Deep learning models for monitoring landscape changes in a UNESCO Global Geopark

By identifying Earth heritage sites, UNESCO Global Geoparks (UGGps) have promoted geo-tourism and regional economic prosperity. However, commercial and tourism development has altered the natural contexts of these geoparks, diminishing their initial value. Before implementing land use policies, spatial landscape parameters should be monitored in multiple dimensions and in real time. This study aims to develop Bilateral Segmentation Network (BiSeNet) models employing an upgraded U-structured neural network in order to monitor land use/cover changes and landscape indicators in a Vietnamese UGGp. This network has proven effective at preserving input image data and restricting the loss of spatial information in decoding data. To demonstrate the utility of deep learning, eight trained BiSeNet models were evaluated against Maximum Likelihood, Support Vector Machine, and Random Forest. The trained BSN-Nadam model (128x128), with a precision of 94% and an information loss of 0.1, can become a valuable instrument for analyzing and monitoring monthly changes in land uses/covers once tourism activities have been rapidly expanded. Three tourist routes and 41 locations in the Dak Nong UGGp were monitored for 30 years using three landscape indices: Disjunct Core Area Density (DCAD), Total Edge Contrast Index (TECI), Shannon's Diversity Index (SHDI), based on the results of the model. As a result, 18 identified geo-sites in the Daknong Geopark have been influenced significantly by agricultural and tourist activities since 2010, making these sites less uniform and unsustainable management. It promptly alerts UNESCO management to the deterioration of geological sites caused by urbanization and tourist development.

Alternate Edens: History, Evolution, and Origins in UNESCO's Cultural and Scientific History of Mankind

In 1963, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) published the first volume of its long-awaited cultural and scientific history of mankind. First announced in 1948, the History of Mankind was envisioned as a comprehensive, universal human history, from the evolution of Homo sapiens to the middle of the twentieth century. This article uses editorial conflicts over the site of the cradle of the human species to explore the position of scientific knowledge in world history writing and to examine tensions between different national traditions of expertise at a moment of political and scientific transition.

International guidelines for the prevention of sexual violence: A systematic review and perspective of WHO, UN Women, UNESCO, and UNICEF's publications

BACKGROUND

Sexual violence is a major public health issue worldwide, with a high prevalence and extensive human and financial costs. Implementing prevention programs is complex, requiring not only evidence-based practices and high ethical standards, but also close collaboration with local governments and non-governmental organizations. In order to guide and support all stakeholders necessary to achieve large-scale prevention (e.g., politicians, decision-makers, in-field professionals), it is essential to establish international benchmarks for the prevention of sexual violence.

OBJECTIVE

The main goal of this collaborative study was to conduct a systematic review of the frameworks adopted by WHO, UN Women, UNESCO, and UNICEF to help prevent sexual violence worldwide, according to the PRISMA methodology. A secondary objective was to highlight the levels of prevention and determinants of health targeted by these organizations.

RESULTS

Overall, 1008 references were identified, of which 50 met the inclusion criteria. All international guidelines were limited to primary or tertiary prevention, and they were not specifically dedicated to sexual violence. In addition, each organization had developed idiosyncratic prevention strategies. Common primary prevention determinants of health were still found across organizations, including education, socio-economic inequalities, and life skills training. Tertiary prevention was poorly developed and polarized between victims and perpetrators. Secondary prevention was never addressed, however, despite the effectiveness of approaches such as helplines for people sexually attracted to children.

DISCUSSION

Given these results, an international French-speaking consortium of professional teams, all involved in the secondary prevention of sexual violence, was recently formed with a ratified charter presented here.

Conservation spillover effect of UNESCO World Heritage Sites into surrounding landscapes

Protected areas (PA) are one of the primary tools for conserving and protecting biodiversity, but their goals have evolved overtime beyond nature conservation to include supporting human communities within and adjacent to the PA. UNESCO World Heritage Sites (WHS) offer a unique perspective on the success of PAs as they fall under three categories, cultural, natural, and mixed heritage sites. The nature of these categories encapsulates the inclusion of human communities in the goals of the WHS. To understand the impact and relationship the WHS has with its surrounding landscape, we assessed changes in three indicators, land use and land cover (LULC), human footprint (HF), and forest landscape integrity index (FLII), across three spatial scales, 1, 10, 100 km from the WHS boundary. We found that there is a conservation spillover effect at least within 1 km of the WHS boundary. In this buffer zone, HF was low and FLII was high. FLII was lower and HF was higher at larger spatial scales. The relationship between the WHS and its surrounding landscape is one reason to support the WHS network, however, management of PAs should be more explicit about this relationship as well as relationships between individual PAs.

