"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

2. The Concept of Biodiversity
• The term biodiversity is a relatively new term.
• It is a contraction of ‘biological diversity’.
• Simply stated, biodiversity is the variety of life on earth and its myriad of processes.
• It includes all life forms – from the unicellular fungi, protozoa and bacteria to
complex multicellular organisms such as plants, birds, fishes and mammals.
• According to the World Resources Institute – “Biodiversity is the variety of the
world’s organisms, including their genetic diversity and the assemblage they form.
• It is the blanket term for natural biological wealth that under girds human life and
well-being.
• The breadth of the concept reflects the inter-relatedness of genes, species and
ecosystems.
• Because genes are the components of species, and species are the components of
ecosystems.
• Therefore, altering the make-up of any level of this hierarchy can change the others
– species are central to the concept of biodiversity’.
3. Since biodiversity covers a wide range of concepts and can be
examined at different levels; therefore, it has now become
customary to study the concept of biodiversity at three hierarchical
levels.
• Genetic diversity
• Species diversity
• Ecosystems diversity
4. Genetic diversity
• Within any given species, there can be several varieties, strains or races which
slightly differ from each other in one or more characteristics such as size,
shape, resistance against diseases, pests, insects, etc., and resilience to
survive under adverse environmental conditions.
• Such diversity in the genetic make-up of a species is termed as the ‘genetic
diversity’. In other words ‘genetic diversity’, is the variety of building blocks
found within individuals of a species.
• The species having large number of varieties, strains or races are considered as
rich and more diverse in its genetic organization.
• The differences between individual organisms arise from variation in the genetic
material possessed by all organisms and passed on to successive generations
(heritable variation), and from environmental influence on the growth and
development of each individual organism.
• Heritable variation serves as the raw material for both, evolution by natural
selection and by artificial selection, and is ultimately the basis for all biodiversity.
5. • Opportunities for evolutionary change, the
survival of species and the formation of new
species are in part a function of the amount of
genetic diversity in populations.
• The various applications of biotechnology,
such as crop or animal breed improvement,
depend on the identification of genetic material
that give rise to desirable traits and the
incorporation of this genetic material in
appropriate organisms.
6. Species diversity
• In practice, most attention is generally given to ‘species diversity’.
• It refers to the number of different kinds of organisms found at a
particular place, and how it varies from place to place and even
seasonally at the same place. In terms of species diversity, it must be
noted that merely counting the number of species is not enough to
describe biological diversity.
• Diversity has to do with the relative chance of seeing species as much
as it has to do with the actual number present.
• A community in which each species has the same number of
individuals as all others would be the most diverse; whereas, a
community with one species making up most of the individuals would
be least diverse.
• Further, species that are very different from each other contribute more
to overall diversity than species which are similar to each other.
7. Ecosystems diversity
• Ecosystem diversity is generally assessed in terms of the global or
continental distribution of broadly-defined ecosystem types, or in
terms of the species diversity within ecosystems.
• It is the distinctive assemblage of species that live together in the
same area and interact with their physical environment in unique
ways.
• A system having the component species present in nearly equal
abundance is considered as more diverse than one having extremes
of high and low abundance.
8. Landscape diversity
Sometimes, the phrase ‘landscape diversity’ is used on a
broad regional scale. It refers to size and distribution of
several ecosystems and their interaction across a given land
surface.
9. Bio-Geographic Zones of India
• India is recognized to be uniquely rich in biodiversity.
• Here, almost all the bio geographic zones of the world are
represented.
• According to a recent classification done by the Wild-life
Institute of India, the country’s biological wealth can be
seen as representing about ten broad bio-geographical
zones.
• Each of these ten bio-geographic zones has characteristic
biota, and broadly represents similar climatic conditions
and constitutes the habitat for diverse species of fauna
and flora.
10.
11. Trans-Himalayan zone
• The Trans-Himalayan zone, spreads over an area of about
1,86,000 sq.km.
• With its sparse mountain vegetation type it has the richest
wild sheep and goat community in the world.
• The snow leopard is found here, as is the migratory black-
necked crane.
• Plants of high medicinal values such as the species of
Aconitum, Nardostachys, Neopicrorhiza, and Sedum occur in
this zone of stressed environment conditions
• The vegetation types are xerophilous, steppe formation and
alpine formation with woody shrubs in the river valleys.
