Water Pollution The demand for freshwater rises continuously as the world’s population grows. From 1940 to 1990 ,withdrawal of fresh water from rivers, lakes, reservoirs, and other sources has increased fourfold. Of the water consumed each year,69 percent is used for agriculture,23 percent for...

A recent example is the dry spell in Southeast Brazil, where due to a drought during 2013–15 the main reservoirs reached storage levels below 5%, leading to a severe water crisis for freshwater ecosystems and, consequently, 85 million people. It was aggravated by a combination of lack of ...

the main water resource for humans from prehispanic times to the present. Stable isotopes were used to establish the seasonal surface-water/groundwater interactions and the hydrological conditions in a lake of the Dry Pampean Plain (DPP), i.e., Lake Los Pocitos, to understand the mechanism ...

In this case, the loss in fish yield can sometimes be partially compensated by new fisheries in some large reservoirs, however this does not generally maintain biodiversity value and may only represent a tempo- rary benefit (Brink et al., 2018). In many cases, dams have been constructed ...
The main coalbed methane reservoirs of the Qinshui Basin are the No. 3 coal seam in the Shanxi Formation and the No. 15 coal seam in the Taiyuan Formation, of which the total thickness ranges from 7 m to 16 m (Cai et al., 2011). Download: Download high-res image (938KB) ...
