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! Aarti Kelkar Khambete posted 1 month 3 weeks ago

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.

Cereals drain India dry
A study on virtual water flows in interstate trade of cereals in India shows that cereals are rapidly draining the states that have the most critical levels of groundwater. Aarti Kelkar Khambete posted 3 months ago

Agricultural stagnation and inefficient irrigation systems

Agriculture continues to be an important sector for the Indian economy and for food security with more than half of the workforce being employed in agricultural activities. Greater use of improved crop varieties, irrigation and fertilisers have contributed to major improvements in crop yields in India.