Decolonizing Botany: Indonesia, UNESCO, and the Making of a Global Science

Decolonization created new opportunities for international scientific research collaboration. In Indonesia this began in the late 1940s, as Indonesian scientists and officials sought to remake the formerly colonial botanical gardens in the city of Bogor into an international research center. Indonesia sponsored the Flora Malesiana project, a flora of all of island Southeast Asia. This project was formally centered in Bogor, Indonesia, with participation from tropical botanists from around the world. The international orientation of Indonesian science led to the establishment of one of UNESCO's Field Science Co-operation Offices in Jakarta, and to a period of close collaboration between Indonesian botanists and UNESCO. This paper examines the importance of UNESCO's Humid Tropics research program, which initially provided further opportunities for Indonesian botanists to participate in international scientific networks. The paper concludes by showing that the Humid Tropics program led to the slow erosion of Indonesian agency and authority over tropical botany, and the assertion of Western control and management over tropical botany research.

Gold mining impairs the biological water quality of a culturally important river and UNESCO World Heritage Site in Nigeria

The UNESCO World Heritage Sites have special conservation regulations because they are recognized as having significant cultural and/or natural value. One of Nigeria's two UNESCO-designated World Heritage Sites is the Osun River. It has immense biodiversity values, which are currently being threatened due to gold mining activities within its catchment area. Thus, this study seeks to ascertain the current biological water quality of this culturally and internationally important river using ecological and ecotoxicological approaches. Samples were collected from three environmental compartments (i.e., water, benthic sediment, and macroinvertebrates) in both dry and wet seasons from the section of the river that flows through the UNESCO site. Findings revealed that the river's physiochemical water quality has immensely degraded on account of extremely high total suspended solids, extremely low water transparency, and low dissolved oxygen. Three heavy metals exceeded their permissible limits in drinking water; i.e., Cd (364-367 times higher), Pb (75-104 times higher), and As (35-67 times higher). The contamination factor indicated that the benthic sediments were contaminated with Cd and Au, while the geo-accumulation (Igeo) index only indicates contamination on account of Cd, though Au ranks second in order of Igeo. The composition of the river's macroinvertebrate fauna suggests that it has been severely impacted because there was almost no stress-sensitive Ephemeroptera-Plecoptera-Trichoptera taxon present (one taxon and one individual only). Almost all of the chosen heavy metals had bioaccumulated in the three functional feeding guilds of macroinvertebrates. The current levels of heavy metals in the three environmental compartments of the river pose a great risk to both freshwater biodiversity and human health. Thus, a re-channeling of the upstream effluents from the river or any other natural water is advised. Also, a periodic environmental audit of the river should be conducted until it recovers from the pollution stress.

Classification of the Effort Index and Biomechanical Overload in Natural Trails of UNESCO Global Geoparks-A Network Perspective of Trails of the Araripe UGG (NE Brazil)

Natural trails in UNESCO Global Geopark territories show strong salutogenic, inclusive and interactive characteristics as potentials and opportunities for ecosystem health. It is essential to provide information to inform the hiker as to the characteristics of the environment and the attractions and challenges of the route. Based on a network analysis methodology we aimed to identify the indicators of centrality and strength of connection in order to classify the effort index and biomechanical overload of the Araripe UNESCO Global Geopark trails in Brazil. The results showed strong connection and centrality of the variables related to the biomechanical overload in the effort index. In the trail of Pontal de Cruz the altimetric variation and the surface of the ground are highlighted in the biomechanical overload that presented a horizontal course equivalent 2.6 times larger than the presented distance. In Sítio Fundão trail, the surface of the ground also stood out, increasing the exposure in 36% of the presented distance. On the Missão Velha Waterfall trail, the variable that stood out was the biomechanical overload on the knee, equivalent to a horizontal increase of 28% of the measured distance. The methodology presented sought to optimise the mapping, management and consolidation of a network of natural trails aggregated to a high geotouristic, scientific, educational, cultural and well-being potential as presented in the Araripe UGG territory.

