Why is this in the news?

As of July 30, 2026, Andhra Pradesh has recorded a 52.4% rainfall deficit, with no district reporting normal rainfall, triggering concerns over agricultural output, water scarcity, and rural livelihoods. The deficit, exacerbated by the absence of significant monsoon activity despite a deep depression in the Bay of Bengal, has prompted calls for drought declarations and comprehensive relief measures. The situation underscores the vulnerability of rainfed agriculture in the state and the need for adaptive policy frameworks in the context of climate variability.

Background

• Andhra Pradesh is predominantly agrarian, with 60% of its net sown area dependent on rainfall, particularly in the Krishna and Godavari basins.
• The state receives 75% of its annual rainfall during the southwest monsoon (June–September), making deficits critical for kharif crops like paddy, groundnut, and pulses.
• The current deficit of 52.4% is among the highest in recent decades, surpassing the threshold for drought conditions as per the India Meteorological Department (IMD) classification.
• The El Niño-Southern Oscillation (ENSO) phenomenon has been linked to reduced monsoon rainfall in peninsular India, with a 60% probability of El Niño conditions persisting through 2026.
• Historically, Andhra Pradesh has declared droughts in 2015–16 and 2018–19, with the latter leading to the implementation of the Andhra Pradesh Drought Declaration Policy.
• The state’s water infrastructure, including major and medium irrigation projects like the Polavaram and Srisailam dams, is designed to mitigate short-term deficits, but prolonged dry spells strain storage levels.

What is Rainfall Deficit and How is it Classified?

• Rainfall deficit refers to the percentage shortfall in actual rainfall compared to the Long Period Average (LPA), calculated over a 50-year baseline by the IMD.
• IMD classifies rainfall as ‘deficient’ if it is 20–59% below LPA.
• A cumulative deficit of 25% or more across a meteorological sub-division (e.g., Coastal Andhra Pradesh, Rayalaseema) triggers drought-like conditions, necessitating state interventions.
• The deficit is monitored at the district level, with mandals (sub-district units) also tracked for localized drought declarations under the Andhra Pradesh Drought Declaration Policy.
• Rainfall data is sourced from the Directorate of Economics and Statistics (DES) and IMD’s Automatic Weather Stations (AWS) network, ensuring real-time updates.
• The deficit’s impact is assessed using the Standardized Precipitation Index (SPI), which quantifies meteorological drought severity over 1, 3, 6, or 12-month scales.
• Deficient rainfall disrupts the soil moisture regime, delaying sowing, reducing crop yields, and increasing pest incidences, particularly in rainfed regions.
• The deficit also affects groundwater recharge, with implications for drinking water supply and irrigation in the rabi season.

Key Features

Feature	Significance
Rainfall Deficit of 52.4%	Indicates severe hydrological stress, disrupting agricultural cycles, water availability, and socio-economic stability in Andhra Pradesh.
Districts with Large Deficit (Prakasam, East Godavari, Visakhapatnam, Annamayya, Chittoor)	High vulnerability in major agricultural and coastal districts, threatening kharif sowing and livelihoods.
El Niño Threat	Increases probability of prolonged deficient rainfall, compounding drought risks and necessitating adaptive agricultural and water management strategies.
Deep Depression over Bay of Bengal (Odisha/Chhattisgarh)	Shifts monsoon dynamics away from Andhra Pradesh, reducing rainfall prospects and exacerbating deficit conditions.
Surface Winds (40-50 kmph) in Coastal Andhra & Rayalaseema	Indicates high evaporation rates and potential for soil moisture loss, further stressing rainfed agriculture.

Why it Matters

Economic

• Disruption of kharif sowing cycle may reduce agricultural output, impacting GDP growth and rural incomes.
• Increased reliance on groundwater for irrigation raises long-term sustainability concerns and energy costs for farmers.
• Potential rise in food inflation due to reduced crop yields, affecting inflation targeting and monetary policy.

Agricultural

• Delayed or failed sowing in rainfed areas threatens food security and farmer livelihoods, particularly in districts like Prakasam and Chittoor.
• Livestock and dairy sectors face feed shortages, reducing productivity and income for marginal farmers.
• Increased pest and disease incidence in stressed crops due to suboptimal rainfall conditions.

Environmental

• Groundwater depletion accelerates, risking long-term water security and ecosystem degradation in aquifer-dependent regions.
• Reduced river flows and reservoir levels threaten hydroelectric power generation and urban water supply.

Social

• Migration pressures may rise as rural households seek alternative livelihoods due to crop failures.
• Increased indebtedness among farmers due to higher input costs (e.g., diesel for groundwater pumping) and lower yields.

Challenges

1. Agricultural Drought and Crop Failure

• Failure of kharif sowing in rainfed areas may lead to zero or minimal yields, threatening food security.
• Livestock mortality and reduced milk production due to fodder shortages in deficit districts.

Prelims Practice Questions

Q1. Consider the following statements regarding rainfall classification by the India Meteorological Department (IMD):
1. Normal rainfall is defined as rainfall within ±19% of the Long Period Average (LPA).
2. Deficient rainfall is defined as rainfall between 19% below and 59% below the LPA.
3. Large deficient rainfall is defined as rainfall below 59% of the LPA.
4. Excess rainfall is defined as rainfall above 20% of the LPA.
How many of the above statements are correct?

1. Only one
2. Only two
3. Only three
4. All four

Answer: Only three — Statements 1 and 4 are correct. Statement 2 is incorrect because deficient rainfall is defined as between 19% and 59% below the LPA, while statement 3 is incorrect because large deficient rainfall is defined as below 59% of the LPA (not ‘below 59% of the LPA’).

Q2. Assertion (A): The South-West Monsoon in India is primarily influenced by the El Niño-Southern Oscillation (ENSO) phenomenon.
