For a more comprehensive understanding of gender equality issues, the root causes of gender inequalities need to be examined: that is, socially constructed roles and responsibilities that have resulted in centuries of domination by "masculinist" attitudes and perceptions, definitions of problems, and setting of norms and values (thereby defining deviations from the norms). However, in all of the assessed environmental areas, there are very limited environment-related gender-disaggregated data that can show direct links between gender inequality and environmental changes. Gender-disaggregated data, where available, are often fragmented at the level of a country or group of countries, making it almost impossible to aggregate and compare some issues among different regions.
