However, facing a dual challenge of climate change and continuing urban growth, Lima's water utility agency, SEDAPAL, is increasingly integrating elements of Andean water governance systems-commonly referred to as the sowing and harvesting of water-in its future strategies to maintain urban water security.
In Lima, Peru, the model for water infrastructure development has long been a technocratic one, driven by values such as efficiency and modernization.
Our combined results emphasize the key role played by residential yards providing ecosystem services in tropical cities and call for further efforts to manage private and public urban forests in ways that may ensure their resilience to mitigate extreme climate events, provide multiple ecosystem services, and promote long-term urban sustainability.Īs urban infrastructures are built to last for decades, each infrastructure contains the anticipation for an uncertain future: a city-to-come, often built on capitalist and modernist dreams. Food provision, an important service provided by a large proportion of yards before the hurricane, reported the highest reduction (41.9%) while carbon storage was the service that changed the least (9%). Changes in vegetation structure translated into substantial reductions in ecosystem services. Yard species composition was dominated by non-native species and this trend did not change with hurricane disturbance. We detected a 27% reduction and 31% mortality of standing stems, and a significant reduction in plants health. We found that hurricane disturbances significantly altered the structure but not the composition of yard vegetation. We used these surveys to compare vegetation structure and composition (including species-specific mortality and damage rates) and to quantify changes in the ecosystem services provided by these yards. Here we analyzed pre-and post-hurricane vegetation surveys in 52 residential yards in San Juan to assess urban forest responses after Hurricanes Irma and María impacted Puerto Rico in 2017. Understanding how urban forests are responding to hurricane disturbances is crucial to improve their design, management, and resilience. However, they are also vulnerable to the impact of extreme climate events like hurricanes. Urban forests are valuable spaces for species conservation, protection of local biodiversity and provision of ecosystem services.
