Conteúdo: | Bamboo has an important role in international commerce due to its diverse uses, but fewstudies have been conducted to evaluate its climatic adaptability. Thus, the objective of this study was to construct an agricultural zoning for climate risk (ZARC) for bamboo usingmeteorological elements spatialized byneural networks.Climatedata includedair temperature (TAIR, °C) and rainfall (P) from 4947 meteorological stations in Brazil from the years 1950 to 2016. Regions were considered climatically apt for bamboo cultivation when TAIR varied between 18 and 35 °C, and P was between 500 and 2800 mm year&#8722;1, or PWINTER was between 90 and 180 mm year&#8722;1. The remainder of the areas was considered marginal or inapt for bamboo cultivation. A multilayer perceptron (MLP) neural network with amultilayered Bbackpropagation^ training algorithmwas used to spatialize the territorial variability of eachclimatic element for thewhole area ofBrazil.Usingtheoverlappingof theTAIR,P, andPWINTERmaps preparedbyMLP, and the established climatic criteria of bamboo, we established the agricultural zoning for bamboo. Brazil demonstrates high seasonal climatic variabilitywith TAIR varying between 14 and 30°C, andPvarying between< 400 and 4000mmyear&#8722;1.TheZARCshowed that 87%of Brazil is climatically apt for bamboo cultivation. The states that were classified as apt in 100% of their territories were Mato Grosso do Sul, Goiás, Tocantins, Rio de Janeiro, Espírito Santo, Sergipe, Alagoas, Ceará, Piauí, Maranhão, Rondônia, and Acre. The regions that have restrictions due to lowTAIR represent just 11% of Brazilian territory. This agroclimatic zoning allowed for the classification of regions based on aptitude of climate for bamboo cultivation and showed that 71% of the total national territory is considered to be apt for bamboo cultivation. The regions that have restrictions are part of southern Brazil due to low values of TAIR and portions of the northern region that have high levels of P which is favorable for the development of diseases.