12. Himalayan zone
• The Himalayan zone extends from north-west region of Kashmir
to the east up to NEFA (North East Frontier Area).
• It encompasses an area of about 3,47,000 sq.km and comprises
of four biotic provinces--north-west, west, central and east
Himalayas.
• Altitudinally, there are three zones of vegetation in the Himalayan
zone corresponding to three climatic belts.
• First, the sub-montane or lower region (tropical and sub-tropical),
that extends from plain foot of the hill upto 5,000 to 6,000 ft.
altitude, has vegetation dominated by trees of Acacia catechu,
Cedrala toona, Eugenia jambolana, Albizzia procera, etc.
13. • Second, the temperate or montane zone (ranges between 5,500
to 12,000 ft. altitude) has vegetation dominated by Pinus excelsa,
Cedrus deodara, Cedrela, Eugenia, etc. in the lower region, and
confers such as Abies pindrow, Picea morinda, Juniperus, Taxus
baccata, etc. in the upper regions.
• Third, the alpine zone (above 12,000 ft.) is the limit of tree growth
(known as ‘timber or tree line’), where the shrubby growth of
Betula utilis, Juniperus and Rhododendron is found in grassy
areas. At about 15,000 ft. and above snow-line, plant growth is
almost nil.
14. Desert zone
• The desert zone comprises of three biotic provinces, viz. Kutch, Thar
and Ladakh.
• The north-west Desert region (Kutch and Thar) spreads over an area
of about 2,25,000 sq.km. and consists of parts of Gujarat, Rajasthan,
Haryana and Delhi.
• The climate of this region is characterized by very hot and dry
summer, and cold winter.
• Rainfall here is less than 700 mm. The north-west desert region has
extensive grasslands.
15. • The plants are mostly Xerophytic, such as Acacia nelotica,
Prosopis spicifera, etc.; and the ground vegetation is dominated by
the species Calotropis, Eleusine, Panicum antidotale, etc.
• The Great Indian Bustard, a highly endangered species, is found in
this north-west desert region.
• The Ladakh region, on the other hand, has sparse vegetation – it is
a cold desert region.
16. Semi-Arid zone
• Adjoining the north-west desert are the Semi-Arid areas comprising
of Madhya Pradesh, Chattisgarh, parts of Orissa and Gujarat.
• It spreads over an area of about 5 lac sq.km.
• Depending upon the amount of rainfall, the forests in this region
have developed into thorny, mixed deciduous and sat type.
• The forest vegetation is mostly constituted by Tectona grandis,
Diospyros melanoxylon and Butea monosperma.
• The thorny vegetation is dominated by Acacia leucophloea, Accacia
catechu, etc.
17. Western Ghats zone
• The Western Ghats zone comprises the Malabar coast and Western
Ghat mountains of India extending from Gujarat in the north to the
Cape Camorin in the south.
• This zone encompasses an area of about 1.6 lac sq.km.
• Rainfall in this region is heavy.
• The vegetation is of four types – tropical moist evergreen forests, sub-
tropical or temperate evergreen forests, mixed deciduous forests and
the mangrove forests.
18. Deccan peninsular zone
• The Deccan Penninsula zone comprises of five biotic
provinces, viz. Deccan Plateau (South), Central Plateau,
Eastern Plateau, Chhota Nagpur Plateau and Central
Highlands.
• The zone spreads over an area of about 14 lac sq. km. It is a
semi-arid region lying in the rain-shadow of the Western
Ghats.
• Rainfall is about 100 mm.
• The zone has a centrally hilly plateau with forests of
Boswellia serrata, Hardwickia Pinnata and Tectona grandis.
19. Gangetic plain
• In the North, is the Gangetic Plain extending up to
Himalayan foothills.
• This region comprising of Uttar Pradesh, Bihar and West
Bengal is the most fertile region and encompasses an area
of about 3.5 lac sq.km.
• The major climatic factors, the temperature and rainfall
together are responsible for the distinctive type of vegetation
in this zone.
• The rainfall varies from less than 700 mm in Western Uttar
Pradesh to more than 1,500 mm in West Bengal.
