Disease Risk from Human-Environment Interactions: Environment and Development Economics for Joint Conservation-Health Policy
Emergence of COVID-19 joins a collection of evidence that local and global health are infuenced by human interactions with the natural environment. Frameworks that simultaneously model decisions to interact with natural systems and environmental mechanisms of zoonotic disease spread allow for identifcation of policy levers to mitigate disease risk and promote conservation.
Improving rural health care reduces illegal logging and conserves carbon in a tropical forest
Tropical forest loss currently exceeds forest gain, leading to a net greenhouse gas emission that exacerbates global climate change. This has sparked scientific debate on how to achieve natural climate solutions. Central to this debate is whether sustainably managing forests and protected areas will deliver global climate mitigation benefits, while ensuring local peoples’ health and wellbeing. Here, we evaluate the 10-y impact of a human-centered solution to achieve natural climate mitigation through reductions in illegal logging in rural Borneo: an intervention aimed at expanding health care access and use for communities living near a national park, with clinic discounts offsetting costs historically met through illegal logging. Conservation, education, and alternative livelihood programs were also offered. We hypothesized that this would lead to improved health and well-being, while also alleviating illegal logging activity within the protected forest.
Technical guidelines on rapid risk assessment for animal health threats
When an imminent threat or emergency arises from an animal health event, it is important to conduct a rapid risk assessment (RRA) that informs animal health decision-makers of the most efficient control measures that they can take to control the disease concerned. These technical guidelines on rapid risk assessment provide a simple and practical tool that assists decision-makers in veterinary departments in conducting qualitative RRAs on the emergence, incursion and/or spread of animal health events caused by infectious diseases.
Training Manual on Wildlife Diseases and Surveillance
The OIE launched a global programme of capacity building for OIE Delegates and OIE Focal Points on different topics in 2009. The aim of this programme and the related regional training workshops is to explain and clarify the roles and responsibilities of the Focal Points nominated by the OIE Delegates and to facilitate consistency and harmonisation amongst OIE Members when assigning responsibilities to these officials... This training manual contains the core curriculum for the part of a workshop intended to inform and assist National Focal Points for Wildlife of the World Organisation for Animal Health (OIE) to gather and report information regarding the occurrence of wild animal pathogens and diseases in each of the OIE Members.
Ecological Countermeasures for Preventing Zoonotic Disease Outbreaks: When Ecological Restoration is a Human Health Imperative
Ecological restoration should be regarded as a public health service. Unfortunately, the lack of quantitative linkages between environmental and human health has limited recognition of this principle. The advent of the COVID-19 pandemic provides the impetus for further discussion. We propose ecological countermeasures as highly targeted, landscape-based interventions to arrest the drivers of land use-induced zoonotic spillover. We provide examples of ecological restoration activities that reduce zoonotic disease risk and a five-point action plan at the human-ecosystem health nexus. In conclusion, we make the case that ecological countermeasures are a tenet of restoration ecology with human health goals.
CHANS-Law: Preventing the Next Pandemic through the Integration of Social and Environmental Law
Zoonotic viruses have sacrifced hundreds of millions of people throughout human history. There are currently 1.7 million unidentifed viruses estimated to be circulating in mammal and bird populations. It is foreseeable that in the near future, another of these will transmit to people, heralding the start of the next pandemic-- one potentially more deadly than COVID-19. At the core of this article is a call for pre-emptive protection of the natural environment and its regenerative systems as the frst fundamental step in the prevention of future epidemics and pandemics.
Developing a One Health Approach by Using a Multi-Dimensional Matrix
The One Health concept that human, animal, plant, environmental, and ecosystem health are linked provides a framework for examining and addressing complex health challenges. This framework can be represented as a multi-dimensional matrix that can be used as a tool to identify upstream drivers of disease potential in a concise, systematic, and comprehensive way. The matrix can involve up to four dimensions depending on users’ needs. This paper describes and illustrates how the matrix tool might be used to facilitate systems thinking, enabling the development of effective and equitable public policies. The multidimensional One Health matrix tool will be used to examine, as an example, global human and animal fecal wastes. The fecal wastes are analyzed at the microbial and population levels over a timeframe of years. Political, social, and economic factors are part of the matrix and will be examined as well. The One Health matrix tool illustrates how foodborne illnesses, food insecurity, antimicrobial resistance, and climate change are inter-related. Understanding these inter-relationships is essential to develop the public policies needed to achieve many of the United Nations’ Sustainable Development Goals.
A Framework to Guide Planetary Health Education
People around the world are increasingly facing the pressing challenges of today's interconnected environmental, social, and health crises. The COVID-19 pandemic has been an important wake-up call reminding us that we need a healthy planet to ensure the health of all people. The emerging field of planetary health is a framework for understanding these interconnections and identifying solutions to the complex challenges confronting our civilization.
Pollution and health: a progress update
The Lancet Commission on pollution and health reported that pollution was responsible for 9 million premature deaths in 2015, making it the world’s largest environmental risk factor for disease and premature death. We have now updated this estimate using data from the Global Burden of Diseases, Injuriaes, and Risk Factors Study 2019. We find that pollution remains responsible for approximately 9 million deaths per year, corresponding to one in six deaths worldwide. Reductions have occurred in the number of deaths attributable to the types of pollution associated with extreme poverty. However, these reductions in deaths from household air pollution and water pollution are offset by increased deaths attributable to ambient air pollution and toxic chemical pollution (ie, lead).
Wildlife Trade, Pandemics and the Law: Fighting this year's virus with last year's law
This paper is the follow-up to a brief survey of legislation conducted by Legal Atlas in June of 2020 on existing legal approaches to controlling zoonotic disease risk in the context of wildlife trade. The original research was a rapid review conducted to provide some background in response to the numerous articles in international media calling for legal reforms during the first months of the 2020 COVID pandemic.
Report of the Scientific Task Force on Preventing Pandemics
The report contains key findings and recommendations for research and action to inform pandemic prevention. The task force found that evidence strongly establishes spillover of viruses from wildlife into people, sometimes via livestock, as the root cause of pandemic risk. Spillover of the viruses currently understood to have pandemic potential occurs from land use change, and in particular the destruction of tropical forests, expansion of agricultural lands, especially near human settlements, livestock and farmed wildlife intensification, and wild animal hunting and trade.
