At World Water Week in Stockholm, Sweden, IWMI researchers will weigh in on global water issues, contributing to several sessions focused on the 2017 theme Water and waste – reduce and reuse. The Institute figures as a key collaborating partner in this year’s event, which is organized by the Stockholm International Water Institute (SIWI). It provides an opportunity for scientists, policy makers and representatives of the private sector and civil society to foster new thinking and collaborative action on today’s most pressing water-related challenges.
