 Food markets lie at the heart of the development process and they evolve together with our society. Since the end of the last century, world food trade has doubled in real value and developing countries now account for one third of the world total. The 2020 edition of the State of Agricultural Commodity Markets discusses how agricultural trade and well functioning markets can contribute to sustainable development. Today, more foods are traded, more people buy food in supermarkets. Quality standards are becoming increasingly important and e-commerce facilitates exchange. A food product can change borders many times. A country produces and exports agricultural commodities. Another country processes them into food for further export. The report estimates that about one third of world food trade is taking place within such global value chains and crosses borders at least twice. Lower trade barriers promote global value chains and participation in global value chains increases agricultural productivity and farm incomes. But not all farmers have the resources and the skills to compete globally. Inclusive business models can help farmers joining modern value chains that can promote economic growth and ensure food security.
