Assessment of forest ecosystem service research trends and methodological approaches at global level: a meta-analysis

201995 citationsOpen access

In plain language

Research into ecosystem services has expanded substantially, yet forest ecosystem services represent only a modest fraction of the broader literature. An assessment of 41 peer-reviewed studies examining forest ecosystem services reveals that scholarly attention concentrates predominantly on timber production, water supply, carbon sequestration, and recreation. Conversely, vital services such as pollination, genetic resources, pest regulation, and aesthetic values remain unaddressed in the reviewed literature. Methodological approaches across the analysed studies vary widely, resulting in fragmented and inconsistent findings. Geographically, most investigations have taken place in Europe and Asia, whilst African representation is notably scarce, with very few studies originating from Ethiopia. This geographical and thematic imbalance highlights an urgent need for more comprehensive, standardised research in regions experiencing ongoing forest degradation.

Key takeaways

  • Global research on forest ecosystem services remains limited despite an overall surge in ecosystem service literature.
  • Existing studies concentrate heavily on timber, water supply, carbon sequestration, and recreation, neglecting services such as pollination and pest regulation.
  • Research methods vary substantially across the literature, yielding inconsistent and fragmented conclusions.
  • Most published studies originate from Europe and Asia, leaving nations such as Ethiopia critically under-represented.

Why it matters

Forests deliver critical ecological and economic benefits, yet current scientific understanding remains skewed towards select geographical zones and specific commercial goods. Highlighting these gaps ensures that environmental policymakers and resource managers recognise under-researched ecosystem benefits, such as pest regulation and genetic diversity. This awareness is particularly vital for developing regions where forest loss threatens livelihoods before local ecological dynamics are properly documented.

Commercialisation angle

The abstract does not indicate an application pathway, as it focuses exclusively on reviewing academic literature trends and methodological gaps in forest ecosystem service research.

Abstract

Ecosystem service (ES) is a growing field of research characterized by an increase in publication number. The review was conducted to provide an overview of trends of forest ecosystem services (FES) research and methodological approach to studied FES. Currently, the number of publications on ES was more than 18,000, but small publications were linked with FES. Based on the selection criteria, 41 peer-reviewed publications were screened to analyze the type of FES studied and the method used to quantify ES. The result showed that most of the research articles, to date, had focused largely on provisioning, regulating and cultural ecosystem services, which were timber production, water supply, carbon sequestration, and recreation. FES like a pollination, genetic resources, pest regulation, and aesthetic values have not been studied in any literature reviews. The review result showed that different studies used diverse methodological approaches and had inconsistent and scattered conclusions. From the selected studies, the majority of them were conducted in Europe and Asia. Particularly, the publication number from Ethiopia was very low and needs to conduct studies before the forest resources are further degraded.
