What will happen to agriculture in 2050?

By 2050 agriculture will remain an important determinant of economic growth, poverty reduction, and food security, despite the proportional decline of agricultural revenues in national gross income. Water use in agriculture will remain substantial, irrigated areas will expand and competition for water will increase in all sectors. Despite overall supplies of land and water will most likely be enough to achieve global food production goals in 2050, poverty and food insecurity will remain pressing challenges in several regions. While water will be sufficient to satisfy global food demand, an increasing number of regions will have to cope with growing water scarcity due to increasing competition. The outlook for 2050 provided by this paper reveals the demand for innovative and effective governance mechanisms to mitigate the impacts of growing water shortages. Investments in water technologies and infrastructure will be required for efficient water use, protecting food security and natural resources. Read more…
