What is a wetland?

Back

A wetland is a land area that is saturated with water, either permanently or seasonally, where oxygen-free processes prevail. Wetlands are crucial for biodiversity, water purification, and flood control.

Front

Why are wetlands important?

Back

Wetlands provide essential ecosystem services, including habitat for wildlife, water filtration, flood protection, and carbon storage.

Front

What are the main types of wetlands?

Back

The main types of wetlands include marshes, swamps, bogs, and fens, each characterized by different vegetation and hydrology.

Front

What is wetland habitat loss?

Back

Wetland habitat loss refers to the degradation or destruction of wetland areas due to human activities such as urban development, agriculture, and pollution.

Front

What are the causes of wetland loss?

Back

The primary causes of wetland loss include drainage for agriculture, urbanization, pollution, and climate change.

Front

How does wetland loss affect biodiversity?

Back

Wetland loss leads to a decline in biodiversity as many species depend on wetlands for habitat, food, and breeding.

Front

What role do wetlands play in flood control?

Back

Wetlands act as natural sponges, absorbing excess rainwater and reducing the risk of flooding in surrounding areas.

Front

What is the significance of wetland restoration?

Back

Wetland restoration aims to return degraded wetlands to their natural state, improving biodiversity, water quality, and ecosystem services.

Front

How do wetlands contribute to water quality?

Back

Wetlands filter pollutants from water, trapping sediments and breaking down harmful substances, thus improving overall water quality.

Front

What is the impact of climate change on wetlands?

Back

Climate change can alter hydrology, increase salinity, and lead to more frequent flooding or droughts, threatening wetland ecosystems.
