With the consequence of climate change, it gradually extends towards inland water and soil. This scenario of gradual salinity intrusion into the coastal areas of Bangladesh is very threatening to the primary production system, coastal biodiversity and human health, said researchers. The total amount of salinity affected land in Bangladesh …
Until the 1940s, the irrigation and drinking water needs of India were met by rivers, ponds, lakes, dugwells, and rainwater sources. However, in the middle of the 20th century India continually faced two daunting challenges: providing food for an ever-growing population and decreasing the burden of highly prevalent water-borne diseases, …
Land degradation, synonymous to desertification in arid, semi arid and sub-humid region, covers the processes adversely affecting productive capacity of land under different land use systems. Present paper reports the extent, type and severity of land degradation in south Asian countries. Impact of land degradation contributing factors including population and …
ON NOVEMBER 18, there was a dust-up between farmers and fishers at Murthikuppam in Puducherry’s Bahour Commune over who would get to talk to the environment ministry’s representative visiting the area. The representative from the ministry’s Bengaluru regional office, U Sridharan, was there to seek views on the partially constructed …
Ecological diversity in Sunderban is at the threshold of decline. The fragile land here is being swallowed every day by gradual sea level rise, coastal erosion and tropical cyclones. Besides the global cause of sea level rise i.e. thermal expansion of sea water also responsible is the land degrading anthropogenic …
Stable isotope (? 18O and ? D) and salinity measurements were made on the surface waters collected from the Southern Indian Ocean during the austral summer (25 January to 1 April 2006) onboard R/V Akademik Boris Petrov to study the relative dominance of various hydrological processes, viz. evaporation, precipitation, melting …
Using over 1.6 million profiles of salinity, potential temperature, and neutral density from historical archives and the international Argo Program, this study develops the three-dimensional field of multidecadal linear change for ocean-state properties. The period of analysis extends from 1950 to 2008, taking care to minimize the aliasing associated with …
Radiogenic isotopes (3H and 14C) and stable isotope (18O) together with TDS, EC and salinity of water were used to discriminate qualitative and quantitative groundwater age, probable recharge time, flow respectively in groundwater of Challaghatta valley, Bangalore. The variations between TDS and EC values of sewage, corporation water, bore and …
Water characteristics of Kandla creek, monitored seasonally from 2002 to 2006 at four locations (mouth, cargo jetty, oil jetty and junction), indicated significant increases in nutrients, petroleum hydrocarbons (PHc) and phenols from anthropogenic additions, while increases in turbidity, total suspended solids (TSS) and salinity from natural effects. Principal Component Analyses …
India has a long coastal line of over 7500 km supporting vast habitats such as lagoons, backwaters, estuaries, coral reefs and mangrove swamps. Among them, the mangrove ecosystem commands the highest importance because of its biological productivity and specialized diversity. After coral reefs, mangrove forests have the highest productivity among …
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. According to ground …
The waters in the Sunderban delta are fast changing in quality. The western waters are fresher, lighter and less saline while the eastern sector is saltier and less transparency. Both are warmer—a sure consequence of climate change. Abhijit Mitra’s team from the department of marine science in the University of …
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 …
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. Farmers had been using saline-resistant varieties …
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
Rajiv Shah | TNN Gandhinagar: An authoritative report put out by the Gujarat government has expressed serious concern over failure of the officialdom to fight increasing salinity ingress along the state
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 …
