Green Infrastructure: Why It Matters and Why It’s Hard to Deliver with Professor Ian Mell

Send us Fan Mail

Professor Ian Mell discusses how green infrastructure has moved from the margins of planning into mainstream conversation. He explains the political, economic and cultural barriers to delivery in the UK, cautions about uncritical reliance on markets and offsets, and highlights lessons from Asian cities where ambitious, large-scale projects and data-driven delivery have driven visible change. The episode explores equity, climate adaptation, placemaking and how to combine technical valuation with everyday lived experience to make green infrastructure work for communities.

Key takeaways

• Green infrastructure is now part of national conversation but delivery and funding remain inconsistent across the UK.
• Economic valuation helps enter conversations with funders but cannot capture all environmental value. Markets and offsets need careful scrutiny.
• Asian cities provide rapid, large-scale experiments in GI that the UK can learn from, particularly on urban regeneration and converting failing infrastructure into green space.
• Lived experience matters. Simple design elements: shade, seating, lighting, bins, playgrounds; often determine whether green space is used and benefits well-being.
• Political will and long-term funding are essential. Short political cycles and fear of failure limit bold local investment.
• Climate adaptation and social justice must be addressed together to ensure equitable access to benefits.
