Is gender equality a sustainability issue?

UNEP’s Global Gender and Environment Outlook 2016 (GGEO) identified gender inequality as one of the main challenges to advance the environmental dimension of sustainable development, as it has negative impacts on access, use and control of natural resources, as well as the right to a clean, safe and healthy environment …

Women are active agents of conservation and restoration. In fact, evidence reveals that there is a correlation between environment and gender; when gender inequality is high, forest depletion, air pollution and other measures of environmental degradation are also high.

Why does Mexico City flood so easily?

A large majority of the city’s water supply comes from an underground aquifer that is being drained at a rate faster than it can refill. The ground is covered with concrete, which means that when it rains, rather than seep through the soil and return to the aquifer, the rainwater runs off.
