aWhere Case Study: South Sudan

aWhere’s latest study of South Sudan shows potential for agricultural growth with positive rainfall totals over the past few months but also variability across the region. Our localized weather content illuminates these trends and allows farmers, governments, and decision-makers to #AdaptOurWorld NOW to climate change.

Weather Insights

South Sudan has much potential to be a high-yield producer of maize, millet, sorghum, and other staple crops. The map below of the precipitation over potential evapotranspiration (P/PET) from May-August (120+ day growing season) is largely >1 which means that the conditions for vegetative growth are ideal and precipitation exceed evapotranspiration. This translates to little water restriction to support reliable yields. The weekly climate charts below show the rainfall patterns from March – September 2019 and highlight potential areas of variability which require additional planning. The rainfall totals are high but the distribution of precipitation varies.
aWhere’s in-time data can help farmers and governments to plan for this variability and preserve their agricultural investments.


South Sudan May, June, July, and August total rainfall compared to the 2008-2018 average shows above average rains nearly everywhere across the country. The few areas with lower than normal rains were not droughty though some water stress likely occurred over short periods. Yield impact from water stress is likely minor and not unusual. South Sudan has the potential to grow nearly every food crop.
With typically 120+ days of good rains and positive P/PET, a regional bread basket awaits and the need for this land to return to production is growing. A key challenge in this region is civil unrest which has hampered and imperiled recent investments.

While South Sudan has great potential for agriculture, the current political situation is a barrier as civil unrest can greatly inhibit government and foreign investment in agriculture. This region suffers from severe food insecurity due in part to high food prices and food shortages.

Detailed elevation models South Sudan can provide the foundation for hydrologic planning: Where can surface runoff be captured for irrigation or to support groundwater recharge?

Daily weather data (aWhere provides 7,472 complete virtual observation stations for South Sudan) drives models to predict outcomes for both agriculture and hydrology.


aWhere weather data and models can help farmers in South Sudan adapt to weather variability and support policy development to deliver economic resilience to climate change in agriculture, energy, health, and trade (domestic and international). Weather variability is increasing but with timely insights farmers can take appropriate action such as changing crops or varieties, timely planting, fertilizing, harvesting and grain conditioning operations to maximize yield, quality and food safety.
