A Global Geospatial Ecosystem Services Estimate of Urban Agriculture

Potential yield (tonnes) from UA, by country, based on the MCD12Q1 urban mask.

“For the first time, we have a data-driven approach that quantifies the ecosystem benefits from urban agriculture. Our estimates of ecosystem benefits show the potential for millions of tons of food production, thousands of tons of nitrogen sequestration, billions of kilowatt hours of energy savings, and billions of cubic meters of avoided storm runoff.”

Abstract

Though urban agriculture (UA), defined here as growing of crops in cities, is increasing in popularity and importance globally, little is known about the aggregate benefits of such natural capital in built-up areas. Here, we introduce a quantitative framework to assess global aggregate ecosystem services from existing vegetation in cities and an intensive UA adoption scenario based on data-driven estimates of urban morphology and vacant land. We analyzed global population, urban, meteorological, terrain, and Food and Agriculture Organization (FAO) datasets in Google Earth Engine to derive global scale estimates, aggregated by country, of services provided by UA.

Excerpt:

a modular farming system called GrowMore, which allows people living in cities to build and maintain mini farms made from a series of simple plywood planters.

Designed by danish firm Husum & Lindholm Architects, Growmore structures can be assembled using six plywood components. The system is designed for people living in cities to utilise unused urban space for local food production.

“Growmore is an urban gardening modular design that enhances our awareness on local production,” the architects said. “It consists of very few elements, which makes it possible to build in any given context.”?

Vancouver BC: Tax breaks for developers who put in community gardens

Temporary Vancouver community garden is set up where a gas station used to be.

… small businesses, struggling to stay alive, get pounded to the point of facing failure, while major developers get significant tax reductions for doing nothing except allowing folks to grow a few carrots or potatoes on their patch of land?

Excerpt:

Wesgroup is a development company owned by a guy named Peeter Wesik. Last year Wesgroup purchased five gas stations, including one in my neighborhood at West Fourth and Macdonald. By October the buildings were demolished and removed, the ground surface was covered with gravel and the property was surrounded with a chain link fence.

Thanks to a deal Wesgroup made with a not-for-profit outfit called Shifting Growth Society, wooden planter boxes filled with soil were placed on the property. In my particular ’hood there were 100 boxes mostly three feet by four feet in size.
