Why is this in the news?

The International Fund for Agricultural Development (IFAD) released a report at COP31, highlighting that the ongoing El Niño event could lead to an estimated $11 trillion in global income losses over the next five to six years. The report, titled ‘Food Systems Under Stress: Building Resilience from the First Mile’, underscores the potential for severe food insecurity, particularly impacting small-scale farmers and vulnerable regions due to concurrent climate and economic shocks.

Background

  • The 2026-27 El Niño event is projected to peak between October 2026 and January 2027, with its effects on agricultural production and rural livelihoods potentially extending beyond 2027.
  • The report identifies a confluence of factors exacerbating the El Niño impact, including rising global temperatures, the 2026 energy price shock linked to the Strait of Hormuz crisis, and pre-existing climate stress in various regions.
  • Southern Africa, including Botswana, Namibia, South Africa, Zambia, and Zimbabwe, faces a high probability of agricultural drought, threatening maize production and water availability.
  • Rice-producing regions in South and Southeast Asia are also identified as highly vulnerable, with historical data from the 2015-16 El Niño showing significant reductions in regional rice output.
  • The World Food Programme (WFP) estimates, cited in the report, indicate that an additional 49 million people could experience acute food insecurity by the end of 2027.
  • Integrated interventions combining support for agricultural inputs, market access, and financial services are suggested to mitigate farmers’ income losses more effectively than financial interventions alone.

What is El Niño?

  • El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
  • It is the warm phase of the larger phenomenon known as the El Niño-Southern Oscillation (ENSO).
  • El Niño events typically occur every two to seven years and can last for nine to twelve months, though their impacts can persist longer.
  • This warming of ocean surface temperatures impacts atmospheric circulation, leading to significant changes in global weather patterns.
  • Common impacts include increased rainfall in parts of South America and the southern United States, and droughts in Australia, Indonesia, and parts of South Asia and Africa.
  • In India, El Niño is often associated with a weaker monsoon, leading to reduced rainfall and potential agricultural distress.
  • The opposite phase, La Niña, is characterized by unusually cold ocean temperatures in the eastern tropical Pacific, often bringing contrasting weather patterns.
  • The monitoring of sea surface temperatures, atmospheric pressure, and wind patterns is crucial for forecasting El Niño events and their potential global impacts.

Key Features

Feature Significance
El Niño Phenomenon A periodic climate pattern characterised by the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean, significantly influencing global weather patterns.
Global Income Losses The International Fund for Agricultural Development (IFAD) report projects potential global income losses of up to $11 trillion over the next five to six years due to El Niño’s impacts.
Food Insecurity Threat An estimated additional 49 million people could face acute food insecurity by the end of 2027, exacerbated by El Niño’s effects on agricultural production.
Agricultural Vulnerability Southern Africa faces heightened drought risks, while major rice-producing regions in South and Southeast Asia are particularly susceptible to reduced yields.
Compounding Shocks El Niño is developing amidst rising global temperatures and follows recent energy and fertiliser price shocks, intensifying stress on food systems.
Small-Scale Farmers These farmers, who produce a third of the world’s food, are disproportionately affected by increased production, processing, and transport costs.

Why it Matters

Economic Implications

  • The projected $11 trillion in global income losses underscores the severe economic disruption anticipated, impacting national GDPs and individual livelihoods worldwide.
  • Increased energy and fertiliser costs, coupled with reduced agricultural output, contribute to inflationary pressures and supply chain disruptions, affecting global trade and consumer prices.
  • The financial strain on small-scale farmers, who are critical for global food supply, could lead to reduced investments in agriculture and increased rural poverty.

Food Security and Livelihoods

  • The potential for an additional 49 million people to face acute food insecurity highlights a significant humanitarian crisis, necessitating robust international and national response mechanisms.
  • Disruptions to staple crop production, such as maize and rice, directly threaten food availability and accessibility, particularly in vulnerable regions.
  • Rural livelihoods, heavily dependent on agriculture, face substantial risks from crop failures and income reductions, potentially leading to increased migration and social instability.

Climate Change and Resilience

  • The confluence of El Niño with rising global temperatures accentuates the urgency of climate change adaptation and mitigation strategies.
  • The report’s emphasis on coordinated investments in farming, market access, and finance underscores the need for integrated approaches to build resilience in food systems.
  • Understanding and preparing for recurring climate phenomena like El Niño is crucial for long-term sustainable development and disaster risk reduction.

Global Governance and Cooperation

  • The IFAD report, released at COP31, highlights the interconnectedness of climate change, food security, and economic stability, necessitating multilateral cooperation and policy coherence.
  • The warning from IFAD, a UN agency, calls for coordinated international efforts to support vulnerable nations and communities in building resilience against climate shocks.
  • The discussion at COP31 provides a platform for member states to commit to and implement policies that address the multifaceted challenges posed by climate variability.

Challenges

1. Climate Variability and Extreme Weather Events

  • El Niño exacerbates existing climate stressors, leading to increased frequency and intensity of droughts, floods, and unpredictable rainfall patterns.
  • These extreme weather events directly impact agricultural productivity, leading to crop failures, livestock losses, and reduced water availability.

2. Food Price Volatility and Inflation

  • Reduced agricultural yields due to El Niño contribute to supply shortages, driving up food prices in domestic and international markets.
  • Increased energy and fertiliser costs further escalate production expenses, which are passed on to consumers, leading to food inflation and reduced purchasing power.

3. Rural Livelihood Vulnerability

  • Small-scale farmers, often operating with limited resources, are highly susceptible to income losses from crop failures and market disruptions.
  • The economic instability can lead to indebtedness, asset depletion, and a decline in overall rural welfare, potentially increasing poverty and food insecurity.

4. Supply Chain Disruptions

  • El Niño-induced weather anomalies can disrupt transportation networks, affecting the timely delivery of agricultural inputs and outputs.
  • Market access for farmers can be severely hampered, leading to post-harvest losses and reduced profitability, further stressing food systems.

UPSC Link: Supply Chain Management; Infrastructure

5. Acute Food Insecurity

  • The combined impact of reduced production, price volatility, and livelihood losses can push millions more into acute food insecurity.
  • Vulnerable populations, particularly in regions already experiencing climate stress, face heightened risks of malnutrition and humanitarian crises.
