Understanding the Ecosystem Services of Riparian Forests: Patterns, Gaps, and Global Trends

Abstract

Riparian forests are usually situated between terrestrial and aquatic systems. They play an essential role in the health of the environment and in providing complex ecosystem services. This is especially essential in arid and semi-arid regions. However, despite these facts, riparian ecosystems are underexplored in the specialty literature. As such, the purpose of this study is to address this gap by synthesizing the current knowledge about riparian forests, using both a bibliometric analysis and a qualitative literature approach. This analysis allowed us to identify six main ecosystem services provided by riparian forests: biodiversity support, carbon sequestration, water quality regulation, slope stability, pollution mitigation, and sociocultural benefits. Furthermore, we have emphasized local challenges (deforestation, agricultural expansion, a lack of policies). Connecting ecological knowledge with a socio-cultural context is the first step in creating a strong foundation for the adequate management of these essential ecosystems, while also supporting their conservation, development and climate resilience.