• Vegetation is chiefly of tropical moist and dry deciduous
forest type.
20. The north-east India
• The North-East India is one of the richest flora regions in the
country covering an area of about 1.6 lac sq.km.
• The region receives the heaviest rainfall, with Mausinram as much
as more than 10,000 mm.
• The temperature and wetness are also very high, resulting in
dense tropical evergreen forests.
• The important trees are Mesua ferrea, Michelia champaca,
Dipterocarpus macrocarpus etc., and many Bamboo species.
• Many grass species and insectivorous plants like are also
present.
• Beside this, the region has several wild relatives of cultivated
plants such as banana, mango, citrus and pepper.
21. Islands
The Islands of Lakshadweep in the Arabian Sea, and
Andaman and Nicobar Islands in the Bay of Bengal have a
wide range of coastal vegetation like mangroves, beech
forests and in the interior some of the best preserved
evergreen forests of tall trees. Rhizophora, Calophyllum and
Dipterocarpus are some of the important species of Islands’
vegetation.
Coast
India has a coastline of about 7,516.5 km. Mangroves
vegetation is the characteristic of estuarine tracks along the
coast, for instance, at Pichavaram near Chennai and
Ratnagiri in Maharashtra.
22. VALUES OF BIODIVERSITY
Values of Biodiversity
Environmental economics (or ecological economics) provides
methods of assigning economic values to species, communities
and ecosystem. These values include the harvest (or market
place) value of resources, the value provided by un-harvested
resources in their natural habitat, and the future value of
resources. For example, the Asian wild guar could be valued for
the meat could be harvested from its current populations, its
value for eco-tourism, or its future potential in cattle breeding.
23. The values can be divided as:
Direct values: Direct values, also known as use values and commodity
values, are assigned to the products harvested by people. Direct values
can be readily estimated by observing the activities of representative
groups of people, by monitoring collection points for normal products and
by examining the export/ import statistics. These values can be further
sub-divided as:
a) Consumptive use value: It can be assigned to goods such as fuel
wood and goods that are consumed locally and do not figure in national
and international market
b) Productive use value: It is assigned to products that are derived from
the wild and sold in commercial markets, both national as well as
international markets.
24. Indirect values:
Indirect values are assigned to benefits provided by biodiversity that do not
involve harvesting or destroying the natural resource. Such benefits
include ecological benefits such as soil formation, nutrient cycling, waste
disposal, air and water purification, education, recreation, future options for
human beings, etc. Indirect value can be further sub-divided as:
a) Non-consumptive use value
It is assigned to benefits such as soil formation/ protection, climate
regulation, waste disposal, water and air purification, eco-tourism, medical
research, etc.
b) Aesthetic, social and cultural value
The diversity of life on Earth brings us many aesthetic and cultural benefits.
It adds to the quality of life, providing some of the most beautiful and
appealing aspects of our existence.
25. • Biodiversity is an important quality of landscape beauty. Many species of
birds, large land mammals, sea animals and flowering plants are
appreciated for their beauty.
• Millions of people enjoy hiking, camping, picnics, fishing, wildlife
watching, and other recreational activities based on nature.
• These activities provide invigorating physical exercise and allow us to
practice pioneer living skills.
• Contact with nature can also be psychologically and emotionally
restorative. In many cultures, nature carries spiritual connotations, and a
particular plant or animal species or landscape may be inextricably linked
to a sense of identity and meaning.
• Today we continue to imbue certain animals and plants with cultural
significance; for instance, in India tiger and peacock, which are
endangered, are especially valued because they have been adopted as
national animal and bird respectively.
26. c) Option value
The option value of a species is its potential to provide our economic benefit
to human society in the near future. For instance, there are several plant
species which are edible and superior than those which are currently in use;
e.g. Katemfe, a plant found in W. Africa, produces proteins that are 1,600
times sweeter than sucrose.
d) Existence value
It is assigned to protect wildlife. Since, for many people, the value of wildlife
goes beyond the opportunity to photograph or even see a particular
species. They argue that ‘existence value’, based on simply knowing that a
species exist, is a sufficient reason to protect and preserve it. This right to
exists was also stated in the U.N. General Assembly World Charter for
Nature, 1982.