BREMi-A New Tool for the Evaluation of UNESCO Biosphere Reserve Management Effectiveness: Case-study in the Arab Man and Biosphere (ArabMAB) Regional Network

Scholars and practitioners have been striving to develop straightforward and effective tools to measure protected area management effectiveness (PAME). UNESCO Biosphere Reserves (BR), with their unique functional and zonation schemes are monitored according to their compulsory 10-year Periodic Review (PR), which is useful for UNESCO's evaluation purposes but lacks comprehensiveness and utility for adaptive management. Based on existing PAME methodologies, we develop and propose the first quantitative tool for the evaluation of BR management effectiveness, that would enhance and complement the currently used qualitative PR report, and serve the rapid evaluation needed for BR managers to monitor, evaluate, and adapt their management approach to achieve the three functions of BRs. The tool consists of 65 indicators, embodied within the 6 elements of the World Commission on Protected Areas Framework. We then tested this tool, named Biosphere Reserve Effectiveness of Management index (BREMi) to evaluate management effectiveness across the Arab Man and the Biosphere Reserve network involving 17 BRs spanning 8 countries of the Middle East and North Africa. BREMi scores ranged from 4.43 to 8.65 (on a scale between 0 and 10), with a mean of 6.31 ± 1.040. All indicators were considered valuable measures of progress by our respondents, as well as by independent experts. We discuss our findings in light of available literature concerning the Arab region and through the conceptual frames of adaptive management and resilience. Finally, we discuss where the BREMi tool would be most useful for BR management authorities in the iterative process of evaluation and adaptive management.

Analysis of UNESCO ESD Priority Areas' Implementation in Romanian HEIs

Higher education institutions (HEIs) are adopting sustainable development (SD) in their strategies for the future. The roadmap by UNESCO is the path to follow to reach success. The approach is different for every HEI, thus the objective of this paper is to analyze the current state of education for sustainable development activities provided by HEIs through the eyes of the academic community (responders category: professors, researchers, associate professors). The method to conduct the study was an interview that had 40 enclosed questions and a free part at the end where the responders could bring additional information to the study if they considered it necessary. All the interviews were transcribed and given a code (e.g., RHEI1, RHEI 29) in order to perform the analysis using descriptive statistics with the help of the program MS Office EXCEL. The results showed some areas where the activities provided by HEIs need improvement and also revealed promising aspects through partnerships. Making the values of SD known to the academic and local community will help fulfill the true potential for change and future development. Moreover, the analysis showed the need to educate educators and improve their digital skills and teaching methods/techniques in order to achieve sustainable development. Another result revealed the need for improvements in HEI curricula that will contribute to gaining those skills/abilities that emerging jobs should have.

Study on the rare waterbird habitat networks of a new UNESCO World Natural Heritage site based on scenario simulation

As a newly established World Natural Heritage site, the conservation of rare waterbird habitats in the Yancheng coastal wetlands has attracted wide international attention. In view of the importance of this area in international biodiversity conservation and waterbird habitat conservation, the study of the current situation of rare waterbird habitat networks with spatial isolation features of great demonstration significance to improve the habitat conservation quality of the heritage site. Based on the data obtained from habitat suitability assessments of rare waterbirds, this paper used complex network theory, ecological stepping-stone theory and circuit models to analyze the current status and robustness of rare waterbird habitat networks in the Yancheng coastal wetlands. The results showed that the stepping stones of the red-crowned cranes and the Oriental storks were mainly distributed around important habitat areas, including aquaculture ponds and reed marshes, with areas of 1275.68 hm² and 1247.74 hm², respectively, while the stepping stones of Saunders's gulls were mainly distributed within the Tiaozini habitat site, with an area of 1180.76 hm². The stability and connectivity of the habitat networks of red-crowned cranes and Oriental storks in the northern habitat area were better. At the Tiaozini habitat site, there was spatial isolation and low connectivity among the habitats and stepping stones of Saunders's gulls. In the optimal protection scenario, the stability and connectivity of the habitat network structure of red-crowned cranes and Oriental storks were the best, and the networks tended to exhibit assortativity. In the random destruction scenario, the connectivity of the habitat networks of Saunders's gulls was the lowest, and the network structure was the most fragile. Finally, the optimization and restoration patterns of habitat network based on improving the support capacity of important habitat nodes and the enhancement of the stability and connectivity of the stepping-stone networks were proposed.

