A three days conference in Wageningen

Spatial statistics for production ecology

GIS, Modelling and Remote Sensing

19 - 21 April 1999

Production ecology (PE) aims at competitive production in an environmentally
friendly way. Modern approaches like precision agriculture and integrated
pest and disease management rely on the use of models. Basic input for these
models is increasingly collected by remote sensing, and also data stored in
geographical information systems (GIS) are used. GIS is indispensable to
combine sources of data and to visualize important spatial information. In
all, modern production ecology leads to decisions that are better supported
by the most recent agricultural knowledge, and hence to more sustainable use
of land.

Spatial statistics is important in aspects of production ecology. Spatial
statistics quantifies uncertainty and supports problem solving in issues of
scale and spatial modeling. Examples include interpolation of agricultural
models to field or regional scales, quantification of uncertainty in GIS,
upscaling, and use of remote sensing images for decision support.

In association with the International Statistical Institute and sponsored by
the Netherlands Academy of Sciences we organize the international conference
of Spatial Statistics for Production Ecology. The aim of this conference is
to present up-to-date develop-ments in spatial statistics for PE, to present
on-going research and to discuss important problems to be addressed in the
near future. Three themes have been distinguished: GIS, Modelling and Remote
Sensing. Distinguished national and international speakers have been invited
to present an overview of state-of-the-art, and researchers will present
front-line research in any of the three themes.

The conference takes place in the Wageningen University and Research Centre,
in the new building of the Winand Staring Centre, rooms 1 and 2,
Droevendaalsesteeg 3, 6708 PB Wageningen. This building has excellent
conference facilities with all modern equipments for presentations. It now
also hosts the Wageningen UR Geoinformation Centre that is responsible for
teaching programmes of geoinformation, takes part in research projects and is
a service centre for geodata . It is situated in the northern part of
Wageningen and can easily be reached by public transport and by car.


Every oral and poster presentation is accompanied by a written scientific
paper to be sent to the conference secretariat by 1 April 1999 at the latest.
Pre-proceedings are compiled in three volumes, one for each theme, and will
be delivered at the start of the conference. The papers will be reviewed and
accepted papers will be published in a special issue of Environmental and
Ecological Statistics, Editor-in-Chief, GP Patil.


The fee for three-days attendance of the congress is Dfl. 250,-. One-day
registration is possible at the cost of Dfl. 95,-. Fee includes access to the
full congress program, a copy of the pre-proceedings, lunches, coffee and
tea. and access to the conference dinner at Tuesday night for three-day
attendants. One-day attendants can join the dinner for Dfl. 60,-. Registered
research students from the CT de Wit Research School of Production Ecology
will not pay fees but will earn credit points in stead.

The Program

The scientific program consists of various types of contributions.

1. Invited papers to give an overview of the state of the art or of modern
developments in any of the three themes of the conference. Presentations will
last 40 minutes, and will be followed by a brief 5 min. discussion for

2. Contributed papers to present front-line research in any of the three
themes of the conference. Presentations will last 20 minutes and will be
followed by an extensive 20 minute discussion. In this discussion interaction
among the audience and speakers will be encouraged.

3. Posters to present the latest developments. These posters will be on
display all during the conference, and there will be ample time to discuss
these with the presenting scientists.

4. General discussions concentrating on all aspects relating to the themes of
the day.

5. GIS demonstrations to show the latest developments in geographical
information systems

In addition there are several social activities, like a welcome reception,
the conference diner on Tuesday evening, and extended tea and coffee breaks
and end-of-the-day receptions to allow informal contacts.
