Wilderness Areas Research Articles

A városszövet szukcesszió által formált zöldfelületei

The discipline of landscape architecture is witnessing a radical shift in approach. With the emergence of nature-based solutions in urban public space development, the extensive maintenance of green spaces has also come under the spotlight. The focus of this research is on the ways of establishing and expanding consciously created green spaces dominated by succession, also known as urban wilderness areas. The planning and management of these areas as a whole and of their components is still a complex task that raises many questions. In this article we define the concept of urban wilderness. In addition to the characterisation and interpretation of urban wilderness, we will also discuss its impact on the mental well-being of urban dwellers, i.e. its passive recreational aspects. The theoretical foundations explored are put into practice in a university workshop. The workshop, as an experimental laboratory, sought to answer the question of how theoretical research findings can be integrated into domestic, classical planning practice. As a result, four student concept designs were developed for a real site.

Hunted Wild Boars in Sardinia: Prevalence, Antimicrobial Resistance and Genomic Analysis of Salmonella and Yersinia enterocolitica.

The objective of this investigation was to evaluate Salmonella and Yersinia enterocolitica prevalence in wild boars hunted in Sardinia and further characterize the isolates and analyse antimicrobial resistance (AMR) patterns. In order to assess slaughtering hygiene, an evaluation of carcasses microbial contamination was also carried out. Between 2020 and 2022, samples were collected from 66 wild boars hunted during two hunting seasons from the area of two provinces in northern and central Sardinia (Italy). Samples collected included colon content samples, mesenteric lymph nodes samples and carcass surface samples. Salmonella and Y. enterocolitica detection was conducted on each sample; also, on carcass surface samples, total aerobic mesophilic count and Enterobacteriaceae count were evaluated. On Salmonella and Y. enterocolitica isolates, antimicrobial susceptibility was tested and whole genome sequencing was applied. Salmonella was identified in the colon content samples of 3/66 (4.5%) wild boars; isolates were S. enterica subs. salamae, S. ser. elomrane and S. enterica subs. enterica. Y. enterocolitica was detected from 20/66 (30.3%) wild boars: in 18/66 (27.3%) colon contents, in 3/66 (4.5%) mesenteric lymph nodes and in 3/49 (6.1%) carcass surface samples. In all, 24 Y. enterocolitica isolates were analysed and 20 different sequence types were detected, with the most common being ST860. Regarding AMR, no resistance was detected in Salmonella isolates, while expected resistance towards β-lactams (blaA gene) and streptogramin (vatF gene) was observed in Y. enterocolitica isolates (91.7% and 4.2%, respectively). The low presence of AMR is probably due to the low anthropic impact in the wild areas. Regarding the surface contamination of carcasses, values (mean ± standard deviation log10 CFU/cm2) were 2.46 ± 0.97 for ACC and 1.07 ± 1.18 for Enterobacteriaceae. The results of our study confirm that wild boars can serve as reservoirs and spreaders of Salmonella and Y. enterocolitica; the finding of Y. enterocolitica presence on carcass surface highlights how meat may become superficially contaminated, especially considering that contamination is linked to the conditions related to the hunting, handling and processing of game animals.

Reducing southern California ozone concentrations in the year 2050 under a low carbon energy scenario

