## Quick Overview

Sara Edwards argues that integrating nature into urban life, specifically through projects like restoring the desert-like spaces at the Liceo Nuevo Amanecer in La Florida and the Museo Taller in Barrio Yungay, is crucial for collective well-being, yielding measurable benefits like a 20% reduction in depression and anxiety, improved cognitive development in children, and a 2°C temperature reduction in Medellín, emphasizing that nature is a vital engine for urban, social, and ecological regeneration.

**Key Points:**
- By 2050, 70% of the world's population will live in cities, necessitating nature-based solutions for urban health.
- Restoring a dusty, 250-square-meter plot at Liceo Nuevo Amanecer in La Florida resulted in a lush green space within 10 months (July 2024 to March 2025).
- In the Museo Taller in Barrio Yungay, Santiago, a former trash dump was transformed into a biodiverse ecosystem, showing a direct link between nature and community well-being.
- Exposure to nature reduces depression and anxiety by 20% (Source: Urban Mind Project, King's College London) and promotes cognitive development in children (Source: ABCD Study, Georgia University).
- Urban greening projects can lower ambient temperatures by up to 2°C in urban heat islands like Medellín, Colombia (Source: World Economic Forum).
- The users of the forest at Casa del Encuentro are primarily men (51%), followed by children/babies (26%) and women (23%), indicating that men are actively engaging with these restored spaces.
- Edwards concludes that nature is a powerful engine for urban, social, and ecological regeneration, urging the audience to actively reclaim and integrate nature into their environments.

**Context:** Sara Edwards presents her work focusing on the vital role of nature in urban environments, arguing that integrating natural spaces into cities is essential for human health and ecological balance, especially as urbanization accelerates globally. She shares concrete examples from Chile, such as transforming barren schoolyards and neglected urban lots into thriving green spaces, demonstrating the tangible positive impacts on mental health, child development, and urban climate regulation.

## Detailed Analysis

Sara Edwards begins by projecting the UN statistic that 70% of the global population will reside in cities by 2050, framing the urgency for integrating nature into urban planning. As a designer, she has dedicated her life to connecting with nature, leading her to projects in places like Pirque. During the pandemic, she connected with Magdalena, the founder of Bosque, who was experimenting with a Japanese method to rapidly accelerate native forest growth. Edwards notes that the success of this project in Magdalena led to requests to replicate the method elsewhere. She then presents compelling evidence, supported by studies, showing that access to nature reduces depression and anxiety by 20% and boosts cognitive development in children. Furthermore, urban greening can lower city temperatures, citing a 2°C reduction in Medellín, Colombia. Edwards contrasts the barren, dusty lot of the Liceo Nuevo Amanecer in July 2024 with its transformation into a lush, flowery space by March 2025, and similarly shows the transformation of a trash dump into a vibrant garden at the Museo Taller in Barrio Yungay, Santiago. She highlights that these projects provide shared, secure spaces for community bonding and activities like parenting and play, which were previously absent in the derelict sites. The talk concludes with an invitation for everyone to recognize nature as a fundamental part of collective heritage and as a powerful engine for urban, social, and ecological regeneration, urging people to open their eyes and actively integrate nature into their surroundings.

### Introduction and Urbanization Context

- Sara Edwards introduces herself as a designer passionate about nature
- She cites the UN projection that 70% of the world will live in cities by 2050
- She describes meeting Magdalena, who was accelerating native forest growth using a Japanese method.

### Quantifiable Benefits of Nature

- Evidence shows a 20% reduction in depression and anxiety due to nature contact
- Nature improves cognitive development in children
- Urban greening can lower city temperatures by 2°C (Medellín example).

### Case Study 1

- Liceo Nuevo Amanecer: Shows before (July 2024, dusty field) and after (March 2025, lush garden) transformation of a schoolyard
- This project was realized through private funding.

### Case Study 2

- Museo Taller, Barrio Yungay: Shows the transformation of a former dump into a green space
- This space serves as a community hub, providing areas for play, social connection, and support for parenting.

### User Demographics and Conclusion

- Pie chart shows 51% of users are men, 26% children/babies, 23% women
- Edwards emphasizes that nature is a key driver for ecological and social regeneration, urging collective action to integrate it into the urban fabric.
