The main objective of this study is to assess public economic preferences for biodiversity conservation and water supply and to analyse the factors influencing those preferences. A survey based on the choice experiment method was carried out at Peñuelas National Reserve, Chile, an area that is threatened by both occasional forest fires and the growing housing market. The input of local administ...

As water is an essential component of the planetary life support system, water deficiency constitutes an insecurity that has to be overcome in the process of socio-economic development. The paper analyses the origin and appearance of blue as well as green water scarcity on different scales and with particular focus on risks to food production and water supply for municipalities and industry. It...

Important lessons from the past must be applied today if the crisis is to be averted. Sanitation has suffered from a lack of prioritization for as long as it has remained the poor relation ...

Groundwater recharge with reclaimed municipal wastewater presents a wide spectrum of technical and health challenges that must be carefully evaluated prior to undertaking a project. This review will provide a discussion of groundwater recharge and its management with special reference to health and regulatory aspects of groundwater recharge with reclaimed municipal wastewater. At present, some ...

The literature on water supply and health is strikingly heterogeneous in design, in method, and in conclusions (1) and “offers little in explaining water’s health impact beyond confirming the existence of a general association between improved quality and increased quantity of domestic water and a reduced incidence of enteric disease” (2). Several excellent recent reviews examine the relevant l...

This paper presents the water and contaminant daily simulation model of the total water cycle, called UVQ. The model has been developed to provide a means for rapidly assessing conventional and nonconventional approaches to providing water supply, stormwater and wastewater services to urban allotments, neighbourhoods and study areas. The model is placed the context of other such models develope...

Accordingly, preservationists traditionally have based arguments for protecting nature on its intrinsic rather than instrumental worth. These traditional arguments rest on aesthetic, moral, and spiritual rather than on economic values. Today, though, many environmentalists point to t...
