With climate change driving an increase in the frequency and intensity of hevy rainfall events, urban flooding poses a growing risk to infrastructures, human safety, and concuritty. Urban wetlands act as natural detention and retention basins that slow w down runoff, absorb excess water, and recorase it gradually, thereby reducing peak foud volumes and compatiating fload damage.

Beyond flood control, wetlands faciliate groundwater recharge by allowing water to infiltrate soils, contracting the impermeable surfaces creatd by urban development such as concrete and asfalt.

Wyzwania to Wetland Conservation in Urban Areas

Habitat Loss and Fragmentation from Development

Te moszt pressing to urban wetlands is direct habitat loss caused by land conversion for housing, transportion networks, industrial sites, and commercial development. Wetlands are often perceived as low- value or problematic lands, leading to drainage, filliing, or paving over with out tiod for their ecological functions.

Every n when wetlands are reserved, fragmentene caused by roads, buildings, and tell infrastructure isolates wetland patches, impeding wildlife movement andgene flow. Fragmented wetlands lose ecological difficience ande mate more snherable to environmental stressors. Development paractes that diseared wetland functions create long-term liabilities such as pregloud risk, degraded water quality, and loss of biodiversity.

Pollution andHydrological Alteration

Urban runoff wprowadza kompleksowe mieszalniki zanieczyszczeń, w tym ding road salts, difficides, appeeuticals, microplastics, and heavy metals. Over time, these difficiants accumulate in wetland soils and vegetation, exceeding the system 's natural filtration capacity and leading to ecosystem degradation.

Hydrological distorsions such as channelization of streams, installation of stormwater pipes, and impervious surface explosion alter natural water flow regimes. Some wetlands experimence water designation, while others are subieted to unnatural surges or prolonged fooding, both of which can harm nativa vestigation and aquatic fauna.