Working Together to Protect Australia in the Age of Pandemics
The COVID-19 pandemic has infiltrated every level of social, cultural and political life and has demonstrated the truly devastating effects of ineffective pandemic management systems. Yet, the likelihood of another pandemic occurring in the short to medium term is greater than ever. The drivers of pandemics are not improving. Anthropogenic drivers, including agricultural intensification, land-use changes such as deforestation and urbanisation, wildlife trade, and climate change are all contributing to what has been called the ‘era of pandemics.
International law reform for One Health notifications
Epidemic risk assessment and response relies on rapid information sharing. Using examples from the past decade, we discuss the limitations of the present system for outbreak notifications, which suffers from ambiguous obligations, fragile incentives, and an overly narrow focus on human outbreaks. We examine existing international legal frameworks, and provide clarity on what a successful One Health approach to proposed international law reforms— including a pandemic treaty and amendments to the International Health Regulations—would require. In particular, we focus on how a treaty would provide opportunities to simultaneously expand reporting obligations, accelerate the sharing of scientific discoveries, and strengthen existing legal frameworks, all while addressing the most complex issues that global health governance currently faces.
Role of Pollution on the Selection of Antibiotic Resistance and Bacterial Pathogens in the Environment
There is evidence that human activity causes pollution that contributes to an enhanced selection of bacterial pathogens in the environment. In this review, we consider how environmental pollution can favour the selection of bacterial pathogens in the environment. We specifically discuss pollutants released into the environment by human activities (mainly human waste) that are associated with the selection for genetic features in environmental bacterial populations that lead to the emergence of bacterial pathogens.
Outbreaks of Vector-Borne and Zoonotic Diseases are Associated with Changes in Forest Cover and Oil Palm Expansion at Global Scale
Deforestation is a major cause of biodiversity loss with a negative impact on human health. This study explores at global scale whether the loss and gain of forest cover and the rise of oil palm plantations can promote outbreaks of vector-borne and zoonotic diseases.
Investigating the Risks of Removing Wild Meat from Global Food Systems
The COVID-19 pandemic has led to calls to prohibit wild meat consumption, to protect public health and biodiversity. However, Booth et al. demonstrate that the sudden removal of wild meat from food systems could negatively impact people and nature. Wildlife trade policy interventions need to consider tele-couplings between food systems and nature.
The United Nations Sustainable Development Goals on Biodiversity, Climate Change and Health Agenda
A stable climate and healthy ecosystems provide the basic underpinnings of human welfare and development. Failure to tackle global warming, mass biodiversity loss and other pressing environmental problems threatens the achievement of every single one of the Sustainable Development Goals (SDGs), with catastrophic consequences that will hit the poorest and most vulnerable communities first and hardest (UNEP 2021). International action has not matched the scale of the challenge.
Wild Animal and Zoonotic Disease Risk Management and Regulation in China: Examining gaps and One Health opportunities in scope, mandates, and monitoring systems
Emerging diseases of zoonotic origin such as COVID-19 are a continuing public health threat in China that lead to a significant socioeconomic burden. This study reviewed the current laws and regulations, government reports and policy documents, and existing literature on zoonotic disease preparedness and prevention across the forestry, agriculture, and public health authorities in China, to articulate the current landscape of potential risks, existing mandates, and gaps.
Aquaculture at the Crossroads of Global Warming and Antimicrobial Resistance
In many developing countries, aquaculture is key to ensuring food security for millions of people. It is thus important to measure the full implications of environmental changes on the sustainability of aquaculture. We conduct a double meta-analysis (460 articles) to explore how global warming and antimicrobial resistance (AMR) impact aquaculture. We calculate a Multi-Antibiotic Resistance index (MAR) of aquaculture-related bacteria (11,274 isolates) for 40 countries, of which mostly low- and middle-income countries present high AMR levels.
Taking a Multisectoral, One Health Approach: A Tripartite Guide to Addressing Zoonotic Diseases in Countries
Every day we hear about health challenges at the human-animal-environment interface. Zoonotic diseases such as avian influenza, rabies, Ebola, and Rift Valley fever, as well as food-borne diseases and antimicrobial resistance, continue to have major impacts on health, livelihoods, and economies. Many countries recognize the benefits of taking a One Health approach that is multisectoral and multidisciplinary to build national mechanisms for coordination, communication, and collaboration to address health threats at the human-animal environment interface.
Biodiversity and Human Health Interlinkages in Higher Education Offerings: A First Global Overview
Biodiversity is inextricably linked to human health. As an important area of research of the Convention on Biological Diversity and a key avenue for the dissemination of biodiversity and health knowledge, we investigated how well-embedded biodiversity and health interlinkages are in institutional higher education offerings.
Strategies for Implementing a One Welfare Framework into Emergency Management
During emergencies, people’s decision-making and actions are strongly influenced by their relationship with their animals. In emergency management, a holistic approach is needed which recognises the important interrelationships between animal welfare, human well-being, and the physical and social environment. It is also vital to break down barriers of collaboration between individuals, organisations, and the community. One Welfare, a concept with human–animal-environment interdependencies at its core, provides a framework to achieve this. Successful implementation of a transformative change will require positive strategies to deal with challenges and to ensure that animals are truly integrated into emergency management, not just included as an aside.
A One Health Glossary to Support Communication and Information Exchange Between Human Health, Animal Health and Food Safety Sectors
Collaboration across sectors, disciplines and countries is a key concept to achieve the overarching One Health (OH) objective for better human, animal and environmental health. Differences in terminology and interpretation of terms are still a significant hurdle for cross-sectoral information exchange and collaboration within the area of OH including One Health Surveillance (OHS). The development of the here described glossary is a collaborative effort of three projects funded within the One Health European Joint Programme (OHEJP).
Does deforestation drive visceral leishmaniasis transmission? A casual analysis
Vector-borne diseases (VBDs) are important contributors to the global disease burden and are a key factor in perpetuating economic inequality. Although environmental changes are often cited as drivers of VBDs, the link between deforestation and VBD occurrence remains unclear. Here, we examined this relationship in detail using the spread of visceral leishmaniasis (VL) in São Paulo state (Brazil) as the case study.
