How can we measure the impact on the status of women of the Beijing and Dakar Platforms for Action in African countries ten years after the Platforms were established? This manual aims to give clear guidance to gender impact assessment evaluators on how to carry out such monitoring. It provides direction on conducting impact evaluation exercises, including what data to collect; how to analyse and interpret the data; and how to report the findings. Five key areas form the focus of the guide: food security, health, trade and industry, planning, and finance. Areas indicative of progress are listed for each. In the case of food security, for example, the areas are: increased access to productive resources by women - including markets; increased productivity/production; increased incomes; fair sharing of household chores; and access to benefits and services from government. For each area of change, quantitative and qualitative indicators are listed. For example, for access to productive resources and services, quantitative indicators include: landholding size (in hectares) and tenure (by sex, age, marital status, residence) and the amount of time women/men devote to activities within and outside the home (market and non-market activities). An example of qualitative indicators is perceptions of women and men regarding adequacy and equitable accessibility to productive resources (including markets) for women versus men.
