MA Scenarios Percent Change by 2050 Food Demand Water Withdrawal
{"Image DocumentName": "MA Scenarios Percent Change by 2050 Food Demand Water Withdrawal", "Image ImageDescription": "100. Food Demand. Water Withdrawal % 70-85% 50. MA Synthesis data on p. 17: Under all four MA scenarios, the projected changes in drivers result in significant growth in consumption of ecosystem services, continued loss of biodiversity, and further degradation of some ecosystem services. [5] \u25a0 During the next 50 years, demand for food crops is projected to grow by 70\u201385% under the MA scenarios, and demand for water by between 30% and 85%. Water withdrawals in developing countries are projected to increase significantly under the scenarios, although these are projected to decline in industrial countries (medium certainty). \u25a0 Food security is not achieved under the MA scenarios by 2050, and child malnutrition is not eradicated (and is projected to increase in some regions in some MA scenarios) despite increasing food supply and more diversified diets (medium certainty). \u25a0 A deterioration of the services provided by freshwater resources (such as aquatic habitat, fish production, and water supply for households, industry, and agriculture) is found in the scenarios, particularly in those that are reactive to environmental problems (medium certainty). \u25a0 Habitat loss and other ecosystem changes are projected to lead to a decline in local diversity of native species in all four MA scenarios by 2050 (high certainty). Globally, the equilibrium number of plant species is projected to be reduced by roughly 10\u201315% as the result of habitat loss alone over the period of 1970 to 2050 in the MA scenarios (low certainty), and other factors such as overharvesting, invasive species, pollution, and. climate change will further increase the rate of extinction.
