India’s relation with Central Asia:

Our prime minister, Narendra Modi, visited the five central Asian countries namely Kazakhstan, Kyrgyzstan, Turkmenistan, Tajikistan and Uzbekistan and this visit became all the more crucial because despite having historical and cultural relations with central Asia, the ties between these countries and India have been a low-key affair. Mr. Modi is the first Indian prime minister to visit all these central Asian nations in one go.  After the collapse of Soviet Union, these countries broke out from the union and in that period of turmoil they looked up to India for both economic and strategic cooperation but the hopes never got fulfilled. UPA-2 when was in power, formulated a policy called ‘connect central Asia’ in 2012 but failed to make any significant impact. As the Chinese and Russian influence keeps on growing in the central Asian region, these countries look up to India to play a balancing role to counter their influence.

China is majorly an economic stakeholder with all the large scale investments in the field of connectivity and energy. Russia on the other hand has been a security provider which provides military cooperation to the central Asian region. During Soviet period we had very good relations but it has declined in last 20-25 years. Though  India has been politically close to the region but it is now high time to play a bigger role.  One of the major reasons of India’s failure to develop strong ties with the region is connectivity issues. It does not have a direct access to these nations. In order to connect, India has to take the route through Afghanistan or Pakistan on the western side and through China on the northern side and both the routes have their own issues.

India relation with central asia

So to have a direct access to these central Asian republics, India can use its soft power through multilateral organisations like Shanghai Cooperation Organisation (SCO) and Eurasian Economic Union (EEU). Mr. Modi’s visit happened on a very crucial time when the region undergoing transformation and now Indian can show its keenness towards playing an active role. India’s main focus is now on security and energy cooperation. Trade is also an important aspect as India can be a huge market when the central Asian countries are looking for different outlets and that we can do through Chabahar port in Iran and railway route between Kazakhstan, Turkmenistan and Iran.

On the other hand, India must understand that it does not need to compete with Russia or China but instead should focus on rightly projecting itself. When we look at the trade relations, we are no match to China as its investment is over 30 billion dollars in central Asia and India’s is less than one billion. So as of now India can only focus on improving its relations in different aspects rather than competing because Russia and China are indispensable for the central Asian region.

In conclusion, it is definitely a good time for India to finally utilize the opportunity and make its presence feel in the central Asian region if it dedicatedly takes further the foundation built during this visit.

The Himalayas: An insight into their evolution and importance

10
himalayas

THE HIMALAYAS:

Himalayan mountains are the gigantic snow filled mountain ranges which cover the northern part of the Indian sub-continent. Besides the mighty Everest, many other highest peaks of the world lie in the Himalayan ranges. Without the Himalayas, our country would have been a desert as they prevent the cold continental air masses of central Asia from entering India. We always wonder how these mighty Himalayas are formed. In this article, we will discuss about their evolution and importance.

EVOLUTION OF HIMALAYAS:

Many million years ago the world map was not similar to the one we are familiar now. There are only two large land masses, Angara land in the north and Gondwanaland in the south separated by a huge water body called Tethys Sea. Over time, these lands were split into many plates and started moving in different directions.

The Indian plate which was separated from Gondwanaland started moving north and over a long period of time it came near the Asian plate. By this time, Tethys Sea was a small water body separating Indian plate and Asian plate. When Indian plate started moving further north towards Asian plate,the debris (deposited material) present in the Tethys Sea started rising(Imagine two plates placed in the sand with some distance. When we try to bring the plates together by applying force the sand in between rises above. The same thing happened here).

Over millions of years, the material had risen to greater altitudes and that’s how the present-day The Himalayas were formed. The interesting fact is that the height of Himalayas is still rising that means the Indian plate is still pushing itself towards the north. Since this is a convergence zone of two plates the complete Himalayan region is the earthquake prone zone. You can now easily relate to the recent disastrous earthquake in Nepal.