Recent studies predict that ozone (O3) concentrations within major California cities in the year 2050 will continue to violate the 8-h O3 standard despite the adoption of low-carbon energy. This O3 penalty largely stems from persistent NOx-rich chemistry within urban cores that causes O3 concentrations to increase when traditional combustion sources are replaced by renewable energy sources. Here we employ a Chemical Transport Model (CTM) equipped with a novel O3 source apportionment technique to better understand O3 formation and to design supplemental control measures to complement Greenhouse Gases (GHG) reduction strategies in California. Two base scenarios were analyzed: (i) a 2050 “business-as-usual” (BAU) scenario with O3 violations on 43% of simulated days, and (ii) a 2050 Greenhouse Gases reduction (GHGAi) scenario with O3 violations on 32% of simulated days. The source apportionment results of the GHGAi scenario identified offroad equipment & rail, marine vessels & aircraft, and industrial & agricultural emissions as the major NOx sources that contributed to the O3 violations, while boundary conditions & initial conditions (BCIC) and biogenic emissions were identified as the major volatile organic compounds (VOCs) sources. Despite a HCHO/NO2 ratio (FNR) suggesting that the SoCAB is in a VOC-limited chemical regime, the major VOC sources that contribute to O3 formation are not controllable. Therefore, complementary O3 control strategies are proposed that focus on NOx emissions within the GHGAi scenario. Three cumulative Supplemental Control Steps were evaluated. Control Step I reduced emissions from off-road equipment & rail, and marine vessels & aircraft (65% NOx emissions reduction relative to GHGAi). Control Step II expanded the measures in Control Step I by reducing emissions from industrial and agricultural sources (cumulative 73.6% NOx emissions reduction relative to GHGAi), while Control Step III extended the amount of control applied to all sources covered in Control Steps I and II (cumulative 85.4% NOx emissions reduction relative to GHGAi). All three Control Steps lowered O3 concentrations significantly in the SoCAB, with residual O3 violations mainly predicted in non-populated wilderness areas. The significant reductions in O3 produced by the Supplemental Control Steps decreased the predicted incidence of hay fever/rhinitis, asthma, and all-cause mortality by an order of magnitude compared to the transformation from the BAU to GHGAi scenario. The predicted public health savings associated with the Supplemental Control Steps are valued at $19.70–30.36B/yr.

A point-in-time inventory of chikanda orchids within a wild harvesting wetland area in Mwinilunga, Zambia: implications for conservation

Despite continued wild harvesting, there is limited data that provides estimates on the availability of African edible orchids as a resource, and that identifies the ecological drivers of their dynamics. This study was designed to investigate the relationship between distance from surface water and the diversity, frequency, and population density of chikanda orchids in a harvesting wetland in Mwinilunga, Zambia. Vegetation sampling was conducted using an interrupted belt transect design. Eight 50 m transects were systematically placed and positioned perpendicular (90o) to a stream within three separate orchid communities. Individual plant count was recorded within the 0–10 m, 10–20 m, 20–30 m, 30–40 m, and 40–50 m distance zones. Results showed a statistically significant decrease in the Shannon’s Diversity Index between the distance zones in all three communities (p < 0.05). Mean ranks for orchid taxa frequency and density across the distance zones were significantly different for communities 1 and 2 but not 3 and communities 1 and 3 but not 2, respectively. However, there was a medium to large effect size for distance on frequency and a small to large effect size for distance on density in all three communities. These results suggest that distance from surface water influences the frequency and density of orchid taxa occurring in wetland ecosystems. This implies that for conservation purposes, it may be important to focus on areas close to water when establishing orchid sites for the species investigated in this study.

Different people, different wild: Comparing and mapping wilderness representation in Wuyishan National Park, China

It is essential to better integrate wilderness representations of different stakeholders into wilderness conservation. The way in which local residents and other stakeholders frame the construction of wilderness of protected areas in developing countries are poorly understood. In these areas, land use policy and decision may lead to conflicts. This study aims to explore existing public wilderness representations using a questionnaire survey (n = 514) administered amongst tourists and other stakeholders in the Wuyishan National Park, in southeast China. The spatial differences in public representations of wilderness across different stakeholder groups were compared against expert knowledge. We found that integrated wilderness representation maps of different stakeholder groups were consistent, namely ‘area where wild animals live’, ‘area with no human influence’, ‘a barren and lonely area’. However, three sub-representations of the individual stakeholders varied significantly. Moreover, expert-based wilderness mapping did not reflect public representations accurately, and an integrated wilderness quality map considering wilderness representations across both stakeholders and experts can better identify detailed wilderness areas. Our study provides new insights and technical support for future exploration of wilderness conservation and mapping in China and other countries with insufficient awareness of wilderness values and investigations in a regional scale.

African Swine Fever and Its Control Measures in Wild Boar: A "De Iure Condito" Analysis in the European Union.

