Convergence research is driven by specific and compelling problems and requires deep integration across disciplines. The potential of convergence research is widely recognized, but questions remain about how to design, facilitate, and assess such research. Here we analyze a seven-year, twelve-million-dollar convergence project on sustainable climate risk management to answer two questions. First, what is the impact of a project-level emphasis on the values that motivate and tie convergence research to the compelling problems? Second, how does participation in convergence projects (...) shape the research of postdoctoral scholars who are still in the process of establishing themselves professionally? We use an interview-based approach to characterize what the project specifically enabled in each participant’s research. We find that (a) the project pushed participants’ research into better alignment with the motivating concept of convergence research and that this effect was stronger for postdoctoral scholars than for more senior faculty. (b) Postdocs’ self-assessed understanding of key project themes, however, appears unconnected to metrics of project participation, raising questions about training and integration. Regarding values, (c) the project enabled heightened attention to values in the research of a large minority of participants. (d) Participants strongly believe in the importance of explicitly reflecting on values that motivate and pervade scientific research, but they question their own understanding of how to put value-focused science into practice. This mismatch of perceived importance with poor understanding highlights an unmet need in the practice of convergence science. (shrink)

Vietnam’s forests are at risk - carbon offset schemes could be the best chance of saving them, say Dr. Quan-Hoang Vuong and Minh-Hoang Nguyen. The value of forests is deeply ingrained in Vietnamese culture. Rừng vàng, biển bạc” [“forests of gold and seas of silver”] is both a metaphor for Vietnam, and a description of its natural wealth. The phrase is everywhere, from political speeches to daily conversation, as is Nhất phá sơn lâm, nhì đâm hà bá [“the worst crime (...) is to destroy the mountains and forests, the second worst is to kill the river”]. Deforestation is a Vietnamese taboo. (shrink)

Abstract: Forests are areas with a high density of trees, and they play a vital role in the health of the planet. They provide a habitat for a wide variety of plant and animal species, and they help to regulate the climate by absorbing carbon dioxide from the atmosphere. While in 2010, the world had 3.92Gha of forest cover, covering 30% of its land area, in 2019, there was a loss of forest cover of 24.2Mha according to the (...) Global Forest Watch institute. Discovery and classification depend on human experience and effort, so the error in the results of this process can lead to forest fires and disasters. Therefore, deep learning algorithms from artificial intelligence and machine learning sciences have been applied to help specialists avoid false or inaccurate diagnoses when detecting Forest fires in images using a pre-trained convolutional neural network called VGG16. The model was customized to fit the Forest fires classification and then applied to a dataset consisting of (14,000) of the Forests collected from the Kaggle depository. We trained, validated, and tested the modified VGG16 model. The proposed VGG16 model obtained Precision (99.96%), Recall (99.96%), and F1-Score (99.96%). (shrink)

Tropical cyclones and their pertinent natural hazards can cause destructive damage to people and properties. Vietnam, located in the Northwest Pacific basin, is highly vulnerable to tropical cyclones due to its geography (i.e., a long coastline and narrow width). In this paper, we discuss how the negative consequences of tropical cyclones on Vietnam can be exacerbated by climate change and how forests, either in the mountainous or in the coastal regions, play crucial roles in safeguarding the country from tropical cyclones (...) and their pertinent hazards (e.g., landslides and flood). Despite the importance of forests, their protection values are undermined, leading to continuous deforestation of natural forests for socio-economic development. We suggest the social transitions towards eco-surplus culture through more proactive and transparent communication of the destructive outcomes of tropical cyclones and the protection roles of forests in the current climate change era.

