Agro-ecosystems impact malaria prevalence: large-scale irrigation drives vector population in western Ethiopia

Prevalence and impact of disability in north-western Ethiopia.

PURPOSE To assess the prevalence and impact of disability in one urban and three rural areas in north-western Ethiopia. METHODS The study design is cross-sectional and quantitative. Data was collected by using pretested and standardized structured questionnaires containing socio-demographic characteristics, type of disability, functional, and social dysfunction. RESULTS A total of 932 indiv...

Impact of Irrigation Extension on Malaria Transmission in Simret, Tigray, Ethiopia

Poor subsistence farmers who live in a semi-arid area of northern Ethiopia build irrigation systems to overcome water shortages. However, there is a high risk of malaria transmission when increased standing water provides more favorable habitats for mosquito breeding. This is a serious problem because there are many barriers to malaria control measures and health care systems in the area. Using...

The Effective Population Size of Malaria Mosquitoes: Large Impact of Vector Control

Malaria vectors in sub-Saharan Africa have proven themselves very difficult adversaries in the global struggle against malaria. Decades of anti-vector interventions have yielded mixed results--with successful reductions in transmission in some areas and limited impacts in others. These varying successes can be ascribed to a lack of universally effective vector control tools, as well as the deve...

Large Scale Environmental Assessment and Degradation Management: The Case of Food Insecurity in Ethiopia

Spatio-temporal variation in malaria transmission intensity in five agro-ecosystems in Mvomero district, Tanzania.

In Africa, malaria is predominantly a rural disease where agriculture forms the backbone of the economy. Various agro-ecosystems and crop production systems have an impact on mosquito productivity, and hence malaria transmission intensity. This study was carried out to determine spatial and temporal variations in anopheline mosquito population and malaria transmission intensity in five villages...
