The role of Botanical Gardens is presented in its biodiversity conservation and climate change dimensions in the context of the 2030 Agenda for Sustainable Development framework (UN 2015). Although gardens date back thousands of years to China's Zhou dynasty, 1122-249 BCE (Chen and Sun 2018), the modern concept of a Botanical Garden originated in Europe; the oldest is the Orto Botanico di Pisa founded in 1544, which continues to operate today. Botanical gardens are public, private, or associative institutions that maintain collections scientifically ordered of plants, documented and labeled, for research, but also for education and recreation (The Botanic Gardens Conservation Strategy, IUCN-BGCS and WWF 1989). Climate change (CC) refers to changes in Earth's weather patterns, mainly associated with changes in Earth's average atmosphere temperature due to the increase of carbon dioxide (CO 2) in the atmosphere (McPherson and Simpson 1999), but also related to wind and rainfall changes. Phenological events are seasonal activities of living organisms driven by environmental factors. Plants, for example, are adapted in mid-latitudes to a seasonal climate that includes cold-warm phases and fluctuations of light (Schwartz and Reiter 2000). As mentioned by Schwartz and Reiter (2000) phenological events, such as the first leaf appearance or flower bloom, can serve as markers to monitor changes in plants resulting from climate change. Green Infrastructure is defined as the range of measures that use soils and vegetation to utilize the natural cycle of the water (e.g., infiltration; evapotranspiration) to reuse it (Section 502 Clean Water Act, United States Environmental Protection Agent; https://www.epa.gov/lawsregulations/summary-clean-water-act).
