Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. The tropical regions of the biosphere are the most biogeochemically active coastal regions and represent potentially important sinks of C in the biosphere.

Leaf fall and reproductive phenology of Avicennia marina assessed during 1982-83 using litter fall collections from twenty-five sites in Australia, Papua New Guinea and New Zealand revealed major trends with latitude. Flowering shifted from NovemberDecember in northern tropical sites, to May-June in southern temperate sites. Periods between flowering and fruiting increased from two to three months in tropical sites to ten months in southernmost sites. Leaf fall was more variable with unimodal annual peaks in temperate sites and often multimodal patterns in the tropics.

Only the combined study of all the proposed power projects on the Konkan coastal belt, will give the real picture of the possible impact on the environmental of these plants, says the Bombay Natural History Society (BNHS).

The 200-km-long Konkan coastline is expected to have around 15 thermal power plants, with a capacity of around 23,000MW.

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).

Mangroves should not be used as sewage disposal sites. It is killing them. Mangroves grow in highly saline, coastal waters, representing a very unique ecosystem.

Mangroves are typical group of plants which are adopted for survival in sheltered brackish-water habitats along coasts of tropical and sub-tropical regions. Maharashtra is one of the important coastal state

Dumper trucks with BMC logo on them bound for the Mulund dumping ground dumped solid waste in the mangroves itself Brihanmumbai Municipal Corporation's dumpers carrying solid waste from Mumbai are allegedly dumping it in the mangrove forests at Kolshet in Thane. The dumpers, according to Shiv Sena corporator Pandurang Patil, bearing BMC labels dump solid waste into the mangrove cover at the edge of Thane creek.

Those dumpers that are found disposing off their waste on the mangrove cover on the way, according to the letter, should be impounded and fined for the act. Venkatesh Bhat, the Deputy Municipal Commissioner (DMC) TMC Headquarters informed that it was the primary duty of the district collectorate to check the slaughter of mangroves. He added that civic commissioner Nandkumar Jantre held meetings with the collector and officials of the Maharashtra Maritime Board (MMB) few days back and highlighted the problem. Bhat assured that the civic officials would keep an eye on such dumpers and fine those who are found illegally dumping solid waste into the area. He also informed that several civic dumpers were confiscated in Thane in the past and the TMC would not hesitate to seize BMC dumpers carrying out the illegal act of dumping garbage into the wetlands in future. The TMC, however, came under pressure from the standing committee as well. Rajan Kine, chairman of the civic Standing Committe has taken a serious note of the incident and directed the corporation to ban the passage of BMC dumpers from the city of Thane altogether earlier, these dumpers refused to pay entry taxes for using the TMC roads.
