The Expert Group on 'Nature-Based Solutions and Re-Naturing Cities' aims at highlighting environmental solutions and actions that are inspired by or copied from nature.

Four principal goals have been identified that can be addressed by nature-based solutions:

• Enhancing sustainable urbanisation through nature-based solutions can stimulate economic growth as well as improving the environment, making cities more attractive, and enhancing human well-being;
• Restoring degraded ecosystems using nature-based solutions can improve the resilience of ecosystems, enabling them to deliver vital ecosystem services and also to meet other societal challenges;
• Developing climate change adaptation and mitigation using nature-based solutions can provide more resilient responses and enhance the storage of carbon;
• Improving risk management and resilience using nature-based solutions can lead to greater benefits than conventional methods and offer synergies in reducing multiple risks.
