Energetic analysis of environmental sustainability in the municipality of Palmira (Colombia)
A rising global urban population, increases the demand for natural resources for a certain quality of life. This creates negative impacts on natural ecosystems and the survival of other species. For this reason, it is necessary to measure the state of cities as ecological systems with the purpose of prioritizing environmental management, in accordance to sustainable development. To this end, there exist methods of chrematistic evaluation which exclude the work of nature to provide environmental services that promote environmental sustainability. This study investigated models that foster environmental accounting and that integrate natural and urban ecosystems. The most original proposal came in the form of emergetic synthesis, based on thermodynamic concepts. The municipality of Palmira was chosen as the study area, known as Techno-ecosystem, and applied a five-phase methodology, based on the emergetic synthesis method. Calculating the rate of emergy production - EYR with 1.46, Environmental Load Index - ELR with 3.2 and Environmental Sustainability Index - ESI with 0.46. The analysis indicates that environmental sustainability and the generation of real wealth is limited by current land use, and can be improved with better use of this resource, through a transversal management process. Furthermore the Techno-ecosystem is subject to the social metabolism of the city of Cali and therefore the demand for imported goods and urban land use will increase, reinforcing the need for environmental management policies , as well as the need to apply to the municipality as Emerging City.
