The important attributes of macrobenthic community structure viz., species composition and number, population density, biomass, and dominance and diversity indices were measured at different depths and discussed in relation to pollution of Lake Naini Tal. The zone below 7 m depth, where anoxic conditions prevailed for most part of the year, showed complete absence of macrobenthos.

The analysis is done to reveal how light pollution affects protected areas. Hence, two new variables was created from combining the global protected area distribution data and nighttime lights data: a Protected Area Light Pollution Index (PALI) and a Protected Area Human Impact Index (PAHI).

Pune: Several pumped storage hydro-electric projects, which can add almost 21,000 mW, are in a limbo because of the power deficit in the state. These projects can see the light of the day only after the power situation improves.

A rush to extract methane from the depths of Africa's Lake Kivu could trigger a huge upwelling of suffocating gas, potentially affecting over 2 million people.

Africa's Lake Kivu contains vast quantities of gas, which makes it both dangerous and valuable. Anjali Nayar asks whether it is possible to tap the gas without causing a disaster.

Water is not distributed evenly over the globe. Fewer than 10 countries possess 60% of the world's available fresh water supply: Brazil, Russia, China, Canada, Indonesia, U.S., India, Columbia and the Democratic Republic of Congo. However, local variations within countries can be highly significant.

Less than 3% of the world's water is fresh - the rest is seawater and undrinkable.

- Global warming will likely drain more water from the Great Lakes and pose added pollution threats to the region's vulnerable ecosystem, environmental groups said in a report issued on Wednesday. Climate change could further reduce scant ice cover observed in recent winters, increasing evaporation rates and dropping water levels in the five lakes that collectively make up 20 percent of the world's surface fresh water.

In 1930, the ruler of the then princely state of Tripura commissioned the British company Martin and Burns to construct a summer resort for him. The Maharaja got his palace nine years later: in the

Tata Chemicals is getting considerable stick from conservation groups and environmentalists in Africa over its plan to set up a soda ash facility jointly with the Tanzanian government. It is being
