respected colleague,

For downloading global data on spatio-temporal anthropogenic groundwater extraction at the watershed level, I recommend the following sources and references that provide available data on this topic:

Global Hydrology Resource Center (GHRC) - NASA GHRC contains various data on hydrological and water resources, including data on anthropogenic groundwater extraction. Their data includes global hydrological data at the watershed level.

• Website: GHRC - NASA

HydroSHEDS (Hydrological data and tools) HydroSHEDS is a project that provides global data on hydrological networks, which can be used to analyze anthropogenic groundwater extraction at the watershed level. These data are useful for hydrological models and water flow analysis.

• Website: HydroSHEDS

FAO - Food and Agriculture Organization (AQUASTAT) FAO, through its AQUASTAT system, provides data on water resources, including groundwater. AQUASTAT also contains data on anthropogenic groundwater extraction at the global level.

• Website: AQUASTAT - FAO

These sources provide data that could be useful for your analysis and research on anthropogenic groundwater extraction at the watershed level. To access the data, you may need to register on some platforms or contact the institutions that maintain the databases.

1. GWSP (Global Water Systems Project) Website:

GWSP Data Portal (GWSP) offers historical and modeled groundwater extraction datasets for large basins worldwide. it gives Spatiotemporal and basin-specific data types. 2. UNESCO International Groundwater Resources Assessment Centre (IGRAC):

Website: IGRAC Data Portal

IGRAC provides various maps and datasets, including groundwater abstraction and recharge data. It gives Basin-level and global datasets.

and also you can collect the data about hydrobiological study from the particular district TWAD Board and fisheries department.