IMPORTANCE OF HIMALAYAS:

The Himalayas play a very important role in different aspects according to the needs of our country:

GEOGRAPHICAL IMPORTANCE:

Located in the north, Himalayas protect as well as provide us. They obstruct the cold winds coming from the central Asia and thereby protecting the country from becoming a cold desert. The monsoonal winds coming from the south are reflected back by the Himalayas, causing rain in the northern part of the country.

NATURAL VEGETATION:

The unique feature of Himalayas is that they have all types of vegetation across their altitudes which are present all over the world across latitudes. That means ranging from tropical forests in lower heights to alpine vegetation in higher altitudes it covers almost every kind of flora and fauna.

PILGRIMAGE HUB:

Many famous temples like Badrinath, Kedarnath, Amarnath, Manasarovar and hill stations like Shimla, Manali are present in the Himalayas attracting tourists not only from India but also from the other parts of the world. This helps in the revenue generation and enriching our cultural heritage as well.

CONCLUSION:

In addition to these Himalayan mountains provide us with many mineral resources and of higher strategic importance as well.

Disaster Management

disaster management

Though disaster management has been an indispensable part of regular curriculum in schools the world over for quite some time, it is only for the last few months that people all over the world have been talking about it, as the media across the world flashed news about several devastating incidents — both natural and man-engineered — one after another.

The June 2013 Uttarakhand disaster surpassed all in magnitude because 2,000 villages were devastated in varying degrees, 1,500 roads were washed away and 150 bridges were damaged. The heavy rains due to cloudbursts caught the people unawares and brought down innumerable buildings at several places and thousands of hapless pilgrims, tourists as well as local people had to lose their lives in holy land of centuries-old temples.

The seriousness of the situation can be gauged from the fact that after two weeks of the disaster, trucks carrying ration were parked afar off in Rishikesh, Dehradun, Haridwar and Haldwani for want of clearances and the administration’s failure to ensure distribution of food grains, biscuits, drinking water and oil among the starving in the flood-ravaged areas. Actually, floods had cut-off 600 villages from the outside world rendering all access impossible. The disaster witnessed the largest-ever rescue efforts, as 43.7 percent area of the State was affected due to 440 percent more rainfall than normal till June 18, 2013.

In fact, there is no part or country on this planet which is not susceptible to disaster, though vulnerability to disaster varies from place to place. Disaster management has been defined as the organisation or management of resources and responsibilities for dealing with all humanitarian aspects of emergencies, in particular, preparedness, response and recovery in order to lessen the impact of disasters.

Principles of Disaster Management

In 2007, the first attempt was made to define the all-acceptable principles of Disaster Management. The necessity of defining the principles was felt when a meeting was convened by Dr. Wayne Blanchard of the US’s Federal Emergency Management Agency (FEMA)’s Emergency Management Higher Education Project at the direction of Dr. Cortez Lawrence, Superintendent of FEMA’s Emergency Management Institute.

To this meeting, a working group of emergency management practitioners and academics were invited to consider the principles of emergency management. In fact, this meeting was the result of the realization that while numerous books, a large number of papers and articles referred to principles of emergency management, nobody had ever tried to give an agreed-upon definition of what these principles were.

It is at this meeting that the working group agreed on eight principles that would guide the development of a doctrine of disaster management. The eight principles are as follows :

1. Comprehensive: Disaster managers consider and take into account all hazards, all phases, all stakeholders and all impacts relevant to disasters.

2. Progressive: Disaster manag&rs anticipate disasters, hence take preventive and preparatory measures to build disaster- resistant and disaster-resilient communities.

3. Risk-driven: Disaster managers use sound risk management principles (hazard identification, risk analysis, and impact analysis) in assigning priorities and resources.

4. Integrated: Disaster managers ensure unity of effort among all levels of
government and all elements of a community.

5. Collaborative: Disaster managers create and sustain broad and sincere relationships among individuals and organizations to encourage trust, advocate a team atmosphere, build consensus and facilitate communication.

6. Coordinated: Disaster managers synchronize the activities of all the stakeholders to achieve a common purpose.

7. Flexible: Disaster managers use creative and innovative approaches to solving disaster challenges.

8. Professional: Disaster managers value a science and knowledge-based approach, based on education, training, experience, ethical practice, public stewardship and continuous improvement.

