This era is defined by urbanization. Over one third of world’s human population is expected to be live in cities by 2050. The estimated urban areas for the future occupancy have not yet been built. However, the design and quality of future cities, evolution of today’s society will become turning points of the well being of billions of people. The upcoming decades are expected to witness a dramatic reduction in biodiversity, a phenomenon linked to what scientists are calling the Sixth Mass Extinction. This mass extinction is characterized by an accelerated rate of species loss, primarily driven by human activities such as deforestation, pollution, climate change, and over exploitation of natural resources.
Cities are centers of social, economic, and innovative activities, but the rapid urbanization poses significant threats to biodiversity. Urban leaders have a crucial role in protecting both their citizens and the natural systems they rely on. Traditionally, urban planning has overlooked biodiversity, while conservation efforts have often ignored urban areas. Recognizing the mutual benefits of integrating nature into urban environments can support biodiversity and enhance the quality of life. Therefore, it's essential to design cities that preserve ecosystem services and include urban areas in broader conservation strategies.
What is Urban Biodiversity?
Urban biodiversity can be defined as the variety of living organisms, including their genetic variations, as well as the multiplicity of habitats in and around dense human settlements. Biodiversity, short for "biological diversity," represents the multitude and variability of living organisms within a specific area. It underpins all essential natural resources we rely on for survival, including food, clean water, medicine, and shelter. However, human activities are exerting increasing pressure on the planet, consuming resources at an unprecedented rate, thereby endangering the Earth's rich biodiversity.
The Vital Role of Urban Biodiversity in Enhancing City Life
Urban biodiversity and nature are essential to people for a multitude of reasons. Access to green spaces and natural environments in cities significantly enhances both mental and physical health by reducing stress and encouraging physical activities like walking and jogging. These natural areas also contribute to a higher quality of life by improving the aesthetic appeal of urban settings and fostering community interaction and social cohesion. Environmentally, urban biodiversity plays a crucial role in improving air quality, regulating urban temperatures, and managing stormwater. Economically, proximity to green spaces can increase property values and attract tourism. Additionally, urban nature provides invaluable educational opportunities, raising environmental awareness and offering a platform for scientific research and innovation. From preserving habitats and supporting pollinators to holding cultural and recreational significance, the benefits of integrating nature into urban areas are profound. Therefore, it is vital to incorporate biodiversity into urban planning to ensure sustainable and liveable cities for future generations.
