2016 Research & Development Programme


NBRO Research and Development (R & D) programme was rejuvenated in 2013 with the General Treasury restoring provision of their annual research grant to NBRO. This programme was continued successfully from the year 2014 to 2016. In the year of 2016, various studies were conducted under the broader theme of "Risk Awareness and Future Challenges".

NBRO received a research grant in 2017 to continue its research and development programme. Research proposals from NBRO scientists for 2017 comprise of many new proposals and several proposals to continue the research work of previous years.
