Brazil’s Amazonian Mangroves: Crucial for Climate Change Mitigation

Brazil’s Amazonian Mangroves: Crucial for Climate Change Mitigation

Brazil’s Amazon is home not only to the world’s largest tropical forest, but also one of the world’s largest mangrove areas. Mangroves are collections of different tree and shrub species found in tropical coastal regions, growing in waterlogged soils. They can be recognized because of  their large roots protruding from soils—roots they use to ‘anchor’themselves from strong incoming tides. There are over 80 distinct mangrove tree species, and can sequester or store large amount of carbon in their soils, which can be stored for multiple centuries. Deforestation of mangroves results in the release of sequestered carbon dioxide, as trees, plants, and soils release stored carbon once they are logged and cleared or burned. Although mangroves represent only 0.6% of global tropical forests, a new, long-term study published in the journal Biology Letters shows that these mangrove forests contain much more stored carbon than previously thought, and that their deforestation accounts for as much as 12 percent of greenhouse gas emissions produced by all tropical deforestation worldwide.

Is Climate Change a Security Issue?

Is Climate Change a Security Issue?

There is a significant yet still under-researched connection between climate change and security-related risks. The frequency of extreme weather events, including flooding, severe droughts and other associated impacts of global warming are contributing to the reduction of crop yields, diminishing water resources, and ultimately impacting human livelihood. In some cases, these events have contributed to the migration of ‘climate refugees’ in order to meet their basic human needs, including access to water, food, electricity, and shelter. As a result, climate change is increasingly entering the policy arena as a significant security issue.
