Saraca Stream certified ANTF Nature Immersion Trail:
Last month, the Saraca Stream in the Singapore Botanic Gardens, designed by Christopher S. H. Long was certified as Asia’s first nature immersion trail by the ANTF (Association of Nature and Forest Therapy). This recognition underpins a fundamental truth: our connection to the natural world is not merely aesthetic—it is a deeply rooted physiological and psychological necessity. Under the lens of Landskiphilia (our innate human attraction to life-supporting landscapes that feel safe, nourishing, restorative, and connected to nature—refer to the paper here), we can understand this connection as a sophisticated feedback loop that has shaped our survival and continues to nourish our well-being today.
From Canopy Clusters to Forest Calm
Our attraction to certain landscape patterns may come from deep within our evolutionary past. Over time, humans learned to respond to environmental signs that helped us survive.
Think about the link between how our ancestors searched for food and why many of us still feel calm and restored in a forest today:
- The Foraging Instinct: To survive in tree canopies and forests, our ancestors had to quickly read busy natural environments. They needed to spot useful signs, such as bright ripe fruit against dense green leaves. Over time, humans became good at noticing these patterns because they helped us find food, stay nourished, and survive.
- The Forest Immersion: Today, the same way our brain responds to nature may explain why forests feel so restorative. Trees release phytoncides, which are natural oils from plants. These oils have been linked to benefits for immunity, blood pressure, sleep, and overall wellbeing. In other words, greenery is not only visually pleasing; it can also affect our body and mind in measurable ways.
This is nature’s feedback loop: the same affinity that once helped our ancestors find what they needed to live may also help us feel restored when we return to natural environments.
The Cognitive City—A Biomimicry of Nature’s Feedback Loop
A Cognitive City is a city that can sense, learn, and respond to the needs of people and the environment. It uses technology, data, and intelligence to improve how the city works over time.
In this sense, the Cognitive City is a form of biomimicry—design that learns from nature. It copies the way nature uses feedback, adaptation, and balance to support life.
In nature, living things constantly respond to their surroundings. Over many generations, this feedback helps species adapt and survive.
A Cognitive City works in a similar way, but through digital intelligence. It can use AI and real-time monitoring to understand how people use the city and how the environment is performing. It can then adjust, improve, and learn over time. For example, it may respond to heat, air quality, movement, comfort, biodiversity, or wellbeing. This is where landskiphilia becomes important: it refers to our natural love for life-supporting landscapes. By understanding this human attraction to healthy natural patterns, the Cognitive City can create urban environments that better support our physical, mental, and ecological wellbeing. As we move toward cities that can sense and respond to us, how can we make sure their digital feedback loops remain connected to the deep human need for nature, restoration, and life-supporting landscapes—i.e. deep-seated, landskiphilic needs encoded in our evolutionary history?
