This is what they pointed out specialists on a panel organized by the regional office of the Food and Agriculture Organization of the United Nations (FAO)in Santiago de Chile, entitled “Preparing for La Niña, advances and challenges to measure its impact on agri-food systems”, so They asked Latin American countries to remain on alert.
The experts agreed that The periods of transition between the two phenomena that occurred in other decades are no longer occurring and that shortens the time for affected communities to recover and prepare.
“We saw it a year ago: we came out of a Niña and in March we already had some signs of a Boy. Now we are again in March and April with signs of a Girl… We have not been able to recover from the impact of the phenomenon and we quickly went to the opposite“said Yolanda González, director of the International Research Center for the El Niño Phenomenon (CIIFEN).
On the contrary, “if we had a longer time frame towards a normal transition period, we should have a relatively expected ecological response… But This abrupt change probably generates greater stress and from that point of view we have uncertainty about how ecological systems will respond.“said Jaime Letelier, head of Oceanography at the Fisheries Development Institute (IFOP) of the Chilean government.
El Niño is independent of climate change, but Experts have observed changes in the way the phenomenon is presenting itself such as, for example, an increase in rainfall, heat waves and periods of drought, as explained by the FAO technical team.
Rapid transitions between El Niño and La Niña They can also be correlated with climate change, although science does not yet allow causalities to be established. unequivocally, they added.
The patterns of El Niño and La Niña have consequences in different parts of the planet and in Latin America they have impacted the production of key crops such as wheat, rice and corn.causing negative effects on the economy of countries, highly dependent on raw materials.
