- Evolution of the production systems of the endangered catle breed Mirandesa: threats and alternatives for family-farm systemsPublication . Sousa, Fernando Ruivo de; Aguiar, Carlos; Aveiro, DinaFamily-farm systems are largely dominant in the rural communities of northeastern Portugal. These systems can be organized based on the interrelations and the diversity of its characteris5cs such as farmer's age, farm dimension, external incomes, productive orientation, or livestock type and number (1). A significant number of the regional family-farm systems raise Mirandesa cows, a local cattle breed classified as endangered in 1994. Since 1995 the Mirandesa veal enjoys a Protected Designa5on of Origin (PDO). The carcasses of weaning calves, that aren’t PDO, are currently paid 4 €/kg. The PDO producers receive 5,25€/Kg, a 31% higher premium price. Since 1998, a producers group guarantees the sale of all production. In the last decade, the national inflation average was 2.45%; the group achieved a gross margin on the sale price, on average, 1% above infla5on. However, despite the commercial success of the PDO, the Mirandesa cow and the farmers numbers continues to decline.
- Mountain farming systems efficiency and sustainabilityPublication . Pires, Jaime; Arrobas, Margarida; Aguiar, Carlos; Ferreira, Isabel C.F.R.; Azevedo, JoãoThe efficient use of resources and farming inputs is considered a key factor for sustainability in agriculture The ecological limitations of the productivity in mountains make the study of efficiency in agricultural systems in these areas even more crucial Based on these assumptions, we present in this study the preliminary results of efficiency analysis of farming systems, in mountain regions of Portugal
