Olive Quick Decline Syndrome in Apulia, Italy

The detection of the quarantine plant pathogen Xylella fastidiosa on centuries-old Olive Tree In Apulia sparked a socio-environmental conflict among different actors.


Description:

Apulia has a significant heritage of centuries-old olive groves. In this social context, an olive tree is no ‘ordinary’ tree, they are not just perceived as a source of income central to local agri-food production, but take on an exquisitely symbolic and identity-making importance.

Development of alternatives:Developing a set of alternatives to this phytosanitary emergency is and continues to be a matter of discord.
This process revolves around two main different views on how to deal and live with the bacterium Xylella Fastidiosa.
The first alternative is proposed by a large part of the scientific expertise and backed by some of the agricultural entrepreneurs. In their view, the only suitable option, for the moment, is to concentrate on the research for resistant/tolerant cultivars. It has been noted that some cultivars like "Leccino" and "Fs17" (also known as "Favolosa") demonstrated a resistance to the bacterium, therefore reducing the possibility for the plant to show symptoms of decline.
Local Social Movements strongly oppose this alternative, besides underlying the possibility for price speculations on these new resistant cultivars, Social Movements complain that nothing has been done in order to find a "cure" for the diseased tree.
Movements propose what they define as the "360°Approach", an approach that does not look exclusively at the pathogen, but to the entire plant system, highlighting the importance of researching on alternative or contributory causes (i.e. fungi, soil pollution, and overuse of agro-chemical products) with the ultimate goal of curing olive orchards instead of eradicating them or replace them with other cultivars.
In this regard, in addition to advocating for “good farming practices”, movements also support various remedies such copper and zinc-based bio-fertilizers, the use of inoculum of endo- and/or ecto-mycorrhizae and beneficial fungi and bacteria (to restore the soil microbiota), and a wide range of ecologically sustainable techniques which, according to them, represent a necessary alternative to pursue in order to find a solution to this plant disease.
Do you consider this an environmental justice success? Was environmental justice served?:No
Briefly explain:The controversy goes on.

"Zona avvelenata" Poisoned Zone It is not that rare to encounter these signs in south-eastern apulia. Enviornmental Movements claim that soil pollution may play a role in the Olive Quick Decline Syndrome. On the other hand,, experts often say that the bacterium Xylella affect every soil, regardless of the agricultural techniques used.