Do forest owners’ levels of education or value profiles explain their responses to climate change? The cultural cognition thesis has cast serious doubt on the familiar and often criticized "knowledge deficit" model, which says that laypeople are less concerned about climate change because they lack scientific knowledge. Advocates of CCT maintain that citizens with the highest degrees of scientific literacy and numeracy are not the most concerned about climate change. Rather, this is the group in which cultural polarization is (...) greatest, and thus individuals with more limited scientific literacy and numeracy are more concerned about climate change under certain circumstances than those with higher scientific literacy and numeracy. The CCT predicts that cultural and other values will trump the positive effects of education on some forest owners' attitudes to climate change. Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile. (shrink)

Forests play fundamental roles in the Earth’s ecosystems. With the great capability of carbon sequestration, tropical forests are expected to contribute substantially to reducing the CO2 in Earth’s atmosphere. However, global tropical forest areas have declined drastically over the last few decades due to pressures from socio-economic development pursuit. The current essay aims to demonstrate the ongoing global deforestation crisis and its underlying drivers and discuss the vital roles of tropical forests in the socio-economic development in the face of (...) climate change when developed countries start to tighten the carbon emission control regulations (e.g., European Union’s Carbon Border Adjustment Mechanism). It suggests why developing countries in tropical regions, particularly Vietnam, should not sacrifice forests for short- and medium-term socio-economic goals but capitalize on them to leverage long-term development. Moreover, evidence of Vietnamese political leaders’ commitment to forest protection and sustainable development is also provided. (shrink)

The practice of trading forest carbon credits has gained significant attention as a strategy to combat climate change. By allowing companies to buy and sell credits representing forest carbon sequestration, it aims to create financial incentives for forest preservation. However, a recent report highlights the dangers of commodifying forest carbon if such financial mechanisms overshadow other vital environmental and social values. To understand the complexities of this issue, we can turn to the mindsponge theory (MT), particularly (...) its information-value nexus hypothesis, for valuable insights. (shrink)

Data from the International Space Station reveals that, in some tropical forests, a small percentage of forest leaves are exposed to extreme temperatures. Scientists are concerned and warn that this trend may continue to escalate. This is a consequence of the Earth’s warming process, causing tropical forests to become excessively hot, potentially surpassing the maximum temperature threshold for leaves to photosynthesize. The ultimate result could be the collapse of the flora system.

Uncertainty, insufficient information or information of poor quality, limited cognitive capacity and time, along with value conflicts and ethical considerations, are all aspects thatmake risk managementand riskcommunication difficult. This paper provides a review of different risk concepts and describes how these influence risk management, communication and planning in relation to forest ecosystem services. Based on the review and results of empirical studies, we suggest that personal assessment of risk is decisive in the management of forest ecosystem services. The (...) results are used together with a reviewof different principles of the distribution of risk to propose an approach to risk communication that is effective aswell as ethically sound. Knowledge of heuristics and mutual information on both beliefs and desires are important in the proposed risk communication approach. Such knowledge provides an opportunity for relevant information exchange, so that gaps in personal knowledge maps can be filled in and effective risk communication can be promoted. (shrink)

This paper reviews current initiatives to establish carbon offset forests in suburban and peri-urban environments. While moments of density occur within urban territories the general spatial condition is one of fragmented and patchy networks made up of a heterogeneous mix of residential enclaves, industrial parks, waste sites, infrastructure easements interspersed with forests, agriculture, leftover voids and overlooked open space. These overlooked open spaces have the potential to form a new green urban structure of carbon offset forests as cities respond to (...) the carbon economy. Furthermore such urban spaces are not likely to diminish over time as cities are not only growing larger but are becoming more dispersed according to recent World Bank reports. This strong trend is not limited to developed or developing cities but is a worldwide phenomenon. In the future, policy incentives for carbon sequestration will drive land use change in rural and urban areas alike. The paper documents projects in Blacktown City Council in Western Sydney.

Our latest contribution to the world’s battle against climate and biodiversity crises was an expert commentary on Vietnamese forests and the prospect of carbon credits trade. The article appeared in the Land and Climate Review on Feb. 2, 2024.

Traditionally Ψ is used to stand in for both the mathematical wavefunction (the representation) and the quantum state (the thing in the world). This elision has been elevated to a metaphysical thesis by advocates of the view known as wavefunction realism. My aim in this paper is to challenge the hegemony of the wavefunction by calling attention to a little-known formulation of quantum theory that does not make use of the wavefunction in representing the quantum state. This approach, called Lagrangian (...) quantum hydrodynamics (LQH), is not an approximation scheme, but rather a full alternative formulation of quantum theory. I argue that a careful consideration of alternative formalisms is an essential part of any realist project that attempts to read the ontology of a theory off of the mathematical formalism. In particular, I show that LQH undercuts the central presumption of wavefunction realism and falsifies the claim that one must represent the many-body quantum state as living in a 3n-dimensional configuration space. I conclude by briefly sketching three different realist approaches one could take toward LQH, and argue that both models of the quantum state should be admitted. When exploring quantum realism, regaining sight of the proverbial forest of quantum representations beyond the Ψ is just the first step. (shrink)

Forests, which host nearly 80% of terrestrial biodiversity, play a critical role in climate regulation and the well-being of human societies.

