Perhaps one of the most overlooked opportunities for improving global food security is reducing food loss and waste. The world does not necessarily have to produce every additional tonne of food that it will need in the future if it can prevent substantial quantities of existing food from being lost. FAO estimates that approximately 13.2 percent of food is lost globally between the farm and retail stages, while another 19 percent is wasted at retail, food-service and household levels, according to 2024 UNEP statistics. Food loss and waste are therefore not merely economic inefficiencies. They represent wasted land, water, energy, labour and financial investment. They also contribute to climate change. FAO estimates that food loss and waste account for approximately 8–10 percent of global greenhouse-gas emissions. The developing world often faces particularly serious post-harvest losses because of inadequate cold chains, storage facilities, transport infrastructure, packaging and processing capacity. For fruits and vegetables, the absence of reliable cold-storage infrastructure can mean that farmers lose part of their production before it reaches consumers. Investment in warehousing, refrigerated transport, food processing, packaging, logistics and digital supply-chain management can therefore have food-security benefits comparable to increasing farm productivity. In other words, the future of agriculture is not only about producing more. It is also about losing less.
Another major transformation must occur in the way societies define food security. For decades, food policy frequently focused on calories, cereal production and national availability. These remain important, but they are no longer sufficient. A population can consume enough calories while simultaneously suffering from micronutrient deficiencies, obesity, diabetes and cardiovascular disease. FAO’s State of Food and Agriculture 2024 estimates that the quantified hidden costs of agrifood systems amounted to approximately $11.6 trillion in purchasing-power-parity terms in 2020 across 156 countries. The majority of these hidden costs were associated with health impacts, particularly unhealthy dietary patterns and non-communicable diseases. FAO has estimated that health-related hidden costs account for approximately 70 percent of total quantified hidden costs, equivalent to around $8.1 trillion annually in its assessment. This has profound implications. The food system should not be judged simply by whether it produces cheap calories. It should be evaluated according to whether it provides affordable, nutritious and sustainable diets. That means agricultural policy, public health policy and food policy can no longer operate in isolation. Governments must increasingly encourage the production and availability of fruits, vegetables, whole grains, pulses and other nutritious foods while addressing excessive consumption of highly processed products, sodium, unhealthy fats and excessive quantities of certain animal products. The objective should be a food system that supports both healthy people and a healthy planet.
No country can realistically produce every food product efficiently. Some countries possess abundant water and land. Others have advanced technology and capital. Some have favourable climates for particular crops, while others possess large consumer markets but limited agricultural resources. International agricultural trade allows these comparative advantages to complement one another. The OECD-FAO Agricultural Outlook estimates that by 2034 approximately 22 percent of calories consumed globally will cross international borders, compared with about 17 percent two decades ago. This means global food security increasingly depends on functioning international markets. However, recent global shocks have demonstrated the vulnerability of highly concentrated supply chains. Wars, pandemics, export restrictions, extreme weather, energy-price shocks and geopolitical tensions can rapidly affect fertiliser, grain, edible-oil and food prices. A resilient food system therefore requires both international trade and strategic resilience. Countries should diversify import sources, maintain appropriate strategic reserves, strengthen domestic production of critical foods, improve logistics and avoid unnecessary trade restrictions. At the same time, excessive protectionism can make food more expensive and reduce global efficiency. The objective should not be complete self-sufficiency. It should be strategic food resilience.
Modern agriculture depends heavily on fertilisers, pesticides, improved seeds, energy and machinery. Fertilisers have played a critical role in increasing yields, particularly in regions where nutrient depletion limits agricultural productivity. But excessive or inefficient fertiliser use can contribute to environmental damage, water pollution and greenhouse-gas emissions. The future will therefore require a transition from input-intensive agriculture to knowledge-intensive agriculture. Instead of applying the same quantity of fertiliser across an entire field, farmers should increasingly apply nutrients according to soil conditions and crop requirements. Precision agriculture can make this possible. Digital soil mapping, remote sensing, variable-rate application and improved nutrient management can potentially increase yields while reducing unnecessary input use. The principle is simple: the future farmer should apply more knowledge and fewer wasted resources. Technology alone will not transform global agriculture. Transformation requires investment. Farmers need capital to purchase improved seeds, irrigation equipment, machinery, storage systems and digital technologies. Governments need resources for research, extension services, infrastructure and water management. Private investors need incentives to develop agricultural processing, logistics, cold chains and technology. Climate finance must also become more accessible to agriculture. Developing countries often face the greatest climate-related agricultural risks while possessing the least financial capacity to adapt. Investment should therefore move beyond emergency relief toward resilience-building infrastructure. A dollar invested in climate-resilient irrigation, flood protection, drought-resistant seeds, storage and early-warning systems can potentially reduce future losses and protect livelihoods. Agricultural finance must also become more inclusive. Small farmers frequently face difficulties obtaining formal credit because they lack collateral, reliable records or access to banking services. Digital financial services, crop insurance, warehouse-receipt systems and innovative lending mechanisms can help address these constraints.
The world is entering one of the most consequential periods in the history of food and agriculture. Nearly 10 billion people will eventually need to be fed. Hundreds of millions remain hungry today. Billions cannot consistently afford healthy diets. At the same time, agriculture is confronting unprecedented pressure from climate change, water scarcity, land degradation and resource depletion. Yet the future is not necessarily bleak. Agriculture possesses enormous potential for innovation. Artificial intelligence can improve decisions. Precision irrigation can save water. Biotechnology can improve crop resilience. Regenerative practices can restore soils. Better logistics can reduce food losses. Digital marketplaces can connect farmers with consumers. Improved livestock systems can reduce emissions. International trade can move food from surplus regions to deficit regions. But technology alone will not be enough. The decisive factor will be whether societies can build institutions, policies and investment systems capable of making these innovations accessible to the millions of farmers who produce the world’s food. The future of food will therefore depend not only on what happens inside laboratories or on large commercial farms. It will also depend on what happens in the fields of small farmers in South Asia and Africa, in the irrigation systems of water-stressed regions, in agricultural universities, in rural financial institutions, in food-processing plants and in international markets. The global agricultural system must move from an era of maximum extraction to sustainable productivity; from production alone to nutrition; from fragmented supply chains to resilient food systems; and from traditional farming to knowledge-driven agriculture. The world has successfully increased food production for generations. The next challenge is more demanding: to feed everyone, nourish everyone and protect the resources required to feed future generations. That is the real meaning of feeding the future. It is not simply about producing more food. It is about building a food system capable of sustaining people, prosperity and the planet simultaneously and for generations to come.
