Nature in the city: Fighting biodiversity collapse

Cities are often viewed as concrete barriers to nature. Yet rewilding urban spaces offers a powerful way to reverse biodiversity collapse.

The Biodiversity Crisis

Rapid urban growth has destroyed habitats and fragmented ecosystems. Species loss accelerates as cities expand, but thoughtful design can turn this around.

Core Rewilding Approaches

Effective strategies focus on restoring natural processes inside city boundaries:

• Plant native species in parks, gardens, and verges
• Build green corridors linking isolated habitats
• Install living roofs and walls for pollinators
• Reduce mowing and pesticide use to allow natural succession

Benefits for Nature and People

Rewilding supports declining wildlife while improving city life. Cleaner air, cooler temperatures, and better mental health are immediate human gains.

Inspiring City Examples

Singapore links parks with wildlife corridors, while London and Berlin have transformed vacant lots into thriving meadows. These projects show measurable increases in bird and insect populations.

Challenges and Solutions

Limited space and public skepticism remain hurdles. Education campaigns and multi-use green designs help overcome resistance.

A Path Forward

Cities hold untapped potential to become biodiversity strongholds. Coordinated action among planners, communities, and scientists can make urban rewilding a global success story.
