Built Environment Issues: • Prone to erosion
• Lack of sanitation or potable water infrastructure • Lack of safe, formalized paths • Lack of public play spaces for children in the community Human and Ecological Health Issues: • Delicate “Lomas” fog-fed ecosystem is threatened by urbanization and deforestation • Lack of plant cover increases erosion, exacerbating the already high rates of respiratory diseases in the community • High rates of malnutrition and cardiovascular disease risk • High stress, anxiety and other mental wellbeing issues

• Lack of greenery
COMMUNITY: ELISEO COLLAZOS
• Earthquake prevalent zone
Community Prioritization During a series of participatory workshops, residents identified water security and public greenspace as key priorities. In response, the team undertook two pilot projects between 2013-2015: 1) a fog collection pilot 2) a pilot household garden initiative The FWF’s fog collection system, household gardens and community park build upon these pilot projects and, leveraging the consistent commitment of EC residents, amplify their positive impacts.

PARTICIPATORY DESIGN WORKSHOP
Visioning workshop Common themes include fog collection, water storage and a community park.
Typical fog collection material - shade cloth
New high performance fog collection material - erosion control matting
On-site material testing: Confirmed erosion control material was superior to shade cloth
Researched case studies with a local Peru fog collector NGO

Community prioritized fog collector locations
FOG WATER RESEARCH
Controlled testing: erosion control mat performed significantly better than shade cloth

The full scale fog collection system was implemented in 2015 and 2016. It included 6 large triangular fog collectors.

Longevity of an intervention depends heavily on the community’s ability to maintain the system.

Physical and mental health impacts of household gardens in an urban slum in Lima, Peru Masters of Public Health thesis paper
Conclusions: Improved access to green space in the form of a household garden can significantly improve mental health in a slum setting.
*Follow-up Data Of original gardens, 70% of the households amplified their gardens, with the average owner adding 14 plants. One resident increased by 69 plants, exemplifying individual ownership of the intervention.
FOG WATER FARMS
Results: Twelve months after garden construction, we found significant increases from baseline in all domains of quality of lifeâ&#x20AC;&#x201D;physical (p<0.01), psychological (p=0.05), social (p=0.02), and environmental (p=0.02)â&#x20AC;&#x201D;in overall social capital (p<0.01), and perceived stress (p<0.01). Life threatening experiences decreased compared to baseline significantly (p=0.02). There were no significant changes in parent or partner empathy (p=0.21), BMI (p=0.95), waist circumference (p=0.18), or blood pressure (p=0.66) at 6 or 12 months. Fasting blood glucose increased at 6-months (p=0.04), but this change was not maintained at 12-months (p=0.59).
GARDENS MEASURED IMPACT
Background: Rural poverty and lack of access to education has led to urban migration and fed the constant growth of urban slums on the outskirts of Lima, Peru. These informal settlements suffer from lack of public access to water and sanitation, informal land rights, food and water insecurity, all of which contribute to poorer health outcomes. We explored the feasibility of implementing household gardens using participatory design methods and examined the impact of increased green space on wellbeing.
