Perspectives of climate change impacts for agricultural crop areas in central amazon

Odontogenic This study aimed to assess the impact of warming up to 5 °C in air temperature in Santarém-PA region and other meteorological variables, such effect of climate change highlighted by IPCC (2007) using a biosphere-atmosphere interaction model (SiB2), using LBA data and calibration of the Biosphere-Atmosphere SiB2 interaction model proposed by Llopart (2009), in order to infer possible changes on soybeans and maize productivity in the region due to these changes. The study showed that the SiB2 model calibrated to the Tapajos National Forest can simulate real future scenarios for the region. The simulations enabled to realize that the changes in the scenarios will have a negative effect on soybean yield in the region when analyze the limiting factors. As for the maize, future scenarios don’t present a major risk of production losses, given the physiologic and anatomical characteristics of the culture.