World Conference on Disaster Reduction

The Yokohama Strategy and Plan of Action for a Safer World were adopted at the Yokohama Conference on Disaster Reduction in May 1994. Ten years later, a major international event was planned to assess the progress made against the plan of action from Yokohama.

The event was a platform for the presentation and adoption of specific goals, activities and policy measures, based on a review of the progress since Yokohama. This conference was of particular importance, as the commitment to an understanding of disaster management had been moving forward internationally, impacts of disasters continued to rise and remained a major obstacle to development.

This recognition was of special resonance within the Disaster Management Plan (DMP), as it highlighted the connections between relief and development and the need to devise new strategies for addressing this gap. Based on its close partnership with United Nations International Strategy for Disaster Reduction (UNISDR), DMP/UN-HABITAT played a leading role in the conference in Kobe in 2005.

The International Recovery Platform

The International Recovery Platform (IRP) was conceived at the World Conference on Disaster Reduction (WCDR) in Kobe, Hyogo, Japan in January 2005. As a thematic platform of the International Strategy for Disaster Reduction (ISDR) system, IRP was a key pillar for the implementation of the Hyogo Framework for Action (HFA) 2005—2015.

At the WCDR in 2005, a global plan for disaster risk reduction for the decade was adopted by 168 governments, building the Resilience of Nations and Communities to Disasters. Growing understanding and acceptance of the importance of disaster risk reduction depend on the subject’s embodiment in global commitments to sustainable development, most clearly expressed in the Johannesburg Plan of Implementation of the World Summit on Sustainable Development in 1992, especially through its provisions on vulnerability, risk assessment, and disaster management.

United Nations

United Nations also responds to the disasters taking place worldwide and the responsibility for emergency response is delegated to the Resident Coordinator within the affected country. However, it has been the practice to coordinate the international response whenever the affected country’s government has requested. The UN Office for Coordination of Humanitarian Affairs (UN-OCHA) has been deploying a UN Disaster Assessment and Coordination (UNDAC) team.

World Bank

The World Bank has played a significant role, so far as disaster management is concerned and carried out a large number of operations related to this area. Its operations have included both post-disaster reconstruction projects and projects with components aimed at preventing and mitigating disaster impacts.

It has done a significant job in Argentina, Colombia, Bangladesh, Haiti, India, Mexico, Turkey and Vietnam among other countries. Its common areas for focus for prevention and mitigation projects include forest fire prevention measures like early warning measures and education campaigns to dissuade farmers from engaging in slash-and-burn agriculture that ignites forest fires; early warning system for hurricanes; flood prevention mechanisms, ranging from shore protection and terracing in rural areas to adaptation of production and earthquake-resistant construction.

A Global Risk Analysis of Natural Disaster Hotspots has also been established by the World Bank in collaboration with Columbia University under the umbrella of ProVention Consortium.

In June 2006, the Global Facility for Disaster Reduction and Recovery (GFDRR) was established by the World Bank in collaboration with other aid donors to reduce disaster losses by mainstreaming disaster risk reduction in development, in support of the Hyogo Framework of Action.

It is now accepted by all that disasters of all types—natural disasters like floods, hurricanes, earthquakes and volcano eruptions; environmental disasters which include technological industrial accidents, usually involving hazardous material; complex disasters involving a breakdown of authority, looting and attacks on strategic-locations during conflict situations and war; and pandemic disasters involving a sudden onset of a contagious or infectious disease that affects not only health, but also disrupts services and businesses—result in colossal economic and social loss.

Local regional, national and international organizations are showing great concern about disasters and try to act whenever and wherever a disaster takes place. For example, since 2001, the European Union (EU) has adopted Community Mechanism for Civil Protection, which has started to play a significant role on the global scene.

It gives countries access to a platform, to a one-stop-shop of civil protection means available amongst all the participating states. Any country inside or outside the Union affected by a major disaster can make an appeal for assistance through the MIC.

