Recently, our scientists have discovered a new and distinct species of banana plant which attains a height of about 11 metres and has orange-coloured fruit pulp. In which part of India has it been discovered?
Scientists from the Botanical Survey of India (BSI) have discovered a new species of banana, Musa indandamanensis, in the remote tropical rainforests of Little Andaman Island. This remarkable species stands out for its exceptional height, reaching up to 11 meters, nearly three times taller than common banana plants. Located 16 km inside the Krishna Nalah forest, this species is globally distinct due to its unique green flowers, an unusually large fruit bunch axis (lux) thrice the size of regular banana species, and cylindrical-shaped flowers instead of the typical conical form. Additionally, the fruit pulp is orange, differing from the usual white or yellow found in common bananas. This discovery adds significant value to botanical research and biodiversity conservation, highlighting the unique flora of the Andaman Islands.
Consider the following international agreements:
1. The International Treaty on Plant Genetic Resources for Food and Agriculture
2. The United Nations Convention to Combat Desertification
3. The World Heritage Convention
Which of the above has/have a bearing on the biodiversity?
The International Treaty on Plant Genetic Resources for Food and Agriculture focuses on ensuring the conservation and sustainable use of plant genetic resources for food and agriculture. This directly impacts biodiversity as it aims to protect the variety of plant species crucial for food security and ecosystem health. The United Nations Convention to Combat Desertification addresses land degradation in arid, semi-arid, and dry sub-humid areas. Desertification can significantly reduce biodiversity by destroying habitats and reducing plant and animal life. By working to combat desertification, this convention indirectly protects biodiversity. The World Heritage Convention focuses on preserving cultural and natural heritage sites. Conservation natural heritage sites may contribute to biodiversity conservation.
Thus 'D' is the correct answer.
If a particular plant species is placed under Schedule VI of The Wildlife Protection Act, 1972, what is the implication?
* The Wildlife Protection Act, 1972, provides for the protection of wild animals, birds, and plants. It classifies species into six schedules, each offering different levels of protection. * Schedule VI of the Act pertains to certain plants that are prohibited from cultivation and planting without a license. Therefore, If a plant species is listed under Schedule VI, it means a license is required for its cultivation. * The Wild Life (Protection) Amendment Act, 2022 amended the Wild Life (Protection) Act, 1972. The amendment reduced the number of schedules from six to four, simplifying wildlife classification and protection levels. Additionally, the Act also aligned the provisions with CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) by introducing a separate schedule (Sch. IV) for species covered under CITES.
Consider the following statements :
1. In India, the Biodiversity Management committees are key to the realization of the objectives of Nagoya Protocol.
2. The Biodiversity Management committees have important functions in determining access and benefit sharing, including the power to levy collection fees on the access of biological resources within its jurisdiction.
Which of the statements given above is/are correct?
* The Nagoya Protocol is an international agreement that addresses the fair and equitable sharing of benefits arising from the utilisation of genetic resources. It is a supplementary agreement to the Convention on Biological Diversity (CBD) and specifically focuses on access to genetic resources and the fair and equitable sharing of benefits derived from their utilisation. * Statement 1 is correct: In India, the Biodiversity Management Committees (BMCs) are indeed key to the realisation of the objectives of the Nagoya Protocol. The Nagoya Protocol aims at sharing the benefits arising from the utilisation of genetic resources in a fair and equitable way. BMCs play a crucial role in this by ensuring that local communities have a say in the access to and use of these resources. * Statement 2 is correct: The Biodiversity Management Committees also have important functions in determining access and benefit sharing. They have the power to levy collection fees on the access of biological resources within their jurisdiction. This is part of their role in managing and conserving biodiversity, and ensuring that the benefits derived from the use of these resources are shared equitably. Therefore, both statements are correct.
Why is a plant called Prosopis juliflora often mentioned in the news?
* Prosopis juliflora, commonly known as mesquite or thorn mimosa, frequently appears in discussions about invasive species due to its significant impact on ecosystems and biodiversity. * Originally native to Central and South America, Prosopis juliflora was introduced to various parts of Africa, Asia, and Australia for purposes like afforestation, erosion control, and fuelwood supply. * However, due to its rapid growth rate, tolerance for harsh conditions, and prolific seed production, it can become invasive. * It can outcompete native plants, disrupt ecological balances, and form dense thickets that hinder other vegetation growth. * In states like Tamil Nadu, Prosopis juliflora has been labelled an invasive species causing ecological damage. Efforts are underway to remove it from certain areas to restore native ecosystems.
