During the monsoon, temple tanks in Chennai fill to the brim with water, helping in groundwater recharge.

Besides showcasing the architectural expertise and aesthetics of their time, temple tanks also play an extremely important role as water storage systems in Chennai. Chennai has 39 temple tanks (excluding the suburban area) according to a study conducted in 2008.  As the rains arrived, a few temple tanks in the city were filled to the brim with water, thus helping in groundwater recharge while offering a spectacular view for devotees.

Mitul Baruah from Ashoka University narrates personal experiences of people affected by floods in Majuli, Assam.

Floods are an annual phenomenon in Assam. They are as integral to the state as the Brahmaputra River is, and each monsoon, we are reminded that Assam exists (or is drowning). As I write this piece, Assam is slowly recovering from the first wave of flood this monsoon.

Mangroves are carbon-dense ecosystems that can play an important role in carbon storage, study suggests.

Straddling land and sea and swarming with life, mangroves are key to healthy coastal ecosystems. They are recognised for their role as storm barriers, protecting coastal areas from flooding and erosion by dissipating the energy of huge waves. They act as nurseries for fish, help filter river water of pollutants and trap excess sediment before it reaches the ocean. Increasingly, mangrove protection and restoration is being acknowledged as a viable option for mitigating the effects of growing greenhouse gas emissions worldwide.

A study finds that selectively increasing coarse grains/millets in crop production can greatly help in reducing the negative impacts of climate shocks on future food production in India.

Crop production is highly influenced by the sensitivity of crops to variations in climate and can have major implications for food supply and rural livelihoods. The effects of climate change are increasing in India, where extreme rainfall events have become more frequent and spatially more variable. On the other hand, there has also been an increase in the severity and frequency of droughts.

The major cause of insufficient forest cover in India seems to be ruthless cutting of trees in the name of urbanization and development.

Van Mahotsava is an annual tree planting festival which was initiated by Shri Kulapati Kanaiyalal Munshi, the Union Minister for Agriculture and Food, Government of India, in 1950 to create awareness about the importance of trees and conservation of forests. Since then, this plantation drive has been bringing multitudes of people across the country towards the common goal of increasing green cover. The idea to organize such an annual event might have emerged after a national tree plantation drive in 1947 in which national leaders like Dr.
