Northern Ireland’s post-accord peacebuilding includes a ‘big industry’ that took off after the signing of the 1998 Belfast or Good Friday Agreement (GFA). This peace infrastructure has been largely sustained by the financial contributions of the external guarantors of the peace process, including the British and Irish governments as well as the European Union (E.U.) Peace and Reconciliation Program and the International Fund for Ireland (IFI). E.U. and IFI funding have de-escalated the intense political violence and set the scene for local grassroots reconciliation and rehabilitation projects in Northern Ireland and the Republic of Ireland’s Border Counties. Consequently, this chapter focuses on the efficacy of Civil Society Organizations’ (CSOs) programs and other grassroots mobilizers utilizing the E.U. and IFI funding to seek more desegregated avenues to build sustainable and ethical peace in Northern Ireland and the Border Counties. Drawing on the CSOs experiences and perceptions of local politics and funding practices of designated peacebuilding programs, the chapter finds that economic resources can bolster local peacebuilding efforts in immeasurable ways through the reconstruction of collapsed infrastructures, establishing vocational centers, facilitating problem-solving workshops, CSO training, and the reintegration of ex-combatants. However, insulating the conflict’s primary actors and beneficiaries of the peace programs poses some disruptive consequences both in the immediate and long term.
