This report seeks to provide a framework to measure the nexus between gender and the environment. It proposes 18 gender-environment indicators for inclusion in the wider set of gender indicators, across the focal areas of right to land, natural resources and biodiversity; access to food, energy, water and sanitation; climate change, sustainable production and consumption, and health; and women in environmental decision making at all levels. This report then presents enabling conditions at national level, including through action research conducted in three partner countries: Lao People’s Democratic Republic (Lao PDR), Kenya and Mexico. In addition to exploring lessons learned and challenges to closing data gaps, recommendations for building on best and promising practices comprise the final chapter, with main ideas geared toward national statistics systems as well as inter-agency UN expert groups.
