HWISE collaborations, which have grown organically around ad-hoc workshops (funded by our respective institutions and institutes) and sponsored projects, now include over 40 scholars from 24 U.S. and international institutions across the career spectrum (post-doctoral researchers and early career scholars to middle and advanced researchers) and social science disciplines.  In short, our effort to date is only the beginning of a productive research collaborative network to advance conceptual and methodological frontiers in water security and environmental social science.
