The Mühlviertler Ressourcenplan is a instrument of resource planning, that is currently in the process of development. Referring to existing renewable resources and general conditions it modulates an economically optimized scenario for regional energy, food, and organic material supply. Therefore, the method of Process-Network-Synthesis is used. In addition, the scenario will be assessed by ecological and macro-economic indices. The aim of this thesis is based on the example of the Mühlviertel to analyse resource planning concerning its contribution to sustainable regional development. First the objective is to characterize the MÜRP as resource planning instrument by comparing its concept with the planning theory and practical examples of resource planning. Also, its functions are discussed in context of the global resource use conflicts. Further, the MÜRP is evaluated as an instrument for sustainable development. The evaluation frames are based on a sustainable decision making process and the requirements of a working ecosystem. Furthermore the MÜRP is compared with strategies for sustainable regional development. In addition, the connections between the ongoing development process in the region and the MÜRP-Process are discussed. The results of this thesis show that the MÜRP is an instrument to bring up a strategic plan for a development scenario and it can be used for target planning. In context of resource use conflicts the MÜRP-functions are able to integrate sustainable conditions and assess the ecological costs as well as the degree of regional resource supply with renewable resources. Considering the following conditions, the MÜRP is a sustainable planning instrument: The MÜRP-framework must be orientated on the model of the sustainable-egg. Hence, it can be used in the sustainable decision-making process for pre-selection of system variations. Therefore the MÜRP-framework must be orientated on the ecological system borders to maintain the ecological capability of ecosystems. Also the MÜRP has potential to supply the regional self-organisation process and to provide a basis of information to the ongoing initiatives in the region. On the other side they are able to support the implementation of new supply systems. Moreover several instruments of regional-, spatial-, and environmental planning can be used to implement conditions.
