The Future of Green Festivals: How Bloom is Setting a Global Standard
As Dublin’s Phoenix Park opens its gates for another year of Bord Bia’s Bloom, the event has become more than just a showcase for horticulture. It’s a bellwether for a global shift in how we conceive of public gatherings. With the festival achieving the prestigious ISO 20121:2024 accreditation for sustainability, the future of major events lies in radical environmental responsibility.

But what does this mean for the future of gardening, community wellness, and climate action? As we look ahead, the intersection of nature and human health is becoming the primary focus for landscape architects and event planners alike.
The Evolution of “Therapeutic Landscapes”
For years, gardens were viewed primarily through an aesthetic lens. Today, we are seeing a massive shift toward “therapeutic landscapes.” At Bloom, the inclusion of gardens dedicated to mental health awareness and cancer support reflects a growing body of research proving that nature-based interventions significantly reduce cortisol levels and improve cognitive function.

Looking forward, expect to see “prescriptive gardening” become a mainstream trend. This involves designing urban spaces specifically to combat the modern epidemic of loneliness and stress. Think of community-led “postcard gardens” evolving into permanent fixtures in urban planning, where prison rehabilitation programs and local biodiversity initiatives share the same green space.
Sustainability as the New Currency of Events
The festival industry is under immense pressure to reduce its carbon footprint. The move toward ISO 20121 certification is not just a badge of honor; it is a blueprint for survival. As event-delivery costs rise—a challenge Bloom organizers have navigated by evolving their ticketing models—sustainability is becoming a cost-saving measure rather than an expense.
Future festivals will likely rely on:
- Circular Logistics: Minimizing waste by sourcing all materials from within a 50-mile radius.
- Biodiversity Net Gain: Ensuring that every event leaves the local ecosystem in a better state than it was found.
- Dynamic Pricing Models: Encouraging early attendance to manage crowd flow and reduce the peak-time strain on infrastructure.
Can Green Tech Save Our Gardens?
From Met Éireann’s 90-year climate data to modern organic farming practices, technology is the silent partner in the garden. In the coming decade, we will see an integration of “smart gardening” tools—sensors that monitor soil health and water usage in real-time—being brought into the public sphere.
