The economics of woodland eggs in the UK
Burgess, P.; Belot, V.; Buachie, E.; Cuartero de Frias, J.; Nedved, K.; Rodriguez Arquero, E.Presentation ; This paper will report on a current study on the economics of woodland eggs in the UK for the Woodland Trust, due to be completed in early May 2014. An increasing proportion of the eggs sold in the UK are obtained from “free-range†hens who can roam outdoors. In some situations the outdoor environment is a field of grass. However at least 150 producers in the UK have opted to plant tree...
Past, present, and future of agroforestry systems in Europe in agroforestry: th...
Mosquera-Losada, M.R.; Moreno, G.; Pardini, A.; McAdam, J.H.; Papanastasis, V.; Burgess, P.J.; Lamersdorf, M.; Castro, Marina; Liagre, F.Many traditional land-use systems in Europe involved agroforestry in the pre-industrial era, but, over the years, increased mechanization led to the development of increasingly specialized crop, animal and wood production systems. As a consequence, the area under agroforestry declined in many regions of Europe, and agroforestry systems became confined to situations where understorey primary production is restri...

Modelling environmental benefits of silvoarable agroforestry in Europe
Palma, J.H.N.; Graves, A.R.; Bunce, R.G.H.; Burgess, P.J.; Filippi, R.Increased adoption of silvoarable agroforestry (SAF) systems in Europe, by integrating trees and arable crops on the same land, could offer a range of environmental benefits compared with conventional agricultural systems. Soil erosion, nitrogen leaching, carbon sequestration and landscape biodiversity were chosen as indicators to assess a stratified random sample of 19 landscape test sites in the Mediterranean...
Methodological approach for the assessment of environmental effects of agrofore...
Palma, J.H.N.; Graves, A.R.; Burgess, P.J.; Keesman, K.J.; Keulen, H. vanSilvoarable agroforestry, the deliberate combined use of trees and arable crops on the same area of land, has been proposed in order to improve the environmental performance of agricultural systems in Europe. Based on existing models and algorithms, we developed a method to predict the environmental effects of SAF at a farm and landscape scale. The method is comprised of an assessment of soil erosion, nitrogen ...
Integrating environmental and economic performance to assess modern silvoarable...
Palma, J.H.N.; Graves, A.R.; Burgess, P.J.; van der Werf, W.; Herzog, F.Analysis ; The environmental and economic performance of silvoarable agroforestry in Europe is highly variable. Multi-criteria analysis, using the PROMETHEE outranking approach, was used to evaluate the integrated performance of silvoarable agroforestry on hypothetical farms in nineteen landscape test sites in Spain, France, and The Netherlands. The silvoarable scenarios allocated a proportion of the hypotheti...
Development and application of bio-economic modelling to compare silvoarable, a...
Palma, J.H.N.; Graves, A.R.; Burgess, P.J.; Herzog, F.; Moreno, G.; Bertomeu, M.; Dupraz, C.Silvoarable agroforestry could promote use of trees on farms in Europe, but its likely effect on production, farm profitability, and environmental services is poorly understood. Hence, from 2001 to 2005, the Silvoarable Agroforestry for Europe project developed a systematic process to evaluate the biophysical and economic performance of arable, forestry, and silvoarable systems in Spain, France, and The Netherl...
