Figure 1 tracks the per-person resource demand Ecological Footprint and biocapacity in China since 1961. Biocapacity varies each year with ecosystem management, agricultural practices (such as fertilizer use and irrigation), ecosystem degradation, and weather, and population size. Footprint varies with consumption and production efficiency. Where a dotted line is shown, interpolation estimates have been used in place of highly unlikely outliers in the results.
