United Nations Institute for Water, Environment and Health (UNU-INWEH)

Oluwabusola Olaniyan's placement was with the United Nations Institute for Water, Environment and Health (UNU-INWEH), an organisation that acts as the “United Nations’ Think Tank on water”. She worked as a secondary researcher to determine the world municipal wastewater volume by collecting national level data for almost all countries from published and web-based reports and sources.

The research involved data collection, mining, organization; management, synthesis and statistical analysis using excel spreadsheet and the Statistical Package for the Social Sciences (SPSS). Statistical analysis of the global municipal wastewater result derives a range of projections into the year 2050 while the study's overview highlights insights, taking the research beyond pure facts. The research outcomes are applicable to respond directly to regional and global water crisis that facilitate efforts to meet UN Development goals. Overarching result supports evidence informed decision-making and the post 2015 framework for sustainable development. It is also an input to a journal paper on wastewater. Significantly, the research is timely towards the global vision and post 2015 agenda because its approach is based on policy-practice-research.