Forests, often described as the lungs of the planet, are vital engines of carbon capture and biomass production. But what determines how efficiently they grow? Scientists have long hypothesized that planting mixtures of tree species, rather than monocultures, enhances forest productivity. A recent comprehensive review by Forrester, Plaga, and Bauhus (2025) delves into the intricate interplay between tree size, stand density, and species mixing, revealing how these factors influence forests’ ability to capture and utilize sunlight—the essential driver of growth.

Abstract: This research employs a Random Forest classification model to predict and assess obesity and cardiovascular disease (CVD) risk based on a comprehensive dataset collected from individuals in Mexico, Peru, and Colombia. The dataset comprises 17 attributes, including information on eating habits, physical condition, gender, age, height, and weight. The study focuses on classifying individuals into different health risk categories using machine learning algorithms. Our Random Forest model achieved remarkable performance with an accuracy, F1-score, recall, and precision all (...) reaching 97.23%. The model's success is attributed to its ability to effectively leverage attributes related to eating habits, physical condition, and demographic factors. Feature importance analysis reveals key factors contributing to accurate predictions. This paper contributes to the field of health analytics by demonstrating the effectiveness of Random Forest in predicting and categorizing health risks. The insights gained from this research have the potential to inform personalized health interventions and contribute to the advancement of precision health strategies. Furthermore, the study highlights the importance of leveraging machine learning techniques for health risk assessment in diverse populations. (shrink)

This article addressed historical aspects of the political economy involving sustained forest ecology in Sierra Leone as a whole, with emphasis on the Freetown Peninsula and its surrounding communities. Attention is paid to cultural, social and economic aspects involving forest livelihoods of residents on the Freetown Peninsula and far afield. The term 'Political Economy' is used in this situation to denote the relationship between the economics of people's livelihoods and public policy (in relation to the management of legislative (...) procedures) in ensuring that resources in the forest environment is sustainably managed to cater for the livelihood needs of people in Sierra Leone, while at the same time maintaining a balance in protecting the forest ecosystems. The paper has provided a critical review of the political economy of forest ecology in the country on the basis of scholarly discourses, and its applicability in adapting to the fragile political administrative management Sierra Leone have (and is continuing to) experienced.

As humans continue to reshape the world’s tropical forests, the impacts go far beyond the loss of forest cover. A new study by Pinho et al. (2025), published in Nature Ecology & Evolution, reveals that human-driven forest loss and degradation are fundamentally altering the composition and function of tree communities across Brazil’s Amazon and Atlantic Forest regions.

Efforts to restore Brazil’s Atlantic Forest—a globally significant biodiversity hotspot—are falling short of their full ecological potential, according to a recent study in Perspectives in Ecology and Conservation. Although restoration initiatives have employed high-diversity plantings, the species composition of these sites fails to reflect the richness and heterogeneity of nearby native forests.

In this study, we consider that enabling young people to experience direct contact with nearby natural environments can positively influence their knowledge and feelings about the biodiversity that occurs there, contributing to its protection and conservation for current and future generations. In this study, we explore how teenagers (n = 17) aged between 13 and 17 years old describe and perceive the nearby natural environment before and after an interpretive trail in Una, Bahia, Brazil. Participants were asked to draw the (...) Atlantic Forest with colored pencils on white paper and, based on the drawing, they answered the following questions: “What is in your drawing? and “What is happening in your drawing?,” in addition to other information such as the title of the drawing, difficulty of the activity, and sociodemographic aspects. Content analysis was used to analyze the information collected. From the drawings and responses of the participants, categories related to knowledge, experiences, and types of relationships with the visited place emerged. (shrink)

The sustainable management of forests, vital for biodiversity and climate resilience, is being transformed by three-dimensional (3D) point cloud technology [2].

