A taxon is considered Vulnerable if the best available evidence indicates that it meets any of the criteria for Vulnerability, i.e. criteria reduction in population (> 50% over the last 10 years), population size estimated to be fewer than 10,000 mature individuals, probability of extinction in wild is at least 10% within 100 years, and it is thus considered to be facing a high risk of extinction in the wild. In this article, we will discuss Vulnerable (VU) which will be helpful for UPSC exam preparation.

What are Vulnerable Species?

• A vulnerable species is one that, according to the International Union for Conservation of Nature, is on the verge of extinction unless the circumstances threatening its survival and reproduction improve.
• The primary cause of vulnerability is habitat loss or destruction of the species' home.
• Vulnerable habitat or species are being monitored and may become increasingly endangered. Some "vulnerable" species, such as the military macaw, may be common in captivity.
• There are currently 5196 animals and 6789 plants classified as vulnerable, up from 2815 and 3222, respectively, in 1998.
• Cryoconservation of animal genetic resources, for example, has been implemented in efforts to conserve vulnerable livestock breeds.

Criteria for Vulnerable Species

Population Reduction

• A taxon's population size is reduced by 50% or more over 10 years or three generations, whichever is longer, and scientists understand that the causes of the reduction are reversible and have stopped.
  • Assume there is a bird species with a traditional population of 2000. It falls to 1000 after a logging company destroys its habitat over a ten-year period.
  • If lawmakers enact regulations that prevent the logging company from continuing to fell trees in the area, the IUCN will list the bird species as "endangered" because they understand the cause of the decline and it is halted.
• Over ten years or three generations, the population of a taxon is reduced by 30% or more. However, conservationists do not understand the cause of the reduction or whether it is reversible.
  • Assume there is a bird species with a traditional population size of 2000. Over a ten-year period, it falls to 1400. Scientists, on the other hand, have no idea why they're dying out.
  • The IUCN would list it as "endangered" in this case because the decimation is obvious, but it can't figure out why.
• A taxon's population size is reduced by 30% or more over 10 years or three generations, whichever is longer, and the animal is also facing habitat shrinkage or another threat.

Geographic Reduction

• The population is not known to exist in more than ten locations.
• Scientists observe or predict that the habitat in question will continue to shrink or be degraded, as well as a decline in subpopulations or the number of reproducing adults.
• Scientists have observed extreme fluctuations in the number of locations, subpopulations, or reproducing adults.

Dangerously Low Number of Adults

• A taxon's population has 10,000 or fewer adults left, and a 10% decline is expected within 10 years or three generations, whichever comes first.
• If none of the taxon's subpopulations have more than 1,000 adults, or if all of the adults live in one subpopulation.
• Scientists have observed extreme fluctuations in the number of mature adults in a taxon's population.

Overall population size is dangerously low

• Only 1,000 or fewer individuals of a taxon remain.
• A population with a viable but limited habitat area is vulnerable to human activities in a very short period of time and may become critically endangered or extinct in the near future.

Expected Rapid Decline

• According to research, there is a 10% or higher chance that the taxon will become extinct in the wild within the next 100 years.

Examples of Vulnerable Species

African Elephant, American Paddlefish, Clouded Leopard, Cheetah, Dugong, Far Eastern Curlew, Fossa, Galapagos Tortoise, Gaur, Blue-eyed Cockatoo, Golden Hamster, Whale Shark, Crowned Crane, Hippopotamus, Humboldt Penguin, Indian Rhinoceros, Komodo Dragon, Lesser White-fronted Goose, Lion, Mandrill, Maned Sloth, Mountain Zebra, Polar Bear, Red Panda, Sloth Bear, Takin, and Yak

Preventing the Loss of Diversity

• A thorough understanding of the factors that cause extinction and the vulnerability of different species to them is an essential part of species conservation.
• Conservation is largely about removing or reducing those factors, and doing so for the most vulnerable species and in the places where they are most vulnerable.
• Much of the work of conservationists is to protect habitats large enough to support viable populations of species, first deciding where the priorities should be and sometimes restoring habitats that have already been destroyed.
• Local conservation groups frequently devote time to removing invasive species, which can include physically weeding invasive plants or trapping invasive animals. These activities must be accompanied by efforts to prevent the introduction of new threats.
• Others work to reduce harvesting directly or to reduce incidental catch of nontarget species. Nonetheless, there are a variety of specific tools that can be applied to different situations, as categorised below and illustrated by case studies.
• When working with extremely rare species, scientists may not always know what is threatening them, which can lead to heated debates about how to proceed.

Conclusion

One of the most well-known objective assessment systems for classifying the status of plants, animals, and other organisms threatened with extinction is the IUCN Red List of Threatened Species, also known as the IUCN Red List. If a species' population has declined by at least 50% and the cause of the decline is known, it is considered vulnerable. The leading known cause of population decline is habitat loss. A species is considered vulnerable if its population has declined by at least 30% and the cause of the decline is unknown.

GS Mains Questions and Model Answers

Q1: Discuss the impact of increasing consumption of goods on the Indian economy.

Answer: In India, the increasing consumption of goods plays a vital role in driving economic growth. It boosts aggregate demand, leading to higher production, increased employment, and improved standards of living. However, if consumption outpaces supply, it can lead to inflationary pressures. Additionally, policies aimed at stimulating consumption, such as tax cuts or subsidies, can help maintain balanced growth while avoiding negative effects like inflation. Consumer demand also impacts the manufacturing and service sectors, contributing to a dynamic and expanding economy.

Q2: How does the demand for consumption goods influence government fiscal policies?

Answer: The demand for consumption goods significantly influences government fiscal policies, as a rise in demand can lead to higher tax revenues and stimulate economic growth. In response to increasing demand, the government may introduce policies such as tax cuts to further encourage consumption. Additionally, during times of low demand, the government may use stimulus measures to boost consumption, thereby stimulating production and employment. The consumption patterns of goods also inform decisions on welfare programs, subsidies, and social security measures aimed at boosting consumer spending in the economy.

Q3: Evaluate the role of consumption goods in India's economic development.

Answer: Consumption goods play a critical role in India’s economic development by driving domestic demand and contributing to GDP growth. They directly affect industries such as retail, manufacturing, and services. With rising incomes and a growing middle class, there is increased demand for both durable and non-durable goods, which stimulates production and creates employment opportunities. The government’s focus on improving infrastructure, along with rising consumer confidence, further enhances the growth of consumption goods markets. However, it is important to balance consumption growth with production capacity to avoid inflationary pressures.

Previous Year Questions on  Vulnerable

1. UPSC CSE Prelims 2020 

Question: Which of the following is classified as a durable consumption good?

A) Television
B) Food
C) Toothpaste
D) Milk

Answer: (A)

Explanation: A television is considered a durable consumption good because it has a long life span and is used over time. Non-durable goods, such as food and milk, are consumed quickly and replaced more frequently.

2. UPSC CSE Mains 2018 

Question: Analyze the impact of increasing consumption of goods on inflation and economic growth in India.

Answer: An increase in the consumption of goods leads to higher aggregate demand, which can fuel inflation if the supply does not meet this rising demand. In India, as consumption rises, businesses ramp up production, leading to increased economic growth. However, the government must monitor inflationary pressures, especially in sectors like food and fuel, where demand often exceeds supply during periods of economic boom.
