Stadtbäume sind nicht nur schön, sagen Wissenschaftler, sie sind auch obligatorisch | Überdenken Sie städtische Wälder als wesentliche Infrastruktur für Widerstandsfähigkeit, Gerechtigkeit und Artenvielfalt im aktuellen Klimanotstand

Some key points from the news article:

>What makes urban forestry so important? For one, trees significantly cool the concrete jungle by providing shade and releasing water vapor to “sweat.” Patches of greenery also allow stormwater to soak into the ground instead of pooling and flooding — that investment alone will spare cities from economic damage as a warming atmosphere makes rain fall harder. Spending time in parks also boosts mental health, while urban farms produce nutritious food and create jobs. Planting trees, especially native species, also provides shelter and food for fauna. At the same time, vegetation absorbs pollutants, improving air quality for everyone.

>Even for cash-strapped governments, this is an investment proven to yield dividends: A recent report found that for every dollar put into parks and recreation, cities reap $3 in local economic benefits every year. That’s because green spaces encourage people to exercise, supporting public health and reducing the costs associated with sedentary lifestyles. By attracting locals and tourists, parks also spur economic activity as folks filter into surrounding neighborhoods to shop or have lunch. So, while it does take money to plant and maintain this greenery, it’s in a city’s best interests to do so.

>But mayors must also ensure that these domains blossom in an equitable way, the scientists add. Richer areas tend to be much greener, and therefore cooler, than underserved neighborhoods. People who can’t afford air conditioning are at higher risk of the urban heat island effect, or the tendency for the built environment to absorb the sun’s energy all day and release it throughout the night. “Then what’s the cost?” Esperon-Rodriguez asked. “They are missing opportunities, they are missing recreational activities. And if they don’t have air conditioning, then on top of that there is the issue of health.”

>Overall, these campaigns need to be evidence-based, the essay argues. Cities, for example, have to identify not just the tree species that communities prefer, but ones that will actually survive ever-climbing temperatures. It’s not just thinking about increasing the canopy in the near term to meet some goal, but making sure cities are more verdant and safer in the long run. “It’s a way to secure,” Esperon-Rodriguez said, “that whatever we’re planting today is going to survive the next 10, 20 or 50 years.”

Abstract:

>Urban forests are not merely green amenities; they support critical ecosystem functioning and services vital for healthy, resilient cities. Recognising urban forests as core infrastructure is essential to reversing the loss of mature trees, preserving biodiversity, and maintaining liveability amid increasing climate and environmental pressures. Although the benefits of urban forests for climate resilience, biodiversity, and public health are broadly acknowledged, policies to protect and enhance these vital ecosystems are often limited, underfunded, and inadequately enforced. As mature canopy loss today takes decades to be replaced (if ever), immediate and sustained investment is crucial to safeguard urban forests. This urgency reveals four interconnected gaps in current urban forest management and stewardship. First, urban forests require recognition, investment, and maintenance as essential infrastructure contributing to urban resilience, including biodiversity support, and to maximise the delivery of key ecosystem services such as cooling and carbon sequestration. Second, equitable access to greenspaces across all communities must be ensured to redress long-standing social and environmental injustices. Third, integrating urban forests into broader climate and biodiversity governance frameworks is critical to mainstreaming their management and protection. Lastly, resilience must be strengthened through evidence-based management practices responsive to evolving environmental changes and social contexts. These priorities must be complemented with strong legal protections, rigorous enforcement of legislation against illegal tree removal, and robust community engagement supported by integrated urban planning and improved monitoring. Without these, the ecological, social, and economic benefits provided by urban forests will remain threatened. By reframing urban forests as essential living infrastructure embedded in legal, financial, and planning frameworks, cities can become cooler, healthier, more biodiverse, and socially just. This framework offers timely guidance for policymakers to prioritise urban forests within climate resilience and sustainability strategies, securing benefits for current and future generations.

Taking urban ecology is a trip because uou learn that the answer is mind bogglingly simple and accessible and that we are in this mess almost entirely by choice.

Then you’re just stuck with the knowledge but nobody is interested because they’re caught up debating insignificant digressions of the greater problem.
