Assessments of climate change impacts on species are needed for anticipating potential biodiversity losses. Climate change impacts on species are often simulated with climate envelope models, but most climate envelope models do not account for disper

Annual sulfate mass balances have been constructed for four low-lying peat polders in the Netherlands, to resolve the origin of high sulfate concentrations in surface water, which is considered a water quality problem, as indicated amongst others by

Water and nutrient budgets were con- structed for 13 low-lying peat polders in the Neth- erlands that varied in elevation relative to sea level (-0.2 to -2.4 m below sea level), land use (7-70% of the total polder area covered by agriculture; largely

A spatially explicit dynamic model was developed that combines water quantity and quality processes for an average Dutch peat polder. The model has been used to calculate the consequences of climate change for surface water level, groundwater level a

The European Union aims to increase the share of renewable energy in its total energy consumption to reduce greenhouse gas emissions and make the economy more CO2 neutral. This policy is further motivated by a desire to reduce dependency on fossil fu

This paper describes a methodology to explore the (future) spatial distribution of biofuel crops in Europe. Two main types of biofuel crops are distinguished: biofuel crops used for the production of biodiesel or bioethanol, and second-generation bio
