Land-use patterns in Austria change from Alpine to non-Alpine regions.[1] Approximately one-tenth of Austria is barren or unproductive, that is, extremely Alpine or above the tree line.[1] Just over 40% of Austria is covered by forests, the majority of which is in Alpine regions.[1] Less than one-fifth of Austria is arable and suitable for conventional agriculture.[1] The percentage of arable land in Austria increases in the East as the country becomes less alpine.[1] More than one-fifth of Austria is pasture and meadow located at varying altitudes.[1] Almost half of this grassland consists of high Alpine pastures.[1]

Historically, high Alpine pastures have been used during the summer for grazing dairy cattle, thus making space available at lower altitudes for cultivating and harvesting fodder for winter.[1] Many of the high pastures are at altitudes of more than 1,000 m.[1]

Although agriculture in mountainous areas was at one time economically viable, in recent decades it has survived only with the help of extensive subsidies.[1]

The Alps make many areas of Austria uninhabitable.[1] Austria's so-called areas of permanent settlement – regions that are cultivated, continuously inhabited, and used for transportation, but do not include forests, Alpine pastures, or barren land – cover only 40% or 35,000 km² of the country.[1] The great majority of the area of permanent settlement is in the Danube valley and the lowlands or hilly regions north, east, and south of the Alps, where approximately two-thirds of the population lives.[1]

In the country's predominantly Alpine provinces, most of the population live in river valleys: Bregenz on the shores of Lake Constance in Vorarlberg; Innsbruck on the river Inn in Tyrol; Salzburg on the river Salzach in Salzburg; and Klagenfurt on the Wörthersee lake in Carinthia.[1] The higher the Alps are, the less inhabitable they become in terms of soil, microclimate, and vegetation.[1] Conversely, the lower and broader the Alpine valleys are, the more densely populated they become.[1]

Tyrol illustrates most clearly the relationship between Alpine geography and habitation.[1] As the most mountainous province (less than 3% of the land is arable), it is the most sparsely inhabited, with an area of permanent settlement of only 15%.[1]

Because of the Alps, the country as a whole is one of the least densely populated states of Western and Central Europe.[1] With ninety-three inhabitants per square kilometre, Austria has a population density similar to that of the former Yugoslavia.[1]

Austria's national borders and geography have corresponded very little.[1] Since the fall of the Western Roman Empire, the Alps and the Danube have not served to mark political boundaries.[1] Even within Austria, provincial borders were only occasionally set by the ranges and ridges of the Alps.[1]

Although the Alps did not mark political boundaries, they often separated groups of people from one another.[1] Because in the past the Alps were impassable, inhabitants isolated in valleys or networks of valleys developed distinct regional subcultures.[1] Consequently, the inhabitants of one valley frequently maintained dialects, native or traditional dress, architectural styles, and folklore that substantially differed from those of the next valley.[1] Differences were great enough that the origins of outsiders could easily be identified.[1] However, mass media, mobility, prosperity, and tourism have eroded the distinctness of Alpine regional subcultures to a great extent by reducing the isolation that gave them their particular character.[1]

Despite the Alps, Austria has historically been a land of transit.[1] The Danube valley, for centuries Central Europe's aquatic link to the Balkan Peninsula and the "Orient" in the broadest sense of the word, has always been an avenue of east–west transit.[1] However, Europe's division into two opposing economic and military blocs after World War II diminished Austria's importance as a place of transit.[1] Since the opening of Eastern Europe in 1989, the country has begun to re-assume its historical role.[1] By the early 1990s, it had already experienced a substantial increase in the number of people and vehicles crossing its eastern frontiers.[1]

Within the Alps, four passes and the roads that run through them are of particular importance for north–south transit.[1] The Semmering Pass on the provincial border of Lower Austria and Styria connects the Vienna Basin with the Mürz and Mur valleys, thus providing northeast–southwest access to Styria and Slovenia, and, via Carinthia, to Italy.[1]

The Pyrhn Pass between the provinces of Upper Austria and Styria and the Tauern Pass between the High Tauern range and the Lower Tauern range of the Central Alps in Salzburg, provide access to the Mur Valley in Styria and the Drau Valley in Carinthia, respectively.[1] The highways that run through these passes are important northwest–southeast lines of communication through the Alps.[1] The Pyrhn highway has been nicknamed the Fremdarbeiterweg ("foreign workers' route") because millions of Gastarbeiter ("guest workers") in Germany use it to return to their homes in the Balkans and Turkey for vacation.[1] Many Germans and northern Europeans also use it in the summer months to reach the Adriatic coast.[1] After the outbreak of hostilities in Yugoslavia in the summer of 1991, however, a substantial amount of this traffic was re-routed through the Danube Valley and Hungary.[1]

The most important pass in the Austrian Alps is the Brenner Pass, located on the Austrian-Italian border in Tyrol.[1] At 1,370 m, it is one of the lowest Alpine passes.[1] The route up the Inn valley and over the Brenner Pass has been historically an important and convenient route of north–south transit between Germany and Italy, and provides the most direct route between Europe's two most highly industrialized regions: Germany and northern Italy.[1]

Köppen climate classification types of Austria

Heralding the oncoming winter, snow dusts the peaks of the Alps on December 11, 2004. North of the Alps, clouds cover France, Switzerland, Liechtenstein, Austria, and Slovakia. South of the Alps, clear skies dominate most of the image, leaving the Po River Valley and peninsular Italy showing clearly. To the southwest, the Ligurian and Mediterranean Seas are an almost uniform deep blue color; to the southeast, the Adriatic Sea features swirls of blue-green microscopic sea organisms (likely phytoplankton and algae), as well as some green-tan sediment from rivers emptying into the sea.

