Besides evident urban problems - waste, pollution, etc. - there are an urban system dynamic's problem it is interesting: growing productive ecosystems appropriation destining to satisfy urban metabolism requires in Tandil city, Argentina. We use for calculating it, Ecological Footprint concept (Rees 1996a; Wackernagel 1996), it allow us assess in superficial terms -hectares- food, combustible, forestall products required as well as, direct soil occupation necessary to wastes and dissipate warm absorption. Ecological Footprint there has a deficit around 77.708,9 ha. And it will be 17, 2 times city area to cover urban metabolism requires in the considered period.
Original Abstract
Además de problemas urbanos evidentes -contaminación, residuos, etc.-, existe un problema asociado a la propia dinámica del sistema urbano que es de interés: la apropiación creciente de ecosistemas productivos externos destinados a satisfacer los requerimientos del metabolismo urbano de la ciudad de Tandil, Argentina. Se emplea para su cálculo, la Huella Ecológica (HE) (Rees 1996a; Wackernagel 1996) que permite evaluar en términos espaciales -hectáreas- los requerimientos de alimentos, combustibles, productos forestales y suelo para la ocupación directa; además del espacio necesario para la absorción de residuos y calor disipado. La HE de Tandil resultó ser deficitaria en 77.708,9 ha, y harían falta unas 17,2 veces la superficie de la ciudad para cubrir las necesidades del metabolismo urbano en el período considerado.

Palabras clave: Huella ecológica, metabolismo urbano, ecosistemas productivos, apropiación, Tandil-Argentina.
