Flood Impact Assessment in Jonglei South Sudan, 31 August 2020

Key Highlights from the report: (a) This year’s widespread flooding and waterlogging across the country is expected to result in impacts that are similar or worse than those of last year. The overall impact assessment on crop production is yet to be done, but an assessment was done for Jonglei state, which is more affected by the flooding. (b) Way above-average rainfall and overflowing of the Nile River and its tributaries in June/July negatively affected growing crops and livestock, and caused displacement of communities, in nine counties of Jonglei State where the impact assessment was undertaken. (c) These earlier than normal, above-average rains caused, and continue to cause in some areas, displacement of human population and damage to crops and livestock. (d) The floods found the crops at different stages of growth and will likely result in lower yields, particularly for those crops found at vegetative stage, compared to those at maturity stage and with a higher tolerance to waterlogging. (e) According to the assessment done in August in Jonglei State, about 45 percent of the total cereal area was damaged by floods in the nine flood-affected counties. (f) While harvesting of crops is expected to start in September, the production loss due to flood damage is estimated at 26 892 Ha of cultivated land which translates to an estimated loss of 11 916 tonnes of cereals in the nine flood-affected counties, with anticipated negative impacts on the food security situation of the affected population. (g) About 72 percent of the livestock population in the four counties of Twic East, Duk, Bor South and Canal Pigi were affected by the floods. An estimated 6 000 heads of cattle, 36 150 goats and 5 400 sheep are reported to have died in June and July due to the floods, representing 4.8 percent of the affected livestock population in the four counties. (h) Flooding has created conditions conducive for outbreak of animal diseases such as Rift Valley fever, pneumonia, foot rot, increased worm burden, anthrax, black quarter, trypanosomiasis, hemorrhagic septicemia among others. Pastures have also been inundated increasing the risk of animal deaths due to starvation. (i) This year’s flooding has spread beyond the traditionally flood-prone areas in Jonglei, and the resultant displacement of communities and damages to crops and livestock are much higher than the previous years.

However, there are higher chances of above normal to normal rainfall over parts of South Sudan, western Ethiopia, southwestern Uganda, northeastern Rwanda and Southern Tanzania, and increased likelihood of normal to below normal rainfall over much of Somalia, southeastern Ethiopia and eastern Kenya. The consensus mean temperature outlook for March to May 2018 season indicates an increased likelihood of warmer to normal temperatures over much of the eastern parts, normal to cooler than normal temperatures over central parts and cooler to normal temperatures in the western areas of the GHA region. The major processes considered are the evolutions of the global Sea Surface Temperatures (SSTs) including the neutral phase of the Indian Ocean Dipole and the anticipated transition in the Central Equatorial Pacific from La Niña to ENSO-Neutral conditions during the forecast period. Regional circulation systems that predominantly influence climate over the region during this season were also taken into consideration. This outlook is relevant only for the March-May 2018 season for relatively large areas of the region. Local and month-to-month variations might occur as the season progresses. It is likely that episodic heavy rainfall events leading to flash floods might occur even in areas with an increased likelihood of near to below normal rainfall and dry spells may occur in areas with increased likelihood of above normal to normal rainfall. It should be noted that parts of the region that have been experiencing drought conditions, and persistence of depressed rainfall would have far reaching implications. The IGAD Climate Prediction and Applications Centre (ICPAC) will provide regional updates on regular basis while the National Meteorological and Hydrological Services (NMHSs), that are expected to downscale this forecast to country level, will provide detailed national and sub-national updates.

GHACOF 47 October-December 2017 - FAO Key Messages

The Forty Seventh Greater Horn of Africa Climate Outlook Forum (GHACOF 47) was convened from 21st to 22nd August 2017 at Zanzibar, Republic of Tanzania by the IGAD Climate Prediction and Applications Centre (ICPAC) to formulate a consensus on regional climate outlook for the October to December 2017 rainfall season over the Greater Horn of Africa region (GHA) under the Theme “Preparedness for potential El Niño event and related impacts”.

Generally, the October to December 2017 rainfall performance over most parts of South Sudan is predicted to be near normal. However, some areas in the South and South-western part of South Sudan are forecast to receive above-normal rainfall during the October to December 2017 period.
