Peatlands are found on all continents, however, uncertainties regarding their size and exact locations are very high. Horticulture is the main user of peat in the Netherlands. Compared to other…
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 for…
Bottom-up uncertainty estimate of global ammonia emissions from global agricultural production systems
n this paper we describe differences in the uncertainty of NH 3 emissions from agriculture and the major factors determining the uncertainty between countries and world regions, i.e. the USA, the…
A framework to identify appropriate spatial and temporal scales for modeling N flows from watersheds
Many different large-scalewatershed nitrogen (N) flowmodels exist, which describe processes related to the horizontal movement of N through large drainage networks of river basins. Equations of such…
Denitritication across landscapes and waterscapes: a synthesis
Both newly fixed N and recycled N (e.g., manure) are processed by terrestrial ecosystems. A substantial portion of this recycled N is subsequently transferred to groundwater, wetlands, lakes, rivers…
Comparison of GeoPEARL with the single scenario approach in pesticide registration
Several countries use one or a few scenarios to evaluate the leaching of pesticides. This, however, can be too strict for some substances while being too lenient for others, because of the wide ranges…
Modelling the impact of climate change on the Wadden Sea ecosystem
In the framework of the Dutch National Research Programme on Global Air Pollution and Climate Change, ecological responses of the Wadden Sea ecosystem to changing climate conditions have been studied.
Nitrogen pollution on the local and regional scale: the present state of knowledge and research needs
Concerns the results of a feasibility study on the realisation of a nitrogen research programme for the local scale. This study, initiated by the Ministries of Housing, Physical Planning and…