Recently, the African swine fever (ASF) epizootic has been reported in domestic pigs and wild boars in several European Union Member States (EU MS) and epidemiological evidence has accumulated which indicates that wild boar play a key role in maintaining and spreading the disease. Thanks to the experience gained when managing ASF outbreaks in Sardinia (Italy) and Eastern Europe, Directive 2002/60 CE was issued. This directive represented an important step forward in controlling the disease, particularly the risk of spreading the virus to wild animals. Since 2021, according to Regulation (EU) 2016/429, which is also called "Animal Health Law-AHL", when the MS competent authority suspects or confirms ASF (a cat. A listed disease) in wild animals, it is mandatory to conduct surveillance in the wild boar population and implement the necessary control measures. Within AHL, Regulations (EU) 2020/687 and 2023/594 established special ASF control measures in kept and wild porcine animals, and their products and by-products, focusing on and underlying old and new responsibilities that vets (both public and private ones) have to accomplish under the new regulations. The new change in the legal framework deals with specific measures to be applied in the wild and represents a great challenge for MS veterinary services. Some of these measures have been well established in the last two decades, particularly those related to application in the farming system, while other measures are still new to veterinary health management and require a holistic approach in terms of intensity, considering all geographical, ecological, productive, cultural and social features of the involved EU MS. In this contribution, the authors intend to focus on specific measures which have been issued in order to limit or stop the spread of ASF in a wild, "boundless" ecosystem. These measures expand the field of competence of the official veterinary service to wild areas in addition to farm activity.

A novel species of Microsphaeropsis causing cankers on Rafnia amplexicaulis in South Africa.

Cankers leading to branch, stem and plant death were observed on the South African endemic Rafnia amplexicaulis (Fabaceae) in the Cederberg Wilderness Area, South Africa, during September 2021. Conidiomatal pycnidia were found developing on the cankers, and isolations consistently yielded a Microsphaeropsis species. Phylogenetic analysis based on partial nucleotide sequences of the internal transcribed spacers (ITS), the nuclear large subunit (LSU) and RNA polymerase II second largest subunit (RPB2) regions showed that the fungus represented an undescribed species. Based on the multigene phylogeny and morphological characteristics, we describe the species here as M. rafniae sp. nov. Pathogenicity tests and the fulfilment of Koch's postulates confirmed that M. rafniae sp. nov. is the cause of the cankers of R. amplexicaulis. Presently, this disease is known from a single location in South Africa, and further surveys are required to determine its distribution and relative importance.

Abstract The Far North region of Ontario, Canada, is a wilderness area comprising 451,808 square kilometers of intact boreal forest and wetlands. Until the work presented here the most recent extensive survey for crayfish in the Far North region of Ontario was conducted in 1963. We sampled 81 locations across the Far North region of northern Ontario and the Hudson Bay Lowlands, Canada from 2009 to 2014 catching 96 specimens from 2 species: Faxonius virilis (Hagen) (92) and Faxonius propinquus (Girard) (4) These records define the northern boundary of freshwater crayfish. Unlike much of North America, species records were consistent with surveys conducted over 55 years ago. The Far North region of Ontario is facing proposed development at a scale not seen before, and our records provide necessary baseline data for ecosystem and wildlife monitoring, understanding potential future impacts, and to support sustainable resource management.

Noncovalent binding of carbofuran to acetylcholinesterase from Homo sapiens, Danio rerio, Apis mellifera and Caenorhabditis elegans: Homology modelling, molecular docking and dynamics, and quantum biochemistry description

Although various regulatory agencies have banned or severely restricted the use of carbofuran (CAR), recent reports indicate the presence of CAR residues in both cultivated and wild areas. This pesticide is a potent inhibitor of acetylcholinesterase (AChE), which acts by preventing the hydrolysis of acetylcholine (ACh). Given the critical role of AChE::ACh in the proper functioning of the nervous system, we thought it appropriate to investigate the binding of CAR to AChEs from Homo sapiens, Danio rerio, Apis mellifera, and Caenorhabditis elegans using homology modelling, molecular docking, molecular dynamics, and quantum biochemistry. Molecular docking and dynamics results indicated peculiar structural behavior in each AChE::CAR system. Quantum biochemistry results showed similar affinities for all complexes, confirming the description of carbofuran as a broad-spectrum pesticide, and have a limited correlation with IC50 values. We found the following decreasing affinity order of AChE species: H. sapiens > A. mellifera > C. elegans > D. rerio. The computational results suggest that CAR occupies different pockets in the AChEs studied. In addition, our results showed that CAR binds to hsAChE and ceAChE in a very similar manner: it has high affinities for the same subsites in both species and forms hydrogen bonds with residues (hsTYR124 and ceTRP107) occupying homologous positions in the peripheral site. This suggests that this nematode is a potential model to evaluate the toxicity of carbamates, even though the sequence identity between them is only 41 %. Interestingly, we also observed that the catalytic histidines of drAChE and amAChE exhibited favorable contacts with carbofuran, suggesting that the non-covalent binding of carbofuran to these proteins may promote faster carbamylation rates than the binding modes to human and worm acetylcholinesterases. Our computational results provide a better understanding of the binding mechanisms in these complexes, as well as new insights into the mechanism of carbamylation.

