REGENERATIVE BLUE ECONOMY


Why in news :  The International Union for Conservation of Nature (IUCN) has released a report outlining a roadmap for a Regenerative Blue Economy (RBE).

About : 

What is the Regenerative Blue economy ?

  • A regenerative Blue Economy is an economic model that combines rigorous and effective regeneration and protection of the Ocean and marine and coastal ecosystems with sustainable, low, or no carbon economic activities, and fair prosperity for people and the planet, now and in the future

Significance of Regenerative Blue Economy for Global Sustainability 

  • Birodiversity Conservation:  Initiatives like marine protected areas (MPAs) not only safeguard habitats and species but also ensure the longevity of fisheries. Eg. Great Barrier Reef Marine Park suppots tourism and fisheries.
  • Climate Change Mitigation: Mangrove restoration and seaweed farming not only protect shorelines and improve water quality but also capture significant amounts of carbon dioxide. Eg. Projects like the Thor Heyerdahl Climate Park in Myanmar utilize mangrove reforestation to enhance carbon sinks, contributing to climate change mitigation.
  • Economic Diversification and Resilience: A regenerative blue economy promotes economic diversification by developing sustainable marine-based industries, such as renewable energy (wind, tidal), sustainable aquaculture, and ecotourism. Eg.  Development of offshore wind farms in countries like Denmark has created jobs while reducing reliance on fossil fuels.
  • Deep Sea Minerals :  Deep sea minerals, like manganese nodules and cobalt crusts, are vital for the Blue Economy. Eg. Papua New Guinea has explored deep sea mining in the Bismarck Sea, targeting mineral-rich hydrothermal vents to potentially enhance its Blue Economy
  • Pollution Reduction: Initiatives like the International Coastal Cleanup campaign mobilize global communities to tackle marine debris, thereby protecting marine life and enhancing the sustainability of ocean resources.
  • Sustainable Livelihoods:  In the Philippines, community-based projects that incorporate sustainable harvests of fish and other marine life have proven successful in both conserving biodiversity and enhancing local economies.

The Pillars of the Regenerative Blue Economy

  • Sustainable Marine Resource Utilization: Exploiting ocean resources (like fish and minerals) sustainably to ensure they remain available for future generations.
  • Marine Energy: Harnessing renewable energy from ocean sources such as tidal, wave, and wind power.
  • Aquaculture: Cultivating marine and freshwater biomass (like fish and algae) in a responsible manner to support food security and economic growth.
  • Maritime Transport and Logistics: Optimizing shipping routes and operations to reduce environmental impact and enhance efficiency.
  • Coastal Tourism: Developing eco-friendly coastal and maritime tourism that supports local economies without damaging ecosystems.
  • Waste Management: Implementing measures to reduce marine pollution by improving waste disposal and recycling processes in coastal and oceanic zones.
  • Ocean Governance: Establishing effective legal and policy frameworks to manage ocean resources and space equitably and sustainably.

Challenges and Limitations 

  • Economic and Infrastructure Limitations: Traditional maritime and shipping industries, which are significant contributors to the global economy, often involve high costs in modifying existing infrastructures to meet sustainable standards. Eg.The International Maritime Organization (IMO) estimates that reaching the 2050 greenhouse gas reduction targets could cost the shipping industry between $1 trillion to $1.4 trillion.
  • Technological Challenges: Technologies for efficient and sustainable aquaculture or energy generation from marine sources like tidal and wave energy are not universally accessible and can be cost-prohibitive. Eg. Global installed capacity of tidal energy is still below 535 MW, illustrating slow growth due to high installation and maintenance costs.
  • Social and Cultural Barriers: Transitioning to regenerative practices often requires substantial changes in local norms and practices, which can meet with resistance from local communities. Eg. In regions like the Caribbean, efforts to introduce lionfish as a food source to control its population and protect coral reefs have been hindered by local reluctance to change dietary preferences.
  • Environmental Degradation: Existing environmental damage, such as pollution, overfishing, and habitat destruction, complicates the implementation of regenerative practices.  Eg. The Great Barrier Reef,  has experienced severe bleaching events due to warming seas and pollution runoff, complicating conservation and restoration efforts.
  • Maritime Security : Maritime security poses a significant challenge to the Blue Economy, as piracy and illegal fishing threaten economic stability and resource sustainability. Eg. Somalia has faced severe disruptions in its maritime activities due to piracy in the Gulf of Aden.
  • Governance and Regulatory Frameworks:The United Nations has been working towards an international legally binding instrument under the UN Convention on the Law of the Sea (UNCLOS) to address these challenges and better manage marine biodiversity in areas beyond national jurisdiction.

CASE STUDY OF SUCCESS OF CHILE’S AQUACULTURE 

The development of Chile's aquaculture was driven by favorable government policies, investment in research and development, and the adoption of modern farming techniques. As a result, between 1990 and 2016, Chile's aquaculture sector saw considerable growth, with salmon production contributing significantly to the country's economy. However, the rapid growth of the aquaculture industry in Chile has not been without challenges, including environmental impacts such as water pollution and the spread of diseases.