A Tool for Rapid Assessment of Wildlife Markets in the Asia-Pacific Region for Risk of Future Zoonotic Disease Outbreaks
Decades of warnings that the trade and consumption of wildlife could result in serious zoonotic pandemics have gone largely unheeded. Now the world is ravaged by COVID-19, with tremendous loss of life, economic and societal disruption, and dire predictions of more destructive and frequent pandemics. There are now calls to tightly regulate and even enact complete wildlife trade bans, while others call for more nuanced approaches since many rural communities rely on wildlife for sustenance. Given pressures from political and societal drivers and resource limitations to enforcing bans, increased regulation is a more likely outcome rather than broad bans. But imposition of tight regulations will require monitoring and assessing trade situations for zoonotic risks. We present a tool for relevant stakeholders, including government authorities in the public health and wildlife sectors, to assess wildlife trade situations for risks of potentially serious zoonoses in order to inform policies to tightly regulate and control the trade, much of which is illegal in most countries. The tool is based on available knowledge of different wildlife taxa traded in the Asia-Pacific Region and known to carry highly virulent and transmissible viruses combined with relative risks associated with different broad categories of market types and trade chains.
Guidance on mainstreaming biodiversity for nutrition and health
While human ingenuity and innovation have made considerable strides in meeting growing demands for food, shelter and energy over the past century, this progress has carried very high social and environmental costs (1). At present, more than one third of the world’s land surface and nearly 75% of freshwater resources are devoted to crop or livestock production (2). These impacts could rise 50–90% by 2050 without a significant transformation of global food systems (2–4). At the same time, the global food system – which fails to provide all people with healthy, safe, affordable and sustainable diets – is a central factor in current trends of malnutrition in all its forms (1,5–7). Poor diets have now become the single-most important driver of mortality globally accounting for nearly 11 million premature adult deaths per year (7).
Strengthening Health Security Across the Globe: Progress and Impact of United States Government Investments in the Global Health Security Agenda
In 2020, the United States partnered with over 40 countries, including 19 Global Health Security Agenda (GHSA) countries (called Intensive Support countries) described in this report, to provide operational and technical assistance to build their health security capacities. The need for these capacities in every country has never been more clear. As of July 6, 2021, more than 3.9 million people have died and over 183 million people have been infected by COVID-19 in more than 200 countries.
Manual for the management of operations during an animal health emergency
This manual provides guidelines for countries and relevant local, national, regional and international organizations to prepare for and manage operations during animal health emergencies.
Practical Actions to Operationalize the One Health Approach in the Asian Development Bank
One Health is an approach to human, animal, plant, and ecological health challenges that starts from a simple premise: these are all interconnected, and their solution demands communication, coordination, and collaboration across multiple sectors, disciplines, and levels of government. Using One Health as a framework is key to post-coronavirus disease (COVID-19) green economic recovery, reaching the Sustainable Development Goals, and global health security. The One Health concept is rapidly gaining traction in the development space and in developing member countries (DMCs) of the Asian Development Bank (ADB).
Land Use-Induced Spillover: A Call to Action to Safeguard Environmental, Animal, and Human Health
The rapid global spread and human health impacts of SARS-CoV-2, the virus that causes COVID-19, show humanity’s vulnerability to zoonotic disease pandemics. Although anthropogenic land use change is known to be the major driver of zoonotic pathogen spillover from wildlife to human populations, the scientific underpinnings of land use-induced zoonotic spillover have rarely been investigated from the landscape perspective. We call for interdisciplinary collaborations to advance knowledge on land use implications for zoonotic disease emergence with a view toward informing the decisions needed to protect human health.
Coronavirus Testing Indicates Transmission Risk Increases along Wildlife Supply Chains for Human Consumption in Viet Nam
Outbreaks of emerging coronaviruses in the past two decades and the current pandemic of a novel coronavirus (SARS-CoV-2) that emerged in China highlight the importance of this viral family as a zoonotic public health threat.
Information About Zoonotic Disease Risks Reduces Desire to Own Exotic Pets Among Global Consumers
Demand for exotic pets is a substantial driver of the illegal wildlife trade. Previous work has suggested that this demand could be reduced by conservation marketing messaging highlighting the potential consequences to individual purchasers, in the form of zoonotic disease risks, or legal ramifications. Such work, however, has been limited only to respondents from culturally Western countries, and has not accounted for how underlying attitudes to the keeping of exotic pets may influence desire to own one, or affect the effectiveness of demand reduction messaging.
Small Mammal Glucocorticoid Concentrations vary with Forest Fragment Size, Trap Type, and Mammal Taxa in the Interior Atlantic Forest
Species that live in degraded habitats often show signs of physiological stress. Glucocorticoid hormones (e.g., corticosterone and cortisol) are often assessed as a proxy of the extent of physiological stress an animal has experienced. Our goal was to quantify glucocorticoids in free-ranging small mammals in fragments of Interior Atlantic Forest.
Climate Change-Triggered Land Degredation and Planetary Health: A Review
Land is a vital natural resource for human socio-ecological wellbeing. Around the world, land is being degraded due to various natural and anthropogenic factors such as flooding, wind erosion, agriculture and human settlement, and anthropogenic climate change. While significant research has been conducted on the separate dyads of: (1) anthropogenic climate change and land degradation and (2) land degradation and health, limited consideration has been given to the cause-and-effect relationships between anthropogenic climate change-triggered land degradation and planetary health consequences.
Antimicrobial Resistance and Environmental Health: A Water Stewardship Framework for Global and National Action
Antimicrobial resistance (AMR) is a global health crisis that affects all life on Earth. In 2015, the World Health Organization developed guidance to combat AMR in accordance with a One Health framework considering human, animal, and environment sectors of planetary health. This study reviewed global guidance and 25 National Action Plans to evaluate thematic priorities in One Health AMR approaches using a novel framework that additionally facilitated the identification of water-related stewardship gaps, as water resources are recognized as the primary environmental AMR reservoir and dissemination pathway. This review found that global and national stewardship primarily focuses on mitigating antibiotic use in the human and animal sectors, overlooking environmental drivers, particularly diverse environmental waters.
A Systems Approach to Evaluate One Health Initiatives
Challenges calling for integrated approaches to health, such as the One Health (OH) approach, typically arise from the intertwined spheres of humans, animals, and ecosystems constituting their environment. Initiatives addressing such wicked problems commonly consist of complex structures and dynamics. As a result of the EU COST Action (TD 1404) “Network for Evaluation of One Health” (NEOH), we propose an evaluation framework anchored in systems theory to address the intrinsic complexity of OH initiatives and regard them as subsystems of the context within which they operate.
