Abstract [en]

A majority of the world’s cities are situated in or near areas of high biodiversity. Rise in global urban population resulting in rapid urban expansions (larger cities) is a threat to urban biodiversity, which has implications for the ecological health and general well being of humans. The study exploits consistent global land use data to compare 102 cities across the globe on a measure of urban biodiversity, within 15 km and 30 km from the approximate centres of the cities. Cities with high population and higher percentage of land use dedicated to artificial infrastructure recorded lower percentage size reserved for natural habitat, and vice versa. Further testing in regression analysis with birds and plants species as response variables shows a relation with urban extent and size of natural habitat which seeks to promote sustaining ecosystems services. Since urban biodiversity has implications for human ecological health, its indicators must be constantly measured and monitored, while adhering to best practices that conserve nature.
