Challenges of Feeding a Growing Population

The world faces significant challenges in food production, needing to provide approximately six quadrillion additional calories by 2050 to sustain nearly 10 billion people. This demand must be met without expanding agricultural land use, which could lead to detrimental impacts on vital ecosystems like the Amazon and the Congo rainforests. Simultaneously, reductions in emissions from the food sector, which currently accounts for about one-third of total emissions, are necessary, targeting a decrease of around 75-80%. This complex problem requires a careful balance among increasing calorie production, minimizing land utilization, and reducing emissions.
