1. Introduction:

The Nile Basin Initiative is implementing the project titled “Enhancing conjunctive management of surface and groundwater resources in selected transboundary aquifers: Case study for selected shared groundwater bodies in the Nile Basin”. Three pilot projects will be implemented in the three selected aquifer areas (Kagera) to demonstrate novel approaches for sustainable management of groundwater and conjunctive use of groundwater and surface water resources. The pilots were selected to illustrate appropriate innovative techniques for sustainable conjunctive use of groundwater and surface water. Successful pilots from this project will be scaled up through other national and sub-regional initiatives.

NBI intends to employ the services of Individual National Consultant to participate in and support the Supervision for the MAR Construction Works (Kagera shared Aquifer)- in consultation with the international consultant, and the implementation consultants. The assignment described in these ToRs is funded through NBI member country contributions, and Global Environment Facility through United Nations Development Program. This document presents the Terms of Reference for the Supervision for the MAR Construction Works. The Consultant shall be nominated by the local authorities in consultation with the focal institution.
