The IAHR Working Group on the Sustainable Development Goals (SDGs) aims at coordinating IAHR’s activities in support of the global efforts to achieve the SDGs by 2030. For this purpose, it collaborates with several IAHR Technical Committees. Besides SDG 6 which aims at ensuring the availability and sustainable management of water and sanitation for all, the effort to achieve several other SDGs can benefit from the experience and knowledge of IAHR members on the hydraulics of engineered structures and natural systems, especially on matters pertaining to their environmental protection and sustainable management. Goals that directly or indirectly affected by or depend on water include ending poverty in all its forms (SDG 1); eliminating hunger and providing food security (SDG 2); ensuring good health and well-being for all (SDG 3); affordable, reliable, sustainable and clean energy (SDG 7); safe, resilient and sustainable cities (SDG 11); sustainable consumption and production (SDG 12); climate change (SDG 13); and biodiversity, forests, deforestation (SDG 15).
