The cultures of castor oil plant, sunflower, cotton, orange, yuca and sugarcane have great importance in many regions of Brazil, and also represent a substantial part of the country's agricultural gross domestic product (GDP). They are cultures that, in most cases, occupy a considerable territorial extension with uniform surfaces, a fact which might cause them to suffer accentuated impacts of the global climate change, and subsequently cause ripple effects in food safety and other important sectors that compose the Brazilian commercial balance. This project's main goal is to understand the potential impacts of global climatic changes over these cultures and their geographical production, from the point of view of different scenarios. It also aims to propose adaptation and/or mitigation measures for the maintenance of current production systems. The studies are specific for each culture, they respect each peculiarity and take into account the available knowledge regarding the effects of environmental changes, such as increase in CO2 concentration in the atmosphere, increase in temperature, and rainfall variability. It is a goal to propose future sceneries for the cultures of yuca, cotton, castor oil plant, sugarcane, and sunflower, based in ecophysiological models and of climate risk zoning. It also hopes to identify the main vulnerabilities of the studied production systems and subsequently to propose adaptation measures to decrease impacts and improve the production processes in Brazil.
