  1. Global nitrogen and phosphate in urban wastewater for the period 1970 to 2050

    This paper constitutes the first spatially explicit, global assessment of sewage N and P emissions to surface water for the period 1970 to 2000, and the first projection of such N and P emissions...

  2. Global N removal by freshwater aquatic systems using a spatially distributed, within-basin approach

    In this article the role of aquatic systems in the global N cycle is explored using a spatially distributed, within-basin, aquatic nitrogen (N) removal model, implemented within the Framework for...

  3. What is reactive nitrogen (Nr) and how does IMAGE calculate current and future Nr emissions?

    Cycles, 16(4): 1058 doi: 10.1029/2001GB001811. Bouwman A.F., Boumans L.J.M. and Batjes N.H. ... doi:10.1029/2000GB001389. Bouwman A.F., Boumans L.J.M. and Batjes N.H. (2002c) Modeling global annual N2O and NO emissions from fertilized fields. Global Biogeochemical Cycles, 16(4): 1080 doi:10.1029/2001GB ...
  4. Impacts of future land cover changes on atmospheric CO2 en climate

    Climate-carbon cycle model CLIMBER2-LPJ is run with consistent fields of future fossil fuel CO 2 emissions and geographically explicit land cover changes for four Special Report on Emissions...

  5. CO2 and albedo climate impacts of extratropical carbon and biomass plantations

    We explored the climate impacts for two land-use change scenarios, aimed at mitigating the buildup of greenhouse gases in the atmosphere. Using the integrated assessment model IMAGE 2.2, we found...

  6. River nitrogen export to the worlds oceans

    This paper discusses historical and future anthropogenic disturbance of river nutrient loads and export to coastal marine systems, which is a major global problem affecting water quality and...

  7. Sources and delivery of carbon, nitrogen, and phosphorus to the coastal zone: an overview of Global Nutrient Export from Watersheds (NEWS) models and their application

    An overview of the first spatially explicit, multielement (N, P, and C), multiform (dissolved inorganic: DIN, DIP; dissolved organic: DOC, DON, DOP; and particulate: POC, PN, PP) predictive model...

  8. A comparison of global spatial distributions of nitrogen inputs for nonpoint sources and effects on river nitrogen export

    We compared four global data sets for the year 1995 for nonpoint N sources with 0.5° by 0.5° spatial resolution. Data were developed to drive models for assessing the river export of nitrogen (N)...

  9. Dissolved inorganic phosphorus export to the coastal zone: results from a spatially explicit, global model

    Here we describe, test, and apply a spatially explicit, global model of river-borne dissolved inorganic phosphorus (DIP) export called NEWS-DIP. Among the innovations in NEWS-DIP are increased...
