Key Competencies

  1. Research interests are in soils, hydrology, landscape processes and nutrient dynamics on multi-scale environmental, hydro-pedology, spatiotemporal variations of land degradation, agronomic, ecological, and agroecosystem sciences. My research activities employ biometrics, GIS & remote sensing, modelling, and spatial statistical applications to mitigate land degradation, judicious resource use and efficiency, enhanced natural resource conservation and sustainability, and global food security.
