El desafío

Our City Forest was formed in part as a result of research documenting the benefits of the urban forest, and has worked to plant trees in under-resourced communities in and around San José to offset the impacts of climate change on air quality, human health, and other environmental factors. The human health benefits of increased canopy cover are well-established, and there has been substantial research investigating the interactions between canopy cover and factors such as air quality and urban heat islands.

Across the San José metropolitan area, air quality, canopy cover, and other environmental factors vary significantly from neighborhood to neighborhood. The short- and long-term consequences of living and working in areas of poor air quality and within urban heat islands are well-known; however, in order to understand how these varying environmental conditions impact neighborhoods differently throughout urban communities, the environmental and human health data must be available at the neighborhood scale.

The goal of this project is to establish what information already exists for this area and ensure that this baseline data is accessible in a centralized location. That baseline data can then be used to explore the relationships between canopy cover, air pollution, and human health outcomes, and to communicate those relationships to both local communities and municipal government.  The process of gathering data and preliminary data exploration may identify data gaps (e.g. an uneven distribution of air quality sensors) that could be addressed in future studies.

 Project Outputs

  •       Phase 1: Exploring Existing Research

o   Compile existing datasets

o   Create preliminary data summary

o   Create data exploration tool   

  •       Phase 2:

o   If there is sufficient data, conduct a more quantitative analysis of the existing data

o   If there is not sufficient data, create a report of data gaps and/or write up project proposal to fill those gaps
