Food Security

  • With the world's population expected to hit 9.7 billion by 2050, agriculture needs to become more productive and sustainable.
  • Technology can help transform the global food production system and mitigate its impact on the climate and environment.
  • Digital agriculture systems can also be used to reduce food waste and at every stage of the supply chain.

When agriculture first took root around 12,000 years ago, it triggered a change in how people lived. Dubbed the “Neolithic Revolution", the promise of a reliable food supply enabled humans to give up their nomadic hunter-gatherer lifestyles. Out of these first settlements grew cities and complex civilizations, shaping the world as we know it.

Agriculture has allowed the human population to grow explosively, and its industrialization over the past two centuries fueled the jump from 1 billion to nearly 7.7 billion people. As a result, agriculture in its modern form has tested the limits of our environmental resources.

Have you read?

Agriculture causes about 23% of human-caused greenhouse gas emissions and uses up to 92% of the world’s freshwater. According to a report by the WWF and British food retailer Tesco, around 40% of food grown goes uneaten. China loses roughly 35 million tons of grain before retail each year, or about 5% of the 685 million tons of grain produced in 2021.

With a projected 2 billion more mouths to feed across the world by 2050, agriculture needs to simultaneously become both more productive and sustainable. That requires increased investment and adoption of productivity-boosting technology and participation from young people and smallholder farmers.

Technology can transform agriculture

Human ingenuity, scientific breakthroughs and technological advances have given the world an unprecedented array of tools to transform the food system and mitigate its impact on nature and climate.

In precision agriculture, real-time weather forecasting helps farmers with day-to-day decisions on when and how much to irrigate, fertilize and apply pesticides to their crops.

Controlled-environment agriculture promises to further reduce the impact. Some smart greenhouses are completely automated, run by algorithms that ensure optimal conditions for plant growth by adjusting inputs like roof ventilation, artificial lighting and heating.

Ultra-high resolution imaging can spot early symptoms of disease, water stress and soil degradation, while drones spray fertilizer, pesticides, and water with pinpoint accuracy. By reducing the guesswork in farming, smart agriculture enables crops to reach their full genetic potential without the excessive use of chemical inputs.

Biotechnology is another field that continues to make breakthroughs. Advances in seed science are making crops more resistant to drought, pests and infestation, boosting agricultural productivity and increasing the resilience of food producers to environmental shocks.

World must also tackle issue of food waste

But increasing the ability to produce more food using fewer resources will have a limited impact, if the world does not also tackle the problem of food waste and loss.

Food is lost and wasted at each stage of the food supply chain, from harvest to storage to transportation, and then at the retailer and consumer end. Here, again, technology can play an important role.

Increasing the digitalization of agriculture improves the overall efficiency of the entire agri-food system. Online marketplaces connect farmers directly with consumers, reducing the number of intermediaries and transit nodes that food must pass through. This not only boosts the income of farmers by cutting out the middlemen, but it also leads to less time spent in transit, reducing the amount of loss and waste.

Reducing this waste requires a re-engineering of the logistics system that moves food from farm to fork. For example, Pinduoduo is developing a new agri-focused logistics infosystem that plans out new cold-chain transportation routes to eliminate unnecessary transits.

Garlic sold by farmers in Henan to consumers in Shanghai on our platform travelled 16.1% less distance and expended 38.1% less fuel per ton. It also helped to cut food loss and waste to 25% of production, instead of the global average of around 40%.

China is also taking steps to curb food waste at the national level. Last year, Chinese lawmakers voted to adopt an anti-food-waste law in April. According to the law, catering service providers can impose a levy on customers who leave excessive amounts of food waste.

Farmers need to adopt agricultural technology

The success of any agricultural technology ultimately rests on the rate of adoption among farmers, in particular, smallholder growers.

Five of every six farms in the world are smaller than two hectares (the size of about three soccer fields) and collectively they produce a third of the world’s food. In the case of China, smallholder farmers account for as high as 80% of food production.

Many of these smallholder farmers are older and received less formal education, making it more difficult for them to adopt technology without support. The availability and accessibility of internet infrastructure is also a potential barrier in some countries.

Another critical ingredient is young talent. Encouraging more young people to take up agriculture – whether it is young scientists diving into agricultural research or Gen Z entrepreneurs selling fruit online – leads to more innovation, more ideas and more vitality.

An annual Smart Agriculture Competition, organized by Pinduoduo, with support from the UN Food and Agriculture Organization, attracts participating teams from top universities and research institutes from around the world to devise technology solutions that can help smallholder farmers increase their productivity and environmental sustainability.

In this year’s contest, 80% of the participants are in their 20s, which bodes well for the future of agriculture. Technology developed during the competition is now applied in several major agricultural regions in China.

Agriculture needs digital transformation

As a primary sector that employs millions of people directly and throughout the supply chain, agriculture has lagged behind many other sectors in digitalization and application of digital technology. Luckily, however, it is not too late to catch up, but the sector needs more investment, more new ideas and greater participation.
