This subsection presents the key analytical outcomes derived from the multi-objective optimisation framework applied across the OPTAIN case studies. Building on simulation-based assessments of Natural Small Water Retention Measures (NSWRM), optimisation analyses were conducted to explore how different combinations and spatial allocations of measures perform when evaluated against multiple, potentially competing objectives.
Rather than identifying a single optimal solution, the optimisation process generated sets of Pareto-optimal portfolios, representing efficient trade-offs between water retention efficiency, nutrient retention efficiency, agricultural productivity, and cost-related metrics. This approach makes explicit the structural tensions between environmental performance and socio-economic considerations, highlighting that improvements in one objective may require compromises in another.
By comparing optimisation results across the Boreal, Continental and Pannonian regions, the project provides structured insight into how regional context influences trade-off patterns and portfolio efficiency. The following sections synthesise these optimisation outcomes and distil cross-regional lessons derived from model-based scenario analysis and stakeholder-informed evaluation.