It acts as a communication hub at headquarters level between participating states, the affected country and despatched field experts. It also provides useful and updated information on the actual status of an ongoing emergency. Besides, every nation has its own mechanism to deal with disasters.

For example, we can take Australia. Natural disasters are part of life in Australia. Drought occurs on average every 3 out of 10 years and associated heatwaves have killed more Australians than any other type of natural disaster in the 20th century. Australia’s emergency management processes embrace the concept of the prepared community. The principal government agency in achieving this is Emergency Management Australia.

In Canada, Public Safety Canada is national emergency management agency. Each province is required to have legislation in place for dealing with emergencies, as well as establish their own emergency management agencies, typically called an “Emergency Measures Organisation” (EMO), which functions as the primary liaison with the municipal and federal level. Public Safety Canada coordinates and supports the efforts of federal organizations ensuring national security and the safety of Canadians. They also work with other levels of government, first responders, community groups, the private sector (operators of critical infrastructure) and other nations. Public Safety Canada’s work is based on a wide range of policies and legislation through the Public Safety and Emergency Preparedness Act which defines the powers, duties, and functions of PS are outlined.

Likewise, in Germany, the Federal Government controls the German Katastrophenschutz (disaster relief) and Zivilschutz (civil protection) programmes. The local units of German fire department and the Technisches Hilfswerk (Federal Agency for Technical Relief, THW) are part of these programmes & the German Armed Forces (Bundeswehr), the German Federal Police and the 16 state police forces (Landerpolizei) all have been deployed for disaster relief operations. Besides the German Red Cross, humanitarian help is dispensed by the Johanniter-Unfallhilfe, the German equivalent of the St. John Ambulance, the Malteser-V Hllfsdienst, the Arbeiter-Samariter-Bund, and other private organization, to cite the largest relief organizations that are equipped for large-scale emergencies.

In the Netherlands, the Ministry of the Interior and Kingdom Relations is responsible for emergency preparedness and emergency management on the national level and operates a National Crisis Centre (NCC). The country is divided into 25 safety regions (veiligheidsregio). Each safety region is covered by three emergency services: police, fire and ambulance. All regions operate according to the Coordinated Regional Incident Management System. Other services, such as the Ministry of Defence, water board(s) and Rijkswaterstaat, can have an active role in the emergency management process.

In New Zealand, however, responsibility for disaster management moves from local to national depending on the nature of the emergency or risk reduction programme. A severe storm may be manageable within a particular area, whereas a public education campaign will be directed by the central government. Within each region, local governments are unified into 15 Civil Defence Emergency Management Groups (CDEMGs). Every CDEMG is responsible for ensuring that the emergency management is as robust as possible. As local governments are overwhelmed by an emergency, pre-existing mechanism. Central government has the authority to coordinate the response through the National Crisis Management Centre (NCMC), operated by the Ministry of Civil Defence & Emergency Management (MCDEM). These structures are defined by regulation and best explained in The Guide to the National Civil Defence Emergency Management Plan, roughly equivalent to the US Federal Emergency Management Agency’s National Response Framework. In Russia, the Ministry of Emergency Situations (EMERCOM) is engaged in firefighting, Civil Defence, Search and Rescue, including rescue services after natural and human-made disasters.

The United Kingdom focussed on disaster management following the 2000 UK fuel protests, severe flooding in the same year and the 2001 United Kingdom foot-and-mouth crisis. This resulted in the creation of the Civil Contingencies Act 2004 (CCA) which defined some organizations as Category 1 and 2 Responders. These responders have responsibilities under the legislation regarding emergency preparedness and response. The CCA is managed by the Civil Contingencies Secretariat through Regional Resilience Forums and at the local authority level. Disaster Management training is generally conducted at the local level by the organizations involved in any response. This is consolidated through professional courses that can be undertaken at the Emergency Planning College.

Furthermore, diplomas, undergraduate and postgraduate qualifications can be gained throughout the country—the first course of this type was carried out by Coventry University in 1994. The Institute of Emergency Management is a charity, established in 1996, providing consulting services for the government, media and commercial sectors. The Professional Society of Emergency Planners is the Emergency Planning Society.

