Ranjeet's research interests focus on the applications of Remote Sensing and Geospatial technologies to study biophysical attributes that include carbon, water & energy fluxes at varying scales in context of ecosystem ecology, land cover/land use, and climate change. His current position in the LEES lab requires him to synthesize existing meteorological and medium to coarse resolution satellite derived-data (for e.g., drought indices, extreme climate anomalies & non-parametric trend analysis). In addition, his research also involves scaling up from in situ observations from various eddy covariance flux towers and standard ground truth methods to a regional scale in context of rapid climatic and socio-economic changes (in the Mongolian Plateau and elsewhere).

Research

These studies aim to examine and model the changes of the natural and human systems on the Mongolian Plateau as well as the critical feedbacks between them over recent decades.

Hypotheses: While climate change has created pressure on ecosystems and societies in the Plateau, the distinct socioeconomic conditions and development paths of the different administrative units involved have also had a significant effect on the relationships and feedbacks within the human and natural systems. Also, human influences on the systems exceeded those of the biophysical changes but the significance varies in time, location, and ecological setting.
