When we think of sustainability, we often picture solar panels, bike lanes, or tree-lined streets. But hidden in plain sight are some of the smallest and most powerful allies in the push for a greener future: pollinators.

Bees, butterflies, moths, beetles, and even some birds and bats play a critical role in maintaining ecosystems by enabling plant reproduction. Globally, over 75% of food crops depend to some extent on animal pollination (IPBES, 2016). Without pollinators, the diversity and stability of our food systems—and by extension, our urban ecosystems—would be at serious risk.

Why Pollinators Matter for Urban Sustainability

In cities, pollinators contribute to multiple aspects of sustainability:

• Biodiversity: Supporting pollinators helps maintain diverse plant life, which in turn supports broader ecosystems.

• Food security: Urban agriculture—rooftop gardens, community plots, orchards—relies on pollinators for fruit and vegetable production.

• Climate resilience: Diverse green spaces with native flowering plants can withstand climate shocks better and support ecosystem services like air purification and water retention.

• Human well-being: Pollinator-friendly landscapes—colorful, flowering, and biodiverse—enhance mental health, aesthetic value, and community engagement.

A Decline with Consequences

However, pollinator populations are in steep decline due to habitat loss, pesticide use, pollution, invasive species, and climate change (Potts et al., 2010). Cities, paradoxically, can become both refuges and risks for pollinators, depending on how urban environments are planned.

What Can Cities Do?

Local governments, planners, and residents can take action by:

• Creating pollinator corridors: continuous stretches of flowering plants through parks, roadsides, and green roofs.

• Banning or limiting pesticide use in urban gardening and landscaping.

• Planting native and diverse plant species that bloom throughout the year.

• Including pollinator habitats in urban greening policies, like those promoted in the EU’s Nature Restoration Law.

Final Thought

Pollinators are more than a symbol of spring—they’re a foundation of sustainable urban life. By integrating pollinator-friendly practices into urban design and policy, cities can become not only greener, but also more resilient and life-supporting for all species, humans included.

Yet while the legislative focus often emphasizes biodiversity and climate resilience, a broader question remains largely underexplored: what do urban green spaces really provide to cities and their inhabitants? To answer this, we must look beyond the visible greenery and examine the ecosystem services (ESS) they deliver—benefits that are often overlooked in planning and policy debates.

What Are Ecosystem Services (ESS)?

Ecosystem Services refer to the multiple benefits that natural and semi-natural ecosystems provide to people. According to the Millennium Ecosystem Assessment (2005), these are typically grouped into four key categories:

1. Provisioning Services – tangible goods like food and water. In cities, examples include community gardens or foraging landscapes.

2. Regulating Services – such as temperature moderation, air purification, stormwater management, and carbon sequestration.

3. Cultural Services – non-material benefits like mental well-being, recreation, and social cohesion.

4. Supporting Services – underpinning all others, including soil formation, pollination, and nutrient cycling.

Urban green spaces—whether large parks, pocket gardens, green roofs, or vegetated streetscapes—contribute to all of these in diverse ways. A systematic review by Gómez-Baggethun & Barton (2013) found that urban green infrastructure plays a vital role in regulating urban microclimates, improving air and water quality, and providing psychological benefits.
