Tracing climate and land-use instability reveals new insights into the future of Earth’s remaining wilderness

Accelerated loss of Earth’s wilderness over the last five decades underscores the urgency for efforts to retain the conservation value of these areas. Assessing how wilderness areas are likely to be impacted by the future environmental change is fundamental to achieving global biodiversity conservation goals. Using scenarios of climate and land-use change during baseline (1970–2005) and future (2015–2050) epochs, we found that climate change within wilderness areas is predicted to increase by ~ 47%, compared to a 19% increase in land-use change. Half (52%) of all wilderness areas may undergo climate change by 2050, limiting their capacity to shelter biodiversity. More significant changes are especially predicted to occur in the unprotected wilderness that supports unique assemblages of species and are therefore more important for biodiversity persistence. Countries with smaller and disconnected wilderness areas are disproportionately at risk from the combined impacts of climate and land-use change. Mitigating greenhouse gas emissions and preserving remaining intact natural ecosystems can help fortify these frontiers of biodiversity.

Rock magnetic and micro-morphological analysis on snow deposits: recognition of anthropogenic origin of particulate matter in urban and wilderness areas (central Italy)

Low field magnetic susceptibility and other rock magnetic analyses are applied to inspect the magnetic nature of solid residuals in snow samples collected in downtown Rome and in two Natural Parks in central Italy. Field emission scanning electron microscope and energy dispersive spectroscopy (FESEM-EDS) analyses are utilized to reveal the nature of Fe-rich particles and discriminate their anthropogenic origin. The results indicate that magnetite (Fe3O4) is the main magnetic carrier in almost all samples and that the variations in concentration are directly associated with local sources of particulate matter (PM) from anthropogenic pollution related to automotive circulation in both environments. Magnetic minerals of other provenance are found as accessories. The snow deposits revealed to be an efficient neutral tool for fine particle collections, also in environments characterized by different concentration and source of pollutants.

The COVID-19 Pandemic and the Environment in the Asia Pacific

The COVID-19 pandemic has exposed the consequences of political and ecological choices that have been made and continue to be made in the Asia Pacific. Over recent decades, the region’s rapid urbanization and industrialization have played a significant role in dynamic national economic development, a rapid rise in per capita income and the establishment of some of the world’s fastest-growing cities. Development has, however, come at a heavy price: planetary-health experts believe that a byproduct of human intrusion into remote wilderness areas has been a sharp uptick in environmental degradation and zoonotic diseases such COVID-19. Moreover, people living with poor air quality are more susceptible to this virus, and airborne particulate matter may even help to spread the virus. A study conducted by the Harvard University T.H. Chan School of Public Health has confirmed that there is a statistical correlation between high levels of air pollution and increased Covid-19 mortality rates.

Detecting Archaeological Features with Airborne Laser Scanning in the Alpine Tundra of Sápmi, Northern Finland

Open access airborne laser scanning (ALS) data have been available in Finland for over a decade and have been actively applied by the Finnish archaeologists in that time. The low resolution of this laser scanning 2008–2019 dataset (0.5 points/m2), however, has hindered its usability for archaeological prospection. In the summer of 2020, the situation changed markedly, when the Finnish National Land Survey started a new countrywide ALS survey with a higher resolution of 5 points/m2. In this paper we present the first results of applying this newly available ALS material for archaeological studies. Finnish LIDARK consortium has initiated the development of semi-automated approaches for visualizing, detecting, and analyzing archaeological features with this new dataset. Our first case studies are situated in the Alpine tundra environment of Sápmi in northern Finland, and the assessed archaeological features range from prehistoric sites to indigenous Sámi reindeer herding features and Second Word War-era German military structures. Already the initial analyses of the new ALS-5p data show their huge potential for locating, mapping, and assessing archaeological material. These results also suggest an imminent burst in the number of known archaeological sites, especially in the poorly accessible and little studied northern wilderness areas, when more data become available.

Research priorities for control of zoonoses in South Africa

Background Zoonoses pose major threats to the health of humans, domestic animals and wildlife, as seen in the COVID-19 pandemic. Zoonoses are the commonest source of emerging human infections and inter-species transmission is facilitated by anthropogenic factors such as encroachment and destruction of wilderness areas, wildlife trafficking and climate change. South Africa was selected for a ‘One Health’ study to identify research priorities for control of zoonoses due to its complex disease burden and an overstretched health system. Methods A multidisciplinary group of 18 experts identified priority zoonotic diseases, knowledge gaps and proposed research priorities for the next 5 y. Each priority was scored using predefined criteria by another group of five experts and then weighted by a reference group (n=28) and the 18 experts. Results Seventeen diseases were mentioned with the top five being rabies (14/18), TB (13/18), brucellosis (11/18), Rift Valley fever (9/11) and cysticercosis (6/18). In total, 97 specific research priorities were listed, with the majority on basic epidemiological research (n=57), such as measuring the burden of various zoonoses (n=24), followed by 20 on development of new interventions. The highest research priority score was for improving existing interventions (0.77/1.0), followed by health policy and systems research (0.72/1.0). Conclusion Future zoonotic research should improve understanding of zoonotic burden and risk factors and new interventions in public health. People with limited rural services, immunocompromised, in informal settlements and high-risk occupations, should be the highest research priority.

