“…). A key challenge of P management is how to maximize the benefits of P for agriculture while reducing the negative impacts of P for society, which is particularly important given the finite nature of phosphate rock from which mineral P fertilizers are derived (Cordell and White , Nesme and Withers ).…”

The essential role of phosphorus (P) for agriculture and its impact on water quality has received decades of research attention. However, the benefits of sustainable P use and management for society due to its downstream impacts on multiple ecosystem services are rarely acknowledged. We propose a conceptual framework—the “phosphorus‐ecosystem services cascade” (PESC)—to integrate the key ecosystem processes and functions that moderate the relationship between P released to the environment from human actions and ecosystem services at distinct spatial and temporal scales. Indirect pathways in the cascade via soil and aquatic processes link anthropogenic P to biodiversity and multiple services, including recreation, drinking water provision, and fisheries. As anthropogenic P cascades through catchments, it often shifts from a subsidy to a stressor of ecosystem services. Phosphorus stewardship can have emergent ecosystem service co‐benefits due to synergies with other societal or management goals (e.g., recycling of livestock manures and organic wastes could impact soil carbon storage). Applying the PESC framework, we identify key research priorities to align P stewardship with the management of multiple ecosystem services, such as incorporating additional services into agri‐environmental P indices, assessing how widespread recycling of organic P sources could differentially impact agricultural yields and water quality, and accounting for shifting baselines in P stewardship due to climate change. Ultimately, P impacts depend on site‐specific agricultural and biogeophysical contexts, so greater precision in targeting stewardship strategies to specific locations would help to optimize for ecosystem services and to more effectively internalize the downstream costs of farm nutrient management.

“…Entre autres conséquences, on observe un pilotage de plus en plus fort des filières agroalimentaires par l'aval (opérateurs de la transformation et de la distribution), un découplage entre systèmes de production et usage des ressources locales, les systèmes étant de plus en plus artificialisés et basés sur le recours à des intrants. Ces transformations affectent les écosystèmes locaux, notamment par un accroissement des flux de matières et d'énergie et l'absence de bouclage des cycles des matières (Nesme et Withers, 2016). Elles induisent d'importantes dépenses énergétiques, et affectent la vie économique et sociale des territoires (Buclet, 2011).…”

Résumé -Le processus de globalisation s'accompagne d'une importante restructuration des filières agricoles, se traduisant par une déconnexion de plus en plus forte entre opérateurs des filières et ceux des territoires, et entre lieux de production et usages des ressources locales. Les opérateurs des filières utilisent des ressources des territoires, mais n'y opèrent souvent qu'une partie de leur activité, et ne se soucient pas toujours de leur impact local, environnemental comme socioéconomique. Il y a un réel enjeu socioécologique à reconnecter les dynamiques des filières agricoles à celles des écosystèmes, à l'échelle des territoires, là où les activités de production prennent place. Pour cela, il est nécessaire de comprendre au préalable les formes d'interaction entre filières et territoires, pour pouvoir ensuite agir dans une perspective de développement durable. Nous avons élaboré un cadre d'analyse des formes d'interaction entre filières et territoires, interrogeant les formes d'ancrage des filières agricoles aux territoires, les formes de dépendance des territoires, pour leurs filières, vis-à-vis de ressources et opérateurs exogènes, ou d'autres territoires, enfin les formes d'empreinte des filières agricoles pour les territoires ou de la production agricole du territoire pour le reste du monde. Nous proposons ici une revue ciblée de la littérature sur les différentes méthodes existantes permettant de traiter ces différentes dimensions et leurs déclinaisons selon l'enjeu considéré : environnemental ou socioéconomique. Les approches biophysiques d'un côté et socioéconomiques de l'autre restent largement dissociées, ce qui nous amène à discuter de l'opérationnalité de ce tour d'horizon pour la communauté scientifique. Nous formulons également quelques recommandations, notamment pour éviter l'écueil du « localisme ». what methods? Globalization comes along with an important restructuring of the agricultural value chains, resulting in an ever more important disconnection between operators of the supply chains and those of the territories, and between production sites and use of local resources. Operators of supply chains, which make use of local resources, often operate only a small part of their activity locally and do not always care about their environmental or socioeconomic impacts. There is a major challenge to reconnect supply chains' and ecosystems' dynamics at territory level. First, it requires understanding the types of interactions between supply chains and territories, to be able to design pathways for their sustainable co-evolution. We developed an analytical framework presenting forms of interactions between supply chains and territories, questioning the types of: anchoring of the agricultural activities in territories; dependence of territories to exogenous resources, operators or territories; footprints of the agricultural activities on local territory or on the rest of the world. We propose here a review of existing methods handling these different dimensions and their versions according to t...

“…However, agricultural infrastructure would need to change dramatically, which is unlikely in the short term and with current voluntary approaches. Further, shifts in agricultural production away from some of the most productive soils in the United States (the Upper Mississippi River basin and Great Lakes) to protect water quality are unrealistic, given that large-scale production in these areas provides economies of scale needed to maximize efficient food and biofuel production, as well as resource use and management (Hanserud et al, 2016;Nesme and Withers, 2016). The reality is that fragmenting and moving grain production to less productive soils will likely reduce yields and could even undermine national food security.…”

Core Ideas Meta‐analysis of “big data” can identify P disconnects in P cycles, stocks and flows. Understanding of farming realities is needed to identify root causes of change. Access to “big data” without grounding in reality can lead to misleading conclusions. Researchers must ensure production and conservation tactics consider farming realities. With more sophisticated data compilation and analytical capabilities, the evolution of “big data” analysis has occurred rapidly. We examine the meta‐analysis of “big data” representing phosphorus (P) flows and stocks in global agriculture and address the need to consider local nuances of farm operations to avoid erroneous or misleading recommendations. Of concern is the disconnect between macro‐needs for better P resource management at regional and national scales versus local realities of P management at farm scales. Both agricultural and environmental researchers should focus on providing solutions to disconnects identified by meta‐analyses and ensure that production and conservation strategies consider farming realities.
