These guidelines are designed to facilitate robust integration of gender equality perspectives in the entire project cycle, from design to implementation to monitoring, evaluation and reporting in UNDP’s environment and sustainable development projects in Asia and the Pacific. Gender equality is a prerequisite for sustainable development. Only when women and men are equally empowered to manage the development processes are those developments likely to be sustainable, resilient and durable. To that end, these guidelines will assist UNDP staff to design better projects in the first place so that better results will be achieved.
