But public work programmes need to be supplemented with targeted support to those that cannot work for various reasons, because they are physically incapacitated, including those with poor nutritional status, or because they are occupied with other valuable activities, such as attending school (Ravallion 2009). Finally, in order to stimulate female participation in the labour market, programmes need to be supplemented with affordable child care, kindergarten and pre-school services. However, the new evidence presented in these papers and reports is minimal. This can be explained by the lag with which new micro-data becomes available. Regular household budget surveys may not be sufficient to capture the impact of a crisis at household level and could be complemented with quick assessment surveys covering a smaller sample and qualitative survey instruments to capture the experience of households and individuals. There is clearly a need for timely and systematic data collection and more systematic assessments of poverty and vulnerabilities.
