Civil society in Yemen is vibrant and diverse but highly fragmented. It includes independent registered and organized civic groups, less organized local self-help organizations, and charity oriented groups. The first period, from 1950 to 1963, saw a growth in associational activity in the modern enclave of late colonial Aden and within the protectorates of the northern imamate amidst heavy immigration and modernization. A second stage of development took place in the late 1970s and 1980s with very little central control but exceptional affluence thanks to remittances from citizens employed in the Gulf. As the political transition in Yemen continues, there is renewed interest in engaging local Civil Society Organizations (CSOs) in the process of service delivery, decentralization, institution building and in encouraging inclusion and greater citizen participation. The Government has requested that the World Bank update its earlier work on CSOs in Yemen to map and to assess the capacities of present-day, development-oriented CSOs in five governorates. Nearly all of the CSOs that participated in this study were formally registered, non-governmental organizations that were generally independent of tribal or religious affiliation. There is an important opening in Yemen at present to encourage greater social accountability among CSOs and through CSO-Government partnerships. Social accountability includes a growing emphasis on beneficiary engagement in monitoring and assessing government performance as well as service providers, particularly in providing feedback on, and voicing demand for, improved service delivery. Based on this study's findings, it is recommended that the Government reform CSOs-related procedures, including registration, re-licensing, and decentralize avenues for CSO-ministry collaboration on service delivery and standards development to the governorate-level branches of the respective Ministries. Finally, it is recommended that training be made available for Yemeni journalists that cover the work of the country's civic sector or development issues in general.
