DocumentMatching land cover and tsetse habitat 2013
Also available in:
No results found.The present study explores the relationship between tsetse vegetation types and standardized land cover datasets, produced in compliance with the Land Cover Classification System (LCCS). The analysis at continental level uses coarse resolution datasets (1-5 km) to explore the broad patterns of the association between tsetse fly and land cover. At a higher resolution, the customization of national maps of land cover of eight tsetse infested East African countries (FAO - Africover) provides va luable input to support the planning and implementation of trypanosomiasis control interventions. -
Book (series)The continental atlas of the distribution of tsetse flies in Africa 2024
Also available in:
No results found.Tsetse flies (Genus: Glossina) occur in sub-Saharan Africa, where they transmit trypanosomosis, a group of parasitic diseases that affect both animals and humans. Tsetse and trypanosomosis are a constant drain on the resources of poor African livestock keepers and they also impose a public health burden. Comprehensive data on the geographic distribution of tsetse flies is crucial to design evidence-based and cost-effective strategies against animal trypanosomoses, and it is also important in eliminating the human form of the disease. Despite this, the latest maps of tsetse distribution in Africa were published several decades ago. The present publication provides an update on the geographical distribution of tsetse flies in Africa. A total of 669 scientific publications spanning a period of 31 years (1990–2020) provided the input data, and almost 7 400 distinct geographical locations were mapped. Tsetse flies were recorded from a maximum latitude of 15° North in Senegal, to a minimum of 28.5° South in South Africa. Data coverage is uneven, and no eligible publication was found for Burundi, Guinea-Bissau, Liberia, Sierra Leone or Somalia. A dearth of information also affects a few other countries, such as Angola, the Congo, the Democratic Republic of the Congo and South Sudan. At the level of tsetse species, relatively abundant data were identified for the species of major veterinary and public health importance, especially of the riverine (palpalis) and savannah (morsitans) groups. By contrast, limited information is available on many species of the forest (fusca) group. The continental atlas of tsetse flies, in combination with the upcoming component on animal trypanosomosis, can be used by policy makers, practitioners and scientists engaged in the control and elimination of tsetse flies and trypanosomosis in Africa. It also provides a blueprint for national authorities to develop country-level information systems (i.e. "national atlases") to assist planning and monitoring of control activities at the national and local levels. -
Book (series)Standardizing land cover mapping for tsetse and trypanosomiasis decision making 2008
Also available in:
No results found.The habitat of tsetse fly (Glossina spp.) depends upon climatic conditions, host availability and land cover characteristics. In this paper, the Land Cover Classification System (LCCS), developed by the Food and Agriculture Organization (FAO) and the United Nations Environment Programme (UNEP), is proposed as a tool to harmonize land cover mapping exercises carried out in the context of tsetse and trypanosomiasis (T&T) research and control. Habitat modifications are increasingly indu ced by human actions, either at a global scale, as in the case of climatic change, or at a local scale, as in the processes of urbanization and agricultural expansion. The challenges posed in the future by trypanosomiasis are likely to be shaped by those factors to the extent that no appropriate intervention can possibly be contemplated without considering them.
