Climate refuge: What is it, why are important and examples

A climate refuge is a place that, due to its geographical and climatic conditions, offers a certain protection against the most extreme effects of climate change. These places usually remain relatively stable in terms of temperature, water availability and air quality, even when other regions face heat waves, prolonged droughts, forest fires or frequent floods.

Climate shelters can be urban, rural or natural areas That, due to its altitude, close to bodies of water or abundant vegetation, they manage to soften the impacts of global warming. Some cities, for example, are investing in green infrastructure (such as parks, vegetable roofs or trees in the streets) to become cooler and more resilient spaces in the face of extreme heat.

Climate shelters fulfill a key function in adaptation to climate change. They serve, mainly, to protect people, ecosystems and infrastructure against increasingly extreme weather phenomena. By offering more stable conditions, these places allow:

• Reduce health risks: In times of extreme heat, for example, a climate refuge can avoid heat blows, dehydration or complications in vulnerable people, such as children and adults.
• Increase urban resilience: In cities, having green areas, natural shadow and good space planning helps maintain the lowest temperature, to better drain intense rainwater and cope with extreme events without collapsing.
• Protect biodiversity: In natural environments, climatic shelters allow many species to survive sudden changes in the weather.
• Offer security and quality of life: As some regions become more and more difficult to live, climatic shelters can become destinations where people look for a safer and more stable life.

A climate shelter works thanks to a combination of Natural and human factors That, together, create a more stable and protected environment against the effects of climate change. Its operation is based on minimizing the impact of extreme phenomena (such as heat waves, floods or droughts) and offering safer conditions for human life and the natural environment.

These are some of the elements that explain how a climate refuge works:

• Natural characteristics of the environment: Many climatic shelters are located in areas with geographical advantages: close to bodies of water, moderate altitudes, abundant vegetation or temperate climates. These conditions help maintain softer temperatures and greater water availability.
• Infrastructure adapted to climate: In urban areas, a climate refuge can also be the result of good planning. The use of materials that do not retain heat, green roofs, streets with shade, good natural ventilation and public spaces with vegetation help reduce the so -called “urban island”.
• Efficient water management: Climate shelters tend to have sustainable drainage systems, efficient use of water and natural spaces that absorb excess rain, which reduces the risk of floods or shortage in dry times.

Climate shelters are increasingly important because climate change is no longer a problem of the future: it is happening now. With more frequent heat waves, torrential rains, prolonged droughts and forest fires, many regions of the world are facing difficult conditions to live.

These are some key reasons that explain their importance:

• They protect human lives: In critical moments, such as during an extreme heat wave or a storm, a climate refuge can make the difference between life and death, especially for vulnerable people such as elderly, children or who suffer from respiratory or cardiovascular diseases.
• Reduce pressure on health and emergency systems: By mitigating the extreme effects of the weather, these spaces help avoid saturations in hospitals and reduce the need for emergency interventions.
• Foster more resilient communities: The cities or regions that develop climatic shelters are better prepared to face future crises.
• They preserve biodiversity: In natural environments, climatic shelters are vital to conserve animal and plant species that could not survive in other places affected by extreme temperatures or the loss of habitat.
• They offer just and sustainable adaptation opportunities: Not all people have the means to move or protect themselves from the effects of climate change. Therefore, having accessible and well distributed climatic shelters is also a matter of social equity and environmental justice.

Climate shelters can be found in different parts of the world, and they do not always look the same: some are natural areas little altered by the human being, while others are cities or neighborhoods designed to better adapt to the effects of climate change.

Let’s see some of the best known examples in the world:

Freiburg, Germany

Friburg is known as one of the most sustainable cities in the world. Its urban planning incorporates green ceilings, electric trams, pedestrian streets, solar panels and many wooded areas. All this helps reduce urban heat and to maintain a good air quality.

High lands of Scotland

This region has a tempered climate and abundant vegetation, which makes it an ideal shelter for many animal and plant species. Its low population density and the conservation of natural ecosystems allow better extreme phenomena such as heat waves or forest fires.

Vauban neighborhood, Friburg (Germany)

This neighborhood, considered an ecological model, combines energy efficient housing, accessible public transport, streets with vegetation and shared spaces.

Portland, United States

Portland has implemented nature -based solutions to reduce floods: green roofs, permeable pavements, rainyrs and areas that absorb excess water.

Medellín, Colombia

Medellín, located about 1,500 meters above sea level, enjoys a constant spring climate throughout the year. In addition, in recent years he has opted for “echoci city”: green runners, linear parks and sustainable transport to mitigate the heat island effect.
