Spatiotemporal Classification of Drought Severity
The growing number and effectiveness of earth observation satellite systems, along with the increasing reliability of remote sensing methodologies and techniques, present a wide range of new capabilities in monitoring and assessing droughts. In this paper, several drought features are analyzed and assessed by using remotely sensed Reconnaissance Drought Index (RDI). The developed methodology is...
متن کاملObjective Quantification of Drought Severity and Duration
Common weaknesses of current drought indexes were analyzed. First, most of the current indexes are not precise enough in detecting the onset, end, and accumulated stress of drought. Second, they do not effectively take into account the aggravating effects of runoff and evapotranspiration, which build up with time. Third, they have a limited usefulness in monitoring ongoing drought because they ...
متن کاملImpacts of recent drought and warm years on water resources and electricity supply worldwide
1 Recent droughts and heatwaves showed the vulnerability of the electricity sector to surface water 2 constraints with reduced potentials for thermoelectric power and hydropower generation in different 3 regions. Here we use a global hydrological-electricity modelling framework to quantify the impacts of 4 recent drought and warm years on hydropower and thermoelectric power usable capacity worl...
متن کاملWater Supply Security and Willingness to Pay to Avoid Drought Restrictions ∗
This paper studies Canberra households’ and businesses’ willingness to pay (WTP) to avoid drought water restrictions, using stated choice experiments. We find that customers evidence a lack of WTP to avoid most types of drought-induced restrictions. Respondents appear unwilling to pay to avoid low-level restrictions at all and to avoid higher levels of restrictions that are not in place every d...
متن کاملWater Supply and Health
Arguments over the relative importance of increasing consumption ('quantity') versus improving water safety ('quality') have been taking place since at least the beginning of the first United Nations water decade (the 1980s). For those living distant from a water source, using only around 3‐4 litres per person per day, and often suffering from hygiene related disease, the logical priority is to...
