One of the world’s major issues is climate change, which has a significant impact on ecosystems, human beings, agricultural productivity, water resources, and environmental management. The General Circulation Models (GCMs), specially the recently released (coupled model intercomparison project six) CMIP6 are very indispensable to understand and support decision makers to identify adaptation strategies in response to future climate change in a basin. However, proper selection of skillful GCMs and future climate assessment is a prior task to climate impact studies.

Vegetable extraction has been considered a new paradigm of adequate development for the Amazon Region by ecological movements, international organizations, and foreign governments. This study evaluates whether the supply of extractive products transformed into economic value can ensure the livelihood of families and prevent deforestation.
