Een nationaal en lokaal beleid gericht op vermindering van de grootstedelijke problemen blijft zinvol; ook na 2009, wanneer het huidige grotestedenbeleid ten einde loopt. Wel is het beter de…
Wat levert een fietsvriendelijke afstelling van verkeerslichten op?
De fiets is het duurzame transportmiddel bij uitstek: fietsen is goedkoop, op de korte afstand in steden meestal sneller dan andere vervoermiddelen, fietsen levert nauwelijks luchtverontreiniging of…
De uitstoot aan luchtverontreiniging in Europa is in de afgelopen 15 jaar aanzienlijk verminderd. Het beleid van de Europese Unie heeft vooral de vervuiling door de elektriciteitsproductie, de…
Permissible manure and fertilizer use in dairy farming systems on sandy soils in The Netherlands to comply with the Nitrates Directive target
Based on experimental data, this study explores the limits on the use of cattle slurry and mineral fertilizer in grass and silage maize. Cut grasslands can utilize cattle slurry up to 340 kg nitrogen…
Biodiversity and socioeconomic impacts of selected agro-commodity production systems
This article dicusses an assessesment of the socioeconomic and biodiversity impacts associated with the production of selected agro-commodities in their production countries and areas.
Permissible manure and fertilizer use in dairy farming systems on sandy soils in The Netherlands to comply with the Nitrates Directive target
From the point of view of N leaching and P accumulation, manure rates should be determined by (i) the harvest regime of the grass, (ii) the proportions of grass and maize in the farm area and the way…
Effects of changes in CO2, climate, and land use on the carbon balance of the land biosphere during the 21st century
Our results imply that the potential positive feedback of the terrestrial biosphere on anthropogenic climate change will be strongly affected by land-use change. Spatiotemporally explicit projections…
Climate change and the EU water framework directive: how to deal with indirect effects of changes in hydrology on water quality and ecology?
It is thought that the complexity of lake ecosystems makes this effect inherently unpredictable. However, models that deal with this complexity are available and well calibrated and tested.
Climate simulation of the twenty-first century with interactive land-use changes
The dynamics of natural vegetation is more closely linked to climate but the time-scale of changes is of the order of a century. Thus, the coupling between natural vegetation and climate could…
Exploring the impact on cost and electricity production of high penetration levels of intermittent electricity in OECD Europe and the USA, results for wind energy
With increasing penetration levels the cost reduction of wind electricity caused by upscaling and technological learning is counteracted by the cost increase due to the need for additional back-up…
