Soil evaluation is particularly significant in ecologically sensitive areas already sustainable urban development. This is why subject to heavy use where there is great on-going demand for building and development land. Such preventive soil protection must be reinforced in areas include the urban agglomerations and city regions within and on the edges of the Alps. municipal activities in general, but in spatial planning in particular." The aim of soil evaluation is to steer development to ecologically compatible sites which make spatial (TUSEC-IP guiding principle, 2002) planning sense from the point of view of soil protection, and to promote urban planning concepts which protect the soil. This will help to achieve broad acceptance of the planning procedures and greater planning certainty. From the point of view of spatial planning, this entails evaluation of soil quality with the natural properties, functions and capabilities of the existing soils in a way which allows the results to make a contribution to the planning process and be put to practical use. One key challenge will be to transfer the soil evaluation of natural soil functions into planning evaluation of the suitability for use. Development of applied soil evaluation depends on close cooperation between soil experts and planners. The TUSEC-IP project aims to promote active cooperation between soil protection and spatial planners on an international scale. The aim is to illustrate that the problems of land consumption and soil pollution in cities and municipalities can only be solved by a joint effort. Soil evaluation can be a central instrument for preventive soil protection if it is coordinated to soil protection concerns in spatial planning. Evaluation of soil functions and capabilities allow to visualise the value of soil in the urban natural balance and in a social context, illustrating that soils in city regions are more than just a surface and a site for building use. As an instrument for preventive soil protection, soil evaluation should set new priorities for sustainable development of the habitat subject to the greatest human use. At the end of the three-year project period, this brochure offers brief two-page articles presenting the results obtained by the project partners and the individual working groups. These are not only self- contained individual articles provided by the project teams but modules from individual work packages which are used to collate the results of the individual parts of the project into a transnational overall result. 3 Introduction Soil Protection in City Regions Soil quality, urban environment and ideal concepts The development of protection measures should A third way of looking at soil protection would be to Many of these purposes result not only in soil distinguish between whether there is a primary name key concepts. Even if soils are not directly degeneration, but also in extensive soil destruction, interest in the soil functions, or in preserving a visible, they have a great effect on the other elements caused by soil excavation with total erosion. Today it soil structure with certain morphological of a landscape and are associated with these other is the cities which see the greatest erosion rates. Soil characteristics and origin, or whether soil is elements. destruction also consists of sealing the soils, considered in the overall context with certain The ideal concept of local identity which causes the although sealing does not necessarily have to imply ideal concepts. peculiarities of many places and their landscapes is the total destruction of soil functions. based on the features of the local soils. Concepts make it easier to gear soil protection to the In the city context, soils get a new environment, Notions of protection are anthropocentric.

They are not limited Features of this environment include construction As far as implementing soil protection is concerned, to evaluating a few soil properties as is the case with work, substrates forming soil from relocated soils, on the one hand, quality targets for soils have been soil functions. They are therefore an instrument for from exposed rock or a large number of substrates developed.

When it comes to quality objectives for city soils, infiltrating and settling on the soil (photo 1-4), first it is important to look at the capabilities expected pollution and compaction from heavy machines The anthropocentric approach contrasts with the of city soils, i.e. what is soil needed for in the city (photo 5, 6), but also segmenting of water catchment protection of soil itself and soil in the landscape context? Soil is used for highly varied purposes, as areas through urban drainage and sealing, and also and as part of the landscape. illustrated by the following examples: as a result of care and maintenance measures which This has nothing to do with the concept of soil prevent soil development through weathering and • Housing, traffic, commerce, industry, administration functions to preserve the way a soil works, but looks dust infiltration. •Green spaces at the protection of the individual morphological • Health care, prevention of pollution, fine dust, structure of every soil and the local environment in overheating which a soil has been developed.
