(hierarchical order)

- Province - District - BISA - ISA - WUA - Channel command area -

and

- Regular raster -

Table 2 (c.f., 'Indicators implemented in WUEMoCA') gives information what crop type(s) and indictor(s) implemented can be selected at the above aggregation levels. Definitons of aggregation levels as implemented in the online information tool WUEMoCA are given below. Information on the availability of those aggregation levels implemented in WUEMoCa for the different countries contributing to the ASB is given in Table 3. Information on the spatial distribution of the irrigation zones within the maximaum irrigation extent shared by the Amu Darya and Syr Darya river catchments and the artificial water supply zone of the Kara Kum Canal in the ASB is given in Figure 1.
