Colonial power has (dis)ordered the world as we know and live in it, as well as our prevailing notions of “modernity,” “development,” and even existence. Amidst this reality, youth voices on present-day climate and health crises are going unheard. Indeed, the disavowal of the political agency, aspirations, and dreams of young people regarding the co-creation of socially-just and environmentally-sustainable futures remains a persistent issue of exclusion. Moreover, the insights young people have about correcting enduring historical injustices and ideas they hold about living well in the Anthropocene continue to be dismissed in policy and scholarship. This is especially the case for youth from negatively racialised and marginalised communities in the Majority World/Global South. As a response and via “desire-based” methods developed with co-researchers in the Caribbean, this participatory project will expand knowledge on youth futures by unsettling liberal-Eurocentric conceptions of wellness, sustainability, and “global health” with Indigenous and Afrodescendant youth.