UNESCO biosphere reserves show demand for multifunctional agriculture

Sustainable landscape management of protected areas in UNESCO-biosphere reserves (BR) has become an increasingly important topic for academics and environmental practitioners, yet it remains unclear how this can be operationalized in actual regional circumstances. To achieve positive and measurable sustainability impacts, effective BR management on the ground requires supplementary methods to conceive the unique territorial, political, economic and social characteristics of each case while also considering the needs and visions of different stakeholder groups. In this study, we used the Framework for Participatory Impact Assessment (FoPIA) to assess future projections of current land management strategies and possible alternatives in five BR in Germany. The FoPIA method helped identify major differences in the regional BR contexts, including defining the sustainability problem and sustainability challenges. It also proved suitable for fostering stakeholder dialog with regard to current and future sustainable land use management, particularly for the BR transition zones. Our results predict multiple negative impacts resulting from of a continuation of current practices, which are compared against the assessed outcomes of alternative multifunctional pathways. We use these findings to discuss recommendations and challenges for sustainable management of biosphere reserves, the potential of implementing the FoPIA in BR, and perspectives for further research needs.

A puzzling marriage? UNESCO and the Madrid Festival of Science (1955)

From 17 to 22 October 1955, Madrid hosted the UNESCO Festival of Science. In the early years of the Cold War, in a dictatorial country that had recently been admitted into the international community, the festival aimed to spread science to the public through displays of scientific instruments, public lectures, book exhibitions, science writers professional associations, and debates about the use of different media. In this context, foreign visitors, many of whom came from liberal democracies, seemed comfortable in the capital of a country ruled by a dictatorship that had survived after the defeat of fascism in the Second World War and was struggling to gain foreign recognition after years of isolation.This article analyzes the political role of science popularization in Madrid at that time. It approaches the apparently puzzling marriage between UNESCO's international agenda for peace and democracy and the interests of the Francoist elites. Shared views of technocratic modernity, the fight against communism, and a diplomacy that served Spanish nationalism, paved the way for the alliance.

Fire risk management in Tabriz Historic Bazaar Complex as a UNESCO World Heritage Site: 2009-2019 experiences

Tabriz Historic Bazaar Complex (THBC) is one of the historical monuments of Iran. It has been registered in the list of The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites. However, the destructive power and frequency of fires are the main threat to this bazaar. This research examined the factors affecting the fire in THBC and the key components affecting the fire risk management based on the 2009-2019 experiences. The obtained findings showed that 25 components in economic, physical, socio-cultural, technical, and managerial dimensions were effective in the occurrence of fire in this bazaar. There were many fires during national-religious ceremonies. The highest rate of fire in leather shops was during carpet sales. Also, the highest rate of fire was from 22 to 3 at midnight, especially in winter. The results also showed that out of 26 components affecting fire risk management, 10 components were vital factors, the most important of which were modern equipment, control of electrical equipment, and night guards and activity monitoring. Finally, according to the obtained results, practical suggestions were offered to focus on modern equipment and the use of patrol forces.

Reviewing the participatory management of UNESCO Biosphere Reserves: What do we miss by ignoring local academic knowledge in Mexico?

This review article addresses challenges in the management of UNESCO Biosphere Reserves (BRs) by analyzing the value of research published in journals, chapters, and books that are not indexed by Web of Science or Scopus. This widely ignored body of grounded knowledge allows deeper insights when assessing participatory management of BRs, an imperative reflected in guiding principles such as Aichi Target 11. The scoping literature review conducted found 120 publications that address stakeholder participation in decision-making and the economic benefits generated in Mexican BRs. Only 65 of those studies were published in indexed journals, while national outlets accounted for the other 55, most of them also peer-reviewed publications. International papers differ from national ones regarding spatial coverage, research foci, and the methods applied. Though both bodies of publications identified similar challenges, each sheds a distinct light on social-environmental contexts and regions. However, there is a consensus that genuine stakeholder participation has not yet been achieved.

Quantifying the impacts of non-carbonic acid (NCA) stress on dissolved inorganic carbon (DIC) generation in the granitic-hosted watershed, Huangshan UNESCO Global Geopark, China

To better understand the impacts of non-carbonic acid (NCAs, including sulfuric, nitric and organic acids) stress on DIC generation during chemical weathering, this study investigated the water chemistry and stable isotope composition (δ¹³C_DIC) from a granitic-hosted watershed at Huangshan UNESCO Global Geopark, China. The results show that the dissolved loads of the watershed are dominated by both silicate and carbonate weathering. As a region with greatly distributed acid soil and high occurrence of acid rain, the evolution of the dissolved loads and δ¹³C_DIC show that DIC generation in carbonate dissolution is promoted by H₂SO₄, reduced by HNO₃ and little disturbed by organic acids. The reduction is due to CO₂ release in carbonate weathering by strong nitric acid formed by nitrification in acid soil. New participating proportions of NCAs in rock weathering yielded by the multiple linear regressions between major ions, DIC and δ¹³C_DIC are introduced into calculations of DIC yields. The overestimated DIC yields by silicate and carbonate weathering by NCAs account for about 34% of total DIC yields calculated with the assumption that all carbonates and silicates are dissolved by H₂CO₃ alone during a year. The results imply that the modifications of DIC generation by NCAs, especially HNO₃ formed in acidic silicate soil, could consequently partly counterbalance the natural CO₂ sink in the granitic-host region.

