What are the impacts of urbanization on geographic landscapes?

Urbanization profoundly impacts geographic landscapes by transforming natural environments into urban areas. This process includes the following effects:

Key Facts

• Urban areas occupy about 3% of the Earth's land surface yet house more than 55% of the global population (UN, 2022).
• Urbanization is projected to increase, with an estimated 68% of the world’s population living in cities by 2050 (UN, 2018).
• Approximately 80% of global greenhouse gas emissions originate from urban areas (World Bank, 2021).
• Land use change due to urbanization can lead to loss of biodiversity, with urban areas often being biodiversity 'deserts'.

Examples or Use Cases

• The expansion of cities like Tokyo and New York has led to significant changes in local climates, known as urban heat islands.
• The construction of infrastructure such as roads and buildings often leads to habitat fragmentation, impacting local wildlife.

Common Mistakes / FAQs
