Land provided almost what percent of our requirements
Answers
Answer:
today the world uses approx 50% of land for agriculture
Explanation:
Today, the world population uses approximately 50 percent of total habitable land for agriculture.
How much of our habitable land would we need if the global population were to adopt the average diet of any given country? The results are presented in the map shown here. We have color-coded the map based on our current agricultural land requirements and our physical land constraints as follows:
Countries shown in blue have an average diet which, if adopted globally, would result in less land use for agriculture than current levels (i.e. their HALF index is less than 50 percent).
Countries shown in yellow have an average diet which, if adopted globally, would require an expansion of agricultural land from our current allocation, but would be physically viable within global land constraints (i.e. their HALF index is between 50 and 100 percent).
Those shown in orange have dietary requirements which would not be feasible at a global scale, even if we converted all habitable land to agriculture (i.e. their HALF index is greater than 100 percent).
You can explore the exact percentage values by hovering over any country in the interactive map.
Overall, there is a 14-fold difference in land requirements across national diets. If we were to achieve equitable diets using less land than we currently do, we can see that the world would have to converge towards the dietary compositions of countries across South Asia, Sub-Saharan Africa, and some Latin American countries (i.e. the countries shown in green). The largest sub-set of countries fall within the middle bracket: global adoption of such diets would require agricultural expansion, but may be physically viable within habitable land resources. However, there are also a number of countries which fall into the orange category: it would be ecologically impossible for everyone to eat the diet in North America, Brazil, Argentina, Australia, New Zealand, and several countries across Europe.
