Temporal and spatial assessment of natural resource use in China using ecological footprint method

Abstract

China has about 20% of the world's population. With rapid economic development and substantial population increase, China is now faced with severe conflicts between limited natural resources and increasing resource requirements. In this study, we used the ecological footprint method to assess the resource demand and supply conditions of each land use in China between 1978 and 2003. In order to provide insight into the spatial heterogeneity of resource demand and supply conditions, we also assessed the ecological footprint at provincial level in 2002. An ecological footprint curve method was introduced to compare differences in natural resource use, economic development and technological progress among different countries and provinces. The results showed that the ecological footprint, biocapacity and ecological deficit per capita for China have all been increasing during 1978–2003. The ecological footprints per person in northern and eastern China were larger than those in southern and western China. The ecological deficits per person in southern and eastern China were more severe than those in northern and western China. Though the resource use efficiency has increased considerably during 1978–2003, it was still much lower than those of the Netherlands, France, South Korea, Mexico, the Philippines and India.
