Land use
The Information System on Prague
Environment (IO?IP) also comprises a Surface Types and Greenery
register which contains data on different land lots and aggregated
data for each cadastral area. The information is presented in the
Surfaces and Greenery in Individual Cadastral Units publication
(IMIP, 1995) the first edition of which has already been sold out.
The register was updated in 1995. Further updating is not envisaged
at the moment as it is too cost- and labor-intensive. At the moment, only the updated data taken
over from the Real Estate Cadastral Register is available (data
aggregated in individual cadastral units).
Chemical
contamination of soil
The year 1997
witnessed yet another phase of the soil contamination monitoring
project the purpose of which was to determine in detail the
contamination level of the topsoil cover in the territory of Prague.
In accordance with
requirements of the Department of Environment of the Prague City
Hall the site selection and monitoring were focused on historical
soil contamination sites, on a more detailed monitoring of areas
where some contamination had already been identified, and on some as
yet unmonitored sites in the territory of Prague. Furthermore, the
monitoring network was expanded to comprise the city-planning
district of Zbraslav (with an emphasis on the quality of children’s
playgrounds and sandboxes). Repeated measurements were conducted in
the Prague 12 - Modrany district where anomalous contamination
levels had been discovered in 1996. In accordance with requirements
of the customers the selected monitoring sites were also consulted
and coordinated with the Czech Geological Institute which implements
a geochemical mapping project of the Prague agglomeration.
This year
samples were taken in regularly monitored sites and analyzed as
well.
Regular
Monitoring of the Living Component on Selected Sites
To enable
assessments of the ongoing changes of the enviroment in Prague the
living component is also monitored. As a matter of fact, data
pertaining to lower animal species is often indicative of adverse
consequences of environmental deterioration wiht respect to humans.
The changes that are identified demonstrate the aggregate inpact of
all factors which are often monitored separately. Within the Prague
Information Environment System the biomonitoring programme is
conducted by the Czech Association of Nature Conservationists on the
following six natural model sistes generally in five-year cycles:
• Divoká Šárka
(1984, 1988, 1993)
• Prokopské
Valley (1984, 1989, 1994)
• Pitkovické
Valley and Uhríneves Warren (1985, 1990, 1995)
• the confluence
of the Vltava and Berounka Rivers (1986, 1991, 1996)
• Troja Basin
(1987, 1992, 1997) |
