Phase IFoundation

Background

Overview

Directly impacts India's food security, farmer livelihoods, water resource management, and macroeconomic stability. Understanding its causes and consequences is vital for policy formulation and disaster preparedness.

The Indian Monsoon, a seasonal wind system, is crucial for India's agriculture and water security, contributing to about 70% of the country's annual rainfall. Variability in its onset, intensity, and distribution directly impacts agricultural output, reservoir levels, and the overall economy, often leading to conditions like drought or floods.

Facts & tables

Key facts

Agricultural Impact

Delayed or deficient monsoon leads to reduced sowing (e.g., food crops at 26% sowing coverage in North Karnataka), impacting crop yields and food security.

Water Resources Impact

Critically low reservoir levels (e.g., Almatti at 2.4% of total capacity, Tungabhadra at 9.283 tmcft against 105.788 tmcft capacity), affecting irrigation, drinking water, and power generation.

Socio-Economic Consequences

Causes reduced farmer income, potential for increased rural-urban migration, and rising food costs.

Climatic Factors

Linked to global climatic phenomena like El Nino and other factors such as reduced African sea winds.
