Targeting investments on shallow groundwater irrigation (Part 1)

This project serves to test and expand the applicability of the Bayesian-based decision tool TAGMI (Targeting AGwater Management Interventions), developed by SEI as part of CPWF-V1.

TAGMI provided recommendations for scaling-up the adoption of a specific irrigation technology. The project will specifically ground-truth and expand the TAGMI model adapted to petrol pumps for shallow groundwater irrigation (CPWF-RiU project) by:

1) Verifying the results of the model with field observations and experts' opinions;
2) Re-assessing the model structure (are the lines and relationships accurate? what should change?) and data sources (are there others to include? what organizations have the data?);
3) Exploring avenues for model refinement through additional data sources and spatial disaggregation;
4) Exploring the potential of the model to other pumping and groundwater application technologies; and
5) Exploring the relevance and data requirements of expanding the model to other areas in the wider Volta/Niger Basin.

The International Water Management Institute (IWMI) will be leading this project, with SEI and International Development Enterprises (IDE) as key partners.