In the United States, Disaster and Catastrophe Planning have utilised the functional all-hazard approach for over 20 years, in which emergency managers develop processes (such as communication & warning or sheltering) rather than developing single-hazard/threat focussed plans (e.g., a tornado plan). Processes then are mapped to the hazards/threats, with the emergency manager looking for gaps, overlaps, and conflicts between processes. This has the advantage of creating a plan more resilient to novel events (because all common processes are defined), encourages planning done by the process owners who are the subject matter experts (e.g., the traffic management plan written by public works director, rather than the emergency manager), and focuses on processes (which are real, can be measured, ranked in importance, and are under our control)..

In the US, most disasters do not exceed the capacity of the local jurisdiction or the capacity that they have put in place to compensate such as memoranda of understanding (MoU) with adjacent localities. However, if the event becomes overwhelming local government, state emergency management (the primary government structure of the United States) becomes the controlling emergency management agency under the Department of Homeland Security (DHS), the Federal Emergency Management Agency (FEMA) is lead federal agency emergency management and supports in the US, but does not override the state authority.

The United States and its territories are covered by one of ten regions for FEMA’s emergency management purposes. If, during mitigation, it is determined that a disaster or emergency is terror-related or if declared an “Incident of National Significance”, the Secretary of Homeland Security will initiate the National Response Framework (NRF). Under this plan, the involvement of federal resources will be made possible, integrating with the local, county, state, or tribal entities. Management will continue to be handled at the lowest possible level utilizing the National Incident Management System (NIMS).

So far as India is concerned, the approach to disaster management had been confined to only responding fast and providing relief to the victims of a disaster till not long ago. A holistic approach to disaster management had been missing.

Now, as every part of the world has been treating itself as a part of the global society, an integrated approach has been adopted in India too. The relief-centric syndrome has been replaced by a holistic approach with emphasis on prevention, mitigation, and preparedness at least in principle. India has started making efforts with an aim to conserve developmental gains and to minimise losses to lives, livelihood, and property.

It has adopted a plan comprising six elements, i.e. Prevention, Mitigation and Preparedness in Pre-Disaster Phase and Response, Rehabilitation and Reconstruction in Post-Disaster Phase. Of the six elements, the first three comprise the Pre-Disaster exercises which were found non-existent during the Uttarakhand disaster. Advanced communication technology, though available with the Government, was not deployed either for preparing for it or for a quick response. There were no early warning systems, and once disaster struck, communication systems were paralyzed for several days as mobile networks collapsed.

A recent Comptroller and Auditor-General (CAG) report provide the appalling cue to it. It says that a series of half-completed projects and bungled attempts have resulted in systems that are defunct. We should, however, not remain aloof from the fact that the Uttarakhand tragedy can be repeated anywhere in the country, as 60 percent of India is prone to earthquakes of moderate to high intensity and 40 million hectares of land area is prone to floods.

Besides, no regard for law and environment in most part of the country makes the situation worse from the prevention point of view. Despite the Allahabad High Court order of 1998 regarding the prohibition of construction on 200 metres of land on either side of river banks across Uttarakhand, unlawful construction has been going on ever since. In addition, in this flood-prone area, there has been no restriction on the number of tourists, which flouts environment laws.

Uttarakhand’s population was one crore in 2011 whereas the number of tourists was 2.5 crore. Even today, most of the people have no knowledge regarding earthquake survivability and their ignorance leads to the mass casualty. People should be taught how to reduce the impact of a disaster and its long-term effects. They should be trained to indulge in relief activities in disasters like floods and earthquakes.

all about earth

In this highly informative video everything you ever wanted to know about planet earth is described in a nutshell.

All you should know about your planet earth.

Planet Earth is the home of every lifeform, known to us, in the universe. Its age is about 1/3 of the age of the universe and, admitted. It is a thing of beauty, a slightly squashed fair with a heavy metal core, and a lighter surface crust, wrapped in a thin sliver of sweet air to breathe, with vast oceans, fertile plains, magnificent mountains, fresh water rivers, streams, lakes and aquifers, orbiting a star which warms us, and gives us energy.

