Demystifying normalized difference vegetation index (NDVI) for greenness exposure assessments and policy interventions in urban greening

Most nature and health research use the normalized difference vegetation index (NDVI) for measuring greenness exposure. However, little is known about what NDVI measures in terms of types (e.g., canopy, grass coverage) within certain analysis zones 500 m buffer). Additionally, exploration needed to understand how interpret changes average per 0.1 increments) exposure relation amount types. In this study, we aimed explore amounts best explain values indicate different coverages. We used spatial modeling sample mean percentages locations Greater Manchester case study area. fitted linear, nonlinear, mixed multivariate univariate generalized additive models (GAMs) multiple scales identify relationships between Our results showed that individual mostly follow nonlinear trends. found canopy shrubs coverage exhibited a greater influence on than at 300 indicating are sensitive various buffer zones. also identified increment lower, mid, high ranges might be associated with varying total greenspace percentage For instance, buffer, an lower range from 0.2 0.3) 17% increase percentage. Overall, interpreting urban greening interventions would require careful evaluation relative quantities

Racial, Ethnic, and Socioeconomic Disparities in Multiple Measures of Blue and Green Spaces in the United States

Environmental Health Perspectives, Journal Year: 2023, Volume and Issue: 131(1)

BACKGROUND: Several studies have evaluated whether the distribution of natural environments differs between marginalized and privileged neighborhoods.However, most restricted their analyses to a single or handful cities used different environment measures.OBJECTIVES: We are inequitably distributed based on socioeconomic status (SES) race/ethnicity in contiguous United States.METHODS: obtained SES data (2015-2019) for all U.S. Census tracts.For each tract, we calculated Normalized Different Vegetation Index (NDVI) 2020, NatureScore (a proprietary measure quantity quality elements) 2019, park cover blue space 1984-2018.We generalized additive models with adjustment potential confounders spatial autocorrelation evaluate associations NDVI, NatureScore, cover, odds containing tracts (n = 71,532) urban 45,338).To compare effect estimates, standardized so that beta coefficients presented percentage increase decrease standard deviation (SD).RESULTS: Tracts higher had space.For example, highest median household income quintile NDVI [44.8% SD (95% CI: 42.8, 46.8)] [16.2% 13.5, 19.0)] compared lowest quintile.Across tracts, lower non-Hispanic White individuals Hispanic were associated NatureScore.In observed weak positive Black cover; did not find any clear Hispanics.

Nature-based biopsychosocial resilience: An integrative theoretical framework for research on nature and health

Environment International, Journal Year: 2023, Volume and Issue: 181, P. 108234 - 108234

Published: Sept. 27, 2023

Nature-based solutions including urban forests and wetlands can help communities cope better with climate change other environmental stressors by enhancing social-ecological resilience. Natural ecosystems, settings, elements affordances also individuals become more personally resilient to a variety of stressors, although the mechanisms underpinning individual-level nature-based resilience, their relations are not well articulated. We propose 'nature-based biopsychosocial resilience theory' (NBRT) address these gaps. Our framework begins suggesting that refer both: a) person's set adaptive resources; b) processes which resources deployed. Drawing on existing nature-health perspectives, we argue nature contact support build maintain biological, psychological, social (i.e. biopsychosocial) resilience-related resources. Together can: i) reduce risk various (preventive resilience); ii) enhance reactions stressful circumstances (response resilience), and/or iii) facilitate rapid complete recovery from stress (recovery resilience). Reference three supports integration across familiar pathways involving harm reduction, capacity building, restoration. Evidence in theory, potential interventions promote issues require further consideration discussed.

Exposure Ecology Drives a Unified Understanding of the Nexus of (Urban) Natural Ecosystem, Ecological Exposure, and Health

Ecosystem Health and Sustainability, Journal Year: 2024, Volume and Issue: 10

Published: Jan. 1, 2024

The intersection of ecology and exposure science with health concerns has led to a gradual infiltration these disciplines. Exposure (urban) natural ecosystems, defined as ecological exposure, proven be substantially beneficial health, providing more effective preventive measures than dealing downstream consequences the disease. Besides, eco-environment & field have shifted its paradigm from focusing on negative environmental exploring positive benefits exposure. However, unified framework that integrates nexus ecosystem, is still lacking. To address challenges, here, we propose new (discipline), (EE), reviewed relevant studies. We suggest domain scope EE include subject-reality, object-reality, subject-virtual, object-virtual dimensions all previous studies can covered within this coordinate frame. analyze trends shortcomings each explain pathways including reduction, restoration, promotion capacity, potential harm. Furthermore, discuss theoretical basis for formation EE, well EE-derived hypotheses, implications, connections other related fields. In short, EE-driven holistic critical review enhances our understanding frontier topic substantially, it serve realizing Sustainable Development Goals (SDGs).

Several systematic reviews support nature-based interventions (NBIs) as a mechanism of enhancing mental health and wellbeing. However, the available evidence for effectiveness these is fragmentary mixed. The heterogeneity existing significant fragmentation knowledge within field make it difficult to draw firm conclusions regarding NBIs. This can only limit development personal planetary wellbeing, potentially resulting in ineffective ill-targeted investment decisions.

Exploring green gentrification in 28 global North cities: the role of urban parks and other types of greenspaces

Environmental Research Letters, Journal Year: 2022, Volume and Issue: 17(10), P. 104035 - 104035

Published: Sept. 20, 2022

Abstract Although cities globally are increasingly mobilizing re-naturing projects to address diverse urban socio-environmental and health challenges, there is mounting evidence that these interventions may also be linked the phenomenon known as green gentrification. However, date empirical on relationship between greenspaces gentrification regarding associations with different greenspace types remains scarce. This study focused 28 mid-sized in North America Western Europe. We assessed improved access of (i.e. total area parks, gardens, nature preserves, recreational areas or greenways [i] added before 2000s [ii] 2010s) processes (including for 2000s; 2010s; [iii] throughout decades each small geographical unit city. To estimate associations, we developed a Bayesian hierarchical spatial model city time period maximum three models per city). More than half our showed parks—together other factors such proximity center—are positively associated processes, particularly US context, except historically Black disinvested postindustrial lots vacant land. find newly designated preserves negatively when considering 2010s US. Meanwhile, new spaces greenways, research shows mixed results (some positive, some negative no effect associations). Considering environmental benefits projects, should keep investing improving park while simultaneously implementing anti-displacement inclusive policies.
