IWMI DIWASA Blue ET for Africa: Blue Water Evapotranspiration

IWMI DIWASA Blue ET for Africa is a dataset quantifying blue evapotranspiration, the portion derived from blue water sources like rivers, lakes, reservoirs, and groundwater used for irrigation. It was created by the International Water Management Institute (IWMI) and is available under a Creative Commons open license. The data helps assess water productivity in irrigated agriculture and supports sustainable water resource management.

Use Cases

• Assessing water productivity in irrigated agriculture based on blue water fluxes.
• Quantifying consumptive water use for irrigation based on evaporation and transpiration from irrigated fields.
• Supporting sustainable water resource management in water-scarce regions based on blue water source tracking.

Strengths

• Focuses on a key component of water accounting for agricultural management.
• Released under a Creative Commons open license, facilitating reuse.

Limitations

• Row count, file formats, and column-level documentation are unknown.
• Last update date is unknown; freshness unverified.
• Data may reflect geographic bias inherent to the aws_open_data platform.