The Alps serve as a watershed for Europe's three major kinds of weather systems that influence Austrian weather.[1] The Atlantic maritime climate from the northwest is characterized by low-pressure fronts, mild air from the Gulf Stream, and precipitation.[1] It has the greatest influence on the northern slopes of the Alps, the Northern Alpine Foreland, and the Danube valley.[1] The continental climate is characterized by low pressure fronts with precipitation in summer and high pressure systems with cold and dry air in winter.[1] It affects mainly eastern Austria.[1] Mediterranean high-pressure systems from the south are characterized by few clouds and warm air, and they influence the weather of the southern slopes of the Alps and that of the Southeastern Alpine Foreland, making them the most temperate part of Austria.[1]

One peculiarity of the Mediterranean weather systems is the föhn wind, a warm air mass that originates in the African Sahara and moves north rapidly, periodically raising temperatures up to 10 °C (18 °F) in a short period of time.[1] Many people respond to this rapid weather change with headaches, irritability, and circulatory problems.[1] During the winter, the rapid warming that accompanies a föhn can thaw the snow cover in the Alps to such an extent that avalanches occur.[1]

Given the importance of Alpine skiing for the Austrian tourist industry, December is the month during which the weather is watched with the greatest anticipation.[1] As a rule, Atlantic maritime weather systems bring snow, and continental weather systems help keep it.[1] However, a predominance of cold, dry continental systems or warm Mediterranean ones inevitably postpone the beginning of the ski season.[1] In the summer, Mediterranean high-pressure systems bring warm, sunny weather.[1]

Austrians faced a number of ecological problems in the 1990s.[1] One of the most pressing is the pollution caused by the staggering increase of traffic through the country.[1] Traffic on the superhighway going through the Brenner Pass has, for example, increased from 600,000 vehicles per year in the early 1970s to over 10 million per year in the early 1990s.[1] One quarter of the traffic crossing Austria consists of semitrailers used for heavy transport.[1] The opening of Eastern Europe has only exacerbated the problem of transit traffic.[1]

The Alpine valleys through which much of this traffic passes are unusually vulnerable to ecological damage.[1] Narrow valleys are not conducive to dissipation of noise or pollutants caused by motor vehicles.[1] Inversions – cold layers of air that trap warm layers of air or warm layers of air that trap cold layers in the valleys and lowlands – also seasonally contribute to the magnitude of the pollution problem.[1]

Austria has negotiated with the EU to set limits on the amount of commercial transit traffic, especially through Tyrol.[1] Work is also under way to develop a "piggy-back" system of loading semitrailers on to flatbed railroad cars in southern Germany and northern Italy, transporting them through Tyrol by rail.[1] Environmentalists have pushed for measures that are more far-reaching.[1] They advocate, for example, digging a tunnel from Garmisch-Partenkirchen in southern Germany to Bolzano in northern Italy.[1]

Pollution is also brought by the weather systems that determine the country's climate.[1] Atlantic maritime weather systems carry pollution into Austria from northwestern Europe.[1] Austria's proximity to industrialized regions of former Communist states, with negligible or no pollution control policies or equipment, combined with the influence of continental weather systems also have proved to be extremely harmful.[1] Mediterranean weather systems transmit industrial pollutants from northern Italy.[1]

As a result of domestic and foreign pollution, 37% of Austria's forests had been damaged by acid rain and/or pollutant emissions by 1991.[1] The damage to forests has had dire consequences, including the decimation of forests that for centuries had protected many Alpine communities from avalanches, erosion, mudslides, or flooding caused by runoff.[1]

The seriousness of the ecological problems confronting the country gave rise in the 1970s to an environmentalist movement.[1] Political parties were formed, and representatives were elected to parliament.[1] A referendum in 1978 closed down a newly completed nuclear power station and turned the country away from the exploitation of nuclear energy.[1] Public opposition in 1984 stopped the planned construction of a hydroelectric power station in a wetlands region.[1]

The country's long-standing commercial use of the Alps for recreational purposes has also come under examination.[1] Extensive tourism places an inordinate amount of pressure on sensitive Alpine ecosystems.[1] Ski runs damage forests, as do summer sports such as off-trail mountain hiking or mountain biking.[1] Many Alpine villages have also grown greatly because of the tourist industry.[1] In extreme cases, they have up to twenty hotel beds for each inhabitant, a ratio that places a disproportionate seasonal burden on communal infrastructures and the environment.[1] For these reasons, efforts have been made to introduce "green" or "soft" forms of tourism that are more compatible with the Alpine environment.[1]

Part of the solution to Austria's ecological problems is being sought in stricter environmental legislation at the domestic level.[1] Ultimately, however, pan-European and global cooperation in the realm of pollution and emission control will be necessary to protect the country's environment.[1]
