to plants and animals but also to the vast population of underground microorganisms that fix carbon in the soil. Ohlson introduces the visionaries—scientists, farmers, ranchers, and landscapers—who are figuring out in the lab and on the ground how to build healthy soil, which solves myriad problems: drought, erosion, air and water pollution, and food quality, as well as climate change. Her discoveries and vivid storytelling will revolutionize the way we think about our food, our landscapes, our plants, and our relationship to Earth.

Book Description
A powerful movement is happening in farming today—farmers are reconnecting with their roots to fight climate change. For one woman, that’s meant learning her tribe’s history to help bring back the buffalo. For another, it’s meant preserving forest purchased by her great-great-uncle, among the first wave of African Americans to buy land. Others are rejecting monoculture to grow corn, beans, and squash the way farmers in Mexico have done for centuries. Still others are rotating crops for the native cuisines of those who fled the “American wars” in Southeast Asia. In Healing Grounds, Liz Carlisle tells the stories of Indigenous, Black, Latinx, and Asian American farmers who are reviving their ancestors’ methods of growing food—techniques long suppressed by the industrial food system. These farmers are restoring native prairies, nurturing beneficial fungi, and enriching soil health. While feeding their communities and revitalizing cultural ties to land, they are steadily stitching ecosystems back together and repairing the natural carbon cycle. This, Carlisle shows, is the true regenerative agriculture – not merely a set of technical tricks for storing CO2 in the ground, but a holistic approach that values diversity in both plants and people. Cultivating this kind of regenerative farming will require reckoning with our nation’s agricultural history—a history marked by discrimination and displacement. And it will ultimately require dismantling power structures that have blocked many farmers of color from owning land or building wealth. The task is great, but so is its promise. By coming together to restore these farmlands, we can not only heal our planet, we can heal our communities and ourselves.

Book Description
This book provides a new inter-disciplinary look at the practice and policies of conservation in Africa. Bringing together social scientists, anthropologists and historians with biologists for the first time, the book sheds some light on the previously neglected but critically important social aspects of conservation thinking. To date conservation has been very much the domain of the biologist, but the current ecological crisis in Africa and the failure of orthodox conservation policies demand a radical new appraisal of conventional practices. This new approach to conservation, the book argues, cannot deal simply with the survival of species and habitats, for the future of African wildlife is intimately tied to the future of African rural communities. Conservation must form an integral part of future policies for human development. The book emphasises this urgent need for a complementary rather than a competitive approach. It covers a wide range of topics important to this new approach, from wildlife management to soil conservation and from the Cape in the nineteenth century to Ethiopia in the 1980s. It is essential reading for all those concerned about people and conservation in Africa.

Book Description
This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.
