If you haven't been able to attend the recent EADI/ISS conference "Solidarity, Peace and Social Justice", it's worth watching the recordings of the plenary sessions:
The opening plenary "Global Solidarity & COVID-19" discusses how the Covid pandemic affected global solidarity, and how the practice of solidarity has changed our view on global transformations.
In the second plenary "Questioning Development – Towards Solidarity, Decoloniality, Conviviality", panellists discuss their perspectives and approaches to decolonising development (studies), focusing specifically on how new forms of solidarity and conviviality can be promoted and sustained to achieve global social justice.