Threats to conservation from national security interests.

There is a growing trend of nation states invoking national security and emergency declarations to build state-sponsored infrastructure projects for border defense, energy production, and transportation. Established laws, regulations, and agreements for the protection of nature and cultural heritage within and between countries are becoming secondary to national security, compromising the function of protected areas, such as national parks, wilderness areas, and biosphere reserves that safeguard biodiversity, climate, and human health. We considered cases where decades-long multinational cross-border endangered species recovery programs have been jeopardized by waivers of environmental protection laws to facilitate rapid construction of border barriers that impede the movement and migration of animals, such as at the US-Mexico and Poland-Belarus borders. Renewable energy megaprojects, such as the Pinacate solar plant in Mexico, coupled with power transmission lines and road networks likewise cast a large footprint on the land and are being carried out with minimal to no environmental compliance under the guise of national security. National sovereignty likewise has been used as justification for bypassing laws to proceed with similar projects, such as Mexico's Dos Bocas refinery and Poland's Vistula Spit canal. Emphasis on security is also apparent in increasing military expenditure by the world's largest economies, which has created a mismatch with improvement in environmental policy stringency. Decisions to prioritize security can undermine democratic principles and environmental review protocols, trivialize humanity's dependence on functioning ecosystems, and contradict the United Nation's resolution on the human right to a healthy environment. Framing infrastructure projects as matters of national security also foments civil and political unrest by the labeling and casting of dissenters, including conservation scientists and environmental defenders, as antinational. World leaders must refrain from misusing extraordinary powers, adhere to laws and international agreements, and consult experts and local people before taking unilateral action on projects that affect ecological and human communities.

From backyard to backcountry: changes in mammal communities across an urbanization gradient

Abstract Urbanization often results in biodiversity loss and homogenization, but this result is not universal and there is substantial variability in the spatiotemporal effects of urbanization on wildlife across cities and taxa. Areas with lower population and housing density are some of the fastest-growing regions in the western United States; thus, more research in these areas could offer additional insight into the effects of urbanization on wildlife and the potential importance of wild spaces in maintaining a diverse biotic community surrounding developed areas. To address this need, we conducted a study to identify the effects of urbanization (i.e. housing density) on mammals along a housing density gradient from wilderness to suburbia in Missoula, Montana. We deployed 178 motion-activated trail cameras at random sites within urban/suburban, exurban, rural, and wild regions from May to October 2019 to 2020. We identified all mammals &amp;gt;150 g, then evaluated how housing density influenced: (i) occupancy and (ii) species richness using multispecies occupancy models; (iii) relative abundance using Poisson models; and (iv) diel activity patterns using kernel density estimation and logistic regression. Urbanization was the strongest driver of mammal distribution, with a linear decline in mammal species richness as housing density increased. Urbanization also had strong effects on occupancy and detection rates, with larger-bodied mammals generally having stronger negative associations. Overall, mammal relative abundance was highest in suburban regions; however, this effect was largely driven by White-tailed Deer. Natural environmental factors explained most changes in mammal nocturnal activity; however, urbanization strongly affected nocturnality in some species, with Black Bear and White-tailed Deer becoming more nocturnal and Red Fox and Northern Raccoon becoming less nocturnal as housing density increased. While our study confirms that some mammals can live and thrive in developed areas, it emphasizes the importance of maintaining wild areas for those species that cannot.

