Trade networks for agricultural products play an important role in agricultural development and regional integration in West Africa. However, mapping these networks is challenging due to the lack of a comprehensive analytical framework that supports evidence-based policymaking. This policy note represents a first attempt to integrate the spatial, social and temporal aspects that influence trade […]

This study examines the long-term variation of the annual occurrence frequency for the Persistent Hot spell Events (PHEs) over the African continent and the underlying mechanisms using the Japanese 55-year Reanalysis (JRA-55) daily dataset for the period 1961–2021. We applied criterion for periods when the daily standardized anomaly index (SAI) value of mean daily temperature […]

The demand for renewable energy is becoming increasingly apparent, but a significant challenge lies in the limited availability of land. To limit environmental impacts associated with new development in previously undisturbed lands, this study investigates the potential to convert abandoned mines in Florida and Pennsylvania into solar farms, aligning with federal and state-level clean energy […]

Hurricane Ian, a Category 4 storm that struck Florida’s southwest coast, resulted in 156 fatalities, with two-thirds of the victims being seniors. This highlights the need to address disaster risks for this vulnerable population. This study utilizes anonymized and privacy enhanced mobile phone GPS data to examine mobility disruptions and recovery patterns during Hurricane Ian […]
Understanding the impacts of the COVID-19 pandemic on domestic migration patterns is crucial for addressing resource needs and migration forecasting. Only a limited number of studies, however, have explored these dynamics through the lens of network analysis. Using Internal Revenue Service (IRS) county-to-county migration data, this article conceptualizes the U.S. domestic migration system as complex […]

How do brands interact? Commercial brands are increasingly interconnected, forming a complex network. Analyzing brand networks is crucial to understanding brand interactions and developing data-driven marketing strategies. Traditional methods utilize consumer behavior surveys and social media databases to construct brand networks, but few have considered consumers’ spatial mobility – their movements between brand points of […]
