SWAP 50^th birthday in 2024

The SWAP (Soil-Water-Atmosphere-Plant) model and its predecessors such as SWATRE and SWACROP are celebrating their 50^th anniversary in 2024. To celebrate this milestone a special paper was published in which the latest developments were discussed, including:

• Crop growth i.r.t. soil, climate and water management including root development
• Soil hydraulic properties
• Drought stress: empirical and process-based concepts
• Oxygen stress
• Case studies
• Promising developments in the near future

Secondly, a symposium was organized to celebrate this birthday (Wageningen, the Netherlands; November 22, 2024). In the morning session contributions focussed on scientific developments in SWAP (all in English). In the afternoon session examples of the use of SWAP in several projects were discussed (all in Dutch). You can find the programme here. The contributions of this symposium are available below:
