- Analysing the recent dynamics of agricultural sustainability in Portugal using a compromise programming approachPublication . Xavier, António; Costa Freitas, M. B.; Fragoso, Rui; Rosário, Maria do SocorroSociety recognises the importance of agriculture to supply goods, which are essential for human survival and well-being. Sustainable agriculture is an important goal since resources need to be preserved for future generations. The recent agricultural policy orientations towards environmental concerns have also had consequences for Portuguese agriculture. The information provided by the 2019 Agricultural Census offers an opportunity to analyse the recent dynamics and establish rankings of municipalities related to agricultural sustainability. Sustainability in agriculture can be studied using different types of indicators, but its quantification and aggregation into an index is still difficult. This paper proposes an approach based on compromise programming to analyse sustainability considering the dynamics between the 2009 and 2019 Agricultural Census. This approach has three main steps: in the first one, the indicators are selected and a HJ-Biplot and Cluster analysis are carried out to identify groups of municipalities and general dynamics; in the second step, the weights of indicators are defined, and a novel compromise programming model is implemented to define the rankings of sustainability for each year; finally, in the third step, the spatial dynamics of the sustainability rankings are analysed and classified into the clusters of municipalities previously created. The analysis was implemented using data from the 308 Portuguese municipalities for 12 individual indicators encompassing the several dimensions of sustainability. The results were promising since the approach allowed for the identification of the main dynamics and tendencies regarding sustainability.
- Land-use evolution and trends in portugal: an approach based on the standard outputPublication . Xavier, António; Rosário, Maria do Socorro; Fragoso, Rui; Carvalho. Maria Leonor da Silva; Ferreira da Silva da Costa Freitas, Maria de BelémSince Portugal acceded to the European Union, the measures introduced under the Common Agricultural Policy (CAP) have significantly influenced farmers’ behavior and their choices of agricultural activities, with different consequences on agricultural sustainability. This paper analyses changes in crop-based income following the CAP evolution in Portuguese agriculture from 1989 until 2023 and their consequences on agricultural sustainability. The analysis is based on the Standard Output (SO) for temporary and permanent crops. These data were sourced from the Agricultural Census, conducted every ten years, and the Farm Structure Surveys were held every three years. To examine the evolution of land use and establish relationships between variables, the study employed HJ-Biplot methodology and cluster analysis. Then, a comparative analysis with agricultural sustainability trends, using several social and environmental indicators, was carried out. Regarding temporary crops, the results reveal a decline in the total SO weight of cereals for grain, alongside an increase in vegetables and floriculture. For permanent crops, a decrease was observed in fresh fruits and citrus fruits, while nuts and subtropical fruits showed notable growth. Also, the positive evolution of several SOs was accompanied by improvements in agricultural sustainability on environmental and social indicators.
