Post Wildfire Vegetation Response To The Wildland-Urban Interface: A Case Study Of The Station Fire, Angelo C. De Guzman, Raju Bista, Parveen K. Chhetri

CSU Journal of Sustainability and Climate Change

In the past, wildfires served as a method for mother nature to promote biodiversity and to help maintain a functioning ecosystem. However, climate change alters the fire regime, significantly impacting vegetation recovery. Human disturbances and increased land use and land cover heighten vegetation disruption and abundance after a fire. Wildland-urban interface (WUI) – the region where the vegetation intermingles with the roads, houses, and human-made structures – threatens vegetation and the human population. Overall vegetation recovery after the Station Fire of 2009 spread through the San Gabriel Mountains, Los Angeles County was observed using Digital Elevation Model (DEM), Normalized Difference …

Climate change is posing significant challenges to California’s energy sector. Extreme weather events (heat and cold) may pressure existing infrastructure. Many studies have indicated that extreme climate events would impact the energy system by affecting peak electricity demand. However, very few studies have been conducted to understand how disadvantaged communities (DACs) will be impacted. Because of unequal access to energy infrastructure (electricity generation and battery storage), DACs are more vulnerable to power outages due to the rising number of significant weather events caused by climate change. To address the issue of how DACs are disproportionately affected by climate change-related energy …


Benefits Of Cover Cropping Systems In Walnut Orchards As Sustainable Agricultural Practice, Ana Medic, Consuelo B. Baez Vega Jan 2022

Benefits Of Cover Cropping Systems In Walnut Orchards As Sustainable Agricultural Practice, Ana Medic, Consuelo B. Baez Vega

CSU Journal of Sustainability and Climate Change

In recent years walnut orchards implemented cover crops in between rows to improve soil’s quality, lessen soil’s erosion, increase organic matter, manage nutrient movement and availability, enhance water retention, and expand microbe, insect, and flora diversity. Commonly selected cover crops in California are from families Poaceae, Brassicaceae, and Fabaceae. Considerations should be made when choosing a particular cover crop mixture to enhance multiple benefits and improve sustainable practices in orchard settings. An experiment was conducted in a walnut orchard to compare functionality and benefits of three systems multi-crop, monocrop, and no vegetation cover crop system. The following components were evaluated: …


A Closer Look At Csr Practices In Sustainable Fashion: A Guideline For Apparel Brands, Elline Deogracias, Tracie Tung, Natale Zappia Jan 2022

A Closer Look At Csr Practices In Sustainable Fashion: A Guideline For Apparel Brands, Elline Deogracias, Tracie Tung, Natale Zappia

While it might be greenwashing that impedes consumers' eco-consumption, the researchers posit that this gap is also due to fashion brands’ weak CSR communication and inconsistent understanding of CSR activities. This study aims to 1) determine the ease with which consumers can navigate sustainable fashion brand websites to find corporate social responsibility (CSR) activities, and 2) construct a framework that clearly identifies CSR activities, CSR dimensions, and the business operation stages at which they occur. Website content analyses were conducted on 27 sustainable fashion brands in the United States to investigate their CSR activities. A framework was proposed to better …
