THE ECOLOGICAL SUSTAINABILITY BASE FOR EXTERNALITY ASSESMENT

Through the monitoring activity, politicians, can evaluate the farmers payments for their externalities on the environment, the farmers can check their costs of agricultural practices and environmental investments and the advisors can orient their farmers to the practices more sound to the environment and less costly for their budget. In this review, a measuring method including environmental and financial indicators is introduced. The set of the environmental indicators used in this method is called Environmental Accounting Information System (EAIS). Some economical indicators are integrated with EAIS. This can be a good base for the evaluation of the externalities on the environment.As measuring method, it considers the Integrated Environmental Accounting Information System in the pedo-climatic conditions of the activity and plant to be considered. Indicators in the EAIS has to be chosen in relation to critical points presented by two different farm conditions that will compared between them. Critical points are the factors hamper the farm management or that can deteriorate the environment and natural resources. A good attention was paid on the methods used for assessment of the indicators in order they to be practical and easy to be adapted by the farmers. For the assessment of the indicators values EAIS need some data which mainly come from: farm economic-accounting system, interviews, farm maps, area public organizations, bibliographical sources, farm nutrient accounting systems, observation in the field and chemical analyses of the soil.
