Reducing nitrogen pollution across the food chain requires use of clear and comprehensive indicators to track manage losses. The challenge is derive an easy-to-use robust efficiency (NUE) indicator for entire systems help support policy development, monitor progress inform consumers. Based on a comparison four approaches NUE (life cycle analysis, footprint, budget, environmental impact assessment), we propose broader application at national scale: whole (NUEFC), which defined as ratio...
Humans increase the amount of reactive nitrogen (all N species except N2) in environment through a number processes, primarily food and energy production. Once environment, excess may cause host various environmental problems. Understanding controlling individual footprints is important for preserving human health. In this paper we present per capita footprint Japan. We considered effect international trade feed, impact dietary preferences among different consumer age groups. Our results...
Tidal floods (i.e., “nuisance” flooding) are occurring more often during seasonal high tides or minor wind events, and the frequency is expected to increase dramatically in coming decades. During these flood coastal communities’ roads impassable difficult pass, thus impacting routine transport needs. This study identifies vulnerable quantifies risk from nuisance flooding Eastern United States by combining public road information Federal Highway Administration’s Performance Monitoring System...
People have increased the amount of reactive nitrogen (Nr) in environment as a result food production methods and consumption choices. However, connection between dietary choices environmental impacts over time has not yet been studied China. Here we combine footprint tool, N-Calculator, with chain model, NUFER (NUtrient flows Food chains, Environment Resources use), to analyze N We use model provide detailed estimation amounts forms Nr released during production, which is then used...
The relative importance of environmental factors and host in explaining variation prevalence intensity flea parasitism small mammal communities is poorly established. We examined these relationships an East African savanna landscape, considering multiple levels: across individuals within a local population, populations species, species landscape. sampled fleas from 2,672 mammals 27 species. This included total 8,283 fleas, with 5 genera 12 identified. Across individual hosts site, both...
Abstract The nitrogen footprint tool (NFT) provides a novel way for communities to understand the environmental impacts of their collective activities and consumption. Reactive (Nr; all N species except 2 ) is created by Haber–Bosch process food production as by-product fossil fuel combustion two natural processes, biological fixation lightning. While it vital input production, too much Nr has negative effect on environment. Calculating amount released environment result an entity’s resource...
