“…Heat stress, insects, pests, and diseases are serious problems that climate change appears to be exacerbating. Rural hills and mountainous communities are expected to be affected more due to their extensive dependence on climate-sensitive livelihood options and limited adaptive capacity [46].…”

We reviewed 76 climate change adaptation projects that were operational between 2010 and 2020. The review was followed by office and field visits for verification. The office visit helped crosscheck the findings, and the field observations carried out between December 2020 and April 2021 asked 24 key informants and collected supplementary information appraisal and indicator development. Of the CCA projects studied, the most (n = 48, 32%) were community-based initiatives, while the least (n = 12, 8%) were ecosystem-based interventions. The main environment-centered projects were Ecosystem-based Adaptations and Ecosystems Protecting Infrastructure and Communities (EPIC) while Enhanced Action of Inclusive CSOs for Participation in Climate Resilient Economic Growth (UTHAN), Initiative for CCA (ICCA), Support to Rural Livelihoods and Climate Change Adaptation in the Himalayas (HIMALICA), etc., adaptation projects were community-based. Capacity building and awareness-raising were the major thrust of the CbA projects, while the abatement of climate vulnerabilities and risks through nature-based solutions were priorities of EbA. Payment for Ecosystem services is a nature-based solution that can play a role in enhancing adaptation to climate change at a local scale by adopting community-based and culturally appropriate methods and enhancing and incentivizing adaptation measures and capacities. A set of 11 criteria and 40 indicators comprised the institutional and behavioral responses and the use of technologies, and the design of climate-resilient plans and climate-smart practices were proposed as appraisal measures to evaluate the success of CCA interventions. The importance of criteria and indicators lies in the fact that such a comprehensive assessment would lead to effective and efficient adaptation projects, which could help benefit beyond the borders. It also furthers ongoing adaptation interventions and is set to be an integral part of associated studies and monitoring and review of new adaptation interventions.

“…As pointed out by [ 23 ], slope instability is one the most widespread natural hazards; although it is not generally perceived as being as disastrous as other hazard types it can have a profound impact on populated areas. In-depth investigation of such events requires interdisciplinary approaches [ 24 ], which take into account not only geomorphological or geological factors, but also political, economic and social aspects. Natural hazards like landslides are aggravated by anthropogenic factors, such as: accelerated constructions, tree-cutting on steep slope areas, and obstruction of the drainage system [ 25 ].…”

Romania is one of the countries severely affected by numerous natural hazards, where landslides constitute a very common geomorphic hazard with strong economic and social impacts. The analyzed area, known as the “Ciuperca Hill”, is located in Oradea (NW part of Romania) and it has experienced a number of landsliding events in previous years, which have endangered anthropogenic systems. Our investigation, focused on the main causal factors, determined that landslide events have rather complex components, reflected in the joint climatological characteristics, properties of the geological substrate, and human activity that further contributed to the intensive change of landscape and acceleration of slope instability. Analysis of daily precipitation displays the occurrence and intensive distribution between May and September. Higher values of rainfall erosivity (observed for the 2014–2017 period), are occurring between April and August. Erosivity density follows this pattern and indicates high intensity events from April until October. SPI index reveals the greater presence of various wet classes during the investigated period. Geological substrate has been found to be highly susceptible to erosion and landsliding when climatological conditions are suitable. Accelerated urbanization and reduced vegetation cover intensified slope instability. The authors implemented adequate remote-sensing techniques in order to monitor and assess the temporal changes in landslide events at local level. Potential solutions for preventative actions are given in order to introduce and conduct qualitative mitigation strategies for shaping sustainable urban environments. Results from this study could have implications for mitigation strategies at national, regional, county, and municipality levels, providing knowledge for the enhancement of geohazard prevention and appropriate response plans.

“…Landslides cause catastrophic events every year in Europe [1,2] when affecting a high number of exposed elements [3]. Landslide susceptibility (addressing only the spatial component) and hazard (analysing both spatial and temporal information), as such not targeting the risk/danger component, have been studied at various scales: at a global scale, e.g., by Nadim et al [4], NASA [5,6] and the World Bank [7]; at the European scale, e.g., by [8][9][10]; at the national scale, e.g., in France, Turkey, Pakistan, Cuba, Costa Rica and Romania by [11][12][13][14][15][16][17]. In general, susceptibility models are considered to be more suited for larger areas evaluated at regional scales than for local scales, where other methods, such as numerical modelling, are better adapted to assess related hazards [9].…”

Landslide Susceptibility Mapping in the Vrancea-Buzău Seismic Region, Southeast Romania

et al. 2021

This study presents the results of a landslide susceptibility analysis applied to the Vrancea-Buzău seismogenic region in the Carpathian Mountains, Romania. The target area is affected by a large diversity of landslide processes. Slopes are made-up of various types of rocks, climatic conditions can be classified as wet, and the area is a seismically active one. All this contributes to the observed high landslide hazard. The paper analyses the spatial component of the landslide hazard affecting the target area, the regional landslide susceptibility. First, an existing landslide inventory was completed to cover a wider area for the landslide susceptibility analysis. Second, two types of methods are applied, a purely statistical technique, based on correlations between landslide occurrence and local conditions, as well as the simplified spatial process-based Newmark Displacement analysis. Landslide susceptibility maps have been produced by applying both methods, the second one also allowing us to simulate different scenarios, based on various soil saturation rates and seismic inputs. Furthermore, landslide susceptibility was computed both for the landslide source and runout zones—the first providing information about areas where landslides are preferentially triggered and the second indicating where landslides preferentially move along the slope and accumulate. The analysis showed that any of the different methods applied produces reliable maps of landslide susceptibility. However, uncertainties were also outlined as validation is insufficient, especially in the northern area, where only a few landslides could be mapped due to the intense vegetation cover.
