Tourism is a key driver of regional economies, but concerns are often raised about the effectiveness with which public resources are managed and translated into tangible outcomes. Despite its importance, research on the efficiency of public spending on tourism remains scarce and mostly confined to national scales. Therefore, this study examines how Apulian municipalities (Italy) convert public tourism expenditure into measurable tourism results, providing new evidence on the efficiency of local governance in this sector. The analysis applies a two-step econometric framework combining Stochastic Frontier Analysis (SFA) and Multiple Linear Regression to data from 247 municipalities over the period from 2020 to 2023. The results reveal generally low average efficiency levels, with only a few coastal destinations achieving high performance. The regression analysis identified key structural and territorial drivers of efficiency, including accommodation capacity, cultural production, coastal and environmental quality, and the presence of agritourism and campsites. The findings suggest that efficiency depends more on the ability of local administrations to coordinate tourism, cultural, and environmental policies than on the amount of spending. Overall, the study provides empirical evidence that an efficient allocation of tourism funds is crucial for achieving long-term sustainability goals, offering practical insights for designing more effective tourism policies.

This paper delves into the process of evangelization undertaken by the Spanish in the northern frontier of New Spain during the 16th century, specifically targeting the nomadic Indigenous populations known as Chichimecas. Missionaries encountered unique challenges due to the absence of religious infrastructure, robust political authorities, and the nomadic lifestyle of these groups. To overcome these hurdles, the Spanish implemented a strategy that intertwined evangelization with colonization. The text highlights the significance of constructing physical infrastructure in these frontier territories, such as churches, schools, and dwellings, to facilitate the process of evangelization and colonial control. Moreover, it emphasizes the need to impose a social and political structure on these nomadic communities, transforming them into obedient colonial subjects. Full article

In recent years, many community-based conservancies (CBCs) led by non-governmental organizations (NGOs) have been established on land inhabited by pastoralists in Northern Kenya. Despite a growing body of research, little attention has been paid to the impacts on pastoralists’ climate change adaptation. We provide a deeper understanding by considering NGO-led community-based conservation (NGO-led CBC) as a new frontier of territorialization and adaptation to climate change and variability as a social-natural process. Based on an analysis of primary data collected in Samburu County, Kenya, we show that NGO-led CBC involves resource enclosures that aggravate conflicts over land rights and pastoralists’ vulnerability to climate change and variability by constraining their mobility. In relation, the legal and institutional environment promoted by NGO-led CBC leads to increased control over ecologically vibrant lands, which erodes pastoralists’ land tenure security and climate change adaptation. Although NGO-led CBC plays an important role in enhancing access to external finance and incentivizing diversification, governance mechanisms remain opaque and overshadow local institutions. Overall, we highlight the need for actors to carefully consider the implications of this conservation/development model for already hard-pressed land-dependent communities. Full article

Brazil has emerged as the world’s largest soybean producer and exporter in recent years. In the Brazilian Amazon Biome, the state of Pará has become a new agricultural frontier over the last two decades due to a significant increase in soybean cultivation throughout its territory. However, it is essential to understand the associated effects on the environment at every point in the supply chain. This research aims to measure the effects on the environment of the soybean supply chain of two production poles utilising openLCA software and the life cycle assessment (LCA) methodology in the northeast (Paragominas) and south (Redenção) of the state of Pará in Brazil. In addition, we determine which is the most efficient route between the shipment port and the ultimate destination. The Recipe Midpoint (H) and Intergovernmental Panel on Climate Change (IPCC) methods of environmental impact categories were used in accordance with the cradle-to-grave scope. The BRLUC regionalised model (v1.3) was used to quantify land use change (LUC). According to the observed results, LUC was primarily responsible (between 3.8 and 32.69 tCO₂ Eq·ha⁻¹·year⁻¹) for the global warming potential (GWP) of the soybean supply chain when rainforest-occupied land was converted into cropland. The soybean harvest in the Redenção pole is better loaded through the port of Itaqui (TEGRAM), which is in São Luis (state of Maranhão), due to the use of multiple modes of transport (lorry + train), allowing for better logistical performance and less impact on the environment, despite the longest distance (road + railway = 1306 km). Due to the short road distance (approximately 350 km) and consequently lower environmental impact, soybean harvested in the Paragominas pole is better loaded through the ports around Barcarena in the state of Pará.

