Coastal Flood Plain in 1931 - a fatal epizootic of sheep on a farm north of Lake Naivasha
Riverine Flood Plain
?? Scarcity of surface climate observations (both temporal + spatial)
NDVI == can be used as the cumulative response indicator of climatic parameters: precip, temp and their variability over time especially in arid and semi-arid areas == memory of climate
AP in 1931 - a fatal epizootic of sheep on a farm north of Lake NaivashaOperational Application
Surveillance Regions: Based on Savanna Mask
Persistence mapping of “above” normal vegetation conditions
Current rainfall at selected RVF monitoring sites almost same as 1997/98, continued
rainfall will maintain flood waters and elevate risk of RVF activity and other vector-borne diseases.