Land-use Change and Rodent-borne Diseases: Hazards on the Shared Socioeconomic Pathways
Land-use change has a direct impact on species survival and reproduction, altering their spatio-temporal distributions. It acts as a selective force that favours the abundance and diversity of reservoir hosts and affects host-pathogen dynamics and prevalence. This has led to land-use change being a significant driver of infectious diseases emergence.
Post COVID-19: A Solution Scan of Options for Preventing Future Zoonotic Epidemics
The crisis generated by the emergence and pandemic spread of COVID-19 has thrown into the global spotlight the dangers associated with novel diseases, as well as the key role of animals, especially wild animals, as potential sources of pathogens to humans. There is a widespread demand for a new relationship with wild and domestic animals, including suggested bans on hunting, wildlife trade, wet markets or consumption of wild animals. However, such policies risk ignoring essential elements of the problem as well as alienating and increasing hardship for local communities across the world, and might be unachievable at scale. There is thus a need for a more complex package of policy and practical responses.
Biodiversity and Health in the Urban Environment
A key research gap is to understand—and evidence—the specific causal pathways through which biodiversity affects human health. A mechanistic understanding of pathways linking biodiversity to human health can facilitate the application of nature-based solutions in public health and influence policy. Research integration as well as cross-sector urban policy and planning development should harness opportunities to better identify linkages between biodiversity, climate and human health. Given its importance for human health, urban biodiversity conservation should be considered as public health investment.
Forests Moderate the Effectiveness of Water Treatment at Reducing Childhood Diarrhea
Environmental degradation has been associated with increased burden of diseases such as malaria, diarrhea, and malnutrition. As a result, some have argued that continuing ecosystem change could undermine successes in global health investments. Here we conduct an empirical study to investigate this concern. Child deaths due to diarrhea have more than halved since the year 2000, partly due to increased access to improved water, sanitation and hygiene (WASH). We examine how the effectiveness of a water quality treatment may vary as a function of upstream watershed condition.
PAHO One Health: A Comprehensive Approach for Addressing Health at the Human-Animal-Environment Interface
The aim of this policy on One Health is to foster coordination and collaboration among the different governance frameworks of human, animal, plant, and environmental health programs in order to better prevent and prepare for current and future health challenges at the human-animal-environment interface.
Gaps in Health Security Related to Wildlife and Environment Affecting Pandemic Prevention and Preparedness
Improved health security is crucial for global and national health systems to counter infectious disease epidemics and their wide-scale socioeconomic consequences. The importance of a One Health multisectoral and collaborative approach – one that recognizes the connection between the health of humans, animals and ecosystems – has been acknowledged for years following introduction of the term in the early 2000s. Although significant advancements in multisectoral coordination have been made over the past decade, the overwhelming focus has been on human and domestic animal health; scant attention has been paid to the risks and impacts of zoonotic diseases at wildlife–human or wildlife–livestock interfaces, or to the role of changing environmental conditions. The consequences of this neglect have been costly and deadly with thousands of known zoonotic disease outbreaks in recent decades linked to wildlife...
Global Hotspots and Correlates of Emerging Zoonotic Diseases
Zoonoses originating from wildlife represent a significant threat to global health, security and economic growth, and combatting their emergence is a public health priority. However, our understanding of the mechanisms underlying their emergence remains rudimentary. Here we update a global database of emerging infectious disease (EID) events, create a novel measure of reporting effort, and fit boosted regression tree models to analyze the demographic, environmental and biological correlates of their occurrence.
Good emergency management practice: The essentials
Animal health emergencies arising from infectious diseases and other threats have a high potential to spread rapidly within a country or around the world. These events appear to be increasing as a result of growing animal populations, their concentration and market intensification, human and animal movements, and global trade. This trend is enhanced by the management capacity issues of animal health services as has been evident in the difficulties faced during the COVID-19 pandemic for field service delivery. Animal health emergencies globally impact the food security and livelihoods of nearly half of the 900 million people living in poverty who depend on livestock to survive. They can, therefore, significantly impede progress towards achieving the sustainable development goals. When high impact emerging and zoonotic diseases are involved, early and coordinated responses can prevent the next pandemic.
One Health legislation: Contributing to pandemic prevention through law
The COVID-19 pandemic and other emerging infectious diseases, as well as the continuing threat of antimicrobial resistance (AMR), are reminding us of the close connections between human, animal and environmental health and the urgent need to address them in a holistic manner. Among newly discovered or emerging infectious diseases (EIDs), 75 percent are zoonotic (i.e. transmitted from animals to humans) (Taylor, Latham and Woolhouse, 2001). The unregulated expansion of livestock farming encroaches upon pristine habitats, pushing domestic animals, humans and wildlife into closer and more frequent contact, creating the same tinderbox for disease in animals as they do in humans (FAO, 2011a). Deforestation and other land use changes have an important part in the emergence of disease (Wilcox and Ellis, 2006).
Land-based Measures to Mitigate Climate Change: Potential and Feasibility by Country
Land-based climate mitigation measures have gained significant attention and importance in public and private sector climate policies. Building on previous studies,we refine and update the mitigation potentials for 20 land-based measures in >200 countries and five regions, comparing “bottom-up” sectoral estimates with integrated assessment models (IAMs).
The COVID-19 Pandemic is Intricately Linked to Biodiversity Loss and Ecosystem Health
The ongoing COVID-19 pandemic, caused by zoonotic SARS-CoV-2, has important links to biodiversity loss and ecosystem health. These links range from anthropogenic activities driving zoonotic disease emergence and extend to the pandemic affecting biodiversity conservation, environmental policy, ecosystem services, and multiple conservation facets. Crucially, such effects can exacerbate the initial drivers, resulting in feedback loops that are likely to promote future zoonotic disease outbreaks.
Preventing the Next Pandemic -- Zoonotic Disease and How to Break Chain of Transmission
This report is one of the first that specifically focuses on the environmental side of the zoonotic dimension of disease outbreaks during the COVID-19 pandemic. It tries to fill a critical knowledge gap and provide policymakers with a better understanding of the context and nature of potential future zoonotic disease outbreaks. It examines the root causes of the COVID-19 pandemic and other “zoonoses,” which the World Health Organization defines as human diseases or infections that are naturally transmissible from vertebrate animals to humans.
