Just Enough Nitrogen

Prof. Mark A. Sutton is an environmental physicist based at the UK Centre for Ecology & Hydrology, in Edinburgh. An expert on atmospheric ammonia, he leads international research activities on nitrogen at the science–policy interface. He is a former chair of the International Nitrogen Initiative (INI) and currently directs the UNEP/GEF International Nitrogen Management System (INMS) and the UKRI Global Challenges Research Fund’s South Asian Nitrogen Hub. Kate E. Mason is a professional archivist by training, based at the UK Centre for Ecology & Hydrology, Edinburgh where she works in an editorial capacity as part of the International Nitrogen Coordination Team. In addition to being Managing Editor of the present volume, she was Managing Co-Editor of the Springer book, Nitrogen Deposition, Critical Loads and Biodiversity.Dr. Albert Bleeker is an environmental scientist based at the Dutch National Institute of Public Health and the Environment (RIVM).  A former Director of Operations of the International Nitrogen Initiative and expert on nitrogen, atmospheric processes and critical loads, he now leads national scale analyses on nitrogen and environment.  Dr. W. Kevin Hicks is Senior Research Fellow at the Stockholm Environment Institute, based at the University of York.  His research interests cover air pollution impacts on terrestrial ecosystems from local to global scales, ecosystem services, air pollution issues in developing countries, and the transfer of scientific information to the policy process. He has helped organize various workshops, including a global meeting on Nitrogen Deposition, Critical Loads and Biodiversity which was the subject of a book published by Springer (2014). He is the currently Director of the European Centre of the International Nitrogen Initiative (INI).Dr. Cargele Masso is a Senior Researcher at the International Institute of Tropical Agriculture (IITA) based at its Yaoundé Research Station, Cameroon. An agronomist by training, his research focuses on nutrient management for improved livelihoods. He is a former Director of INI for Africa, and currently leads the East Africa Demonstration activity of the International Nitrogen Management System, focused on Lake Victoria Basin.Prof. N. Raghuram is the Chair of the International Nitrogen Initiative and a biotechnologist based at the Guru Gobind Singh Indraprastha University, New Delhi. His research focuses on nitrogen use efficiency under the NEWS India-UK and UKRI-GCRF-SANH. He co-led the Indian Nitrogen Assessment and facilitated the UN resolution on ‘Sustainable Nitrogen Management’. He is a Steering Committee member of the UNEP-GPNM, Trustee of the Sustainable India Trust and Editor in Chief of the journal, Physiology and Molecular Biology of Plants (Springer). Dr. Stefan Reis is Head of Atmospheric Chemistry and Effects (ACE) of the UKCentre for Ecology & Hydrology, based in Edinburgh. He is an expert on integrated modelling and assessment of impacts of air pollution and climate change on human health and ecosystems. His work focuses on development and application of conceptual models to link human and ecosystem health impact assessment.Prof. Mateete Bekunda is Chief Scientist of the Africa RISING Program’s East and Southern Africa Project funded by USAID:  ‘Sustainable Intensification of Maize-based Farming Systems of East and Southern Africa’, hosted by the International Institute of Tropical Agriculture, based at Arusha, Tanzania.  He is an expert in soil fertility, former Professor of Soil Science and Dean of the Faculty of Agriculture at Makerere University, and was previously INI Regional Director for Africa.
