GEOG 280 Lecture Notes - Lecture 5: Ecosystem Services, Ecosystem Management, Ecosystem Diversity
Document Summary
Arise from both consumptive and non consumptive resource uses. Always have implications for ecosystem condition and integrity, as well as for resource use opportunities and constraints. Consumption / degradation of resources, including ecosystem services. Stocks or ows of materials or energy, processes, or conditions that may be used to meet needs or satisfy wants. Depend on a changing combination of needs/wants, perception/awareness, technological capacity. Non renewable: typically considered as nite quantities of material that are depleted as a consequence of use. Renewable: typically considered as resource which self renew or can be replenished or restored. Perpetual: continuously available, although rates of ow will be nite and may be variable or cyclical. Recognition of bene ts that human obtain as a result of ecological processes and condition. We deliberately manipulate or inadvertently alter ecosystems. For the most part, however, what we are really doing is managing human behaviour.
