Authors: Oliveira, Maria Leonor; Pacheco Coelho, Manuel Abstract: The main objective of this paper is to discuss if landscape can be associated with sustainable development at the conceptualization level and in its program of operation research. It starts with the analysis of the concept of sustainable development in an historical perspective that put attention to the way it was constructed, as the emergence of environmental threats was imposing a new reflection to decision makers. Then it analyses the fundamental issues that this conceptualization put to the three pillars of approach: economic, environmental and social, and the way they must reconcile. Finally the concept of landscape is introduced and its role in the support of sustainable development is discussed. The landscape as a concept that, both, incorporates a vision of the global system of interactions between natural and human aspects in the territory, and a practice of intervention on the area (aiming to develop the quality of living from a perspective of intergenerational equity) emerges as an integral element of sustainable development concerns.

It is based on a research oriented to three main goals: 1 - the description and explanation of the formation of economic values, beliefs, attitudes and behaviors, based on a questionnaire submitted to a national sample, stratified by regional areas; 2 - the identification of the existent linkages between these micro-sociological variables and regional and national economic performance (e.g. GDP, unemployment rates, inflation, investment, debt and wages); 3 - the exploration of the role of human and social capital as moderators between micro-sociological variables and a support for different types of economic values. In this paper we explore the third goal, offering a tentative typology of economic values’ support.

There are two fundamental traditions in the legislation on hunting property rights: the Romanic tradition and the Germanic one, with different consequences in terms of resources use and conservation. The Economic Theory of Common Resources has been applied to provide conclusions about the management and conservation of hunting resources. In this paper, we derive a model of hunting management, adapting the Gordon/Schaefer fisheries model. The conclusions of the model are confronted with Portuguese hunting regulation.

Their main objective is to study and guarantee the sustainability of pensions funds. The use of these models with this goal is a classical approach in the study of pensions funds.
