“…Spatial planning is still poorly addressed for NbS (Bourne et al 2016), especially in Europe (Geneletti and Zardo 2016), and the establishment of appropriate processes is critical (Albert et al 2021). Spatial planning of NbS has mostly been limited to urban areas (Brink et al 2016;Kooy et al 2020;Simperler et al 2020), coastal ecosystems (Jones et al 2020;Sutrisno et al 2021), or locally tailored initiatives (Turconi et al 2020;Zaimes et al 2020).…”

Climate change impacts mountains socio-ecosystems by increasing certain natural disasters and changing Nature's Contributions to People (NCP). Nature-based Solutions (NbS) are increasingly implemented to help local communities adapt to climatic hazards. However, the relevance of their location in relation to those hazards and local NCP has hardly been addressed. In the PORTAL project (Pathways of Transformation in the Alps), we identified and mapped a portfolio of 97 NbS for climate change adaptation in the European Alps. Most NbS addressed drought or soil instability, and aimed to provide multiple NCP simultaneously such as wood production and protective function against landslides. We analysed whether NbS are located where they are the most needed, according to both current and future intensity of the hazards they aim to address and to supply-flow-demand indicators of the NCP they aim to provide. We found that the location of NbS is overall not related to current supply-flow-demand indicators of most NCP, nor to intensity of hazards. Nevertheless, NbS addressing droughts and floods are located in areas where these hazards are more intense, but do not match higher values for NCP indicators. Conversely, NbS aiming to produce wood and to provide protective function against landslides are located in areas with greater levels of these NCP, regardless of the intensity of hazards. These results suggest that hazards and NCP indicators are not the main drivers of NbS implementation. We argue that integrating local climate conditions and current NCP flows is needed to underpin a macro-regional strategy for planning NbS implementation.

“…Post-fire vegetation monitoring with adequate VIs from satellite data, according to climate zone and vegetation type, can help planning parties to assess these effects properly and determine suitable measures. When implementing post-fire measures using soil and water bioengineering techniques to revegetate or mitigate erosion [57][58][59], the use of time series from VIs can help to understand where to place the measures, spatially, at the area in question. Knowing from experience, or from post-fire monitoring with satellite data, that, for example, the vegetation in high severity areas recovers fast, can help planning parties to decide whether to apply measures in the area or not.…”

In wildfire areas, earth observation data is used for the development of fire-severity maps or vegetation recovery to select post-fire measures for erosion control and revegetation. Appropriate vegetation indices for post-fire monitoring vary with vegetation type and climate zone. This study aimed to select the best vegetation indices for post-fire vegetation monitoring using remote sensing and classification methods for the temperate zone in southern Ecuador, as well as to analyze the vegetation’s development in different fire severity classes after a wildfire in September 2019. Random forest classification models were calculated using the fire severity classes (from the Relativized Burn Ratio—RBR) as a dependent variable and 23 multitemporal vegetation indices from 10 Sentinel-2 scenes as descriptive variables. The best vegetation indices to monitor post-fire vegetation recovery in the temperate Andes were found to be the Leaf Chlorophyll Content Index (LCCI) and the Normalized Difference Red-Edge and SWIR2 (NDRESWIR). In the first post-fire year, the vegetation had already recovered to a great extent due to vegetation types with a short life cycle (seasonal grass-species). Increasing index values correlated strongly with increasing fire severity class (fire severity class vs. median LCCI: 0.9997; fire severity class vs. median NDRESWIR: 0.9874). After one year, the vegetations’ vitality in low severity and moderate high severity appeared to be at pre-fire level.

“…The concept "cleaning-removal of alluvium" is indirectly related to the for the purpose of carrying out the settlement and anti-flood protection projects as both are being carried out works seek to remove and/or reduce the flood risk and consequently avoid it adverse effects on the natural and socio-economic environment. These cleanings should in no way be confused with forest cleanings (phytotechnical works), which are carried out by the Forestry Services following the preparation of a relevant study and whose main objective is fire protection, facilitating the access of the fire brigade vehicles in the event of a fire, but also the fulfillment of forestry purposes management in general [75,76]. x FOR PEER REVIEW 13 of 18 Furthermore, research in the database of relevant sand permissions given by the responsibility Authority (Decentralized Region of Eastern Macedonia and Thrace), resulted to zero entries concerning the specific torrent.…”

River Sand and Gravel Mining Monitoring Using Remote Sensing and UAVs

The development of methodologies for analyzing the evolution and pressures exerted on the river channel network is one of the main concerns of researchers today. The assessment of natural or artificial changes of river channels and beds plays an important role in environmental protection, but also in the implementation of integrated water resource management plans. Given the episodic and dynamic nature of river bank and bed erosion, along with the difficulty of reaching certain reaches, a methodological approach that uses aerial imagery, initially from satellite sources and afterwards from unmanned aerial vehicles, is proposed. This approach was utilized in a perennial river in Romania but also in an ephemeral torrent channel in Greece, in order to test the prevalent types of hydrographic network in the Mediterranean and Black Sea region. The methodology used was able to identify the location and the volume of the bed material extracted and the time frame in which it occurred. These encouraging results showcase an accurate but also relevantly low-cost monitoring method for illegal anthropogenic activities that can be easily adopted by the responsible authorities. The adoption of the method will contribute to the more efficient monitoring of river protection, by accurately and timely identifying areas of illegal river bed extraction that will enable authorities to enforce European Union and national legislation.
