In this third decade of the 21st century, the environmental challenges we have ahead of us, set out in the UN's 2030 agenda for sustainable development, are many. Some of the major global environmental issues we need to resolve by 2030 are public health issues, soil and land pollution, water pollution etc. In view of this, we have been working on development of spectroscopic systems and methods to carry out fast, qualitative, and quantitative analysis of materials (solid/liquid/gas) located at distances of several tens of meters especially of samples, at not easily accessible locations, remotely. The complementary and layer-by-layer information gathered by a SINGLE spectroscopy system capable of two or more different spectroscopic analytical techniques in a “combinatory” approach is the need of the hour and will remove any ambiguities which may arise from the “single technique” approach, in identifying real complex samples in remote, In Situ, “As Is, Where Is” mode for environmental, mineralogical, industrial, space exploration, biomedical applications, etc. Major focus of our research is on the said line to meet such societal needs.