Deer survey from drone thermal imagery using enhanced faster R-CNN based on ResNets and FPN

Deer surveys play an important role in the estimation of local ecological balance. In the Chitwan National Park of Nepal, the dense tree canopies and tall vegetation often obscure the presence of wild deer, which has a negative effect on the accurate population surveys of wild deer. UAVs equipped with infrared sensors have been increasingly used to monitor wild deer by capturing a lot of images. How to automatically recognize and obtain the number of deer objects from thermal images is becoming an important research topic. Due to the difference between thermal images and true-color images, as well as the variations in deer object sizes in these two types of images, current ready-to-use object detection models, designed for true-color imagery, are ill-suited for the task of detecting small deer objects within thermal imagery. In this paper, an enhanced Faster R-CNN was constructed to detect small deer objects from thermal images, in which a Feature Pyramid Network (FPN) based on a residual network is used to improve feature extraction for small deer objects and multi-scale feature map constrution for the subsequent region proposals searching, bounding box regression, and regions of interest (RoIs) classification. In addition, small-scaled anchor boxes and a multi-scale feature map selection criterion are devised to improve the detection accuracy of small objects. Finally, based on Faster R-CNN, FPN, and different residual networks including ResNet18, ResNet34, ResNet50, ResNet101, and ResNet152, we constructed five object detection models, and evaluated their detection performance by using COCO evaluation matrix. Under the condition of IoU≥0.5, the integration of Faster R-CNN, FPN, and ResNet18 demonstrated to perform better than others. Specifically, The COCO evaluation results revealed an Average Precision (AP) score of 91.6% for all deer objects. Small deer objects (area ≤ 200 pixels) achieved an AP score of 73.6%, medium deer objects (200 < area ≤ 400 pixels) demonstrated an AP score of 93.4%, and large deer objects (area > 400 pixels) achieved the highest AP score of 94.3%. Our research is helpful for effective wild deer monitoring and conservation and can be a valuable reference for the exploration of small object detection from low-resolution thermal images.

Sensitisation, research and management for conservation within ESPOL University forests after the COVID-19 pandemic, Ecuador

Non sustainable land uses are disturbing natural habitats and wild animals’ ecology worldwide. Nevertheless, the sensitisation of key actors combined with research and a consequent management can influence decision-making and improve animals’ well-being. COVID-19 has influenced the number of interactions with wildlife in urban environments and the ESPOL Polytechnic University is a university campus that holds forested areas in Guayaquil, Ecuador. We implemented an environmental education course with an empathetic approach for the security guards of the university. We used questionnaires to evaluate their attitudes and knowledge on wildlife before and after the sensitisation course. In addition, we registered the incidences of native fauna resulting from the guards’ collaborations and we designed management strategies according to the data gathered. The guards showed an improvement in their knowledge of the issues covered (n = 81–87; X̄ = 163.4%) and an increased preference for wild and native fauna after the sensitisation course (n = 67; 151.6%). Furthermore, the collaborations of guards with the Biodiversity Unit of the university concerning animal-human interactions increased, as did the supporting actions towards the well-being of native animals. Moreover, the information about direct and indirect interactions with wildlife included reports on traces of large to medium animal activity and a record of illegal hunting of Choloepus hoffmanni for bushmeat consumption. Obtained data sustained adaptive management actions such as signalling and restrictions in use. We recommend educating key actors with an empathetic approach, developing critical skills and promoting collaborations to reduce human impacts in wild areas.

Wilderness Paramedic—A Practice Analysis

Emergency medical services (EMS) has existed in its modern form for over 50 years. EMS has become a critical public safety net and access point to the larger health care system. Mature EMS systems are in place in most urban areas. However, EMS systems are not as developed in wilderness areas. A barrier to further development of these systems is the lack of an agreed-upon standard of minimum competence and validation of specialized practice. A practice analysis was completed to create such standards. The practice analysis was completed using a multi-step process. A group of subject matter experts constructed a survey of tasks and knowledge needed for wilderness EMS (WEMS) specialty practice. The tasks and knowledge were validated through an industry survey. A total of 947 surveys were submitted for analysis. Of these, 196 were at least 55% complete and used for analysis. North America was heavily represented as a primary practice location with 177 (90.3%) responses out of the 196 total. Of these 177 responses, 164 (92.7%) were from the United States and 12 (6.8%) were from Canada. One hundred seven of the 116 tasks identified by the subject matter expert group were passed by the survey group, and 164 of the 175 knowledge statements were passed by the survey group. An index of agreement (IOA) was calculated and found to be greater than 0.9 for each task and knowledge statement across all subgroups. A content coverage rating was also calculated and the results indicate survey participants felt the content was “adequate” to “well” covered. The survey results were used to construct a pilot examination. Beta testing of the pilot examination was performed. The beta test results were analyzed and a cut score was determined using the Angoff method with a Beuk compromise. The final product of this process is a defensible exam that will certify candidates’ cognitive knowledge of the specialty of WEMS. Completion of this practice analysis solidifies WEMS as distinct subspecialty of out-of-hospital medicine. Additionally, it establishes a consensus definition of wilderness paramedicine and standards that may be used by WEMS systems and regulatory entities.

