Greening as strategies to reduce heat stress: Case of Portada de Manchay II, Peru

Peru has high risk for natural disasters due climate changes ,11th place  according to the World Risk Index 2024. Their principal effects are heavy rains and the accelerated melting of Andean glaciers that cause floods, landslides, and prolongation of droughts, affecting food security, access to water, economic development, and health. Planting trees and implementing bioswales can be a strategy for infiltrating water into the soil and promoting shade and vegetable gardening. However, the lack of water for irrigation is a challenge for growing plants and vegetables in arid climates, but it can be managed by harvest fog due to local climate conditions. This study aims to evaluate the benefits of these green areas on microclimatic benefits based on two scenarios: the current (without green areas) and the future (with green areas). Methods: a) field data information (topography, land-uses, urban form, vegetation); b) developing a future scenario based on local necessities; c) quantifying thermal comfort of current scenario and futures using Envi-met data; d) Data analysis. Results show green areas can be reduced by 3 to 5^o C PET. The climate adaptation strategy of planting trees or vegetable gardens can provide shade on sidewalks, reduce thermal surfaces, and control wind direction to maximize green benefits. In addition, it can ensure food security and human health. This work is part of the predictive analysis of the impact of implementing traditional and innovative crop mist in Peru, focusing on the development of sustainable communities.
