resourcecurve

Resourcecurve is a conceptual model used to describe how a finite resource is accessed or extracted within a system over time. It is often represented as a curve that links resource stock or availability to the rate of use, production, or extraction. The term is used across disciplines such as geology, ecology, economics, and operations research to compare different resource scenarios and to understand how constraints, technology, and demand shape resource dynamics.

Common forms of resource curves include Hubbert-like production curves, which depict a rise to a peak followed by decline in extraction rate, as well as logistic or exponential-decay shapes that may model recovery, depletion, or diminishing returns. The specific form depends on factors such as remaining reserves, exploration success, price signals, extraction costs, and policy measures.

Applications include planning and forecasting for mining and energy projects, water resource management, agricultural inputs, and supply-chain risk assessment. Resourcecurve analyses support scenario comparison—such as with or without recycling, substitution, or efficiency improvements—and can help assess when a resource might become constraining.

Limitations include the simplifications inherent in any curve model. Real systems respond to price changes, technical innovation, regulation, and social preferences, which can shift the curve over time. Data quality and uncertainty in reserve estimates also affect reliability.

Related concepts include the Hubbert curve, depletion curve, and resource management.