27. e) Ethical value
Moral justification for conservation of biodiversity is based on the
belief that species have a moral right to exist, independent of our need
for them. Consequently, the argument follows that in our role as the
most intelligent species on Earth we have a responsibility to try as
much as possible for the continuance of all forms of life.
Ethical values are deep rooted within human culture, a religion and
society, but, those who look on cost benefit analysis, they overlook
these ethical values. International boycotts of furs, teak and ivory are
the good examples of moral justification.
28. Significance/ Importance/ Uses of Biodiversity
Various uses of biodiversity regarding direct and indirect values are as
follows:
Timber:
• Wood is one of few commodities used and traded worldwide that is
mainly harvested from wild sources. It is also one of the economically
most important commodities in national and international trade.
• Wood export constitutes a significant part of the export earnings of
many tropical developing countries.
• Malaysia, Papua New Guinea and Indonesia are among the major
exporters of hardwoods, including prized timbers such as teak and
mahogany, produced mainly from natural forests.
29. Fishery
• Fish and other fishery products make up another class of
commodities of great economic importance in international trade
that are harvested mainly from wild sources.
• These resources are also of crucial importance to global food
security.
• Annual landings of aquatic resources have increased nearly five-
times in the past four decades; and more than 80% was harvested
from marine capture fisheries, the remainder was from inland
fisheries and from aquaculture, both inland and marine.
• Though there are over 22,000 species of fish, but just ten individual
marine fish species make up one-third of marine capture landings.
• The most important are the herrings, sardines and anchovies
group.
30. Food
• Food plants exemplify the most fundamental values of biodiversity.
• Presently, around 200 species have been domesticated as food
plants.
• Out of these about 15 to 20 are of major international economic
importance.
31. Medicinal value
• Living organisms provide us with many useful drugs and medicines.
• Digitalis, an important drug in the treatment of certain heart ailments,
comes from a small flowering plant – purple foxglove; Penicillin is a
derivative of fungus; and so on.
• The UNDP estimates the value of pharmaceutical products derived from
Third World plants, animals and microbes to be more than $30 billion per
year.
• There are numerous organisms that may produce useful medical
compounds that are as yet unknown and untested.
• For instance coral reefs offer a particularly promising use in pharmaceutical
drugs, because many coral reef species produce toxins to defend
themselves.
• Many plant species native to India such as Neem, Tulsi, etc. too have
potential medicinal applications.
32.
33. Genetic value
Biological diversity is a valuable genetic resource. Most of the hybrid
varieties of crops under cultivation have been developed by
incorporating useful genes from different species of plants to produce
better quality of the product with longer self-life or having better
resistance to pests. Though such breeding techniques are unlimited in
scope; but, for getting better strains in future, it is essential to build-up
a gene-pool because the quality, yield, and resistance to pests,
disease and adverse climatic conditions mostly depend on genetic
factors and combination of genes which may be different in different
strains/ varieties of species. There are hundreds of examples which
illustrate how genetic modification helped in improved quality of the
product. A few of them are mentioned as under:
34. • The genes from a wild variety of melon grown in U.P. helped in
imparting resistance to powdery mildew in musk-melons grown
in California (USA).
• The genes from the Kans grass (Saccharum spontaneium)
grown in Indonesia helped in imparting resistance to red rot
disease of sugarcane.
• A wild variety of rice from U.P. saved millions of hectares of
paddy crop from Grossy-Stunt virus.
35. Tourism
Tourism industry is mainly based on observation of wildlife within
protected areas and is a major source of income for many developing
countries. Tourism is the major source of foreign income for Kenya.
Eco-tourism is now getting more attention and it includes interest in
the all species of plants and animals, and forests.
Poor and indigenous people
Poor and indigenous people of under-developed countries are
dependent on diversity in forests and wildlife for food, shelter, tools,
and materials for clothing and medicines. Further reduction in the
biodiversity can further increase the poverty of these poor people.
36. Pollution control
Plants and certain micro-organisms in particular can remove toxic
substances from the air, water and soil. Since the different
species have different characteristics and capabilities, therefore,
a diversity of species can provide wide range of pollution control.
For example, toxins like carbon-di-oxide and sulphur-di-oxide are
removed by vegetation; carbon-monoxide is controlled by soil
fungi and bacteria.
