Forest ecosystems of the future will have to cope with very different conditions to those of today. For this reason, researchers at the Technical University of Munich (TUM) state that a strategic approach to forest management is crucial. To this end, the research team has developed iLand: a simulation model that can compute long-term developments of large forest landscapes, right down to the individual tree—including disturbances from bark beetles to wildfires.

Charred tree trunks and blackened soil are typical of the desolation that a forest fire leaves behind. Inevitably, the question arises whether it will be possible to restore a green natural landscape. According to Rupert Seidl, Professor of Ecosystem Dynamics and Forest Management, this is possible, but the “how” decides how much the new forest will benefit the climate, nature and people.

“Today’s forest ecosystems are not particularly well adapted to future climate conditions,” says Seidl. “Over the next decades they will presumably come under increasing pressure from water shortage and insect pests, and may even die off. This is why it makes sense to use measures such as the reforestation of disturbed areas to strategically select tree species and take future developments into consideration.”

A pair of new studies by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the School of Architecture, shed new light on the potential of climate-inspired architectural and urban design proposals, termed “climatopias,” to effectively address climate change challenges. These studies analyze both specific high-profile projects and a broader range of proposals, providing valuable frameworks for evaluating their effectiveness, feasibility, and social justice implications.

The first paper focuses on a detailed analysis of four prominent climatopic design projects. Utilizing a novel evaluation approach, the researchers assessed each project on its effectiveness, justice, and feasibility.

Key findings indicate that for climatopias to serve as viable climate solutions, they must prioritize their embodied carbon footprint, feature affordable and participatory designs, and possess the potential for actual implementation or stimulate critical discourse around decarbonization and adaptation strategies, enriching community engagement in climate resilience. The findings are published in the journal One Earth.

The Arctic is likely to become “ice-free” by midcentury—and could pass that grim milestone much sooner—unless much more is done to combat climate change.

CLIMATEWIRE | By the end of the decade, the Arctic Ocean could see its first ice-free day on record — even with modest levels of global warming.
