Environmental management of forested areas • Forestry policy is directed towards nature conservation and environmental protection • Focus on socio-economic and cultural benefits and not on production • Ecology and biodiversity • 2004: National Forest Program of Hungary The main objective of the National Forest Program is to ensure long term sustainability and to satisfy the demands of consumption, environmental protection, recreation taking socio-economic and cultural aspects into account. Strategic objectives • Protection and support of natural processes • Conservation and rehabilitation of quasi natural forests • Protection of protected and rare species • Landscape protection • Maintenance of forested area Territorial data • Forest area: 1.974 million ha • Area covered by trees: 1.843 million ha • Percentage of forested area: 19.8% • 387 million ha are protected (20%) Changes of the forested area Forested areas in Hungary (2006) Afforestation between 1920 and 2005 Mountains of Hungary Hungary has several moderately high ranges of mountains. They can be classified to four geographic regions, from west to east: Alpokalja, Transdanubian Mountains, Mecsek and Northern Mountains. Alpokalja (literally the foothills of the Alps) is located along the Austrian border. The Transdanubian Mountains stretch from the west part of Lake Balaton to the Danube Bend near Budapest, where it meets the Northern Mountains. Mecsek is in the southern part of Transdanubia.

Ensuring flood security in an environment friendly way • increasing flood risk because of climate change • opening new areas on the floodplains for flood water storage • flood strategy should include also the headwater catchment and not only the floodplains • flood strategy has to be complex taking not only the floods but all kinds of human activities • international co-operation – headwater catchments • adequatic strategy includes 3 steps: • keeping rainfall water on the site • storing surplus locally • only surplus not stored locally may enter the stream 2. Water supply of settlements • aquatic ecosystems should be protected • sewage treatment – canalisation is not everywhere, karstic wat ers are very sensitive • supply of healthy drinking water • conserving our water basis, i.e. subsurface waters 90% of drinking water comes from subsurface waters 3. The problem of inland inundations on lowlands 4. The problem of groundwater subsidence on the Danube-Tisza Interfluve • increasing groundwater exploitation • afforestation • intensive agriculture 5. The effect of thermal tourism on the state of thermal waters • over exploitation • the problem of used thermal waters .
