The International Citrus Congress comes to an end after a week of important discussions about sustainability, the main theme of the congress.
There were 18 plenary sessions that discussed various issues affecting the citrus community in the world.
One is the HLB (also known as citrus greening), a disease that worries producers and researchers because it is difficult to fight and it is advancing through the orchards.
There were many talks, many of them on genetically modified plants which are tolerant to greening. These varieties represent a huge breakthrough in genetic technology and should be tested soon in the field.
According to the researchers who attended the event, when speaking in a project of sustainability, there is no better tool than breeding to combat HLB, and this has been an important contribution of genetic engineering.
Other issues were also highlighted in this week's congress:the pursuit of sustainability and the impact of the activity on the world's natural resources;the need to improve the mineral nutrition in the field, and the impact of climate change.
The last one has such an impact on citrus crops that a whole event was devoted to the subject. Eduardo Fermino, IAPAR researcher and one of the ICC 2016 organizers, global warming - and consequently climate change - is a real event.
"We are dealing here with a situation that could compromise life on our planet. And the citrus activity is a major component of it. We have to be aware to advance the issue of sustainability".
So also the choice of the International Citrus Congress theme in Brazil: "Sustainable Citriculture: the role of applied knowledge."
"For us sustainability goes far beyond environmental sustainability. This is sustainability in a whole: social-economic, business and the environment, " said Fermino.
The International Citrus Congress is held every four years in different countries.
The next event is scheduled for 2020 in the city of Mersin, Turkey.
The theme of the 14th International Citrus Congress is: "Reframing Citrus: Better connections for the future."
Turkey is now the eighth largest producer of citrus in the world, with annual production of 4.2 million tons. Forty percent of production is exported to the world.
