Evaluating the impact of wildland fires on landscapes, a pursuit increasingly supported by remote sensing techniques, requires an understanding of wildfire dynamics. This research highlights the main insights from the literature related to “wildfires” and “remote sensing” published between 1991 and 2020. The Scopus database was used as a source of information regarding scientific production on these topics, after which bibliometric tools were employed as a means through which to reveal patterns in this network of journals, terms, countries, and authors. The results suggest that these subject areas have undergone significant developments in the last three decades, having been the focus of growing interest among the scientific community. The most relevant contributions to the literature available have been made by researchers working in the areas of earth and environmental sciences (54% of the publications), primarily in the United States, China, Spain, and Canada. Research trends in this field have undergone a significant evolution in recent decades, explained by the strong relationship between the technological evolution of detection methods and remote sensing data acquisition.

Remotely sensed land surface temperature (LST) enables global modelling and monitoring carbon dioxide (CO2) fluxes from peatlands. We aimed to provide the first overview of the LST potential for monitoring ecosystem respiration (Reco) in disturbed (drained and extracted) peatlands. We used chamber measured data (2017–2020) from five disturbed and two intact northern peatlands and LST data from Landsat 7, 8, and MODIS missions. First, we studied the strength of relationships between fluxes and their in-situ drivers: thermal and moisture conditions. Second, we examined the association between LST and in-situ temperatures. Third, we compared chamber measured Reco with the modelled Reco based on (i) in-situ measured surface temperature and (ii) MODIS LST. In-situ temperatures were a stronger driver of CO2 fluxes in disturbed sites (Spearman correlation R=0.8–0.9) than in intact ones (R=0.5–0.7). LST had a higher association with in-situ measured temperatures (mean R=0.74 for MODIS) in disturbed sites and weaker in the intact peatlands (mean R=0.34 for Landsat and 0.36 for MODIS). Reco models driven by MODIS LST and in-situ surface temperature yielded similar accuracy: R-squared was 0.26, 0.64, 0.65 and 0.28, 0.68, 0.58 for intact, drained and extracted sites, correspondingly. Therefore, LST has a great potential to be utilized in Reco models as a proxy of thermal regime in disturbed and intact northern peatlands.

The river habitat survey (RHS) system is a method used to assess the physical features and quality of rivers, which was developed to assist in the conservation and recovery of riverside habitats. The RHS takes into account the need to characterize areas of intervention from a hydromorphological point of view, in order to introduce corrective measures aimed at restoring degraded sections and habitats, and increasing local biodiversity. In this paper, we present the results obtained from the application of the RHS methodology to the River Selho, in the municipality of Guimarães (Portugal). The transects that we defined were strongly influenced by anthropic actions that have modified the riverside habitats, the artificialization of the river channel, and the urban occupation of the banks. Taking into account the results, we can point out the main problems that currently affect the hydromorphological quality of the transects analyzed in the River Selho, as well as identify the originating factors: the excessive silting of the watercourse; morphometric changes, with an emphasis on the narrowing and modification of the channel and the banks; as well as the massive destruction of the riparian zone. This study shows that the application of the RHS methodology is a useful tool for the management of degraded riverside areas.

Besides water table depth, soil temperature is one of the main drivers of greenhouse gas (GHG) emissions in intact and managed peatlands. In this work, we evaluate the performance of remotely sensed land surface temperature (LST) as a proxy of greenhouse gas emissions in intact, drained and extracted peatlands. For this, we used chamber-measured carbon dioxide (CO2) and methane (CH4) data from seven peatlands in Estonia collected during vegetation season in 2017–2020. Additionally, we used temperature and water table depth data measured in situ. We studied relationships between CO2, CH4, in-situ parameters and remotely sensed LST from Landsat 7 and 8, and MODIS Terra. Results of our study suggest that LST has stronger relationships with surface and soil temperature as well as with ecosystem respiration (Reco) over drained and extracted sites than over intact ones. Over the extracted cites the correlation between Reco CO2 and LST is 0.7, and over the drained sites correlation is 0.5. In natural sites, we revealed a moderate positive relationship between LST and CO2 emitted in hollows (correlation is 0.6) while it is weak in hummocks (correlation is 0.3). Our study contributes to the better understanding of relationships between greenhouse gas emissions and their remotely sensed proxies over peatlands with different management status and enables better spatial assessment of GHG emissions in drainage affected northern temperate peatlands.

