This study investigates the often-overlooked phenomenon of land drainage interventions as a means climate change adaptation, focusing on conceptual case from Northern Bohemia, Czech Republic. The intensification agriculture has led to extensive tile systems, which have had significant environmental impacts, including disruption water balance, nutrient leaching, and ecological degradation. With expected alter precipitation patterns increase temperatures, these impacts are likely intensify, leading more frequent droughts pollutant delivery soil bodies. explores options for allocation implementation drainage-related measures such controlled drainage, constructed wetlands, partial elimination mitigate effects, with use readily available archival data well aerial images, current historical soil, use, geomorphological landowner-land user relationships. At two cadastral units local potable resources at hilly Lovečkovicko study, paper proposes conceptual, practical approaches integrating into consolidation processes. Here, eleven sites based cross-intersection above interventions’ criteria were selected, twenty various tentatively designed. categorizes potential proposed three levels: high, medium, low, highlighting feasibility transferability within or similar process.

Wetland management maintains nitrogen (N) removal capacity in mature and overgrown constructed wetlands (CWs). We evaluated whether CW by macrophyte harvesting, subsequent installation of woodchips-based floating beds (WFBs) planted with Glyceria maxima Filipendula ulmaria improved N removal. In sixteen heavily experimental CWs, we applied four treatments: i) only ii) 5% the harvested-CW surface covered WFBs, iii) 20% WFBs cover, iv) a control treatment (heavily overgrown). was determined all at nine occasions. Plant biomass accrual, assimilation, denitrification genes nirS, nirK, nosZI nosZII on plant roots woodchips from were estimated.
