In New Orleans, the Upper Ninth Ward’s Bunny Friend neighborhood residents are experiencing poor air quality associated with urban blight and industrial development, and high summer temperatures due to a shifting climate and lack of shade.  Trees can play a role in reducing these problems. This study will help quantify the current impacts of trees in the neighborhood and help identify ways to increase their impact in the future.  Our results will be communicated to residents, project funders and policy makers to help increase the density of green infrastructure in New Orleans and the benefits it provides.

Description

In New Orleans, the Upper Ninth Ward’s Bunny Friend neighborhood is prone to problems associated with its location and residents’ relatively low socio-economic status.  The neighborhood is located in a location that is bordered by the Mississippi River, the Industrial Canal and industrial developments (e.g. docks, freight trains, barges).  This location near industrial development has resulted in a high amount of pollution resulting from these activities.  Furthermore, the neighborhood’s location near waterways and low elevation have made the area prone to flooding.  Most recently, Hurricane Katrina resulted in significant flooding in New Orleans. The economic impacts of this flooding and high likelihood of future flooding has meant that many industrial and residential properties have been abandoned resulting in an increase in blighted properties.  Furthermore, the hurricane resulted property damage and tree loss due to blow downs and wariness of residents to replant.

These challenges have meant that Bunny Friend’s residents are adversely impacted by these environmental problems.  In particular, residents experience poor air quality associated with urban blight and industrial development, flooding caused by poor drainage and intense rain events, and high summer temperatures due to a shifting climate and lack of shade. In cities, trees can provide a multitude of benefits for residents that affect their well-being.  Trees can improve air quality by intercepting particulate matter, reduce flooding by increasing water infiltration, reduce heat island effect by providing summer shade. However, for these benefits to accrue trees need to be present, and in Bunny Friend trees are not widely present.  Consequently, efforts have been undertaken to promote trees and other green infrastructure in the Ninth Ward. However, these efforts have not been as successful as desired.  In Bunny Friend, there is a perception that trees can help improve the well-being of residents but little is known about the current environmental conditions (air quality and heat island effect), the sources of these issues, the trees’ impacts on resident well-being nor the potential impacts of increasing the number of trees.

 

The Project

This study will help quantify the current and future impacts of trees on the well-being of Bunny Friend’s residents describing the current conditions in the area and using this information to help guide future efforts.  Ultimately, the community would like this project to help form a foundation for future efforts to increase green infrastructure and reduce the adverse impact of blight in the Upper Ninth Ward by quantifying the impacts of blight and trees.  Although we anticipate that the research project will be modified as a part of our collaboration, we envision that this research will be completed with components conducted by scientists and community members.

The research team will help to answer questions of interest to the Bunny Friend Community.  Different members of the research team will be responsible for components of the project.

The scientist collaborators will help to answer the following questions:

  • What is the current status of air quality (particulates, chemical, mold) in the Bunny Friend neighborhood?
    1. Based upon the composition of air quality, what are the likely sources of poor air quality?
    2. Where is the air quality relatively better and worse within the neighborhood? Are there hotspots present?
  • What is the current status of the heat island effect in the Bunny Friend neighborhood? Is crowdsourced data available?
    1. How does Bunny Hill differ from other neighborhoods?
    2. Where is the heat island effect relatively stronger within the neighborhood? Are there hotspots present?

The community members will help to answer the following questions using a modeling approach.

  • Use iTree (itreetools.org) or other comparable software to model the current tree cover of the Bunny Friend neighborhood.
    1. Based upon the observed tree cover, what are the current contributions of trees for improving air quality?

Together the scientists, community members and Thriving Earth Exchange fellow will work together to analyze and articulate the role that trees may have in addressing air quality and heat-based challenges:

  • Identify and quantify the contribution that trees could make to help the community achieve their desired air quality and temperature goals.
  • Identify areas where trees and/or other actions (e.g., blight removal) could provide the biggest contribution to the neighborhood.
    1. Communicate this prioritization to municipal agencies and funding agencies to help them with decisions they make to address blight and heat island effects.
    2. Communicate the findings and potential for trees and green infrastructure to improve community well-being to neighborhood residents, incorporate into outreach materials

Through this research collaboration, it is expected that the findings will be used to provide a basis for future efforts to increase to increase green infrastructure.  These impacts will be two-fold, providing justification for efforts to secure funding or policies to promote green infrastructure and emphasizing the positive impact that green infrastructure could have on the well-being of neighborhood residents.

 

Timeline and Milestones

The project is focused on understanding the dynamics of the heat island effect and air quality. For this reason, data collection will need to be gathered through the hottest time of the year, as well as times when there are varying weather conditions (wind, humidity, precipitation). At minimum, we expect data will likely be collected for 6 months, but ideally longer.  In order to gather data over the summer, sampling will need to start as soon as possible; by April temperatures are hot enough for the heat island effect to be apparent.  It is likely that the timeline and milestones will change as the project becomes more refined.

  • Timeline:
    • Identify Scientists Match: As soon as possible
    • Begin Sampling: Early April 2021
    • Conduct i-Tree analysis: April-June 2021
    • Conclude Sampling: November 2021 (expected)
    • Analyze/combine data and Final Products: April 2022 (expected)
