Exploitation of natural forests forms expanding frontiers. Simultaneously, protected area frontiers aim at maintaining functional habitat networks. To assess net effects of these frontiers, we examined 16 case study areas on five continents. We (1) mapped protected area instruments, (2) assessed their effectiveness, (3) mapped policy implementation tools, and (4) effects on protected areas originating from their surroundings. Results are given as follows: (1) conservation instruments covered 3–77%, (2) effectiveness of habitat networks depended on representativeness, habitat quality, functional connectivity, resource extraction in protected areas, time for landscape restoration, “paper parks”, “fortress conservation”, and data access, (3) regulatory policy instruments dominated over economic and informational, (4) negative matrix effects dominated over positive ones (protective forests, buffer zones, inaccessibility), which were restricted to former USSR and Costa Rica. Despite evidence-based knowledge about conservation targets, the importance of spatial segregation of conservation and use, and traditional knowledge, the trajectories for biodiversity conservation were generally negative.

Context: Maintaining functional green infrastructures (GIs) require evidence-based knowledge about historic and current states and trends of representative land cover types. Objectives: We address: (1) the long-term loss and transformation of potential natural forest vegetation; (2) the effects of site productivity on permanent forest loss and emergence of traditional cultural landscapes; (3) the current management intensity; and (4) the social-ecological contexts conducive to GI maintenance . Methods: We selected 16 case study regions, each with a local hotspot landscape, ranging from intact forest landscapes, via contiguous and fragmented forest covers, to severe forest loss. Quantitative open access data were used to estimate (i) the historic change and (ii) transformation of land covers, and (iii) compare the forest canopy loss from 2000 to 2018. Qualitative narratives about each hotspot landscape were analysed for similarities (iv). Results: While the potential natural forest vegetation cover in the 16 case study regions had a mean of 86%, historically it has been reduced to 34%. Higher site productivity coincided with transformation to non-forest land covers. The mean annual forest canopy loss for 2000–2018 ranged from 0.01 to 1.08%. The 16 case studies represented five distinct social-ecological contexts (1) radical transformation of landscapes, (2) abuse of protected area concepts, (3) ancient cultural landscapes (4) multi-functional forests, and (5) intensive even-aged forest management, of which 1 and 4 was most common. Conclusions: GIs encompass both forest naturalness and traditional cultural landscapes. Our review of Pan-European regions and landscapes revealed similarities in seemingly different contexts, which can support knowledge production and learning about how to sustain GIs.

In light of the increased frequency of multi-hazards, the dynamics of vulnerability across time, space, and different hazards emerges as an intriguing but challenging research topic. Within multi-hazard contexts, both the impacts of hazards and mitigation strategies can augment vulnerabilities, adding layers to the complexity of multi-risk assessments. Delving into these interactions, this study aims to analyse new connections in rising vulnerability that result from impacts and adaptation options, as well as their implications, putting co-occurrent powerful river flood events and the COVID-19 pandemic in Romania under the magnifying glass, taking 2020 and 2021 as references. The proposed framework relies on an impact chain that was enhanced to include new elements (i.e. augmented vulnerabilities and derived impacts) and links (i.e. connections that describe the augmentation of vulnerability), which were also used to rank the vulnerabilities based on their augmentation. The impact chain draws on various data and information sources, including the scientific literature, the feedback of first responders, reports, legislative documents, official press releases, and news reports. This research work makes a significant contribution to the field of disaster risk reduction (DRR) by broadening the purpose of the impact chain, transforming it into a first-hand, semi-qualitative tool for analysing vulnerability dynamics.

Forest ecosystems are a prime example of the heated debates that have arisen around how forests should be managed, and what services and benefits they should deliver. The European transitions in governance to and from communist regimes have had significant impacts on forests and their management. Unstable legislative and institutional changes prior to, during, and after a communist regime, combined with unique remnant areas of high-conservation-value forests, make Romania an ideal case study to explore the social–ecological transitions of forest landscapes. The aim of this paper is two-fold. First, we present the origins of, the evolution of, and the current state of forest management and ownership in Romania during transitions between the pre-communist (–1945), communist (1945–1989), and EU periods (2007–). Second, we focus on the enablers and barriers in Romania towards sustainable forest management as defined by pan-European forest policies. We used a semi-systematic, five-step scientific literature review on forest ownership, governance, and management in Romania. The analysis shows that both enablers (e.g., forest certification) and barriers (e.g., redundancy and the questionable effectiveness of the network of protected areas; illegal, unsustainable, and unreported logging; loopholes in the legislative framework) have contributed to the current approaches to interpreting forests, forestry, and forest management. The installation of the communist regime translated into sustained wood yield forest management under singular forest ownership, which opposed the previous system and forest ownership pluralism. In the post-communist period, forestland restitution led to significant legislative changes, but forest management must still confront remnant elements of the communist approach. Both communist and post-communist policies related to forests have shaped the evolution of forest landscape management in Romania, thus stressing the need to learn from the past towards securing sustainable forest management into the future. These lessons provide insights on both positive and negative drivers of forest management, which can contribute to smooth future transition towards more sustainable forest management practices.

Multi-hazard risk perception is an emerging research topic that has been gaining more and more interest since the beginning of the Covid-19 pandemic, due to the unprecedented interactions between the management practices of the pandemic and of other co-occurring natural hazards, and to the compounded impact of these multi-hazards. This paper aims to investigate the specialization and study level-dependent differences concerning multi-hazard risk perception and hazard-related education insights of future potential specialists in natural hazard-induced risk management and tourism reconstruction. These differences were explored by applying a multi-layer questionnaire on 547 Geography and Tourism students and graduates from two universities in Iași City (Romania) and Novi Sad (Serbia), and performing descriptive and differential statistical analyses. The statistically significant differences that emerged refer to estimations of the impact level of the Covid-19 pandemic and of other natural hazards at different spatial scales and on different socio-economic activities, on the training/career of the respondents, and to the hazard-related education improvements. Up to date, none of the papers in the existing literature integrate both the Covid-19 pandemic and the co-occurrent natural hazards as objects of students' perception, which makes the present study a starting point for such research endeavours.

The occurrence of flood events amid the COVID-19 pandemic represents a prominent part of the emerging multi-hazard landscape, as floods are one of the most frequent and destructive natural hazards. This spatial and temporal overlap of hydrological and epidemiological hazards translates into compounded negative effects, causing a shift in the hazard management paradigm, in which hazard interaction takes centre stage. This paper calls into question whether the river flood events that occurred during the COVID-19 pandemic in Romania and the way that they were managed had an impact on the infection with the SARS-CoV-2 virus at county scale. To this end, hazard management data concerning the flood events that were severe enough to impose the evacuation of the population were corroborated with COVID-19 confirmed cases data. A definite link between the flood events and the dynamics of COVID-19 cases registered in the selected counties is difficult to identify, but the analysis shows that all flood events were followed by various size increases in the COVID-19 confirmed cases at the end of the incubation time range. The findings are critically interpreted by providing viral load and social-related contexts, allowing a proper understanding of the interactions between concurrent hazards.
