Does a drop per crop help groundwater extraction to stop?
This World Bank study from Andhra Pradesh found that drip irrigation did not limit groundwater exploitation. Farmers who had saved water continued to draw groundwater and sell it to farmers who were water constrained. Aarti Kelkar Khambete posted 3 weeks 2 days ago

Groundwater irrigation covers more than half of the total irrigated area in India and is responsible for 70 percent of the agricultural production, making India one of the largest users of groundwater in the world.

Global warming can spell doom for India's freshwater fish!
Climate change is warming river waters and changing their flows. These changes can spell doom for fish that live in these waters. Aarti Kelkar Khambete posted 1 month ago

Freshwater ecosystems such as rivers, lakes, ponds cover only 0.8 percent of the Earth’s surface, but are incredibly biodiverse. They harbour around ~15,000 fish species, corresponding to approximately half of the global known fish.

Human activities such as water abstraction, diversion, damming, and pollution are posing a threat to the survival of fish.

Shrinking forests, declining biodiversity - a ticking time bomb!
A fatal tick borne disease is on the rise in the Western Ghat states. Deforestation, declining biodiversity and increasing human animal conflicts are to blame. Aarti Kelkar Khambete posted 1 month ago

The Western Ghats region of South India is one of the world's most important biodiversity hotspots, and the rainforests of this region are known to harbour 500 types of bird species, 225 reptile species, 219 amphibian species, and 133 mammal species.

Uranium in drinking water: A growing concern for India
A recent report by CGWB reveals that uranium contamination of groundwater is on the rise with Punjab and Haryana being the most affected. Aarti Kelkar Khambete posted 1 month 2 weeks ago

Groundwater continues to be extracted at frightening proportions in India and the fear of severe depletion of groundwater resources in the coming years is real. As if this is not enough, the available groundwater is also deteriorating in quality posing a severe threat to the health of the population.

Poisoned waters, deadly outcomes!
A study shows that high arsenic contamination of groundwater in Bihar is linked with increase in cancer cases. Districts located near the Himalayan river basins have more people with cancer. Aarti Kelkar Khambete posted 1 month 4 weeks ago

While groundwater is an important source of drinking water worldwide, contamination of groundwater sources is on the rise. Arsenic contamination of groundwater has been found to affect as high as 300 million people worldwide exposing them to a number of health risks.

Poisonous encounters: Nitrate contamination of groundwater in Rajasthan
This study from Rajasthan found that anthropogenic factors led to nitrate contamination of groundwater. High nitrate levels in drinking water posed major health risks to children. Aarti Kelkar Khambete posted 2 months ago

Groundwater in arid and semi arid regions continues to be a valuable and often the single most source of freshwater and conservation of this resource remains crucial for the survival of communities residing in the area. At the same time, a serious decline in the quality of groundwater is adding pressure on these water resources.
