||: In order to maintain or even to contribute to the improvement of the quality of life, of the environment and of health, it is necessary to apply the principles and strategies of durable development, but also to elaborate the ways and methods of stopping the degradation of the environment, the implementation of environmental policies and strategies in all the fields of the economic activity. In what concerns the urban and peri-urban area of the city of Arad, we notice two stages of development: the one prior to 1990 and the one after that timeline, these two being differentiated due to the economic evolution of the county. Prior to 1990, the economy of the county of Arad has been dominated by the chemical industry, the machine tools industry, the textile industry, the wood processing industry, and the food industry. Most of these establishments would also cause an intense pollution of the environment. After the 1990s and up to present, a great part of the industry of Arad has been redefined, given the emergence of activities with a low pollution potential that have been placed outside the city, at a distance of circa 2 – 2.5 km West, on the industrial platform. The impact of these industries on the environment is thus insignificant. A negative phenomenon which we have to notice, regarding the placing of the new industrial area outside the town, is the granting of space on agrarian fields with a great productivity potential. This aspect is worrisome, having no connection with the durable development, but all too often the city officials create such type of “compensations” out of the desire to develop the local economy. Thus, major unbalances may appear in what concerns the rational allocation of natural resources and they may have a significant and long-term impact on the environment.
