1. Definition and Scope

EcoHealth is an interdisciplinary field focused on the complex relationships between ecosystems, human health, and animal health. It integrates ecological, social, and biomedical sciences to address health challenges emerging from environmental change, biodiversity loss, and human-animal-environment interactions.

  • Core Concepts:
    • One Health approach
    • Socio-ecological systems
    • Disease ecology
    • Environmental determinants of health

2. Historical Development

  • Origins (Late 20th Century):

    • Emerged from growing awareness of zoonotic diseases and environmental degradation.
    • Influenced by the 1992 Rio Earth Summit and the Convention on Biological Diversity.
    • Early focus on tropical diseases, vector ecology, and the impact of land-use change.

  • Key Milestones:

    • 2003: SARS outbreak highlighted the need for integrated health approaches.
    • 2004: Launch of the EcoHealth Alliance, fostering global collaboration.
    • 2008: The journal EcoHealth established, providing a dedicated platform for research.

  • Integration with One Health:

    • EcoHealth and One Health share goals but EcoHealth emphasizes ecosystem processes and socio-political contexts.

3. Key Experiments and Studies

3.1. Nipah Virus Emergence (Malaysia, 1998-1999)

  • Observation: Outbreak linked to pig farms near fruit bat habitats.
  • Findings: Deforestation and agricultural expansion increased bat-pig-human contact.
  • Impact: Demonstrated how environmental change can drive zoonotic spillover.

3.2. Lyme Disease and Biodiversity (USA, 2000s)

  • Experiment: Manipulation of small mammal diversity in forest plots.
  • Result: Higher biodiversity reduced Lyme disease risk by diluting competent hosts.
  • Conclusion: Biodiversity loss can increase human disease risk.

3.3. COVID-19 Pandemic (Global, 2020–)

  • Research Focus: Wildlife trade, land-use change, and viral emergence.
  • Recent Study: Carlson et al. (2022) in Nature modeled how climate change is shifting the geographic overlap of mammal species, increasing viral sharing and spillover risk.

3.4. Bioluminescent Organisms and Ocean Health

  • Observation: Bioluminescent plankton (e.g., dinoflagellates) create glowing waves.
  • EcoHealth Insight: Bioluminescence patterns serve as indicators of ocean health, nutrient levels, and ecosystem disturbance.

4. Modern Applications

  • Disease Surveillance: Integrating ecological data with public health monitoring to predict outbreaks (e.g., malaria, Ebola).
  • Climate Change Adaptation: Assessing how shifting habitats and weather patterns affect disease vectors and food security.
  • Urban EcoHealth: Studying green spaces, air quality, and urban biodiversity impacts on mental and physical health.
  • Policy Development: Informing land-use planning, wildlife trade regulation, and conservation strategies.
  • Community Engagement: Participatory research with local populations to co-design interventions.

5. Controversies

  • Data Sharing and Sovereignty: Disputes over pathogen samples and genetic data, especially between Global North and South.
  • Wildlife Trade Bans: Debates on effectiveness versus impact on local livelihoods.
  • EcoHealth Alliance Funding: Scrutiny over research funding, especially regarding high-risk pathogen studies.
  • Interdisciplinary Challenges: Difficulty integrating ecological, social, and biomedical data due to differing methodologies.
  • Ethical Concerns: Balancing disease prevention with conservation and human rights.

6. Project Idea

Title: “Mapping Bioluminescent Hotspots as Indicators of Coastal Ecosystem Health”

  • Objective: Use satellite and in-situ data to map bioluminescent events and correlate them with water quality, pollution, and biodiversity metrics.
  • Methods: Field sampling, remote sensing, and citizen science data collection.
  • Expected Outcomes: Identify early warning signs of ecosystem stress and inform coastal management.

7. Most Surprising Aspect

The use of bioluminescent organisms as real-time, natural biosensors for ocean health is a rapidly advancing field. These organisms respond visibly to changes in water chemistry, pollution, and physical disturbance, providing a unique, non-invasive method for monitoring ecosystem changes that is both accessible and scalable.

8. Recent Research Example

  • Carlson, C.J., Albery, G.F., et al. (2022). “Climate change increases cross-species viral transmission risk.” Nature, 607(7919), 555–562.
    This study used predictive modeling to show that climate-driven range shifts in mammals will dramatically increase the risk of novel viral sharing events, underlining the importance of EcoHealth approaches in pandemic prevention.

9. Summary

EcoHealth is a dynamic, interdisciplinary field addressing the interconnectedness of environmental, animal, and human health. Its history is rooted in recognizing the ecological drivers of disease and environmental change. Key experiments have demonstrated the impact of biodiversity, land use, and climate on disease emergence. Modern applications span disease surveillance, climate adaptation, and policy development, while the field faces ongoing controversies related to data, ethics, and interdisciplinary integration. The surprising utility of bioluminescent organisms as ecosystem health indicators exemplifies EcoHealth’s innovative approaches. Recent research highlights the urgent need for EcoHealth perspectives in addressing global health threats.
