“…As a promising approach, it also has the potential to mitigate the conflict between agriculture, forest management, and environmental protection [23,42,43]. However, restoration efforts require a collaborative effort from policymakers, land managers, and farmers to ensure the long-term success of these restoration projects while also protecting the valuable ecosystem services of wetlands [23,44]. A multiobjective assessment of land-use practice may be necessary to exploit provisioning and regulating ES synergies.…”

Climate change and water scarcity increase the vulnerability of crop production and other ecosystem services (ES) in flood-protected lowlands under a continental climate. Restoration of wetlands leads to a higher water-buffering capacity of the landscape, strengthening various ecosystem services, and fostering adaptation to climatic, ecological, and agricultural challenges. Such restoration efforts require extensive land-use change, leading to trade-offs in provisioning and regulating ES. However, knowledge is limited about these situations, especially in the case of lowland areas. Here, we introduce a hydrological analysis in a 243 km2 flood-protected catchment in the Great Hungarian Plain, mapping the potential hydrological effects of water-retention scenarios on groundwater levels. We point out how the simulated groundwater levels will be used for estimating the changes in crop yields and tree growth (provisioning services). The introduced hydrological analysis and preliminary results for crop-yield estimates suggest a significant and scalable capacity for a nature-based hydrological adaptation: the extent of inundated areas could be increased stepwise and water retention could locally compensate dry periods due to the buffering effect of inundated meanders.

“…The cost-benefit approach has clear advantages over the cost-effectiveness approach . As the third article in the thesis (Warachowska et al, 2023) points out, in the case of the VTT program, the cost-effectiveness approach was sufficient to develop acceptable rules for the inundation of the flood-peak polders, in contrast to a situation where the rules for compensating the damage caused by using the polder remained unclear, which consequently prevented its operation. This latter setup led to a level of social well-being below its potential.…”

“…The third article that makes up my PhD (Warachowska et al, 2023) The institutional frameworks for claiming the inundation of areas are significantly different in terms of clarifying the conditions attached to land ownership in the polders. In the Tisza River case, the legislation reflects the initial assumption that the inundation of a polder area is an event in the public interest to the detriment of private property and that since it is intentional, as it is caused by the opening of floodgates, landowners are entitled to compensation.…”

The dissertation follows an article-based PhD structure, where the summary text contextualizes and synthesizes the three articles of my PhD dissertation. These articles cover the scientific approach and results of separate project-based work carried out along the Tisza River in recent years. I have been involved in these projects as a project leader and analyst. At the Tisza River, the development of flood-peak polders (in line with the Further Development of the Vásárhelyi Plan Program – or VTT according to the Hungarian acronym) was a significant initiative in terms of flood management and rural development in the period 2000-2020, but the assessment of its results from a policy implementation perspective is not unanimous. The aim of the thesis is, among other things, to describe the scientific context of these partly successful (flood management) and partially unsuccessful (rural development, land-use change) results. I believe that without a coherent interpretation, no further progress can be expected in the related policy field, although the reasons for the partial failure will be key issues in the implementation of any climate policy goal requiring territorial adaptation. For this interpretation, I address the development process of the Tisza flood-peak polders through the perspective of Spatial Flood Risk Management (SFRM), an emerging approach. The thesis reflects on the issues that gave rise to it, its characteristics, and why and how it can be used to support the implementation of flood risk management projects that require the involvement of private land. This is one stream of the work. Another source of added value of the PhD thesis is that it contributes to understanding the impact of technological development on the potential conducting economic analyses. Technical advances in flood-risk mapping have now made it possible to apply a reliable cost-benefit- and, consequently, a provider-beneficiary approach to the organization of flood defense from a spatial perspective, which includes the value of flood risk reduction among the benefits. Moreover, the flood-risk modification potential of these spots (sites) can also be expressed, depending on assumptions about land use. This new situation will allow more effective solutions to flood-risk reduction to be developed. This can be exploited by making a cross-sectoral comparison of public and private impacts and their relationship to land use alternatives in a monetizable form. The dissertation explores these potentials based on the experience gained from the flood-peak polder development process of the Tisza River. The second part consists of the articles that provide the background for the synthesis and the summary of the work. The first paper, Reducing flood risk by effective use of flood-peak polders: A case study of the Tisza River (Ungvári & Kis, 2022b), presents the methodological development and results of a flood-risk calculation-based economic support system for the management of the Tisza River flood-peak polders. The second, Combining Flood Risk Mitigation and Carbon Sequestration to Optimize Sustainable Land Management Schemes: Experiences from the Middle-Section of Hungary's Tisza River (Ungvári, 2022), presents the results of cost-benefit analyses that support the multi-criteria utilization of land suitable for flood-risk mitigation. The third article, Social, economic, and legal aspects of polder implementation for flood risk management in Poland and Hungary (Warachowska et al., 2023), compares the regulatory approaches underlying the operation of flood-peak polders on the Tisza River and the Warta River in Poland.
