Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.
Tales of deforestation and desertification in North Africa have been told from the Roman period to the present. Such stories of environmental decline in the Maghreb are still recounted by experts and are widely accepted without question today. International organizations such as the United Nations frequently invoke these inaccurate stories to justify environmental conservation and development projects in the arid and semiarid lands in North Africa and around the Mediterranean basin. Recent research in arid lands ecology and new paleoecological evidence, however, do not support many claims of deforestation, overgrazing, and desertification in this region. Diana K. Davis’s pioneering analysi...
An argument that the perception of arid lands as wastelands is politically motivated and that these landscapes are variable, biodiverse ecosystems, whose inhabitants must be empowered. Deserts are commonly imagined as barren, defiled, worthless places, wastelands in need of development. This understanding has fueled extensive anti-desertification efforts—a multimillion-dollar global campaign driven by perceptions of a looming crisis. In this book, Diana Davis argues that estimates of desertification have been significantly exaggerated and that deserts and drylands—which constitute about 41% of the earth's landmass—are actually resilient and biodiverse environments in which a great many...
Qaidu (1236-1301), one of the great rebels in the history of the Mongol Empire, was the grandson of Ogedei, the son Genghis Khan had chosen to be his heir. This boof recounts the dynastic convolutions and power struggle leading up to his rebellion and subsequent events.
Perspectives on agroforestry. Prominence and importance of agroforestry in selected regions. Impact measurement and technology transfer. Research findings and proposals.
The description and analysis of the Mexican and other countries desertic plants from the point of view of their use in traditional medicine and their potential use in integrative medicine is the overall theme of this book. Aromatic and Medicinal Plants of Drylands and Deserts: Ecology, Ethnobiology and Potential Uses describes the historic use of drylands plants, botanical and geological classification, also describes the endemic plants used in traditional medicine, going through the most relevant aspects of biomedicine and integrative medicine. The chemical and bioactive compounds from desertic medicinal and aromatic plants and the analytic techniques to determine chemical and bioactive com...
