overudvinding

Overudvinding, or overextraction, is the extraction of natural resources at a rate that exceeds the capacity of natural systems to replenish them or to yield economically over the long term. While the term is often applied to groundwater, fisheries, forests, minerals, and fossil fuels, the core issue is a mismatch between resource removal and regeneration or renewal.

Causes of overudvinding include rising demand and price incentives, technological advances that lower extraction costs, weak governance or unclear property rights, subsidies that support extraction activities, and short-term planning horizons that ignore long-term sustainability. Market failures and high external costs can also encourage excessive removal, especially when ownership or usage rights are not clearly defined or enforceable.

Consequences are multidimensional. Resource stocks become depleted, ecosystems suffer disruption, and biodiversity can decline. Physical impacts may include water table drops, land subsidence, soil degradation, and habitat loss. Economic effects include higher production costs, price volatility, reduced future income streams, and social disruption in communities dependent on the resource. Indicators of overudvinding include a falling stock-to-renewal ratio, extraction rates exceeding natural replenishment, declining yields, and rising marginal costs of extraction.

Management and policy approaches seek to restore balance and prevent irreversible damage. Strategies include setting sustainable yield limits, licenses and quotas, protected areas, monitoring and enforcement, price or tax instruments, subsidies reform, recycling and substitution, and international cooperation for shared resources. Precautionary and adaptive management, along with clear property rights, are recognized as core elements to reduce the risk of overudvinding.
