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 fertiliser, 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.
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 digitalisation 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 reengineering 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 per cent less distance and expended 38.1 per cent less fuel per tonne. It also helped to cut food loss and waste to 25 per cent of production, instead of the global average of around 40 per cent.
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 per cent 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, organised by Pinduoduo, with support from the United Nations 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 per cent 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.
With the task of feeding a growing global population, agriculture stands at yet another important juncture. It is in our collective interest to help agriculture and the global food production system transform so that they can nourish us in a sustainable manner.
