Quick Revision: Andhra Pradesh’s 52.4% rainfall deficit by July-end 2026, driven by El Niño and suppressed monsoon activity, threatens kharif crops, water resources, and necessitates urgent policy interventions including drought declarations and farmer support.

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 resource management, and potential drought conditions. The India Meteorological Department (IMD) has forecasted minimal rainfall until August 3, exacerbating the crisis, while the state government faces calls to declare drought-hit mandals and initiate relief measures.

Background

• Andhra Pradesh, a predominantly agrarian state, relies heavily on the Southwest Monsoon (June–September) for agricultural activities, with 60% of its net sown area being rainfed.
• The state’s average annual rainfall is approximately 930 mm, with Coastal Andhra Pradesh and Rayalaseema regions receiving 1,000–1,200 mm and 600–800 mm respectively.
• The Southwest Monsoon contributes 75–80% of the state’s annual rainfall, critical for kharif crops such as paddy, groundnut, and pulses.
• El Niño conditions, associated with suppressed monsoon rainfall over India, have been a recurring concern in recent years, including 2023–2024, which saw widespread droughts in several states.
• The IMD classifies rainfall as ‘normal’ if it is within ±19% of the Long Period Average (LPA); ‘deficient’ if between -20% and -59%; and ‘large deficient’ if below -60%.
• The state government’s response includes directives for comprehensive support to farmers and potential mandal-level drought declarations, as advocated by political parties like the CPI.

What is Rainfall Deficiency and its Implications?

• Rainfall Deficiency: A deviation of actual rainfall from the Long Period Average (LPA), measured as a percentage. Deficiency above 20% is classified as ‘deficient,’ while below -60% is ‘large deficient.’
• Southwest Monsoon: The primary source of rainfall for Andhra Pradesh, critical for kharif sowing and reservoir replenishment. Its variability is influenced by global phenomena like El Niño and La Niña.
• El Niño-Southern Oscillation (ENSO): A climate pattern where warming of the Pacific Ocean (El Niño) suppresses monsoon rainfall over India, while cooling (La Niña) enhances it. The 2026 monsoon season has been impacted by El Niño conditions.
• Agricultural Impact: Rainfed agriculture in Andhra Pradesh is highly vulnerable to monsoon failures. Paddy, the state’s staple crop, requires 1,200–1,500 mm of water, making it particularly susceptible to rainfall deficits.
• Water Resource Management: Deficient rainfall reduces reservoir storage, groundwater recharge, and river flows, exacerbating water stress for irrigation and drinking purposes. Major reservoirs like Srisailam and Nagarjunasagar are likely to witness reduced inflows.
• Drought Declaration: The Andhra Pradesh government may declare drought-hit mandals under the National Disaster Management Authority (NDMA) guidelines, enabling relief measures such as input subsidies, waivers, and employment generation schemes.
• IMD Forecasting: The IMD provides short-range and long-range forecasts, including weekly and monthly outlooks, to aid agricultural planning and disaster preparedness. Its predictions are based on dynamic models and satellite data.
• Policy Responses: States adopt measures such as crop insurance (PMFBY), water conservation techniques (micro-irrigation, farm ponds), and alternative cropping patterns (short-duration varieties) to mitigate monsoon failures.

Key Features

Feature	Significance
Rainfall Deficit of 52.4% by July-end	Indicates severe meteorological drought, disrupting agricultural cycles and water availability for kharif sowing.
Uniform Deficiency Across All Districts	Contrasts with normal rainfall in NTR and SPSR Nellore earlier, now showing significant deterioration.
IMD Forecast of No Rain Until August 3	Exacerbates soil moisture stress, delaying sowing and increasing risk of crop failure.
Strong Surface Winds (40-50 kmph)	Accelerates evapotranspiration, worsening moisture deficit in already stressed soils.
Deep Depression Over Bay of Bengal	Expected to bring rainfall to Odisha and Chhattisgarh, leaving Andhra Pradesh largely untouched.
