Improving Crop Yield and Suitability Mapping by Integrating Crop Growth Models and Remote Sensing

01/07/2024 - 03/07/2024

Crop growth and suitability models are key tools for monitoring, planning, and devising policy strategies for sustainable agrifood systems. Crop simulation tools like APSIM, DSSAT, and AquaCrop are at the forefront of agricultural technology, providing detailed crop growth dynamics at the parcel level under varied environmental, genetic, and management scenarios. Integrating crop models with Earth Observation (EO) techniques to spatialize results in data-limited conditions remains a key step for operational large scale and near-real-time crop monitoring, but significant technical challenges still apply. Enhanced results from this integration can significantly contribute to global platforms like Global Agro-Ecological Zones (GAEZ) by providing more accurate yield estimations and crop suitability maps.

We invite you to join us for a comprehensive exploration of how the integration of crop models and Earth Observation data can enhance crop yield estimation and crop suitability mapping under varying levels of data availability. During this event, we will delve into the functionalities of crop modeling tools such as APSIM, DSSAT, and AquaCrop, discuss the role of remote sensing data in yield estimation, and examine the GAEZ platform for the crop suitability mapping. Our discussions will cover the technical approaches, challenges, and opportunities in this field.

 

The event will take place at the FAO headquarters (Ethiopia Room) in Rome, Italy, and will also be accessible online.
