"Blue-green infrastructure is not only an ecological necessity but also a source of beauty and inspiration. It has the power to transform cities, creating spaces that are not only functional but also visually appealing, fostering a sense of well-being and connection with nature.”   Herbert Dreiseitl

The European Union (EU) has unveiled its ambitious Climate Adaptation Strategy, placing significant emphasis on the implementation of Blue and Green Infrastructure (BGI) projects.

Definition: Blue Green Infrastructure (BGI) refers to a network of natural and man-made features that provide multiple environmental, social, and economic benefits, particularly in urban areas. It integrates water management with green spaces to create sustainable and resilient environments.

Components of Blue Green Infrastructure:

Benefits of Blue Green Infrastructure:

    • Flood Risk Reduction: BGI features absorb and store stormwater, reducing flood risk and minimizing damage to infrastructure and properties.
  • Water Quality Improvement: Natural features like wetlands and green spaces act as filters, improving water quality by removing pollutants and enhancing natural water purification processes.
  • Biodiversity Conservation: BGI provides habitats, food sources, and movement corridors for diverse plant and animal species, contributing to biodiversity conservation in urban areas.
  • Climate Change Adaptation: BGI helps mitigate the impacts of climate change by reducing heat island effects, improving air quality, and enhancing overall climate resilience.
  • Economic Benefits: BGI attracts tourism, enhances property values, and supports green job creation, contributing to local economies.
  • Social Benefits, Enhanced Urban liveability.
  • Community Engagement and Social Cohesion: BGI projects involve communities in planning, design, and management, fostering a sense of ownership, social cohesion, and community pride.


Challenges way forward

Conclusion: Blue Green Infrastructure holds tremendous potential in creating sustainable and resilient urban environments by integrating nature into the built environment. Embracing BGI as a forward-thinking approach can lead to a greener future, enhancing biodiversity, improving quality of life, and mitigating the impacts of climate change.
