Thee Role of Forest and d Wetlands in Mitygating Klimat Impacts Change

Forest andd wetlands are among the most powerful natural systems for slowing te e pace of climate change. They absorb vast compats of carbon dioxide, regulate local andd global weather paracarts, and shield communities from floods ande erosion.

Understanding Carbon Sequestration in Forests andWetlands
Carbon sequestration - thee process of capturing andd storing atmosferic carbon dioxide - is the most widely regardezed climate services provided by forests andd wetlands. Both ecosystems lock way carbon for decades, centeries, or even millennia, preventing im from contribution tam thee greenhouse effect.
Forest as Carbon Sinks
Trees absorb CO Řduring photosyntesites andstore carbon in their trunks, branches, leafes, and roots. Old- growth forest are especially y valuable; their mature tree hold massive contacts of carbon, and their complex canope continue to acculate carbon over long timescales.

Deforestation reverses the benefit. When forests are burned or cleared, thee store d carbon is released back into the atmosfere, accounting for roughly 10- 15% of global antropogenic emissions. Protecting existing forests is rethefore more effective than planting new one, because mature ecosystems have already acculated decades of carbon.
Wetlands as Long- Term Carbon Stores
Though often overlooked, wetlands are among thee mott carbon- rich ecosystems on Earth. Peatlands, mangroves, seagraps beds, and freshathers marshes accumulate organic matter in waterlogged, oksygen- poor soils that slow decoposition. Peatlands cover only 3% of thee term 's land are a but store controlle 30% of all soil carbon - twice as much as all thee end' s forests.

When wetlands are drained, draind for agricultura or development, thee store d carbon oxidizes and is released as CO kona. peath d degradation alone emits an estimated 2 billion metric tons of CO continually. Preciving and rewetting these landscapes is resufé a cost- effective climate compation strategy.
Climate Regulation: Local and Global Impacts
Beyond carbohn storage, forests andd wetlands help regulate temperatures andd rainfall Patterns, both locally andd globully.

This effect can reduce surface temperatures by 3-5 ° C in forested areas compared to adjacent cleared land.

Forest Root Systems andSoil Stabilization

When forests are cleared, erosion rates can increase by 10- 100 times, leading to landslides, silted rivers, and damaged ecosystems. Reforesting degraded hillside is a proven technique for recuring soil stability and reducing disaster risk.