Amphibian Collapses Increased Malaria Incidence in Central America
Biodiversity in ecosystems plays an important role in supporting human welfare, including regulating the transmission of infectious diseases. This report leverages a unique ensemble of ecological surveys, satellite data, and newly digitized public health records to show an empirical link between a wave of Batrachochytrium dendrobatidis-driven collapse of amphibians in Costa Rica and Panama and increased human malaria incidence.
Roadmap for Achieving Net‑Zero Emissions in Global Food Systems by 2050
Food systems (FSs) emit about 20 billion tonnes of carbon dioxide equivalent per year (~ 35% of global greenhouse gas emissions). This level tends to raise given the expected increases in food demands, which may threaten global climate targets. This work provides options and a vision to guide global FSs to achieving net-zero by 2050.
Predicting the Potential for Zoonotic Transmission and Host Associations for Novel Viruses
Host-virus associations have co-evolved under ecological and evolutionary selection pressures that shape cross-species transmission and spillover to humans. Observed virus-host associations provide relevant context for newly discovered wildlife viruses to assess knowledge gaps in host-range and estimate pathways for potential human infection. Using models to predict virus-host networks, we predicted the likelihood of humans as hosts for 513 newly discovered viruses detected by large-scale wildlife surveillance at high-risk animal-human interfaces in Africa, Asia, and Latin America.
Extend Existing Food Safety Systems to the Global Wildlife Trade
This article discusses the suspected role of the wildlife trade in the COVID-19 pandemic and the risk of new emerging infectious diseases in humans have received widespread attention since the emergence of COVID-19. A range of measures to prevent future pandemics have been suggested, from a global ban of commercial trade in wildlife to bans of wild animals for human consumption.
Effectiveness and Profitability of Preventive Veterinary Interventions in Controlling Infectious Diseases of Ruminant Livestock in Sub-Saharan Africa: A Scoping Review
Agriculture in general, and livestock production in particular, serve as a livelihood source for many people in sub-Saharan Africa. In many settings, lack of control of infectious diseases hampers livestock productivity, under-mining the livelihood of rural populations. This scoping review sought to identify veterinary interventions previously evaluated as well as their relative effectiveness in controlling infectious livestock diseases.
Disease Control Tools to Secure Animal and Public Health in a Densely Populated World
Animal health is a prerequisite for global health, economic development, food security, food quality, and poverty reduction, while mitigating against climate change and biodiversity loss. This report details a qualitative review of 53 infectious diseases in terrestrial animals. It proposes and discusses five research priorities for animal health that will help to deliver a sustainable and healthy planet: vaccinology, antimicrobial resistance, climate mitigation and adaptation, digital health, and epidemic preparedness.
The Future of Fungi: Threats and Opportunities
The fungal kingdom represents an extraordinary diversity of organisms with profound impacts across animal, plant, and ecosystem health. With climate change, increased antimicrobial resistance, global trade, environmental degradation, and novel viruses altering the impact of fungi on health and disease, developing new approaches is now more crucial than ever to combat the threats posed by fungi and to harness their extraordinary potential for applications in human health, food supply, and environmental remediation. This report provides recommendations to accelerate fungal research and highlights major research advances.
Wildlife Susceptibility to Infectious Diseases at Global Scales
Disease transmission prediction across wildlife is crucial for risk assessment of emerging infectious diseases. Susceptibility of host species to pathogens is influenced by the geographic, environmental, and phylogenetic context of the specific system under study. This study uses machine learning to analyze how such variables influence pathogen incidence for multi-host pathogen assemblages.
Changing Food Systems and Infection Disease Risks in Low-Income and Middle-Income Countries
The emergence of COVID-19 has drawn the attention of health researchers sharply back to the role that food systems can play in generating human disease burden. But emerging pandemic threats are just one dimension of the complex relationship between agriculture and infectious disease, which is evolving rapidly, particularly in low-income and middle-income countries that are undergoing rapid food system transformation. This resource examines this changing relationship through four current disease issues.
Aligning Conservation and Public Health Goals to Tackle Unsustainable Trade of Mammals
Unsustainable wildlife trade is a major driver of biodiversity loss and an important public health threat. Yet, effective wildlife trade regulation is currently at odds with food security and economic incentives provided by this global, multibillion-dollar industry. Given such limitations, public health and conservation resources can be aligned to target species for which trade both increases risk of extinction and threatens public health. This study provides a preliminary step in prioritizing species, taxonomic groups, and countries for focused wildlife trade regulation to meet both conservation and public health goals.
Integrated Pest Management (IPM) and One Health - A Call for Action to Integrate
One Health (OH) has gained considerable prominence since the beginning of the 21st century, among others, driven by the recent epidemics and the increasing importance of zoonotic diseases but most emphasis has been on the interactions between animal and human health, with considerably less attention to environmental and plant health. There is growing evidence that the challenges of climate change, growing food and nutritional insecurity, and biodiversity loss can best be addressed within the context of the OH framework. Conceptionally, IPM could perfectly fit into such an approach. New approaches detailed in this report offer solutions on how to successfully embed IPM into a OH framework.
The Evolution of One Health: A Decade of Progress and Challenges for the Future
In the early years of the 21st century, emerging zoonotic viruses that had the potential to cause pandemic disease, including extensive human mortality, created several international crises (Gibbs 2005). Governments and scientists worldwide recognised that greater interdisciplinary collaboration was required to prevent and control zoonoses, and that such collaboration should include not only physicians and veterinarians, but also wildlife specialists, environmentalists, anthropologists, economists and sociologists, among others. The expression ‘One Health’ was proposed as a concept to foster such interdisciplinary collaboration.
Compendium of WHO and other UN Guidance on Health and Environment
The World Health Organization (WHO) and other United Nations (UN) organizations have published extensive guidance on a range of essential health topics over the years, specifically addressing disease, environmental pollutants, children’s health, among many other topics.
IPBES Workshop on Biodiversity and Pandemics
Pandemics represent an existential threat to the health and welfare of people across our planet. The scientific evidence reviewed in this report demonstrates that pandemics are becoming more frequent, driven by a continued rise in the underlying emerging disease events that spark them. Without preventative strategies, pandemics will emerge more often, spread more rapidly, kill more people, and affect the global economy with a more devastating impact than ever before.
