“…More recently, several studies analyzed P flows on a long‐term basis at the national or global scale: Liu and colleagues () developed a single‐year SFA model for China, but linked it to selected critical P flows for the years 1980–1997. Ma and colleagues () provide an aggregated SFA of the Chinese P budget over the period 1984–2008. Chen and Graedel () conducted an SFA of global P flows for the period 1961–2013.…”

Summary Phosphorus (P) is a major agricultural nutrient and, in its mineable form, a potentially scarce resource. Countries with limited physical access to P should hence develop an effective national P governance. This requires analyses of trends and variations in P flows and stocks over time. Here, we present a long‐term P flow analysis for the Indian agri‐food sector from 1988 to 2011. Major P flows are imports of mineral P, fertilizer application, and uptake of animal fodder. The mineral P import dependency ratio is constant at around 93%. On average, 20% of P inputs to soils are lost through erosion. Key drivers of changes in P flows include population growth, dietary change, and agricultural intensification. To reduce its P fertilizer import dependence, India could, for example, substitute up to 19% of the presently applied mineral P if manure used as a household fuel were recycled, and up to 21% if P was fully recovered from wastewater and household waste. Comparing selected indicators for P use in agriculture with China and the European Union (EU) reveals that there are structural similarities, such as increasing fertilizer application rates and P accumulation in soils, with the first but large differences compared to the latter. The analyses highlight that in contrast to static indicators, the time‐continuous tracking of P flows provides substantial advantages, such as the identification of long‐term trends, drivers, and intervention options for sustainable P management, given that it allows for the interpretation of present indicators in the context of past trends and legacies.

Phosphorus (P) is an essential nutrient for all living organisms. P is mostly obtained from mined rock phosphate. However, existing rock phosphate reserves could be exhausted in the next 50-100 years. As Korea is totally dependent on imported rock phosphate, we should seek for solution to overcome the P depletion by efficient use and recycling. For this, this study suggested a P flow model to identify the location and flow route of P in urban area based on traditional material flow analysis. The type of P entering the urban areas are fertilizer, food and feed. Each type of P is used in agriculture, human consumption and animal husbandry. After going through each process, P is moved to waste management facilities within food waste, excreta and sewage. Some portion of P in waste are buried, incinerated and discharged, which can be reservoir of P in the future.Key words: Phosphorus, Material flow analysis, P depletion, Rock phosphate

“…In the case of China, PR resources will be consumed within the next 50e60 years. However, the development of the phosphorus resources industry results in significant issues, including waste from phosphate rock mining and processing, fluoride gas pollution, phosphor gypsum stack pollution, an excess of traditional primary phosphorus-chemical products, an excessive number of small-scale plants, and a low coupling structure of the industry (Ma et al, 2012(Ma et al, , 2013Villalba et al, 2008;Liu et al, 2008;Zhang and Ma, 2008;Pizzol et al, 2014). Efficient evaluation, recycling, and recovery of phosphorus constitute a global issue (Tran et al, 2014;Roya et al, 2014), and these activities have been conducted at every stage of the total life cycle of phosphorus metabolism (Corrales et al, 2014).…”
