Comparative studies on energy efficiency and GHG emissions between conventional...
Balafoutis, A; Baptista, F; Briassoulis, D; Silva, LL; Panagakis, P; Murcho, DNowadays, traditional farming based on achieving high yields using high inputs, shifts gradu-ally towards maximum possible crop yield using minimal inputs in an optimized way or to-wards organic farming. This is usually accomplishing by low yield of high quality products without using conventional agrochemicals (i.e. fertilizers, pesticides). In general, this last ap-proach leads to lower energy consumption per...
Energy efficiency in agriculture
Baptista, Fatima; Silva, LL; de Visser, C; Gołaszewski, J; Meyer-Aurich, A; Briassoulis, D; Mikkola, H; Murcho, DOne of the EU headline target indicators for Europe is “20% increase in energy efficiency” by 2020. It is anticipated that in the following decades energy use will increase significantly and will have a widespread impact on the economy, including the agricultural sector. Energy use reduction can be achieved by reduced energy input. Improved energy efficiency, however, is only achieved, if energy input per unit ...
Energia, ambiente, economia e olival no Alentejo. Estudo preliminar
Baptista, F; Murcho, D; Silva, LL; Silva, JR; Marques, C; Dias, A; Peça, JO; Sousa, APrevê-se que o consumo de energia na agricultura irá aumentar significativamente nos próximos anos com a intensificação dos sistemas de produção. As melhorias na eficiência energética dos sistemas de produção estão relacionadas com a redução do uso de energia para um determinado serviço ou nível de actividade, ou a um aumento de produtividade para a mesma energia consumida. Os sistemas de produção agrícola estã...
Agricultura e Eficiência Energética - Projecto AGREE. Caso de Estudo: Produção ...
Baptista, F; Silva, LL; Murcho, D; Louro, M; Marques, CUm dos objectivos da União Europeia para 2020 é o aumento em 20% na eficiência energética. De facto, espera-se um aumento significativo no consumo de energia nas próximas décadas, com elevado impacto na economia, incluindo o sector agrícola. A poupança de energia pode conseguir-se directamente através da redução do consumo de energia. No entanto, a melhoria da eficiência energética apenas se consegue se os cons...
Agriculture and energy efficiency in portuguese agriculture and trade-offs with...
Baptista, F; Marques, C; Silva, LL; Murcho, D; Silva, JR; Peça, JOThis paper aims to present and discuss an economic and environmental analysis based on case studies for selected Portuguese agriculture production systems which show potentials and constraints of energy efficiency measures in agriculture with respect to the specific environment of Portugal. Results are the Portuguese part of one work package of AGREE (AGRiculture and Energy Efficiency) an European project. It i...
Less or more intensive crop arable systems of Alentejo region of Portugal: What...
Marques, C; Baptista, F; Silva, LL; Murcho, D; Rosado, M; Silva, JR; Peça, JOCompetitiveness of traditional arable crop system of Alentejo region of Portugal has been questioned for long. Discussion and research on the sustainability of the system has evolved on two contrasted alternative options for production technologies to traditional system. On the one hand reduced and no tillage systems aim to more extensive technical operations reducing costs and maintaining production, or even t...
Aktualny stan efektywnosci energetycznej w rolnictwie Unii Europejskiej (The cu...
Golaszewski, J; de Visser, C; Brodzinski, Z; Myhan, R; Olba-Ziety, E; Stolarski, M; Buisonjé, F; Ellen, H; Stanghellini, C; van der Voort, MEnergy efficiency is the goal of efforts to reduce the amount of energy required to provide products and services. The general term "energy efficiency", when applied to agriculture,reflects changes in technology, governmental and EC policies – including the Common Agricultural Policy, climate change on a broad scale and local weather patterns, and farming management practices. There is not a single measure to d...
Otoczenie zewnetrzne efektywnosci energetycznej w rolnictwie – studium przypadk...
Golaszewski, J; de Visser, C; Lutsyuk, C; Stolarski, M; Brodzinski, Z; Olba-Ziety, E; Myhan, R; Mikkola, H; Ahokas, J; Jokiniemi, T; Rajaniemi, MUntil recently energy efficiency in agriculture has received little attention. Nevertheless, energy consumption in agriculture is considerable, especially when indirect energy use is taken into account. AGREE has the objective of showing the potential of short term energy efficiency gains and the promise of a long term potential. Environmental effects of savings on direct and indirect energy use in agriculture ...
Dzialania energooszczedne w rolnictwie (Energy saving measures in agriculture)
Golaszewski, J; de Visser, C; Stolarski, M; Brodzinski, Z; Olba-Ziety, E; Myhan, R; Mikkola, H; Ahokas, J; Jokiniemi, T; Rajaniemi, M; Meyer-Aurich, AThe reduction of energy inputs in agricultural production is a process of practical implementation of a set of energy saving (ES) measures associated with a given type of production, farm infrastructure and managerial or organizational activities. In six national reports from Finland, Germany, Greece, the Netherlands, Poland and Portugal for 13 subsectors of agriculture, 481 ES measures in total were identified...

Meyer-Aurich, A; Jubaer, H; Scholz, L; Ziegler, T; Daalgard, T; Yli-Kojola, H; Esala, J; Mikkola, H; Rajaniemi, M; Jokiniemi, T; Ahokas, JThis text is the result of the collaboration of the partners of the AGREE work-package “Economic and environmental analysis”, which is based on case study analyses of the partners in seven countries of the EU. The case studies show economic and environmental trade-offs in the different regions in the EU, for which each partner is responsible. Nevertheless prior to the reporting of the case studies an intensive ...