Key Highlights of the report 

  • Proposed Hierarchy: The report outlines a structured framework to classify various sustainability levels within the Blue Economy model:
    • Ocean/Brown Economy: This level includes all economic activities related to the ocean that mirror traditional marine industries such as shipping and fisheries. The primary focus here is on economic prosperity.
    • Sustainable Blue Economy: This category integrates environmental sustainability and the protection of ecosystems. It goes beyond merely economic considerations to embrace conservation initiatives and the valuation of ecosystem services, in line with the UN Sustainable Development Goals.
    • Regenerative Blue Economy (RBE): This highest tier strives to actively restore and revitalize marine ecosystems. It merges intensive regeneration efforts with sustainable economic practices, fostering prosperity while addressing climate change and biodiversity loss.
  • Connections to Other Approaches: The report explores the connections between the Regenerative Blue Economy and various related concepts, including:
    • Circular Economy: It advocates for the Blue Economy to embrace circular economy principles, emphasizing the reduction of waste and promoting the reuse and recycling of resources in marine environments.
    • Bioeconomy: This involves utilizing marine-based biotechnology and biomass to foster a sustainable and regenerative economy within the Blue Economy framework.

News in Brief

EXPANDING GLACIAL LAKES IN INDIAN HIMALAYAS


Why in news : The Indian Space Research Organisation (ISRO) recently released a satellite-data-based analysis shedding light on the expansion of glacial lakes in the catchments of Indian Himalayan river basins. This analysis comes amidst growing concerns about the risks of glacial lake outburst floods (GLOFs).

About : 

Characteristics of Glacial lakes 

  • Size and Location: Glacial lakes vary in size, influenced by glacier size and activity, and are typically found in mountainous and polar regions with glaciers. 
  • Water Sources: Melting glacial ice, precipitation, and runoff are the primary water sources for glacial lakes. 

Significance: 

  • Water Regulation: Glacial lakes regulate water flow in glacier-fed rivers, crucial for maintaining water availability, especially during dry periods. 
  • Biodiversity: Glacial lakes support unique aquatic species adapted to cold, high-altitude environments. 
  • Landscape Formation: They contribute to landscape evolution and the creation of landforms like cirques and tarns. 

Ecological Challenges: 

  • Glacial Outburst Floods: Sudden water releases from glacial lakes, known as glacial lake outburst floods (GLOFs), pose significant risks to downstream communities and infrastructure, as seen in incidents like the Chamoli Disaster
  • Rapid Expansion: Increased glacier melting can lead to the rapid expansion of glacial lakes, raising the risk of flooding and landslides in surrounding areas 

Insights from ISRO's Analysis:

  • ISRO's analysis, which utilized satellite data spanning from 1984 to 2023, showed considerable growth in the size of glacial lakes across the Indian Himalayas. 
  • From the 2,431 lakes larger than 10 hectares recorded during 2016-17, 676 of these glacial lakes had significantly increased in size since 1984, with 601 lakes growing to over twice their original size. 
  • Notably, around 130 of these enlarged lakes are located in India, particularly within the river basins of the Indus, Ganga, and Brahmaputra, as a result of glaciers receding due to global warming.

1: Dimension- Risks and Challenges:

  • Glacial lakes are crucial as freshwater reservoirs for rivers, yet they also present significant risks, such as Glacial Lake Outburst Floods (GLOFs), which can cause rapid and devastating floods downstream.
  •  The difficult terrain of the Himalayas adds to the challenge of monitoring these lakes, making satellite remote-sensing an essential tool for thorough monitoring and risk assessment.

2: Dimension- Mitigation Strategies:

The National Disaster Management Authority (NDMA) has published guidelines for managing disasters related to GLOFs. These strategies include:

  • Identifying and mapping glacial lakes.
  • Utilizing Synthetic Aperture Radar imagery to detect changes in water bodies automatically, including the formation of new lakes during the monsoon season.
  • Developing methods for remote lake monitoring from space.
  • Structurally managing lakes to reduce their water volume through techniques such as controlled breaching, pumping, or siphoning out water, and constructing tunnels through moraine barriers or beneath ice dams.
  • Implementing solutions like using long High-Density Polyethylene (HDPE) pipes to siphon off water from lakes, which has been successfully employed to lower water levels in South Lhonak Lake in Sikkim.

Conclusion:      

Thus, the ISRO study sheds light on the evolving dynamics of Himalayan glacial lakes, emphasizing  the interaction  of climate change, glacier retreat, and the expansion of these lakes. It underscores the necessity of adopting a comprehensive approach encompassing scientific research, policy measures, and community engagement to safeguard the environmental stability of the region and mitigate risks to downstream human populations.
