  WHY IS IT IN NEWS?

 

As per The Hindu, India is set to receive below-normal rainfall in July — the deficit has already touched ~40% in the early part of the month, a spell IMD classifies as ~~Deficient~~.

 

Since July is the most crucial month of the Southwest Monsoon, a prolonged deficit can hit agriculture, water availability, power generation, inflation, and overall economic growth. This matters because ~~55% of India’s net sown area~~ is still rain-dependent despite irrigation expansion.

📊  IMD RAINFALL CLASSIFICATION (VS LPA)

 

 

 

Large Excess

+60% or more

Excess

+20% to +59%

Normal

−19% to +19%

Deficient  ← current status

−20% to −59%

Large Deficient

−60% or below

 

⚠️  Key Takeaway

•  A 40% shortfall places the current spell squarely in the ~~Deficient~~ category — the second-most severe classification on the IMD scale.

 

 

🗓️  WHY JULY RAINFALL MATTERS

 

July is the backbone of India’s agricultural calendar. It determines:

●  Sowing of Kharif crops

●  Groundwater recharge

●  Reservoir storage

●  Drinking water availability

●  Hydroelectric power generation

●  Rural income & food production

●  Inflation trajectory

 

💡  Remember

•  Even if rainfall improves later, ~~delayed sowing often reduces yields~~ — timing matters as much as total volume.

 

 

  WHY HAS RAINFALL TURNED DEFICIENT?

 

●  Weak Monsoon Trough — remains north / shifts away from ideal position, cutting rainfall over central India

●  Break Monsoon Conditions — the monsoon weakens for several days, causing dry spells over large areas

●  Madden-Julian Oscillation (MJO) — a moving tropical cloud/rainfall system; its unfavourable phase suppresses Indian rainfall

●  Indian Ocean Conditions — sea-surface temperature & circulation patterns influence moisture transport

●  Climate Change — rising temperatures increase extreme rainfall events, long dry spells, and irregular monsoon distribution

 

 

🌾  IMPACT ON AGRICULTURE

 

▍ Delayed Sowing

●  Farmers delay sowing of rice, soybean, cotton, pulses, and maize

▍ Lower Crop Yield

●  Insufficient soil moisture hurts germination and crop growth

▍ Increased Cost

●  Extra irrigation, diesel pumps and fertilizers raise cultivation costs

▍ Crop Failure

●  Continued dry spells can cause ~~significant crop losses~~

 

 

💧  IMPACT ON WATER RESOURCES

 

●  Reduced reservoir storage and groundwater recharge

●  Falling levels in rivers and lakes

●  Stress on urban water supply

🚱  Watch Out

•  Many cities may face ~~drinking-water shortages~~ if reservoirs aren’t adequately replenished before withdrawal.

 

 

📉  IMPACT ON ECONOMY & INFLATION

 

▍ Economy

●  Lower agricultural output → reduced rural purchasing power

●  Lower FMCG demand → slower GDP growth

●  Higher government expenditure on relief measures

▍ Inflation

●  Food inflation rises from lower output of vegetables, pulses, cereals, fruits

●  Higher food prices may force the ~~central bank to stay cautious on interest rates~~

 

 

⚡  IMPACT ON ENERGY & ENVIRONMENT

 

▍ Energy

●  Hydroelectric generation declines with lower reservoir inflow

●  Thermal power demand rises → higher coal consumption & emissions

▍ Environment

●  Reduced groundwater recharge; higher forest-fire risk

●  Drying wetlands, biodiversity stress, wildlife migration, soil degradation

 

🌱  Silver Lining — Deficit ≠ Drought

•  Efficient water management and improved irrigation planning

•  Better adoption of micro-irrigation

•  Promotion of drought-resistant crops

•  Rising public awareness of water conservation

 

 

🏛️  GOVERNMENT MEASURES

 

 

 

IMD

Monsoon forecasting, early warning systems, weather advisories

Ministry of Agriculture

Crop advisories, contingency crop plans, seed distribution

PM Fasal Bima Yojana (PMFBY)

Insurance support against weather-related crop losses

PM Krishi Sinchai Yojana (PMKSY)

Drip & sprinkler irrigation — ‘Per Drop More Crop’

Jal Shakti Abhiyan

Water conservation, rainwater harvesting, groundwater recharge

 

 

🚧  PERSISTING CHALLENGES

 

●  High dependence on rain-fed farming

●  Depleting groundwater tables

●  Low irrigation coverage in several regions

●  Climate uncertainty & erratic rainfall patterns

●  Fragmented landholdings

●  Limited crop diversification

 

 

🚀  WAY FORWARD

 

●  Improve Irrigation — expand micro-irrigation, canal networks, solar pumps

●  Climate-Resilient Agriculture — drought-resistant seeds, crop diversification, millets, pulses

●  Strengthen Weather Forecasting — improve village-level advisories

●  Water Conservation — rainwater harvesting, watershed development, aquifer recharge

●  Better Reservoir Management — integrated river-basin planning

●  Farmer Awareness — scientific, forecast-based sowing decisions
