A warming Pacific can reshape weather, economies and livelihoods, revealing the growing links between climate risk and development.
The Global Climate Traveler
El Niño may begin in the Pacific Ocean, but its consequences are felt across the world. For India, it is not merely a question of rainfall but a challenge that affects livelihoods, food prices, public health and economic resilience. Recent forecasts have renewed concerns about El Niño's return. The US National Oceanic and Atmospheric Administration (NOAA) has indicated a high probability of El Niño conditions developing during 2026, while the India Meteorological Department (IMD) has projected below-normal monsoon rainfall. Yet the real challenge lies not in rainfall statistics but in what climatic uncertainty does to a climate-vulnerable economy. In a world already experiencing record temperatures and mounting climate extremes, El Niño can intensify heatwaves, water stress and economic vulnerability. As UN Secretary-General António Guterres observed, “El Niño conditions will pour fuel on the fire of a warming world.”
The significance of El Niño extends far beyond India. Its effects are felt across continents through shifting weather patterns, disrupted food systems and economic uncertainty. Drought conditions often intensify in parts of Australia and Southeast Asia, while sections of South America may experience excessive rainfall and flooding. Marine ecosystems can also come under stress through coral bleaching and disruptions to fisheries. In an interconnected global economy, such disruptions rarely remain local. Climate shocks increasingly influence agricultural production, commodity prices and supply chains, with consequences for food security and inflation across countries. India therefore experiences only one part of a broader global climate challenge.
The Heat Economy
The economic effects of El Niño are often transmitted through heat stress. Rising temperatures reduce labour productivity in sectors dependent on outdoor work, while increasing health-related vulnerabilities among workers. Informal and daily wage labourers face the greatest exposure because they possess limited social and financial protection. The consequences extend beyond individual incomes. Heat-related illnesses place additional pressure on health systems, while productivity losses affect economic activity more broadly. Climate shocks therefore increasingly influence labour markets, public health and household resilience, particularly among vulnerable populations.
The Coming Water Economy
El Niño also highlights India's growing water vulnerability. Nearly half of the country's net sown area remains dependent on rainfall, making agriculture highly sensitive to monsoon variability. Uncertain rainfall affects sowing decisions, raises irrigation costs and increases dependence on groundwater, particularly for small and marginal farmers. The challenge extends beyond agriculture. As the world's largest user of groundwater, India faces increasing pressure on aquifers, reservoirs and urban water systems. Water stress can affect agricultural output, industrial activity and urban service delivery. El Niño therefore does not merely threaten rainfall; it exposes the risks of managing development in a water-constrained future. Water security is increasingly becoming an economic and governance challenge.
From Climate Shock to Kitchen Inflation
Food markets often serve as the first point of transmission between climate shocks and everyday life. Weather-related disruptions in agricultural production can tighten supplies of essential commodities, particularly vegetables, pulses and edible oils, creating inflationary pressures across the economy. For households, especially poorer ones, climate stress is often experienced through rising food bills rather than rainfall statistics. This places policymakers in a difficult position. Climate shocks can simultaneously slow economic activity and push up prices, linking environmental uncertainty with broader concerns of food security, inflation management and macroeconomic stability. As a result, climate risk is increasingly emerging as an economic challenge as much as an environmental one.
The Inequality Multiplier
Climate shocks do not affect all sections of society uniformly. Their impact depends on access to resources, infrastructure and adaptive capacity. Households with better housing, reliable water supply and financial security are generally better positioned to cope with climatic disruptions than vulnerable groups dependent on climate-sensitive livelihoods. As a result, El Niño can deepen existing developmental challenges related to income security, health and access to basic services. Similar disparities are visible globally, where countries with limited adaptive capacity often face greater climate risks. Climate resilience, therefore, is increasingly becoming an important component of inclusive development.
India's Adaptation Challenge
Climate shocks can no longer be viewed solely through the lens of disaster management. Strengthening resilience requires wider implementation of Heat Action Plans, climate-sensitive urban planning, groundwater conservation and efficient water-use practices. Initiatives such as the National Mission for Sustainable Agriculture, Pradhan Mantri Krishi Sinchayee Yojana and Atal Bhujal Yojana are important steps towards climate adaptation. Equally important are social protection measures, public health preparedness and livelihood support for vulnerable populations. Climate adaptation must increasingly move from the margins of environmental policy to the centre of development planning. Climate risks need to be integrated into urban planning, agricultural policy, water governance, public health systems and fiscal decision-making. Resilience is no longer solely an environmental objective; it is an economic and governance imperative.
The Development Imperative
El Niño reminds us that development and climate can no longer be viewed as separate policy domains. What makes the present moment different is that El Niño is returning to a world that is already warmer, more urbanised and more economically interconnected than before. A warming climate is reshaping questions of water security, urban planning, agricultural sustainability and public health. The challenge before India is not simply managing the next climatic disturbance but building institutions and systems capable of absorbing recurring environmental shocks. In that sense, El Niño is less a weather event than a test of the resilience and adaptability of India's development model.