As global temperatures rise and extreme weather events become more frequent, the focus on urban trees is intensifying. Research highlights their crucial role in mitigating climate change, improving public health, and providing significant economic benefits.

One of the most influential and controversial schools of 20th century Thomism—especially in North America—is the “River Forest School” or “River Forest Thomism”. And one of the most influential and controversial theses associated with that school is the thesis that metaphysics cannot be established as a distinct and autonomous science unless one has already proven the existence of a positively immaterial being. The purpose of this paper is to show that River Forest Thomism cannot and should not (...) be reduced to that controversial thesis. As such, rejection of the thesis cannot and should not constitute a rejection of the school. Indeed, as soon as we understand what River Forest Thomism was really about, it will become clear that all Thomists should be River Forest Thomists. (shrink)

Commentaires sur le livre Dealing With Differences: Dramas of Mediating Public Disputes, Oxford, Oxford University Press, 2009.

Forests are vital to global climate stability and agricultural productivity. As climate change and food insecurity intensify, the role of forests in safeguarding food systems and enhancing climate resilience becomes increasingly critical.

This paper examines philosophical debates about concepts of biodiversity, making the case for conceptual pluralism. Taking a pragmatist perspective, I argue that normative concepts of biodiversity and eco-centric concepts of biodiversity can serve different purposes. The former would help stress the values of local communities, which have often been neglected by both early scientific approaches to conservation, and by policy makers prioritizing the political or economic interests of specific groups. The latter would help build local research programs independent of pressures (...) from economic or political actors. I employ a case study on environmental research on walnut forests in Kyrgyzstan in support of my argument. Against tendencies to frame different understandings of biodiversity in terms of geographical areas, I propose an interpretation drawing on the philosophy of ecology. Adherence to environmental pragmatism enables a sufficiently complex picture of developing environmental research in the area, capturing issues about scientific framings and local understandings.

Forests have evolved in human perception from mere timber reserves to complex ecosystems that sustain biodiversity and deliver critical services such as carbon storage, water regulation, and climate resilience. Yet, as climate change accelerates pest outbreaks and invasive species spread through global trade, insecticides remain a cornerstone of forest pest management strategies [2].

There are numerous ways in which “the particular”—particular individuals, particular ideologies, values, beliefs, and perspectives—are sometimes overlooked, ignored, or even driven out of the healthcare profession. In many such cases, this is bad for patients, practitioners, and the profession. Hence, we should seek to find a place for the particular in health care. Specific topics that I examine in this essay include distribution of health care based on the particular needs of patients, the importance of protecting physicians’ right to conscientious (...) objection, the value in tolerating a plurality of moral and medical perspectives within the field, and more. Ultimately, as the imagery in the essay’s title suggests, I argue that if one cares about the “well-being” of the medical profession, then one should seek to avoid destroying the many diverse and particular entities that constitute it.

As cities continue to expand, the transition zones between urban areas and natural landscapes—known as wildland-urban interfaces (WUIs)—are becoming vital spaces for both climate adaptation and biodiversity.

Forests provide far more than timber and climate regulation—they also offer vital cultural ecosystem services, such as environmental education, which foster ecological awareness and sustainable behavior [1,2]. Despite its significance, this service remains among the least assessed within ecosystem service studies [3]. Addressing this oversight, Tiemann and Ring [4] conducted a comprehensive analysis to quantify and map access to forest-related environmental education in Saxony, Germany.

In this piece, I develop a philosophical account of environmental reverence, as induced by more-than-human entities and environments. Utilizing a relational ethical framework, I conceive of environmental reverence as a moral emotion, which through habituation and cultivation–carries the potential to grow into a fully fledged environmental virtue. By reference to the empirical, psychological literature, I show that environmental reverence is positively affective (i.e., induces subjective wellbeing), inherently motivating, and promotes efficacious conservation behaviors. So conceived, reverence is constrained by a set (...) of both internal and external success conditions; its proper implementation thus requires on-the-ground relationship building between communities and the local, biodiverse spaces near which they dwell. I focus on the important role that reverence plays in motivating the efficacious conservation of sylvan ecosystems, drawing on eco-anthropological research into the high concentrations of biodiversity found in residentially managed ‘sacred groves’. Altogether, I recommend a few first-order, ethical prescriptions: first, mass environmental discourse ought to highlight the motivational efficacy of cultivating cultural narratives that center environmental reverence and the key, carbon-sequestering role that forests play in climate-change mitigation. Finally, it is imperative for environmental ethicists to elevate the epistemic status afforded to traditional ecological and residential land managers. (shrink)

