In conducting the scientific endeavor we started from the assumption that directing the efforts of local communities based on the principles of sustainable development, the degree of socio-economic development of the Tecuci Plain will be improved in a time span of 25-30 years. The development of the plain is below its potential but it presents viable resources that can lead to the shaping of sustainable development strategies applicable at territorial level. The various works consulted point out that the sustainable development of an area requires a complex precede that provides the analysis of all factors which can influence human settlements’ development of perspective. In this sense it entails identifying the natural conditions of the Tecuci Plain and how they are reflected by the socio-economic development of human settlements, knowing that this space is identified at regional and national level as an important agricultural center that utilizes rationally the land. The quintessence that can accelerate the sustainable development of the territory is given by the accessibility to the local and regional context of the Tecuci Plain. Accessibility is also a prerequisite in establishing a network of centers polarizing localities that maintain functional interdependencies and diffusion of services across sectors. The knowledge of space and disorders diagnosing are absolutely necessary for integrating development policies to implement the phenomenon of territorial, social and economic cohesion. Rural settlements of the Tecuci Plain radiate around the only urban center, the city of Tecuci, center that tries to regain its identity and its importance by channeling efforts to promote agricultural products in the region, given that the secondary and tertiary sectors fail to gain ground in front of the basic occupation of 60% of the administrative units that are part of the plain. The rural component from the Tecuci Plain is actually a whole scale (system) “built” on a macro scale with three elements (subsystems): the physical subsystem (environmental and natural conditions), the social subsystem (rural population and habitat rural) and economical subsystem (external physical environment transformed by the rural population).
