China's Total Population by Sex and Age, Census 1990
• Pre-1958: China’s economy is based on agricultural production
• Great Leap Forward– Goal: Surpass Britain’s industrial
output by 1972– Method: Focus on steel
production and coal and energy output
• Industrial yields increased…
• China’s agricultural production decreased…
• Massive demographic shock…

“The increase in per capita energy use prior to the last two decades of the 20th century is related to the evolving nature of societies as they move from primitive, to agricultural, to industrial, and then to technological.”James Galloway (1998: 18)

• China is one of the world’s major centers of biodiversity *– Forests have a rich array of species – China possesses ~2,800 tree species *
• China’s forests and biodiversity have long been under threat due to logging and hunting, as well as the “conversion of habitats to form fields and human settlements.” *
• At least eight large mammal species are thought to have been exterminated since imperial times*

• High rate of deforestation (~1.2% per year)**
• Problems with Protected Areas:– Remoteness and poverty of regions– Poorly paid and trained staff– Gaps in protected area system
• Poor regeneration– “estimated that due to inappropriate
logging practices, one-third of all forests cut before 1979 were replaced by degraded mountain slopes” *
– Replanting “green deserts”• Lack of biological diversity *

• In China, we have seen that…– Population keeps growing– Urbanization keeps growing– Carbon emissions keep increasing– China is committed to addressing failures,
such as its commitment to replanting forests.
• Threats to Biodiversity– Population Growth…– Affluence…
• China has experienced rapid growth in its economic sector in conjunction with rapid growth in energy consumption
• During the economic slowdown in the late 1990s… China saw energy and CO2 emissions decline.
– Counteract Affluence…• Garbaccio et al.
– Possible to control carbon emissions through taxation.
