Peat swamp forest have a high economic value and are potential for agricultural development. However, peatlad fragile ecosystems because they easily damaged difficult to restore. The main problem of all peat soil types is their irreversible drying. In this condition the easy burning, unable store water, if groundwater far from surface, plants will be stressed lack water. Therefore support susta...

Soil conservation practices have been widely implemented on the Loess Plateau to reduce severe soil erosion in north-central China over the past three decades. However, the hydrologic impacts of these practices are not well documented and understood. The objective of this study was to examine how water yield has changed after implementing soil conservation practices that resulted in changes in ...

Birds living in desert environments have been the preferred models for the study of physiological adaptations to water scarcity. Passerine birds living in marine coastal habitats face similar problems, yet physiological adaptations to water conservation in such species have been poorly documented. We measured total evaporative water loss (TEWL) and rates of oxygen consumption (VO2) in three spe...

Stochastic optimization is used to estimate the willingness-to-pay WTP of individual households and groups of households for changes in a combination of probabilistic water supply reliability and retail price of water. By modeling the financial and “perceived” costs of implementing longand short-term conservation options and assuming rational expected value cost minimizing behavior, economic de...
