<strong>The</strong> <strong>Local</strong> <strong>Agenda</strong> <strong>21</strong> <strong>Planning</strong> <strong>Guide</strong><br />
Prior to 1992, structural plans for the city of Gothenburg did not contain an analysis of the balance of materials. In preparation for<br />
the city’s 1993 Comprehensive Plan, Gothenburg developed “material cycles” for water and nitrogen (Nielsen et al., 1992). <strong>The</strong> aim<br />
was to stimulate informed public debate on eco-cycle issues in the city and to ultimately influence the planning process itself. Later,<br />
a study of the city’s carbon cycle was also completed.<br />
Measurement of the water cycle in Gothenburg provided a flow representation that linked land, water, and air, and crossed municipal<br />
and regional boundaries. It also identified and described the cycles that link human activities to water sources, pollution, and liquid<br />
and solid waste.<br />
Because nitrogen cannot be seen, the nitrogen cycle is less understood than the water cycle. However, nitrogen is associated with a<br />
number of environmental problems and is recognized as an important element to measure and report to the public. <strong>The</strong> nitrogencycle<br />
model developed in Gothenburg included, and demonstrated the linkages between, many urban activities such as<br />
transportation, heating, industrial production, cultivation, food, waste deposits, and sewerage systems. <strong>The</strong> presentation included<br />
facts on the average citizen’s annual nitrogen emissions from energy use in the home, in transport, and in the generation of solid and<br />
liquid waste.<br />
Describing the materials cycles for one or more damaging substances was considered important as a means of explaining the need to<br />
keep natural cycles intact if they are to be sustained. For this reason, material cycles for toxins were tested as an educational tool.<br />
Gothenburg explored the development of a material cycle for chlorinated benzenes and household solvents. Due to an effective<br />
educational program that led to a reduced use of chlorinated benzenes, and due to the fact that household solvents are almost<br />
exclusively emitted into the air and therefore impossible to track, these substances proved to be poor examples for promoting the<br />
discussion of toxic material cycles. <strong>The</strong> strength of eco-balancing lies in its ability to track the flow of a substance.<br />
<strong>The</strong> anticipated results from a study of a quicksilver (mercury) cycle in Gothenburg are expected to be more useful. Mercury is still<br />
used and does not evaporate, and is therefore easier to trace.<br />
<strong>The</strong> material cycles method has been used to compile information on the overall state and functioning of the city’s “metabolism.”<br />
Based on this information, discussions with politicians were initiated. As a result of these discussions, the city’s <strong>Planning</strong> Committee<br />
decided to include questions about sustainability and eco-cycles into the regular consultation process for the Structural Plan.<br />
Between June and September 1992, a public consultation was conducted with more than 100 groups and organizations. Discussions<br />
were guided by questions regarding the city’s metabolism, eco-cycles, and sustainability. <strong>The</strong> outcomes of these consultations have<br />
been subsequently integrated into the Structural Plan. One priority identified was the need to reduce the sprawl of residential<br />
development on the urban periphery by restricting new suburban housing developments.<br />
Eco-balancing studies in Gothenburg have increased awareness about the linkages between land development and material flows and<br />
cycles in the city and the local environment. <strong>The</strong>y have educated policymakers and residents about the metabolism of the city and<br />
about the imbalances in the city’s imports of materials and exports of wastes. <strong>The</strong>se studies have mobilized support for work on<br />
sustainability and have provided the opportunity for consideration of ecological cycle issues in urban planning. <strong>The</strong> future challenge<br />
is to develop an eco-balancing tool or model that will have more direct input into the structural planning process.<br />
