Opening

The gangetic valley, a fertile zone, is a major food belt of India. ≈ 90% groundwater is used for agriculture in this region.

groundwater potential is on a decline - causes:

Body · points

(1.) Contamination eg. Uranium levels very high in Bihar, & west Bengal (2.) overuse of groundwater Eastern India - region with high number of critical units i.e. 90% to >100% use (CGWB). (3.) Population density very high eg. U.P., Bihar, west Bengal

(4.) Poor integrated water management. eg. only 32% water (rainfall) is harvested in India

(5.) Hardrock plateaus eg. Madhya Pradesh region

(6.) Rapid concretization & deforestation support urbanization eg. in uttrakhand

(7.) Heavy siltation → lower rejuvenation ability of groundwater eg. near Farakka barrage.

Impact on food security

(1.) Water decline → less water availability for cropping (Input unavailability) → decline in food availability

(2.) Increased pressure on surface water → Drinking & sanitation water crisis → health problems → reduced nutrient absorption.

(3.) Interstate conflicts will rise → instability → agriculture productivity stagnated

(4.) Use of contaminated ground water → nutritional deficiency

Way forward

(1.) Rainwater harvesting is indispensible (2.) Interstate coordination for rejuvenation planning.