Bioprospecting of novel antibiotics has been the conventional norm of research fostered by researchers worldwide to combat drug resistance. With the exhaustion of incessant leads, the search for new chemical entities moves into uncharted territories such as the deep sea. The deep sea is a furthermost ecosystem with much untapped biodiversity thriving under extreme conditions. Accordingly, it also encompasses a vast pool of ancient natural products. Actinobacteria are frequently regarded as the bacteria of research interest due to their inherent antibiotic-producing capabilities. These interesting groups of bacteria occupy diverse ecological habitats including a multitude of different deep-sea habitats. In this review, we provide a recent update on the novel species and compounds of actinomycetes from the deep-sea environments within a period of 2016–2022. Within this period, a total of 24 new species of actinomycetes were discovered and characterized as well as 101 new compounds of various biological activities. The microbial communities of various deep-sea ecosystems are the emerging frontiers of bioprospecting. Full article

With growing demands of decision making in the current era, the impact of the drivers behind individuals’ preferences and institutional strategies becomes prominent. Coined in 2008, nudge is used to describe incentives for individuals’ choices with foreseeable outcomes but without exclusion of alternative choices or reliance on financial stimuli. Consequently, nudge and its application in real-world situations led to a prosperous surge of studies in multiple disciplines. However, we are still facing a dearth of in-depth understanding of the status quo and future directions of research on nudge in a comprehensive fashion. To address the gap in knowledge, the present study adopted a bibliometric analysis of the existing literature related to the investigation and application of nudge by analyzing 1706 publications retrieved from Web of Science. The results indicated that (a) being a relatively newly developed theory, interest in nudge in academia has expanded both in volume and disciplines, with Western scholars and behavioral economists as the backbones; (b) future studies in nudge-related fields are expected to consolidate its current frontiers in individual behaviors while shedding light on new territories such as the digitalized environment. By incorporating state-of-the-art technologies to investigate extant research, the present study would be pivotal for the holistic understanding of the studies on nudge in recent years. Nevertheless, the inclusiveness and comprehensiveness of the review were limited by the size of the selected literature. Full article

To understand the research trends and areas of focus of seed dispersal, a bibliometric study based on the Science Citation Index Expanded (SCI-E) and Social Science Citation Index (SSCI) databases of the Web of Science Core Collection (WoSCC) was performed. With the help of CiteSpace visualization software, a systematic analysis was carried out on 2911 publications from various countries in the field of seed dispersal. The activity index (AI) and attraction index (AAI) were used to evaluate the research effort and academic impact of different countries/territories in this field, and the global research progress and dynamic changes in research on seed dispersal were discussed. The number of publications on seed dispersal has increased rapidly since 1990, and research on seed dispersal is in the growth stage and has great potential. Ecology was the journal with the highest impact in this field, and ecology was the most popular subject category among the studies analyzed. The most productive authors in the field of seed dispersal are from Spain, and the most productive institution is in the USA. A keyword burst analysis showed that the new research frontiers were mainly concentrated on seed body size and the ecological network of seed dispersal. An in-depth analysis of seed dispersal research indicated that the increasing development of mathematical models related to seed dispersal creates an opportunity to study the processes of seed dispersal and their consequences.

