[1] Water year indices and drought indices are helpful for categorizing water years into similar types, allowing water managers and policymakers to quantify years, visualize variability, and guide water operations. Many water management decisions, such as environmental flow requirements and water supply allocations, are based on water year type designations. They vary by region and index, but a...

Ecosystem restoration efforts have become a booming business in China. Billions of dollars are being spent annually to restore polluted waterways and ecosystems that have been degraded, fragmented, or paved over (Fu et al. 2007; Wang et al. 2007). However, China’s environmental sustainability index remains among the lowest in the world (World Bank 2009; Liu 2010). For all the money spent, there...

Hydropower accounts for about 16 % of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity – t...

The potential of wind power as a global source of electricity is assessed by using winds derived through assimilation of data from a variety of meteorological sources. The analysis indicates that a network of land-based 2.5-megawatt (MW) turbines restricted to nonforested, ice-free, nonurban areas operating at as little as 20% of their rated capacity could supply >40 times current worldwide con...

Surface westerly winds in the Southern Hemisphere have intensified over the past few decades, primarily in response to the formation of the Antarctic ozone hole, and there is intense debate on the impact of this on the ocean's circulation and uptake and redistribution of atmospheric gases. We used measurements of chlorofluorocarbon-12 (CFC-12) made in the southern oceans in the early 1990s and ...

Among the environmental barriers to plant growth and yield, drought, an icon of arid and semi-arid regions is the most important factor in reducing production. Teucrium polium L. is one of the most important medicinal plants of the family Lamiaceae that exists in these areas. In order to study the effect of drought stress on some physiological and morphological traits of Teucrium polium L., an ...
