Yet, it is essential to ensure clear and powerful mandates, sufficient resources and political leadership for these institutions to place gender considerations effectively at the top of the policy agenda. About half of OECD countries also deal with gender issues as part of the broader portfolios in ministries (e.g. the Czech Republic, Finland, Germany, Greece, Ireland, Norway, the Slovak Republic, Spain, Sweden and Switzerland). In Algeria, an administratively centralised main gender institution co-ordinates with geographically decentralised sections. At the local level, social section bureaus exist in every wilaya (province) in Algeria for the purpose of enhancing the situation of families and women.
