Satellite remote sensing technology can help to predict barley yields, a critical aspect of ensuring food security, as the world population is expected to increase to 9.7 billion by 2050. The European Space Agency's Sentinel-2 and Sentinel-1 (SAR) satellites provide valuable information about the condition of crops, including barley, by analyzing the spectral signatures of crops. Sentinel-2 captures high-resolution imagery of the Earth's surface, which can be used to identify and monitor vegetation, while Sentinel-1 (SAR) provides information about the structure and moisture content of crops, including barley. By combining data from these satellites with weather and environmental data, scientists can develop models that accurately predict barley yields, helping farmers make informed decisions to improve yields and reduce environmental impact. The technology is also useful in detecting pests and disease, enabling preventative measures to be taken before they impact yields.
