dc.description.abstractEnPhosphorus (P) plays a key role in many agroecosystems both as a limiting nutrient of crop production and as a factor controlling eutrophication in freshwater ecosystems. The context of increasing global rock phosphate scarcity requires more efficient farming systems that both promote P resource recycling and limit P losses to aquatic systems. This keynote will provide a global picture of P management in agroecosystems: we will point out the current imbalanced distribution of P application to soils at global scale and will stress the key role of past accumulated P in many agricultural soils in allowing for crop productivity for future decades. We will also address issues related to P resource recycling within and to agroecosystems: using an industrial ecology perspective, we will examine how crop and livestock integration, agricultural specialisation, and trade act as drivers of P flows at different scales ranging from small territories to global scales. Finally, we will discuss to what extent P recycling from urban sources (e.g., as compost or sludge) can contribute to meeting P demand in agroecosystems.
