The need for enhanced environmental planning and management for highland aquatic resources is described and a rationale for integrated action planning is presented. Past action planning initiatives for biodiversity conservation and wetland management are reviewed. A re ective account is given of integrated action planning from ve sites in China, India and Vietnam.

Uganda lies almost wholly within the Nile Basin and is a country characterised as well-endowed with water resources. Receiving considerable inflows of aid since the early 1990s, some of this aid emerging after the 1992 Earth Summit in Rio de Janeiro enabled the country to begin a process of Integrated Water Resources Management (IWRM), taking the lead from Chapter 18 of Agenda 21.

This study looks at the groundwater issues in the dry zone of Sri Lanka and shows how the use of remote sensing with high-resolution images can help in groundwater management. A new approach is developed for automatic extraction of the location of agrowells using high-spatial-resolution satellite imageries. As an example, three pilot sites in three different aquifer systems in the country are considered, and their highresolution images are analyzed over two temporal time periods.

Springs are the major source of freshwater in many small mountainous watersheds within the Himalayan region. In recent years, their flow rates have diminished, but the reasons for this are not self-evident, and hence this paper reviews the methods to investigate Himalayan springs. The review reveals that chemical and isotope analyses – mostly water dating and stable isotope (e.g., d18O) analyses – could be an appropriate entry point to commence field investigations, because of their potential to map complex spring pathways, including linkages between aquifers.
