Landscapes Matter | Sara Bendrick | TEDxSolanaBeach
The speaker argues that modern landscaping treats yards as decorative afterthoughts rather than essential, integrative extensions of the home and community. To improve this, they recommend viewing landscapes through lenses that prioritize natural health, community connection, and ecological sustainability over mere aesthetics or low maintenance. This is shown by citing scientific evidence linking nature views to healing and proposing alternatives to chemical-heavy, water-intensive lawn care.
## Speakers & Context
- Unnamed landscape designer and contractor who also works in the media.
- Has worked and seen yards across the country, observing a disconnect between people and their landscapes.
## Theses & Positions
- Landscapes should transition from being "decorative or supplemental to our homes" to being an "integrative part of our home," weaving together neighborhoods.
- Creating outdoor spaces is beneficial for health: three to five minutes looking at views dominated by trees, flower, and water can reduce anger, anxiety, and pain and induce relaxation.
- The spaces we create affect our emotions, healing, and behavior.
- The greatest barrier to improvement is the public's tendency to prioritize "low-maintenance over everything else."
- Lawns, while beautiful, require intense resources (water, chemicals) and are not always environmentally sensible.
- Improving landscapes can enhance community connection, encouraging walking and increasing property value.
- Care for the environment requires a holistic approach, favoring native plants, organic inputs, and battery-powered tools.
## Concepts & Definitions
- **Landscape:** Beyond decorative elements, the physical space that serves as an essential part of a home's fabric, weaving together neighborhoods.
- **Outward-facing gardens:** Gardens that connect visually to the street, fostering conversation between the home and the street.
- **Inward-facing gardens:** Gardens with barriers, designed to separate the space from the outside, appropriate for busy streets or undesirable external conditions.
- **Woodwide web:** The underground fungal network through which plants communicate by exchanging carbohydrates for minerals.
## Mechanisms & Processes
- **Healing through Nature Views:** Observing nature leads to physiological benefits, such as reduced healing time post-surgery.
- **Community Building:** Well-maintained, outward-facing front yards encourage walking, which increases connectivity within a neighborhood.
- **Lawn Maintenance:** Requires intensive inputs, such as significant water and chemicals, to maintain a visual sign of success.
- **Symbiotic Communication:** Plants use the woodwide web to share resources or signal defense mechanisms against pests.
- **Air Pollution:** Small gas-powered tools emit pollution equivalent to significant vehicular travel, impacting air quality.
## Timeline & Sequence
- Historically, landscapes were used for food or livestock.
- The trend moved toward landscapes being purely decorative/supplemental.
- The lawn became mainstream for the middle class after the invention of the first lawnmowers in the **1830s**.
- The focus needs to shift from aesthetic output to functional, integrated design.
## Named Entities
- **Jane Jacobs:** Renowned urbanist and author who stated, *"Seeks and their sidewalk, the main public space of a city, are its most vital organs."*
- **Deborah Franklin:** Reviewed studies supporting the connection between nature viewing and healing.
- **Roger Olrich:** Environmental psychologist who conducted a study comparing patient healing times based on bedside views.
- **Hous:** Conducted a 2018 landscape survey.
- **Ames NASA Research Center:** Employed Dr. Christine Mesi, who provided data on water use.
- **San Diego Sod Farms:** Provided data comparing cooling effects of different surfaces.
- **California Air Resource Board:** Issued a study comparing leaf blower pollution to vehicular emissions.
- **Fosters Hospital for Small Animals at Tus University Cummings School of Veterary Medicine:** Cited regarding the risks of lawn pesticides.
- **Washingtonia felifera:** The only native palm found in California, which grows far east of the coast.
## Numbers & Data
- Proportion of US covered in lawn: **Almost 2%**.
- Lawn coverage relative to other irrigated crops: **Three times larger**.
- Healing time advantage for tree views: Patients with tree views healed, on average, **one day sooner** and needed **less pain medication** than those with brick wall views.
- Hous 2018 survey respondents: **750 people** surveyed.
- Spent more time outside post-project: **67%**.
- Relaxed or rested more: **63%**.
- Entertained more: **51%**.
- Spent more time with family: **26%**.
- Water required for turf grass (coastal environment): **28 gallons per square foot per year**.
- Water required for turf grass (inland California): **37 gallons per square foot per year**.
- ROI on installing new lawn (according to houselogic.com): **267%**.
- Cooling effect: Lawns can be **30% cooler** than surrounding asphalt and **15% cooler** than exposed dirt (according to San Diego Sod Farms).
- Pesticide risk: Exposure to lawn pesticides can raise the risk of canine malignant lymphoma by as much as **70%**.
- Pollution comparison: A top-selling leaf blower operating for **1 hour** emits pollution equivalent to driving **1100 miles** (Los Angeles to Denver).
- Homeowner use of small engine power in California: **77%**.
## Examples & Cases
- **Uninspired Yard:** Basic placement of a lawn, dog-eared fence, and some shrubs without consideration for function.
- **Outward vs. Inward Gardens:** Illustrating the difference in neighborhood feeling; outward gardens connect visually to the street.
- **Lawn History:** Wealthy families historically afforded extravagant lawns; lawns became mainstream with the middle class after the **1830s**.
- **Artificial Turf Installation:** First seen in the **Houston Astrodome** in the **1960s**, later popular in residential/commercial use in the **1990s**.
- **Natural Communication:** An insect attack triggers a signal from one plant to surrounding plants, prompting them to increase defenses.
- **Resource Supplementation:** Larger family trees can supplement a struggling sapling until it achieves sufficient height for photosynthesis.
## Tools, Tech & Products
- **Lawnmowers:** First invented in the **1830s**.
- **Artificial Turf:** Material composed of nylon or polypropylene fibers, usually placed on compacted base material and secured with nails.
- **Leaf blower:** Small gas-powered tool, cited for its high pollution output.
- **Battery-operated/Corded Tools:** Suggested as alternatives to gas-powered tools for maintenance.
## Trade-offs & Alternatives
- **Lawn vs. Native Grasses:** Choosing drought-tolerant, California native, or no-mo versions of grass over traditional lawns.
- **Artificial Turf vs. Garden:** Artificial turf is considered a "hardcape" or "green carpet," which can contribute to the heat island effect, unlike transpiring plants.
- **Chemical Use vs. Organic:** Opting for organic approaches to gardening and reserving chemical use for limited, necessary applications.
- **Gas Tools vs. Electric Tools:** Switching from gas-powered maintenance equipment to recyclable battery or corded options to reduce pollution.
## Counterarguments & Caveats
- **Low Maintenance Preference:** People often prioritize low maintenance, leading to uninspiring gardens.
- **Lack of Functionality:** The current approach often fails to connect the landscape to family, community, or environment.
- **The "Hardscape" Trap:** Mindlessly using artificial turf or concrete ignores the need for natural cooling and transpiring plant life.
## Conclusions & Recommendations
- Consider landscapes as an integrative, functional part of the home, not just decoration.
- Prioritize creating outward-facing gardens that connect the home visually to the street to improve community feeling.
- Reduce reliance on water-intensive lawns by using low-growing native alternatives.
- Replace chemical inputs with organic gardening methods.
- Switch landscape tools to battery or corded systems to protect air quality.
## Implications & Consequences
- Neglecting landscape integration leads to disconnected, less healthy living spaces.
- Over-reliance on chemical inputs weakens natural systems (the woodwide web) and poses health risks (e.g., canine lymphoma).
- Choosing better design/maintenance practices can positively impact neighborhood value and civic engagement.
