The existence of spatial strategic interaction between neighbouring local governments is often referred in literature and identified in empirical applications for several countries. The spatial interaction in local government expenditure finds support on three theoretical explanations: spillover...

Soil erosion is serious economic and environmental concern. Assessing soil erosion risk in the Alqueva dam watershed is urgently needed to conserve soil and water resources and prevent the accelerated dam siltation, taking into account the possible land-use changes, due to tourism development,...

Erosion has been a distress on anthropogenic activity since antiquity. The changes in spatial properties in coastal changes in wetland systems have had a constantly mutating morphology, often obliging economic activity to readapt itself to the geomorphological conditions. This has had a profound...

Through a socioecological approach we intend to apply to territorial systems a similar interpretation to those currently used in ecosystem’s management. Therefore, we will try to consider a territorial unit as a human ecosystem, being an interaction of natural and social dynamics. The...

The present paper present some of the adverse ecological parameters studied for the assessment of reclamation of the lignite spoil heaps of Ptolemaida in North Greece. Natural revegetation was the first step before reclamation began and it was studied. Natural vegetation of lignite spoil heaps...

New Economic Geography (NEG), a new branch of Spatial Economics that was developed at the beginning of the 90s, supports that “peripheral” European Union’s economies (like Portugal, Greece, Ireland or even Spain) are predestined to diverge from the developed European “centers” like...

Theoretical analysis of the relevance of the concept of path dependence for regional analysis has made progress. This has occurred on the spatial process (or regional paradigm)dimension of spatial evolution Progress has also occurred after further reflections on the roles of ‘conventions’ in...

Coastal regions involve a set of interactions between tourists and residents, which implies that management and marketing strategies should take into account both stakeholders. Indeed, one of the greatest challenges of destination management organizations is to understand that they serve not...

The Deepwater Horizon oil spill dumped almost 5 million barrels of oil into the Gulf of Mexico over a three month period in 2010. This event had a significant economic impact (which compounded the recession effect) on the surrounding regions particularly those with a large marine industry...

The problem of developing a sustained presence in the ocean is discussed, with special emphasis on networked vehicle systems. This is done in light of the recent technological developments and trends. First, we discuss illustrative examples of developments from the Laboratório de Sistemas e...
