As of 2015, with the adoption of the Sustainable Development Goals (SDGs), the United Nations has a new roadmap for development that will guide global and national agendas for the next 15 years. Mental health was explicitly included in the SDGs, for the first time being recognised as an essential component of development. This is a major achievement that has taken decades of unrelenting advocacy. Still, mental health lacks clear, measurable indicators within the SDGs, threatening its progress in the realm of global development. The task now is for the global mental health community to actively work within health systems, and with other sectors, to integrate mental health interventions and indicators into programmes aimed at other goals and targets. In this way, the direct impact of mental health on development and the impact of mental health on other development goals will be recognised and quantified.
