Vines are threatened
By 2050, the European vine-prone land will have decreased by an average of 68% due to global warming.
This is true for most world wines of which Mediterranean, Californian, Australian and South-African wines.
Consequences are already huge:
- Harvests happen earlier;
- Water stress, more acute some summers, dramatically reduces yields;
- Increase demand in water;
- Modification of the grape quality and of the aromatic properties of wines: maturation period subjected to high temperatures;
- Grapes reach early maturity;
- Increase in sugar level in grape and thus of the alcoholic content;
- Higher climate risks, etc.

Advantages of agrivoltaism for the vine
The Sun’Agri solution provides smart shadings in order to limit excessive light and heat:
– Reduction of wines’ alcohol content;
– Preservation of aromatic properties of wines;
– Alternative to irrigation during dry periods for vineyards far from water sources: up to 20% in water saved;
– Preservation and even increase in yields : tackles recurring reductions of yield related to climate change.
