Interdependence of Environmental, Social, Cultural, and Economic Systems
What this domain tests
You need to explain how environmental, social, cultural, and economic systems interact through mechanisms, not just say everything is connected. Level 2 answers show feedback, trade-offs, and consequences across scales.
Core rules
A system is a set of parts, relationships, and a purpose; its boundary is chosen by the investigator. Stocks store material or value; flows change stocks. Reinforcing feedback amplifies change; balancing feedback resists it. Delays between cause and effect cause overshoot. Externalities are costs or benefits left out of prices. Trade-offs mean a gain in one dimension can create a loss in another; win-win outcomes are possible but must be demonstrated. Cultural systems include language, values, identity, and practices, and can be affected by environmental change. Economic activity depends on ecosystem services and social trust.
Worked example
A town's water supply comes from a river. Upstream dairy intensification raises farm income and employment (economic), but nutrient runoff feeds algal blooms (environmental). Swimming and fishing decline (social), and iwi lose access to mahinga kai (cultural). A reinforcing loop appears if pollution reduces tourism, which increases pressure for more intensive land use. A balancing loop appears through nutrient caps or riparian planting. The leverage point is the rule governing land use, not just cleaning the water later.
Traps
Listing the four dimensions separately without links; claiming a win-win without evidence; ignoring time delays; assuming economic growth always improves social wellbeing; missing cultural effects because they are not priced.
