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 ruminant meat and milk production has been achieved by increasing the production in...
Environmental fate modelling is now actively used for the registration of plant protection products (PPPs). Yet, to be efficient in a harmonized registration process, the quality of PEC modelling needs to be assured.
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 in pesticide properties. In a GIS approach the variability is explicitly...
As part of the new governmental program on pesticides the Dutch ministry of Agriculture, Nature Management & Fisheries and the ministry of Housing, Spatial Planning & the Environment have jointly commissioned the development of the Dutch National Environmental Indicator for...
In this paper, information from 846 N2O emission measurements in agricultural fields and 99 measurements for NO emissions was used to describe the influence of various factors regulating emissions from mineral soils in models for calculating global N2O and NO emissions. Only...
Food security may be threatened by loss of soil productivity as a result of human-induced land degradation. Water erosion is the most important cause of land degradation, and its effects are irreversible.
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.
CD-rom publication (MNP publication 500110001, reprint of RIVM publication 481508018). A comprehensive analysis of emissions, climate change and impacts in the 21st century. Main disc.
The use of pesticides in agriculture presents risks to the environment, which are evaluated more and more by using computation models. The new PEARL model simulates the behaviour of pesticides in soil-plant systems and their emissions to the environment.
Global Change Scenarios of the 21st Century informs readers of conceivable environmental changes in the next hundred years. Integrated scenarios are used to communicate large amounts of information about different aspects of the global environmental system, together with...
