Ditches and canals are omitted from global budgets of inland water emissions, despite research showing them to be emitters greenhouse gases (GHGs). Here, we synthesize data across climate zones land use types show, for the first time, that ditches emit notable amounts carbon dioxide (CO2) nitrous oxide (N2O). had higher per-area emissions CO2 N2O than ponds, lakes, reservoirs, likely due high nutrient inputs. Preliminary upscaling showed inclusion would increase by 0.6%-1% 3%-9%. Trophic...
Agricultural ditches emit disproportionate amounts of nitrous oxide (N
Agricultural ditches are pervasive in agricultural areas and potential greenhouse gas (GHG) hotspots, since they directly receive abundant nutrients from neighboring farmlands. However, few studies measure GHG concentrations or fluxes this particular waterbody, likely resulting underestimations of emissions regions. Here we conducted a one-year field study to investigate the typical ditch systems, which include main (MD), branch (BD), collector (CD), (FD), an irrigation district located...