Introducing Petrachlorosaceae fam. nov., Petrachloros gen. nov. and Petrachloros mirabilis sp. nov. (Synechococcales, Cyanobacteria) Isolated from a Portuguese UNESCO monument

The Synechococcales is a large cyanobacterial order comprising both unicellular and filamentous forms, with parietal thylakoid arrangement. Previously, this order has been the subject of taxonomic revisions with new families being erected. During studies of the phototrophic communities on the limestone walls of the Old Cathedral of Coimbra (UNESCO monument), a coccoid Aphanocapsa-like cyanobacterium was isolated. It was characterized using a polyphasic approach, based on morphology, 16S rRNA phylogenetic and phylogenomic analyses, internal transcribed spacer (ITS) secondary structure, and ecology. The 16S rRNA phylogenetic analyses showed that this strain is placed in a separate and highly supported family-level clade, as part of a large group comprising the families Prochlorococcaceae and Prochlorotrichaceae, with Lagosinema as the closest (although quite distant) taxon. Additionally, the phylogenomic analysis also placed this strain in a separate lineage, situated distantly apart from the family Thermosynechococcaceae, but with strains assigned to Acaryochloris marina MBIC 11017 and Aphanocapsa montana BDHKU210001 as the closest taxa. Based on these data, as well as on the results from the secondary ITS structure, morphology, and ecology, we here propose the establishment of Petrachlorosaceae fam. nov., along with the description of Petrachloros gen. nov. and Petrachloros mirabilis sp. nov. We also address additional considerations regarding some cyanobacterial taxa within the order Synechococcales, which we believe deserve further revisions.

A Qualitative Assessment of Community Learning Initiatives for Environmental Awareness and Behaviour Change: Applying UNESCO Education for Sustainable Development (ESD) Framework

This study uses qualitative research methods of text mining to elucidate the potential and prospects for community-based learning opportunities for raising environmental awareness and bringing about healthy behaviour change among university students and local residents. In particular, we focus on the importance of community-based learning in raising environmental awareness and inspiring action to support healthy living and harmony with nature. The three groups were triangulated using semi-structured questionnaires to model the ways in which education for sustainable development (ESD) can contribute to the promotion of environmental education in local communities. In order to collect in-depth data, the authors themselves were present at the study sites and collected textual data based on semi-structured questionnaires in a participatory observation framework, where they had a common experience to understand the observations. Analysis was carried out using NVivo12. The two community learning initiatives studied were in Okayama and Tokyo, which are leading ESD policy areas. The two case studies are both university student-led projects that aim to raise environmental awareness in local communities through environmentally conscious behaviour change and the creation of a foundation for healthy living. This study focuses on "youth" and "community" among the five priority areas proposed in the 2015 ESD report and discusses the potential and prospects for community learning initiatives and the triggering of the nudge effect on environmentally conscious behaviour change and health behaviours. The results of the textual analysis with triangulation show that, while policymakers and teachers and leaders driving the initiative acknowledge the importance of ESD in a comprehensive way, their attention is more focused on the design of specific projects and curricula. In contrast, university students engaged in ESD activities rated the social education facilities (local community centres, community learning centres) as "lively" and "motivating". It was found that there are high expectations for "public living rooms", which are important as a base for learning to promote healthy and sustainable communities and environmentally conscious behaviour change.

