DEGRADATION AND CONTROL PROCESSES

Degradation process:


Due to the permanent sealing as the result of the construction of housing and infrastructure.


Description:


This is associated with land uses involving housing and constructed infrastructure. It constitutes an irreversible loss of soil due to sealing and is related to land planning strategies and the protection of good quality fertile soils.

Importance: great. Comparisons of aerial photographs of peri-urban zones taken at different points in time show the magnitude of this problem



Soil functions affected:


Food production (suppressed), hydrological functions (reduction of water absorption, infiltration and filtration); water courses can be affected by concentrations, generating concentrated flows with greater erosive effects on the soils of surrounding areas; the continuity of biodiversity may become fragmente.



Diagnostic criteria:


Soil quality studies. Studies of the proportion of good quality soils lost and what could be considered acceptable within the framework of sustainable development.



Prevention and control:


Promoting social awareness of the importance of protecting the best quality soils should encourage a form of land planning that takes into account the need to protect the best quality soils. In building projects, the topsoil should be removed and stored so that it could be reused in gardens and parks.
