The map presents evapotranspiration in the southern Africa region during the last two months of 2015, relative to the previous 5 year average. It is derived from Meteosat by EARS Earth Environment Monitoring in the Netherlands, a company specialized in satellite data for climate, water and food.
The 2014-15 growing season drought in southern Botswana
The map presents the relative evapotranspiration (RE) as derived from Meteosat by EARS Earth Environment Monitoring Ltd in Delft, the Netherlands. RE represents crop water use and is proportional to crop yield. In the map red and black colors point to serious water shortages and related yield losses.

Costs and lack of data are major challenges in de development of agricultural insurance in Africa. These problems have effectively been addressed and solved by EARS Earth Environment Monitoring from Delft, the Netherlands. The company has successfully developed and demonstrated a Meteosat based index insurance system that can provide affordable drought and excessive precipitation insurance to every farmer in Africa. The final technical report has just been published and is now available to interested parties.

Aiming to serve all African farmers, FESA Micro-insurance is growing fast. But, large scale crop insurance puts special demands. Using automated insurance design and monitoring tools, EARS has developed a geo-information approach to crop insurance. Mapped insurance designs can be provided for the entire region, thus allowing for unrestricted sales. This enhanced capability is also reflected in the offer to develop proof-of-concept, free drought insurance design.
Data and method Meteosat visual and thermal infrared images have been processed to relative evapotranspiration (RE) for the years 2004 to 2012. Relative evapotranspiration is a measure of plant available water and plant growth. It is the best possible agricultural drought indicator. RE data have been averaged for the months October to December 2012 so as to provide a measure of water availability in the starting phase of the growing season (figure A). The difference evapotranspiration (DE) relative to the previous 8 year is shown in figure B.
FESA Micro-insurance has developed drought and excessive precipitation insurance using 30 year of Meteosat data. In 2012 the technology has reached considerable scale, insuring potentially several hundred thousands of farmers. A major step towards affordable crop insurance, which will help African farmers to invest in better seed and fertilizer and in this way realize higher crop production and income.

Very low maize yields for most countries in the Eastern Africa region. The maize yields for the entire Eastern Africa region are expected to be very poor for most countries and food shortages can be expected to continue. This is most notable in the main growing areas of maize in Sudan, Somalia, Kenya and Ethiopia with yields between -8% and -14% from the 5-year average. With the worst drought in 60 years the famine can be expected to spread out through the region as crop yields are likely to remain far below the average yields.
The present document provides a preliminary forecast of crop yield expected at the end of the current growing season. Forecasts are provided from halfway the growing season (70 growing days). Although at that time the most critical stages of crop development have passed, the final outcome may still be subject to some change depending on how the second half of the season proceeds. Our forecasts are updated with the most recent satellite data available and distributed through email on a personal subscription basis every ten days.
Summary for Maize Yield in Southern Africa
Below average maize yields in 4 countries
The EARS FAST crop yield forecast points to below average maize yields in Swaziland (-9%) and Namibia (-8%). However, in Namibia the picture may still change as the growing season proceeds. In the main growing areas of Malawi and Mozambique yields are expected to fall 5-6% below average.
Overall a good production year for the Southern Africa region.
The current growing season is expected to give an above average maize yield in most countries of the Southern Africa region.
Swaziland performs best with yields expected to be +18% relative to the previous 5-year average. Most other countries as Angola (+7%), Lesotho (+3%), Malawi (+3%), Mozambique (+8%), South Africa (+7%), Zambia (+4%) and Zimbabwe (+7%) have good yield prospects.
Overall a good production year for the Southern Africa region.
The current growing season is expected to give an above average sorghum and millet yield in most countries of the Southern Africa region.
Swaziland and Mozambique perform best with yields expected to be +15% and +6% relative to the previous 5-year average. Also Zimbabwe (+4%), South Africa (+3%) and Malawi (+3%) have good yield prospects.
Following the alarming food security warning from Niger on 29 January 2010 (see message below) we have reviewed our FAST crop yield estimate for the 2009 growing season for West Africa. Please find below our Sorghum difference yield map, averaged by province. It is based on hourly Meteosat data of the whole 2009 growing season and the previous 5 year. These data have been processed to daily temperature, radiation and evapotranspiration, which then feed a crop growth model.
11 August 2009 - In Nigeria, the overall yield prospects are good with surpluses of +6% to +12% relative to the 5 years average. In the main maize growing areas, yields could be 18% higher than last year.
11 August 2009 - In Burkina Faso, Cameroon, Central African Republic, Ivory Coast, Gambia, Ghana, Mali, Nigeria and Senegal slightly above (up to +5%) five year average yields are anticipated. However local differences within these countries are seen. In Sierra Leone, Benin, Liberia and Togo slightly reduced sorghum yields of -2% to -3% are expected due to drought during the growing season. Sorghum and millet yield prospects are normal for Guinea and Guinea-Bissau (0%). In Niger the prospects are favorable, yield forecasts are 10% higher than last year and the five year average.
11 August 2009 - In large parts of the Rift Valley yields are expected to be 15% lower than the 5 years average due to drought, with local reductions of up to 50%. Compared to the yield of 2008, a reduction of about -10% is foreseen.
11 August 2009 - In large parts of the Rift Valley Province, yields are expected to be 17% lower than the 5 years average due to drought, with local reductions of up to 35%. Compared to the yield of 2008, a reduction of about -7% is foreseen.
