The '''environment of India''' comprises some of the world's most [[Biodiversity|biodiverse]] ecozones. The [[Deccan Traps]], [[Gangetic Plains]] and the [[Himalayas]] are the major geographical features. The country faces different forms of pollution as its major environmental issue and is more vulnerable to the effects of [[climate change]] being a [[Developing country|developing nation]]. India has laws protecting the environment and is one of the countries that signed the [[Convention on Biological Diversity]] (CBD) treaty. The [[Ministry of Environment, Forest and Climate Change]] and each particular state forest departments plan and implement environmental policies throughout the country.

India has some of the world's most [[biodiversity|biodiverse]] ecozones—desert, high mountains, highlands, tropical and temperate forests, swamplands, plains, grasslands, areas surrounding rivers and an island archipelago. It hosts three [[biodiverse hotspot]]s: the [[Western Ghats]], the [[Himalayas]] and the [[Indo-Burma]] region. These hotspots have numerous [[endemic (ecology)|endemic]] species.<ref name="TERI website">[http://www.teriin.org/biodiv/hotspot.htm] {{webarchive|url=https://web.archive.org/web/20051109182255/http://www.teriin.org/biodiv/hotspot.htm|date=9 November 2005}}</ref>

In 1992, around 7,43,534 km<sup>2</sup> of land in the country was under forests and 92 percent of that belonged to the government. Only 22.7 percent was forested compared to the recommended 33 percent by the National Forest Policy Resolution (1952). Majority of it are broad-leaved [[deciduous]] trees which comprise one-sixth ''[[Sal (tree)|sal]]'' and one-tenth [[teak]]. [[Coniferous forest|Coniferous]] types are found in the northern high altitude regions and comprise [[pine]]s, [[juniper]]s and ''[[Deodar forests|deodars]]''.<ref>{{Cite book|url=https://books.google.com/books?id=yUtagKhyt9MC|title=Geography of India|last1=Nag|first1=Prithvish|last2=Sengupta|first2=Smita|date=1992-01-01|publisher=Concept Publishing Company|isbn=9788170223849|page=79|language=en}}</ref>

There are over 17000 species of flowering plants in India, which account for six percent of the total plant species in the world. India comprises seven percent of world's flora. Wide range of climatic conditions in India gave rise to rich variety of flora. India covers more than 45,000 species of flora, out of which several are endemic to the region. India is divided into eight main floristic regions: North-Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganga plain, the Deccan, the Malabar and the Andamans.{{sfn|Majid|2014|p=5.2}}

=== Geography ===
{{Main|Geography of India}}
India lies on the [[Indian Plate]], the northern portion of the [[Indo-Australian Plate]], whose [[continental crust]] forms the [[Indian subcontinent]]. The country is situated north of the equator between 8°4' and 37°6' north latitude and 68°7' and 97°25' east longitude. It is the [[List of countries and outlying territories by total area|seventh-largest country in the world]], with a total area of {{convert|3287263|km2|mi2|0}}.<ref name=indiaEB>{{cite encyclopedia| title=India|encyclopedia=Encyclopædia Britannica|url=http://www.britannica.com/EBchecked/topic/285248/India|access-date=17 July 2012}} Total area excludes disputed territories not under Indian control.</ref> India measures {{convert|3214|km|mi|0|abbr=on}} from north to south and {{convert|2933|km|mi|0|abbr=on}} from east to west.

The Indian plate and [[Eurasia]] collided between 40 and 60 million years ago according to four observations, one being that there is no mammalian fossil record in India from around 50 million years ago.<ref>{{Cite journal|last=Molnar|first=Peter|date=1986|title=Geological History and Structure of the Himalaya|url=http://www.colorado.edu/geolsci/faculty/molnarpdf/1986AmerSci.Geology-Himalaya.pdf|journal=American Scientist|volume=74|issue=2|page=151|access-date=22 March 2016|archive-url=https://web.archive.org/web/20160605135623/http://www.colorado.edu/GeolSci/faculty/molnarpdf/1986AmerSci.Geology-Himalaya.pdf|archive-date=5 June 2016|url-status=dead|df=dmy-all|bibcode=1986AmSci..74..144M}}</ref> On its way, the Indian plate passed over the [[Reunion hotspot]] which led to volcanic activity, thus forming the [[Deccan Traps]]. Its collision with the Eurasian plate led to the rise of the [[Himalayas]] and the continuous tectonic activity still makes it an earthquake prone area.

