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 08:07 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.

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 07:10 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.

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 02:28 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).