Social media continues to grow, permanently capturing our digital footprint in the form of texts, photographs, and videos, thereby reflecting our daily lives. Therefore, recent studies are increasingly recognising passively crowdsourced geotagged photographs retrieved from location-based social media as suitable data for quantitative mapping and assessment of cultural ecosystem service (CES) flow. In this study, we attempt to improve CES mapping from geotagged photographs by combining natural language processing, i.e., topic modelling and automated machine learning classification. Our study focuses on three main groups of CESs that are abundant in outdoor social media data: landscape watching, active outdoor recreation, and wildlife watching. Moreover, by means of a comparative viewshed analysis, we compare the geographic information system- and remote sensing-based landscape organisation metrics related to landscape coherence and colour harmony. We observed the spatial distribution of CESs in Estonia and confirmed that colour harmony indices are more strongly associated with landscape watching and outdoor recreation, while landscape coherence is more associated with wildlife watching. Both CES use and values of landscape organisation indices are land cover-specific. The suggested methodology can significantly improve the state-of-the-art with regard to CES mapping from geotagged photographs, and it is therefore particularly relevant for monitoring landscape sustainability.

Integrated use of citizen science (crowdsourcing in general) and remote sensing is essential to comprehend the complexity of the notion of landscape, based on subjective experience and objective structure of environment. Organisation-related landscape attributes, such as landscape diversity and orderliness, as well as the extent of colour harmony, greenness, and transport accessibility, were recently recognised as indicators for visual and recreational values of environment. However, it is currently an open research question, whether mentioned anthropocentric nature-related values are dependable on these landscape attributes, quantifiable with GIS and remote sensing, and accurate mapping of aesthetic and recreational landscape services is important to answer this question. Image hosting services and social networks provide a huge source of evidence on the aesthetic and recreational landscape experience, allowing for mapping the intangible anthropocentric values with publicly shared georeferenced photographs. Therefore, we aimed to apply automated image recognition with Clarifai service to assign each photograph with tags, reflecting its content, and further topic modelling (a variety of textual analysis) to group the tags into the categories.
In this study, we used combined Flickr and VK.com dataset for 2016-2018 years, collected via official APIs within the territory or Estonia; outdoor photographs were grouped into three classes: aesthetic landscape experience, outdoor recreation activities and wildlife watching. Non-relevant photographs and photographs with repeating content from the same author were excluded from analysis; a dataset of >10000 photographs was finally analysed. Cloud-free summertime Landsat-8 mosaic for 2018 was used to estimate the landscape diversity, orderliness, colour harmony extent, greenness and other metrics, whereas digital elevation model and land use/land cover model were used to map landscape coherence, terrain ruggedness, and indicate transport accessibility. Contrary to previous findings, users of Flickr and VK.com tend to take photographs of lower landscape diversity and lower greenness. We confirm that, according to the photographs being studied, water presence, terrain ruggedness, and transport accessibility are the best indicators of recreational experience. Colour harmony of land cover and landscape coherence are moderately higher for actual outdoor photographs.
Performance of the mentioned indicators varies among the groups of photographs, wildlife watching is the least predictable class of recreational landscape services. The applicability of remote sensing-based mapping of landscape attributes and textual analysis of tags, extracted for outdoor photographs, is examined and discussed. Our results contribute to the deeper understanding of landscape pattern and processes, responsible for visual and recreational values, as well as the methodology is based on the integrated quantitative approach, supporting evidence-based landscape science and decision-making.

Over the last decades, the different issues regarding the expansion of the wildland-urban interface (WUI) - particularly those related to fires - have spread around the world with particular exposure in the USA, Canada, Australia, and, more recently, in southern European countries (e.g. Portugal and Greece). It has been receiving even more attention from the scientific community particularly due to the ecological and sociological implications on the management of natural resources and decisions associated with spatial planning. Consequently, throughout the extensive research conducted on wildfires, there has been a growing interest and body of literature on wildfires in the WUI worldwide. Although there are many articles published in English, in indexed journals, there is an excellent body of literature published in other languages (e.g. French, Spanish, Portuguese), which is not very well known and rarely cited. In this body of literature, whether in English or other languages, concepts and definitions are not always consensual. In this sense, this paper aims at reviewing the key concepts regarding intrinsic characteristics of the WUI and wildfires in the WUI, presenting evaluation methodologies that have been applied to WUI and analyzing several risk prevention and reduction programs developed in WUI affected by forest fires in different parts of the world. Through our analysis we found that the work developed by researchers worldwide on this subject is significant, considering the increasing relevance of this environmental problem. However, it is fundamental to define standardized methodologies in order to facilitate the transfer of knowledge and promote cooperation, interdisciplinarity. The implementation of a collaborative approach is needed, especially in the development of strategies to prevent and reduce fire risk in these areas.

