Abstract:
This shapefile is part of the IGAD Minimum Medical GIS Database. 6 queries overlaid to produce image to the right. Shows IGAD crop production system zones (CPSZ) of East Africa that are predicted to be unsuitable for the S. mansoni-B. pfeifferi system due to average annual man temperatures of 27 C or above or annual moisture deficits of >-1300mm. The CPSZ polygon queries are superimposed on the annual composite of Tmax. Because CPSZ have a single value for each polygon area, 'sub-polygon' irrigated areas and sites near water bodies are not detectable by the CPSX query, but are by the dry season model based on Global 1-km climate surrogate. See Acta Tropica publication at: <http://www.parasitologyonline.com/parasitology/22/53/23/> show/toc.htt
Purpose:
To be used as part of the IGAD Minimum Medical GIS Database. The extrapolation of the GIS 'dry season model' query to neighboring countries in the IGAD zone of East Africa provides an idea of where environments may be suitable for S. mansoni.

Process_Description:
To develop optimum criteria ranges for the dry season, values for 5 km buffers around survey sites were extracted from the combined 2-year dry season composite map by iteratively fitting query overlay areas to the spatial distribution of sites with >=5% prevalence. Query best-fit results were 125-140 NDVI and 22-37 Tmax. This result represents the dry season model. The resulting dry season model had a positive predictive value of 97.0%.
