Economical and environmental trade-offs of traditional Mediterranean dry farmin...

Rosado, Maria Maurícia; Fragoso, Rui; Marques, Carlos

This paper aims assessing the economic and environmental trade-offs of traditional Mediterranean dry farming systems in the Alentejo region, southern Portugal. An environmental analysis using environmental indicators, such as the nitrogen balance, energy input, greenhouse gas emissions, acidification, eutrophication impacts, as well as an aggregated eco-indicator were developed. For assessing economic returns o...

Sustainability of crop and livestock dominant dryland system of Alentejo region...

Rosado, Maria Maurícia; Marques, Carlos; Fragoso, Rui

This paper presents a case study with two traditional Mediterranean-type farming systems: grazing dominant and cropping dominant, of the Alentejo region of Portugal. Farming systems traditional of the Alentejo area and of the Mediterranean region are compared in terms of economic returns, environmental impacts and trade-offs. Methodological aspects for environmental impacts evaluation during cradle-to-gate of a...


CLUSTERING OF TERRITORIAL AREAS: A MULTI-CRITERIA DISTRICTING PROBLEM

Fragoso, Rui; Rego, Conceição; Bushenkov, Vladimir

Endogenous resources, economic profile and socio-economic issues are the criteria that define the development level and the identity features of a territorial unit. The territorial units that organize the country, in political and administrative terms – parishes and counties –, have a hierarquical structure, which initially reflected the organization of productive activities as well as the tradition State organ...


ESTIMATION OF COST ALLOCATION COEFFICIENTS AT THE FARM LEVEL USING AN ENTROPY A...

Fragoso, Rui Manuel de Sousa; Carvalho, Maria Leonor da Silva; Shikida, Pery Francisco Assis; Rocha Jr, Weimar Freire

This paper aims to estimate the farm cost allocation coefficients from whole farm input costs. An entropy approach was developed under a Tobit formulation and was applied to a sample of farms from the 2004 FADN data base for Alentejo region, Southern Portugal. A Generalized Maximum Entropy model and Cross Generalized Entropy model were developed to the sample conditions and were tested. Model results were asses...


UM MODELO DE DESAGREGAÇÃO DE ENCARGOS DE PRODUÇÃO VARIÁVEIS DA BASE RICA POR AC...

Rosário, Maria do Socorro; Fragoso, Rui Manuel de Sousa; Carvalho, Maria Leonor da Silva

A base de dados da RICA contém informação relativa ao total dos custos por tipo de factor não sendo, no entanto, desagregada por actividade. A obtenção dos custos variáveis por actividade é extremamente importante para a gestão da exploração e análise da política agrícola. O objectivo deste artigo é estimar os coeficientes de afectação dos custos às actividades agrícolas, a partir de informação incompleta. Um m...

Dos Santos, Maria José Palma Lampreia; Henriques, Pedro Damião de Sousa; Fragoso, Rui Manuel de Sousa; Carvalho, Maria Leonor da Silva

O principal objectivo deste artigo é conhecer as atitudes dos agricultores face à produção agrícola, ao apoio político e ao projecto de rega de Alqueva numa micro-região mediterrânica do Sul de Portugal, no contexto da Política Agrícola Comum (PAC) de 2003 e do Health-Check. Simultaneamente, pretende-se conhecer as intenções comportamentais destes agricultores frente à inovação tecnológica e ao futuro regadio p...

Fragoso, Rui Manuel de Sousa; Carvalho, Maria Leonor da Silva; Henriques, Pedro Damião de Sousa

In this paper, the calibration and prediction capacity of a supply response positive mathematical programming model (PMP) for the Alentejo region are evaluated. The model is calibrated with prices and agricultural subsidies of the base year (2000), using the specification rules of the cost function standard, Paris standard, average cost and exogenous elasticities. Then, the model is utilised for prediction of c...


IMPACT OF THE 2003 CAP REFORM AND THE HEALTH-CHECK IN ALQUEVA IRRIGATED PROJECT

Dos Santos, Maria José Palma Lampreia; Fragoso, Rui Manuel Sousa; Henriques, Pedro Damião de Sousa; Carvalho, Maria Leonor da Silva

One of the major challenges of the Alqueva Irrigation project is to benefit with irrigation, 110 000 ha. of dryland area. This project has a huge potential because it is located on a traditional agricultural area and has agro-weather conditions favourable to the development of irrigation crops. However, there is some challenges that needed to be overcome, namely the recent developments of the Common Agricultura...


Avaliação e Impacte Ambiental e Económico de Medidas Agro-ambientais no Context...

Rosado, Maria Maurícia; Fragoso, Rui; Marques, Carlos

A consciencialização da necessidade de desenvolver sistemas agrícolas sustentáveis, de reduzir os impactes ambientais das práticas agrícolas e o compromisso da UE integrar as questões ambientais na política agrícola (PAC) traduziu-se na obrigatoriedade do cumprimento da ecocondicionalidade e na implementação de medidas agro-ambientais nos Estados-Membros. O principal objectivo deste artigo é avaliar ambiental ...
