Book Description
"Grasses are very important features of the landscape and occur to a greater or lesser extent in all of the vegetation types of southern African. The importance of good grazing grasses for both wild and domesticated animals is well known. Some species are indicators of good or bad veld management and are useful to farmers and conservators. Crop farmers have to deal with undesirable grasses in their fields and the custodians of our indigenous vegetation need to correctly identify any alien invaders. This identification guide relies primarily on the use of keys and descriptive information to aid the user in identifying a grass species. It contains some of the best information needed to identify southern African grasses. Keys to grass genera and species are provided, and in some instances also keys to easily confused taxa. For each species, a combination of useful characters is provided, and where applicable, line drawings of the spikelet or parts thereof accompany the identification keys. Species descriptions and distribution maps are hugely important and add to the identification of grasses."--Back cover.

Book Description
Grasslands are of vital significance globally by covering more than one-quarter of the earth’s surface. They are known by a variety of names, such as prairies, pampas, steppes, savannas, and so on, and provide feed to animals as well as serve as biodiversity reserves and catchment areas. Under the changing climate scenario, they can potentially serve as carbon sinks, which might alleviate the adverse effects of greenhouse gas emissions. This book provides fundamental knowledge of underutilized grasses of economic significance as well as discusses advancements in grasslands management for boosting their bio-productivity. There is a particular focus on state-of-the-art strategies for the restoration and conservation of grasslands in the era of changing climate.

Book Description
Scenes of starvation have drawn the world's attention to Africa's agricultural and environmental crisis. Some observers question whether this continent can ever hope to feed its growing population. Yet there is an overlooked food resource in sub-Saharan Africa that has vast potential: native food plants. When experts were asked to nominate African food plants for inclusion in a new book, a list of 30 species grew quickly to hundreds. All in all, Africa has more than 2,000 native grains and fruitsâ€""lost" species due for rediscovery and exploitation. This volume focuses on native cereals, including: African rice, reserved until recently as a luxury food for religious rituals. Finger millet, neglected internationally although it is a staple for millions. Fonio (acha), probably the oldest African cereal and sometimes called "hungry rice." Pearl millet, a widely used grain that still holds great untapped potential. Sorghum, with prospects for making the twenty-first century the "century of sorghum." Tef, in many ways ideal but only now enjoying budding commercial production. Other cultivated and wild grains. This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains. Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source. The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production. Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains. This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.

Book Description
As part of a global effort to identify those areas where conservation measures are needed most urgently, World Wildlife Fund has assembled teams of scientists to conduct ecological assessments of all five continents. Terrestrial Ecoregions of Africa and Madagascar is the latest contribution, presenting in a single volume the first comprehensive assessment of biodiversity patterns, threats to biodiversity, and resulting conservation priorities across the African continent and its islands. Looking at biodiversity and threats in terms of biological units rather than political units, the book offers a comprehensive examination of African biodiversity across all biomes and multiple taxonomic groups. In addition to the seven main chapters, the book includes twenty essays by regional experts that provide more depth on key issues, as well as nine detailed appendixes that present summary data used in the analyses, specific analytical methodologies, and a thorough text description for each of Africa's 119 terrestrial ecoregions. Terrestrial Ecoregions of Africa and Madagascar provides a blueprint for conservation action and represents an unparalleled guide for investments and activities of conservation agencies and donor organizations.