The climate comprises a wide range of weather conditions across a vast geographic scale and varied topography, making generalisations difficult. Given the size of India with the Himalayas, Arabian Sea, Bay of Bengal and the Indian Ocean, there is a great variation in temperature and precipitation distribution in the subcontinent.{{sfn|Majid|2014|pp=4.27, 4.15}} Based on the [[Köppen climate classification|Köppen system]], where the mean monthly temperature, mean monthly rainfall and mean annual rainfall are considered, India hosts six major climatic subtypes, ranging from arid desert in the west, alpine tundra and glaciers in the north, and humid tropical regions supporting rainforests in the southwest and the island territories. Many regions have starkly different [[microclimate]]s. The [[Indian Meteorological Department]] divides the seasons into four: Winter (mid-December to mid-March), Summer (mid-March to May), Rainy (June to September), and Retreating Monsoon (October to mid-December).{{sfn|Majid|2014|pp=4.27, 4.15}}

== Issues ==
{{Main|Environmental issues in India}}
[[File:MEHTAB BAGH - TAJ MAHAL.jpg|alt=|thumb|[[Air pollution in India]] is a major environmental issue. Shown above is the Taj Mahal blanketed by smog.]]
Pollution is one of the main environmental issues in India.
* Water pollution [[Water pollution in India|is a major concern in the country]]. The major sources of water pollution are domestic, industrial, agricultural and shipping waste waters.{{sfn|Singh|Singh|Mohanka|2007|pp=327}} The largest source of water pollution in India is untreated [[sewage]]. Other sources of pollution include [[agricultural runoff]] and unregulated small scale industry. Most rivers, lakes and surface water are polluted.
* Land pollution: The main causes of soil (or land) pollution is [[soil erosion]], excessive use of chemical fertilisers and pesticides, accumulation of solid and liquid waste, forest fires, and water-logging. It can be reduced by judicious use of chemical fertilisers and pesticides and treatment of effluents before being used for irrigation.{{sfn|Majid|2014|pp=17.23–17.24}} Due to increasing population and enhanced food grains consumption, more and more rain fed crop lands are brought under intensive cultivation by ground and surface water irrigation. The irrigated land is losing gradually its fertility by converting into saline alkali soil.
* [[Air pollution in India|Air pollution in the country]] is another concern. A major source is the matter released by the combustion of [[fossil fuels]]. Airborne particles like soot, fumes and dust are potentially harmful depending on the pollutant's chemical and physical structure. They can affect climate and reduce scattering of solar radiation in the atmosphere.{{sfn|Singh|Singh|Mohanka|2007|pp=231–232, 300}}
* [[Noise pollution]]: This can be defined as the state of discomfort or stress caused by unwanted high intensity sound. It increases in proportion to urbanisation and industrialisation.{{sfn|Majid|2014|pp=17.23–17.24}}

===Climate change===
{{Further|Effects of global warming on South Asia}}

Being a developing nation, India is more vulnerable to the effects of [[climate change]] due to its dependence on climate-sensitive sectors like agriculture and forestry.<ref name=":0">{{Cite book|url=https://books.google.com/books?id=fvP-q_NSZUIC|title=Climate Change and India: Vulnerability Assessment and Adaptation|last=Shukla|first=P. R.|date=2003-01-01|publisher=Universities Press|isbn=9788173714719|pages=12, 13, 21|language=en}}</ref> Low per capita incomes and small public budgets also lead to low financial adaptive capacity.<ref name=":0" /> The nation is vulnerable to the immediate socio-economic effects of climate change. A 2002 study indicated that the temperature over the country increased at around 0.57° per 100 years.<ref name=":0" />

Inadequate infrastructure also means that people are more exposed, and less resilient, to climate change. For example, as of 2015, only 124 million Indians were connected to a sewer and 297 million to a septic tank.<ref>{{Cite web|url=https://washdata.org/data#!/ind|title=Joint Monitoring Programme|last=WHO and UNICEF|date=2015|website=washdata.org|language=en|access-date=2018-04-10}}</ref> The remainder depend on pit latrines or open defecation, which creates major risks of waterborne disease during floods - which will become more frequent and severe with climate change. These risks are more severe in urban areas, where the higher density of people means that basic infrastructure options might not be adequate. Additionally, many Indian megacities are in floodplains and deltas, and will therefore be very exposed to climate hazards such as sea level rise, storm surges and cyclones.<ref>{{Cite journal|last=Cruz, RV, Harasawa H, Lal M, Wu S, Anokhin Y, Punsalmaa B, Honda Y, Jafari M, Li C, HuuNinh N|date=2007|title=Asia|url=https://www.ipcc.ch/publications_and_data/ar4/wg2/en/ch10.html|journal=Climate Change 2007: Impacts, Adaptation and Vulnerability, Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change|pages=469–506|access-date=10 April 2018|archive-url=https://web.archive.org/web/20180311085159/http://www.ipcc.ch/publications_and_data/ar4/wg2/en/ch10.html|archive-date=11 March 2018|url-status=dead}}</ref>

