Dadansoddi sut y mae polisïau a chyllidebau cysylltiedig yn effeithio ar y gwahanol rywiau yw cyllidebu ar sail rhyw. Nid yw'n golygu gwahanol gyllidebau i fenywod a dynion. Yn hytrach, mae'n golygu mynd ati i nodi effaith gwariant ar gydraddoldeb rhwng y rhywiau, gan arwain at benderfyniadau cyllid sydd wedi’u targedu’n well ac, yn eu tro, at ganlyniadau gwell hefyd.
Gender budgeting is an analysis of how policies and associated budgets impact different genders. The approach does not mean different budgets for women and men. Instead, it involves actively identifying the impacts of spending on gender equality, leading to better focused funding decisions and in turn better outcomes.