From surviving to thriving, the assembly processes of microbial communities in stone biodeterioration: A case study of the West Lake UNESCO World Heritage area in China

Serious concerns regarding stone biodeterioration have been raised due to the loss of aesthetic value and hidden dangers in stone cultural heritages and buildings. Stone biodeterioration involves a complex ecological interplay among organisms, however, the ecological mechanisms (deterministic or stochastic processes) that determine the microbial community on stone remain poorly understood. Here, using both amplicon and shotgun metagenomic sequencing approaches, we comprehensively investigated the biodiversity, assembly, and function of communities (including prokaryotes, fungi, microfauna, and plants) on various types of deteriorating limestone across different habitats in Feilaifeng. By generalizing classic ecological models to stone habitats, we further uncovered and quantified the mechanisms underlying microbial community assembly processes and microbial interactions within the biodeteriorated limestone. Community profiling revealed stable ecosystem functional potential despite high taxonomic variation across different biodeterioration types, suggesting non-random community assembly. Increased niche differentiation occurred in prokaryotes and fungi but not in microfauna and plant during biodeterioration. Certain microbial groups such as nitrifying archaea and bacteria showed wider niche breadth and likely contributing to the initiation, succession and expansion of stone biodeterioration. Consistently, prokaryotes were more strongly structured by selection-based deterministic processes, while micro-eukaryotes were more influenced by dispersal and drift-based stochastic processes. Importantly, microbial coexistence maintains network robustness within stone microbiotas, highlighting mutual cooperation among functional microorganisms. These results provide new insights into microbial community assembly mechanisms in stone ecosystems and may aid in the sustainable conservation of stone materials of interest.

Linguistic diversity and conservation opportunities at UNESCO World Heritage Sites in Africa

Africa contains much of Earth's biological and cultural-linguistic diversity, but conserving this diversity is enormously challenging amid widespread poverty, expanding development, social unrest, and rapidly growing human population. We examined UNESCO (United Nations Educational, Scientific and Cultural Organization) Natural World Heritage Sites (WHSs) on continental Africa and nearby islands-48 protected areas containing globally important natural or combined natural and cultural resources-to gauge the potential for enlisting Indigenous peoples in their conservation. We used geographic information system technology to identify instances where Natural WHSs co-occur with Indigenous languages, a key indicator of cultural diversity. And, we compared the geographic ranges for 4 taxa and selected freshwater species with occurrence of all Indigenous languages within Natural WHSs and subsections of WHSs covered by the geographic extent of Indigenous languages to measure the correlation between linguistic and biological diversity. Results indicated that 147 languages shared at least part of their geographic extent with Natural WHSs. Instances of co-occurrence where a WHS, a language, or both were endangered marked localities particularly deserving conservation attention. We examined co-occurrence of all languages and all species, all languages and endangered species, and endangered languages and endangered species and found a correlation between linguistic and biological diversity that may indicate fundamental links between these very different measures of diversity. Considering only endangered species or endangered languages and species reduced that correlation, although considerable co-occurrence persisted. Shared governance of government-designated reserves is applicable for natural WHSs because it capitalizes on the apparent connection between culture and nature. Natural WHSs in Africa containing speakers of Indigenous languages present opportunities to conserve both nature and culture in highly visible settings where maintaining natural systems may rely on functioning Indigenous cultural systems and vice versa.

Arsenic concentrations, distributions and bioaccessibilities at a UNESCO World Heritage Site (Devon Great Consols, Cornwall and West Devon Mining Landscape)

Devon Great Consols (DGC) is a region in south west England where extensive mining for Cu, Sn and As took place in the nineteenth century. Because of its historical and geological significance, DGC has protected status and is part of the Cornwall and West Devon Mining Landscape UNESCO World Heritage Site. Recently, the region was opened up to the public with the construction or redevelopment of various trails, tracks and facilities for walking, cycling and field visits. We used portable x-ray fluorescence spectrometry to measure, in situ, the concentrations of As in soils and dusts in areas that are accessible to the public. Concentrations ranged from about 140 to 75,000 μg g^-1 (n = 98), and in all but one case exceeded a Category 4 Screening Level for park-type soil of 179 μg g^-1. Samples returned to the laboratory and fractionated to <63 μm were subjected to an in vitro assessment of both oral and inhalable bioaccessibility, with concentrations ranging from <10 to 25,500 μg g^-1 and dependent on the precise nature and origin of the sample and the physiological fluid applied. Concentrations of As in PM₁₀ collected along various transects of the region averaged over 30 ng m^-3 compared with a typical concentration in UK air of <1 ng m^-3. Calculations using default EPA and CLEA estimates and that factor in for bioaccessibility suggest a 6-h visit to the region results in exposure to As well in excess of that of minimum risk. The overall risk is exacerbated for frequent visitors to the region and for workers employed at the site. Based on our observations, we recommend that the remodelling or repurposing of historical mine sites require more stringent management and mitigation measures.

