Kahina Baha, an independent agricultural engineer based in Carcassonne, helps winegrowers adapt to climate change. She does not hesitate to direct them towards the cultivation of pistachios or olive trees in addition to viticulture.


In Occitania, climatic hazards impact the morale of winegrowers because in certain terroirs, water is very rareconfides Kahina Baha, agricultural engineer and founder of the consulting company Confian’Sol based in Carcassonne. Faced with global warming, there is of course no single solution. There are several that can make it possible to adapt in the short or medium term. I see that winegrowers are making efforts to find new technical routes”.

Among the levers of action to combat climate change, Kahina Baha suggests, at the vine scale, using irrigation, soil management, the establishment of plant covers, cooling by sprinkling or by applying foliar antitranspirants. At the cluster level, this engineer suggests taking action on foliage management, installing shade sails, using kaolinite for its “sun cream” effect, but also installing cover plants and apply antiperspirants.


“In the medium term, and when possible, we must move the vineyard to higher altitudes, choose late-ripening grape varieties and rootstocks that are resistant to drought and heat, continues Kahina Baha. Some winegrowers, when they uproot Merlot, replant, for example, Grenache gris which is more tolerant of water stress”.


Diversification

Adaptation also involves, for Kahina Baha, thinking about diversifying into other agricultural production. During the Meetings of Engaged Winegrowers in Aube, on March 22, she presented the pistachio sector which is beginning to take shape with the creation of the Pistache en Provence association in 2018 then the France Pistache producers’ union in 2021.

A focus was also placed on the company Nectar & Co, which is developing the olive growing sector in Occitania, with a return on investment from the fifth harvest. How do winegrowers react to these suggestions? “They are curious,” replies Kahina Baha. Following the Engaged Winegrowers Meetings, I was contacted by several cooperatives in Occitanie to think about diversification…”.
