- •
Irrigated sunflower productivity is 3.5 times higher than rainfed.
- •
The impacts depend of the functional unit (1 kg seeds vs 1 ha cultivated land).
- •
Impacts (no LUC) of irrigated sunflower have higher uncertainty than rainfed.
- •
Irrigated and rainfed (no fertilizers) have similar eutrophication and GHG per kg.
- •
Rainfed has significantly lower impacts per ha than irrigated sunflower.
