Ecological restoration India

India is one of the most biodiverse regions and is home to a large variety of wildlife. It is one of the 17 megadiverse countries and includes three of the world's 36 biodiversity hotspots – the Western Ghats, the Eastern Himalayas, and the Indo-Burma hotspot.

About 24.6% of the total land area is covered by forests. It has various ecosystems ranging from the high altitude Himalayas, tropical evergreen forests along the Western Ghats, desert in the north-west, coastal plains and mangroves along the peninsular region. India lies within the Indomalayan realm and is home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.2% of flowering plant species.

Human encroachment, deforestation and poaching are significant challenges that threaten the existence of certain fauna and flora. Government of India established a system of national parks and protected areas in 1935, which have been subsequently expanded to nearly 1022 protected areas by 2023. India has enacted the Wildlife Protection Act of 1972 and special projects such as Project Tiger, Project Elephant and Project Dolphin for protection of critical species.

Air pollution in India is a serious environmental issue. Of the 30 most polluted cities in the world, 21 were in India in 2019. As per a study based on 2016 data, at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit and 13 of the world's 20 cities with the highest annual levels of air pollution are in India. The main contributors to India's particulate air pollution include industrial and vehicular emissions, construction dust and debris, dependence on thermal power for electricity, waste burning, and use of wood and dung by low-income and rural households for cooking and heating. 51% of India's air pollution is caused by industrial pollution, 27% by vehicles, 17% by crop burning and 5% by other sources. Air pollution contributes to the premature deaths of 2 million Indians every year. Emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. In autumn and spring months, large scale crop residue burning in agriculture fields – a cheaper alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution. India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest greenhouse gas producer after China and the United States. A 2013 study on non-smokers has found that Indians have 30% weaker lung function than Europeans.

The Air (Prevention and Control of Pollution) Act was passed in 1981 to regulate air pollution but has failed to reduce pollution because of poor enforcement of the rules.

In 2015, Government of India, together with IIT Kanpur launched the National Air Quality Index. In 2019, India launched 'The National Clean Air Programme' with tentative national target of 20%-30% reduction in PM2.5 and PM10 concentrations by 2024, considering 2017 as the base year for comparison. It will be rolled out in 102 cities that are considered to have air quality worse than the National Ambient Air Quality Standards. There are other initiatives such as a 1,600-kilometre-long and 5-kilometre-wide The Great Green Wall of Aravalli green ecological corridor along Aravalli range from Gujarat to Delhi which will also connect to Shivalik hill range with planting of 1.35 billion (135 crore) new native trees over 10 years to combat the pollution. In December 2019, IIT Bombay, in partnership with the McKelvey School of Engineering of Washington University in St. Louis, launched the Aerosol and Air Quality Research Facility to study air pollution in India. According to a Lancet study, nearly 1.67 million deaths and an estimated loss of US$28.8 billion worth of output were India's prices for worsening air pollution in 2019.

Peepal Baba or Swami Prem Parivartan is an environmentalist who along with his team has planted over 20 million trees in 202 districts across 18 states in India. He was born to a doctor of Indian Army on 26 January 1966 in Chandigarh, India. His English teacher inspired him at the age of 11 to plant trees in 1977. He is the founder of Give Me Trees Trust which was later registered as a non-governmental organisation in 2011. He took asceticism in 1984 from Osho Rajneesh, who gave him the name "Swami Prem Parivartan". Now he also is an inspiration for others interested in the Nature.

Jadav "Molai" Payeng (born 31 October 1959) is an environmental activist and forestry worker from Majuli, popularly known as the Forest Man of India. Over the course of several decades, he has planted and tended trees on a sandbar of the river Brahmaputra turning it into a forest reserve. The forest, called Molai forest after him, is located near Kokilamukh of Jorhat, Assam, India and encompasses an area of about 1,360 acres / 550 hectares. In 2015, he was honoured with Padma Shri, the fourth highest civilian award in India. He was born in the indigenous Mising tribe of Assam.
