UK to Support Nitrogen Research in India

• 25 Jan 2019

The United Kingdom will fund the South Asian Nitrogen Hub (SANH), a group of 50 institutions to assess and study the quantum and impact of “nitrogen pollution” in South Asia.

• Eighteen research institutions in India are the part of SANH which will study the impacts of the different forms of pollution to form a “coherent picture” of the nitrogen cycle.
  
  • In particular, it will look at nitrogen in agriculture in eight countries — India, Pakistan, Bangladesh, Nepal, Afghanistan, Sri Lanka, Bhutan and Maldives.
• This is a five-year programme established with funds from the UK Research and Innovation (UKRI) under its Global Challenges Research Fund (GCRF).

Global Challenges Research Fund

• The Global Challenges Research Fund (GCRF) is a £1.5 billion fund announced by the UK Government in late 2015 to support cutting-edge research that addresses the challenges faced by developing countries.
• GCRF forms part of the UK’s Official Development Assistance (ODA) commitment, which is monitored by the Organisation for Economic Cooperation and Development (OECD).

Nitrogen Pollution

• Nitrogen constitutes 78% of Earth's air. In the form of gas it is colourless, odourless and generally considered as inert gas. In aqueous form also it is colourless and odourless.
  • Nitrogen makes plants grow and is an essential component for life.
• Nitrogen is potent greenhouse gas. Nitrous oxide (N₂O) is 300 times more potent green house gas than carbon dioxide.
• Nitrogen pollution is caused by emission of excess of Nitrogen from the use of chemical fertilisers, livestock manure and burning fossil fuels.
• Gases such as ammonia (NH₃) and nitrogen dioxide (NO₂) contribute to poor air quality and can aggravate respiratory and heart conditions, leading to millions of premature deaths across the world.
• Nitrate from chemical fertilisers, manure and industry pollutes the rivers and seas, posing a health risk for humans, fish, coral and plant life.
• Other than air pollution, nitrogen is also linked to the loss of biodiversity, the pollution of rivers and seas, ozone depletion, health, economy, and livelihoods.

Need of the Study

• According to a study, nitrogen emissions in India grew at 52% from 1991 to 2001 and 69% from 2001 to 2011.

• The planetary boundary of N (nitrogen) is set at 44 Tg (Tera-grams) per year globally and current application of N, primarily through fertiliser usage, is about 150 Tg N per year.
  • Planetary boundary is the limits of the earth within which humans can thrive.
• Specially in case of South Asia, high doses of fertiliser input of nitrogen to agriculture combined with low nitrogen-use efficiency means that research on nitrogen pollution must be a priority. This is emphasised by the scale of nitrogen subsidies across South Asia at around $10 billion per year.
