Reducing air pollution due to stubble burning in Northwest India
Philanthropy can play a role in mitigating air pollution and environmental degradation caused by agricultural practices in Punjab and Haryana. Posted on 16 Apr, 2021 07:58 PM

There is a predictability to the narrative around North India’s air pollution. Air that is unhealthy all year-round becomes unbreathable during winter, largely due to particulate matter in emissions from farm fires in Punjab, Haryana, and Western Uttar Pradesh.

Mosquito fish – invaders in disguise!
Gambusia or Mosquito fish, inspite of being recognised as highly invasive species, continue to be introduced in freshwater bodies for mosquito control in India. This needs to stop! Posted on 22 Mar, 2021 12:02 PM

Threats to freshwater bodies in India are many and include pollution, flow modification, overexploitation and habitat degradation. Besides these, introduction of invasive alien species is a growing problem in India threatening freshwater biodiversity leading to a decline in native species and compromising the health of freshwater bodies.

Dams and distress in the Himalayas!
Hydropower projects and compensatory afforestation plantations are spelling doom for the fragile Himalayan forest ecosystems. Urgent action is the need of the hour! Posted on 23 Feb, 2021 10:10 PM

Proliferation of hydropower development in the Himalayas is leading to extensive land use changes in the river valleys and threatening the diverse and fragile Himalayan ecosystems leading to deforestation, fragmentation, soil erosion and loss of forest biodiversity. These are a cause for serious concern for local communities, whose lives and livelihoods depend on these forests.
