In research literature, a lack of common understanding of “development” concept is identified. The meaning of “development” changed during the last decades from simple economic growth, embracing social and environmental concerns. 

The aim of this paper is  to highlight the integrated development theory, through the synthesis of three interdisciplinary research projects, applied to the area of Konitsa, within the postgraduate program "Environment and Development of Mountainous Areas" of the NTUA. The results provided for each methodological step and the integrated approach of the development scenarios can be used as an important tool, contributing to the design, development and support of relevant policies.
