This thesis addresses the effects of historical and projected land use changes on precipitation in the Netherlands. The thesis first deals with the observed increase in precipitation in the last century and indicates that this is most likely related to an increase in sea surface temperature. It is also found that along the Dutch West coast (the Randstad) precipitation is enhanced downwind of urban areas. Next, the atmospheric Weather Research and Forecasting (WRF) model is used to investigate the sensitivity of precipitation to the land surface in the Netherlands in spring and summer. Land use conversions from historic to present, and present to future, led to a small decrease in precipitation. In all, precipitation will likely continue to increase over the coming decades, more so as a result of climate change than from land conversion. Nevertheless, in the Netherlands the influence of land surface changes is not negligible and counters the effect of climate change on precipitation.
