Addressing green space deficits in segregated neighborhoods is a promising prevention strategy. This study assessed the potential for reducing firearm violence disparities by increasing access to tree cover. Units of analysis were census tracts in six U.S. cities (Baltimore, MD; Philadelphia, PA; Richmond, VA; Syracuse, NY; Washington, DC; Wilmington, DE). We measured segregation using the index of concentration at the extremes (ICE) for race-income. We calculated proportion tree cover based on...AuthorsJonathan Jay, Michelle Kondo, Vivian H.

- Depression and other mental health conditions are consistently among the top ten contributors to the global public health burden (Patel et al., 2018). Between 1990 and 2019, the number of disability-adjusted life-years due to mental disorders world-wide increased from 80.8 million to 125.3 million (GBD 2019 Mental Disorders Collaborators, 2022). This mental health burden is not experienced equally between social groups, with lower-income and other marginalized groups often bearing a disproportionately high burden (Ridley et al., 2020). These inequalities may be explained by unjust systems...AuthorsMichelle Kondo, Russell K. McIntire, Usama Bilal, Leah H. SchinasiSourceHealth & PlaceYear2022
- Peatlands have acted as net CO2 sinks over millennia, exerting a global climate cooling effect. Rapid warming at northern latitudes, where peatlands are abundant, can disturb their CO2 sink function. Here we show that sensitivity of peatland net CO2 exchange to warming changes in sign and magnitude across seasons, resulting in complex net CO2 sink responses. We use multiannual net CO2 exchange observations from 20 northern peatlands to show that warmer early summers are linked to increased net CO2 uptake, while warmer late summers lead to decreased net CO2 uptake. Thus, net CO2 sinks of...AuthorsT. Hirano, E. R. Humphreys, G. Kiely, Randy Kolka, T. Laurila, P. G. Leahy, A. Lohila, I. Mammarella, M. B. Nilsson, A. Panov, F. J. W. Parmentier, M. Peichl, J.

- Several recent longitudinal studies have found that exposure to the natural environment is associated with lower non-accidental mortality. However, most of these studies used the normalized difference vegetation index (NDVI) as an exposure metric; and because NDVI might not be sensitive enough to adequately capture changes in urban vegetation, these studies might lack true longitudinal variation in exposure. Therefore, we used a natural experiment to assess the impact of 30 years of tree planting by the nonprofit Friends of Trees on non-accidental, cardiovascular, lower-respiratory, and...AuthorsGeoffrey Donovan, Jeffrey P.

- We used publicly available land-cover datasets (1921, 1947, 1976, 1992, 2001, 2006, 2014) to assess land-cover change on Babeldaob Island, Republic of Palau. Land-cover data were organized, classified, and summarized by area and percentage of island cover for forest, mangrove, non-forest vegetation, and non-vegetation. Japanese colonial administration of the island between 1921 and 1947 included industrial mining and agriculture, which reduced total non-mangrove forest cover by 16%. Temporal vegetation cover dynamics from 1947 through 2014 indicate unassisted forest regeneration of 12%...AuthorsJulian Dendy, Paul Collins, Dino Mesubed, Susan Cordell, Christian P.

- Sea level rise (SLR) is among the climate-change-related problems of greatest concern, threatening the lives and property of coastal residents and generating far-reaching economic and ecological impacts. We project that SLR will lead to an increase in the rate of new housing construction to replace destroyed structures, impact global wood products supply and demand conditions, and cause changes in global forest sector carbon mitigation potential. Findings indicate that 71 million new units will be built by 2050 to accommodate the SLR-affected global population. More than two-thirds of...AuthorsPrakash Nepal, Jeffrey P. Prestemon, Linda A.

- Cellulose nanomaterials derived from wood, plants, and other organisms provide mechanical reinforcement to a wide variety of polymers. The reproducibility and uniformity of these bioderived and biodegradable nanomaterials makes them suitable for use in existing petrochemical-derived polymers and resins in which relatively simple and pure molecules are used. The composites benefit from improved mechanical, thermal, rheological, and other properties while imparting biobased content (new carbon), thereby sequestering carbon in a multitude of products. The refractive index match between...AuthorsGregory Schueneman, Robert J. MoonKeywordsSourceUSDA Forest Service General Technical ReportYear2022
- Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major vegetation productivity component: woody biomass growth. Here we compile a pantropical tree-ring network to show that annual woody biomass growth increases primarily with dry-season...AuthorsShankar Panthi, Gonzalo Pérez-De-Lis, Darwin Pucha-Cofrep, Nathsuda Pumijumnong, Mizanur Rahman, Jorge Andres Ramirez, Edilson Jimmy Requena-Rojas, Adauto de Souza Ribeiro, Iain Robertson, Fidel Alejandro Roig, Ernesto Alonso Rubio-Camacho, Ute Sass-Klaassen, Jochen Schöngart, Paul R.

- The impact of pyrolysis gas composition and the underlying reaction kinetics on the burning characteristics of a leaf was computationally investigated. The computational configuration resembled a previous experimental setup where vertically oriented manzanita (Arctostaphylos glandulosa) leaves were burned. Different compositions and reaction kinetics for the pyrolysis gas released during the leaf thermal decomposition were examined. The most detailed composition included CH4, CO, CO2, and H2, which was suggested by the previous experimental study of pyrolysis products of different plant...AuthorsPeyman Rahimi Borujerdi, Babak Shotorban, Shankar Mahalingam, David R.
