Economic valuation of forest benefits for drinking water is complex in part because the potential economic benefit is indirectly related to forest preservation through the benefit of forests for water quality. We contribute to a growing literature on land use water quality interactions by linking ecological production and economic valuation functions that relate to changes in forest cover and water...AuthorsArpita Nehra, Justin S.

- Estimating the biomass of terrestrial forests generally, and mangrove forests in particular, is an area of considerable interest. Most approaches rely on empirically derived allometric models to predict tree biomass. The single parameter with the strongest predictive ability in most studies is diameter at breast height (DBH); however the use of DBH arose primarily out of convenience, not from an analysis of tree form. While DBH explains a lot of variability in other tree metrics such as height or above ground biomass, its utility in smaller species is uncertain. Here we used measurements...AuthorsCharles A.

- In forested, seasonally dry watersheds, winter rains commonly replenish water storage deficits in the vadose zone before recharging underlying hillslope groundwater systems that sustain streamflow. However, the relative inaccessibility of the subsurface limits our understanding of how groundwater recharge is moderated by vadose zone storage deficits generated by plant-water uptake. Here, we compare groundwater recharge inferred from the storage-discharge relationship with independent, distributed estimates of deficits across 12 undisturbed California watersheds. We find accrued dry season...AuthorsNoah K. Benitez‐Nelson, David Dralle, W. Jesse Hahm, Daniella M. RempeSourceWater Resources ResearchYear2025
- Structural insulated panel foams are made primarily from petrochemicals. As a biopolymer, lignin is a promising raw material substitute for foam production. Nondestructive evaluation is routinely used for structural material strength and stiffness assessment. Herein, mechanical acoustic velocity (AV) was used to nondestructively evaluate lignin-foam blocks. Overall, foam block weight was determined, and flying time was measured for various foam thicknesses ranging from 7.26 to 8.89 cm (3.0 to 3.5 in.). Additionally, for each block, AV was measured at several different positions/locations....AuthorsSeyed Abolghasem Fatemi, Rubin Shmulsky, Zhiyong Cai, Qiangu Yan, Zach KyzerSourceForest Products JournalYear2025
- Polyurethane foam is a valuable material with applications across the automotive, packaging, construction, appliance, and furniture industries. However, traditional polyurethane foams are made from petroleumbased precursors including harmful isocyanates. Isocyanates are the leading cause of workplace asthma and are made from toxic phosgene gas, representing a challenge to green chemistry principles. To address these concerns, non-isocyanate polyurethane (NIPU) foams replace the traditional polyurethane reaction with a safer, non-isocyanate process most often employing cyclic carbonates and...AuthorsKathryn Evancho, Richard Reiner, Biljana Bujanovic, Srikanth Pilla, James SternbergKeywordsSourceRSC AdvancesYear2025
- Transient conditions arising from sun exposure of absorptive claddings after being wetted by rain impose significant hygrothermal load on wood-frame walls. In this paper, we show that moisture conditions generated by the inward drive of water vapor increase the risk of mold growth and durability issues in susceptible components of the wall assembly. We present a comprehensive set of one-dimensional hygrothermal simulations on solar-driven moisture diffusion in wood-frame walls with brick cladding and oriented strand board (OSB) sheathing. Sensitivity analysis identifies key material...AuthorsNatalia Farkas, Samuel V. Glass, Samuel L. ZelinkaSourcepaper in proceedingsYear2025
- This study investigates the role of Forest Stewardship Council (FSC) certification in advancing sustainable forest management and influencing forest cover changes across 70 countries from 2000 to 2021. Using dynamic panel data model and Generalized Method of Moments (GMM) estimations, the analysis addresses endogeneity concerns, such as those stemming from lagged dependent variables, providing robust and unbiased estimates. Results indicate that FSC certification significantly enhances forest cover, with the most pronounced effects observed in low- and middle-income countries. Additionally,...AuthorsInoussa Boubacar, Yaya SissokoSourceJournal of Cleaner ProductionYear2025
Comparative Evaluation of the VTT Mold Index Model and the DR SIM Model for Moisture Risk Assessment
Hygrothermal simulations are useful in forensic investigations of moisture problems and in design analysis for identifying and mitigating potential risks both in new construction and retrofit of existing buildings. Damage models, including mold growth models, are often used as a means of assessing risk; such models use simulation outputs such as temperature and relative humidity or moisture content. The Finnish mold growth model (or VTT mold index model), a pioneering model used widely by researchers and practitioners, was developed based on laboratory data for a wide range of materials,...AuthorsSamuel V. Glass, Robert Lepage, Natalia Farkas, Samuel L. ZelinkaKeywordsSourcepaper in proceedingsYear2025- Many studies that use an automated sorption balance to determine a water vapor sorption isotherm for wood collect data until the moisture content change is less than or equal to 0.002% min−1 (20 μg g−1 min−1). This stop criterion has been claimed to give errors in equilibrium moisture content (EMC) predictions of less than 0.001 g g−1 but over the past 10 years, studies have shown that the actual errors can be greater than 0.01 g g−1 because the measurements are stopped well before equilibrium is reached. Despite the large errors associated with this stop criterion, it remains popular due...AuthorsSamuel L. Zelinka, Samuel V. Glass, Natalia Farkas, Emil E.

- Nearly 86% of forestlands in the Southern United States are owned by private forest landowners, and about twothirds of this area is owned by Family Forest Owners (FFOs). Forest legacy planning is crucial for ensuring the long-term sustainability of these forests. It includes formal aspects, such as estate planning, and informal aspects, such as discussions with the next generation about forest management plans. This study examines the factors that influence landowners’ estate planning decisions. We evaluate how landowners’ characteristics, behaviors, and motivations influence their estate...AuthorsAna Cubas-Baez, Rajan Parajuli, Erin O Sills, Frederick W Cubbage, Gregory E.
