For those who grow crops, it is very important to know where the shade is prominent on their field and to adjust their sowing or planting behaviour accordingly. But other parameters are also important and can help determine the effective use of agricultural land. It is therefore very important to map these parameters, including for policy.

Sustainable agriculture also involves close monitoring of climate change. This is the only way to recognise patterns and make predictions in the medium and long term. By using the latest techniques of data analysis provided by, for example, satellite images, it is increasingly possible to identify and monitor the cultivation of crops on a large scale and over larger areas.
