Improving Food Security and Crop Yield in Senegal Through Machine Learning
Project completed! Results attached!
A challenge initiated to help farmers know where to add water or fertilizer using data such as soil PH, temperature, and moisture levels, combined with other data sources. The data and predictions will also help to decide where to invest, and help strengthen the understanding of crop losses while maximizing revenues and minimizing losses.
The Global Partnership for Sustainable Development Data (GPSDD) seeks to leverage machine learning to help farmers cope with increasingly erratic weather, model the fastest route to markets and mobilities across livelihood zones, and detecting problems in fields with drones and others tools. GPSDD seeked to leverage machine learning to help farmers improve crop yield prediction.
At a time where the world needs to produce more with fewer resources, AI could help to transform agriculture worldwide and especially in Senegal. The ability of agricultural equipment to help actors better think, predict, and advise farmers via a variety of AI applications presents Senegal with the potential to achieve food security in the country. Senegal is among those hardest hit by climate change, according to scientists, with populations that depend largely on agriculture losing their livelihoods due to worsening and recurrent floods and droughts.
Using technology, we can now, have better results to know what is going to happen and where in Senegal while promoting a data-driven agricultural system. Data such as soil PH, temperature, and moisture levels, combined with other data sources from ANSD and other stakeholders such as DAPSA, CSE, ANACIM, CSA, could be processed to show exactly when and where farmers should add water or fertilizer. The data will also help to decide where to invest, and help strengthen the understanding of crop losses while maximizing revenues and minimizing losses.
In these two months, Omdena’s collaborators were able to implement a Deep Learning model that predicts crop yield in Senegal following this schema:

The data used to get crop yield prediction using deep neural networks:
Remote sensing data downloaded with Google Earth Engine (GEE)
Ground truth crop yield data: we had yield data collected by IPAR for the production of maize, rice, and millet in 2014
Data engineering and pre-processing were used with the satellite imagery datasets they collected, before feeding them into Convolutional Neural Networks for a Transfer Learning process.

Then the team created an application using open-source satellite images to identify the crops and estimate the yields for any given area.
