In Portugal, the mediterranean characteristics of the climate turns water supply for irrigation an important issue in agricultural activity. Plants vegetative grow and maturation usually happens in summer time, when high levels of temperature and solar radiation occur, together with almost null rainfall.

Sentinel-2 ask: what farmers want?

• increase production

ۥ waste less

How can Sentinel-2 help?• Integration with hydrologic and weather models to

estimate flood and drought• Get more images and fast (hours???)• Validate satellite images with yield maps• Include other crops (tomato, rice, olive trees,

vineyards, cork tree, pine trees, non irrigated crops)

• High resolution• Soil map cartography