Biotransport of persistent organic pollutants in the southern Hemisphere by invasive Chinook salmon (Oncorhynchus tshawytscha) in the rivers of northern Chilean Patagonia, a UNESCO biosphere reserve

Biotransport is often associated with migration patterns of species, including large, anadromous salmonids. Several studies have reported biotransport of persistent organic pollutants in the Northern Hemisphere, but there is no published information on biotransport ocurring south of the equator. Chile's Patagonia is one of the last largely intact natural areas in the world. The objective of this study was to determine whether persistent organic pollutants are transported by the invasive Pacific Chinook salmon (O. tshawytscha) from the Pacific Ocean to Chilean Patagonia. Samples of juvenile and adult Chinook salmon were analyzed for polychlorinated biphenyls, pesticides and polybrominated diphenyl ethers. The results revealed that concentrations of POPs in adults migrating into Patagonian rivers were significantly higher than those found in juveniles migrating seaward. A mass balance analysis indicates that Chinook salmon are a source of persistent organic pollutants to Chilean Patagonia inland waters. Capsule: Biotransport of Persistent Organic Pollutants (POPs) by Chinook salmon (O. tshawytscha) from the Pacific Ocean to Chilean Patagonia has been confirmed by mass balance of POPs.

Crushing the curve, the role of national and international institutions and policy makers in COVID-19 pandemic

Nobody can be fully prepared to a pandemic. Of course there are signs of it, the scientists can predict, alarming speeches can be made. But there are always alarmist people around, maybe that is why sometimes even the most serious warnings may be not considered by the authorities on time. The first patients may be lost without a proper diagnosis. When everybody realizes that there may be a big problem in the horizon, sometimes it is too late. That is why it is very important to monitor contagious diseases and follow the warnings and releases of national and international disease control centers and other related organizations. China celebrated Lunar New Year with more than 40 thousand families on the 18 of January 2020. Nobody seem to be expecting this emerging new viral pneumonia outbreak appeared in Wuhan, in the last days of 2019, will break the chains and turn out to be a pandemic! But maybe this time it was not too late. There were four important pandemics within the last century: Spanish Flu, Hong Kong Flu, Asian Flu and Swine Flu. Each left different story behind. Millions of people had infected, hundreds, thousands of people died. This time, the Modern World had different tools to limit the SARS CoV2 outbreak. The national and international institutions of our globe were all communicating and taking precautions in a very fast manner than ever. However, this time, unexpectedly, the SARS-CoV-2 contagion was also faster. Besides the international organizations like WHO, UNESCO and UNICEF, the roles of local authorities, health ministries, disease control centers, health protection agencies, research centers and universities are all very important in different operational levels to control and survive from the pandemic. This paper will review the immediate response of different national and international institutions and authorities to COVID-19 pandemic.

Waste into rivers: a residual issue? The case of the UNESCO's site of the Quebrada De Humahuaca, NW Argentina

The Quebrada de Humahuaca in North West Argentina is a world heritage site listed by the UNESCO since 2003. As pollution is increasing dramatically, a pluridisciplinary, annual-long survey was conducted along the valley to determine dominant patterns in waste management and water quality. Along with the habit of discarding waste into the river, urbanizations have been identified as having a deep influence on the river water quality: iron together with maximum peaks of nitrite and nitrate are related with the anthropogenic activity at Humahuaca, whereas the concentrations of arsenic increase from north to south, with maximum peaks of up to 13.50 and 14.50 μg L^-1 measured during the rainy season at Maimará and Volcán, respectively. In this underdeveloped region, economic struggles and waste management customs revealed as major factors causing the environmental degradation. The inclusion in the UNESCO's sites list was insufficient in preserving this world heritage site. The approach discussed in this article suggests a straightforward analytical measurement of the river hydrochemical properties during the rainy season in arid/semi-arid regions with monsoonal regime, to assess the effects of waste dumping along watercourses. In addition to scientific evaluations, both public acceptance and the establishment of proper waste management infrastructure are fundamental to ensuring the preservation of human and environmental health.

[The UNESCO brand in the prosecco hills: opportunity or new health risk?]

