India's air pollution: 2 million+ premature deaths annually
India's air pollution is a serious environmental issue, with the country ranking fifth in the world for poor air quality in 2019. A study based on 2016 data revealed that at least 140 million Indians breathe air that is 10 times or more over the World Health Organisation's (WHO) safe limit. This is reflected in the country's high levels of pollution-related deaths.
According to a Lancet study, there were nearly 1.67 million deaths in India attributed to worsening air pollution in 2019. However, a more recent Lancet report from 2022 put this number at over 2 million premature deaths from pollution in 2019, with nearly 1.6 million of these caused by air pollution alone. This is supported by a Health Effects Institute report, which stated that over a million Indians die prematurely each year due to air pollution.
The main causes of India's air pollution are industrial and vehicular emissions, construction dust, waste burning, and the use of wood and dung for cooking and heating. More specifically, 51% of India's air pollution is caused by industrial sources, 27% by vehicles, 17% by crop burning, and 5% by other sources. In rural areas, the burning of biomass for cooking and warmth is a significant contributor to air pollution. Fuelwood and biomass cakes are used in over 100 million households, with the carbon-containing gases released being much more reactive than cleaner fuels. The smoke and pollutants produced by these cookstoves are five times higher than if coal were burned. In urban areas, the primary sources of pollution are vehicles and industry.
The consequences of air pollution in India are dire, with the country's poor air quality causing serious health problems. Air pollution is linked to respiratory and cardiovascular diseases, including asthma, bronchitis, COPD, lung cancer, and heart attacks. The impact of air pollution is also economic, with an estimated loss of US$28.8 billion in 2019. Furthermore, the average life expectancy in India would increase by 1.7 years if exposure to ambient particulate matter was limited to national minimum recommendations.

Water contamination: 500 districts with iron-contaminated water in 2022
India faces severe air and water pollution, which has detrimental effects on the health and economy of the country. In 2019, India was ranked as the fifth most polluted country in the world, with 21 out of the 30 most polluted cities.
Water contamination is a significant issue in India, impacting the lives of millions. In 2022, groundwater in 491 Indian districts showed high concentrations of iron, making it the primary water pollutant in the country. This issue is further exacerbated by the presence of other toxic metals in the groundwater, such as arsenic, which was found in over 200 districts. Iron contamination in groundwater has been a long-standing problem in India, with states like Rajasthan, Karnataka, and Gujarat being particularly affected. In 2010, it was reported that 28 out of 9 districts in Rajasthan had high iron content in their groundwater, while 21 out of 31 districts in Karnataka were contaminated with iron.
The main sources of water pollution in India include untreated sewage, agricultural runoff, and unregulated small-scale industries. Rivers such as the Yamuna, Ganga, and Godavari are among the most coliform-polluted water bodies in the country, posing significant health risks to those who depend on them. The Ganges River, considered holy by Hindus, has around 2 million people bathing in it daily, despite the high levels of pollution.
The Indian government has acknowledged the issue of water contamination and has taken steps to address it. In 2009, the National River Conservation Directorate (NRCD) was established under the Environment Protection Act, 1986, to improve water quality and conserve rivers. Additionally, the National Water Quality Monitoring Network, established by the Central Pollution Control Board, comprises 1,429 monitoring stations across 28 states and 6 Union Territories, working to monitor and improve water quality.
While India has made efforts to combat water contamination, the issue remains a significant challenge. The complex bureaucracy and lack of infrastructure have hindered the effective implementation of policies and solutions.

Land degradation: 30% of India's land degraded, 60% in Rajasthan
India is facing a severe air pollution crisis, with 21 of the world's 30 most polluted cities in 2019. The country has 1.35 billion people, and air pollution causes 1.67 million premature deaths per year—more than COVID-19. The main sources of air pollution in India are industrial and vehicular emissions, construction dust, and the burning of crops and waste.
In addition to air pollution, India is also grappling with land degradation, which affects approximately 30% of its land area. Land degradation has severe implications for natural resource-based livelihood systems, food security, economies, biodiversity, and community well-being. India has implemented various initiatives to tackle this issue, including the National Action Plan for Climate Change and afforestation programs like the Green India Mission. Despite these efforts, land degradation remains a significant challenge.
Rajasthan, a state in India, is particularly vulnerable to land degradation, with 60% of its land classified as degraded. The primary cause of degradation in Rajasthan is wind erosion, which is prevalent in the state's arid and semi-arid zones. Other factors contributing to land degradation in Rajasthan include vegetation degradation, water erosion, and localised salinity issues. The government has set a target of achieving land degradation neutrality by 2030 and is working towards implementing sustainable soil and water management solutions.
Land degradation in Rajasthan has severe consequences for the state's agriculture and environment. The degradation affects soil health, water quality, and availability, impacting agricultural productivity and the livelihoods of farmers, especially small, marginalised, and women farmers. It also exacerbates the problems of desertification and drought, threatening India's agrifood systems and food security.
To address land degradation in Rajasthan, the government, in collaboration with the Food and Agriculture Organization of the United Nations (FAO), has undertaken several initiatives. The FAO's Global Environment Facility (GEF)-funded projects, such as the GEF-6 Green-Ag project, aim to mainstream biodiversity conservation, climate change mitigation, and sustainable land management practices into Indian agriculture. These projects are implemented across multiple states, including Rajasthan, to achieve global environmental benefits while strengthening rural livelihoods and ensuring food and nutrition security.

