OBJECTIVE NSW has just experienced its worst drought in a century. As years passed with insufficient rain, drought-related mental health problems became evident on farms. Our objective is to describe how, in response, the Rural Adversity Mental Health Program was introduced in 2007 to raise awareness of drought-related mental health needs and help address these needs in rural and remote NSW. Th...

Droughts can be characterized by their severity, frequency and duration, and areal extent. Depth-area-duration analysis, widely used to characterize precipitation extremes, provides a basis for evaluation of drought severity when storm depth is replaced by an appropriate measure of drought severity. We used gridded precipitation and temperature data to force a physically-based macroscale hydrol...

Governments, aid organizations and researchers are struggling with the complexity of detecting and monitoring drought events, which leads to weaknesses regarding the translation of early warnings into action. Embedded in an advanced decision-support framework for Doctors without Borders (Médecins sans Frontières), this study focuses on identifying the added-value of combining different satellit...

Meteorological drought in the Hadley Centre global climate model is assessed using the Palmer Drought Severity Index (PDSI), a commonly used drought index. At interannual time scales, for the majority of the land surface, the model captures the observed relationship between the El Niño–Southern Oscillation and regions of relative wetness and dryness represented by high and low values of the PDS...

drought is universal phenomenon that can occur everywhere and can cause harmful impacts on human beings and natural ecosystems. thus, it is very important to study drought character ristics part of for water resources management. in this study, the standardized precipitation index (spi) is used for drought frequency analysis in isfahan province. after collecting the precipitation data in the pr...

Severe droughts have been associated with regional-scale forest mortality worldwide. Climate change is expected to exacerbate regional mortality events; however, prediction remains difficult because the physiological mechanisms underlying drought survival and mortality are poorly understood. We developed a hydraulically based theory considering carbon balance and insect resistance that allowed ...

About one-third of the world's rice area is in rain-fed lowlands and most are prone to water shortage. The identification of genes imparting tolerance to drought in the model cereal plant, rice, is an attractive strategy to engineer improved drought tolerance not only rice but other cereals as well. It is demonstrated that RNAi-mediated disruption of a rice farnesyltransferase/squalene synthase...

This paper describes the evolution of drought-related public policies in Northeast Brazil (NEB). Using a historical approach, we show that the evolution of public policy has not been characterized by abrupt shifts, but has instead been shaped through debates between renowned intellectuals. The resulting public policies formed a hydrological infrastructure that delivers clean water needed for ro...
