Spatially-optimized urban greening for reduction of population exposure to land surface temperature extremes

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 22, 2023

The population experiencing high temperatures in cities is rising due to anthropogenic climate change, settlement expansion, and growth. Yet, efficient tools evaluate potential intervention strategies reduce exposure Land Surface Temperature (LST) extremes are still lacking. Here, we implement a spatial regression model based on remote sensing data that able assess the LST urban environments across 200 surface properties like vegetation cover distance water bodies. We define as number of days per year where exceeds given threshold multiplied by total exposed, person ⋅ day. Our findings reveal plays considerable role decreasing extremes. show targeting high-exposure areas reduces needed for same decrease compared uniform treatment.

The Superblock model: A review of an innovative urban model for sustainability, liveability, health and well-being

Environmental Research, Journal Year: 2024, Volume and Issue: 251, P. 118550 - 118550

Published: March 1, 2024

Current urban and transport planning practices have significant negative health, environmental, social economic impacts in most cities. New development models policies are needed to reduce these impacts. The Superblock model is one such innovative that can significantly through reshaping public spaces into more diverse uses as increase green space, infrastructure supporting contacts physical activity, prioritization of active mobility transport, thereby reducing air pollution, noise heat island effects. This paper reviews key aspects the model, its implementation initial evaluations Barcelona potential international uptake Europe globally, focusing on climate, lifestyle, liveability health aspects.

Climate change is elevating nighttime and daytime temperatures worldwide, affecting a broad continuum of behavioral health outcomes. Disturbed sleep plausible pathway linking rising ambient with several observed adverse human responses shown to increase during hot weather. This systematic review aims provide comprehensive overview the literature investigating relationship between temperature valid outcomes measured in real-world settings, globally. We show that higher outdoor or indoor are generally associated degraded quality quantity worldwide. The negative effect heat persists across measures, stronger hottest months days, vulnerable populations, warmest regions. Although we identify opportunities strengthen state science, limited evidence fast adaptation suggests induced by climate urbanization pose planetary threat sleep, therefore health, performance, wellbeing.

Green spaces provide substantial but unequal urban cooling globally

Climate warming disproportionately impacts countries in the Global South by increasing extreme heat exposure. However, geographic disparities adaptation capacity are unclear. Here, we assess global inequality green spaces, which urban residents critically rely on to mitigate outdoor stress. We use remote sensing data quantify daytime cooling greenery warm seasons across ~500 largest cities globally. show a striking contrast, with having ~70% of North (2.5 ± 1.0 °C vs. 3.6 1.7 °C). A similar gap occurs for benefits received an average resident these (2.2 0.9 3.4 This is due discrepancies space quantity and quality between South, shaped socioeconomic natural factors. Our analyses further suggest vast potential enhancing while reducing inequality.
