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 …

Significant salinity anomalies have been observed in the Arctic Ocean surface layer during the last decade. Our study is based on an extensive gridded dataset of winter salinity in the upper 50 m layer of the Arctic Ocean for the periods 1950–1993 and 2007–2012, obtained from ~20 000 profiles. We …
Cytoskeleton plays a vital role in stress tolerance; however, involvement of intermediate flaments (IFs) in such a response remains elusive in crop plants. This study provides clear evidence about the unique involvement of IFs in cellular protection against abiotic stress in rice. Transcript abundance of Oryza sativa intermediate flament (OsIF) …
This report discusses in detail the occurrence of coastal land salinity, its impact on crop yield and environment, and various management techniques to mitigate the adverse impacts, including those of coastal flooding arising from storm surges and anticipated climate change. The state-wise physiography and drainage, hydrogeology, and, causes and extend …
The location and persistence of surface water (inland and coastal) is both affected by climate and human activity and affects climate, biological diversity and human wellbeing. Global data sets documenting surface water location and seasonality have been produced from inventories and national descriptions, statistical extrapolation of regional data and satellite …
Recent salinity changes in the Southern Ocean are among the most prominent signals of climate change in the global ocean, yet their underlying causes have not been firmly established. Here we propose that trends in the northward transport of Antarctic sea ice are a major contributor to these changes. Using …
Groundwater abstraction from the transboundary Indo-Gangetic Basin comprises 25% of global groundwater withdrawals, sustaining agricultural productivity in Pakistan, India, Nepal and Bangladesh. Recent interpretations of satellite gravity data indicate that current abstraction is unsustainable, yet these large-scale interpretations lack the spatio-temporal resolution required to govern groundwater effectively. Here we report …
The province of Punjab is the main food basket of India. In recent years, many regions of Punjab are facing acute waterlogging problems and increased secondary salinity, which have negative impacts on food security of the nation. In particular, these problems are more pronounced in the Muktsar district of Punjab. …
The effects of global warming on water supply represent one of the greatest challenges for cities in the 21st century. City administrations are seeking ways to meet demand for water from growing populations while grappling with the issues presented by climate change - extreme rainfall and drought, rising sea levels …
After the 2011 Tohoku earthquake, thirteen thousand hectares of farmlands were damaged by massive Tsunami near coastal sites in Miyagi, Japan. Some eighty percent of the damaged farmlands have been recovered in 2014, but subsidence and high salinity groundwater make it difficult to completely remove salinity from the soil. To …
Munrothuruthu (‘Munroe Island’) is a place renowned for continuous settlement, in the Kollam district of Kerala. The Indian Ocean earthquake and Tsunami of 2004 triggered this major problem. The island is located at confluence of the Ashtamudi Lake and the Kallada River. Low lying regions of the island are facing …
The prime objective of the guidelines for evaluation of proposals/requests for the withdrawal of ground water, is to focus on a specific part of ground water management viz. ensuring sustainability of ground water both in terms of quantity & quality and also focus on land based management of ground water …
Subsurface drainage has been used for more than a century to keep water table at a desired level of salinity and waterlogging control. This paper has been focused on the impact assessment of pilot studies in India and some other countries from 1969 to 2014 . This review article may …
This paper presents the application of a new methodology for coastal multi-hazard assessment & management under a changing global climate on the state of Karnataka, India. The recently published methodology termed the Coastal Hazard Wheel (CHW) is designed for local, regional and national hazard screening in areas with limited data …
MADURAI: A survey has revealed that areas like Surya Nagar, Alagar Kovil Road and Iyer Bungalow have the best groundwater levels in the city, with water available at a depth of around 100 feet. The survey, carried out by volunteers of a social enterprise named Rainstock, recorded the groundwater and …
Of the many processes contributing to long-term sea-level change, little attention has been paid to the large-scale contributions of salinity-driven halosteric changes. We evaluate observed and simulated estimates of long-term (1950-present) halosteric patterns and compare these to corresponding thermosteric changes. Spatially coherent halosteric patterns are visible in the historical record, …
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 …
