UPAF contribution to climate change mitigation, adaptation and cobenefits Mitigation: • Reducing food miles, energy use and GHG emissions by replacing food imports with food grown in the city-region • Enhancing carbon sequestration and storage in urban forestry • Reducing methane emissions from landfills and energy use in fertiliser production by productively re-using urban organic wastes
UPAF contribution to climate change mitigation, adaptation and cobenefits Adaptation • Reducing Urban Heat Island Effect by increasing surface of green area and tree cover • Reducing incidence of floods by enhancing storm water infiltration and reducing run-off • Reducing vulnerability of the poor by diversifying food and income sources • Source of inspiration and learning
UPAF contribution to climate change mitigation, adaptation and cobenefits Co-benefits • Improved nutrition • Income generation and job creation • Social and community building
