Autor: Peter Higgins, Elizabeth Bomberg, David S. Reay, Stephen D. Porter
Publikováno v: Porter, S, Reay, D, Higgins, P & Bomberg, E 2016, ' A half-century of production-phase greenhouse gas emissions from food loss & waste in the global food supply chain ', Science of the Total Environment . https://doi.org/10.1016/j.scitotenv.2016.07.041
Research on loss & waste of food meant for human consumption (FLW) and its environmental impact typically focuses on a single or small number of commodities in a specific location and point in time. However, it is unclear how trends in global FLW and

Avoidable food losses and associated production-phase greenhouse gas emissions arising from application of cosmetic standards to fresh fruit and vegetables in Europe and the UK
Autor: Stephen D. Porter, Peter Higgins, Elizabeth Bomberg, David S. Reay
Publikováno v: Porter, S, Reay, D, Bomberg, E & Higgins, P 2018, ' Avoidable food losses and associated production-phase greenhouse gas emissions arising from application of cosmetic standards to fresh fruit and vegetables in Europe and the UK ', Journal of Cleaner Production . https://doi.org/10.1016/j.jclepro.2018.08.079
The use of aesthetics for classifying and accepting fresh food for sale and consumption is built into food quality standards and regulations of the European Union. The food distribution sector in Europe and the UK is oligopolistic in nature; a small

Production-phase greenhouse gas emissions arising from deliberate withdrawal and destruction of fresh fruit and vegetables under the EU's Common Agricultural Policy
Autor: Elizabeth Bomberg, David S. Reay, Stephen D. Porter, Peter Higgins
Publikováno v: Porter, S, Reay, D, Bomberg, E & Higgins, P 2018, ' Production-phase greenhouse gas emissions arising from deliberate withdrawal and destruction of fresh fruit and vegetables under the EU’s Common Agricultural Policy ', Science of the Total Environment . https://doi.org/10.1016/j.scitotenv.2018.03.089
Since 1962 the Common Agriculture Policy (CAP) of the European Union (EU) has enabled payment of subsidy to some food producers for withdrawal of specific commodities – including fresh fruit and vegetables (FFV) – where market prices have fallen

Publikováno v: Freshwater Biology. 53:1036-1054
SUMMARY 1. Algal-community metrics were calculated for periphyton samples collected from 976 streams and rivers by the U.S. Geological Survey’s National Water-Quality Assessment (NAWQA) Programme during 1993–2001 to evaluate national and regional

Influence of fipronil compounds and rice-cultivation land-use intensity on macroinvertebrate communities in streams of southwestern Louisiana, USA
Autor: Scott V. Mize, Dennis K. Demcheck, Stephen D. Porter
Publikováno v: Environmental Pollution. 152:491-503
Laboratory tests of fipronil and its degradation products have revealed acute lethal toxicity at very low concentrations (LC50) of0.5 microg/L to selected aquatic macroinvertebrates. In streams draining basins with intensive rice cultivation in south

Addressing food supply chain and consumption inefficiencies:potential for climate change mitigation
Autor: Stephen D. Porter, David S. Reay
Publikováno v: Porter, S & Reay, D S 2015, ' Addressing food supply chain and consumption inefficiencies : potential for climate change mitigation ', Regional Environmental Change . https://doi.org/10.1007/s10113-015-0783-4
Globally, more than 30 % of all food that is produced is ultimately lost and/or wasted through inefficiencies in the food supply chain. In the developed world this wastage is centred on the last stage in the supply chain; the end-consumer throwing aw

HERBICIDES AND TRANSFORMATION PRODUCTS IN SURFACE WATERS OF THE MIDWESTERN UNITED STATES
Autor: Earl M. Thurman, Stephen J. Kalkhoff, Stephen D. Porter, William A. Battaglin
Publikováno v: Journal of the American Water Resources Association. 39:743-756
Most herbicides applied to crops are adsorbed by plants or transformed (degraded) in the soil, but small fractions are lost from fields and either move to streams in overland runoff, near surface flow, or subsurface drains, or they infiltrate slowly
