“…Others have suggested that such changes to P reserves may have presented an inflated picture of global reserves [Edixhoven et al, 2014]. Several recent special issues have delved into this issue more deeply than we can here, and we recommend the following recent special issues for the interested reader [Steiner and Geissler, 2018][Ulrich, 2016b] [Scholz and Hirth, 2015.…”

“…Whether P supplies dwindle or become more expensive in coming years, there is widespread agreement that future recycling of P or reducing use is necessary [Steiner and Geissler, 2018]. Agricultural practices could move from a push systemwhere P is applied liberally in concentrations higher than necessary, with possible detrimental human health effects [Calvo et al, 2014] to systems of precision agriculture where animals receive the precise amount of P necessary and soil is analysed to add only the correct amount of P. Even those that argue that there is no physical scarcity of phosphorus agree that there are legitimate reasons to ensure future generations' long-term supply [Brundtland 1987] [Steiner and Geissler, 2018].…”

“…Recent efforts have focused on developing a formal circular P economy, or complete regional recycling of all P inputs [Steiner and Geissler, 2018] and this can lead to surprising results such as Denmark imports three-fold more P from animal feed than mineral fertilizers [Klinglmair et al, 2015]. Many countries are starting to develop laws to mandate P recycling [European Commission., 2018] [Mehr et al, 2018.…”

“…The inefficient use of P today in industrial and agriculture systems results in losses of up to 95% along the supply chain [Scholz and Wellmer 2015]. As a result, recent work has focused on developing a circular P economy of efficient recycling [Steiner and Geissler, 2018] forwarding a 5R strategy: 1. Realign P inputs, 2.…”

“…From a systems perspective and as outlined in the previous sections, food security is not an independent, self-contained affair [28,81,82]. For example, it is compounded by the planet's increasing water and land scarcity, soil, land and biodiversity degradation and climate change leading to more frequent and severe weather events and their impact on agriculture.…”

Among the great challenges the world faces are how to ensure food security for its growing population—projected to rise to around 10 billion by 2050—so it can meet their nutritional needs for a healthy life. Current regulations and literature on food security mainly focus on food quantity (i.e., portion sizes), daily calorie intake and methods for increasing food production and too little on food and diet quality and the holistic effects of (mal)nutrition. From a systems perspective, in order to promote innovation policies for more sustainable food systems, food security cannot be viewed independently; rather, it is characterized by the interplay of an extensive network of economic, environmental and social dimensions that should all be taken into account in a comprehensive resilient and sustainable global food system. Here, we highlight one aspect of this vast network that we consider a particular challenge—yet also a great opportunity—for innovative policies geared toward more sustainable food systems: the interplay of hunger and obesity, including resulting policy strategies beyond potential efficiency improvements in farming practices. Future studies need to emphasize the importance of an in-depth understanding of the interdependencies within the global food system and its interrelatedness with societal and natural systems as part of coupled human-environment systems and in the face of continuing population growth and food demand globally. Recommended strategies for achieving sustainable food security systems include innovative educational approaches and stakeholder-driven innovation policies based on mutual learning processes between society, science, industry and policymakers, as well as fostering increased responsibility of all members of society along the agriculture and food value chain.

Phosphorus (P) can be recovered from wastewater and used as an alternative fertilizer, namely, struvite [MgNH4PO4·6(H2O)]. However, the soil mobility of wastewater‐derived P and other nutrients needs to be evaluated. The objective of this study was to compare the vertical distribution of water‐soluble (WS) soil P and other nutrients from a synthetic‐wastewater‐derived electrochemically precipitated struvite (ECST) to that from a chemically precipitated struvite (CPST), triple superphosphate (TSP), monoammonium phosphate (MAP), and a control in six soils from Arkansas (AR; loam [L] and silt loam [SiL]), Missouri (MO; SiL 1 and SiL 2), and Nebraska (NE; sandy loam [SL] and SiL). A column‐leaching experiment was conducted with the six soils and five fertilizer‐P treatments. Water‐soluble (WS) P from the two struvite materials generally did not differ (p > 0.05) and was similar to that of MAP in the depths of 0–3, 3–6, and 6–10 cm, but was greater than that of TSP in the top 6 cm in four of the six soils. WS P from CPST in the MO‐SiL 2 and NE‐SL soils (6.6 and 12.7 mg kg−1, respectively) was larger than that from ECST, MAP, and TSP. In the AR‐L and MO‐SiL 1 soils, TSP was the only fertilizer‐P source that had increased WS P concentrations in the top 6 cm relative to the other fertilizer‐P sources. Results showed that ECST‐derived, WS P had similar soil profile distributions in the top 10 cm, suggesting that ECST will be equally protective of environmental health and leachate quality across multiple soil textures as other common fertilizer‐P sources.
