Postponing emission reductions from 2020 to 2030 increases climate risks and long-term costs
Substantially postponing the emission reductions, compared to the ranges indicated in IPCC’s recent assessment for 2020 as required for meeting the longterm 2°C target, increases the risk of exceeding…
Consequences of the cultivation of energy crops for the global nitrogen cycle
We quantified the impact of the production of energy crops on the global N cycle for the recently published OECD “Global cooperation for environmental policy” (GC) scenario. We project that large…
Human alteration of the global nitrogen and phosphorus soil balances for the period 1970–2050
The Millennium Ecosystem Assessment (MEA) scenarios allow for describing contrasting future developments in agricultural nutrient use under changing climate for the next five decades. Massive…
Traffic emissions of elemental carbon (EC) and organic carbon (OC) and their contribution to PM2.5 and PM10 urban background concentrations
The contribution of carbon to particulate matter is larger in urban areas than outside those areas. The increment in urban EC and OC concentrations was found mainly to be caused by traffic emissions…
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…
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…
Exploring changes in world ruminant production systems
In the past 30 years world production of ruminant meat and milk has increased by about 40%, while the global area of grassland has increased by only 4%. This is because most of the increase in…
A global high-resolution emission inventory for ammonia
A global emissions inventory for ammonia (NH3) has been compiled for the main known sources on a 1°×1° grid, suitable for input to global atmospheric models.
Transport scenarios for the Netherlands for 2030. A description of the scenarios for the OECD project 'Environmental Sustainable Transport'
The Environmental Sustainable Transport (EST) project contains a business-as-usual scenario and three EST scenarios: one 'high-technology' scenario containing only technological changes, one 'capacity…