The historical hill-site zone of Prosecco's wine production was recognised as a UNESCO World Heritage Site. This area is part of the province of Treviso, an area where in recent years many lands have been occupied by the viticulture to produce this type of wine, due to a growing demand of prosecco, especially on international markets. Currently viticulture occupies 31% of the total agricultural area of the province. This is determining an important alteration of the landscape of the area, with serious loss of biodiversity. Even more, this intensive cultivation requires the use of many pesticides (in 2018, 4,622 tons were sold, equivalent to more than 36 kg per hectare of arable land), that are harmful to the health of the population. They can cause acute effects by inhalation or contact during the treatment of the vines, and chronic effects for the continuous intake of small doses through contaminated waters. To safeguard the environment and health, two actions are needed: to reduce the use of pesticides by promoting organic production; to restore biodiversity by promoting other crops besides the vineyards. Our hope is that belonging to the UNESCO heritage world list favours these actions.

The UNESCO national biosphere reserve (Marismas del Odiel, SW Spain): an area of 18,875 ha affected by mining waste

At the mouth of the Odiel River, within the Natural Area "Marismas del Odiel", there has been for years a collection of waste from different mining sites. In the present work, an approach has been made to the problem that this supposes, quantifying the pollutants that are poured into the estuary from the mineral collection located on the banks of the river. The study carried out has been able to determine high metal concentrations, comparable with any rubble from the upstream mines, with pH value of 1.66, lower than many other areas affected by acid mine drainage in the same river, and even with concentrations of Fe and As higher than those provided by the rest of the mining facilities of the Odiel basin. This can make us understand the serious situation of the Natural Park, where a great variety of birds and plants of special ecological interest are located.

Is UNESCO's Undergraduate Bioethics Integrated Curriculum (Medical) fit for purpose?

In 2017, UNESCO introduced an Undergraduate Bioethics Integrated Curriculum to be taught in Indian medical schools, with an implied suggestion that it could subsequently be rolled out to medical schools in UNESCO's other member states. Its stated aim is to create ethical awareness from an early stage of a doctor's training by infusing ethics instructions throughout the entire undergraduate medical syllabus. There are advantages to a standardised integrated curriculum where none existed. However, the curriculum as presently drafted risks failing to achieve its laudable aims. There are important lessons to be drawn from UNESCO's First Syllabus for Youth Bioethics Education (2018), which is aimed at schoolchildren and teenagers, and represents a creative, effective and culturally sensitive way to teach bioethics.

The sources and biogeochemical cycling of carbon in the Wudalianchi UNESCO Geopark volcanic system in Northeast China

The biogeochemical cycling and response mechanisms of carbon within the Wudalianchi UNESCO Global Geopark were characterized by the isotopic compositions of dissolved inorganic carbon (δ¹³C_DIC) and dissolved organic carbon in ground and surface (lake) waters and their relating carbon isotopic composition of soil (δ¹³C_SOC) and sediment organic carbon (δ¹³C_org). In addition to mantle-derived CO₂, the oxidation of organic matter was prevalent in shallow groundwater during the summer. Their associated degassing of CO₂ produced higher pCO₂ values than in autumn or winter and elevated δ¹³C_DIC values. In summer, DIC in the epilimnion showed a wide range of δ¹³C_DIC from - 8.4 to 2.6‰. Waters in open-lake areas with relatively positive δ¹³C_DIC values and the low levels of pCO₂ were primarily influenced by CO₂ degassing. Photosynthesis elevated the δ¹³C_DIC values and led to minimal pCO₂ levels in closed lake areas. Isotopically, δ¹³C_org was found to be positively related to δ¹³C_SOC. In addition, lake bed sediments generally had lower concentrations and larger δ¹³C values of organic carbon than the surrounding soils. These results suggest that ¹²CO₂ derived from the degradation of sediment was preferentially utilized by phytoplankton in the epilimnion during photosynthesis. The remaining ¹³C-rich organic matter was retained in the sediment. Since 2000, δ¹³C_org increased in lake 3 over time, reflecting the input of sewage and land use changes associated with a resort used for tourism. The values of δ¹³C_org in lake 5, distant from the resort, did not change substantially, indicating minimal human impacts.

[Complexity, law and science: Reflections on the UNESCO Recommendation on the status and responsibility of the scientific researcher]

The analysis of the complexity and interactivity in the production of social norms between science and technology, on the one hand, and between law and ethics, on the other hand, must be our first concern because without a lucid and in deep assessment of the fragmented and even opposed realities that make up our world, not only do we lose all forms of collective freedom but above all we favor reductive totalitarianism and warlike confrontation.It is with this in mind that it is necessary to examine whether the revision of the 1974 Recommendation on the Status and Responsibility of the Scientific Researcher is likely to provide relevant elements for responding to these changes.
