Reduce air pollution to avoid land conflicts due to solar projects, recommends study
Due to high air pollution, India is witnessing an estimated loss of US$ 245-835 million every year. Improvement in air quality will in turn improve the performance of the solar power projects, says a study.
According to the researchers who conducted the study, cleaner air and better performance of solar power projects would also mean that India could save a crucial resource like land by which conflicts with communities and the environment could also be avoided.
According to the study, aerosols in the atmosphere attenuate incoming solar radiation through scattering and absorption and this is known as the “atmospheric attenuation effect.” In addition, aerosols often get deposited over panel surfaces and affect their PV performances. High air pollution translates into low efficiency of solar power projects which leads to higher auxiliary power consumption (use of robots for cleaning the panels), or an increase in the use of water for cleaning the panels. What we need to understand is that if we are able to ensure better air quality, it would mean higher efficiency of solar power projects.
The study noted that the “loss of solar energy due to environmental factors like air pollution is not properly considered in renewable energy resource assessment” The study also said the assessment of solar resources should be incorporated while conducting the cost-benefit analysis of any air pollution mitigation plans in India.
75% of Kolkata’s groundwater is now brackish due to over-extraction: Study
Over-withdrawal of groundwater in Kolkata has created a ‘trough’ bigger than the city itself and turned three-fourths of its groundwater fully or partly brackish, a recently published study has stated.
The study is titled Hydrochemical fingerprinting and effects of urbanisation on the water quality dynamics of the Quaternary aquifer of south Bengal Basin, India. It has been carried out by groundwater experts from the Department of Environment Management, Indian Institute of Social Welfare and Business Management in Kolkata.
The study is based on data from the mid-1980s to 2016. It was carried out across a 436 square kilometre area located on the east and west banks of the Hooghly river and covered the Kolkata and Howrah cities and their peri-urban areas.
The experts have pointed out that shallow groundwater gets contaminated due to a range of reasons, natural as well as human-made. These include industrial water pollution, domestic sewage and others.

Rajasthan's Pratapgarh is suffering heavily from Illegal Tree Felling
Rajasthan's Pratapgarh is suffering heavily from Illegal Tree Felling by active Van Mafia in the area. Trees are mostly being felled for illegal land grabbing. Pratapgarh is renowned for second most green area of the state. The green cover of the area is decreasing continuously.
The forest departments seemed to not taking the matter seriously. Van mafias are active in the region from years, even the forest has lost 48sq km area of green cover from last year. Local residents also told about illegal tree felling during nights specially in Sita mata forest. People are accusing the forest department for not saving the forest.
