Somalia: Climate Data Update - Monthly Rainfall and NDVI, April 2013


In the month of April 20132, the Gu (April – June) rains were heavy in the 1st dekad, but slightly declined in the 2nd and 3rd dekads across Somalia. Significantly above average rainfall has been recorded in some stations in Togdheer, Sool, W. Galbeed, Mudug, Bay, Gedo, Hiran and the Shabelle’s (Map 1 and Table 1). Enhanced rainfall in Somalia and in Ethiopian highlands, in the first dekad of April increased river flows along the two rivers and subsequently led to floods in Middle Shabelle (Jowhar and Wanlaweyn) and Lower Shabelle (Kurtunwarey and Balad). In Jowhar, the river burst its banks along Tugarey, Gashanle, Eji, Huriwaa and Mandeere villages. In Kurtunwarey heavy rains led to flash floods affecting Doorar, Towfiq, Aros Eber and Afgoye Yare villages. Floods caused by the torrential rainfall also affected Bardheere (Gedo) and Baidoa (Bay) districts. The floods caused crop damage and displacement of populations and hampered movement of people and goods.

Satellite derived Rainfall Estimates (TAMSATRFE) confirm heavy rains in the 1st dekad of April and also the subsequent decrease of rains in the 2nd and 3rd dekad in the northern and central regions (Maps 2-5). However, field reports indicate that the Sanaag (Golis of Lasqoray and Gebi) and Sool (Nugaal valley bordering Garowe) regions received depressed rainfall. Normalized Difference Vegetation Index (NDVI) for April 2013 depicts tremendous greening of vegetation across Somalia, which is attributed to exceptional rainfall performance in most areas (Maps 6,8 and 10). Insignificant decrease of vegetation vigor is only visible in small pockets of W. Galbeed, Bay, Gedo, L. Shabelle and the Jubas.

March and April Gu rains have profoundly improved pasture and browse conditions and replenished surface water catchments thereby effectively reducing the water shortages experienced during Jilaal. Milk production increased as a result of improved livestock body conditions. Planting, replanting and weeding activities have been taking place in the agro-pastoral and riverine livelihoods. However, in the regions of Lower Shabelle and Middle Shabelle floods inundated large areas under standing crop. Pest infestation has been reported in Bay (Dinsor and Qansadere), parts of Wanlaweyn in Lower Shabelle and the cowpea Belt of Central. Weeding activities have been hindered in parts of Middle Shabelle due to the continued heavy rains.
