The Cauvery - dammed and fractured
Inspite of the realisation that minimum flows are essential for rivers to maintain their health and biodiversity, water released from various dams in India continues to disregard minimum environmental flow requirements. Posted on 23 Nov, 2022 03:58 PM

India is a dammed country. According to the National Registry for Large Dams (NRLD), in 2016 a total of 4877 dams were built in India and 313 dams were still under construction.

Wheat sowing dates influences yields in Eastern Gangetic Plains
Study indicates that better management of the annual cropping calendar can pay dividends for food security Posted on 01 Nov, 2022 08:56 AM

Wheat is a principal crop staple in South Asia with current cultivation extending across 36.1 million ha; around 73% of this area is in India where wheat provides approximately 21% of the aggregate food energy and 17% o

Greater adjustments to the annual cropping calendar are anticipated to increase wheat yield potential by an average of 0.84 t/ha (Image: Pixnio)
Assessing Udaipur’s groundwater reserves
A study using geospatial techniques suggests the need to regulate groundwater abstraction for long-term sustainability of groundwater use Posted on 29 Oct, 2022 03:04 PM

Population increase has placed ever-increasing demands on the available groundwater resources, particularly for intensive agricultural activities.

What causes tropical cyclone driven floods in India?
In the Indian region, landfalling tropical cyclones have the potential to cause floods in the river basins. Both tropical cyclone rainfall and antecedent soil moisture of the basin controls the severity of floods. Posted on 22 Oct, 2022 05:40 PM

Tropical cyclones are intense circular storms that originate over tropical oceans and are among the most significant threats to human life and property in the world. Tropical cyclones are associated with heavy rainfall and strong winds, which cause hazards such as storm surges and inland flooding.

Groundwater prospective zones in Bundelkhand
Integrating geographical information systems and remote sensing for delineation of groundwater potential zones in Bundelkhand region Posted on 22 Oct, 2022 02:59 PM

In the Bundelkhand craton region, groundwater is the primary source of drinking water. Due to low rainfall, agriculture mainly depends on the goundwater supply, which comes through bore wells. Most of the time, the region faces a water crisis during the summer season as the wells and tube wells go dry.

Numerous studies have been performed worldwide in which remote sensing data is used to delineate the groundwater potential zones (Image: India Water Portal Flickr)

Role of MGNREGA in the year after the 2020 lockdown: Survey findings from Bihar, Karnataka, Maharashtra, and Madhya Pradesh Posted on 22 Oct, 2022 09:33 AM

As the Covid-19 pandemic fades from media headlines and public consciousness, it is important to ensure that lessons learned are not forgotten.

Minimising the impact of floods: The role of income and governmental response
This study finds that higher income states are better placed to invest in flood precautionary measures as compared to low income states. Government expenditure on flood risk mitigation continues to be inadequate in India and needs to increase. Posted on 20 Oct, 2022 02:27 PM

India is one of the most flood-affected country following China and floods account for 53 percent of the disasters followed by cyclones (21 percent), landslides (10 percent), cold waves (6.4 percent), earthquakes (4.2 percent), and droughts (2 percent).

Invisible informal groundwater markets
While informal groundwater markets cater significantly to the needs of smallholder farmers in India, they continue to be unacknowledged and understudied. Posted on 17 Oct, 2022 12:55 PM

India is the largest user of groundwater globally and as high as 85 percent of water is used for irrigation. Groundwater extraction started with the green revolution that increased  food security and reduced poverty. However, it gradually led to drastic depletion in groundwater levels.
