Sammanfattning
Can ecosystem services and design strategies for community
engagement be used to mitigate human impact on aquatic
environments? In this thesis the main catchment area of the
river Götaälv in Sweden and specifically the sub-catchment
area between lake Vänern and the sea has been investigated
as a case study to understand how spatial development in key
locations can be used to reduce harmful impact on freshwater
bodies. Investigations have also been done on how spatial
transformation for improving the chemical and ecological status
of freshwater can also contribute to social welfare in urban
environments.
The investigations have been done on different scales. Mapping
on a regional scale defined key locations to intervene in the
sub-catchment area, but also what problems relates to spatial
transformation and what has to be solved within other fields.
One of these locations where then selected as an example
of how spatial transformation on a smaller scale can look like
to improve water status. The transformation is also a critical
reflection of how urban expansion have been relating to water
historically. To support the design of the key location different
principles for spatial water purification have been developed.
All stages of the project were supported by evidence-based
design with different methods such as literature reviews, interviews,
GIS analysis and generative design. Theories around
social ecological urbanism and participatory design was used
to support the project. Ecosystem services have been used to
frame the project and understand the relation between ecological
and social aspects of spatial planning around water.
The most important outcome of the theses has been to distinguish
how architects and planners can approach similar projects
that intends to support better water quality. Mainly in the design
phase it has also been important to clarify how spatial planning
for healthy status of freshwater bodies can be beneficial even
for people and where synergies occur.
