Nature Conservancy supports greenspace
The Georgia chapter of The Nature Conservancy has been formulating a plan for one of the city’s potential challenges — its water supply.
Part of TNC’s North American Cities program, which emphasizes a greater role for nature in urban settings, the plan promotes greenspace as an alternative to traditional stormwater infrastructure, like costly culverts and drains. TNC advocates reintroducing natural buffers while protecting existing ones. This “green” infrastructure helps decrease urban runoff and also reduces the amount of pollutants entering local waterways.
Aspects of the plan were outlined in the most recent issue of the NASA Science newsletter.
“The spatial analysis with the NASA DEVELOP team has been really valuable in that it helped us to really think about what are the criteria that we want to use when prioritizing places that will work,” said Sara Gottlieb of TNC. DEVELOP is a national training and development program for individuals to gain experience applying Earth observations through 10-week interdisciplinary projects with state and local governments and other organizations.
DEVELOP teams integrated data from Landsat and Terra into land-use models to locate reforestation targets as well as identify locations that impacted local water quality. The teams applied the results to create a land-use prioritization map of metropolitan Atlanta’s major watersheds.
