Sustainable Phosphorus

Compared with other nutrients, the biogeochemical cycle of phosphorus (P), together with that of nitrogen, is one of the most dramatically altered by human activities, and especially by the rapidly increasing use of P fertilizers over recent decades. Global models estimate that the flux of P from the land to rivers and oceans has more than doubled since the start of the industrial era, with negative impacts on aquatic ecosystems through their eutrophication. These now endemic environmental impacts are the obvious warning signs of the uncontrolled management of P driven by the need to grow more food.. Phosphorus is a key factor controlling the net primary productivity and species assemblages in many natural terrestrial ecosystems, and hence in many agroecosystems as well. Global models predict that climate change and nitrogen deposition will disrupt both natural and managed ecosystems, with potential negative feedbacks from the biogeochemical cycles of the most limiting nutrients such as P and micronutrients. Understanding such feedback loops of P availability in soils and sediments on the biogeochemical cycles of carbon and nitrogen, including stoichiometric constraints, is vital for future food security, ecosystem services, environmental protection and biodiversity. In addition, phosphate rock is a finite resource whose future availability is becoming increasingly bleak. As a consequence, the increasing cost of P fertilizers is a major concern for achieving the agricultural intensification required to feed an ever-growing world population, notwithstanding the geopolitical issues related with the uneven distribution of phosphate rock deposits. There is thus a pressing need to adequately face these various P-related issues with a holistic approach, in order to more efficiently use this precious resource. An effective strategy must include minimizing the P losses all along the production/consumption chain, more effective recycling and recovery of P in our wastes and redesigning our agricultural farming systems to make them more efficient and sustainable.

SPS 2014 is the fourth of a young and successful series of Sustainable Phosphorus Summits that was launched in Linköping (Sweden) in 2010, as part of the GPRI, Global Phosphorus Research Initiative, and follows in the footsteps of the last SPS in Sydney (Australia) in 2012, which produced the Blueprint for Global Phosphorus Security. Coming to the Mediterranean basin at Montpellier (France) will facilitate the participation and necessary interaction of African scientists, and other developing countries, where P sustainability is a major concern.

The primary aim of this multidisciplinary event is to define the global agenda for research priorities, and to integrate P-related issues across scales, geographical regions and scientific domains. To do so, it will bring together scientists and stakeholders worldwide, including developing and emerging countries, to foster exchange of views across disciplines and societal sectors. In order to better improve P use efficiency along the entire food chain, raising public awareness is a major issue, as well as re-thinking education and learning on this topic. Participatory research and co-learning will thus be central to this event. SPS 2014 will take place from 1st to 3rd September 2014, i.e. immediately after the 5th International Symposium on Phosphorus in Soils and Plants to be held also in Montpellier from 26th to 29th August 2014, that will focus on the dynamics of P in the soil/plant continuum.

Over the last four years, Nutrient Cycling in Agroecosystems has published about 70 papers dealing with P. This virtual issue is a selection of 22 papers published between 2011 and 2014, and 3 highly-cited, older papers, covering most of the main scientific themes to be addressed at SPS 2014. The papers have been classified according to the SPS sessions, i.e.(i) Phosphorus in our world (i.e. P cycling at global level and large scales), (ii) Phosphorus in our resources and environment, (iii) Phosphorus in our fields and food, (iv) Phosphorus in our wastes. After SPS 2014, Nutrient Cycling in Agroecosystems will prepare a special issue on P resource management based on a selection of the best communications from the Summit.

We wish everyone an enjoyable and productive summit and look forward to receiving manuscripts to be part of the forthcoming SPS 2014 - Sustainable Phosphorus Summit special issue of Nutrient Cycling in Agroecosystems.
