When people think about the threats facing humanity’s shared history, they often picture dramatic forces: earthquakes, floods, war, or fire. These dangers are real, and global institutions rightly mobilize to respond to them. But there is another threat that is far quieter, far less visible, and just as destructive if left unchecked: pests.
Recent efforts highlighted through UNESCO’s Memory of the World Initiative underscore how fragile our documentary heritage truly is. From earthquake-damaged manuscripts in Nepal to centuries-old woodblocks in Vietnam deteriorating from fungal growth, the risks to cultural memory are global and growing. Among the most alarming examples is the discovery of termite damage in historic church manuscripts in Malawi, documents dating back to the late 1800s that help tell the story of a nation’s people, faith, and social development.
Termites do not make headlines. They do not arrive with sirens or satellite images. Yet they are capable of erasing centuries of history in a matter of months and years. Unlike floods or fires, their destruction often goes unnoticed until it is irreversible. By the time visible damage appears, irreplaceable records may already be lost.
This reality exposes a critical truth: preservation is not only about digitization, training, or emergency response plans. It is about prevention.
You cannot preserve what has already been consumed. Digitization efforts, while essential, depend on the physical survival of original materials. Disaster management plans are only effective if the underlying threats are controlled. In many cases, that means confronting biological risks head-on.
The work underway in Malawi illustrates this point clearly. Conservation experts identified termite activity as a primary driver of deterioration. The response was not ideological or abstract. It was practical. Professionals developed a disaster management plan and established a dedicated repository designed to protect these manuscripts for the long term. This kind of intervention recognizes that safeguarding history requires real-world solutions grounded in science, not avoidance.
Pest management in cultural preservation is often misunderstood because it is mistakenly framed as a choice between environmental responsibility and protection. In reality, modern pest control operates under strict regulatory oversight and emphasizes targeted, precise application by trained professionals. These tools are designed to minimize exposure while maximizing effectiveness. When used responsibly, they are far less disruptive than repeated reconstruction, loss, or emergency salvage efforts after damage has occurred.
There is also an equity dimension to this issue. Many of the regions most affected by documentary heritage loss are Small Island Developing States and Least Developed Countries. These communities often lack the resources to recover from preventable damage. When historic records are destroyed, it is not just paper that disappears. Languages, traditions, and identities vanish with them. Denying proven protective tools in the name of ideological purity disproportionately harms those who can least afford the loss.
Global preservation initiatives increasingly acknowledge that cultural heritage faces multiple, overlapping threats. Climate change, conflict, natural disasters, and biological deterioration all demand serious attention. Addressing only some of these risks while ignoring others leaves preservation efforts incomplete.
Protecting humanity’s memory means confronting uncomfortable realities. Silent threats still destroy. Science still matters. And responsible intervention remains essential. If we are serious about preserving the world’s documentary heritage for future generations, we must be willing to use every proven, carefully managed tool available to stop destruction before it starts.