A Comparison of Three Holistic Approaches to Health: One Health, EcoHealth, and Planetary Health
Several holistic and interdisciplinary approaches exist to safeguard health. Three of the most influential concepts at the moment, One Health, EcoHealth, and Planetary Health, are analyzed in this paper, revealing similarities and differences at the theoretical conceptual level. These approaches may appear synonymous, as they all promote the underlying assumption of humans and other animals sharing the same planet and the same environmental challenges, infections and infectious agents as well as other aspects of physical—and possibly mental—health. However, we would like to illuminate the differences between these three concepts or approaches, and how the choice of terms may, deliberately or involuntary, signal the focus, and underlying values of the approaches.
A Rapid Review of Evidence on Managing the Risk of Disease Emergence in Wildlife Trade
This synthesis integrates the lessons learned from each of the report’s chapters and highlights their implications for planning an OIE program on the wildlife trade and emerging infectious diseases. Each chapter includes an executive summary which supports this synthesis.
One Health and the Environment: From Conceptual Framework to Implementation Science
The insignia of several agencies dedicated to health and healing depict an animal, a snake, coiled around a potent staff. Various interpretations have been offered to explain the symbolic meaning of the Rod of Asclepius, but its representation of intertwined human health and animal health suggests a long history of relatively recent attempts, including the One Health framework, to define human health in the context of interconnectedness with other organisms.
Live and Wet Markets: Food Access versus the Risk of Disease Emergence
Emerging zoonotic diseases exert a significant burden on human health and have considerable socioeconomic impact worldwide. In Asia, live animals as well as animal products are commonly sold in informal markets. The interaction of humans, live domestic animals for sale, food products, and wild and scavenging animals, creates a risk for emerging infectious diseases. Such markets have been in the spotlight as sources of zoonotic viruses, for example, avian influenza viruses and coronaviruses, Here, we bring data together on the global impact of live and wet markets on the emergence of zoonotic diseases. We discuss how benefits can be maximized and risks minimized and conclude that current regulations should be implemented or revised, to mitigate the risk of new diseases emerging in the future.
How to Start Up a National Wildlife Health Surveillance Programme
A sound understanding of wildlife health is required to inform disease management and mitigation measures in order to help safeguard public, livestock, companion animal and wildlife health.
Ranking the Risk of Animal-to-Human Spillover for Newly Discovered Viruses
The death toll and economic loss resulting from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic are stark reminders that we are vulnerable to zoonotic viral threats. Strategies are needed to identify and characterize animal viruses that pose the greatest risk of spillover and spread in humans and inform public health interventions. Using expert opinion and scientific evidence, we identified host, viral, and environmental risk factors contributing to zoonotic virus spillover and spread in humans. We then developed a risk ranking framework and interactive web tool, SpillOver, that estimates a risk score for wildlife-origin viruses, creating a comparative risk assessment of viruses with uncharacterized zoonotic spillover potential alongside those already known to be zoonotic.
One Health Joint Plan of Action (2022-2026): Working Together for the Health of Humans, Animals, Plants and the Environment
The One Health Joint Plan of Action outlines the commitment of the four organizations – the Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Programme (UNEP), the World Organization for Animal Health (WOAH, founded as OIE), and the World Health Organization (WHO) – to collectively advocate and support the implementation of One Health. It builds on to existing global and regional One Health and coordination initiatives aimed at strengthening health systems at global, regional, and national level.
Effectiveness of Front Line and Emerging Fungal Disease Prevention and Control Interventions and Opportunities to Address Appropriate Eco-Sustainable Solutions

New alternative eco-solutions to address pathogenic fungi are needed, particularly in order to address fungi with increasing drug resistance where research and innovation can be enabled using a One Health approach.
One Health for All: Advancing Human and Ecosystem Health in Cities by Integrating an Environmental Justice Lens
The One Health concept provides an organizing framework that promotes the health and well-being of urban communities and ecosystems. However, for One Health to be successful, it must incorporate societal inequities in environmental disamenities, exposures, and policy. This is a review of the current literature on One Health perspectives, pinpoints areas in which to incorporate an environmental justice lens, and closes with recommendations for future work.
The Association Between Dengue Case and Climate: A Systematic Review and Meta-Analysis
Although previous research frequently indicates that climate factors impact dengue transmission, the results are inconsistent. Therefore, this systematic review and meta-analysis highlights and address the complex global health problems towards the human-environment interface and the inter-relationship between these variables.
Research and Innovation Opportunities to Improve Epidemiological Knowledge and Control of Environmentally Driven Zoonoses
While zoonotic diseases are defined by transmission processes between animals and humans, for many of these diseases the presence of a contaminated environmental source is the cause of transmission. Environmentally driven zoonoses (EDZs) are particularly challenging to diagnose and control as their reservoirs are in the natural environment and thus often escape conventional surveillance systems that rely on host monitoring. This review discusses the main challenges relating to the epidemiology, diagnosis, and control of EDZs.
One Health High-Level Expert Panel: One Health Theory of Change
The OHHLEP, established in May 2021, provides an advisory function to the Quadripartite organizations – FAO, UNEP, WHO and WOAH – to support their provision of evidence-based scientific and policy advice and technical support on One Health-related matters to their members. OHHLEP has developed an over-arching Theory of Change, designed to guide OHHLEP’s own work and that of the Quadripartite as well as providing a conceptual framework for other organizations, agencies, and initiatives working towards similar One Health goals.

Helping to Heal Nature and Ourselves Through Human-Rights-Based and Gender-Responsive One Health
The health of our planet and humanity is threatened by biodiversity loss, disease, and climate crises. The One Health approach is a pathway to addressing outcomes in term of health and sustainability, but gender issues are largely ignored. By examining the roles and responsibilities of Indigenous and Local People, and especially women, in conserving natural resources, the study shows that women bear a disproportionate health, poverty, and climate burden.
Climate Change Impacts on Plant Pathogens, Food Security, and Paths Forward
Plant disease outbreaks pose significant risks to global food security and environmental sustainability worldwide, and result in the loss of primary productivity and biodiversity that negatively impact the environmental and socio-economic conditions of affected regions. Climate change further increases outbreak risks by altering pathogen evolution and host–pathogen interactions and facilitating the emergence of new pathogenic strains.
Environmental Variation Across Multiple Spatial Scales and Temporal Lags Influences Hendra Virus Spillover
Pathogens can spill over and infect new host species by overcoming a series of ecological and biological barriers. Hendra virus circulates in Australian flying foxes and provides a data-rich study system for identifying environmental drivers underlying spillover events.
