Land use effects of biofuel production in the US
(JOURNAL) [Published : May 12, 2023]
Biodiesel production from soybean has been growing in the United States and although its amount is small by comparison with corn ethanol, its addition to existing demands on land can have nonlinear effects on land use, due to an upward sloping and increasingly inelastic supply of...

Global change scenarios in coastal deltas and their sustainable development implications
(JOURNAL) [Published : Sep 01, 2023]
Deltas play a critical role in the ambition to achieve global sustainable development given their relatively large shares in population and productive croplands, as well as their precarious low-lying position between upstream river basin development and rising seas. The large pre...
Projection of Sediment Loading from Pearl River Basin, Mississippi into Gulf of Mexico under a Future Climate with Afforestation
(JOURNAL) [Published : May 17, 2023]
Sediment load in rivers is recognized as both a carrier and a potential source of contaminants. Sediment deposition significantly changes river flow and morphology, thereby affecting stream hydrology and aquatic life. We projected sediment load from the Pearl River basin (PRB), M...
A temperature binning approach for multi-sector climate impact analysis
(JOURNAL) [Published : Mar 19, 2021]
Characterizing the future risks of climate change is a key goal of climate impacts analysis. Temperature binning provides a framework for analyzing sector-specific impacts by degree of warming as an alternative or complement to traditional scenario-based approaches in order to im...
Marginal Damage of Methane Emissions: Ozone Impacts on Agriculture
(JOURNAL) [Published : Feb 21, 2023]
Methane directly contributes to air pollution, as an ozone precursor, and to climate change, generating physical and economic damages to different systems, namely agriculture, vegetation, energy, human health, or biodiversity. The methane-related damages to climate, measured as t...
Economic valuation of coccidioidomycosis (Valley fever) projections in the United States in response to climate change
(JOURNAL) [Published : Jan 01, 2021]
Coccidioidomycosis, or valley fever, is an infectious fungal disease currently endemic to the southwestern United States. Symptoms of valley fever range in severity from flu-like illness to severe morbidity and mortality. Warming temperatures and changes in precipitation patterns...
A generic scenario analysis of end-of-life plastic management: Chemical additives
(JOURNAL) [Published : Jan 05, 2023]
Plastic growing demand and the increment in global plastics production have raised the number of spent plastics, out of which over 90% are either landfilled or incinerated. Both methods for handling spent plastics are susceptible to releasing toxic substances, damaging air, water...
Causal Bayesian networks in assessments of wildfire risks: Opportunities for ecological risk assessment and management
(JOURNAL) [Published : Nov 01, 2021]
Wildfire risks and losses have increased over the last 100 years, associated with population expansion, land use and management practices, and global climate change, with more than 30% of the global land surface experiencing significant fire frequency. While there have been exten...
