Abstract The ecology of the arid and semi-arid regions of East Africa is essentially the ecology of subsistence pastoralism. Pastoralists and their herds are ubiquitous in the drier parts of East Africa. Pastoralists need these areas for their survival and, in tum, significantly affect them.

Experimental landfill caps for semi-arid and arid climates
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2005The United States EPA Subtitle D municipal solid waste landfill requirements specify that the permeability of a cap to a landfill be no greater than the permeability of the underliner. In recent years the concept of the evapotranspirative (ET) cap has been developed in which the cap is designed to store all rain infiltration and re-evapotranspire it ...

Plant Production in Arid and Semi-Arid Areas
1976The determination of phytomass and the assessment of actual and potential primary production of a natural ecosystem has become an important part of modern ecological research. In order to understand the functioning of an ecosystem, to analyse it, and to build valid models (see van Keulen et al., this volume Part 6:B), exact phytomass and production ...

Progress in Physical Geography: Earth and Environment, 1999
Geomorphologists working in the arid zone have continued to make a significant contribution to knowledge in the past year, producing a wide variety of high-quality papers. As reflected in the last three Progress Reports (Nash, 1999, 2000, 2001), there continues to be a high volume of publications, with over 200 articles reviewed here.

Vermicomposting in Arid and Semi-Arid Regions
Introduction Arid and semi-arid areas are marked by limited rainfall, elevated temperatures, and frequently degraded soils. These conditions pose significant challenges for sustainable agriculture, primarily due to inadequate soil fertility and water scarcity. Nonetheless, vermicomposting emerges as a viable method to enhance soil health and encourageopenaire +1 more source