Top sources of air pollution: industry, vehicles, crop burning, domestic cooking
India has a serious air pollution problem. Of the 30 most polluted cities in the world, 21 were in India in 2019. A study based on 2016 data found that at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit. India's particulate air pollution comes from industrial and vehicular emissions, construction dust and debris, waste burning, and the use of wood and dung for cooking and heating.
Industry
More than half of India's air pollution (51%) is caused by industrial pollution. The widespread use of coal to generate electricity in India has been linked to increasing emissions.
Vehicles
Vehicular emissions are responsible for 27% of India's air pollution. The use of adulterated fuel blends in some Indian taxis and auto-rickshaws increases emissions of harmful pollutants from vehicles, worsening urban air pollution.
Crop burning
Crop residue burning in agriculture fields is a major source of smoke, smog and particulate pollution. It is a cheaper alternative to mechanical tilling. From 2003 to 2019, agricultural residue burning caused 44,000-98,000 premature deaths annually. Small interventions, such as burning one hour earlier in the day, may provide broad public health benefits.
Domestic cooking
Domestic cooking is responsible for 5-7% of India's air pollution. Traditional fuel (fuelwood, crop residue and dung cake) dominates domestic energy use in rural India, accounting for about 90% of the total. In urban areas, this type of fuel constitutes about 24% of the total. Fuelwood and biomass cakes are used for cooking and general heating needs. These are burnt in cook stoves known as chulhas, which are present in over 100 million Indian households and are used two to three times a day, daily. The carbon-containing gases released from biomass fuels are many times more reactive than cleaner fuels such as liquefied petroleum gas.

Solutions: stricter regulations, renewable energy, public transport
India has a serious problem with air pollution. In 2019, 21 of the 30 most polluted cities in the world were in India. A study based on 2016 data found that at least 140 million people in India breathe air that is 10 times or more over the WHO safe limit. The main contributors to India's air pollution include industrial and vehicular emissions, construction, dependence on thermal power, waste burning, and the use of wood and dung for cooking and heating by low-income and rural households.
To combat this issue, India could implement stricter regulations to reduce industrial and vehicular emissions. This could include enforcing existing regulations, such as the Air (Prevention and Control of Pollution) Act, more effectively, and introducing new standards and policies to limit emissions from vehicles and industry.
Another solution is to promote renewable energy sources such as wind, solar, biofuel, biogas, and hydrogen fuel cells. India has already made progress in this area, with the renewable energy sector contributing a record 13.4% to the country's cumulative power production as of August 2018. The development and deployment of renewable energy technologies are crucial to reducing India's dependence on fossil fuels, particularly coal and oil, which currently supply close to 74% of the country's energy demand.
In addition to stricter regulations and renewable energy, investing in and promoting public transport could also help reduce pollution in India. Public transport can reduce the number of private vehicles on the road, thereby decreasing vehicular emissions. Additionally, ensuring that public transport vehicles use clean fuels and are well-maintained can further reduce emissions. Addressing the issue of fuel adulteration in taxis and auto-rickshaws by enforcing fuel quality standards and removing financial incentives for blending cheaper hydrocarbons can also contribute to improving air quality.
Furthermore, India can implement initiatives such as the Great Green Wall of Aravalli, a 1,600-kilometer-long and 5-kilometer-wide ecological corridor aimed at combating pollution. This project involves planting 1.35 billion new native trees over a decade, connecting the Aravalli range to the Shivalik hill range. Such initiatives can help absorb pollutants and improve air quality while also providing ecological benefits.
