The role of technology in reducing food waste and improving food security.


Food waste and insecurity are major challenges facing the world today. According to the United Nations, around 931 million people suffered from hunger in 2020, while nearly one-third of all food produced goes to waste. Food waste contributes to greenhouse gas emissions, consumes valuable resources, and wastes money. Fortunately, technology has played a significant role in addressing these issues, from reducing food waste to improving food security. In this article, we will explore the role of technology in reducing food waste and improving food security.

The Problem of Food Waste

Food waste is a global problem that affects both developing and developed countries. The Food and Agriculture Organization of the United Nations estimates that 1.3 billion tons of food, which is approximately one-third of all food produced globally, goes to waste every year. The impact of food waste on the environment and the economy is significant. Food waste contributes to greenhouse gas emissions, wastes land, water, and other valuable resources, and costs the global economy around $1 trillion annually.

The Causes of Food Waste

Food waste can occur at different stages of the food supply chain, from production to consumption. The main causes of food waste include:

Overproduction and Harvesting

Farmers often overproduce food to ensure that they have enough to sell. However, this can lead to food waste if there is no demand for the excess produce. Additionally, food can be wasted during harvesting, processing, and distribution.


Food can spoil due to improper storage, transportation, or handling. This can lead to food waste and a loss of revenue for farmers and food manufacturers.

Retail and Consumer Waste

Consumers and retailers often waste food by throwing away products that are still edible but have passed their sell-by date or have minor cosmetic imperfections.

The Impact of Food Waste

Food waste has significant environmental, economic, and social impacts. It contributes to greenhouse gas emissions, as decomposing food releases methane, a potent greenhouse gas. Additionally, food waste wastes valuable resources, such as water and energy, and contributes to the loss of biodiversity.

The Role of Technology in Reducing Food Waste and Improving Food Security

Technology has played a critical role in reducing food waste and improving food security. Here are some ways in which technology has made a positive impact:

Food Traceability and Management Systems

Technology has enabled the development of food traceability and management systems, which help to track food products throughout the supply chain. These systems can help identify inefficiencies and areas where food waste can be reduced. Additionally, they can help ensure that food products are safe and meet quality standards.

Food Preservation Technologies

New technologies are being developed that help to extend the shelf life of food products. For example, modified atmosphere packaging (MAP) and vacuum packaging can help to preserve food by reducing oxygen levels, which slows down the growth of bacteria and other microorganisms. Additionally, new refrigeration technologies, such as solar-powered refrigerators, can help to reduce food waste in areas where electricity is scarce.

Predictive Analytics

Predictive analytics can be used to forecast demand for food products. By analyzing data on consumer behavior and market trends, retailers and food manufacturers can better anticipate demand and adjust production accordingly, reducing the risk of overproduction and waste.

Food Recovery and Redistribution

Food recovery and redistribution programs use technology to connect businesses with surplus food to charities and organizations that can distribute it to people in need. Apps such as Too Good To Go and Olio allow consumers and businesses to share surplus food and reduce waste.

Several apps have been developed to help reduce food waste at the consumer level. For example, the app “FoodKeeper” helps users to identify the shelf life of different food products and provides recommendations for how to store them properly. Other apps, such as “NoWaste” and “Too Good To Go,” allow users to purchase surplus food from restaurants and grocery stores at a discounted price.

The Role of Technology in Improving Food Security

Food security is defined as having access to sufficient, safe, and nutritious food to meet dietary needs and preferences for an active and healthy life. Technology has played a critical role in improving food security in the following ways:

Precision Agriculture

Precision agriculture uses technology such as GPS, sensors, and drones to optimize crop production. By collecting data on soil conditions, weather patterns, and plant health, farmers can make informed decisions about when to plant, fertilize, and harvest their crops. This can increase crop yields, reduce waste, and improve the efficiency of farming practices.

Climate-Smart Agriculture

Climate-smart agriculture uses sustainable farming practices that help to mitigate and adapt to climate change. For example, conservation agriculture involves minimizing soil disturbance, maintaining soil cover, and rotating crops to improve soil health and reduce greenhouse gas emissions. Additionally, agroforestry involves growing trees alongside crops, which can help to sequester carbon and improve soil fertility.

Mobile Technology

Mobile technology has enabled farmers to access information and resources that can improve their productivity and profitability. For example, farmers can use mobile apps to access weather forecasts, market prices, and agricultural advice. Additionally, mobile money services can enable farmers to receive payments and access financial services without having to travel to a physical bank.

Food Fortification

Food fortification involves adding essential vitamins and minerals to staple foods such as flour, rice, and salt. This can help to address micronutrient deficiencies and improve the health of vulnerable populations. Technology has enabled the development of cost-effective and scalable food fortification programs, such as the use of micronutrient powders that can be added to home-cooked meals.
