摘要:The objective of this article was to carry out a historical review of the emergence, definitions, and approaches of Urban Ecology. To carry out the research, mainly articles published in national and international academic journals were used. Urban Ecology was created in 1920 by the Chicago School, emerging from the need to understand the dynamics of how cities function, addressing human changes in urban areas and their interaction with natural ecosystems and the built environment. Research in Urban Ecology can be strictly biological (Ecology in the City), or have an interdisciplinary approach with the interaction of natural and social sciences (Ecology of the City). The Urban Ecology approach interdisciplinary is essential for the promotion of ecological and socio-economic sustainability in urban areas, serving as a basis for the establishment of strategies and Public Policies for planning and sustainable management of cities.
