Heavy metals being discharged into coastal waters
Assessing heavy metals in the coastal environment is a critical challenge Posted on 22 Aug, 2022 12:26 AM

In recent years, the impact of the wastes discharged in the Bay of Bengal has been significant due to high effluent inflow from secured sources. It was observed that the heavy metal concentrations in the Bay coast sediments were considerately high and varied among sampling points.

Floods – a boon than a bane!
Floods are not feared, but rather welcomed by the Mishing communities from Majuli island in Assam as they bring bountiful fish- a rich source of food, nutrition and livelihood for the community. Posted on 21 Aug, 2022 11:15 PM

Floods are often perceived as a destructive force in Assam and other parts of India.

Polluted water, hitchhiking microbes and the hidden threat of cholera in India
Better access to clean water coupled with health education to bring about changes in behaviour are critical to prevent exposure to dangerous cholera bacteria that lurk in untreated waters. Posted on 19 Aug, 2022 11:33 PM

Cholera outbreaks are frequent and steadily increasing in India, shows recent surveillance data.

Heavy metal contamination in the sediments of the Brahmaputra river
Study indicates an intermediate silicate weathering in the adjoining area Posted on 16 Aug, 2022 10:11 AM

The river Brahmaputra carries around 73 million tons of dissolved material annually, which accounts for approximately 4% of the total dissolved flux into the oceans (Singh et al., 2005). The dissolved chemical load and sediment flux of the Brahmaputra River has significantly higher rates of physical and chemical weathering than other large Himalayan catchments.

Collaborative management for sustainable livelihoods in the Sundarbans
The impacts as perceived by the community Posted on 15 Aug, 2022 07:42 PM

Sundarbans delta is the largest mangrove forest reserve in the world with distinct species of wild flora and fauna. It is a source of livelihood for several communities residing in the vicinity. The indigenous plants, extraction of honey and catching fish from rivers, lakes and rivulets have good economic value in surroundings markets.

A new index to quantify longitudinal river fragmentation
The Catchment Area-based Fragmentation Index (CAFI) can improve basin-wide conservation and development planning Posted on 15 Aug, 2022 03:35 PM

The loss of connectivity is a ubiquitous threat facing rivers worldwide considering the numerous river infrastructure projects that exist worldwide and continue to be commissioned to meet humanity’s growing demands for hydropower, flood control, and water supply. Not surprisingly, freshwater ecosystems are among the most altered and threatened globally.

Arsenic removal in groundwater
Use of low-cost Biosand filters and ceramic pot filters such as JalKalp and MatiKalp developed by Sehgal Foundation are greatly effective and promising options in providing sustainable solutions for arsenic removal in the country. Posted on 12 Aug, 2022 11:14 PM

Safe drinking water, a global concern

The safety and accessibility of drinking water is a global concern. The World Health Organisation (WHO) reports that 80 percent of diseases are waterborne. Contamination from the geological formations (termed geogenic contamination) is the major source of groundwater contamination.

India’s rivers in trouble due to high fertilizer load and heavy monsoons
This could lead to water quality crisis reinforcing the need for basin-specific management strategies Posted on 11 Aug, 2022 10:59 AM

Agricultural intensification in India has increased nitrogen pollution, leading to water quality impairments. The fate of reactive nitrogen applied to the land is largely unknown, however. Long-term records of riverine nitrogen fluxes are nonexistent and drivers of variability remain unexamined, limiting the development of nitrogen management strategies.

Taming water - Irrigation and drought protection in colonial India and the present
The irrigation at all costs mindset and narrow policies for drought protection during the colonial rule ignored rainfed agriculture and local practices that sustained agriculture in the Bombay Deccan. This continues even today. Posted on 10 Aug, 2022 07:12 AM

Following independence and with the advent of the green revolution, agriculture in India has been based on input intensive farming, and agricultural policies and investments continue to support irrigated agriculture. This excessive focus on irrigated agriculture has led to the neglect of rainfed agriculture.