A Serra da Penha localiza-se no município de Guimarães, atingindo os 613 metros de altitude e incluindo uma área verde de 50 hectares que, devido às suas características naturais, constitui um dos grandes pontos de atração turística municipal. No contexto das estratégias ambientais que têm vindo a desenvolver, a Câmara Municipal de Guimarães está a elaborar a classificação da Serra da Penha como Paisagem Protegida Local, proposta esta que deve ser entendida como uma medida de proteção e de valorização. Entre os valores naturais da Serra da Penha destacamos os valores geomorfológicos e geológicos, definidos como geossítios no Plano Diretor Municipal de Guimarães. A Serra da Penha apresenta um elevado valor e interesse geológico devido à sua natureza granítica, integrando também um conjunto diversificado de elementos geomorfológicos, com destaque para os grandes blocos dispersos nas vertentes (as penhas) e que podem vir a constituir um importante geopatrimónio a valorizar. A diversidade destes elementos é significativa, podendo-se encontrar blocos graníticos associados em formas diversificadas, com um arranjo particular, com configurações antropomórficas ou associados a determinados aspetos culturais e/ou religiosos, como seja o “penedo que abana”, o “penedo suspenso” ou a gruta do ermitão. Assim, procuramos analisar a relevância dos valores geomorfológicos no âmbito do Geopatrimónio e seu enquadramento no processo de candidatura da Serra da Penha como Paisagem Protegida Local.

Previous research in environmental psychology and landscape science has demonstrated that the complexity (based on diversity) of the visual landscape positively influences landscape values and public preferences through a relationship with landscape coherence. In this study, we suggest one possible GIS-based indicator of landscape coherence calculated for a digital landscape model (DLM). It measures the degree to which the visual landscape as a whole exceeds the set of its overlapping components (landforms and land cover) regarding diversity. We verified the performance of the index within the National Park Peneda-Gerês (Northern Portugal) as a study area with cumulative viewsheds based on Flickr and Panoramio geolocated content. The results demonstrate a scale-dependent, positive relationship between the proposed index of landscape coherence for the categorical models and the landscape values. The findings of this study can be applied to landscape planning and management, providing an easy-to-use GIS-based indicator of landscape character assessment.

In 1939, Carl Troll pointed out that “air photo interpretation is to a large extent landscape ecology”. From that time forward, remote sensing has been applied across different disciplines to comprehend the holistic and dynamic spatial layout of the visual Earth environment. However, its applicability in the domain of landscape character assessment, landscape design and planning is still questionable. The purpose of this paper was to synthesise some historical and current applications of remote sensing for the decomposition of the continual visual landscape from a bird’s eye perspective and to explore the potential for bridging geographic processes with visual perception and an appreciation of the landscape pattern. From the point of view of landscape ecology, the organisation of the landscape pattern [namely, the size, shape (form), number, density and diversity, the complexity of landscape elements, and colours and textures of the land cover] is crucial for the cognition of both the visual landscape experience and the geographic processes. There are numerous pieces of evidence from the literature that remote sensing data are widely implemented in the modelling of physiognomic landscape. The synthesis of the literature concludes with perspective directions of remote sensing applications, such as mapping the status of the ecosystem (landscape) services provision, the delineation of the boundaries of the protected areas based on the quality of the visual environment, and the assessment of the sustainability of the land use practices, regarding their impact on landscape aesthetics extent.

According to data from the Forests and Nature Conservation Institute (ICNF), the potential land suitability in Portugal for forest use is estimated to be about 59.4% (5.3 million hectares). However, according to the 6th National Forest Inventory, published in 2010, the effective area occupied by forests is only 35.4%. In the present work, we analyze the evolution of land use in mainland Portugal since the last quarter of the twentieth century, with a particular focus on forest areas.

The concept of colour harmony, being rarely used in geography, landscape and environmental studies, has been significantly developed in psychology, art and computer science within the different approaches: colour wheel geometry and, more recently, numerical models applied to colour combinations. Using the main numerical principles of colour harmony, borrowed from the psychological literature, this study aims to investigate the ways of mapping the extent of the colour harmony of land cover, based on satellite Earth observations and explain the spatial distribution of colour harmony scores. The naturalness of environment, as well as heat and moisture balance, are confirmed to be the main drivers of the colour harmony of land cover. Crowdsourced photographs, collected from Mapillary service, were used to link satellite and ground-based estimations of the colour harmony of land cover as “proof of concept”. They have a limited applicability for ground-based assessment of scenic colour harmony. Therefore, remote sensing data provide a significant support for nature conservation and sustainable management, being used for mapping of the colour harmony of land cover as an indicator of the visual quality of the perceived environment.
