ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Blue carbon ecosystems, such as mangroves, salt marshes, and seagrasses, are capable of sequestering carbon from the atmosphere and storing it in their biomass and soil.

Statement 2 is correct: The Blue Carbon Initiative is the first integrated program focused on mitigating climate change by conserving, restoring, and promoting sustainable use of coastal marine ecosystems globally. The Initiative currently focuses on mangroves, tidal marshes and seagrasses. This program facilitates work with partners from national governments, research institutions, NGOs, coastal communities, intergovernmental and international bodies and other relevant stakeholders.

Statement 3 is not correct: Although green carbon ecosystems such as tropical rainforests are well known for their carbon sequestration abilities, blue carbon ecosystems are in fact even more effective at capturing and storing carbon. Unlike &ldquo;green carbon&rdquo; rainforests, which store carbon in biomass, and therefore release it when the trees die, mangroves & seagrass store most of the carbon in their soil and sediment. Blue carbon ecosystems not only store carbon for a millennia (if undisturbed), they also capture carbon approximately 40 - 50x faster.
