A critically endangered Great Indian Bustard (GIB) chick was successfully born through artificial insemination (AI) at a breeding center in Jaisalmer, Rajasthan, marking a crucial step in efforts to save the species.

Endangered Status:

• The Great Indian Bustard is classified as critically endangered with fewer than 150 individuals left in the wild in India.
• About 90% of these birds are found in the desert areas of Rajasthan, with smaller populations in Gujarat, Maharashtra, Andhra Pradesh, and Karnataka.

Main Threats to the Species:

• Habitat Loss: The primary threat is the loss of habitat, which is often perceived as wasteland and is diverted for infrastructure projects like roads and development.
• Slow Reproductive Rate: The bustard’s low reproductive rate exacerbates its risk of extinction.

Conservation Efforts: Bustard Recovery Program

• In 2016, the Union Ministry of Environment, Forests and Climate Change launched the Bustard Recovery Program to focus on captive breeding and creating a sustainable environment for the reintroduction of GIBs into the wild.
• A dedicated GIB breeding center was set up at the Desert National Park in Jaisalmer, Rajasthan, as part of this initiative.

The Positive Indian Ocean Dipole (IOD), also known as the Indian Nino, could potentially resurface for the second consecutive year during the latter part of 2024.

What is the Indian Ocean Dipole (IOD)?

• The Indian Ocean Dipole (IOD) is defined by the difference in the sea surface temperature between the two equatorial areas of the Indian Ocean – a western pole near the Arabian Sea (in western Indian Ocean) and an eastern pole closer to the Bay of Bengal (in eastern Indian Ocean).
• The IOD affects the climate of Southeast Asia, Australia and other countries that surround the Indian Ocean Basin.
  • The Indian Monsoon is invariably influenced by the IOD.
• IOD is simply the periodic oscillation of sea surface temperatures, from ‘positive’ to ‘neutral’ and then ‘negative’ phases.
• If the sea surface temperature of the western end rises above normal (0.4°C) and becomes warmer than the eastern end, it leads to a positive IOD.
  • This condition is favourable for the Indian Monsoon as it causes a kind of barrier in the eastern Indian Ocean and all the southwesterly winds blow towards the Indian sub-continent.
• Accordingly, the waters in the eastern Indian Ocean cool down, which tends to cause droughts in adjacent land areas of Indonesia and Australia.
• Conversely, during a negative IOD period, the waters of the tropical eastern Indian Ocean are warmer than water in the tropical western Indian Ocean.
  • This results in increased rainfall over parts of southern Australia.

Effects on India:

• A positive IOD can boost India's southwest monsoon performance depending on its development timing.
  • Example: In 2019, a strong IOD event improved a 30% rainfall deficit during the late monsoon season.
• Benefits for agriculture through recharging water sources and reservoirs.
• The development of IOD likely benefits India's agricultural sector, particularly in areas with precarious water storage levels.

Difference between El Nino and IOD:

• The Indian Ocean Dipole (IOD) and the El Nino are independent climatic phenomena but often co-occur.
  • Both IOD and El Nino result in changes in global wind patterns. To know about the change of wind patterns, click here.
• However, the cycle of IOD is shorter, while El Nino condition could last for even two years.
• IOD commences in the month of May and ends with the withdrawal of the Southwest Monsoon in the Indian sub-continent.

Recently, scientists have created plant-based plastic that doesn't create cancer-causing microplastics because 97% of it breaks down in the environment.

What is Microplastics?

• Microplastics are small plastic particles measuring less than 5 millimeters in diameter.
• These particles, which are distinguished from larger "macroplastics" like bottles and bags, stem from both commercial product development and the breakdown of larger plastics.
• Microplastics are commonly found in a variety of products, including cosmetics, synthetic clothing, plastic bags, and bottles.
• Unfortunately, many of these products can easily enter the environment as waste.
• Composed of carbon and hydrogen atoms linked in polymer chains, microplastics often contain additional chemicals such as phthalates, polybrominated diphenyl ethers (PBDEs), and tetrabromobisphenol A (TBBPA).
• There are two categories of microplastics: primary and secondary.
  • Primary microplastics are intentionally designed for commercial use, including in cosmetics and microfibers shed from textiles like clothing and fishing nets.
  • Secondary microplastics, on the other hand, result from larger plastic items breaking down due to environmental factors such as sunlight and ocean waves.
• Understanding the sources and types of microplastics is crucial for addressing their impact on the environment, wildlife, and human health, ultimately promoting more sustainable production and waste management practices.

Environmental Impacts of Microplastics:

• Microplastics pose significant environmental concerns due to their resistance to breaking down into harmless compounds, much like larger plastic items.
  • Consequently, both primary and secondary microplastics accumulate and endure once introduced into the environment.
• In marine ecosystems, microplastics have the potential to amalgamate with harmful chemicals before being consumed by marine organisms.
  • Despite efforts, conventional water treatment facilities struggle to completely eliminate microplastics from water sources.
• Additionally, microplastics contribute to air pollution as they are present in dust and airborne fibrous particles, further highlighting their pervasive impact on various environmental systems.

The Blue Leaders High-Level Event on Biodiversity Beyond National Jurisdiction was held in Belgium on March 7, 2024, to urge nations to ratify a new treaty to protect the high seas from pollution, climate change and overfishing.

What is the BBNJ Treaty?

• The BBNJ Treaty, also referred to as the Treaty of the High Seas, is an international agreement aimed at conserving and sustainably managing marine biological diversity in areas beyond national jurisdiction, operating within the framework of the UNCLOS.
  • These areas encompass the high seas beyond exclusive economic zones or national waters.
  • It represents nearly half of the Earth's surface and is characterized by minimal regulation and understanding of their biodiversity, with only 1% currently under protection.
• Launched at the One Ocean Summit in February 2022, the High Ambition Coalition on Biodiversity Beyond National Jurisdiction seeks to unite various delegations involved in BBNJ negotiations toward a comprehensive and ambitious outcome.
• The negotiations focus on key elements agreed upon in 2015, including the conservation and sustainable use of marine genetic resources, area-based management tools such as marine protected areas, environmental impact assessments, and initiatives for capacity-building and technology transfer in marine science and management.
• India is yet to sign the treaty. However, it called on efforts for entry into force and implementation of the treaty at the G20 New Delhi Leaders’ Declaration held in September 2023.

The Importance of a Legally Binding Instrument for BBNJ:

• Biodiversity in areas beyond national jurisdiction is crucial for ocean health, coastal communities' welfare, and global sustainability, constituting 95% of the ocean and offering essential ecological, economic, social, cultural, scientific, and food-security benefits.
• Despite their significance, these areas face escalating threats such as pollution, overexploitation, and the impacts of climate change, compounded by the anticipated rise in demand for marine resources in the future.
• Even the deep seafloors, considered one of the most inhospitable habitats, are experiencing the onset of extinction processes, with alarming statistics showing that 62% of assessed mollusc species are threatened, including critically endangered, endangered, and vulnerable species, while the International Seabed Authority permits deep sea mining contracts.
• It is imperative to establish a legally binding framework for managing and regulating biodiversity in areas beyond national jurisdiction, as over 60% of this resource in the global seas remains unmanaged and unprotected, necessitating comprehensive conservation measures.
