Animating this book is a twofold question: In what ways are adult and popular educators responding to various harsh economic, political, cultural and environmental conditions? In doing so, are they planting seeds of hope for and imaginings of alternative futures which can connect individuals and communities locally and globally to achieve economic, ecological and social justice?The book illustrates how transformative politics of solidarity often involve actors across vastly different backgrounds. Solidarity is therefore a political relationship that is forged through particular struggles situated in place and time across power differentials. The authors put popular education to work by describing and analysing their strategies and approaches. They do so using accessible language and engaging styles.Popular education is a medium for dreaming, for imagining other futures. It is also essential for countering the wilful spreading of fake news and propagation of ignorance. Pedagogies of solidarity are necessary to building connections amongst people at a time when competitive individualism and alienation are rampant. Forging solidarity with and amongst communities is a means towards that end, and, indeed, an end in itself.
