L'temperature increase because of climate change It is not only bringing heat waves but is also creating serious problems for the global production of tomatoes destined for industrial processing which could fall by 6% by 2050
Among the most affected areas there is also theItaly, which with over 6 million tons of processed product per year is the second largest producer in the world after the United States and before China.
The alert was raised by a study conducted by an international group coordinated by Domenico Ronga ofUniversity of Salerno and led by Davide Cammarano of Aarhus University in Denmark.
The results are published on nature food. “This is the first study to evaluate the impact of climate change on processing tomatoes in the three largest producers in the world, namely the United States, Italy and China, which together represent 65% of global production“, He explains Cammarano.
The researchers evaluated the trend of crop yields in the case of low, high or very high greenhouse gas emissions: for each scenario, they considered five climate models that predict different temperature and rainfallThe results show that California and Italy will be the hardest hit areas.
In our country, in particular, for every degree of increase in temperature, production will decrease on average by 0,4 tons per hectare in the Foggia area and by 0,3 tons per hectare in Emilia Romagna, with even more worrying (and uncertain) projections for 2100.
