Potentially sewage sludge could be utilised on 3.085.100 ha in the country, but in reality the ratio where sewage sludge usage is permitted by the authority is only 1.5%. 300000 250000 200000 >■ 150000 *o ~ 100000 50000 0 2 005 2 015 2 025 2 035 year Figure 22. Amount of produced sewage sludge in Hungary (tdJy) (Source: OVF 2014) In order to promote agricultural utilisation of sewage sludge as an excellent source of nutrients, current tender schemes, subsidies and the legal background need to be revised. Shaping attitude “A basic aim of environmental education is to succeed in making individuals and communities understand the complex nature of the natural and the built environments resulting from the interaction of their biological, physical, social, economic and cultural aspects, and acquire the knowledge, values, attitudes, and practical skills to participate in a responsible and effective way in anticipating and solving environmental problems, and the management of the quality of the environment. ” (Tbilisi Declaration 1977). We have to strengthen the approach in environmental communication and environmental education that water is a valuable resource. From nursery school through primary and secondary schools, family life can be a stage for environmental education and attitude shaping the sustainable management of water resources. Sustainable development requires an approach that is able to handle challenges of the world looking at the whole system and able to reach and preserve the fine equilibrium among economy, society and environment.
