The main focus is on the cultural, solar, and environmental large-scale contexts that impact small traditional agricultural plots, following the technical input data of agrivoltaics solar power or fish-friendly micro hydropower, considering the cultural landscape. The case study on an existing polder addresses several environmental issues, risk management concerns, energy requirements, and aspects of renewable energy transition, including potential solutions and their impact. Cultural landscape, agricultural plot management, and ecology focusing on traditionally inspired design in rural wetland areas in Romania, Technical vs. Humanistic as a solving path through some inspiring "Dyads" is emphasised in the proposed paper.