Although India still has low average incomes per person, the country is now the third largest [[List of countries by carbon dioxide emissions|emitter of greenhouse gas emissions]] after China and the USA. The central government has pledged to reduce the emission intensity of [[Gross domestic product|Gross Domestic Product]] by 20-25%, relative to 2005 levels, by 2020. India has also made major pledges to expand its [[renewable energy]] supply, enhance energy efficiency, build mass transit and other measures to reduce its emissions.<ref>{{Cite web|url=http://www4.unfccc.int/ndcregistry/PublishedDocuments/India%20First/INDIA%20INDC%20TO%20UNFCCC.pdf|title=India's Intended Nationally Determined Contribution: Working Towards Climate Justice|date=2015}}</ref> There is evidence that many of these climate actions could generate substantial benefits in addition to reducing India's carbon footprint. Many low-carbon measures are economically attractive, including more efficient air conditioners, parking demand management, [[gasification]] and vehicle performance standards.<ref>{{Cite journal|last=Colenbrander|first=S|date=2017|title=Can low-carbon urban development be pro-poor?

== Conservation ==
{{Main|Conservation in India}}

===Protected areas===
{{Main|Protected areas of India}}
In 2009, around 4.8 percent of the total area of the country were designated as protected areas. That comprised 100 national parks, 514 sanctuaries, 41 conservation reserves and four community reserves.<ref name=":1" />

===Policy and law===
{{Main|Environmental policy of the Government of India}}In the [[Directive Principles in India|Directive Principles]] of State Policy, Article 48 says "the state shall endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country"; Article 51-A states that "it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers and wildlife and to have compassion for living creatures."{{sfn|Singh|Singh|Mohanka|2007|p=116–118}}

India is one of the parties of the [[Convention on Biological Diversity]] (CBD) treaty. Prior to the CBD, India had different laws to govern the environment. The [[Wildlife Protection Act, 1972|Indian Wildlife Protection Act 1972]] protected the biodiversity. In addition to this act, the government passed the [[Environment Protection Act, 1986|Environment (Protection) Act 1986]] and Foreign Trade (Development and Regulation) Act 1992 for control of biodiversity.<ref name=":1">{{Cite book|url=https://books.google.com/books?id=obbhCgAAQBAJ|title=Deliberating Environmental Policy in India: Participation and the Role of Advocacy|last=Ganguly|first=Sunayana|date=2015-11-06|publisher=Routledge|isbn=9781317592235|pages=58–59|language=en}}</ref>

== Environmentalism ==
In 1973, the government launched [[Project Tiger]], a conservation program aimed at protecting the national animal, the tiger. Its population reached as low as 2000 in 1970. Human population growth, cultivation of forest land and mainly hunting were the key factors for this decline. Aided by the [[World Wildlife Fund]] (WWF) and the [[International Union for Conservation of Nature]] (IUCN), Indian conservationists were instrumental in getting the government to ban hunting and set aside national parks. Project Tiger further served as a model for protecting endangered species like the [[Indian elephant]] and [[Indian rhinoceros|rhinoceros]].<ref name=":2">{{Cite book|url=https://books.google.com/books?id=fQxSxT_yWwYC|title=How Much Should a Person Consume?: Environmentalism in India and the United States|last=Guha|first=Ramachandra|date=2006-01-01|publisher=University of California Press|isbn=9780520248038|pages=35, 54, 55, 59|language=en}}</ref> Around that year, after a protest in a village by the locals against loggers sent by a company, by threatening to hug the trees, similar protests got triggered, collectively known as the [[Chipko movement|Chipko Movement]]. In the same year, the National Committee for Environmental Protection and Control was formed; in 1980, a department for Environment and finally five years later the [[Ministry of Environment, Forest and Climate Change]] was formed.
