Urban Ecology : CABI : 9781789242607 : 1789242606 : 13 Nov 2020 : Today, 55% of the world's human population lives in urban areas. By 2030, up to 90% of the global human population will live in cities and the global population is expected to increase by 68% by 2050. Although land cover categorized as "urban" is a relatively small fraction of the total surface of the Earth, urban areas are major driving forces in global environmental change, habitat loss, threats to biodiversity, and the loss of terrestrial carbon stored in vegetation biomass. These and many other factors highlight the need to understand the broad-scale impacts of urban expansion as it effects the ecological interactions between humans, wildlife and plant communities. In a series of essays by leading experts this book defines urban ecology, and provides much-needed focus on the main issues of this increasingly important subdiscipline such as the impacts of invasive species, protecting pollinators in urban environments,
