General Studies Paper-3
Context: France and Brazil launched a landmark international initiative Blue Nationally Determined Contributions (NDC) Challenge.
About Blue Nationally Determined Contributions (NDC) Challenge
- It urges countries to embed ocean-centric actions into their climate plans, known as Nationally Determined Contributions (NDCs).
- The challenge aims to dramatically scale up ocean-focused climate action ahead of the 30th Conference of Parties (COP30) to the United Nations Framework Convention on Climate Change (UNFCCC) in Belem, Brazil.
- The initiative is supported by various organizations like Ocean Conservancy, the Ocean & Climate Platform, the World Resources Institute (through the Ocean Resilience and Climate Alliance – ORCA), and WWF-Brazil.
Significance of Oceans in Climate Action
- Carbon Sequestration: Oceans absorb over 25% of global COâ‚‚ emissions and 90% of excess heat generated by human activity, making them critical in mitigating climate change.
- Blue Carbon Ecosystems: Coastal ecosystems like mangroves, seagrasses, and salt marshes store carbon at a rate up to five times higher than terrestrial forests.
- Biodiversity: Oceans are home to a vast diversity of life forms, and protecting marine ecosystems is essential for maintaining biodiversity, which in turn ensures the resilience of the ecosystem to climate impacts.
- Livelihood and Food Security: Oceans support over 3 billion people worldwide who depend on marine resources for food, livelihoods, and economic activities.
Initiatives for Ocean Conservation
- Ocean Cleanup Project: Launched in 2013, The Ocean Cleanup is a non-profit organization focused on developing advanced technologies to remove plastic pollution from the ocean.
- United Nations Decade of Ocean Science for Sustainable Development (2021-2030): Aims to promote ocean science as a key tool for sustainable development, environmental protection, and climate action.
- High Seas Treaty (Agreement on Biodiversity Beyond National Jurisdiction – BBNJ Agreement): Adopted in 2023, this landmark legally binding agreement aims to protect marine biodiversity in international waters.
- Blue Carbon Initiatives: It refers to the carbon captured by coastal and marine ecosystems such as mangroves, seagrasses, and salt marshes.
- National Marine Protected Areas (MPAs) Network: It aims to conserve critical marine and coastal habitats like coral reefs, mangroves, and seagrasses.
- Integrated Coastal Zone Management (ICZM): To address the challenges of coastal ecosystem degradation, including erosion, overfishing, and pollution.
Challenges and Barriers
- Financial Constraints: Many developing nations may struggle to secure the necessary funding to implement ocean-based climate solutions.
- Technical and Scientific Challenges: Ocean-based solutions are complex and require sophisticated scientific knowledge to implement effectively.
