China's Tire Demand Rolls over Southeast Asian Forests

Geographer Jefferson Fox thought he was on to something big when the Chinese military stripped his team’s weather monitoring equipment from a montane rubber plantation in the run-up to last year’s Olympics. How big? In the past 20 years, more than 1.2 million acres (485,000 hectares) of evergreen broadleaf and secondary forests have been cleared throughout Southeast Asia to make way for rubber plantations to fuel China’s growing appetite for automobile tires.

Fox—who is based at the East West Center in Honolulu—warns in Science this week that the environmental consequences of these massive land use changes, particularly on water resources, could be devastating.
Economists are also sounding the alarm, cautioning in a series of articles set to be published in Human Ecology that government policies that have forced these farmers to abandon traditional agriculture practices will leave them vulnerable to future fluctuations in rubber prices.

Swidden, or slash-and-burn, agriculture was once practiced throughout the world as a means to cultivate on otherwise infertile soils. But with the rise of modern agricultural techniques, Europeans began to view it as an abominable and primitive practice. As Capt. P. Cupet, a member of France’s Pavie Mission to Indochina in the late 19th century once wrote, “These savages are the greatest destroyers of forests I know.”

But Fox and his two coauthors believe these “savages” were better at preserving biodiversity than current land-use practices encouraging monoculture, or single-crop, agricultural development in Southeast Asia. Today, Laos, Cambodia, and Thailand—with international encouragement—have adopted laws that criminalize swidden agriculture, or otherwise restrict land-use options to make the practice impossible. As a result, Fox says that Chinese investors have been able to move in and secure sometimes questionable deals that allow them to develop rubber plantations on lands once populated by leopards, monkeys and tigers.
