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 …
The very severe cyclonic storm Phailin, a category-5 hurricane, was developed over the north of Andaman and Nicobar Islands on 9 October 2013. Subsequently, it propagated towards north-northwest and made landfall at the Gopalpur coast, Odisha on 12 October. Chilika lagoon, the largest brackish water lagoon in Asia, is in …
Groundwater pollution due to anthropogenic activities may impact overall groundwater quality. Organic and inorganic pollutants have been routinely detected at unsafe levels in groundwater rendering this important drinking water resource practically unusable. Vulnerability of groundwater pollution and subsequent impact has been documented in various studies across the globe. Field studies …
Groundwater is an increasingly important resource for urban and rural potable water supply, irrigated agriculture, and industry, in addition to its natural environmental role of sustaining river flows and aquatic ecosystems. But major changes in land use that impact groundwater are taking place, as a consequence of population growth, increasing …
Ground water is a significant source for drinking, agricultural and aquaculture purposes in Godavari region. Groundwater if contaminated due to manmade activities cause concern on environment and human health. The aim of the present study is to review the impact of aquaculture on environment briefly and to assess the ground …
Saline water intrusion has caused damage to boro paddy seedlings on 350 bighas of land in Dumuria upazila of Khulna, reports UNB. Local sources said a section of influential people has lifted saline water for shrimp farming by cutting a cross-dam of the Water Development Board (WDB) in Shovna union …
Data presented at a seminar on climate change in Pakistan highlighted trends where this South Asian country, which stretches from high, snow-capped mountains to a deltaic coast, could be in for a sharp rise in average temperatures and extremely erratic weather. The seminar, held last month (29 December), analysed data …
Focusing trans-boundary water regime of Ganges- Brahmaputra- Meghna (GBM) basin, this situation analysis paper discusses the core issues related to environmental security through analyzing various environmental impacts and its significance at the national and regional level. Specifically, the scope of this paper pertains to transboundary water relations between Bangladesh and …
Strong evidence on climate change underscores the need for actions to reduce the impacts of sea-level rise. Global mean sea level may rise 0.18–0.48 m by mid-century and 0.5–1.4 m by the end of the century. Besides marine inundation, it is largely unrecognized that low-lying coastal areas may also be …
Harmful algal blooms (HABs) are becoming an increasing problem to human health and environment, including harmful effects on natural and cultured resources, tourism and ecosystems all over the world. Marine raphidophycean algae, Chattonella spp., have been implicated in major fish deaths in various parts of the world and are regarded …
With urbanization of coastal cities, marine pollution is becoming a severe problem. The rates of biodegradation, decomposition, and ratification of pollutants get slowed down due to salinity. The higher temperatures prevalent in tropical regions significantly affect reaction rates. Multiple factors influence the rate of biodegradation, making the process complex. Hence, …
The debate surrounding the safety of shale gas development in the Appalachian Basin has generated increased awareness of drinking water quality in rural communities. Concerns include the potential for migration of stray gas, metal-rich formation brines, and hydraulic fracturing and/or flowback fluids to drinking water aquifers. A critical question common …
The most used temperature and salinity climatology for the world ocean, including the Indian Ocean, is the World Ocean Atlas (WOA) (Antonov et al 2006, 2010; Locarnini et al 2006, 2010) because of the vast amount of data used in its preparation. The WOA climatology does not, however, include all …
Fundamental thermodynamics and climate models suggest that dry regions will become drier and wet regions will become wetter in response to warming. Efforts to detect this long-term response in sparse surface observations of rainfall and evaporation remain ambiguous. We show that ocean salinity patterns express an identifiable fingerprint of an …
A massive campaign will be taken up during the next five years, with the assistance of the local public sector units as well as the private sector, to grow 40 lakh trees in and around Visakhapatnam to combat the ill-effects of industrial pollution and haphazard urbanisation, according to Dr T. …
In late 2010 a group of professionals published a report of surveys conducted in the Sundarbans following the destruction caused by cyclone Aila in May 2009. This report shows how little we care to know about the people living in the delta. While the state government attempts to include it …
This study investigates the impact of monthly Ganges–Brahmaputra river discharge variations on Bay of Bengal salinity and temperature during the period 1992–1999. The Ganges–Brahmaputra river discharge is characterized by a well-defined seasonal cycle with strong interannual variations. The highest/lowest yearly peak discharge occurs in summer 1998/summer 1992, with 1998 value …
Accumulating evidence shows that the planet is warming as a response to human emissions of greenhouse gases. Strategies of adaptation to climate change will require quantitative projections of how altered regional patterns of temperature, precipitation and sea level could cascade to provoke local impacts such as modified water supplies, increasing …
Groundwater conditions in the multi-aquifer system in the Krishna River Delta, India, were studied through an integrated approach using hydrochemical, hydrogeological and isotopic techniques. This study was taken up because of the reported seawater intrusion into the groundwater system of this agriculturally rich region. The results, of hydrochemistry and environmental …
Water will be one of the critical drivers of peace and stability in South Asia in the second decade of the 21 century. If the first decade of the new millennium was shaped by terrorism, the next two decades (2010-2030) will witness issues around water dominating internal and external policies …
