Ecosystem disservices are the negative effects that natural systems can have on human well-being. They include things like crop pests, flooding, landslides, wildfire risk, invasive species, and disease transmission.
What the term means
The idea of ecosystem disservices was developed to complement the concept of ecosystem services. While ecosystem services describe the benefits nature provides, disservices focus on the harms or costs that can also arise from ecological processes.
This does not mean that nature is “bad.” It means that human and ecological systems interact in complex ways, and those interactions can produce both positive and negative outcomes.
Common examples
Some of the most discussed ecosystem disservices include agricultural pests, allergens, wildfire spread, flooding, zoonotic diseases, and damage caused by invasive species. In cities, examples can include messy fruit drop, aggressive birds, root damage to infrastructure, or mosquito breeding in poorly managed green areas.
These effects can vary by place and season, which is why disservices are often context-dependent rather than universal. A tree that provides shade and cooling in one setting may also create maintenance issues or allergies in another.
Why they matter
Ecosystem disservices matter because they influence how people perceive nature and how they support environmental policy. If negative impacts are ignored, projects may face public resistance or fail to deliver balanced outcomes.
They are especially relevant in urban planning, where green infrastructure is expected to provide many benefits but can also create trade-offs. Recognizing disservices helps planners design greener spaces that are safer, more functional, and better maintained.
Policy and research value
The concept is useful because it encourages a more realistic view of human-nature interactions. Researchers and policymakers can use it to identify risks, improve mitigation strategies, and avoid oversimplifying nature as always beneficial.
At the same time, some scholars argue that the term can be misleading if it suggests that nature itself is harmful rather than that certain ecological effects create costs for people. That debate shows why careful framing matters when discussing the social effects of ecosystems.
Why the concept is useful
Ecosystem disservices do not cancel out ecosystem services. Instead, they show that environmental management requires balance, context, and evidence.
In practice, this means planning for both benefits and risks. Healthy ecosystem management should aim to maximize services such as cooling, water regulation, and biodiversity while reducing harms such as pests, flooding, and disease exposure.
