The Dutch nitrogen cascade in the European perspective
Erisman, J.W. ; Domburg, P. ; Haan, B.J. de; Vries, W. de; Kros, J. ; Sanders, K. - \ 2005
Petten : ECN (ECN-C 05-007) - 109 p.
The Netherlands is "well known" for its nitrogen problems; it has one of the highest reactive nitrogen (Nr) emission densities in the world. It is a small country at the delta of several large European rivers. Ever since the industrial revolution, there has been a growing excess of nutrients and related emissions into the atmosphere (ammonia, nitrogen oxides and nitrous oxide) and into groundwater and surface water (nitrate), leading to a large range of cascading environmental impacts. Vehicular traffic, sewage and animal husbandry are the main sources of oxidized and reduced forms of Nr. This report provides an overview of the origin and fate of nitrogen in the Netherlands, the various reported impacts of nitrogen and the Dutch and European policies to reduce nitrogen emissions and related impacts. In addition, ways are presented to go forward to potentially solve the problems in a European perspective. Solutions include the improvement of nitrogen efficiencies in different systems, technological options and education.

SC-DLO ontwikkelt een kennissysteem (beslissingondersteunend systeem) voor bodeminventarisatie, waarmee statistische bodeminventarisatieplannen kunnen worden ontworpen. Een van de toepassingsmogelijkheden is het onderzoek naar bodemverontreiniging. Met het systeem kunnen inventarisatieplannen op maat ontworpen worden, afgestemd op de specifieke omstandigheden van individuele onderzoeksprojecten. Het systeem is hierdoor een goed alternatief voor een lange reeks van algemene en verbijzonderde protocollen.
A knowledge-based system for designing efficient soil survey schemes
Domburg, P. ; Gruijter, J.J. de - \ 1995
In: The third CODATA conference on geomathematics and geostatistics. Nancy (France), Ass. sci. Géol. Appl., 1995. Informatique géol. 32, Vol. 2 / Fabbri, A.G., Royer, J.J., - p. 505 - 514.
Decisions on land use or soil protection generally depend on soil survey information. There is a growing interest in information with quantified accuracy, which can be obtained by applying statistical sampling strategies. Prior to field work, a soil survey scheme must be designed, which is efficient with respect to accuracy of results and cost of operation. It was investigated how a knowledge-based system can support the design of such schemes. The structuring of the system domain and the tasks of the knowledge-based system are outlined. On this basis, it is indicated where the disciplines involved (soil science, statistics, computer science, and operations research) contribute to the development of the system.
Planning van een bodeminventarisatie - ondersteuning met een kennissysteem
Domburg, P. - \ 1995
In: Van bodemkaart tot informatiesysteem; verzamelen en gebruiken van informatie over de Nederlandse bodem / Buurman, P., Sevink, J., Wageningen : Wageningen Pers - p. 127 - 138.
Er is een toenemende vraag naar bodemkundige informatie waarvan de nauwkeurigheid gekwantificeerd is. Dit vraagt om een statistische aanpak bij het verzamelen en verwerken van bodemkundige gegevens. Deze bijdrage beschrijft een kennissysteem dat het ontwerpen van bodeminventarisatieplannen met een statistische aanpak ondersteunt. Het systeem volgt een gestructureerde aanpak bij het ontwerp, die garandeert dat alle belangrijke elementen aan bod komen. Een grote hoeveelheid kennis en ervaring, die opgeslagen wordt in het systeem, kan voor zeer uiteenlopende inventarisatieprojecten worden ingezet. De gebruiker speelt een belangrijke rol bij het aanleveren van gebieds- en situatiespecifieke informatie.

Soil survey information with quantified accuracy is relevant to decisions on land use and environmental problems. To obtain such information statistical strategies should be used for collecting and analysing data. A survey project based on a statistical sampling strategy requires a soil survey scheme specifying which sites are to be sampled, which data are to be recorded and how they are to be analysed statistically. The efficiency of such a scheme is determined by the accuracy of the survey results and the cost of operation. This accuracy and cost depend mainly on the method of determination and the sampling design in the scheme.

This study aimed at formulating the basic design considerations of a knowledge-based system (KBS) to assist in the design of soil survey schemes. This system should incorporate pedological and statistical knowledge. The domain of the system has provisionally been limited to surveys for which a design-based approach, i.e. the use of classical sampling theory, is appropriate.

Initially, the domain of the system has been structured in three layers: (i) an entity structure clarifying the position of the system in a soil survey project; (ii) a model describing the design process as a number of interrelated steps, and (iii) a conceptual framework defining the main concepts and their relations.

Further analysis made it possible to specify the tasks in which the KBS should assist: definition of the survey request, selection of prior information, design of outlinear schemes, evaluation and optimization of outlinear schemes, generation of a report, and evaluation a posteriori .

The system will primarily assist in the statistical decisions in the design process. Since there was no suitable classification of sampling designs available, a hierarchical framework of sampling designs has been constructed, in which sampling designs are grouped into types of designs, and types are grouped into classes of designs. Furthermore the main classes of sampling designs treated in the literature have been ordered in a taxonomy. Decision trees have been developed to guide the selection of an appropriate sampling approach (designbased versus model-based), and, in the case of a design-based approach, to guide the search for an appropriate class of sampling designs.

To ensure that the available means for a project, such as budget, personnel, and equipment, are used adequately schemes should be evaluated and optimized beforehand. Models related to the features of sampling designs have been developed for predicting the accuracy and cost of survey schemes, the so-called prior evaluation. Furthermore the use of dynamic programming is proposed to search for the optimal sampling design within an outlinear scheme. The procedure enables objective comparison of schemes taking into account differences in spatial variability or sampling cost among sub-regions.

Finally, basic design considerations are presented consisting of an initial requirements definition, a description of the intended use of the KBS, and a specification of the components for an actual KBS. Five components are distinguished: a database, a knowledge base, a model base, a problem-solving model, and a user interface. The system will assist in its own maintenance through continuous storage of knowledge from executed projects. This will facilitate the re-use of information. A KBS which is based on these basic design considerations will assist in controlling the quality of soil survey projects.
