This document identifies the global water cycle as an integral part of the Earth/climate system and explores the interconnectedness between climate, the hydrological cycle and the Sustainable Development Goals. Within 'Transforming our World: the 2030 Agenda for Sustainable Development' it clearly states that climate change is a major challenge, which could potentially undermine all sustainable development: “Understanding that climate change is one of the greatest challenges of our time and its adverse impacts undermine the ability of all countries to achieve sustainable development." This indicates that addressing the causes of human-induced climate change is critical for the realisation of sustainable development and that it is essential to include this, in order to identify the interactions between the Sustainable Development Goals and their Targets.
