AFFOREST sDSS: a metamodel based spatial decision support system for afforestation of agricultural land

et al. 2005

Abstract. The concept and structure of the Spatial Decision Support System AFFOREST sDSS dealing with environmental performance (EP) of afforestation on agricultural land in northwestern Europe, is presented. EP is defined in terms of three environmental impact categories: (1) carbon sequestration (2) groundwater recharge and (3) nitrate leaching. The core of the sDSS is a raster based geographical database which allows for queries addressing 14 types of questions on where, how and how long to afforest in order to reach a desired EP or change in EP due to afforestation of the agricultural land. First the study area is differentiated according to the site conditions (based on soil texture, soil drainage, initial land use, yearly average precipitation, and yearly average N deposition. Then the EP for every site class is computed as a function of time using the VSAM metamodel. VSAM results from a conceptual simplification of an existing mechanistic point model, the forest process model SMART2. Input data for the metamodel are limited to the classified site conditions, the tree species used for afforestation, the afforestation strategy and the evaluation time. Besides limiting the data requirements, the metamodel approach allows for rapid and flexible computations on large numbers of pixel classes. Finally, depending on the type of question, the sDSS creates georeferenced outputs based on SQL-type spatial or attribute queries and more advanced multiple goal programming techniques.

This paper describes the multicriteria process used to evaluate flood control options for the catchment of Livramento creek in the peninsula of Setúbal, in Portugal. In the structuring phase, the environmental, social, and technical dimensions were identified. The MACBETH approach -Measuring Attractiveness by a Categorical Based Evaluation Technique -was then used to construct a quantitative evaluation model based on qualitative value judgments formulated by a group of experts from different technical and scientific fields. The model enabled the overall benefit associated with each option to be appraised, and extensive sensitivity analyses to be performed.

“…Lately, there is a tendency overcome this shortcoming by using multicriteria evaluation methods. This type of research is relatively new with a limited numbers of applications (Janssen, 1992;Turner & Bateman, 2001;Moriki, et al, 1996). This methodology allows simultaneous analysis of economic social & environmental data.…”

The understanding of marine eutrophication in semi enclosed areas due to agricultural runoff, assumes a more integrated approach taking into account the agricultural watershed, seasonal patterns of soil nutrients, rates of erosion and vegetation types. In the present case study in the Gulf of Geras, Lesvos, Greece, the transport of dissolved and solid phase nutrients of terrestrial origin to the marine environment was studied in detail using mathematical modelling. Fifteen criteria describing environmental and socioeconomic aspects were analysed using multi criteria choice methods and a number of scenarios were evaluated. Parallel to that an eutrophication model was used to describe the problem of eutrophication in the marine environment and also to assess the environmental impact from the proposed scenarios. The emphasis was placed in the interconnection between Mediterranean type ecosystem and marine coastal eutrophication. The results showed that the coupling of multi criteria analysis together with simulation modelling, provide a powerful tool for integrated coastal management practices and assessing eutrophic trends in semi enclosed areas.
