To reach an Ecological Sustainable Development, Sweden has established environmental quality objectives. Green spaces are attractive for exploitation and in Sweden the access to large jointly green spaces has decreased, which has impact on humans recreation and the biodiversity. The economic aspect has great impact on the planning process which gives indications that the environmental objective may collide with other sector goals within the municipality. The thesis overall aim is to see how the management by objectives for the green spaces implements and how the green spaces is handled in the planning process in a specific case. The thesis builds on a content analysis, strategic interviews and a case study. The implementation of the interim target: Program and strategies for green spaces does not function according to the intention with the environmental objectives. Strong economical incitements and a political will that is locked in the logic of competitiveness, makes the sustainable ecological management impossible in practise. The management by objectives for the green spaces falls in the shadow of other sector goals. The ecological aspects have low priority, which leads to a decision process that strives for ecological sustainability, yet are an vision for the future according to the case study.
