Biodiversity and its conservation with special reference to the state of Rajasthan

Biodiversity-2/”>Biodiversity-Defination, types, importance, hotspots, threats and conservation

The term biodiversity was coined as a contraction of biological diversity by E.O. Wilson in 1985. Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. In other words, biodiversity is the occurrence of different types of Ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, environments along with their interactions and processes.

Types of biodiversity

There are three interrelated hierarchical Levels of Biodiversity namely, Genetic diversity, Species diversity and community or ecosystem diversity.

Genetic diversity

It describes the variation in the number and types of genes as well as Chromosomes present in different species. The magnitude of variation in genes of a species increases with increase in size and environmental parameters of the habitat.  The genetic variation arises by gene and chromosome mutation in individuals and in sexually reproducing organisms and it is spread in the Population by recombination of genetic materials during cell division after sexual Reproduction.

Species diversity

It describes the variety in the number and richness of the spices with in a region. The Species richness may be defined as the number of species per unit area. The richness of a species tells about the extent of biodiversity of a site and provides a means for comparing different sites.  The species richness depends largely on climatic conditions. The number of individuals of different species with in a region represents Species evenness or species equitability. The product species richness and species evenness give species diversity of a region. When a species is confined entirely to a particular area, it is termed as endemic species.

Ecosystem diversity

It describes the assemblage and Interaction of spices living together and the physical Environment a given area. It relates varieties of habitats, biotic communities ecological processes in Biosphere. It also tells about the diversity within the ecosystem. It is referred as Land escape diversity because it includes placement and size of various ecosystems.  For example, the landscapes like grass lands, deserts, Mountains etc. show ecosystem diversity. The ecosystem diversity is due to diversity of niches, trophic levels and ecological processes like nutrient cycling, food webs, energy flow, role of dominant species and various related biotic interactions. Such type of diversity can generate more productive and stable ecosystems or communities capable of tolerating various types of stresses e.g. drought, flood etc.

Importance of biodiversity

The biodiversity has the following importance’s:

 Productive values

Biodiversity produces a number of products harvested from nature and sold in commercial markets. Indirectly it provides economic benefits to people which include water quality Soil protection, equalisation of Climate, environmental monitoring, scientific research, recreation etc.

Consumptive value

The consumptive value can be assigned to goods such as fuel woods, leaves, forest products etc. which may be consumed locally and do not figure in national and international market.

Social value

The loss of biodiversity directly influences the social life of the country possibly through influencing ecosystem functions (energy flow and biogeochemical cycle). This be easily understood by observing detrimental effects of Global Warming and Acid Rain which cause an unfavorable alteration in logical processes.

Aesthetic value

Aesthetic values such as refreshing fragrance of the flowers, taste of berries, softness of mossed, melodious songs of birds, etc. compel the human beings to preserve them. The earth’s natural beauty with its colour and hues, thick forest, and graceful beasts has inspired the human beings from their date of birth to take necessary steps for its maintenance. Similarly botanical and zoological gardens are the means of Biodiversity conservation and are of aesthetic values.

Ecological value

Biodiversity holds great ecological value because it is indispensable to maintain the ecological balance. Any disturbance in the delicately fabricated ecological balance maintained by different organisms, will lead to severe problems, which may threaten the survival of human beings.

Biodiversity hotspots

A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction.

Indian Biodiversity Hotspot area

Western Ghats (Sahyadri Hills)

The Western Ghats, also known as the Sahyadri Hills , is a mountain chain running from the north to the South and is isolated by the Arabian Sea to the West, the arid Deccan Plateau to the East, and the Vindhya-Satpura ranges to the North. They have different vegetation types: scrub jungles and grasslands at low altitudes, dry and moist deciduous forests, montane grasslands and shoals, and the precious tropical evergreen and semi evergreen forests. Complex topography, high rainfall and relative inaccessibility have helped the region retain its biodiversity. Of the 15,000 flowering plant species in India, there are an estimated 4,780 species in the Western Ghats region. There is also a great diversity of traditional crop Plants and an equal diversity of animal life. A large number of amphibians, freshwater fishes and invertebrate groups are endemic to Western Ghats.

Indo-Burma (Eastern Himalayas )

The hotspot contains the Lower Mekong catchment. It begins in eastern Bangladesh and then extends across north-eastern India, south of the Bramaputra River, to encompass nearly all of Myanmar, part of southern and western Yunnan Province in China, all of the Lao People’s Democratic Republic, Cambodia and Vietnam, the vast majority of Thailand and a small part of Peninsular Malaysia. In addition, the hotspot covers the coastal lowlands of southern China (in southern Guangxi and Guangdong), as well as several offshore islands, such as Hainan Island (of China) in the South China Sea and the Andaman Islands (of India) in the Andaman Sea. The hotspot contains the Lower Mekong catchment.

Threats to biodiversity

Biodiversity is considered as a reservoir of Resources to be used for the manufacture of food, medicine, industrial products, etc. But with an increased demand of rapid population Growth, biodiversity is gradually depleting.

Habitat destruction

The primary cause of loss of biodiversity is habitat loss or destruction which is resulted due to the large industrial and commercial activities associated with agriculture, Irrigation, construction of Dams, mining, fishing etc.

