This study aims to analyze how two faces of agricultural intensificationd i.e. the eutrophication of coastal wetlands together with the proliferation of intensively managed irrigation pondsdaffect local (a-) and inter-local (b-) diversity, and how they interplay configuring regional diversity of chironomid species. We hypothesized that despite the structural simplicity and intensive management of irrigation ponds, they may still be valuable to improve regional diversity of chironomids under the current situation of eutrophication of coastal wetlands.
