Since 1996, Taiwan has implemented a satellite monitoring project to effectively prevent illegal and improper land development. This project utilizes monthly satellite images for large-scale and multi-temporal monitoring of land-use changes. In 2022, the COVID-19 pandemic broke out in Taiwan on a large scale. During the pandemic, people's lives underwent significant changes, such as working and attending classes at home, reducing outdoor activities. Consequently, there were changes in land usage. For example, people chose slope areas with lower population density to live and relax. Therefore, this study explores the impact of the COVID-19 pandemic on land use in Taiwan's Slope areas before and after the outbreak.
The COVID-19 situation in Taiwan remained stable in 2021, followed by a large-scale outbreak in 2022, resulting in restricted social activities. By 2023, the pandemic began to subside, and people started returning to their normal lives. Firstly, the analysis of land use change detection data from 2021 to 2023 revealed that the number of reported change areas was 11,089 in 2021, 9,276 in 2022, and 10,848 in 2023. Furthermore, the data related to illegal areas shows 3,039 cases in 2021, 2,742 cases in 2022, and 3,043 cases in 2023.The data shows that, influenced by the COVID-19 pandemic, there is a shortage of labor and transportation restrictions, leading to a decrease in land usage and development. As a result, the reported change areas and illegal areas in 2022 are lower compared to both 2021 and 2023. After the pandemic began to subside in 2023, the influence of the pandemic diminished, and the number of reported change areas gradually returned to pre-pandemic levels.
In conclusion, the COVID-19 pandemic had short-term impacts on land use, changing people's lifestyles and subsequently affecting the demand and usage patterns of land. To effectively grasp land use changes, long-term and regular land use monitoring is necessary.