 Habitat fragmentation

With increased population, the habitats are fragmented into pieces by roads, fields, canals, power lines, towns etc. The isolated fragment of habitats restricts the potential of species for dispersal and colonization. In addition, the habitat fragmentation also brings about microclimatic changes in Light, temperature, wind etc.

Pollution

The most dreaded factor inducing loss of biodiversity is environmental pollution which include Air Pollution, Water Pollution, industrial pollution, pollution due to chemical Pastes, pesticides radioactive materials etc.

Over exploitation

The Natural Resources are over exploited to meet growing rural POVERTY, intensive technological growth and Globalization/”>Globalization-3/”>Globalization of economy. All these factors together may be responsible for the extinction of a number of species.

Conservation of Biodiversity

Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic spices, diseases, shifting cultivation, poaching of wild life etc.

Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its form and good Health for the future generation i.e., the human being should prevent the degradation and destruction of the habitats thereby maintaining the biodiversity at its optimum level.

Conservation of biodiversity is protection, upliftment and scientific management of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation. In other words, conservation of bio-diversity is the proper management of the biosphere by human beings in such a way that it gives maximum benefits for the present generation and also develops its potential so as to meet the needs of the future generations.

Major national parks and bird sanctuary are Ranthambore national park, Sariska tiger reserve, and Bharatpur bird sanctuary.

Sanctuary is an area which is of adequate ecological, faunal, floral, geomorphological, natural or zoological significance. The Sanctuary is declared for the purpose of protecting, propagating or developing wildlife or its environment. Certain rights of people living inside the Sanctuary could be permitted.

A sanctuary is a protected area which is reserved for the conservation of only animal and human activities like harvesting of timber, collecting minor forest products and private ownership rights are allowed as long as they do not interfere with well-being of animals.

National park is an area which is strictly reserved for the betterment of the wildlife & biodiversity, and where activities like developmental, Forestry, poaching, hunting and grazing on cultivation are not permitted. In these parks, even private ownership rights are not allowed. Their boundaries are well marked and circumscribed. They are usually small reserves spreading in an area of 100 sq. km. to 500 sq. km. In national parks, the emphasis is on the preservation of a single floral or faunal species.

Biodiversity is the variety of life on Earth. It includes all living things, from plants and animals to bacteria and Fungi. Biodiversity is important for many reasons. It provides us with food, medicine, and other resources. It also helps to regulate the climate and protect us from natural disasters.

Rajasthan is a state in northwestern India. It is the largest state in India by area, and the seventh most populous. Rajasthan is home to a wide variety of plants and animals. Some of the most common animals found in Rajasthan include tigers, leopards, elephants, camels, and monkeys. Rajasthan is also home to a number of endangered species, such as the blackbuck and the great Indian bustard.

There are a number of threats to biodiversity in Rajasthan. One of the biggest threats is habitat loss. This is due to deforestation, mining, and other development activities. Another threat is poaching. Poachers kill animals for their fur, meat, and other body parts. Climate Change is also a threat to biodiversity. Climate change is causing changes in temperature and rainfall patterns, which are disrupting ecosystems and making it difficult for some species to survive.

There are a number of things that can be done to conserve biodiversity in Rajasthan. One important step is to protect habitats. This can be done by creating Protected Areas, such as national parks and wildlife sanctuaries. Another important step is to reduce poaching. This can be done by increasing law enforcement and by educating people about the importance of wildlife conservation. Climate change is a more difficult problem to solve, but there are a number of things that can be done to mitigate its effects, such as reducing greenhouse gas emissions and planting trees.

The government of Rajasthan has taken a number of steps to conserve biodiversity. The state has a number of protected areas, including national parks, wildlife sanctuaries, and Biosphere reserves. The government also has a number of programs to reduce poaching and to educate people about the importance of wildlife conservation.

There are also a number of non-governmental organizations (NGOs) working to conserve biodiversity in Rajasthan. These NGOs work on a variety of projects, such as habitat protection, anti-poaching, and Education.

Community participation is essential for the success of any biodiversity conservation effort. Local communities can provide valuable information about the plants and animals in their area, and they can also help to enforce conservation laws. There are a number of ways to involve communities in biodiversity conservation, such as through community-based conservation projects and through education and awareness programs.

Biodiversity conservation is a complex issue, but it is one that is essential for the future of our planet. By working together, we can protect the rich biodiversity of Rajasthan for future generations.

Here are some additional details about the threats to biodiversity in Rajasthan:

• Habitat loss: Rajasthan is home to a variety of ecosystems, including forests, grasslands, deserts, and wetlands. These ecosystems are being destroyed by deforestation, mining, and other development activities. This is causing the loss of habitat for many species of plants and animals.
• Poaching: Poachers kill animals for their fur, meat, and other body parts. This is a major threat to many endangered species in Rajasthan, such as the blackbuck and the great Indian bustard.
• Climate change: Climate change is causing changes in temperature and rainfall patterns. This is disrupting ecosystems and making it difficult for some species to survive. For example, the Thar Desert is becoming drier, which is making it difficult for some plants and animals to find food and water.

Here are some additional details about the conservation efforts in Rajasthan:

• Protected areas: The government of Rajasthan has a number of protected areas, including national parks, wildlife sanctuaries, and biosphere reserves. These protected areas are home to a variety of plants and animals, and they are managed to ensure the survival of these species.
