English Abstract This report presents an analysis of the need and
possibilities for calculating agricultural emissions at RIVM. It describes
the tasks of the staff members and external institutions concerned with the
production of the Environmental Balance Report. All activities that are
required for calculating agricultural emissions are described in the form of
Data flow diagrams and the remaining problems are discussed. A global
description of data required follows. A series of alternatives for
implementation of calculating agricultural emissions are evaluated, which
results in the proposal of one solution. In this solution the data are
fully integrated in RIM+- the central database of the laboratory of waste
materials and Emissions. Maintenance screens for these data will have to be
developed. Conversion programs will produce input files for the existing
CLEAN calculating model and models in use by the Agricultural Economic
Research Institute LEI-DLO. The output of these models is imported into the
RIM+ database and can then be analyzed with the reports, graphs and
GIS-tools already available. The consequences of this solution for system
development is pursued further, resulting in a global description of
functions, data and the financial and personnel requirements for
implementation. A detailed design of the system will be presented in a
sequel report.
