A 60% Reduction in the Connection Between Humans and Nature Over 200 Years: Can Cities Increase "Greening" Tenfold? Exploring the Science of Connecting Families with Nature

1) A 200-Year Decline: Numbers Tell the Story of "The Extinction of Experience"

"How connected are we to nature?"—a seemingly vague question that the latest research answers with concrete numbers. Professor Richardson from the University of Derby in the UK has recreated the trajectory of "connection with nature" from 1800 to the present using an agent-based model (ABM) that incorporates the progression of urbanization, the degradation of local biodiversity, and the structure that makes it difficult for nature-oriented values to be passed "from parent to child." The result showed a "60% decline." The frequency of nature-related words appearing in books followed the same curve, showing a 60.6% drop by 1990 (currently recovering to 52.4%).The Guardian

2) "Connection" is Not a Mood: Determined by Parents and Urban Structure

The crux of this research is treating the psychological construct of "nature connectedness" as a socio-ecological system driven by the amount of greenery in urban areas (opportunity), people's orientation towards paying attention and attachment to nature, and the "inheritance" between parents and children. The model depicts a negative feedback loop where urbanization narrows "opportunities," and as parents become less able to convey a nature-oriented stance, the initial values for the next generation also decrease.MDPI

3) 30% is Not Enough: What is Needed is "10 Times" the Greenery

When asked, "Will increasing parks solve the problem?" the answer is "probably insufficient." Sensitivity analysis by the research team indicates that even a "30% increase" in biodiversity-rich green spaces in urban areas is not enough to reverse the trend. What is needed is a "tenfold scale." In other words, it's not about point parks but envisioning the entire city as a "green infrastructure." The research also suggests that if education and urban planning can be transformed within the next 25 years, the "connection" that has entered recovery mode could become self-sustaining (self-reinforcing).The Guardian

4) 4 Minutes and 36 Seconds a Day: What Modern "Normalcy" Brings

The Guardian introduced a measurement showing that the average time people in Sheffield, UK, spend in natural spaces is only "4 minutes and 36 seconds a day." The daily sequence of commuting—indoors—smartphones reduces the "denominator" of natural experiences and amplifies intergenerational disconnection. This is a problem of "structural life design" that also affects mental health and environmentally considerate behavior.The Guardian

5) Reactions on Social Media: Hope, Anxiety, and Practice Intersect

This news sparked discussions on social media. In environmental communities, there were many voices of empathy that "the normalization of urban life is eroding natural experiences," while simple questions like "How do you quantify 'connection'?" were also prominent. On a Reddit thread, experiences were shared from outdoor education sites, stating, "Even children who are initially afraid of soil and insects change with repeated experiences. If parents take them, restoration is possible." Below are some excerpts (paraphrased and summarized).

"This research incorporates elements of urbanization and intergenerational inheritance. It's interesting but also seems subjective."(Questioning the measurement method)
"Middle and high school students are afraid of soil. But by the end of the year, they change. Parents, take your children camping."(Voices from the field)
"Not surprised by indoor work. There's no time to go outside."(Problem of life structure)

6) "Events" Alone Won't Bring It Back: What Should Be Designed

Short-term nature experience campaigns (e.g., #30DaysWild) contribute to mental improvement but have limited power to stop intergenerational disconnection. What works is "early and repeated." At the preschool and elementary school stages, incorporating "everyday" nature experiences involving parents and children into the curriculum and taking them home like homework is the design. Psychological research suggests that "contact," "emotion," "meaning," "compassion," and "appreciation of beauty" are the main pathways that extend "connection" rather than knowledge. The teaching materials should lean towards experiences that can be savored with the five senses rather than "name memorization drills."The GuardianPLOS

7) Translating Urban Planning: Making the "10 Times" a Reality

"Ten times" may sound exaggerated, but in urban ecology, the idea of treating all public/semi-public spaces such as street trees, schoolyards, parking lots, rooftops, balconies, setbacks, and riverbanks as a "network of nature" simultaneously is becoming mainstream. For example, the "3-30-300" guideline—seeing three trees from home, a district canopy cover of 30%, and a park within 300 meters—has been validated to some extent from the perspective of residents' health and resilience.MDPI

8) Implications for Japan: "Family Design" and "Redistribution of the City"

In Japan's hyper-urbanized society, weekday commuting and indoor work easily create "zero nature minutes" days. The countermeasures are twofold.
(1)Family × School: Weekly "outdoor homework," forest kindergarten-type programs in nurseries, parent-child nature observation meetings in collaboration with PTAs.
(2)Redistribution of the City: Greening and biotope creation of schoolyards, tree belts along school routes, standardization of rooftop gardens, restoration of flora and fauna corridors in rivers and waterways, mandatory permeabilization and peripheral planting of parking lots.

These are not "events" but tasks to rewrite the OS of living.

9) Finally: Words Have Begun to Return

There is also good news. The frequency of nature-related words has shown a slight recovery trend in recent years, suggesting a possible "revival of sensitivity" on the cultural side. The important thing is to bridge the revival of words to the revival of experiences. Can parents pass on opportunities to pay attention to nature to their children, and can cities offer them to residents as "everyday" occurrences? This is where the challenge lies.The Guardian
