that at least a third of the inner-city reserves can be mobilised
in the short term. Here as well, it is good to differentiate
spatially and consider if mobilisation can be accelerated
through the concerted action of individual
communities, through the communities working with each
other and communities working together with the canton.
However, the readiness of owners to evaluate the potential
is the most common obstacle here as well. Now, more
than in the past, it will depend on being able to, first, awaken
interest in an exchange through an active strategy of
inner development , and second, to activate interest in the
diverse potential through offers, consultations and mutual
planning. This means that, more than in the past, is
will be important to invest in planning support for the
mobilisation of inner development reserves.
A differentiated examination of the temporal availability
and additional tasks needed to mobilise the potential areas
shows that, under these conditions, the readiness of the
landowners to grant building permission would have to
take place in a time frame of ten years at the latest.
Perspectives and recommendations for further steps
The experience with the pilot project supports the concept
that a survey of potential settlement areas can be managed
within a level of appropriate expenditure for the communities.
The technical conditions for the use of an Internet-based
overview and for the evaluation of the data are
now available to all the communities in the canton. During
the pilot project, the canton had already begun to make arrangements
to ensure that communities will have access
to the overviews over the long term. Based on the experiences
with the pilot project, the following recommendations
have been formulated:
a. From the overview of land management in the Canton
of Schwyz
� To agree on performing a regular follow-up of the overviews
in the Canton of Schwyz.
� To prepare regular status reports on the land-use balance in
the canton and to submit the reports to the government.
� To check which special processes of an especially important
nature for a inner development -oriented settlement
policy in the defined spaces in the Canton of
Schwyz can be supported and therefore what special
means can be placed at their disposal.
� To entrust the Federal Office for Spatial Development
with the coordination of the work required.
b. Nationwide support for the implementation of the minimum
strategy: inner development before new development
� To request community and inter-community concepts
and strategies for inner development and to promote
and support them.
� To provide argumentation and implementation help for
a inner development -oriented settlement policy in the
form of instruments and to test and compile examples
of their implementation and make these available to
the communities and cantons.

� To test inter-community cooperation and processes to
establish their positive effects.
c. Gradual expansion of the overviews
� To use the knowledge gained from the pilot project for
a gradual nationwide expansion of the use of the overview
instrument and to make provisions that, starting in
2010, the overviews can be compiled in two to four additional
cantons. The experiences of the Canton of
Schwyz in the follow-up processes should be added to
this information as an update.
� To ensure comparability and a minimum content requirement
for the overviews and to coordinate this between
the cantons.
� To investigate and approve the general legal conditions
and technical prerequisites in the federal and cantonal
governments needed for a nationwide expansion of the
use of this instrument.
