This volume provides a unique collection of contributions
addressing both the 'too much' and 'too little' sides of the
nitrogen story. Building on analyses started at the 6th
International Nitrogen Conference, Kampala, the book explores the
idea of 'just enough nitrogen': sufficient for sustainable food
production, but not so much as to lead to unsustainable pollution
and climate problems. The range of nitrogen threats examined,
solutions evaluated and science-policy analyses presented here has
provided the foundation to agree the 'Kampala Statement-for-Action
on Nitrogen in Africa and Globally,' as reported in this volume.
Humanity today faces unprecedented challenges: How to feed a
growing population? How to reduce air pollution, water pollution
and climate change? How to handle regional differences in an era of
increasing globalization? These questions are at the heart of this
edited volume which examines the multi-dimensional nature of the
global nitrogen challenge. While humans have massively altered the
nitrogen cycle, the consequences have become polarized. Some
regions have too much nitrogen, associated with pollution and
wasteful use of a valuable resource, while other regions have too
little nitrogen, leading to constraints on food production and
depletion of soil nutrient stocks. The volume provides a unique

little' sides of the nitrogen story. Building on analyses started

are now informing actions by the International Nitrogen Initiative
(INI) in working with the United Nations Environment Programme and
others to establish the International Nitrogen Management System
(INMS). A key outcome has been to catalyse development of the first
Resolution on Sustainable Nitrogen Management, as adopted by the
fourth UN Environment Assembly (UNEA/EA.4/Res.14). The work is
written for researchers and policy makers and all those interested
in seeing how sustainable nitrogen management can contribute to
meeting many of the UN Sustainable Development Goals.

This volume brings together extended reviews and papers of new
scientific research on atmospheric nitrogen deposition impacts
globally. While there is a wealth of evidence on the magnitude,
components and effects of nitrogen disposition on floral
biodiversity in Europe and North America, there is an obvious lack
of information on impacts on above- and below-ground fauna, and all
impacts in other parts of the world, with no clear overview of how
the different strands of evidence fit together. This overall
synthesis is targeted at the international conventions, but is
equally readable for scientists, environmental managers,
conservation agencies and policy makers. 'This timely book
highlights the global nitrogen deposition problem. Major regions of
the world are exceeding sustainability thresholds for adverse
effects on ecosystem function and biodiversity. This highlights the
importance of ongoing work, including under the Convention on
Biological Diversity, in developing indicators and monitoring
nitrogen deposition effects to enable appropriate measures. This
book presents a milestone towards this global goal as the
international community works toward meeting the Aichi Biodiversity
Targets, especially Target 8: "By 2020, pollution, including from
excess nutrients, has been brought to levels that are not
detrimental to ecosystem function and biodiversity". Braulio
Ferreira de Souza Dias, Executive Secretary, Convention on
Biological Diversity "This key volume highlights the global
challenge to reduce atmospheric nitrogen pollution resulting from
energy production, transport and agricultural activities. It takes
forward the agenda recently launched in the UNEP commissioned
report 'Our Nutrient World". Dr. Anjan Datta, UNEP.
