A Review of Wetlands and the Hydrological Cycle: Key Players in Water Regulation and Ecosystem Health

Wetlands play a crucial role in the global hydrological cycle, acting as vital ecosystems that regulate water flow, enhance water quality, and provide essential habitat for diverse flora and fauna. This review synthesizes current knowledge on the functions and services of wetlands, emphasizing their importance in water regulation and ecosystem health. We explore the mechanisms through which wetlands contribute to groundwater recharge, flood mitigation, and nutrient cycling, while also addressing the impact of human activities and climate change on these critical environments. Furthermore, we discuss management strategies and conservation efforts aimed at preserving wetland ecosystems, highlighting the need for integrated approaches that recognize their multifunctional benefits. By understanding the pivotal role of wetlands, we can better advocate for their protection and sustainable management in the face of on-going environmental challenges.
