India is one of the world's major food-producing countries, yet a considerable amount of food is lost or wasted before it can be consumed. These losses can occur at almost every stage of the food supply chain—from harvesting and storage to transportation, processing, retail and households.
Reducing food loss and waste can help India improve food security, protect natural resources, support farmers and create more efficient food systems. FAO and UNEP describe reducing food loss and waste as a “triple win” for food security, the environment and sustainable food systems.
Food Loss vs Food Waste
Food loss and food waste are related but occur at different stages.
Food loss generally happens between harvesting and the retail stage. Poor storage facilities, inadequate transportation, moisture, temperature changes, pests and delays in processing can all contribute to losses.
Food waste generally occurs closer to the consumer, including at retail stores, restaurants, food-service businesses and households. Uneaten meals, excess preparation and food discarded because of appearance or date-label concerns are common examples.
Understanding where food is being lost is important because different problems require different solutions.
Why Food Loss Is a Major Issue for India
Food waste is not simply the loss of a product. Producing food requires water, agricultural land, energy, labour, fertilizers, packaging and transportation.
When food is lost, the resources used to produce that food are also effectively wasted.
A recent ICRIER report notes that India's food losses were estimated at around ₹1.53 lakh crore annually, based on the large-scale NABCONS study covering 2020–2022.
Reducing these losses could therefore provide economic benefits while making better use of India's agricultural resources.

Improving Storage and Transportation
One of the most important ways to reduce food loss is to improve infrastructure between farms and markets.
Perishable products such as fruits, vegetables, dairy products, meat and seafood can deteriorate quickly when exposed to unsuitable temperatures or excessive delays.
Better cold-chain infrastructure, warehouses, transportation systems and packaging can help maintain food quality for longer.
For some agricultural products, improved drying and moisture control can also reduce deterioration during storage.
Technology can further help businesses monitor temperature, humidity and inventory, allowing problems to be identified before products become unusable.
The Role of Food Preservation
Food preservation can play an important role in extending the useful life of food when appropriate methods are selected for the product.
Traditional and modern preservation methods include:
- Drying and dehydration
- Refrigeration and freezing
- Fermentation
- Canning
- Pickling
- Pasteurisation
- Controlled acidity
- Use of permitted food preservatives
Ingredients such as citric acid, malic acid, lactic acid and other permitted food additives can serve specific technological functions in suitable food products. Their use should always comply with applicable food-safety regulations and prescribed limits.
Effective preservation is not about keeping food indefinitely. It is about safely maintaining quality, stability and shelf life while reducing unnecessary spoilage.
Food Processing Can Reduce Seasonal Losses
India produces large quantities of fruits, vegetables and other agricultural products that can be highly seasonal.
When supply exceeds immediate demand, some produce may deteriorate before reaching consumers. Food processing can provide another route for suitable surplus produce.
Depending on the product, agricultural produce can be processed into:
- Purees and sauces
- Pickles
- Dried fruits and vegetables
- Powders
- Frozen foods
- Beverages
- Ready-to-use ingredients
Processing can increase shelf life and create additional value for agricultural products.
At the same time, food manufacturers should also focus on reducing waste generated during processing through better production planning, inventory management and responsible management of unavoidable organic residues.
Turning Food Waste into Useful Resources
Not all food waste can be prevented. However, unavoidable organic waste does not necessarily have to end up in a landfill.
Properly segregated food waste can potentially be used to produce compost, biogas and other useful resources.
FAO and UNEP have highlighted circular approaches in which unavoidable food waste can be converted into compost or used for biogas production.
This creates a more circular system:
Food production → Consumption → Organic waste → Resource recovery → New value
Such approaches can reduce the amount of organic waste sent to landfills while recovering useful resources.
What Can Food Businesses Do?
Restaurants, cafés, hotels, supermarkets and food manufacturers can take several practical steps.
Businesses can begin by measuring how much food is being discarded and identifying where the largest losses occur.
Other measures include:
- Better inventory management
- Improved demand forecasting
- Appropriate portion sizes
- Better storage practices
- First-in, first-out inventory systems
- Using suitable surplus ingredients
- Improving packaging
- Separating organic waste
- Composting or sending suitable waste for resource recovery
Measurement is particularly important. WRI India has highlighted the need for coordinated action and better data while working with businesses and other stakeholders to reduce food loss and waste across India's food system.
Consumers Also Have a Role
Households are an important part of the food system.
Simple changes can help reduce unnecessary waste:
Plan before shopping: Buying only what is needed can prevent excess food from expiring.
Store food correctly: Appropriate refrigeration and storage can extend shelf life.
Use leftovers: Properly stored leftovers can become another meal instead of becoming waste.
Understand date labels: Consumers should distinguish between different types of date information rather than automatically discarding food.
Serve appropriate portions: Preparing or serving more food than necessary can lead to avoidable waste.
Small changes across millions of households can have a significant cumulative effect.
Building a More Circular Food System
India's food-loss challenge also creates opportunities for innovation.
Businesses are already exploring solutions including solar-powered cold chains, smart storage, food upcycling and waste-to-value models. WRI India's recent compendium highlights examples of Indian enterprises working on these areas.
The next step is to make such solutions more accessible and scalable.
Farmers, food processors, logistics companies, retailers, restaurants, municipalities, financial institutions and consumers all have a role to play.
Conclusion
Reducing food loss and waste is not only about throwing away less food. It is about building a more efficient, sustainable and resilient food system.
Better storage can protect agricultural produce. Improved transportation can reduce deterioration. Food preservation and processing can extend shelf life. Responsible consumption can reduce household waste, while composting and biogas can help recover value from unavoidable organic waste.
For India, every reduction in food loss represents an opportunity to make better use of the food, water, land, energy and labour already invested in producing it.
The goal should therefore be simple: produce efficiently, preserve responsibly, consume wisely and recover value from what remains.
