TL;DR: In this article, the influence of climate change and land development on future flood risk for selected Austrian flood-prone municipalities is analyzed. But, the impact of these factors vary strongly across the different cases.
Abstract: This paper analyses the influence of climate change and land development on future flood risk for selected Austrian flood-prone municipalities. As part of an anticipatory micro-scale risk assessment we simulated four different inundation scenarios for current and future 100- and 300-year floods (which included a climate change allowance), developed scenarios of future settlement growth in floodplains and evaluated changes in flood damage potentials and flood risk until the year 2030. Findings show that both climate change and settlement development significantly increase future levels of flood risk. However, the respective impacts vary strongly across the different cases. The analysis indicates that local conditions, such as the topography of the floodplain, the spatial allocation of vulnerable land uses or the type of land development (e.g. residential, commercial or industrial) in the floodplain are the key determinants of the respective effects of climate change and land development on future levels of flood risk. The case study analysis highlights the general need for a more comprehensive consideration of the local determinants of flood risk in order to increase the effectiveness of an adaptive management of flood risk dynamics.

TL;DR: In this paper, the authors investigated the determinants influencing the willingness of landholder farmers to participate in voluntary land consolidation processes and found that land consolidation is a proper tool to solve inefficiencies in agricultural production, as it enables consolidating plots based on the consent of landholders.
Abstract: In many African countries and especially in the highlands of Ethiopia—the investigation site of this paper—agricultural land is highly fragmented. Small and scattered parcels impede a necessary increase in agricultural efficiency. Land consolidation is a proper tool to solve inefficiencies in agricultural production, as it enables consolidating plots based on the consent of landholders. Its major benefits are that individual farms get larger, more compact, contiguous parcels, resulting in lower cultivation efforts. This paper investigates the determinants influencing the willingness of landholder farmers to participate in voluntary land consolidation processes. The study was conducted in Gozamin District, Amhara Region, Ethiopia. The study was mainly based on survey data collected from 343 randomly selected landholder farmers. In addition, structured interviews and focus group discussions with farmers were held. The collected data were analyzed quantitatively mainly by using a logistic regression model and qualitatively by using focus group discussions and expert panels. According to the results, landholder farmers are predominantly willing to participate in voluntary land consolidation (66.8%), while a substantive fraction of farmers express unease with voluntary land consolidation. The study highlighted the following four determinants to be significant in influencing the willingness of farmers for voluntary land consolidation: (1) the exchange should preferably happen with parcels of neighbors, (2) land consolidation should lead to better arranged parcels, (3) nearness of plots to the farmstead, and (4) an expected improvement in productivity. Interestingly, the majority of farmers believes that land consolidation could reduce land use conflicts. The study provides evidence that policymakers should consider these socio-economic, legal, cultural, infrastructural, and land-related factors when designing and implementing voluntary land consolidation policies and programs.

TL;DR: In this article, the authors present and assess the case of an inter-municipal cooperation in Austria which aims to alleviate flood risk and coordinate planning activities based on a catchment approach.
Abstract: River floods usually do not stop at administrative borders. The respective location of municipalities along a river creates different options and dependencies, commonly referred to as upstream-downstream relations. This regional dimension of flood risk calls for catchment-based approaches in flood risk management as advocated by the EU Flood Directive. In this paper we present and assess the case of an inter-municipal cooperation in Austria which aims to alleviate flood risk and coordinate planning activities based on a catchment approach. The authors apply an established model of water governance to characterise the governance features and to assess the governance qualities and governance capacities of the inter-municipal cooperation. Findings show that the selected case qualifies as a suitable governance instrument to address the main policy objectives. Existing functional ties, shared (flooding) experiences and mutual trust mark key success factors, indicating that proximity - in its many different forms - is crucial to overcome power asymmetries and spatial misfits in catchment-based flood risk management. However, inter-municipal cooperation is weak when it comes to ensuring binding land use regulations, showing the need for a complementary use of governance arrangements and formal instruments of regional land use planning in flood risk management.

TL;DR: In this paper, the authors explored the minor variations of ecosystem services provided by the particular land use types of the study area and used elasticity techniques to analyse the response of land use land cover changes over the ecosystem service valuation, which showed that the overall built-up area has increased by 29.14% since 1999, while the overall water-body has decreased by 15.81%.

TL;DR: In this paper, the authors examined the use of interactive models of research in the US regional integrated scientific assessments (RISAS), using as a case study the climate assessment of the Southwest (CLIMAS).
Abstract: This paper examines the use of interactive models of research in the US regional integrated scientific assessments (RISAS), using as a case study the climate assessment of the Southwest (CLIMAS). It focuses on three components of regional climate assessments: interdisciplinarity, interaction with stakeholders and production of usable knowledge, and on the role of three explanatory variables––the level of ‘fit’ between state of knowledge production and application, disciplinary and personal flexibility, and availability of resources—which affect the co-production of science and policy in the context of integrated assessments. It finds that although no single model can fulfill the multitude of goals of such assessments, it is in highly interactive models that the possibilities of higher levels of innovation and related social impact are most likely to occur.
