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.

Urban flooding in Gujarat has led to some strange developments in recent weeks.

The videos were all over the Internet and social media. Expectedly so, because you don’t often see crocodiles swimming in flooded urban streets, sneaking up on strays. But that’s precisely what happened shortly after news of ‘urban floods’ in Vadodara hit headlines in early August. The city witnessed scary flash floods following spells of intense rain, bringing back memories of what the city had witnessed in June 2005 and then again in the monsoon of 2014, the latter perhaps leading to the coinage of the phrase ‘urban floods’.

Mobile agri-advisory services provide timely and relevant advice to farmers. But do they translate to practice in the field?

Agricultural extension and advisory services facilitate the transfer of knowledge, information, improved technologies and practices to farmers, farmer organizations and market actors. Research has shown positive effects of extension access when it came to knowledge, adoption, productivity, and economic returns for farmers. The high cost associated with face-to-face extension constrains effective service delivery to farmers, who are often widely distributed spatially.

A research paper argues that quick fix solutions to drought management will not work unless they are backed up by proper planning, implementation, monitoring and regulation of water use.

Maharashtra is reeling under drought this year too, with the situation in Marathwada particularly bad. As high as twenty four out of thirty six districts in the state are facing deficient monsoons and about 4,920 villages and 10,506 hamlets are now completely dependent on water tankers for drinking water.
