Government has issued a 21-day ultimatum to residents of 11 villages that have encroached on Lubigi wetland located northwest of Kampala.

Climate change is dialing up the pressure on species around the world.

The passing away of Dhrubojyoti Ghosh, the engineer-turned-internationally acclaimed ecologist, on February 16 has left the East Calcutta Wetlands more vulnerable than ever.

We used a first-of-its-kind comprehensive scenario approach to evaluate both the vertical and horizontal response of tidal wetlands to projected changes in the rate of sea-level rise (SLR) across 14 estuaries along the Pacific coast of the continental United States. Throughout the U.S. Pacific region, we found that tidal wetlands are highly vulnerable to end-of-century submergence, with resulting extensive loss of habitat. Using higher-range SLR scenarios, all high and middle marsh habitats were lost, with 83% of current tidal wetlands transitioning to unvegetated habitats by 2110.

NAGPUR: Five months after wetland rules were notified by the Centre, state government has finally constituted a 21-member Maharashtra State Wetland Authority (MSWA) under environment minister.

Global warming and direct anthropogenic impacts, such as water extraction, largely affect water budgets in Mediterranean wetlands, thereby increasing wetland salinities and isolation, and decreasing water depths and hydroperiods (duration of the inundation period). These wetland features are key elements structuring waterbird communities. However, the ultimate and net consequences of these dynamic conditions on waterbird assemblages are largely unknown.

Inorganic phosphorus (P)-solubilizing bacteria (IPSB) and organic P-mineralizing bacteria (OPMB) were isolated from bacteria that were first extracted from the rhizosphere soil of a natural wetland and then grown on either tricalcium phosphate or lecithin medium. The solubilizing of inorganic P was the major contribution to P availability, since the isolated bacteria released much more available P from inorganic tricalcium phosphate than lecithin.

Last year, residents had recovered around 25 huge bags of garbage, mostly with beer bottles from the area.

Wetlands cover 5–10% of the earth’s terrestrial surface. They are important ecosystems that supply goods and services for human wellbeing.

Bed sediment samples were collected along the 9.5 km long inlet channel of Chilika lagoon, east coast of India during low freshwater discharge and low rainfall condition. Distributions of bed sediment along with its texture were studied in detail. Bivariate plots between mean, sorting, skewness and kurtosis of sediments revealed definite grouping pattern. The study, through C-M plot, indicates that the prime factors for transportation of sediment within inlet channel of Chilika lagoon are rolling and bottom suspension during period of low discharge and low rainfall (November-June).
