According to the World Population Prospects: 2017 Revision, released by the United Nations on June 21, 2017, the world's population, currently 7.6 billion, is projected to reach 8.6 billion by 2030, 9.8 billion by 2050, and 11.2 billion by 2100, with population growth concentrated in the poorest countries, posing challenges to achieving the Sustainable Development Goals. Socio-economic changes associated with population growth and demographics are expected to increase demand for food and the environmental burden of agriculture in developing countries.
