SExI-FS

The SExI-FS, developed by ICRAF, has become the go-to tool for those interested in optimizing agroforestry management practices. Focusing on tree-tree interactions within mixed multi-species agroforests, the program's capabilities align closely with individual tree care and regular tending practices that many farmers utilize. Users can download the program for free, making it accessible to a wide audience.

The latest version, 2.1.1, available for Windows 7, 8, 10, and 11, has shown significant improvements and updates from its previous versions, 2.1, and 1.0. Falling under the 'Home & Hobby' category and 'Bookkeeping-Cataloging' subcategory, SExI-FS addresses the high complexity of traditional agroforestry systems by employing an object-oriented approach. Each tree in the model is an instance of a generic tree class, allowing it to mimic real-to-life behaviors and interactions.

The 3D representation of a one-hectare forest plot allows for an immersive and realistic simulation of competition among trees, mediated by space and light. This feature makes the tool valuable for those exploring various agroforestry management scenarios. The initial strategy aligns well with the two basic tenets of biology, which state that every individual tree differs due to genetics and environment and that interactions are inherently local.

Pros:

• Realistic tree-tree interaction simulation.
• Free to download.
• Suitable for various versions of Windows, including the latest updates.
