Biomass response to precipitation variability 1982-2000
This map shows the coefficient of variation of the maximum NDVI for the period 1982-2000, which is an indicator of the fluctuations in agricultural or natural biomass, which do not result from land use change and are related to current climatic variability.
The colors in orange and red express where the variability is the highest. As the CV of the maximum NDVI expresses the response of the vegetation biomass to climatic fluctuations, it is an impact indicator and hence evidence of the presence of ‘hot’ or ‘cool’ spots in different parts of CWANA.
The map shows several current hot spots:
- North Africa, from Morocco into Tunisia
- The Sahel, from Mauritania into Sudan, Eritrea, northern Ethiopia and turning south into Somalia
- The Fertile Crescent, from northern Syria, Kurdistan, turning southeast into Kuzistan and southern Iran
- The foothill zone north of the Tien-Shan and Pamir Central Asia mountain ranges
- The rangelands in the north of Central Asia
All these areas are characterized by severe droughts, degradation of land, water and vegetation resources, and sometimes famines.

Agricultural Resource Capital and Population Density
A high-potential agricultural resource base can be insufficient for a large rural population, whereas areas with lower potential for agriculture but also lower population densities can be sustainable. This map links agricultural resource poverty to population density.

Action and satellite sites of the Central Asia target region
Whereas in the WANA region there is sufficient contiguity to spatially define Benchmark Areas, this is not the case in Central Asia, hence an exclusive focus on Action Sites and Satellite Sites. Three Action Sites and a Satellite Site are planned in Central Asia, and one Satellite Site in the Caucasus.
The Aral-Turkestan Lowland Action Site (SRT2-AS1) covers the area around the Aral Sea in Kazakhstan, Turkmenistan and Uzbekistan and will primarily focus research on land reclamation, effective water management, and soil fertility increase.
The Action Site covering the Rasht Valley in parts of Tajikistan and Kyrgyzstan (SRT2-AS2) will primarily focus research on soil erosion and landslides control, livestock improvement, and processing and marketing of local products.
In the Ferghana Valley and Southern Kazakhstan (SRT3-AS1) research will focus on Improved water management, and agro-technical measures in crop production, fruits and vegetables, livestock and fodder.
In the Kashkadarya Region Satellite Site (SRT3-SS1) research will be conducted on plant breeding and seed production.
The Satellite Site in the Caucasus (the Kura-Araks Lowland, SRT3-SS2) will focus research on improvement of irrigation schemes and de-salinization of soils.

Absolute change in annual trend precipitation 1901-2007
This map is based on the Full Data Reanalysis Product Version 4 of the Global Precipitation Climatology Centre (GPCC). It has been obtained by linear regression fitted to the 107-year time series of annual precipitation of each 0.5x0.5 degree grid cell by the least-squares method and subsequent resampling to 0.008333 degree (about 1 km) spatial resolution. The map shows the average absolute change in mm/year as measured along the trend line between 1901 and 2007. With some exceptions (e.g. parts of the Black Sea coast and the rim of Central Asia mountains) the trend is negative in most of the region.
