The series of papers in this issue AMBIO represent technical presentations made at the 7th International Phosphorus Workshop (IPW7), held September, 2013 Uppsala, Sweden. At that meeting, 150 delegates were involved round table discussions on major, predetermined themes facing management agricultural phosphorus (P) for optimum production goals with minimal water quality impairment. six (1) P a changing world; (2) transport pathways from soil to water; (3) monitoring, modeling, and...
ABSTRACT Construction of wetlands is a possible supplement to best management practices (BMP) at the field level mitigate phosphorus (P) pollution from agricultural areas. In this paper, annual results 17 intensively studied in cold temperate or boreal climatic zone are reported and analyzed. Surface areas varied 0.007 8.7% catchment area. The average total (TP) retention 1 88%, dissolved reactive (DRP) −19 89%. Retention substantially site site, indicating existence site‐specific factors...
One measure used in Sweden to mitigate eutrophication of waters is the construction small wetlands (free water surface wetland for phosphorus retention [P wetlands]) trap particulate (PP) transported ditches and streams. This study evaluated P dynamics a newly constructed serving 26-ha agricultural catchment with clay soil. Flow-proportional composite samples were collected at inlet outlet over 2 yr (2010–2011) analyzed total (TP), dissolved (DP), (PP), suspended solids (TSS). Both winters...
Abstract Increased recycling of nutrient-rich organic waste to meet crop nutrient needs is an essential component a more sustainable food system. However, agricultural specialization continues pose significant challenge balancing and the supply from animal manure human excreta locally. For Sweden, this study found that all (in 2007) could up 75% nitrogen 81% phosphorus needs, but would exceed potassium by 67%. Recycling within municipalities 63% P large regional differences imbalances need...
With growing urbanization cities become hotspots for nutrients. Food items are imported and food residues, including excreta not-eaten food, often exported to landfill sites water bodies. However, urban sanitation systems can be designed achieve a high degree of nutrient recovery security while counteracting current resources depletion, environmental degradation wasteful energy use. This article illustrates how an extended solid waste hierarchy also human wastewater guide actions save...
Combating eutrophication requires changes in land and water management agricultural catchments implementation of mitigation measures to reduce phosphorus (P), nitrogen (N) suspended sediment (SS) losses. To date, such have been built many catchments, but there is a lack studies evaluating their effectiveness. Here we evaluated the effectiveness clay soil‐dominated headwater catchment by combining evaluation long‐term high‐frequency data with punctual measurements upstream downstream three...
ABSTRACT Improved understanding of the importance different surfaces in supporting attached nitrifying and denitrifying bacteria is essential if we are to optimize N removal capacity treatment wetlands. The aim this study was therefore examine a constructed wetland assess relative these for overall wetland. Intact sediment cores, old pine spruce twigs, shoots Eurasian watermilfoil ( Myriophyllum spicatum L.), filamentous macro‐algae were collected July November 1999 two basins system. One...
In South Sweden, free water surface wetlands have been built to treat wastewater from municipal treatment plants. Commonly, nitrogen removal has the prime aim, though a significant of tot-P and BOD7 observed. this study, performance data for 3-8 years four large (20-28 ha) FWS evaluated. Two them receive effluent WWTP with only mechanical chemical treatment. At other two, also treated biologically resulting in lower concentrations NH4+-N. The performed satisfactorily removed 0.7-1.5 ton N...
Constructed wetlands can be used to decrease the high ammonium concentrations in landfill leachates. We investigated nitrification/denitrification activity and corresponding bacterial communities leachate that was treated a compact constructed wetland, Tveta Recycling Facility, Sweden. Samples were collected at three depths filter bed sediment from connected open pond July, September November 2004. Potential ammonia oxidation measured by short-term incubation method potential denitrification...
To meet the Millennium Development Goal for sanitation around 440,000 people will have to be provided with adequate every day during 2001–2015, and corresponding figure WHO/UNICEF target of “sanitation all” by 2025 is 480,000 per 2001–2025. The provision services such huge numbers necessitates action on an unprecedented scale. This made even more difficult general lack knowledge part professionals intended beneficiaries about which arrangement most appropriate under circumstances. A...
As global consumption expands, the world is increasingly facing threats to resource availability and food security. To meet future demands, agricultural efficiency needs be optimized for both water nutrients. Policy makers should start radically rethink nutrient management across entire chain. Closing loop by recycling nutrients in waste excreta an important way of limiting use mineral nutrients, as well improving national This article presents a framework sustainable discusses...
