Simulating impact of over-grazing on grassland degradation using GIS: a case study in the Heihe River Basin, China

This study has provided materials and curricula for disaster education in China and Japan. Most students show improved results. The ability of students to utilize electronic devices affects the learning of GIS-related content rather than other aspects. The frequency of daily usage of online maps and daily attention to disaster prevention affects learning the entire materials. This study can better understand the benefits and limitations of electronic maps in disaster education.