But how did our home come into existence,and what’s it made of?

4.6 billion years ago, Planet Earth was created from the remnants of dead stars, that collected in a giant, dirty gas cloud. The gas cloud became denser in its center, and formed an accretion disk. small particles started clumping together, and building larger and larger objects, until they form the objects we  all “Planets” today. This process took 10 to 20 million years, and is still not very well understood. At about this time, when the solar system was young and chaotic, a giant object, about as big as Mars, collided with our home. The impact was violent, and if the object had been more massive, it might have destroyed Earth. Materials from Earth were smashed out into orbit, and formed the Moon, which is the biggest satellite in relation to its planet in the solar system. At this  time, Earth was a hot hell, constantly being hit by asteroids, with seas of lava,  and a toxic atmosphere.

But something was about to change drastically. Earth cooled down. Water from the inside of the Earth wandered to the surface and rained down on Earth, only to vaporize again and become clouds. Millions of asteroids brought more and more water to our planet. All the water on Earth has about this volume compared to Earth.

Today, the surface of Earth is 71% water, and 29% land. 97.5% is saline water, while only 2.5% is fresh water. The Fresh water is 69% ice and snow, 30% are ground waters, and only about 1% make up the remaining ground waters.

But even this small part is mostly frozen. Only a tiny part of our water is actually lakes and rivers. and an even tinier part is bound in living things. So, gradually the Earth cooled down, and the surface formed a thin crust. But inside the earth, hot rock continue to swirl about, moving the crust from below and breaking it apart. This process is called “Plate Tectonics”, and is happening right now.

Interior of Earth

The crust of Earth consisted of separate giant plates that move around. As they meet, they crumble, and create mighty mountains. OR: violently plunge back down, deeper into Earth, creating deep trenches. That’s the way the highest place on Earth was formed: Mt.Everest, and the deepest: the Mariana Trench. From our perspective, Earth’s mountains and trenches are mighty indeed, but when you look at the Earth in cross-section, you can see how tiny they actually are. The part we stand on is the crust, which is about 50 kilometers thick, though it can vary between 5 and 70 kilometers By the way, the deepest hole ever drilled by man
is 12.262 kilometers deep.

After the crust, comes the mantle. It’s a silicate rocky shell, and about 2,900 kilometers thick. The mantle consists of the upper mantle, and the lower mantle.  The upper mantle has different regions, too. It’s upper part, which is viscous and carries the crust, is called the “Lithosphere.”

After that, there comes the “Asthenosphere,” which consists of less mobile, mostly solid material. The lower mantle reaches deep down to the outer core of  Earth. Earth’s outer core is a liquid layer of iron and nickel, about 2,266 kilometers thick. Temperatures vary from 4,000℃(7,232℉) to 5,700℃(10,292℉). And in the center, is the inner core. It’s mostly solid, a ball made of an iron-nickel alloy. with a radius of about 1,200 kilometers. 70% of the size of the moon, and about the temperature of the surface of the Sun. It is slowly growing at an estimated rate of about 1mm/year.

Now, for some respective, this small layer of crystallized melt products of former molten mantle, is where we live.

Earth’s Magnetic Field

Then, there’s Earth’s magnetic field. It’s an invisible phenomenon that diverts high energy particles coming from the Sun and other sources, allowing for a stable environment with comparatively little radiation impact on Earth.

But why is it there? Actually, we don’t really know a terrible lot about that. We know, it has something to do with the core of Earth. Inside this metal sphere, large electrical currents flow in complicated patterns.

They cause a magnetic field, that sort of stabilizes itself according to the laws of electrodynamics. This entire system is called the “Dynamo.”  But, don’t let us fool you into thinking we have it all figured out. Speaking of breathtaking information,

Have a Look at: What is the difference between meteors, meteorites, meteoroids and asteroids ? And what are comets ?

