Food Loss & Waste – Causes & Consequences – Explained Pointwise

Observed annually on 29 September, the International Day of Awareness of Food Loss and Waste highlights the need to reduce food lost along supply chains and food wasted at retail, food-service and household levels. Food loss & waste remain one of the world’s most persistent challenges, with severe consequences for climate, food security, economic cost, and sustainable use of natural resources.

What is food loss and food waste?

• Food loss refers to the decrease in the quantity or quality of food before it reaches the consumer, mainly during production, harvesting, post-harvest handling, storage, processing and transportation.
• Food waste refers to food that is discarded or left uneaten at the retail, food-service and household levels, even though it was fit for human consumption.
• Food loss occurs mainly along the food supply chain before retail, while food waste occurs mainly at the retail, food-service and consumer levels.

What is the present status of food loss & waste in India & globally?

What are the major causes of food loss and waste in India?

1. Inadequate storage infrastructure: Inadequate and unevenly distributed warehouses, silos, cold-storage facilities and scientific storage systems contribute significantly to post-harvest food losses in India. Perishable commodities such as fruits, vegetables, dairy and fish are particularly vulnerable to spoilage when appropriate temperature and humidity-controlled storage is unavailable. This leads to quality deterioration, distress sales, lower farmer incomes and wastage of edible food.
2. Weak cold-chain infrastructure: India has gaps in integrated cold-chain infrastructure connecting farms, collection centres, storage facilities, refrigerated transport and markets. Inadequate pre-cooling, insufficient refrigerated transportation and uneven distribution of cold-storage facilities can increase post-harvest spoilage and quality deterioration, leading to economic losses for farmers and reduced availability of food.
3. Poor post-harvest handling: Inadequate harvesting, sorting, grading, packaging and handling practices can cause physical damage, bruising and contamination of food, accelerating spoilage. Small and fragmented farms often lack access to modern post-harvest technologies, leading to significant losses.
4. Inefficient transportation: Inadequate transport infrastructure, long transit times, poor road connectivity and insufficient refrigerated vehicles can expose perishable food to heat, moisture and physical damage. This is particularly significant for fruits, vegetables, dairy, meat and fish, leading to spoilage before they reach markets and consumers.
5. Fragmented Supply Chains & Middlemen: Agricultural produce typically passes through multiple intermediaries (local traders, commission agents, regional mandis, and wholesalers) before reaching retail. Each transfer point delays delivery and increases the risk of spillage and spoilage.
6. Market fluctuations: Sudden changes in demand, prices and supply can make it uneconomical for farmers to harvest and transport perishable produce. During periods of market glut, excess supply of fruits and vegetables may cause prices to fall below the cost of harvesting, leading farmers to leave produce unharvested or allow it to perish.
7. Low Processing Rates: India processes less than 10% of its total agricultural output (compared to 60–80% in developed countries). Without sufficient agro-processing facilities to convert excess harvest into longer-lasting preserved items, surplus fresh produce is left to rot.
8. Excess food in restaurants and events: Large portions, over-preparation due to uncertain demand and elaborate buffets often result in substantial quantities of edible food being discarded. Weddings, festivals and other large gatherings can further increase food waste due to over-ordering, low consumption and inadequate systems for redistributing surplus food.
9. Changing Urban Consumption Habits: Growing urban middle-class populations, increased reliance on food delivery apps, impulse bulk-buying at modern supermarkets, and poor meal planning lead to cooked food spoiling in domestic refrigerators.
10. Lack of awareness and segregation: Limited awareness about proper food storage, portion planning, expiry dates and food redistribution often leads to avoidable food waste. Further, inadequate segregation of food waste from other municipal waste makes recovery, composting and processing difficult, resulting in more food being sent to landfills.

What are the consequences of food loss & waste in India?

1. Threat to food security: Food loss and waste reduce the effective availability of food despite significant agricultural production. Losses during harvesting, storage and transportation, along with waste at the consumer level, reduce the food available for consumption and can undermine efforts to ensure adequate, affordable and nutritious food, particularly for vulnerable populations.
2. Economic losses for farmers: Food loss directly reduces the marketable surplus and income of farmers, as farmers bear the cost of producing, harvesting and transporting food that ultimately gets damaged or spoiled. The NABCONS study (2020–22) estimated post-harvest losses worth ₹26,001 crore in cereals, ₹29,545 crore in fruits and ₹27,459 crore in vegetables in India.
3. Food Inflation: Systemic supply losses reduce the net availability of produce in wholesale mandis. This artificial scarcity drives up retail prices, triggering seasonal spikes in food inflation that disproportionately affect lower- and middle-income consumers.
4. Wasted Freshwater: Agriculture accounts for about 80-90% of India’s freshwater use. Food that is never consumed represents roughly 230-250 cubic kilometers of water wasted annually which is equivalent to the annual water consumption of major urban centers.
5. Greenhouse Gas Emissions & Climate Change: Decomposing organic waste in open municipal landfills releases methane, a potent greenhouse gas that is 28 times more effective at trapping atmospheric heat than carbon dioxide over a 100-year timescale. Food waste accounts for 8-10% of global greenhouse gas emissions.
6. Nutritional losses: Food loss and waste lead to the loss of calories, proteins, vitamins and minerals that could otherwise contribute to improving India’s nutritional security. This is particularly significant because India continues to face substantial malnutrition: NFHS-5 (2019–21) recorded stunting among 35.5%, wasting among 19.3% and underweight among 32.1% of children under five.
7. Increased fiscal and infrastructure burden: Food loss and waste result in significant economic losses while also reducing the efficiency of investments made in agricultural and food infrastructure. The NABCONS study estimated that around 68.9 million tonnes of agricultural produce was lost in 2020-21, with an associated monetary loss of about  ₹92,000 crore to ₹1.5 lakh crore – This represents nearly 1% of India’s GDP and a significant portion of its agricultural gross value added.
8. Impedes sustainable development: Food loss and waste undermine India’s progress towards SDG 2 (Zero Hunger), SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action).

