Gender profile of climate-smart agriculture in Ghana por CGIAR Research Program on Climate Change, Agriculture and Food Security

“…For CSA interventions to be more effective and sustainable, it must be designed to address gender inequalities and discrimination against vulnerable and marginalized groups. While countries are now taking advantage of synthesized countryspecific knowledge on CSA through the country CSA profiles (e.g.: CCAFS profiles, https://ccafs.cgiar.org/resources/publications/csa-country-profiles), integrating gender in CSA projects design and implementation is identified as imperative to reducing gender inequalities and enhancing an equal access to and the benefits from agricultural interventions (WB, FAO and IFAD, 2015). …”