Spatial and temporal variability of ozone along the Colorado Front Range occurring over 2 days with contrasting wind flow

Transport of pollution into pristine wilderness areas is of concern for both federal and state agencies. Assessing such transport in complex terrain is a challenge when relying solely on data from standard federal or state air quality monitoring networks because of the sparsity of network monitors beyond urban areas. During the Front Range air quality study, conducted in the summer of 2008 in the vicinity of Denver, CO, research-grade surface air quality data, vertical wind profiles and mixing heights obtained by radar wind profilers, and ozone profile data obtained by an airborne ozone differential absorption lidar augmented the local regulatory monitoring networks. Measurements from this study were taken on 2 successive days at the end of July 2008. On the first day, the prevailing winds were downslope westerly, advecting pollution to the east of the Front Range metropolitan areas. On this day, chemistry measurements at the mountain and foothills surface stations showed seasonal background ozone levels of approximately 55–68 ppbv (nmol mol–1 by volume). The next day, upslope winds prevailed, advecting pollution from the Plains into the Rocky Mountains and across the Continental Divide. Mountain stations measured ozone values greater than 90 ppbv, comparable to, or greater than, nearby urban measurements. The measurements show the progression of the ozone-enriched air into the mountains and tie the westward intrusion into high-elevation mountain sites to the growth of the afternoon boundary layer. Thus, under deep upslope flow conditions, ozone-enriched air can be advected into wilderness areas of the Rocky Mountains. Our findings highlight a process that is likely to be an important ozone transport mechanism in mountainous terrain adjacent to ozone source areas when the right circumstances come together, namely a deep layer of light winds toward a mountain barrier coincident with a deep regional boundary layer.

Tranquillity mapping in New Zealand national parks – a pilot study

The tranquillity in national parks worldwide is currently under threat from intrusion of anthropogenic noise of a growing tourism industry and activity related to park management. This was addressed by creating informative tranquillity maps, where perceived tranquillity can be considered a key indicator of soundscape quality in natural areas. Tranquillity of an area can be assessed using TRAPT (Tranquillity Rating Prediction Tool), that has been developed and refined for assessing urban green spaces, national parks and wilderness areas in the United Kingdom. The subjective response to helicopter noise levels of a sample group of 35 people representing the general New Zealand population was obtained, based on visual and audio stimuli that were collected in Aoraki/Mt Cook National Park. These results were used to produce a revised TRAPT equation. It was discovered that levels under 32 dBA correspond to an excellent level of tranquillity. This threshold was used to produce a noise level exposure calculation for two national parks using noise prediction model AEDT (Aviation Environmental Development Tool). Contours representing tranquillity duration were then calculated and plotted, to serve as a planning tool for use by the Department of Conservation. A similar approach could be used for other national parks worldwide.

Nature Interpretation and Visitor Management Objectives: A Survey of Tourist Attitudes at Maasai Mara National Reserve, Kenya

Nature interpretation has been advocated as a soft and non-obtrusive on-site visitor management strategy to enhance visitor knowledge and understanding of the resource, mitigate visitor impacts, encourage the conservation and improvement of attraction areas, and assist visitors in enjoying their visit. However, the way in which nature interpretation programs are implemented, and the subsequent attitudes created amongst visitors can pose a challenge to the effectiveness of nature interpretation as a visitor management strategy. The situation becomes more complicated with limited resources to implement, monitor, and evaluate nature interpretation in expansive wilderness areas like Masai Mara National Reserve (MMNR). The question therefore is, does nature interpretation in MMNR create favourable attitudes amongst wildlife tourists, consequently leading to enhanced visitor experiences and satisfaction of the support for conservations, or not? This research, therefore, sought to establish the extent to which the attitudes created by nature interpretation affect visitor satisfaction or the enhanced visitor experience and support for conservation, broadly termed as visitor management objectives in MMNR Kenya. Thus, Ho1 postulated that attitudes created by nature interpretation do not influence visitors’ support for conservation in MMNR, and Ho2, that attitudes created by nature interpretation do not enhance visitor experience and satisfaction in MMNR. This study used a structured questionnaire for the survey to collect data from a sample of 351 respondents as a proportion of visitors into MMNR. Research findings revealed that a moderate relationship between attitudes created by nature interpretation and support to conservation with rs = 0.426 and p = 0.000, thus null hypothesis H01 was rejected. Secondly, results showed that attitudes created by nature interpretation moderately affected visitor satisfaction rs = 0.478 and p = 0.000, while similarly, null hypothesis H02 was rejected. The research concluded that various forms of NI result in the formation of attitudes that moderately affect support for conservation and visitor satisfaction. The study concluded that enhanced nature interpretation training and awareness creation, along with continual improvement initiatives, could unlock its full potential as a visitor management strategy. This consistent, well-coordinated, and diligent implementation of nature interpretation initiatives by all stakeholders in MMNR would sustain a cumulative, long-term impact.
