Nature

Dredging and the placement of dredged material has been shown to cause adverse environmental effects on aquatic environments including seasonal wetlands.

Background

A wetland which is only wet during a part of the year, typically winter.

Incidence

Seasonal wetland habitats are experiencing alarming rates of decline globally, with an estimated 64% loss since 1900, according to the Ramsar Convention. These habitats, vital for biodiversity, water purification, and flood control, are threatened by agricultural expansion, urbanization, and climate change. The loss is particularly acute in Asia, Africa, and South America, where wetlands are rapidly converted for development, resulting in significant ecological and socio-economic impacts.
In 2022, the Pantanal wetland in Brazil, the world’s largest tropical wetland, suffered severe degradation due to unprecedented drought and extensive wildfires. Over 30% of its area was affected, endangering countless species and local livelihoods.

Claim

The destruction of seasonal wetland habitats is an urgent crisis that demands immediate action. These unique ecosystems support countless species, regulate floods, and purify water, yet they are vanishing at an alarming rate due to human negligence. Ignoring their loss is reckless and short-sighted, threatening biodiversity and our own well-being. Protecting seasonal wetlands is not optional—it is a moral and environmental imperative that we cannot afford to ignore any longer.

Counter-claim

The concern over threatened seasonal wetland habitats is vastly overstated. These areas naturally fluctuate and recover over time, making their so-called “threatened” status questionable. Resources and attention should be directed toward more pressing global issues like poverty, healthcare, and education. Focusing on seasonal wetlands diverts energy from real problems that directly impact human well-being. In the grand scheme, their loss is not a significant concern and does not warrant urgent action.
