Nature's Shield: How Trees and Forests Can Save Us From Disasters
"Discover the crucial role of forests in disaster risk reduction and mitigation, and how they can protect communities and ecosystems."
Disasters, as defined by the United Nations Office for Disaster Risk Reduction, represent severe disruptions to communities, leading to widespread losses that exceed local coping capacities. The increasing frequency and intensity of both natural and man-made disasters have resulted in significant casualties and property damage worldwide.
In 2015 alone, global disasters led to 22,773 deaths and affected 98.6 million people, with economic damages totaling USD 66.5 billion. Common natural disasters include floods, storms, droughts, landslides, earthquakes, tsunamis, wildfires, and extreme temperatures, highlighting the urgent need for effective disaster risk reduction strategies.
Nepal is highly vulnerable to various disasters, including earthquakes, floods, landslides, fires, avalanches, and glacial lake outburst floods (GLOFs). Annually, these disasters cause approximately 500 deaths and numerous injuries, with substantial property losses. The 2015 earthquake, one of the world's most significant natural disasters that year, caused immense human and economic impact, underscoring the critical importance of proactive disaster management.
Risk Reduction Before the Storm
Disaster risk reduction (DRR) aims to make communities stronger and better prepared, focusing on actions to reduce risk before a disaster occurs rather than on response and recovery after the event. The Sendai Framework for Disaster Risk Reduction 2015-2030 is an international agreement designed to strengthen disaster preparedness and thereby reduce disaster risk and losses. Supporting these efforts, the UN Office for Disaster Risk Reduction (UNDRR) provides frameworks and technical guidance for collecting and compiling disaster data, statistics, and indicators. Academic research on these questions is published in venues such as the International Journal of Disaster Risk Reduction.
Moving Beyond Narrow Mitigation
Risk mitigation, a long-standing element of the accepted approach, reduces the negative effects of threats such as cyberattacks and weather events on business continuity. However, recent discourse surrounding disaster risk reduction has increasingly emphasized the significance of local and historical perspectives, as illustrated by a Tunja, Colombia case study. Scholars also argue that a holistic approach focusing on vulnerability reduction, and on exploring the interdependencies and importance of critical infrastructures, is essential, underscoring the limitations of narrowly technical methods.
Stories, Platforms, and Milestones
On Simeulue Island, grandmothers have told and sung tsunami stories for over a hundred years, a tradition credited with saving lives and now studied as a transformative disaster risk reduction strategy. This oral practice predates modern disaster management institutions, which are described as the broader field within which formal DRR now operates. Formal milestones include national platforms, such as the third session of India's National Platform for Disaster Risk Reduction inaugurated in New Delhi, where global appreciation for the work of Indian rescue teams in Türkiye and Syria was noted. Together these examples show that disaster risk reduction draws on both ancient indigenous roots and modern institutional milestones.
The Role of Trees and Forests in Disaster Risk Reduction
Forests and trees play a vital role in mitigating the impact of natural disasters. They offer a natural defense against floods, landslides, and tsunamis by acting as physical barriers. This protection helps to prevent loss of life, property damage, and disruption of livelihoods. The conservation and management of forests provides a cost-effective and locally available means to protect communities from disasters.
- Physical Barrier: Forests act as a natural defense against floods, landslides, and tsunamis.
- Soil Stabilization: Tree roots reduce soil erosion and land degradation.
- Water Management: Forests enhance water storage and help prevent droughts.
- Building Material: Forests provide essential materials for shelter and infrastructure after disasters.
Gender Mainstreaming and Enduring Wisdom
Recent doctoral research investigates how women's needs can be mainstreamed into disaster risk reduction in the built environment, and the peer-reviewed findings emphasize the importance of gender mainstreaming. The same study, presented as a conference contribution, argues that gender considerations must be built into DRR practice rather than treated as peripheral. In parallel, researchers are studying how grandmothers' telling and singing of tsunami stories on Simeulue Island has functioned as a transformative disaster risk reduction strategy credited with saving lives for over a hundred years.
The Failure of Relief-Centric Spending
A recurring critique is that disaster-related expenditure remains largely relief-centric, with comparatively lower emphasis on mitigation and risk reduction measures that are essential for reducing long-term disaster losses. The ODI argues that to reduce the impact of disaster risk, root causes must be addressed, combining the expertise of sociologists, emergency service professionals, and development experts. Within this debate, risk mitigation remains defined as a key step in the risk management process, involving the planning and development of options to reduce the threats faced by businesses.
Front-Line Response and Inclusive Risk
Because police and other emergency services sit on the front line of responses to major disasters, comparative analysis of major incidents offers significant potential to reduce risk and improve preparedness. Complementing this institutional lens, research on global flood risk argues for a more inclusive understanding of disaster risk reduction, examining how coastal flooding and its DRR measures affect sexual and gender minorities. Taken together, the two perspectives suggest that effective analysis must compare both organizational responses and the experiences of often-marginalized affected populations.
Call to Action: Protecting Our Forests for a Safer Future
To fully leverage the protective capabilities of trees and forests, it is essential to integrate forest management into broader disaster risk reduction strategies. This includes promoting community-based forest management, ensuring emergency provisions for wood supply during disasters, and developing comprehensive emergency response plans within the forestry sector. Further research is needed to fully understand the role and effectiveness of trees and forests in preventing and mitigating various types of disasters, ensuring a safer and more resilient future for communities worldwide.
A Call for Prevention Over Recovery
Experts increasingly argue that prevention must take priority over response. Writing on the KZN floods, Livhuwani Nemakonde urged that government, supported by civil society and the private sector, direct efforts toward disaster risk reduction rather than spending billions on response and recovery. UN Secretary-General António Guterres has likewise stressed that disaster risk is not the sole responsibility of local and national authorities, warning that bad situations only get worse without disaster risk governance and calling for political commitment at the highest level to deliver on the SDGs and the Sendai Framework. ESCAP's expert commentary on mangrove risks ties such warnings to climate signals, drawing on voices including the Maldivian Red Crescent.
A Greener and More Prepared Horizon
The future of disaster risk reduction is likely to hinge less on any single technology and more on how well nature and communities are woven into governance systems. As awareness of cascading and slow-onset risks grows, expectations are rising that forward-looking frameworks will give greater weight to preparedness and prevention, though the precise shape of these frameworks remains uncertain. Progress will depend on sustained political commitment and adequate investment, making the outlook one of cautious optimism rather than certainty.
Slow and Cascading Risks
Disasters are increasingly understood as systemic and cascading rather than isolated events. The COVID-19 pandemic exposed this reality in low-income, multi-hazard contexts such as Malawi, where pre-existing vulnerabilities amplified impacts across health, economic, and social systems. Slow-onset disasters pose an equally difficult challenge: as UN Special Representative Margareta Wahlström observed, at first glance one would expect that the slower the onset of a disaster, the better prepared communities should be to mitigate its impacts. These patterns point to systemic challenges that demand coordinated action across multiple sectors.
People on the Front Line
Research on Mozambique shows that integrating nature-based solutions into flood management reduces damages and costs while increasing community resilience and providing ecosystem services that extend beyond flood risk reduction. The human element is equally decisive: a Bangladesh case study describes how women protect houses from strong wind and flooding, provide food and fuel after a disaster, and cover tubewells with plastic to prevent saline water intrusion. Institutional engagement, however, does not always keep pace, with research on 2024 Scottish flood-related media coverage highlighting reactive institutional community engagement in place-based policy implementation.
