Assess students' ability to analyze trade-offs between biodiversity conservation, agricultural productivity, and water allocation in a temperate river basin. Tasks include interpreting hydrological and species-distribution data, estimating simple water budgets and irrigation demands, comparing ecological and crop-yield outcomes under alternative allocation scenarios, evaluating stakeholder objectives and policy instruments (e.g., environmental flows, water pricing, incentives), and proposing evidence-based management strategies that balance ecosystem services, food production, equity, and uncertainty. Requires quantitative reasoning, scenario analysis, and written justification of recommended trade-offs.
