Our Earth's system is experiencing unprecedented environmental changes, such as climate and land-use changes, biodiversity loss, biological invasions, and population growth. These changes present significant challenges to the sustainability of ecosystem goods and services that support prospering human society. The Qiu lab is investigating how global environmental changes and their interactions alter human-dominated landscapes at regional to global scales, and consequences for biotic communities and a range of vital ecosystem services. In particular, we are interested in exploring the dynamics and interactions of terrestrial (food and biofuel production, climate regulation, soil retention, timber product, recreation) and freshwater services (freshwater supply, surface- and ground-water quality, flood regulation) from both contemporary and future perspectives. Our research takes an interdisciplinary approach integrating geospatial analysis, biophysical and computational modeling, artificial intelligence, landscape and remote sensing, field observation and experiment, data synthesis, and social sciences to address basic and applied research questions across a range of spatial and temporal scales. Our research is critical for improved management of our landscapes and developing innovative solutions to ensure human wellbeing while maintaining the life-support systems of the planet in a changing and uncertain future.
