WORLD AND IRAN IN 2050; THE STATUS OF SOCIOECONOMIC FACTORS RELATED TO SUSTAINABLE DIET

Unsustainable development has increased pressure on the natural environment in recent years. During the last few decades, the unprecedented increase comes with high environmental costs. A sustainable diet is a concept advocated by the Food and Agriculture Organization (FAO) to reduce the environmental costs of human diets. The main aim of this study is to review the status of socioeconomic factors related to the sustainable diet in the world and Iran in 2050. So, we reviewed all related studies that predicted and simulated the status of the world and Iran in these years in the association with socioeconomic factors.By the year 2050, the world population will reach about nine billion people. The total of this increase will occur in developing countries and approximately 70% of the population will be urban (the current urban population is 49%). United Nations predicts 2050 population of Iran to reach 110 million in the high variant scenario, which more than 85% of them will live in the urban area (1950: 27.5%, 2016: 74%). As the world s population becomes increasingly urbanized the proportion of persons living in poverty in cities increases. Globally, agriculture has met the demands of this rapidly growing urban population, including food that is more energy-intensive, land-based, water-based and greenhouse-gas-intensive. An amazing change is predicted to occur in today s developing countries driven by income growth. This income growth, especially in developing countries, which allows populations not only satisfy their daily calorie needs but also diversify their diet to include more proteins. It is estimated that in 2050 food production should increase by 50% globally and 70% in developing countries to ensure food for its population. Crop demand is expected to increase by 84 percent from 2000 to 2050. It is estimated that if food was to increase by 70% by 2050, the availability of water should increase by 55% and energy by 50%. Over the next 100 years, due to growing emissions, could warm the earth by 5 ° C relative to the pre-industrial period.In 2050, when the world is warmer, with lower capacity for food production, higher urbanization and population and people tend to consume more calories and meat, reaching a sustainable diet future is harder than now. To enhance sustainable food security, strengthen international trade arrangements to compensate for different impacts of climate change and reduce greenhouse gas emissions are essential to overcome these obstacles to having a sustainable diet.
