Postgraduate Course

Crop Modelling and Climate Change:
Training the Next Generation of Crop Modelers for Crop Model Development and Improvement

10 - 15 March 2024

Parkhotel 'de Bosrand', Ede, the Netherlands

Organised by  The Graduate School PE&RC & the University of Florida  

Scope

In this age of artificial intelligence models, mechanistic crop growth models are more important than ever. Plant and crop growth simulation models are now a basic tool for many researchers. Yet, there is a shortage of model developers, scientists with knowledge about underlying mechanistic processes and skills to transform this knowledge into scientific equations and sound models. Such modelling skills are highly demanded in the labour market. Many of the more commonly used mechanistic crop models have a challenge to cope with climate change factors such as increased CO2, droughts and floods, temperature, variability, extreme events, and especially the interaction among these factors. There is, therefore, an urgent need to train the next generation of scientists on the further development of dynamic crop simulation models. This post-graduate course focusses on just that. Crop models refer to models that deal with crops, contrasting with e.g. virtual plant models that are focussing on interactions between individual plants. Together with international senior scientists in crop modelling, participants will take up the challenge to acquaint themselves with the process of crop modelling and to develop new insights to strengthen current crop models. We start with theory and concepts and state-of-the-art lectures on the key processes of crop growth to be modelled (and how) and we will also address the importance of both model calibration and evaluation and associated data requirements.

Participants will learn about the detailed processes that play a role in crop development and growth and the interaction of crops with soil water and nutrients and will evaluate the impact of processes that are/are not included in the selected models in relation to climate change. Limitations of current dynamic crop growth models and challenges that remain will be addressed. The main focus of this course will on the use and accuracy of sole crop simulation models, although aspects of intercropping will be mentioned. Availability of proper data for model development, calibration and evaluation is key in making progress. This topic will receive attention in the course. Participants will be challenged to analyse how existing models can be adapted, calibrated, and evaluated in a modern dynamic simulation environment.

Course set-up

1. Key-note / Introduction Lecture
The course starts off Sunday afternoon with an introduction to the course, followed by a key-note address in which the invited speaker will give his/her perspective on how models should be adapted to cope with climate change.

2. Poster Carousel
After the Sunday dinner there will be a poster carousel in which participants introduce themselves via a poster. Each round lasts 15 minutes (5 minutes introduction and 10 minutes questions and discussion). Prior to the course, participants must submit a poster in PDF, which will be printed by the course office (A1-size). The poster must contain your name and affiliation, title and short description of your research project with one highlight on crop modelling and the reason why you want to participate in this course. Posters will remain in the lecture room throughout the course.

3. Lectures and Discussion
Each day will start off with a set of lectures of 30-45 minutes. Each lecture is followed by a discussion of 15 minutes in which participants challenge the speaker on the presentation and a paper that the speaker provided prior to the course.

Lectures

4. Tutorials
Besides lectures there will also be a set of tutorials in which modelling procedures are explained and demonstrated.

5. Group Work
Afternoons are primarily spent on group work. Each group (5 participants) will be working on making models more robust to climate change. Focus is on water and/or temperature. We will be working with WOFOST (3-4 groups) and DSSAT (2-3 groups). Topics include modelling responses to climate variability and climate change where the following will be discussed:

  • Phenology and development
  • Photosynthesis and respiration
  • Biomass partitioning
  • Transpiration and water uptake
  • Soil water dynamics
  • Root growth
  • Nutrient uptake
  • Soil nutrient and organic matter dynamics
  • Minimum data for crop modelling
  • Model calibration and evaluation

Output of the group work will be presented on Friday morning in 15-minute presentations per group followed by 15 minutes discussion.

To participate, candidates must have a solid basis (that can be demonstrated) in:
  1. Systems analysis and modelling;
  2. Experience in using crop models;
  3. Experience in scripting, coding, and programming.

    Participants must have a letter of recommendation from their supervisor / superior that they have the skills to actively participate in the course.
    Please note that you have to bring your own laptop.
