What is the urban metabolism model?
What is the urban metabolism model?
Urban metabolism is a model to facilitate the description and analysis of the flows of the materials and energy within cities, such as undertaken in a material flow analysis of a city. Urban metabolism provides a unified or holistic viewpoint to encompass all of the activities of a city in a single model.
Who coined urban metabolism?
More than a century later, urban metabolism studies resurfaced again. In 1965, geographer and engineer Abel Wolman theorized a hypothetical one million people city and analyzed its flows, describing its inputs and outputs (Wolman 1965).
Why urban metabolism?
Urban metabolism, used to analyze how urban areas function with regard to resource use and underlying infrastructures, helps us understand the relationship between human activities and the natural environment.
What is metabolism city?
Urban Metabolism is a multi-disciplinary and integrated platform that examines material and energy flows in cities as complex systems as various social, economic and environmental forces shape them.
What is urban material flow?
In this study, we apply urban material flow analysis, which determines the flows of inputs (water, energy, food and others) and outputs (wastewater, air pollution, wastes and others) to the city of Bogotá, Colombia to determine the relationship between demand for resources and the environmental impact of outputs.
What are major approaches for assessing urban metabolism?
Among urban metabolism studies that employ an energy-material flux approach, widely used quantification methods include material flow analysis (MFA), mass balance, and, increasingly, the joining of life cycle assessment (LCA) to UM.
What is urban political ecology?
Urban political ecology seeks to understand the ways in which our urban environments are produced and reproduced, focusing on questions such as who decides, how they decide, who benefits and who loses.
Why is urban ecology important?
Urban ecology promotes resilient and sustainable urban spaces where humans and nature coexist. When integrated in the right way, it can help in decreasing the air and water pollution while enabling new ways of food production, transportation, and housing for people as well. ‘
Is the concept of urban metabolism useful for planning practice?
It is argued that urban metabolism should be evaluated within planning practice, different metabolic components should be assessed at different scales, the measurement of these components should be selective and balance complexity and pragmatism, and that land should be reinforced within the metabolic framework and be …
What is political ecology theory?
Political ecology is a field within environmental studies focusing on power relations as well as the coproduction of nature and society. Theoretical inspirations are taken from different sources such as political economy, poststructuralism, and peasant studies.
What is urban ecology?
Because of its interdisciplinary nature and unique focus on humans and natural systems, the term “urban ecology” has been used variously to describe the study of humans in cities, of nature in cities, and of the coupled relationships between humans and nature.
What does urban ecology include?
Urban ecological systems include individual organisms, populations, communities, and landscapes, as well as buildings and infrastructure. Urban ecology further recognizes specific urban ecosystems as a part of the global biogeochemical, economic, and human demographic system.
