For example, transfers to poor households with children are generally targeted according to level of income, but evidence shows that - despite their positive impact on poverty - transfers have been affected by large errors of inclusion/exclusion, as in the case of allowances in Eastern European countries, or by other inefficiencies linked to the high costs of targeting, evident in the South African child grants (European Report on Development, 2010). In the case of school feeding, for instance, we observed that combining the means of providing meals (on-site, take-home), as in the case of Cambodia, has achieved multiple objectives in terms of a household's decision to send their children to school and to keep their attendance rates high. On the other hand, programmes combining measures that foster access with supply side interventions that provide structures and services to poor children, has proven relevant in supporting their participation in school, such as BRAC in Bangladesh and BRIGFIT in Burkina Faso, while the milk supply programme in Mexico contributes to improving nutrition standards.
