With increasing pressures from global changes (urbanization, climate change, etc.), cities in Africa will experience difficulties in efficiently managing water resources. Most of the urbanization in Africa over the next 30 years will occur in fast-growing small towns that lack mature infrastructu...

For a long time, trypanosomosis, spread by the tsetse fly Glossina, constrained human settlement in the Lambwe Valley, a south-western Kenya rangeland. After lengthy efforts to control tsetse over many years, the valley is currently experiencing an increase in human population growth rate, and r...

Rapid growth of the human and livestock populations in sub-Saharan Africa is creating unprecedented increases in food and feed demands. These population pressures on a fixed landbases are likely to promote severe competition for resources and drive agriculture progressively towards intensificatio...

The spatial distribution and growth of human populations have been overlooked by current debates concerning the impact of rural–urban migration for forest conservation in tropical countries. We investigated human settlement and population change in the Brazilian Amazon, combining government censu...

The massive loss of quantity and quality of natural forest cover in Indonesia threatens an important source of foreign exchange and employment. Several studies and government policies indicate that population growth, particularly among small landholders, is the principal cause of deforestation. A...

Dung counts have been widely used to estimate duiker abundance and densities in tropical African forests. However, one of the major limitations of this method is that species’ identification of dung based on morphological characteristics is extremely difficult in most cases. Some authors made the...

General measures summarizing the shapes of mortality and fecundity schedules are proposed. These measures are derived from moments of probability distribution related to mortality and fecundity schedules. Like moments, these measures form infinite sequences, but the first terms of these sequences...

Swidden cultivators are often found as a distinct category of farmers in the literature, but rarely appear in population censuses or other national and regional classifications. This has led to a worldwide confusion on how many people are dependent on this form of agriculture. The most often cit...

Meeting the dual objectives of food security and ecosystem protection is a major challenge in sub-Saharan Africa (SSA). To this end agricultural intensification is considered desirable, yet, there remain uncertainties regarding the impact of climate change on opportunities for agricultural intens...
