The study of extreme events poses a great challenge to science as such events take place rarely. However, their effects on natural and man-made systems can be detected over a long period of time but also at a distance from the locations where they have occurred. Moustakas et al. (2018) developed an innovative method of analyzing […]
Karstic landscapes are shaped by the geomorphic work of water on a carbonate bedrock, with various mechanisms taking place at aquifer, soil subsurface, and surface flow level. Due to the water and sediment flow discontinuities introduced by the unpredictable location, dimensions, and geometry of the karst formations, monitoring and modeling relevant hydrologic and biogeochemical regimes […]
Spatially explicit assessments of alien species environmental and socio-economic impacts, and subsequent management interventions for their mitigation, require large scale, high-resolution data on species presence distribution. However, these data are often unavailable. This paper presents a method that relies on Random Forest (RF) models to distribute alien species presence counts at a finer resolution grid, […]
Soil salinity is a major soil degradation threat, especially for arid coastal environments where it hinders agricultural production and soil health. Protected horticultural crops in the Mediterranean region, typically under deficit irrigation and intensive cultivation practices, have to cope with increasing irrigation water and soil salinization. This study quantifies the beneficial effects of the Trichoderma […]
Chairs underwater, photo by yannishimself Water Is the Climate Challenge, Says World Bank Some worry that Yemen, where many farmers have replaced grape vines with more water-intensive qhat, will become the first modern country to literally run out of water. Panasonic Claims Their New Weather Model is the World’s Most Accurate Science Isn’t Broken, It’s just […]
Current climate models fed on emissions and more recently green house gas concentrations depict temperature trends with a far greater certainty than any other climate variable. Regardless of one’s view on the causes of global warming, this effect is foreseen at a more or less uniform way around the planet. On the other hand, future changes […]
Dr. Dennis Lettenmaier has had a long standing interest in the application of remote sensing to hydrologic problems and has contributed to the launch of several relevant scientific missions. So when Dennis announces that this “will be a big year for hydrology” there’s probably a good reason for it. He’s enthusiastic about NASA’s plans to […]
The CASCADE European Project strives to investigate such approaches and to fill knowledge gaps through a series of multi-scale experiments and integrated soil-water-plant modeling. At plant level, experiments include the simulation of drought, or prolonged dry summers, through rainfall exclusion experiments. Prototype roofs were constructed using polycarbonate sheets fitted in hydro-jet cut sea plywood designed by Manolis […]
2023 is now just 9 years away, and that is the year scientists predict that Jamaica will be an unfamiliar place for its inhabitants and visitors, a place with a wholly different climate. The coldest year in Jamaica after 2023 will probably be warmer than the hottest year anyone there has ever experienced. A recently published […]
A group of researchers lead by Zbigniew Kundzewicz recently published a paper concludes that the increase of population density is a far greater driver for floods frequency increase than climate change. Whilst scientists recognise that climatic factors internsify most parts of the hydrological cycle thus contributing to extreme precipitation and flooding, this linkage is very complex to accurately […]
