Key Issues Affecting Food Security: From Agriculture to Climate Change

India produces enough food to feed its 1.4 billion people, yet nearly 195 million Indians go to bed hungry each night. This paradox sits at the heart of the food security debate. The country ranks among the world’s top producers of milk, wheat, rice, and pulses, but it also ranked 105th out of 127 countries on the 2024 Global Hunger Index with a score of 27.3. The reasons stretch far beyond simple shortages. They involve how we grow food, who grows it, the climate we grow it in, and the systems that move food from farm to plate. Let us unpack the key issues shaping food security today.

Agricultural challenges shaping food production 🔗

Agriculture is the backbone of food security, but the sector faces structural problems that limit how much it can produce and how reliably it can do so. With agriculture employing nearly half of the country’s workforce and supporting the livelihoods of over 650 million rural residents, any weakness in the system directly translates into weaker food security.

Shrinking and fragmented land holdings 🔗

Cultivable land is shrinking even as the population grows. Urban expansion, industrial use, and soil degradation are eating into farmland. To make matters worse, land is fragmented across generations through inheritance. The average Indian farm size has fallen to roughly one hectare, making it difficult for farmers to invest in machinery, irrigation, or modern inputs. Small and marginal farmers, who form over 85 percent of the farming community, cannot achieve the economies of scale needed for profitable production. Fragmented land holdings, inadequate irrigation, and limited access to credit and technology together keep productivity well below the country’s potential.

Labour supply and rural distress 🔗

Agricultural labour is in a strange position. There is a shortage of skilled labour in many regions because young people are migrating to cities in search of better-paying, less risky work. At the same time, a large pool of underemployed labour exists in the off-season. Women, who carry out a significant share of farm work, are paid less than men for the same tasks. According to research, female workers in the rural non-agriculture sector earn only about 65 percent of male wages, which weakens household purchasing power and food access.

Input availability and rising costs 🔗

Seeds, fertilizers, pesticides, irrigation water, and credit are the basic inputs farmers need. Yet, access remains uneven. High-yielding seeds and modern equipment are concentrated in irrigated regions like Punjab, Haryana, and western Uttar Pradesh, while rain-fed regions in eastern and central India are starved of investment. Rain-fed agriculture still accounts for about 65 percent of cultivated land, which means most farmers are at the mercy of the monsoon. Fertilizer prices, dependent on global markets and crude oil, have grown volatile, squeezing margins for already cash-strapped farmers.

Government policies and the procurement puzzle 🔗

Government policy has a powerful effect on what gets grown and where. The Minimum Support Price (MSP) system, designed to protect farmers, has unintentionally pushed cultivation towards rice and wheat at the cost of pulses, oilseeds, and millets. This has skewed diets, depleted groundwater in north-western states, and reduced soil fertility. The Public Distribution System, Mid-Day Meal Scheme, and MGNREGA have expanded access to food, but issues like leakages, exclusion errors, and identification problems in the Targeted PDS continue to limit how well subsidies reach the truly needy.

Climate change and the future of farming 🔗

If agriculture sets the stage, climate change is rewriting the script. The country is among the most vulnerable to climate impacts because so much of its food production depends on predictable weather and abundant water.

Erratic monsoons and extreme weather 🔗

The monsoon, which feeds most of the country’s farmland, is becoming harder to predict. Heat waves, unseasonal rainfall, and prolonged dry spells are now common. The World Bank has projected that for a 4°C global warming scenario, India could see a 10 percent increase in annual mean monsoon intensity and a 15 percent rise in year-to-year monsoon variability. Droughts in the north-west and excess rainfall in the south are already disturbing established crop calendars.

The yield impacts are alarming. Studies have found that rising temperatures could cut rice yields by 10 to 40 percent, wheat by 2 to 10 percent, maize by 2 to 12 percent, and sorghum by 10 to 12 percent. Wheat production in Punjab, Haryana, and Uttar Pradesh, the country’s grain bowl, faces a projected decline of 10 to 20 percent without strong adaptation measures.

Greenhouse gases and the agriculture paradox 🔗

Agriculture is both a victim and a contributor to climate change. Methane from paddy fields and livestock, nitrous oxide from fertilizers, and carbon dioxide from machinery and land-use changes add to greenhouse gas emissions. Higher temperatures, in turn, drive more pest outbreaks, lower nutrient content in crops, and reduce milk yields in heat-stressed cattle. This creates a vicious circle where production methods worsen the climate problem that is hurting production.

