Abstract: Abstract This research was done through spatial analysis to verify whether the use of public policies in the sugarcane sector contributes to the expansion of the functional connectivity of the landscape. In this context, our paper aimed to analyze the role of the Agro-environmental Protocol for the Sugar-Alcohol Sector in landscape connectivity based on two main questions: (1) Did the actions taken by the sugar-energy sector signatory towards the protocol cause an increase in forest patches in riparian Permanent Preservation Areas (PPA)? (2) After signing the protocol, was there an improvement in functional connectivity, and if so, what was the improvement in functional connectivity within all restored permanent preservation areas? As such, we compared the evolution of riparian PPA based on functional connectivity indices for the years 2006, 2020 and analyzed these indices in a hypothetical scenario with all PPA restored. Connectivity analyses have shown significant differences between the analyzed scenarios. However, the indices have shown extremely low values in all scenarios. We conclude that even though the actions proposed by the public policy may have resulted in an increase in the total forested area and have positively affected connectivity, they may be insufficient to affect the resilience of the natural landscape.