A Better Classification of Wet Markets is Key to Safeguarding Human Health and Biodiversity
Wet markets have been implicated in multiple zoonotic outbreaks, including COVID-19. They are also a conduit for legal and illegal trade in wildlife, which threatens thousands of species. Yet wet markets supply food to millions of people around the world, and differ drastically in their physical composition, the goods they sell, and the subsequent risks they pose. As such, policy makers need to know how to target their actions to efficiently safeguard human health and biodiversity without depriving people of ready access to food.
Intersectoral collaboration shaping One Health in the policy agenda_Ghana and India.pdf
Intersectoral collaborations are an integral component of the prevention and control of diseases in a complex health system. On the one hand, One Health (OH) is promoting the establishment of intersectoral collaborations for prevention at the human-animal-environment interface. On the other hand, operationalising OH can only be realized through intersectoral collaborations.
Opportunities for Transdisciplinary Science to Mitigate Biosecurity Risks from the Intersectionality of Illegal Wildlife Trade with Emerging Zoonotic Pathogens
Existing collaborations among public health practitioners, veterinarians, and ecologists do not sufficiently consider illegal wildlife trade in their surveillance, biosafety, and security (SB&S) efforts even though the risks to health and biodiversity from these threats are significant. We highlight multiple cases to illustrate the risks posed by existing gaps in understanding the intersectionality of the illegal wildlife trade and zoonotic disease transmission. We argue for more integrative science in support of decision-making using the One Health approach. Opportunities abound to apply transdisciplinary science to sustainable wildlife trade policy and programming, such as combining on-the-ground monitoring of health, environmental, and social conditions with an understanding of the operational and spatial dynamics of illicit wildlife trade.
Ecological Interventions to Prevent and Manage Zoonotic Pathogen Spillover
Spillover of a pathogen from a wildlife reservoir into a human or livestock host requires the pathogen to overcome a hierarchical series of barriers. Interventions aimed at one or more of these barriers may be able to prevent the occurrence of spillover. Here, we demonstrate how interventions that target the ecological context in which spillover occurs (i.e. ecological interventions) can complement conventional approaches like vaccination, treatment, disinfec- tion and chemical control. Accelerating spillover owing to environmental change requires effective, affordable, durable and scalable solutions that fully harness the complex processes involved in cross-species pathogen spillover.
Global Shifts in Mammalian Population Trends Reveal Key Predictors of Virus Spillover Risk
Emerging infectious diseases in humans are frequently caused by pathogens originating from animal hosts, and zoonotic disease outbreaks present a major challenge to global health. To investigate drivers of virus spillover, we evaluated the number of viruses mammalian species have shared with humans. We discovered that the number of zoonotic viruses detected in mammalian species scales positively with global species abundance, suggesting that virus transmission risk has been highest from animal species that have increased in abundance and even expanded their range by adapting to human-dominated landscapes. Domesticated species, primates, and bats were identified as having more zoonotic viruses than other species. Among threatened wildlife species, those with population reductions owing to exploitation and loss of habitat shared more viruses with humans. The exploitation of wildlife through hunting and trade facilitates close contact between wildlife and humans, and our findings provide further evidence that exploitation, as well as anthropogenic activities that have caused losses in wildlife habitat quality, have increased opportunities for animal-human interactions and facilitated zoonotic disease transmission. Our study provides new evidence for assessing spillover risk from mammalian species and highlights convergent processes whereby the causes of wildlife population declines have facilitated the transmission of animal viruses to humans.
Drivers of Antibiotic Resistance Transmission in Low-and Middle-Income Countries from a One Health Perspective - A Review
Antibiotic resistance is an ecosystem problem threatening the interrelated human-animal-environment health under the “One Health” framework. Resistant bacteria arising in one geographical area can spread via cross-reservoir transmission to other areas worldwide either by direct exposure or through the food chain and the environment. Drivers of antibiotic resistance are complex and multi-sectoral, particularly in Lower- and Middle-income countries. These include inappropriate socio-ecological behaviors; poverty; overcrowding; lack of surveillance systems; food supply chain safety issues; highly contaminated waste effluents; and loose rules and regulations.
Immediate Effects of the COVID-19 Pandemic on the Use of Wildlife as Food Among Indigenous People and Local Communities in South America

One Welfare Impacts of COVID-19 - A Summary of Key Highlights within the One Welfare Framework
One Welfare describes the interconnection between animal welfare, human wellbeing and their physical and social environment. The SARS-CoV-2 virus is the cause of COVID-19 and emerged as a human pathogen in 2019 although is thought to have a zoonotic source. The original wildlife reservoir and any potential intermediate hosts have not yet been identified. The combination of the virus zoonotic condition together with the impacts of disease control measures has exposed clear interconnections between animals, people and their environment from both a health and a welfare perspective.
The Security Threat that Binds Us: The Unraveling of Ecological and Natural Security and What the United States Can Do About It
Global ecological disruption is arguably the 21st Century’s most underappreciated security threat. Human societies are producing rapid, novel, and foundational changes across multiple Earth systems with concomitant—and sometimes severe—consequences for people, societies, and security worldwide. These changes are significant and globally consequential, and include the transformation of the atmosphere’s composition, overloaded and depleted soils, toxified and acidified oceans, and reconfigured freshwater systems.
Situation Analysis: COVID-19, Wildlife Trade, and Consumer Engagement
Despite evidence still being unclear as to the origins of the virus, people’s relationship with and consumption of wild animals such as pangolins has been irreversibly cast into sharp relief. Even if COVID-19 proves not to have originated from wild animals in trade, the COVID-19 pandemic has brought global attention to the growing number of wildlife-linked diseases emerging as major human health concerns - ranging from HIV to SARS, MERS, H1N1 (swine flu), H5N1 (avian flu) and Ebola. For many of these, there are strong indications of disease transmission links to wild animal trade.
The Impact of Climate Change on Health: Reducing Risks and Increasing Resilience in the Era of COVID-19
The climate crisis has many consequences – among them widespread health impacts that will lead to immense societal, ecological, and economic harm. Over the past two decades multiple large-scale reviews on climate change and health have made clear the need for a multi-sectoral approach to target the drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.

The Social Costs of Keystone Species Collapse: Evidence From The Decline of Vultures in India
Scientific evidence suggests the Earth is undergoing a mass extinction of species, caused by human activity. Evaluating the social costs of losing non-human species is necessary to manage biodiversity and target conservation resources. We show that the functional extinction of vultures in India increased human mortality because of a negative shock to sanitation.
