Environment, Demographics, and Economy in Qing China

Abstract

The Manchu rulers of the Qing dynasty (1644–1912), China’s last, ruled an ethnic diversity of peoples throughout both Inner Asia and China proper. In the process, networks of environmental relationships were formed across Mongolian steppes, Tibetan and Southeast Asian highlands, Manchurian forests, and alluvial plains in the empire’s core, China proper. The dynasty’s main environmental efforts were devoted to the lowland agrarian concentration of water and grain. Yet the empire’s sheer extent also required management of agro-pastoral, pastoral, foraging, and swiddening relations—pursued under conditions of global cooling in the Northern Hemisphere, known as the Little Ice Age. Mineral inputs from foreign and domestic sources, as well as New World crops, were critical not only for the dynasty’s material development, but also entailed debilitating costs—most particularly deforestation and soil erosion. As it adapted to dynamic demographic and ecological conditions, the dynasty developed many structures for the maintenance and resiliency of its environmental relations, which included existential interactions with select animals and plants, to produce the world’s largest population of its time. The Qing achievement can be evaluated differently according to timescales and wide-ranging criteria that transcend crude Malthusian parameters. However, its political and demographic accomplishments must be qualified from an environmental perspective in light of the mid-19th-century breakdown of many of its environmental networks that directly contributed to its demise and that of the 2,000-year-old imperial system.