Molecular Detection and Distribution of Giardia duodenalis and Cryptosporidium spp. Infections in Wild and Domestic Animals in Portugal

Enteric protozoan parasites Giardia duodenalis, Cryptosporidium spp., and, to a lesser extent, the ciliate Balantioides coli are responsible for severe human and animal intestinal disorders globally. However, limited information is available on the occurrence and epidemiology of these parasites in domestic, but especially wild species in Portugal. To fill this gap of knowledge, we have investigated G. duodenalis, Cryptosporidium spp., and B. coli occurrence, distribution, genetic diversity, and zoonotic potential by analyzing 756 fecal samples from several wild carnivores (n = 288), wild ungulates (n = 242), and domestic species (n = 226) collected across different areas of mainland Portugal. Overall, infection rates were 16.1% (122/756; 95% CI: 13.59–18.96) for G. duodenalis and 2.7% (20/756; CI: 1.62–4.06) for Cryptosporidium spp., while no ungulate sample analyzed yielded positive results for B. coli. Giardia duodenalis was found across a wide range of hosts and sampling areas, being most prevalent in the Iberian lynx (26.7%), the Iberian wolf (24.0%), and the domestic dog (23.9%). Cryptosporidium spp. was only identified in wild boar (8.4%), red fox (3.4%), Iberian lynx (3.3%), red deer (3.1%), and Iberian wolf (2.5%). Sequence analysis of G. duodenalis determined zoonotic assemblage A (subassemblage AI) in one roe deer sample, canine-specific assemblages C and D in Iberian wolf, red fox, and domestic dog, and ungulate-specific assemblage E in wild boar, sheep, cattle, and horse. Six Cryptosporidium species were identified: C. scrofarum in wild boar, C. canis in the Iberian wolf and red fox, C. ubiquitum in red deer and wild boar, C. felis in the Iberian lynx, and both C. ryanae and C. occultus in red deer. Giardia duodenalis and Cryptosporidium spp. coinfections were observed in 0.7% (5/756) of the samples. This is the first, most comprehensive, and largest molecular-based epidemiology study of its kind carried out in Portugal, covering a wide range of wild and domestic hosts and sampling areas. The detection of zoonotic Cryptosporidium spp. and G. duodenalis subassemblage AI demonstrates the role of wild and domestic host species in the transmission of these agents while representing a potential source of environmental contamination for other animals and humans.

Leaving traces: Fairy houses, kindness stones, and constructed heritage

AbstractThe National Park Service and many other federal, state, and local land managers in the US enjoin visitors to “leave no trace” when visiting parks and wilderness areas. At the same time, practices that involve leaving traces—painted rocks, rock cairns, and fairy houses—have become well established on some public lands. Public discussions reveal deep divides in how people view these traces in a time of increased pressures on public lands. This article develops an anthropological analysis of the practice of leaving traces at Mesa Verde National Park, in Colorado, and Machimoodus State Park, in Connecticut. Taking an approach that aligns with recent work on archaeologies of the contemporary, we interrogate the meaning of these material traces and consider how these practices of constructing cultural heritage in spaces perceived as “natural” provide a quasi‐archaeological experience and reenact colonialist processes.

Dampak Pengembangan Desa Wisata Terhadap Aspek Ekonomi, Sosial Budaya dan Lingkungan di Alamendah Kabupaten Bandung

The purpose of this study was to determine the impact of the development of a tourist village towards the aspect of economics, social culture, and physical environment in Alamendah. This study used descriptive qualitative approach. The data were collected by a researcher with direct observation, distribution of questionnaires, and interviews with the management of the Alamendah tourism village and the local community. The results showed that the development of the Alamendah tourism village had been carried out well, but in the attraction aspect there was still a lack of human resources, in terms of amenities, there was still a lack of hygiene &amp; sanitation facilities, there were no supporting facilities for tourist safety and lack of cleaning facilities. In the Accessibility aspect, there is still a lack of directions to Alamendah Tourism Village. And there is still no control on ??the Ancillary aspect. The impact on the economic aspect has a significant positive impact but the income and standard of living of the community have a slight impact and the distribution of Public Infrastructure and Facilities has an impact but not significant. The impact on socio-cultural aspect has a significant positive impact, it's just that the erosion of the local language has already been felt by the community. The impact on environmental aspects has a significant negative impact. Such as polluted water sources due to the discharge of liquid and solid waste, decreased air quality due to air pollution and also noise pollution in Alamendah Tourism Village due to exhaust emissions from each vehicle and also noise generated from busy vehicles, damage to mountain vegetation and wild areas, as well starting from the change of residential land that turned into commercial land. However, Wildlife in Alamendah Tourism Village is still well preserved.

