Framework for a spatial Decision Support Tool for policy and decision making

The main challenge of developing of a spatial DST (Decision Support Tool) to support the decision making on future livestock production will not be a technical one, but instead a challenge of meeting the con-text requirements of the tool, such as the characteristics of the country-specific spatial plan-ning and decision-making process, the wishes of the potential users of the tool and its output as well as the country-specific policies and regulations. The spatial DST which is being pro-posed in this report therefore does not include complex and state-of-the-art GIS techniques, but instead tries to be as clear and simple as possible, in order to give the potential users a full understanding during the analysis process and with using the output of the tool. A spatial DST can easily become a ‘black box’ if the users do not fully understand the limita-tions of the tool and its output. Despite the fact that output maps of GIS systems may look very detailed and suggest a high degree of accuracy, they are often not. This will entirely de-pend on the availability of reliable and detailed input data. Most likely, many of the produced output maps should be used in an indicative way only. Therefore, the output of the spatial DST needs to be accompanied by supporting information on the reliability of the output and the shortcomings due to unreliable or missing input data, as well as the consequences for use of the output. Therefore, a comprehensive meta-data assessment system is proposed as an in-tegrated part of the spatial DST. The distribution of the output will also require tools to pro-duce more sketch-like presentations, e.g. using fuzzy borders and aggregated maps, which are another important feature of the spatial DST.
