Sumary of Informing policy for long-term global food security:
- More than 820 million people in the world don’t have enough to eat, while climate change and increasing competition for land and water are further raising concerns about the future balance between food demand and supply.
- The results of a new IIASA-led study can be used to benchmark global food security projections and inform policy analysis and public debate on the future of food.
- Despite the fact that food supply has increased dramatically since the 1960s, the question of how to eradicate global hunger — one of the Sustainable Development Goals — and feed the growing world population in years to come, remains a major challenge.
- Climate change and increasing competition for land and water are further exacerbating the problem, making the need for effective policies to ensure global food security and a better understanding of the main driving forces of global hunger ever more urgent.
- Scientists typically use quantified global scenarios and projections to assess long-term future global food security under a range of socioeconomic and climate change scenarios.
- However, due to differences in model design and scenario assumptions, there is uncertainty about the range of food security projections and outcomes.
- The study’s findings provide strong support for the view that food demand will increase by between 35% and 56% over the period 2010-2050, mainly due to population growth, economic development, urbanization, and other drivers.
