Somalia: Climate Data Update - Monthly Rainfall and NDVI, August 2012


August 2012 rains were generally confined to northern regions (Karan) and the coastal areas of Juba and Shabelle regions (Haggaa) in the south. Rain gauge stations (Map 1 and Table 1) recorded above average rains in Borama (199mm), Qulenjeed (112mm), Wajaale (101mm) , Odweyne (68mm) Burao (54mm), Hargeisa (60mm), and Gebiley (122mm); light showers were recorded in Jammame (26mm) and Jowhar (11mm). According to field reports, Hargeisa and the surrounding areas experienced torrential rains with strong winds and thunderstorms leading to flash floods in some isolated areas. Light erratic rains precipitated in some parts of East Golis Mountains near Erigavo and Badhan districts in Sanaag region; some of the areas received heavy precipitation leading to damage of houses. Unusual showers were also reported in Bari and Sanag regions.

Satellite derived Rainfall Estimates (RFE) (Maps 2-5 and 9) confirm the rains in above mentioned areas. In the South, the satellite shows good rainfall in small pockets of Badhadhe district in Lower Juba. Similarly, RFE indicates some light showers in the agropastoral, coastal and pastoral areas of Central. These however are not consistent with the field reports indicating no rains.

Vegetation conditions are normal in most of northern and central Somalia, as indicated by Normalized Difference Vegetation Index (NDVI) for August 2012 (Maps 6-10), which is close to the long-term average (LTA). However, a continued deterioration of pasture is evident in some areas in the South. Small decrease in vegetation is depicted in small to large areas in Bay, Middle Shabelle and Middle Juba. Large decrease in vegetation vigor is evident in Lower Shabelle (riverine, agropastoral, and South - East Pastoral) and Juba (Lower Juba agropastoral and riverine, large areas of Southern Inland and South - East Pastoral).

Field reports indicate a continued normal pasture and water conditions in many parts of the country with the exception of pastoral areas in the Jubas and Lower Shabelle. In the Northwest, crops demonstrated significant improvement with good harvest prospects in O c t o b e r- N ove m b e r. L ive s t o ck b o dy conditions are generally good; normal livestock migration is reported across the country. The rains have slightly improved water resources and are expected to boost biomass accumulation, hence pasture availability.
