This document summarizes activities related to assessing and managing transboundary aquifers. It discusses that many aquifers cross political borders and need assessment to understand potential cross-boundary issues. The ISARM program leads efforts to improve understanding of transboundary aquifer issues. Assessments involve indicator-based analysis, developing information management systems, and establishing consultative bodies for countries to facilitate cooperation. The goal is to eliminate potential conflict and improve groundwater management and benefits.
