Rajahmundry, March 22: Coastal villages in West Godavari are being plagued by high saline content in their drinking water due to seepage of sea water into the ground water. Sources say that the main reason behind this is excessive quarrying of sand on the Godavari river bed.
The above ground biomass (AGB) and carbon stock of Excoecaria agallocha were estimated in western and central Indian Sundarbans for five successive years (2005-2010). The two sectors are drastically different with respect to salinity on account of massive siltation that prevents the flow of fresh water of the River Ganga to the central sector of Indian Sundarbans.
Hambantota District is a major paddy (rice) producing area in the southern coastal region of Sri Lanka. Communities here have been experiencing salt water intrusion into their rice fields, leading to reduced yields. This has been caused largely by seawater contamination of irrigation systems.
We present evidence that the Indian Sundarbans is experiencing the effects of climate change over the last three decades. Observations of selected variables, such as the surface water temperature, salinity, pH, dissolved oxygen, and transparency show significant long-term variation over a period of 27 years (1980
Australians Lesley and Doug McGrath have for decades battled ocean swells that have eaten away at the backyard of their multi-million dollar Sydney home.
They bought an old beach shack on Collaroy Beach in 1976 and replaced it with a two storey home anchored to the land by 12 meter (35 feet) long piers, a concrete slab, and an underground seawall of giant boulders.
Hydrochemistry in parts of the Lower Tista Floodplain in northwest Bangladesh is dominated by alkalies and weakly acid, having highest concentration of sodium cations and bicarbonate anions respectively. Groundwater is characterized by sodium-calcium and sodium-potassium cation and bicarbonate-chloride-sulphate anion facies, and genetically ‘normal chloride’, ‘normal sulphate’, and ‘normal carbonated’ type, and soft to saline.
Speakers at a discussion yesterday said as the frequency and magnitude of natural disasters has been increasing rapidly in coastal belt due to climate change impacts, the government should take specific steps to protect some 3.48 crore people in the areas.
People living in the coastal belts are becoming more vulnerable day by day, they added.
Pakistan can use its 27million acre of saline lands to cultivate algae, which is the best alternative feedstock to biofuel production, says a researcher at the Mie University of Japan.