What about the airy stuff that surrounds us? Atmosphere

  • By volume, dry air consists mostly of Nitrogen, Oxygen, Argon, Carbon, a variable amount of water vapor, and small amounts of other gases. Humans are very dependent on the lowest layer of the atmosphere: the Troposphere – Where the weather is.
  • It’s 12 kilometers thick on average. Above that is the Stratosphere,which is where the ozone layer protects us from the sun’s most aggressive type of light.
  • Above that is the Mesosphere – the coolest place on Earth, with an average temperature around -85℃(-121℉). At about 80 kilometers up, the Thermosphere starts.
  • The transition to space is a fluent one, without clear borders, but humans decided that space starts here. At about 100 kilometers, Earth stops, and space begins, though the atmosphere extends a bit further.
  • In this region, we find the Ionosphere, the aurora borealis, and the ISS, and the outermost layer is the Exosphere, stretching up to 10,000 kilometers. It merges fluently with outer space, where there’s no atmosphere at all.
  • The atoms and molecules in this area are so far apart, that they can travel hundreds of kilometers without colliding with each other. Humans, in their present form, have only been around for 200,000 years, that’s 0.004% of Earth’s history.
  • Not long, really. and, here we are now, living in a thin, moist layer on a small, wet rock. We call this rock: Earth. It is the product of the universe’s deepest workings, the result of a constant process of creation and destruction, happening all of the universe, all the time, helped by chance, the laws of the universe and random events, we are really lucky.

Coral reefs

coral-reef

There exist a variety of ecosystem on the planet Earth and Coral reefs are one of them. The coral reef is an integral part of the marine environment as one-third of all marine fish species lives on coral reefs. They are held compactly underwater due to the secretion of calcium carbonate by corals. Polyps in a cluster form the basis of corals. Polyps belong to an animal group called Cnidaria. Stony structures of corals combine to form coral reefs. They are found in sub-tropical and tropical oceans.  Warm, clear and shallow waters are the most suitable for the formation of coral reefs. There also exist cold water corals in deep cold water where temperature varies from 39 -55 degrees Fahrenheit. They are often given the title of ‘tropical rainforests of the ocean ’ as like rainforests they form the part of the habitat for different marine species like fish, sponges, molluscs, crustaceans etc.

coral-reef

Coral has a symbiotic relationship with zooxanthellae, a microscopic algaes which live on coral and it provides assistance to coral in nutrient production through its photosynthetic activities. Corals consist of clear white tissues but they give a beautiful colorful appearance due to the presence of zooxanthellae which lives withing their tissues. Corals are of two types, hard and soft. Only hard corals are able to build reefs. Polyps grow and die leaving their limestone skeletons behind which helps in the building up of a reef. Coral reefs can be classified into fringing reefs that are continuous with the shore, patch reefs that are isolated and discontinuous, barrier reefs that run parallel to coastlines and arise from submerged ocean shelf platforms and atoll reefs that are circular or semi-circular in shape.

The great barrier reef of Australia is the largest warm water reef and Rost reef off Norway is the largest cold water reef. In India coral reefs are found in Andamans and Nicobar, Gulf of Kutch, Gulf of Mannar and Lakshadweep.

The coral reefs are of great importance as they form natural protective barriers against erosion and storm surge. They are the largest biological producer of calcium carbonate and they provide an underlying layer to mangroves and they are one of the most productive ecosystems of the marine environment.

Unfortunately, this ecosystem is facing a major threat to its existence in the form of climate change, mining, dredging, sediment loading, intensive fishing and thermal pollution. Both natural and anthropogenic events are disturbing the formation of coral reefs. Natural disturbances include violent storms, flooding, high and low extreme temperatures etc.

The most visible negative effect is in the form of coral bleaching. It refers to the paling or bleaching of the colour of corals when the density of zooxanthellae starts declining and concentration of photosynthetic pigment falls and if this phenomenon is prolonged , the population of this microscopic algae fails to recover and eventually the host coral dies.

In order to protect coral reefs, Marine Protected Areas (MPAs) are coming up and they are responsible for fishery management and habitat protection. There also exist Coastal Ocean Monitoring and Prediction system (COMAPS) which assess the health of coastal waters and pollution related issues.
