“…The study was developed throughout the Brazilian territory, with an extension of 8,547,403.5 km 2 . Among the main economic activities, there is an emphasis on the agribusiness sector responsible for 47% of exports and a share of around 37% of GDP (Gross Domestic Product) (Guilhoto 2004), with great emphasis on grain production (soybeans and maize) and livestock in the Midwest region (Pinto et al 2018) and fruit production producing approximately 40 million tons in 2017 (Neves et al 2011;dos Santos et al 2018). Also, there is a predominance of ve biomes in the country, Amazon, Pantanal, Cerrado, Atlantic Forest, and Pampas, de ning different vegetation characteristics (Overbeck et al 2007).…”

Climate classification systems are tools capable of facilitating the analysis, grouping, delimitation, and dissemination of climatic characteristics of a region, contributing to the delimitation of areas of fitness in the agricultural sector and validation of various models of climate change. Thus, we seek to determine life zones for Brazil using the ecological classification of Holdridge (1967) in different scenarios of climate change. A 30-year historical series (1989-2019) of climatic data of average air temperature (° C) and rainfall (mm) was used for the entire Brazilian territory, obtained through the National Aeronautics and Space Administration / Prediction of World platform Wide Energy Resources - (NASA/POWER). Potential evapotranspiration (PET) was estimated by the method of Camargo (1971) using combinations between annual precipitation, average annual biotemperature, average annual basal biotemperature, and the relationship between evapotranspiration and altitude, the life zones for the Holdridge (1967) system were defined. The scenarios used were based on the IPCC (2014) projections. The average temperature in Brazil ranges from 13.1 to 28.0 ° C and the average annual precipitation is 1467 (± 46.91) mm. In the current scenario for the classification of Holdridge (1967) the predominant zone of life is the humid basal tropical forest in 60.57% of the territory. The increase in temperature causes a predominance of the living zones Basal tropical rainforest in 48.92% for S2 and Basal tropical rainforest in 48.95% in S3, the reduction in precipitation S4 generates the predominance of the living zone Basal tropical forest drought in 49.87%, with the increase in precipitation S5 there is a predominance of the zone of life Low humid basal tropical forest in 50.12% of the territory. The great variability of the obtained life zones makes the Holdridge system a useful tool to validate climate change scenarios.

Climate Classification System (CCS) is an important tool for validating climate change models, subsidizing the characterization of new areas suitable or unfit for agricultural activity according to future climate change scenarios. This study aims to classify the climate of the Brazilian territory in the various climate change scenarios of the IPCC through the Thornthwaite system (1948). We used a 30-year historical series of climatic data of average air temperature (°C) and rainfall (mm), obtained from the National Aeronautics and Space Administration/Prediction of Worldwide Energy Resources platform (NASA/POWER). Potential evapotranspiration (ETP) was estimated by the method of Camargo (1971); the climatological water balance (CWB) was calculated by the method of Thornthwaite and Mather (1955), using 100 mm of soil water storage capacity. CWB extracts were combined for classification by Thornthwaite (1948). The scenarios used were based on the IPCC (2014) projections and the study of Pirttioja et al. (2015). The Brazilian territory had an average air temperature of 22.20 °C (± 3.20) °C and annual precipitation of 1987 mm (± 725) mm. The climatic classification of Thornthwaite presented 108 climatic classes for the current scenario with a more significant predominance of the classes ArAʹaʹ, B4rAʹaʹ, and B3rAʹaʹ representing 20.54%, 15.62%, and 9.46% of the Brazilian territory, respectively. The climate class ArAʹaʹ had 39.20% in the North and 14.97% in the Midwest. The South region has a predominance of 24.31% for the class ArBʹ3aʹ. In the Southeast and Northeast, the climate classes B2rBʹ3aʹ and DdBʹ2aʹ represented 14.80% and 15.26% of the regions, respectively. The S5 scenario was considered more favorable to establishing crops, with 48.04% of Brazil represented by the climate class ArAʹaʹ. Furthermore, the most catastrophic scenarios for crops were S3 and S4, promoting Brazil a predominance of classes B3rAʹaʹ in 18.02% and B1rAʹaʹ in 21.04%, respectively, favoring the occurrence of arid and dry climates in large part of the Brazilian territory.
