The concept of ecosystem services has gained prominence in environmental policy, yet its economic valuation remains contentious. Proponents argue that assigning monetary values to services such as pollination or water purification enables cost-benefit analysis, guiding efficient resource allocation. Critics, however, contend that this approach commodifies nature, reducing complex ecological processes to market terms and potentially undervaluing intrinsic or non-use values. Furthermore, valuation methods often rely on hypothetical scenarios, leading to estimates that vary widely depending on assumptions. Despite these debates, many governments now incorporate ecosystem service assessments into land-use planning, suggesting a pragmatic acceptance of the framework, albeit with ongoing refinements to address ethical and methodological concerns.