The diversion of forest land for development requires accurate tree enumeration to assess environmental impact. Traditional methods, like manual counting and sampling, are labor-intensive, time-consuming, and prone to error. This project leverages high-resolution satellite and drone imagery, combined with advanced image processing and machine learning, to automate tree counting. Our system includes analytical tools, and provides authorities with historical environmental data (like rainfall, temperature, humidity) for informed decision-making. With a userfriendly interface and appealing data visualizations, it also integrates Google (...) Maps API for user-generated satellite imagery. This solution aims to enhance accuracy, efficiency, and scalability in tree enumeration, supporting sustainable forest management and regulatory compliance. (shrink)

Canada’s ambitious Two Billion Trees (2BT) program aims not only to mitigate climate change but also to safeguard biodiversity and improve human well-being. Remarkably, the country has 19.1 million hectares of land suitable for forest restoration—15 times more than the area needed to meet the program’s target (1.2 million hectares). The real challenge, therefore, is not where to plant but how to plant wisely.

Pereira’s “The Projective Theory of Consciousness” is an experimental statement, drawing on many diverse sources, exploring how consciousness might be produced by a projective mechanism that results both in private selves and an experienced world. Unfortunately, pulling together so many unrelated sources and methods means none gets full attention. Furthermore, it seems to me that the uncomfortable breadth of this paper unnecessarily complicates his project; in fact it may hide what it seeks to reveal. If this conglomeration of diverse sources (...) and methods were compared to trees, the reader may feel like the explorer who cannot see the forest for the trees. Then again, it may be the author who is so preoccupied with foreground figures that the everpresent background is ultimately obscured. (shrink)

Once considered a minor concern confined to South African pine plantations, Diplodia sapinea has now emerged as a significant global threat to both natural and commercial forests, particularly across Europe. Historically mischaracterized as a pathogen that infects only through wounds, recent research has redefined D. sapinea as a latent endophyte—an organism that inhabits healthy pine tissues asymptomatically, only triggering disease when trees experience environmental stress [2].

Clearings of the Forest (Claros del Bosque, 1977), one of the most poetic and challenging works of María Zambrano’s thought, cannot be approached from a breathless paradigm. For the immersion in these clearings take us into the breathing of being that we contemplate alongside the more obvious physiological breathing, the breathing of life. In this work, Zambrano proposes a poetic and mystical phenomenology of the breathing of being through the breathing of its word. Thus, to recover contact with this (...) inner breathing could be to recover the lost chant of the word. This essay does not pretend to be a detailed analysis of Zambrano’s thought as a whole, nor of the vibrant mystery that her clearings reveal. The purpose is to uncover the fundamental role that breathing plays in this poetic-philosophical journey, along with other symbols such as light or love, with the question of what place this type of philosophical exercise occupies today in the classrooms of contemporary universities.

Furthermore, studies emphasize the importance (...) of rare trees, some of which remain undiscovered, in maintaining the overall health and resilience of forest ecosystems. (shrink)

Wildfires are formidable and unpredictable natural forces that have shaped ecosystems for thousands of years. Yet, in an era of accelerating climate change and expanding human development into fire-prone regions, understanding how wildfires behave has never been more urgent. A recent global synthesis by Cruz, Hoffman, and Fernandes (2025) brings together two decades of field-based research on fire dynamics, with a focus on forests and shrublands—two ecosystems increasingly vulnerable to wildfire impacts.

Tropical forests, renowned for their biodiversity and role in climate regulation, are increasingly affected by human activities such as deforestation, agriculture, and atmospheric nutrient deposition. In response to these pressures, a recent meta-analysis by Cárate Tandalla, Homeier, and Batáry [2] offers critical insights into how nutrient additions influence the growth of tropical tree seedlings—key indicators of forest regeneration and resilience.

