This chapter centres on separate but related SDP initiatives, namely the cross-community project Football for Peace, which was founded in Israel in 2001, and the parallel programme Rugby for Peace formed in Colombia in 2019. As a pretext, the work firstly addresses the formation of Belfast United in Northern Ireland in 1991. This initiative applied Allport’s contact hypothesis in seeking to build cross-community relationships through a group of Protestants and Catholics in Northern Ireland during the Troubles. The chapter then examines the establishment of Football for Peace in Israel, with both programmes driven by Professor John Sugden. The work addresses the political context of Israel and Palestine, and the meaning, value and limitations of sport as a vehicle to build connections between Jews and Arabs in the fractured communities they inhabit. The research addresses the application of the Ripple Effect model, based on the insights of peace education theorist Gavriel Salomon. It explores the pedagogical approach developed and implemented by the University of Brighton, anchored in an innovative coaching manual featuring the core values of neutrality, inclusion, respect, trust and responsibility. The chapter explores the challenges associated with leading and assessing an SDP initiative through international student volunteer coaches, and local personnel as gatekeepers, translators and coaches. Addressing a model implemented across four continents, this extended chapter then charts the evolution and legacy of the project, adopted in other international contexts in South Korea, the Gambia and Colombia, with the latter adapted to rugby, as localised applications of global SDP.
