africa_flood_occurrence Annual flood occurrence across Africa at ~500 m, 2001 to 2024, from two parallel IWMI series on one grid: flood_occurrence (the finer count, per-year maximum 17 to 37) and inter_annual_flood_occurrence (consistently smaller). Both start at 1 and neither is documented by the publisher, but their distributions are those of counts. Rebuilt from IWMI Africa GeoPortal tile services, which serve no downloadable raster.
africa_water_accounting Water accounting for continental Africa at ~1060 m: rainfall, total ET, green and blue ET, water yield and runoff, each as a yearly average and split into dry and wet seasons, averaged over 2003-2021. Water Accounting Plus output rebuilt from IWMI's Africa GeoPortal tile services, which serve no downloadable raster.

letaba_catchment Letaba catchment boundary (Groot and Klein Letaba), the area of interest the WaPOR 20 m downscaler is run over. Indexed as an ODC vector product so it can be used as a zonal unit alongside the raster products in this cube. The shipped geometry is a hand-digitised approximation that over-covers the published catchment by about 19%.
limpopo_cropland_10m Annual cropland extent mask at 10 m for the Limpopo basin. Each year is the union of the land-cover products that actually cover that year -- no product is carried into years it does not represent -- so the inputs differ from year to year and are recorded on every dataset as crop:sources. Tuned for smallholder recall rather than high-confidence agreement. Coverage and method vary by dataset; check crop:sources before comparing years.
limpopo_irrigated_field_survey Surveyed field locations for the Limpopo River Basin irrigated-area mapping: 525 sites in Zimbabwe, Mozambique, Botswana and South Africa plus a denser campaign in the Letaba catchment, each with its site id, country and how the site was chosen (sampling grid or known irrigation scheme). Locations only -- whether a field was found to be irrigated is not recorded. Recovered from the published field-trip maps; the source of record is the Earth Engine asset named in the caveat.
