Culture and the Environment
The Culture and the Environment domain tests how societies use, modify, and are limited by natural systems: environmental perspectives, population-resource debates, agriculture and land degradation, and sustainability.
Perspectives
Environmental determinism held that climate and terrain shaped culture; modern geography rejects it as oversimple. Possibilism, associated with Vidal de la Blache, argues that environment offers possibilities, and technology and culture select among them. Cultural ecology studies the interaction; political ecology adds power and economics.
Population and resources
Malthus predicted population growth would outrun food supply; Boserup argued that population pressure induces agricultural intensification. Carrying capacity is the population an area can support given technology and consumption, not a fixed number. The tragedy of the commons describes overuse of unowned resources; Ostrom showed communities can govern commons. Ecological footprint converts consumption into land area.
Agriculture and land use
Subsistence agriculture feeds the farmer; commercial agriculture sells output. Shifting cultivation rotates fields in tropical forests; wet-rice paddies support dense populations; pastoral nomadism follows seasonal pasture. The Green Revolution raised yields through improved varieties, irrigation, and fertilizer but increased inequality and water use. Irrigation can waterlog and salinize soils; overgrazing and deforestation can accelerate erosion and desertification.
Sustainability
The Brundtland Report of 1987 defined sustainable development as meeting present needs without compromising future generations. Environmental impacts vary with population, affluence, and technology, often summarized as IPAT.
Worked example
In the Sahel, drought reduces vegetation; farmers keep more goats; grazing removes remaining cover; albedo rises and soil erodes; the next drought is worse. This positive feedback shows how human response can amplify environmental change, an example for cultural ecology rather than simple determinism.
Traps
- Confusing determinism, where environment causes culture, with possibilism.
- Mixing up Malthus, who stressed food limits, with Boserup, who stressed intensification.
- Treating carrying capacity as fixed rather than technology-dependent.
- Assuming all irrigation is benign; salinization and waterlogging are common.
