Shoddy impact assessments, mining and ruin in Goa
A study finds that weak environmental assessment reporting on the adverse impacts of mining has spelled doom for Goa’s environment. Aarti Kelkar Khambete posted 1 year 7 months ago

Development and its impact on the environment has long been a contentious issue in India, where lack of adequate monitoring and control mechanisms have led to severe degradation of land, water and forest resources. Mining activities in Goa have not only poisoned its land and water, but also affected livelihoods by negatively impacting agriculture, fisheries and forests.

Climate shocks and gender vulnerabilities in the Upper Ganga basin
Study points to vulnerabilities faced by women in the mountains and plains of Uttarakhand, which is likely to only increase with climate change. Amita Bhaduri posted 1 year 7 months ago

Socially constructed notions of the different roles and responsibilities of men and women have a huge bearing on access to and control over resources, and subsequently on their vulnerabilities. More often than not, this leads to vulnerabilities that are skewed towards women, more than men.

Mapping Pune’s aquifers
Groundwater use has doubled in Pune. Comprehensive mapping of groundwater resources and better management and governance is the need of the hour. Aarti Kelkar Khambete posted 1 year 8 months ago

Pune continues to face a water crisis every summer despite having sufficient water, thanks to its geographical location and plentiful natural water assets. While enough of its water needs are taken care of by water supply from the Khadakwasla dam, the use of groundwater to meet the needs of the population continues to increase.
