1. RESEARCH GOALS
Climate change and land use/land cover change have resulted in myriad environmental and socioeconomic problems, including prolonged droughts, decreased biodiversity and ecosystem services, and increased risks for disasters. To achieve regional and global sustainability, therefore, it is imperative to develop a mechanistic understanding of the processes and consequences of these global changes, and to produce actionable knowledge for policy making. The essence of the “Orderly Human Activities” (OHA) concept is to ensure sustainable development by actively adapting to climate change via human-land systems design and concerted efforts by scientists, governments, and stakeholders. Inspired by the OHA concept, our project aims to understand the relationship among climate change, ecosystem services, and human well-being, and to explore land systems-based strategies for advancing sustainable development in the Agro-Pastoral Transitional Zone in Northern China (APTZNC) under climate change.
Our research methodology integrates field observations, remote sensing, and simulation modeling. Several key research questions will be addressed through scenario analysis using spatially realistic coupled human-environment systems models. The outcome of the project is expected to help advance the science and application of landscape sustainability science, particularly in terms of linking climate change, ecosystem services, and human well-being.
The principal participating institutions of the project include Beijing Normal University, Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS), Institute of Botany of CAS, Institute of Geographic Sciences and Natural Resources Research of CAS, and Beijing Forestry University.
2. KEY RESEARCH QUESTIONS
(1) What is the relationship between climate change and human activities on landscape and regional scales?
Based on the OHA concept, we will examine how different human activities interact with climate change in the APTZNC. Different climate change scenarios, vis-à-vis land use and institutional changes, will be examined through simulation experiments using regional climate models that are linked with land systems models.
(2) What is the relationship between ecosystem services and human well-being under climate change across the APTZNC?
Understanding the interrelation between ecosystem services and human well-being is essential to enhance regional sustainability. We will investigate how climate change and land use change together influence ecosystem services and, consequently, human well-being on multiple scales, ranging from the local site to the landscape and the entire region. Indicators of key ecosystem services and major human well-being attributes will be identified, and their quantitative relationships will be established through dynamic modeling and statistical analysis.
(3) How can land systems in the APTZNC be spatially optimized to maintain and improve long-term ecosystem services and human well-being in the face of climate change and socioeconomic changes?
This research question builds on the first two, and will be addressed through dynamic model-based scenario analysis that simultaneously considers climate change, land use change, ecosystem services, human well-being, and socioeconomic and policy actions. To conduct the scenario analysis, existing and new models of climate change, land use change, and ecosystem services will be coupled in a hierarchical patch dynamic framework, and empirical field-based observations and case studies will be integrated with modeling. Intensive studies in representative sites selected from urban, agricultural, and pastoral areas will be combined with extensive studies on broad scales through a hierarchical “scaling ladder” approach. Different scenarios of both climate change and land systems design will be explored and evaluated.
3. OVERALL PROJECT DESIGN
