The prevention of soil sealing (Pologne)

Zapobieganie zasklepianiu gleb (Polish)

Description

The prevention of soil sealing is an approach in which stakeholders are making spatial planning decisions based on the new map of soil sealing, in case of protecting the most valuable soils.

Aims / objectives: The aim of this approach is to show how spatial planning decisions, should be made by taking into account the soil sealing problem. As the consequence of urbanization pressure, the urban sprawl is crossing municipal boundaries of Poznań. In the whole study site area, 53,3 % are arable lands, located mostly on loams, silts or sandy clay soils. Wielkopolska province has got the highest farm productivity per ha in Poland. Based on EEA data, sealed surfaces constitute 16 % of the city area. Soil sealing problem is a consequence of the urban sprawl process, which affects mainly the municipalities near by the Poznań city borders. To support decision-making in municipalities spatial planning offices, the data from the soil sealing maps is used to select the most appropriate areas to build new houses mostly on low quality soils.

Methods: Land use maps of at least 10-meter resolution are produced for two historical periods
through classification of the satellite images and using available local land use
information. The information on land use change is superimposed on maps
characterizing soil quality in order to detect to what extend the urbanization took place
on valuable soils. The new sealed area, reflecting the built up sprawl of at least last 15
years, consists with expansion of the following land use classes: continuous residential
area, commercial/industrial area and transport facilities. The soils under these new land
use types fully lost their environmental functions. In the soil sealing forecasts the
Cellular Automata-based Metronamica model is used. The final maps consist of the spatial planning aspect, soil sealing area and the scientific comment about the soil sealing problem.

Principaux objectifs de l'Approche
The Approach focused on SLM only

The main aim of this Approach is to utilize soil agricultural maps and provide information on quality of sealed soils. Send those maps to the municipal authorities, with a scientific comment on the problem. For the whole province, these maps should be made based on the digital soil maps in scale 1:25 000.

The SLM Approach addressed the following problems: The best type of soil is being sealed by new house constructions sites. People from the city center are moving out to municipalities which are near by the border of the city. They are building their houses mostly on agricultural fields in a chaotic way, in much cases on the highest quality soils. This urban sprawl process, affects negatively the soil ecosystem services by the soil sealing and also decrease the quality of inhabitants life.

  • Cadre institutionnel: In Poland, for every area there were made soil maps in scale 1:5000 and 1:25000. On those maps besides soil data there is also information about house areas and land use types. Most of those maps are still only in paper version, which makes it very hard to use them in spatial planning. Treatment through the SLM Approach: We will digitize the paper version of soil maps for the municipalities, and also update the map content about the land use.

Analyses d'impact et conclusions

Impacts de l'Approche
Non
Oui, un peu
Oui, modérément
Oui, beaucoup
Est-ce que l'Approche a aidé les exploitants des terres à mettre en œuvre et entretenir les Technologies de GDT?

It had raised the awareness about the value of soil ecosystem services, and had shown how big is the scale of soil sealing. This information have started to be very useful in case of taking new spatial planning decisions by the planners.

x
Est-ce que l'Approche a autonomisé les groupes socialement et économiquement défavorisés?

This isn't connected with the soil sealing threat

x
Est-ce que l'Approche a amélioré les questions foncières et des droits d'utilisation qui entravent la mise en œuvre des Technologies?

x
Did other land users / projects adopt the Approach?

Our every stakeholder have adopted the Approach.

x
Principale motivation des exploitants des terres pour mettre en oeuvre la GDT
Durabilité des activités de l'Approche
Les exploitants des terres peuvent-ils poursuivre ce qui a été mis en oeuvre par le biais de l'Approche (sans soutien extérieur) ?

Yes, they can continue the Approach activities without support. But we are opened for cooperation/consulting if there will be a need to make some improvements in this Approach.

Conclusions et enseignements tirés

Points forts: point de vue de l'exploitant des terres
Points forts: point de vue du compilateur ou d'une autre personne-ressource clé
  • The analysis are made base on the low scale maps : 1:5000 and 1:25000. (How to sustain/ enhance this strength: Update the land use information in spatial data format)
Faiblesses/ inconvénients/ risques: point de vue de l'exploitant des terrescomment surmonter
Faiblesses/ inconvénients/ risques: point de vue du compilateur ou d'une autre personne-ressource clécomment surmonter
  • The commune authorities don't think about long therm consequences in soil loss. They don't see soil sealing as a threat. Raise the awareness about soil ecosystem services, especially about soil sealing threat. Showing them on the maps, the results of various prediction model, in which the urban sprawl will be still uncontrolled.
