Groundwater plays an integral role in sustaining certain types of aquatic, terrestrial and coastal ecosystems, and the associated landscapes, both in humid and arid climatic regions. It is thus a key factor...

This briefing note explains the technical strategies to confront situations of excessive, and unstable groundwater exploitation, but the institutional framework for implementation is dealt with elsewhere...
The note reviews country legislation over groundwater resources, specifying many governments have introduced legislation to regulate groundwater development, and to constrain activities that might compromise...
The note provides an introduction to groundwater resource management, its scope and practice, and aims at clarifying the difference between surface water and groundwater, as follows. Groundwater differs...
This briefing note deals primarily with issues affecting initial development, and subsequent expansion of groundwater supplies, in areas underlain by minor aquifers, whose yield to water wells is both...
The note characterizes groundwater systems, reviews key concepts and frequent misconceptions, and explains how aquifers differ from one another. Groundwater flows generally take place in a myriad of interconnected...
Esta nota informativa trata principalmente de promover un enfoque integrador a la planificación de recursos hídricos a fin de que las aguas subterráneas sean incorporadas a la estrategia nacional de conservación...
This briefing note deals primarily with promoting an integrated approach to water resource planning whereby groundwater is incorporated into the overall national strategy for water conservation. Groundwater...
Esta nota informativa trata los temas que afectan el desarrollo inicial y la posterior expansión de los suministros de aguas subterráneas en zonas donde subyacen pequeños acuíferos cuyo rendimiento hacia...
Groundwater and surface water are intimately linked, being part of the same overall hydrological cycle. Aquifers discharge to surface water bodies, and can be recharged by them, depending on local conditions...
El principal mensaje de este informe es que el agua subterránea es un recurso extenso, pero oculto e inaccesible. A diferencia de las aguas superficiales, el volumen y la calidad de los acuíferos cambia...
Groundwater is an extensive, concealed and inaccessible resource, and (in contrast to surface water) changes in quantity and quality are often very slow processes occurring below large land areas. These...
The note explains groundwater resources are never strictly non-renewable. But in certain cases the period needed for replenishment (100s to 1000s of years) is very long in relation to the normal time-frame...
Las aguas subterráneas y superficiales están estrechamente relacionadas: pertenecen al mismo ciclo hidrológico. Los acuíferos descargan sus aguas en los cuerpos superficiales y éstos pueden recargarlos...
The note reviews how urban wastewater relate to groundwater, to what extent is wastewater a groundwater pollution hazard, and what types of measures are available for reducing risks, and increasing benefits...
Groundwater resources management has to deal with balancing the exploitation of a complex resource (in terms of quantity, quality, and surface water interactions) with the increasing demands of water and...
La gestión de recursos acuíferos debe mantener un equilibrio entre la explotación de un recurso complejo (en términos de cantidad, calidad, e interacción con aguas superficiales) y la creciente demanda...
