The growth of cities may cause biodiversity to decline by fragmenting or destroying large areas of natural habitat on which many species depend. The rising human population is driving the expansion of urban areas and increasing the demand for natural resources such as timber and fossil fuels.
Why does urbanization decrease biodiversity?
This adds up to a big loss of biodiversity, because species richness (number of species) at a site is globally on average 50% lower at urban sites than in intact natural habitat. However, the indirect effect of urban growth on biodiversity is likely far greater than the direct effect.
How does Urbanisation impact biodiversity?
The process of urbanisation has serious consequences for biodiversity. First, and most obviously, urban development permanently replaces natural ecosystems. … Human populations often occupy the places where biodiversity tends to be richest.
How does urbanization affect the ecosystem?
The impact of urbanization processes on ecosystem services is complex in the region, both positively and negatively. Overall, urbanization led to a decline in natural habitat, water retention, soil conservation, and carbon sequestration by 2.6%, 1.1%, 6%, and 3.4%, respectively.
Are urbanization and biodiversity incompatible?
Urbanization is one of the most intensive and rapid human-driven factors that threat biodiversity. … The mean functional originality increased with urbanization at both local and regional scales, although this increase vanished in communities with high species richness.
What is urbanization on biodiversity?
Urbanisation has an important impact on biodiversity, mostly driving changes in species assemblages, through the replacement of specialist with generalist species, thus leading to biotic homogenisation. Mobility is also assumed to greatly affect species’ ability to cope in urban environments.
How does Urbanisation cause habitat destruction?
Urbanisation leads to habitat fragmentation, where larger continuous habitats are divided into smaller unconnected patches. It also causes habitat loss, through an increase in roads and buildings that are not producing any biomass. This exposes wildlife to new man-made stress.
How does urbanization affect wetland plant diversity?
During the rapid urbanization, the process of the wetland environment in watershed change becomes more complex due to the combined influence of natural and human factors. … Urbanization also reduces native plant species and increases introduced plant species.
Why is urbanization a problem?
Some of the major health problems resulting from urbanization include poor nutrition, pollution-related health conditions and communicable diseases, poor sanitation and housing conditions, and related health conditions. … Urban dwellers also suffer from overnutrition and obesity, a growing global public health problem.