The adoption and ratification of new conventions and treaties under international law designed to protect both Indigenous peoples and the rights of nature have resulted in successful rulings by local, federal, and regional courts in favor of Indigenous groups engaged in class-action suits against their governments. In 2012 and 2019, respectively, the Sarayaku Kichwa and the Huaorani and Cofán peoples of the Ecuadorian Amazon won cases against the Ecuadorian government for its lack of consultation on planned oil exploration. Such cases upholding the correct application of the right to Free, Prior, and Informed Consent (FPIC) under international treaties are rare; more often, Western judicial systems and environmental impact assessments have been used to serve corporate interests, as exemplified by the Aguinda v. Texaco case initiated in 1993 and the planned operations of Andes Petroleum in Orellana province 2019–2020, respectively. Indigenous and non-Western epistemologies tend to be incompatible with state-driven liberal secular capitalism—hence Indigenous efforts to prevent land seizures and the expansion of the extractive frontier into Indigenous territories in the Amazon rainforest have been undermined by the imperatives of modernization/developmentalism. These same forces have stimulated demand for gold, the legal and illegal mining of which, along the Napo river, have caused the contamination of the waters of the Amazon, threatening the health of Indigenous and non-indigenous riverine communities.

Currently, a significant portion (~50%) of global warming emissions, such as CO₂, are related to energy production and transportation. As most energy usage will be electrical (as well as transportation), the efficient management of electrical power is thus central to achieve the XXI century climatic goals. Ultra-wide bandgap (UWBG) semiconductors are at the very frontier of electronics for energy management or energy electronics. A new generation of UWBG semiconductors will open new territories for higher power rated power electronics and solar-blind deeper ultraviolet optoelectronics. Gallium oxide—Ga₂O₃ (4.5–4.9 eV), has recently emerged pushing the limits set by more conventional WBG (~3 eV) materials, such as SiC and GaN, as well as for transparent conducting oxides (TCO), such asIn₂O₃, ZnO and SnO₂, to name a few. Indeed, Ga₂O₃ as the first oxide used as a semiconductor for power electronics, has sparked an interest in oxide semiconductors to be investigated (oxides represent the largest family of UWBG). Among these new power electronic materials, Al_xGa_1-xO₃ may provide high-power heterostructure electronic and photonic devices at bandgaps far beyond all materials available today (~8 eV) or ZnGa₂O₄ (~5 eV), enabling spinel bipolar energy electronics for the first time ever. Here, we review the state-of-the-art and prospects of some ultra-wide bandgap oxide semiconductor arising technologies as promising innovative material solutions towards a sustainable zero emission society.

Independent art spaces not only play an important role in exploring frontiers in the visual arts but are often also pioneers discovering new artistic territories within cities. Due to their subordinate position in the field of art, they often occupy marginal spaces in terms of their location within the urban structure and/or in terms of their physical visibility within the built environment. Their location outside the established artistic cores reflects, at the same time, their weaker economic standing and wish to distinguish themselves from previous generations of cultural producers. Post-socialist cities offer the opportunity to study the spatial history of independent art spaces under different political and economic systems. In this paper, I have used a detailed database of private art galleries in the period from the 1970s to 2019 and content analysis of press and internet texts about them to uncover the stages of development of independent art venues in Krakow, Poland, an example of a post-socialist city with a rich cultural heritage. They included periods of dispersion within the wider inner-city followed by cycles of concentration in rather neglected quarters that were emerging as epicentres of alternative artistic life only to dissipate due to unfavourable economic conditions and the appearance of the next generations of artists who wanted to mark their distinctive presence both in the art world and in the urban space. I also discuss how independent art spaces were using their usually marginal, temporary and fluid sites in their artistic practices and the accumulation of symbolic capital in the field of art.

Biomass is seen as one of the most dominant future renewable energy sources. In detail, agro-industrial by-products represent a cheap, renewable, and abundant feedstock useful for several new products, including biochemical, biomaterials, and above all biogas, which are taking on an ever-increasing role in Italy. In this context, the tomato chain was analysed aiming at estimating the amount of processed tomato and the related waste production as a new suitable resource for producing biofuel as a new frontier within the context of a circular economy. Due the importance of the tomato industry, this research aims at filling gaps in the knowledge of the production and yield of the by-products that are useful as biomass for energy use in those territorial areas where the biomethane sector is still developing. This aim could be relevant for planning the sustainable development of the biomethane sector by reducing both soil consumption for dedicated energy crops and GHG emissions coming from the biomass logistic supply. The achieved results show the localization of territorial areas highly characterized by this kind of biomass. Therefore, it would be desirable that the future policies of development in the biomethane sector consider the availability and the distribution of these suitable biomasses within the territory.

