Question
What is the science view approach in Wageningen?

System thinking in Wageningen
Systems thinking is the process of understanding how things influence one another within a whole
![Page 6: 1 / x Complex Adaptive systems GRS-21306 Introduction Arnold Bregt](https://reader030.vdocument.in/reader030/viewer/2022032523/56649d8c5503460f94a742b6/html5/thumbnails/6.jpg)
Comparison approachesUse Newtonian techniques when the problem is:
Quiet familiar
Well defined
Closed to outside influence
Linear, the inputs and outputs are clearly distinguishable
Use complex techniques when the problem is:
New and unique
Fuzzy or unknown
Open to outside influences
Nonlinear, the inputs and outputs are not clearly
distinguishable

Example organization
In organizations, systems consist of people, structures, and processes that work together to make an organization healthy or unhealthy

Example Nature
In nature, systems thinking examples include ecosystems in which various elements such as air, water, movement, plants, and animals work together to survive or perish.

Question
Can you give examples of pro’s and con’s of both approaches?

Complex Adaptive System
Complex Adaptive System is a dynamic network ofmany agents (which may represent cells, species, individuals, firms, nations) acting in parallel and constantly, and reacting to what the other agents are doing (Waldrop, 1992).

CAS application in Wageningen
CAS is the concept/ theory
ABM (Agent Based Modelling) is the implementation)

Hypothesis:
CAS characteristics and behaviors can also be found in SDIs.
