Harnessing energy from wind
Study looks at critical aspects of wind power development Posted on 20 Sep, 2022 10:24 PM

India’s ever-increasing energy demand is putting a heavy load on energy generating agencies. Shifting towards renewable energy entails a series of judicious steps in consultation with the government bodies, energy developers, market valuation, and consumers.

Renewable energy sector financing must scale rapidly
Investors deploying sizable capital as they are confident of India's long-run robust demand for RE (8–10 GW/year) Posted on 20 Sep, 2022 07:51 PM

India is amidst a monumental energy transition—with global consequences. India's population is primed to continuously grow, industrialize, urbanize, and electrify their lives. Over the next two decades, it will urbanize 300 million people, double building space, add 640 million AC units, and add 240 million road vehicles.

RE tariffs will be determined by PV module costs and financing costs.  (Image: ODT, Flickr Commons)
New landslide reporting tool uses social media and artificial intelligence
The system can detect landslide reports with a precision of 76% Posted on 16 Sep, 2022 10:57 AM

When landslides occur, their impacts are usually not discovered immediately beyond the attention of first responders or government agencies. Reliable spatial data becomes available to users based on the satellite return path and the route that it takes, image quality and processing time.

Climate change and disappearing forests
Measuring climate change velocity can greatly help to provide additional information on spatial variability of climate change and its implications for forest loss. Posted on 09 Sep, 2022 04:44 PM

Forests are being destroyed at an alarming rate world over with tropical forests - hot spots of biodiversity experiencing the largest declines.

Fishing turns fishy as climate change plays truant
Climate change is here to stay. How will it affect freshwater resources and inland fisheries in India? A study explains. Posted on 28 Aug, 2022 11:32 PM

Inland aquatic fisheries form an important source of livelihood for a significant proportion of population in India. Climate change is projected to have a huge impact on inland aquatic ecosystems and the fisheries sector in India. While there are a number of studies on the impacts of climate change on freshwater ecosystems and fish, most of these are from the temperate countries.

Himalayan lakes can potentially become long-term sinks of microplastics
Study looks at microplastic types in lakes of Ladakh Posted on 27 Aug, 2022 03:36 PM

Microplastic pollution is a growing environmental concern. Microplastics are plastic particles with sizes ranging from 1 μm to 5 mm. However, a clear consensus on the definition of microplastics is lacking and even the lower size limit varies among different studies.

Heavy metals being discharged into coastal waters
Assessing heavy metals in the coastal environment is a critical challenge Posted on 21 Aug, 2022 11:37 PM

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.
