What Happened
- A study by the International Institute for Environment and Development (IIED) assessed food security across 162 countries using a climate-sensitive Food Security Index.
- India's baseline food security score of 5.31 is significantly below the global average of 6.74, placing it among the most vulnerable large economies.
- At 1.5°C of warming, India's score falls to 4.96; at 2°C, it drops further to 4.52 — a sharp decline with major implications for agricultural output and population welfare.
- The study's critical finding: economic growth alone cannot make food systems resilient to repeated climate stress — each $1,000 increase in per capita GDP correlates with only a 0.2-point improvement in food security score.
- Approximately 4.56 billion people (nearly 59% of humanity) currently live in countries scoring below the global average; at 2°C warming, an additional 291 million people could fall below this threshold.

The Four Pillars of Food Security
The concept of food security rests on four interconnected pillars, originally articulated at the 1996 World Food Summit and refined by the FAO. These pillars determine not just whether food is produced, but whether it reaches people in adequate quantities and nutritional quality.
- Availability: Sufficient quantities of food produced domestically or accessible through trade
- Accessibility: Physical and economic access to food at the household level — affordability, proximity to markets
- Utilization: Nutritional adequacy and the ability of the body to absorb nutrients (linked to health, water, and sanitation)
- Stability/Resilience: Consistent access across time, immune to shocks from climate events, price volatility, or conflict
Connection to this news: India scores particularly low on availability and sustainability/resilience pillars — the very pillars that climate change directly undermines through disrupted monsoons, heat stress on crops, and increased flood and drought frequency.
Climate Change and Indian Agriculture: Structural Vulnerabilities
India's agriculture sector covers roughly 140 million hectares and employs nearly 46% of the workforce, yet it is heavily dependent on the monsoon. Climate projections indicate rising temperatures will disrupt both kharif and rabi crop cycles, reduce water availability, and increase extreme weather events. Sub-Saharan Africa and South Asia face the sharpest projected declines in food security scores globally.
- India loses an estimated 1.5–2% of GDP annually due to climate-related agricultural losses
- Heat stress can reduce wheat yields by up to 6% per 1°C rise in mean temperature
- The Indo-Gangetic Plain — India's granary — is particularly exposed to groundwater depletion and rising temperatures
- National Action Plan on Climate Change (NAPCC) includes the National Mission for Sustainable Agriculture (NMSA) as one of its eight missions
Connection to this news: The IIED index specifically flags South Asia as facing among the steepest food security declines under warming scenarios, making India's vulnerability not just an agricultural issue but a national security concern.
Limits of GDP Growth as a Food Security Buffer
Classical development theory assumes that rising incomes automatically translate into improved food security through better purchasing power. The IIED study challenges this assumption: at higher income levels, gains in food availability and sustainability are disproportionately weak compared to gains in accessibility. This suggests the nature of growth matters as much as its magnitude — growth without agricultural resilience or diversified food systems does not adequately shield populations from climate shocks.
- High-income countries in the G7 also showed notable vulnerability — the United States faces larger projected losses than the United Kingdom
- At 2°C warming, food insecurity rises by an average of 22% in low-income countries but only 3% in high-income countries
- India's projected gap between economic growth and food security improvement points to structural weaknesses in agricultural infrastructure and rural supply chains
Connection to this news: This finding is critical for UPSC Mains (GS3/Essay): India's ambition to become a $5 trillion economy does not automatically resolve its food security challenge — targeted agricultural adaptation investment is necessary.
Paris Agreement and 1.5°C/2°C Scenarios
The Paris Agreement (2015) established the target of limiting global average temperature rise to well below 2°C above pre-industrial levels, with efforts to limit it to 1.5°C. These are not abstract scientific benchmarks — as the IIED study demonstrates, the difference between 1.5°C and 2°C translates into hundreds of millions of additional food-insecure people globally.
- Current Nationally Determined Contributions (NDCs) globally put the world on track for approximately 2.5–3°C of warming
- India's own NDC for 2035 targets 47% emission intensity reduction from 2005 levels
- The IPCC Special Report on 1.5°C (2018) documented that agricultural yields for crops like maize, rice, and wheat could decline significantly between the two warming scenarios
Connection to this news: The study directly uses these two Paris Agreement temperature thresholds as modeling scenarios, reinforcing why India's climate commitments and global climate ambition have direct food security consequences.
