Understanding the endogenous factors that drive the population dynamics of malaria mosquitoes will facilitate more accurate predictions about vector control effectiveness and our ability to destabilize the growth of either low- or high-density insect populations.

Identifying human activities which influence degradation of catchment forests offers input/solutions for its management to the benefit of communities who depend on resources from the forest. Data were collected in 4 villages using questionnaire, in-depth interviews and focused group discussions. Results revealed that the main human activities disturbing

In Madina village, outside Accra, Ghana, children tease each other about whose urine has a redder color. Apart from being strikingly thin, they look healthy. Yet they could be affected by Schistosoma haematobium, a parasitic disease common in Africa, where local prevalence rates can exceed 50%. Early diagnosis ensures inexpensive and effective treatment and prevents stunted growth and developmental disabilities in children and bladder cancer or other organ damage in adults (3).

In 2009, giant African pouched rats trained to detect tuberculosis (TB) evaluated sputum samples from 10,523 patients whose sputum had previously been evaluated by smear microscopy. Microscopists found 13.3% of the patients to be TB-positive. Simulated second-line screening by the rats revealed 620 new TB-positive patients, increasing the case detection rate by 44%.

For several decades, a diverse literature has claimed that urban agriculture has the potential for hunger and poverty alleviation. This article reviews empirical data from equatorial Africa that touch on this assertion, updating the work on the subject published in the mid-1990s. Research, largely from East Africa but also including Cameroon in West Central Africa, appearing in several recent and currently emerging publications is assessed and compared. The article
