Evaluation of Water Resources through Efficiency Index and Water Productivity in EU

Water presents one of the earth resources as a component of environmental change, demanding the research of water use. A nusmber of authors analyzed water use from different perspectives, in different regions, not including the water efficiency index and water productivity in the whole of the EU. The presented contribution is orientated to the evaluation of water resources through the development of efficiency and productivity indexes in EU member states. The research is made by a single analysis of the index in time development, followed by countries’ comparison according to the available data and software support, accessing the sustainability features in water supply that are the three-fold-goals of economic feasibility, social responsibility, and environmental integrity, linked to the purpose of the water use. The results of the contribution show the countries with a positive indexes trend, and countries with a negative indexes trend. Such results can be used for improving measurements to increase water productivity, as well as to make measurements to decrease water use.
