Cattle numbers, biomass, productivity and land degradation in the commercial farming sector of Namibia, 1915‐95

As part of a natural resource accounting project undertaken in Namibia, livestock accounts have been drawn up and are being used to analyse the relationship between numbers of livestock, rainfall, land degradation, and economic and policy variables. Part of the analysis concerns an investigation into trends in cattle numbers, changes in cattle biomass and the productivity of livestock in…

Economic and social impact of environmental degradation in Sudanese forestry and agriculture

The objective of this paper is to examine the interrelationships and links between population activities (mainly in agriculture and forestry) and environmental degradation in the Sudan, and their impact on the population at large and on women in particular. Most studies made in the area suggest that these activities and the environment are not in harmony. Despite its diversity and high potential,…

Directional climate change and potential reversal of desertification in arid and semiarid ecosystems

The objective was to determine if long-term increases in precipitation can maintain grasslands susceptible to desertification, and initiate a reversal of historic regime shifts on desertified shrublands. Perennial grass production and species richness in a multi-year wet period were hypothesized to be greater than expected based on precipitation in a sequence of dry years. These responses were…

Our Planet, Our Health, Our Future. Human health and the Rio Conventions: biological diversity, climate change and desertification

Health is our most basic human right and one of the most important indicators of sustainable development. We rely on healthy ecosystems to support healthy communities and societies. Wellfunctioning ecosystems provide goods and services essential for human health. These include nutrition and food security, clean air and fresh water, medicines, cultural and spiritual values, and contributions to…
