چکیده

Neither the classic resource management concept of maximum sustainable yield nor the concept of sustainable development are useful to contemporary, nonanthropocentric, ecologically informed conservation biology. As an alternative, we advance an ecological definition of sustainability that is in better accord with biological conservation: meeting human needs without compromising the health of ecosystems. In addition to familiar benefit-cost constraints on human economic activity, we urge adding ecologic constraints. Projects are not choice-worthy if they compromise the health of the ecosystems in which human economic systems are embedded. Sustainability, so defined, is proffered as an approach to conservation that would complement wildlands preservation for ecological integrity, not substitute for wildlands preservation. Sustentabilidad Ecológica como Concepto de Conservación Resumen: Ni el concepto clásico de manejo de recursos, ni el concepto de cosecha máxima sostenida son aplicables en biología de la conservación contemporanea, no antropocéntrica y ecológicamente informada. Como una alternativa, proponemos una definicion ecológica de sustentabilidad que es mas acorde con la conservación biológica: alcanzar las necesidades humanas sin comprometer la salud de los ecosistemas. Además de las restricciones familiares de costo-beneficio en las actividades económicas humanas, solicitamos agregar las restricciones ecológicas: Proyectos no deberán ser seleccionados si comprometen la salud de los ecosistemas en los cuales se desarrollan actividades económicas humanas. La sustentabilidad, así definida, se sugiere como una aproximación a la conservación que complementaría la conservación de áreas silvestres para la integridad ecológica, sin sustituirla.

Conservation Forum Sustainability: a Dissent

Broadly conceived and considered in its many usages, sustainability has grave defects as a planning goal, particularly when used by conservationists: it confuses means and ends; it is vague about what is being sustained and who or what is doing the sustaining; it is uninspiring; it is little more than Pinchotera conservation (and thus ignores the many lessons learned since then); it need not be...