Due to the necessity of developing renewable energy sources, the anaerobic digestion for producing biomethane has developed significantly in the last years, since it allows to both reduce disposal treatment and produce green energy. In this field, fruit and vegetable wastes have been recently put forward, since they could represent a suitable resource for producing biomethane as a new frontier within the context of a circular economy. This study aims at filling the gap in the knowledge of the production, quantities and biogas potential production of these residues. On this basis, a GIS-based model was developed and applied to the Sicily region by investigating the specific regulatory framework as well as by analysing descriptive statistics. The results of the GIS analyses enabled the localisation of the highest productive territorial areas and highlighted where fruit and vegetable wastes are abundantly located. In this regard, about 7 million Nm³ of biogas could be produced by reusing only the fruit and vegetable residues coming from the three most representative Sicilian wholesale markets among those considered. Finally, the regulatory framework is of crucial importance in inhibiting or supporting the use of the selected biomass in a specific sector, with regard to the case study considered. Full article

Tourism explores new frontiers by traveling around unknown geographical and technological territories that bring new tourism opportunities and hazards to satisfy visitors’ needs and sustainability and responsibility in destinations. This study introduces a composite model for measuring travel motivation and the impact of social media on travel behavior and applies it to the town of Longyearbyen in the High Arctic. Both aspects were surveyed through qualitative semi-structured visitor interviews. While the motivation to visit Longyearbyen depended on travelers’ needs, their travel experiences, and push and pull motivational factors, respondents gave examples of how social media positively or negatively affected different elements of their motivation and visitation. The study indicates the opportunities and hazards analyzed from social media as well as future research directions needed in the pursuit of a more responsible tourism approach while exploring new technological and geographical frontiers.

Highly cited papers in the Essential Science Indicators database refer to papers with citations in the top 1% of all papers in a research field, and they are considered to be symbols of scientific excellence and top performance of the past ten years. This study provided an informetric analysis of 7791 highly cited papers in the environmental sciences category during 2009–2019. Informetric indicators and visualization tools were applied to evaluate and present the performances of journals, countries/territories, institutions, top cited papers, and research hotspots. The results showed that the cumulative number of publications has increased exponentially, suggesting strong development of the environmental sciences category. There were 211 journals publishing highly cited papers, with Energy & Environmental Science as the leading journal. The USA ranked first with the highest number of publications and occupied the core position in the collaboration network, while Mainland China took the first place in independent research output. Review articles have an obvious advantage in terms of achieving high citations. “Adsorption”, “climate change”, and “heavy metal” were the most frequent keywords, with “microplastic” rising rapidly as a new research frontier in recent years. Five research hotspots were visualized from highly cited papers via cluster analysis. Full article

In a wave of global conservationism, Ecuador established two large protected areas in its Amazon region in 1979. One of these is the Reserva de Producción Faunística Cuyabeno (RPFC), located in the northeastern corner of the country. Given that this land was previously managed as commons by local indigenous groups, the establishment of protected areas has had numerous consequences for these people. The research conducted comprised three months’ fieldwork in three of the affected Siona communities, primarily through the use of participant observation. Based on the framework developed by Ensminger, this paper demonstrates how institutional change has occurred in the last few centuries with the arrival of various frontiers overriding the region. This has led to the almost total eradication of traditional institutions and the introduction of a new ideology, namely conservationism. In order to legitimize their existence in the Reserve, indigenous groups are compelled to argue in a conservationist discourse if they want to stay in their ancestral territory. The article discusses tourism as one key impact on the lives of the local Siona, alongside their response to the grabbing process, which takes the form of a re-creation of their identity, including institution shopping from below. This article contributes to the debate on commons grabbing from the perspective of local actors by arguing that institution shopping from below does not necessarily mean a loss of authenticity, considering different ontological perspectives in the process of identity construction.
