Abstract In a world increasingly affected by global environmental changes, Low Income countries will play an ever more central role in determining the future health of the biosphere. While global use of the biosphere's capacity has increased over the past 45 years, per capita demand for biocapacity, as measured by the Ecological Footprint, has only increased in high-income countries and has remained constant or fallen in middle- and low-income nations. Consumption has increased faster than population in high-income nations, while population growth has been the dominant factor in middle- and low- income countries. Although listed in the middle-income group of countries, China showed atypical trends in the past 45 years, with a rapid increase in per capita Ecological Footprint that outstrip its gains in income. Typical trends were instead noticed for India, whose per person Ecological Footprint has fallen slightly. The results of this paper show that decisions made in China and India will be of fundamental importance for future global sustainability.
