Roads and particularly those adapted to the automobile, constitute an essential element in the shaping of landscapes. In Europe they were built within historic corridors and incorporate both heritage assets of the period of construction of the road as well as valuable pre-existent assets. Heritage studies have provided partial valuation that tends to focus on the scenic aspect of roads, the technical valuation of original sections or the architectures built to offer services to the infrastructure. The article aims to define a method to enable the integral analysis of the heritage complexity of roads. This research focuses on the Spanish N-340 corridor, a historic connection between Europe and Africa that was very much transformed over the 20th century as a result of tourist occupation. The research also develops an online heritage database that allows the interrelation of the different assets, maximum accessibility and continuous updating. Keywords: heritage visualization, historic road corridor heritage, information and communication technology.

Effective river management requires integration of biophysical and human dimensions of the ecosystem, which in turn involves the development of new forms of decision-making processes and institutional frameworks. In New South Wales, institutional changes to river management have been formalized in the Water Management Act 2000. This paper presents the findings of a case study that investigated decision-making processes in the establishment of environmental flow regimes for the Lachlan River in western New South Wales. The study was based on document analysis, observation and interviews with members and support staff of a stakeholder-based river management committee. The findings of the study highlight social capital, adaptive management and consensus decision making as key components in establishing environmental flow regimes as part of a participatory approach to river management.

Following its rise to international prominence, sustainability has become an official principle or goal in many countries. Due to contextual differences, countries have followed different paths in the pursuit of sustainability. Approachescan be classified into three categories: green planning; institutional reform; and social mobilization. None of these courses on its own is likely to achieve sustainability. Yet, countries often appear to develop a path dominated by one of these approaches. This paper focuses on Australia, sketches the extent to which green planning, institutional reform and social mobilization have been playing a role in the pursuit of sustainability, and illustrates the difficulties of developing a pathway that combines these approaches.
