Fig. 2: Map of food production and associated impacts.
From: Leveraging circular nutrients to improve the sustainability of peri-urban agriculture
Map for normalized food production (a) for current peri-UA areas in the Metropolitan area of Barcelona (AMB), Spain. Further this map is overlayed with the maps for normalized impacts of Marine eutrophication (ME) (b), and for climate change (GWP100) in each scenarios except compost (c) and climate change (GWP100) for compost current (d), BAU (e) and 2-degree scenario (f). Food yields and impacts per plot are normalized to the maximum value per parameter. Colour pattern consists of nine-colours organized in a grid from low to high for yield on y-axis and impact in x-axis. Data for food production and impacts is divided into three classes using equal intervals.
