It is in this context that government, academic institutions and local civil society have taken important steps and often joint action toward mitigation and adaptation. Federal funding included USD 20 billion of disaster recovery funding with USD 8 billion allocated for adaptation and resilience projects, such as flood risk mitigation. During the year 2020, the Federal Emergency Management Agency  approved USD 13 billion to rebuild the power grid and education system . These programmes allow communities and local governments to plan and implement strategies and build new infrastructure that reduces risks and builds long-term adaptive capacities. The Government of Puerto Rico also approved two key climate adaptation policies in 2019. The Puerto Rico Mitigation, Adaptation and Resilience to Climate Change Law  established, for the first time in the island's history, a legal framework that acknowledges that the climate is changing and threatens the quality of life. The law recognises important scientific projections for the island, including an increase of 0.5 to 1 m in sea levels by 2015, maximum temperatures of up 2.5℃ and precipitation decrease of up to 50% by 2100 . The law generated the formation of an Expert and Advisory Committee on Climate Change to develop the plan with specific recommendations and present it to the Legislature within a year of the passing of the law in 2020. Along with strategies to specifically protect and build the resilience of urban and rural communities to future climate disasters, the law establishes SDGs, including water and food security, urban planning and densification, and transition to renewable and alternative forms of energy. The energy target is reinforced by another key state policy approved in 2019 in response to the failed energy infrastructure during Hurricane María, the Puerto Rico Energy Public Policy Act . This law calls for a transition to 100% renewable and alternative energy by 2050.
