The hub will investigate Nitrogen flux and agriculture in Asia

£20 million to tackle nitrogen pollution

 

The UK Government today (January 22) announces its commitment to fund a major international research programme to tackle the challenge that nitrogen pollution poses for the environment, food security, human health and the economy in South Asia.

The South Asian Nitrogen Hub, a partnership led by the UK’s Centre for Ecology & Hydrology, including PML, and comprising around 50 organisations from across the UK and South Asia, will be established with funding from UK Research and Innovation (UKRI) under its Global Challenges Research Fund (GCRF). The Hub will be awarded £19.6 million over the next five years, comprising £17.1 million from URKI and £2.5m from UK and international partners, including the South Asia Cooperative Environment Programme (SACEP). Contributions in-kind worth a further £7 million are being provided by partners of the UKRI GCRF South Asian Nitrogen Hub.

The Hub is one of 12 GCRF hubs being announced today by UKRI to address intractable challenges in sustainable development. The interdisciplinary hubs, between them, will work across 85 countries with governments, international agencies, partners and NGOs on the ground in developing countries and around the globe, to develop creative and sustainable solutions that help make the world safer, healthier and more prosperous.

Nitrogen pollution comes in many forms, with multiple impacts – for humans, animals and plant life. 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; while nitrous oxide (N2O) is a greenhouse gas that depletes the ozone layer. Nitrate from chemical fertilizers, manure and industry pollutes rivers and seas, posing a health risk for humans, fish, coral and plant life.

The UKRI GCRF South Asian Nitrogen Hub 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. The Hub’s recommendations will support cleaner and more profitable farming, as well as industrial recycling of nitrogen, fostering development of a cleaner circular economy for nitrogen.

Nitrogen pollution presents significant barriers to achieving United Nations Sustainable Development Goals on: Zero Hunger, Climate Action, Good Health & Well-being, Clean Water & Sanitation, Affordable & Clean Energy, Life Below Water, Life on Land, No Poverty, Responsible Consumption & Production, and Decent Work & Economic Growth. The Hub will support progress towards meeting SDGs, address barriers to change, and demonstrate the economic benefits of tackling nitrogen pollution. The involvement of UN Environment, SACEP and South Asian governments will ensure that the outcomes are shared widely as a basis to accelerate uptake of the most promising solutions.

Science and Universities Minister Chris Skidmore, says: “The UK has a reputation for globally influential research and innovation, and is at the centre of a web of global collaboration – showing that science has no borders. We have a strong history of partnering with other countries – over 50 per cent of UK-authored research involves collaborations with international partners. The projects being announced today reinforce our commitment to enhance the UK’s excellence in innovation at home and around the world, driving high-skilled jobs, economic growth and productivity as part of the modern Industrial Strategy.

Professor Mark Sutton of the Centre for Ecology & Hydrology, an international nitrogen expert who will head up the UKRI GCRF South Asian Nitrogen Hub, says: “As a global society, we struggle with the intractable problems of air pollution, climate change and declining water quality, biodiversity and health. However, better nitrogen management will provide solutions to all of them and offers a triple win – for the economy, health and environment. Joining up across the nitrogen cycle will catalyse change for a cleaner, healthier and more climate-resilient world.”

Dr Yuri Artoli, of PML's Marine Ecosystems Models and Predictions group, says: “Using the coupled model system NEMO-ERSEM, we will try to address the mystery of why, despite the high load of nitrogen pollution discharged by the big rivers, there is little evidence of hypoxia in the South Asian seas, a typical indicator of high nitrogen polluted marine environment. We will be working together with terrestrial and atmospheric modellers to build a full nitrogen cycle model. This will be used in the project to map impacts of the nitrogen pollution on different aspects of the South Asian sub-continent, from water quality, to corals, to fishery.”
