Professional experience

With a coupled human–environment system (HES) perspective, for years my research has focused on the development and application of multi-agent system (MAS) models to investigate land-use (including livelihoods) systems' transitions in relation to ecosystem services, food security and regional/global change drivers. The aim is to develop HES-based tools to support the transdisciplinary identification of critical leverage points for effective interventions and pathways of community-landscape transition towards improved food productivity/profitability, ecosystem services and social equity. I have researched into the analysis and simulation of adaptive land-use decisions, integration of ecological models into MAS models of social–ecological systems, and the feedbacks of long-term trends in land degradation or development into nature–society relationships. Recently, my research interests have extended to an understanding of factors and mechanisms accounting for vulnerability and resilience of rural landscape systems in the face of global changes and viable social–ecological mechanisms for effective restoration of degraded lands. I am also conducting regional, continental and global assessment of land degradation and improvement (including restoration). In these large-scale works the HES perspective is still hold but the foci are rather spatio-temporally explicit assessment of land degradation/improvement and the identification of related social-ecological domains. The later work involves the delineation of spatial clusters of boundary setting factors/potential drivers of land degradation/improvement across the globe. These clusters will serve as matrices for selecting spectra of representative case areas for process-based HES studies, and as spatial strata for generalization of site-specific knowledge generated. Depending on concrete research aspects, my geographic focus includes selected developing countries in Sub-Saharan Africa (SSA), Southeast Asia (SEA) and sub-continental/large region whole (SSA, SEA, global dryland) and whole globe.