Water scarcity and groundwater depletion 🔗

Water is perhaps the most stressed resource in food production. The country uses over 80 percent of its extracted groundwater for irrigation, and aquifers in major farming states are dropping at alarming rates. Climate change worsens this through higher evaporation, erratic recharge cycles, and contamination from flooding. Rivers, dams, streams, and groundwater resources are all under stress, and as freshwater dwindles, the cost of irrigation rises, hitting small farmers the hardest.

The Sundarbans region offers a stark example. Repeated cyclones such as Amphan and Yaas have pushed saline seawater into farmland, turning fertile paddy fields fallow and crippling local food production.

Innovation, infrastructure, and the missing links 🔗

Producing food is only half the battle. Moving it efficiently from farm to plate is where many of the country’s hardest-to-fix problems lie. A field of healthy produce means little if it rots before reaching a market.

Post-harvest losses: a silent crisis 🔗

India loses a staggering amount of food after harvest. A NABCONS study estimated annual losses of about 22 percent of foodgrain output, or roughly 74 million tonnes worth over ₹1.5 lakh crore. For fruits and vegetables, losses can run as high as 25 to 30 percent of total production. This wastage is enough to feed millions, which makes post-harvest loss reduction one of the fastest ways to boost food security.

The losses occur at every stage. Damage happens in farmers’ fields, during packaging, in transportation, and at the marketing stage, with transport and marketing accounting for the largest share. Heaps of tomatoes, onions, and leafy greens spoiling on open trucks under the sun are a familiar sight on rural highways.

The cold chain gap 🔗

Cold storage is one of the most important pieces of infrastructure missing in much of the country. Although the country operates over 8,800 cold storages with a capacity of about 40 million metric tonnes, capacity is unevenly distributed and largely tied to potato storage. The real shortage lies in supporting infrastructure: pre-cooling units at farm gates, reefer trucks for transport, and pack-houses. A National Centre for Cold-chain Development report flagged that the gap in reefer vehicles stood at 85 percent, pack-houses at 99 percent, and ripening chambers at 91 percent. Without these, even strong cold storage networks cannot prevent spoilage.

Operating costs add another layer of difficulty. Indian cold storage units spend roughly twice as much per cubic metre as their Western counterparts, with energy expenses accounting for about 28 percent of operating costs compared to 10 percent in the West. This makes private investment in cold chains commercially difficult.

Technology, digitization, and smart agriculture 🔗

Innovation offers real promise. Precision farming, satellite-based crop monitoring, drone-led pesticide application, and digital warehouse management systems are being adopted by progressive farmers. The Pradhan Mantri Kisan Sampada Yojana now aims to create end-to-end cold chains from farm gate to retail outlet, integrating pre-cooling, processing, and refrigerated transport. Digital dashboards and Internet of Things sensors are being piloted to monitor humidity and temperature remotely, helping reduce wastage in warehouses.

Computerization of Primary Agricultural Credit Societies and modern steel silos managed by the Food Corporation of India are also expanding decentralized storage. These reforms matter because they shorten the leaky pipeline between production and consumption.

Sustainable practices and crop diversification 🔗

Going forward, no single fix will work. The country must combine climate-resilient seeds, sustainable irrigation methods like drip and sprinkler systems, integrated pest management, and crop diversification away from water-thirsty rice and wheat. The renewed national push for millets, often called nutri-cereals, is one such step. Millets need less water, tolerate heat better, and are more nutritious, making them well-suited for a warming climate and a malnourished population.

Connecting the dots 🔗

The issues affecting food security are tightly interlinked. Shrinking farms feed into low productivity, low productivity feeds into rural poverty, rural poverty feeds into out-migration, and out-migration weakens the labour base for agriculture. Climate change layers stress on top of all this, while weak infrastructure ensures that whatever is produced is not fully delivered. Tackling food security therefore needs simultaneous action on farms, in policy rooms, in research labs, and in supply chains. A focus on only one area, however well-intentioned, simply shifts the bottleneck elsewhere.

What do you think? If you had to choose between investing more in climate-resilient farming techniques or building better cold chain infrastructure to address food insecurity, which would you prioritize and why? And how can young consumers like college students help reduce food waste in their everyday lives to ease the pressure on this system?
