International Day of Forests

A pond equals ten wells, a reservoir equals ten ponds. A son equals ten reservoirs, and a tree equals ten sons! -Matsya Purana

March 21 is the International Day of Forests. The Day celebrates and raises awareness of the importance of all types of forests. This year’s theme is ‘The Role of Forests in Ensuring Sustainable Production and Consumption’.

What is the water table and why is it important?

Water table is the boundary below which the soil is saturated with water. Above the water table is the unsaturated zone, which has water and oxygen, whereas below water table, groundwater fills any space between soil and rocks.

What is aquifer and examples?

Most groundwater, including a significant amount of our drinking water, comes from aquifers. Aquifers are a layer of rock or soil that can hold water. This is the precipitation that has seeped through the soil. In order to access this water, a well must be created by drilling a hole that reaches the aquifer. While wells are manmade points of discharge for aquifers, they also discharge naturally at springs and in wetlands. Aquifers are not underground rivers, but water contained in porous rock, soil or gravel.
