The Water Accounting study in Mongolia focussed on the Selenge river basin and one of the su b-basins (Sugnugur) where ADB intends to support the rehabilitation of an irrigation system. The analyses contributed to the Vegetable production and irrigated agriculture project (MON 51423-002) and the Implementing Innovative Approaches for Improved Water Governance project (MON 51099-001). In addition, a field-scale WP study was done for the 2 center pivots of the Plant Science and Agricultural Training and Research Institute, one of the beneficiaries of the study.
