Tridge summary

The Ministry of Agriculture in Brazil has introduced the Climate Risk Agricultural Zoning (Zarc) for citrus cultivation, considering climatic risks of 20%, 30%, and 40% for existing and new orchards. This is the first zoning to consider climatic risks, along with the productive cycles of early, mid-season, and late fruits. The researcher, Maurício Coelho, explains the variations in fruit development time due to air temperature differences. The zoning results show that most production limitations are due to water deficit, especially in regions of the cerrado and caatinga biomes. Zarc is an agrometeorological study used by financial institutions for credit and rural insurance evaluation, indicating climatic risks for various crops in different regions of Brazil.

This is the first zoning for citrus cultivation that considers climatic risks of 20%, 30% and 40% for orchards in production and for the installation of new areas and not only the climatic aptitude, as was done previously. The measure was published in the Official Gazette (DOU), on Wednesday, 14, Thursday, 15, through Ordinances number 19 to 49.
