Abstract
Human activity is deeply funded on the availability of natural resources. They
are mostly provided for free by the environment and often neglected by
traditional accounting systems since it is difficult to express their contribution or
their physical weight in monetary unit, more familiar to most people.
Inventorying all the flows of energy and matter that feed a territorial system and
giving them a non-market value plays an important role in the field of natural
resources management, sustainability policies and territorial planning. A
physical based environmental accounting method is implemented in order to
evaluate all the resources used within the area on a common basis, beyond the
economic scheme, which allows a deeper knowledge of the system. The tool is
emergy evaluation, a thermodynamics-based approach, introduced by Howard T.
Odum during the 1980s. The use of emergy enables one to calculate some
sustainability indicators (such as Environmental Loading Ratio, Emergy per
Person, Empower Density, Emergy Investment Ratio), and is able to give a
systemic and holistic picture of the system from an environmental point of view.
The paper presents a sustainability assessment at regional level by monitoring
the use of resources and the results of the analysis could be used to design
different development models and scenarios with several implications for the
administrative activity. The results orient environmental management solutions
for territorial planning and sustainable policies.
Keywords: territorial planning, resource management, emergy evaluation;
