Nitrogen compounds are essential for life. They are needed to make many biological compounds including proteins, amino acids, DNA and ATP (the 'fuel source' of cells), without which no living organism could survive. Nitrogen is particularly important because it often limits food production, while high levels of N compounds in the environment lead to serious pollution problems. By supplying N fertilizers, farmers greatly improve their yields. This has been essential to feed the growing world population over the last century, with N fertilizers estimated to sustain ~3.5 billion people, almost half of humanity.While the increased manufacture and mobilization of reactive N sources can be seen as a great feat of 'geoengineering', there have been many unintended consequences. A growing human population needs more food, so more fertilizers, especially as we now eat more animal products per person. The result is a complex web of pollution issues, threatening water, air and soil quality, altering climate balance and impacting on ecosystems and human health. In addition to the loss of N from farms, other sources cannot be forgotten. These include air emissions from burning, and losses to water from sewage systems. Overall, human alteration of the global N cycle makes for a multi-issue problem that ranks alongside climate change as one of the great challenges of the 21st century. The European Nitrogen Assessment has estimated that N pollution alone causes 70-320 billion Euro per year of damage across the EU (Nature, 14 April 2011,472,159).Given the wide diversity of nitrogen loss pathways into the environment, there are many potential solutions. In a recent report 'Our Nutrient World' led by CEH for the United Nations Environment Programme (UNEP, launched Feb 2013), 10 key actions were identified which would contribute to better nutrient management, simultaneously helping to meet food security goals while reducing the pollution of air, land and water, with multiple benefits for ecosystems, climate and human health. However, 'Our Nutrient World' also identified that there is currently no global international agreement that links the many benefits and threats of nitrogen. As a result, there is also no coordinated scientific assessment and support process to quantify and demonstrate these linkages. This gap is now being addressed by the International Opportunities Fund (IOF) of the NERC through its support for a new endeavour "Pump priming to towards the International Nitrogen Management System" - or 'INMSpp' for short.The central idea is that a scientific support system is needed that can provide the evidence needed to show how joined-up management of the global nitrogen cycle will deliver multiple benefits, and to be able to evaluate options that policy makers may wish to consider. Already there is a developing ambition for INMS as reflected by the invitation from the UN Global Environment Facility (GEF) for the NERC Centre for Ecology and Hydrology (CEH) to work with UNEP to develop a concept to establish a future INMS approach. Ultimately this would be a major endeavour, linking indicators, models and datasets to allow evaluation of possible international agreements. The INMS pump priming project provides a key step towards this eventual goal. As one of the key challenges to establish model chains from source to impact to mitigation and adaptation the INMSpp project has taken on the task of working out how integrated global modelling of the nitrogen cycle should be developed. The project will bring together a global consortium to examine how models can be joined up to demonstrate the net benefits of better nitrogen management. This will be a key resource as the INMS approach is developed. The outcome is the prospect to show how linking up different international environmental agreements can build common ground, simultaneously supporting food and energy security and a cleaner environment.

氮化合物对生命至关重要。需要它们制作许多生物化合物，包括蛋白质，氨基酸，DNA和ATP（细胞的“燃料来源”），没有这些生物可以生存。氮尤其重要，因为它通常会限制粮食生产，而环境中的n个化合物的高水平导致严重的污染问题。通过供应氮肥，农民可以大大提高其产量。这对于养活上个世纪不断增长的世界人口至关重要，N肥料估计将维持约35亿人，几乎是人类的一半。虽然可以将反应性n来源的制造和动员增加是“地球工程”的重要壮举，但有很多意外的后果。不断增长的人口需要更多的食物，因此更多的肥料，尤其是当我们现在每人吃更多的动物产品时。结果是一个复杂的污染问题网络，威胁水，空气和土壤质量，改变气候平衡并影响生态系统和人类健康。除了农场丧失N之外，其他来源也不能忘记。其中包括从燃烧中的空气排放，以及污水系统中的水损失。总体而言，人类对全球n周期的改变使一个多问题的问题与气候变化一起排名为21世纪的巨大挑战之一。欧洲氮评估估计，仅氮污染就会在整个欧盟造成700-32亿欧元的损失（自然，2011年4月14日，2011年4月14日，159年）。将氮损失途径的广泛多样性带入了环境，有许多潜在的解决方案。在CEH为联合国环境计划（UNEP，2013年2月启动）领导的最新报告“我们的营养世界”中，确定了10个关键行动，这将有助于更好的营养管理，同时帮助实现粮食安全目标，同时减少空气，土地和水的污染，并为生态系统，环境和人类健康带来多重益处。但是，“我们的营养世界”还确定，目前尚无全球国际协议可以将氮的许多好处和威胁联系起来。结果，也没有协调的科学评估和支持过程来量化和证明这些联系。 NERC的国际机会基金（IOF）现在通过支持新的“向国际氮管理系统启动启动”（或简称'INMSPP'）来解决这一差距。中心想法是，需要进行科学支持系统，以便为全球氮气循环提供能够提供多种福利的能力，以便能够提供多种福利，以便能够评估多个能力的选择，以便能够提供多种效益，以便能够评估多重福利。正如联合国全球环境设施（GEF）邀请NERC生态与水文学中心（CEH）与UNEP合作开发一个概念以建立未来的INMS方法的邀请所反映的INM的发展野心。最终，这将是一项重大努力，将指标，模型和数据集链接起来，以评估可能的国际协议。 INMS泵启动项目为最终目标提供了关键步骤。作为建立从源到缓解和适应的模型链的关键挑战之一，INMSPP项目已承担了如何确定应如何开发氮循环的整体全球建模的任务。该项目将汇集一个全球财团，以研究如何连接模型以证明更好的氮管理的净益处。随着INM方法的开发，这将是一个关键资源。结果是展示如何联系不同的国际环境协议可以建立共同点，同时支持食品和能源安全以及更清洁的环境的前景。
