Seven statistical regions were adopted in Hungary by the decision of the Parliament in 1998.
The Region of West Transdanubia includes the counties Győr-Moson-Sopron, Vas and Zala. The extension of the region is lengthy in the direction North-South.
The region borders on four countries: on Austria in the west, on Slovenia and Croatia in the southwest and on Slovakia in the north. The region is neighbouring with the Region of Central Transdanubia in the east, while with the South Transdanubian Region in the south.
The territory of the region is 11 183 km2 that includes 12 % of the territory of Hungary. County Győr-Moson-Sopron occupies 36 % of this terrain, while County Vas 30 % and County Zala 34 %.
The geography of West Transdanubia is extremely various. Three big areas extend on its territory: the Little Plain, the Foothills of the Alps and the major part of the Transdanubian Hills completed with the northern and western fringes of the Transdanubian Mountains. The region has diversified surfaces and is rich in streams as well as in natural and artificial still waters. There are numerous natural areas under national protection in the region (National Park Fertő-Hanság, National Park Őrség). Considering natural resources, the region is rich in thermal and mineral water which may be found equally in all part of it.
The West Transdanubian Region is rich in natural resources which should be preserved because of economic and environmental interests. Their careful utilisation is a great opportunity and task of sustainable development.
In spite of the establishment of business parks, the region is not endangered by serious environmental problems. After the democratic transformation, the production of many industrial branches out-of-date that polluted the environment seriously (e.g. textile industry, engineering industry) was stopped, decreased or was transformed. The pollution of agriculture decreased as well, since the price gap between agricultural and industrial products widened. Therefore, natural resources are relative unharmed. The conservation of the high biodiversity is important in the aspect of environment, economy (tourism) as well as society (quality of life).
