Challenges that ECOWAS has faced in its operation:a) Political instability in member states. Countries like Nigeria and Ghana have witnessed Military coups. Civil wars have been fought in Sierra Leone, Liberia and Ivory Coast.b) Nationalistic issues. Most member states give priority to their own domestic issues at the expense of the organization.c) Language barrier. Countries in West Africa inherited the languages of their former colonial masters.d) Infrastructural problems. The state of roads, railway and communication linkages are poor. This has hampered economic progress of member states. e) Ideological differences. The leaders of the member states view each other with suspicion and mistrust due to differences in ideologies.
