STAP/UNESCO Workshop Managing the Subsurface Environment: Integrated Managed Aquifer Recharge

[T]he significance of groundwater, and its intrinsic social and economic characteristics, are insufficiently recognized and valued in national development plans, or in the administration of water resources and the environment. The Scientific and Technical Advisory Panel (STAP) was, therefore, asked by the Global Environment Facility (GEF) to identify the principal threats, and strategic issues on groundwater.

In response, STAP convened a workshop on strategic priorities and options in groundwater resources in April 2004. The workshop recognized that Managed Aquifer Recharge (MAR) is integral to the management and sustainability of groundwater resources. Furthermore, the workshop acknowledged that MAR technologies can help address threats to groundwater (e.g. aquifer degradation due to salinization and seawater intrusion).

The GEF, therefore, asked STAP to convene a second workshop on managing the subsurface environment, with a focus on MAR. The purpose of the workshop was to assess the effectiveness of MAR, including, and in combination with related technologies, such as water reuse, in a range of hydrogeological and environmental settings. These included: transboundary water impacts in international waters, the impacts of extreme climatic events on groundwater recharge/storage, and groundwater management for sustaining groundwater-dependent ecosystems.