Does Land‑use and Land Cover Affect Vector‑borne Diseases? A Systematic Review and Meta‑analysis
To evaluate the impact of land-use and land-cover (LULC) on the transmission of VBDs, we conducted a systematic review of the existing literature on the global effects of land use on VBDs. The systematic literature review revealed a temporal increase in publications on this topic, with a significant rise since 2007 and uneven distribution of data across countries, with the United States, Spain, and Brazil being the most prominent contributors and identified a wide range of pathogens and hosts involved in VBD systems, with human and avian malaria being the most commonly mentioned diseases.
Stratifying the Urban Matrix Using Zoning Laws: A Protocol for Bats and Their Pathogens
Urbanization implies important ecological changes in bat communities and in their intra and interspecific pathogen transmission. However, little is known about the influences of the urban components on the ecology and structuring of these communities. We used urban zoning to develop a sample design for an eco-epidemiological study of bats in São Paulo, the biggest Metropolitan Area of Brazil.

The Right to a Healthy Environment: Reconceptualizing Human Rights in the Face of Climate Change
There is hardly any doubt that climate change threatens the enjoyment of a wide range of human rights. Yet, in the absence of a distinct right to a healthy environment, a victim of climate change impacts would have to rely on existing rights to bring a claim. However, not only are these avenues not always successful or even sufficient to effectively and adequately compensate the victims, but they appear especially problematic in the context of climate change. This article explores the implications of the recognition of a stand-alone substantive right to a healthy environment in the context of climate change. In doing so, it argues that such a recognition could trigger a paradigm shift that would facilitate the reconceptualization of human rights law to better adapt to the negative impacts of climate change, in particular by incorporating key environmental law principles in the human rights system.
Opportunities and Challenges of Bio‐based Fertilizers Utilization for Improving Soil Health
Bio-based fertilizers (BBFs) have been promoted as a solution to help manage bio-waste problems and improve soil health conditions. This study found that contamination of heavy metals and pathogens is the main problem of BBFs implementation. Furthermore, compared to mineral fertilizers, BBFs have obstacles to getting social acceptance due to the challenges of transportation and production cost, the concentration of nutrients, matching crops, and policy framework.
Improving the Ecological and Economic Performance of Agri-environment Schemes: Payment by Modelled Results Versus Payment for Actions
Researchers and policy-makers have become increasingly interested in re-designing agri-environmental policy to improve both economic efficiency and ecological effectiveness. One idea within this debate has been payments for results (outcomes) rather than payment for actions. We compare payment for modelled results findings with approximately equivalent payment for actions schemes intended to deliver increases in the same biodiversity indicators.
The Effectiveness of Global Protected Areas for Climate Change Mitigation
Forests play a critical role in stabilizing Earth’s climate. Establishing protected areas (PAs) represents one approach to forest conservation, but PAs were rarely created to mitigate climate change. The global impact of PAs on the carbon cycle has not previously been quantified due to a lack of accurate global-scale carbon stock maps.
Pathogen Spillover Driven by Rapid Changes in Bat Ecology
During recent decades, pathogens that originated in bats have become an increasing public health concern. Our long-term study identifies the mechanistic connections between habitat loss, climate and increased spillover risk. It provides a framework for examining causes of bat virus spillover and for developing ecological countermeasures to prevent pandemics.

Plastic Pollution: How Can the Global Health Community Fight the Growing Problem?
Plastic products and plastic waste threaten human health because of their toxicity, role in disease propagation, possible interference with food supply through their environmental effects and socioeconomic impacts. Despite the burden caused by plastic pollution, the topic does not appear to be a priority on the agenda of the global public health community. International health organizations have not been vocal about plastic pollution as a health threat, and the issue is not frequently discussed in the global health scientific literature.
Overcoming Resistance: The Expert Panel on Antimicrobial Availability
This report focuses on one aspect of a comprehensive solution to the growing threat of Antimicrobial resistance — encouraging the development and commercialization of novel antimicrobials through pull incentives that offer enhanced financial returns to manufacturers bringing qualifying antimicrobials to the Canadian market and, more importantly, to patients in Canada.
A Review on the Fate, Human Health and Environmental Impacts, and Regulation of Antibiotics Used in Aquaculture
Antibiotics have been a necessary component of animal husbandry and aquaculture since they were first used in clinical settings in the 1940s to meet the rising demand for foods generated from animals. Because of this, large-scale industrial animal production has become a hotspot for the evolution and spread of ARGs (antibiotic resistant genes), potentially posing a threat to public health. This review is focused on human health hazards related to antibiotic usages, ARGs in cattle, and aquaculture systems.
Investigating Infectious Organisms of Public Health Concern Associated with Wild Meat
The wild meat trade poses a significant threat to public health as it facilitates the spillover of zoonotic pathogens through high-risk activities such as the hunting, butchering, trade, and consumption of wild animals. Despite the health risks and association with marking epidemics including SARS, Ebola, and COVID-19, the global wild meat trade continues to thrive. The diversity of infectious organisms associated with wild meat are highlighted through this review and could be used to guide policy development.

This study reports the deployment and results obtained from a nationwide IWM pilot test in eleven sites representing the habitat diversity of mainland Spain.
One Health and Neglected Tropical Diseases
One Health is defined as an approach to achieve better health outcomes for humans, animals, and the environment through collaborative and interdisciplinary efforts. Increasingly, the One Health framework is being applied to the management, control, and even elimination of neglected tropical diseases (NTDs). In this Special Issue, we present a diverse body of work united under the One Health ideology and a desire to mitigate the devastating effects of NTDs. The numerous diseases, methodologies, and landscapes presented highlight the interconnected and increasingly overlapping existence of humans, animals, and their pathogens.
Amazon Deforestation Drives Malaria Transmission, and Malaria Burden Reduces Forest Clearing
Deforestation and land use change are among the most pressing anthropogenic environmental impacts. In Brazil, a resurgence of malaria in recent decades paralleled rapid deforestation and settlement in the Amazon basin, yet evidence of a deforestation-driven increase in malaria remains equivocal. We hypothesize an underlying cause of this ambiguity is that deforestation and malaria influence each other in bidirectional causal relationships—deforestation increases malaria through ecological mechanisms and malaria reduces deforestation through socioeconomic mechanisms—and that the strength of these relationships depends on the stage of land use transformation.