What measures have been taken by the government to reduce food loss and waste in India?

1. Pradhan Mantri Kisan SAMPADA Yojana (PMKSY): It aims to create modern food-processing infrastructure and efficient supply chains from the farm gate to the retail outlet, thereby reducing wastage. Its components include Integrated Cold Chain, food-processing capacities, agro-processing clusters and Operation Greens.
2. PM-FME (PM Formalisation of Micro food processing Enterprises Scheme): Financial and technical support targeted at small-scale and unorganized food processing micro-units to reduce local produce spoilage.
3. Integrated Cold Chain and Value Addition Infrastructure: Supports pre-cooling, sorting, grading, packing, cold storage, refrigerated vehicles and processing facilities to prevent deterioration of perishables during transportation and storage.
4. Operation Greens: Supports the development of integrated value chains for perishable agricultural commodities, including better storage, transportation, processing and market linkages, helping reduce post-harvest losses and distress sales.
5. Mission for Integrated Development of Horticulture (MIDH): Provides financial assistance for establishing and modernising cold-storage facilities for horticultural produce, thereby reducing post-harvest losses.
6. Agriculture Infrastructure Fund (AIF): Promotes investment in post-harvest infrastructure such as warehouses, cold chains, logistics and processing facilities, improving farmers’ ability to store and market produce.
7. Modernisation of foodgrain storage: The government is strengthening FCI and other storage infrastructure. In 2026, the Smart Warehousing System, using AI and IoT-based technologies, was launched to modernise foodgrain warehousing and improve monitoring and management.
8. FSSAI’s “Save Food, Share Food, Share Joy” Initiative: Launched by the Food Safety and Standards Authority of India (FSSAI), this initiative created the Indian Food Sharing Alliance (IFSA). It connects food businesses, caterers, and hotels with registered food recovery agencies and NGOs to safely distribute surplus edible food to needy populations.
9. Food Safety Regulations for Surplus Food (2019): FSSAI enacted formal regulations (Recovery and Distribution of Surplus Food) establishing hygiene standards for donating surplus food, reassuring businesses that safe donations will not face civil liability.

What should be the way forward for efficient food management?

1. Strengthen post-harvest infrastructure: India should expand scientific warehouses, modern silos, cold-storage facilities, pack houses and ripening chambers, particularly near production centres. Decentralised infrastructure can reduce spoilage during storage and transportation, extend the shelf life of perishables and improve farmers’ ability to store produce and avoid distress sales.
2. Develop integrated cold chains: India should develop end-to-end cold-chain networks connecting farm-gate collection centres, pack houses, refrigerated transportation, cold storage, processing units and retail markets.
3. Promote food processing and value addition: Expanding food processing and value addition can reduce post-harvest losses by converting perishable and surplus agricultural produce into products with longer shelf lives.
4. Improve supply-chain efficiency: Strengthening farm-to-market linkages through Farmer Producer Organisations (FPOs), digital agricultural markets, better rural roads and efficient logistics can reduce delays, repeated handling and transit losses. Greater integration of storage, cold chains, processing and retail can ensure faster movement of perishable produce and minimise food loss.
5. Adopt modern technologies: Modern technologies such as IoT sensors, AI, blockchain and data analytics can enable real-time monitoring of temperature, humidity, storage conditions and inventory levels. AI-based demand forecasting can also reduce overproduction and unsold stocks, while digital traceability can help identify bottlenecks and spoilage across the food supply chain.
6. Reduce consumer-level food waste: Consumer-level food waste can be reduced by promoting responsible consumption, better meal and portion planning, proper food storage and awareness about date labels. Households, hotels, restaurants and institutions should adopt demand-based food preparation.
7. Facilitate redistribution of surplus food: Establishing stronger mechanisms to collect, safely store and redistribute edible surplus food from households, restaurants, hotels, retailers and large events to food banks, NGOs and vulnerable communities can prevent avoidable waste. Standardised food-safety protocols and better coordination among FSSAI, local bodies, food businesses and civil-society organisations can make such redistribution more effective.
8. Promote circular food systems: India should adopt a circular approach to food management by ensuring that food and its by-products remain within the resource cycle for as long as possible. Food unsuitable for human consumption can be diverted towards animal feed, composting, biogas and bioenergy, while agricultural residues can be converted into useful products. This can reduce landfill waste, recover resources and promote a more sustainable and resource-efficient food system.

Conclusion: Reducing food loss and waste is not merely a matter of preventing wastage but of improving the efficiency and sustainability of India’s entire food system.