A multispecies coexistence based on rewilding and degrowth for the sake of global health

Abstract The climate emergency is closely linked to biodiversity loss, both in its (anthropogenic) causes (anthropogenic) and possible (nature-based) solutions. Both crises are a major threat to global health because zoonoses, global warming and other climate impacts make present and future generations vulnerable, and aggravate social inequalities. Indeed, this has led some authors to start talking about ecological determinants of health. However, based on a narrative review of recent academic literature, I will argue that trophic rewilding strategies, framed within conservation biology, can ensure global health by stopping the spread of zoonoses and animating the carbon cycle. A first aim of my contribution will be to defend this correlation. Then, my next purpose will be to address how rewilding could favor coexistence with protected or reintroduced keystone species. The recent UN Biodiversity Conference (COP15) in Montreal agreed to extend the care of wilderness areas and restore 30% of degraded ecosystems by 2030, but this is a political as well as a social challenge. The current development model in Europe, based on fossil-dependent economic growth, is a stumbling block for wildlife to flourish. I will therefore argue that degrowth could be a complementary development alternative to rewilding in order to make a more serious commitment to global health. Key messages • The ecological restoration of trophic rewilding can contribute to global health by mitigating climate change and zoonoses. • The development of European societies is based on economic growth, and as this is a threat for wildlife flourishing, a shift towards degrowh could complement rewilding and strengthen global health.

Vulnerability of wilderness areas to day-use visits

SummaryProtected areas worldwide are impacted by human activities within their boundaries. Despite having the highest level of protection in the US, wilderness areas are still vulnerable to ecological impacts. We compiled population, population growth rate, median travel time, wilderness size, wilderness proximity, relative accessibility, trail density and an amenity index to generate a Day-Use Vulnerability Index (DUVI) for 722 wilderness areas in the continuous US (CONUS). Using DUVI, we found that the Mount Timpanogos wilderness area in Utah, the Glacier View wilderness area in Washington, the J.N. Ding Darling wilderness area in Florida, the Philip Burton wilderness area in California and the Birkhead Mountains wilderness area in North Carolina were most likely to have ecological impacts from high day-use. Our findings provide a system for evaluating daily use of wilderness areas that could be paired with visitor counts in the future to improve predictions. Growing human populations and recreation are worldwide issues, suggesting that this framework could also be of interest to stakeholders outside the CONUS.

Wilderness areas under threat from global redistribution of agriculture

Agriculture expansion is already the primary cause of terrestrial biodiversity loss globally1,2; yet, to meet the demands of growing human populations, production is expected to have to double by 2050.3 The challenge of achieving expansion without further detriment to the environment and biodiversity is huge and potentially compounded by climate change, which may necessitate shifting agriculture zones poleward to regions with more suitable climates,4 threatening species or areas of conservation priority.5,6,7 However, the possible future overlap between agricultural suitability and wilderness areas, increasingly recognized for significant biodiversity, cultural, and climate regulation values, has not yet been examined. Here, using high-resolution climate data, we model global present and future climate suitability for 1,708 crop varieties. We project, over the next 40 years, that 2.7 million km2 of land within wilderness will become newly suitable for agriculture, equivalent to 7% of the total wilderness area outside Antarctica. The increase in potentially cultivable land in wilderness areas is particularly acute at higher latitudes in the northern hemisphere, where 76.3% of newly suitable land is currently wilderness, equivalent to 10.2% of the total wilderness area. Our results highlight an important and previously unidentified possible consequence of the disproportionate warming known to be occurring in high northern latitudes. Because we find that, globally, 72.0% of currently cultivable land is predicted to experience a net loss in total crop diversity, agricultural expansion is a major emerging threat to wilderness. Without protection, the vital integrity of these valuable areas could be irreversibly lost.
