摘要:The climate changes caused by the rise in the average temperature of the earth are unmistakable. These changes, subject several systems to risks, such as: greater frequency and intensity of extreme climatic events, rising sea levels, among other climate threats. For semi-arid regions, the projections indicate that the climate will become more arid, aggravating drought and increasing desertification processes.

The results points that these actors perceived the risks of climate change, as an aggravation to climate threats with a history of occurrence in the state.