Roderic Page’s new book, Tangled Trees: Phylogeny, Cospeciation and Coevolution (2003), is a worthwhile read for anyone interested in either methodological issues in systematics, or how organisms shape one another’s selective environments. “Cospeciation,” for the uninitiated, is the concurrent speciation of two or more lineages that are ecologically associated (e.g. host-parasite associations, as well as mutualistic or symbiotic associations). “Coevolution,” in contrast, is the reciprocal adaptation of hosts and parasite taxa. The main focus of Page’s book is thus when, how (...) and why the branching process of host taxa mirrors that of parasite taxa. “Parasite” here is broadly conceived to be anything from a louse to a virus to a retrotransposon, and “host” may be anything from a genome to a whale.

Forest restoration in Europe has evolved significantly over the past two centuries, transitioning from reactive, production-oriented efforts to a modern, multifunctional approach centered on biodiversity and ecosystem resilience. A recent synthesis of expert insights from 18 European countries reveals how environmental, political, social, and economic forces have shaped this trajectory [2].

Primary forests, among the most intact and ecologically valuable ecosystems, are facing alarming rates of degradation across Europe. In a comprehensive study, Barredo et al.

The findings reveal a significant increase in both the frequency and severity of disturbances, largely driven by human activities, underscoring the urgent need for enhanced protection measures.

Some neotropical social wasps which are associated with some vertebrates and other insects like ants, and these interactions are reported for decades, but little is known about the presence of these in the Caatinga and Atlantic Forest. This study describes the first association’s record between nests of Polybia rejecta (Fabricius) wasp and Azteca chartifex Forel ants in the transition area of the Atlantic Forest and Caatinga in Rio Grande do Norte. The observations were in a private forest (...) in Monte Alegre, from October 2009 to September 2014 through active search for colonies, use of ad libitum method, photography and collection of specimens with traceability. In the study area were found four active colonies and one abandoned of P. rejecta, all associated with nests of A. chartifex with approach of 20-30 cm. It was found that when the colony of P. rejecta was disturbed, they became aggressive towards the disturbance object, whereas the ants gathered in order to fend off a potential predators. These interactions appear to benefit wasps and ants, it is assumed that is possible that wasps attack ants’s predators, whereas the ants attack the wasps’s predators. This study corroborates the hypothesis that the association between the social wasps P. rejecta and A. chartifex ants is beneficial for both species, and probably the wasps are the most benefited, but also shows the non-exclusivity of this association for the biomes up then reported.

As global demand for timber continues to rise, Eucalyptus species have emerged as a cornerstone of commercial forestry, prized for their rapid growth rates and adaptability to diverse environmental conditions. However, the expansion of Eucalyptus plantations—particularly beyond their native habitats—has been accompanied by increasing vulnerability to foliar fungal pathogens. These pathogens, which target leaves and shoots, pose a significant threat to tree health, productivity, and long-term plantation sustainability.

The Forrest-Armstrong argument, as reconfigured by David Lewis, is a reductio against an unrestricted principle of recombination. There is a gap in the argument which Lewis thought could be bridged by an appeal to recombination. After presenting the argument, I show that no plausible principle of recombination can bridge the gap. But other plausible principles of plenitude can bridge the gap, both principles of plenitude for world contents and principles of plenitude for world structures. I conclude that the Forrest-Armstrong argument, (...) when fortified in one of these ways, demands that unrestricted recombination be rejected. The appropriate restriction comes from a consideration of what world structures are possible. I argue that, although there are too many worlds to form a set, for any world, the individuals at that world do form a set. To defend it I invoke a principle of Limitation of Size together with an iterative conception of structure. (shrink)

Amid escalating threats to biodiversity, Lima, Alvarado, and Araujo (2025) explored how different landscape features influence bird diversity in Brazil’s Caatinga—the largest tropical dry forest in South America. Their study examined two key measures of biodiversity: α-diversity, which reflects species richness within local sites, and β-diversity, which captures variation in species composition across different sites. Specifically, they investigated how these biodiversity dimensions respond to forest cover, landscape heterogeneity, and the spatial configuration of habitats within agricultural landscapes.
