Did you consider googleing this to see what she was referring to? Because I wasn’t sure either, but sure enough, a quick google search found:
The report, Gender and Climate Change(available here as a PDF), concludes that women are more severely affected by climate change and natural disasters because of their social roles and because of discrimination and poverty. To make matters worse, they’re also underrepresented in decision-making about climate change, greenhouse gas emissions, and, most critically, discussions and decisions about adaptation and mitigation. From the report:
For example, the 20,000 people who died in France during the extreme heat wave in Europe in 2003 included significantly more elderly women than men. In natural disasters that have occurred in recent years, both in developing and in developed countries, it is primarily the poor who have suffered—and all over the world, the majority of the poor are women, who at all levels earn less than men. In developing countries, women living in poverty bear a disproportionate burden of climate change consequences. Because of women’s marginalized status and dependence on local natural resources, their domestic burdens are increased, including additional work to fetch water, or to collect fuel and fodder. In some areas, climate change generates resource shortages and unreliable job markets, which lead to increased male-out migration and more women left behind with additional agricultural and households duties. Poor women’s lack of access to and control over natural resources, technologies and credit mean that they have fewer resources to cope with seasonal and episodic weather and natural disasters. Consequently traditional roles are reinforced, girls’ education suffers, and women’s ability to diversify their livelihoods (and therefore their capacity to access income-generating jobs) is diminished.
The report notes examples from other sources, including this:
An Oxfam Report (March 2005) on the impact of the 2004 Asia Tsunami on women raised alarms about gender imbalances since the majority of those killed and among those least able to recover were women. In Aceh, for example, more than 75 percent of those who died were women, resulting in a male-female ratio of 3:1 among the survivors. As so many mothers died, there have been major consequences with respect to infant mortality, early marriage of girls, neglect of girls’ education, sexual assault, trafficking in women and prostitution. These woes, however, are largely neglected in the media coverage.
In a study executed on behalf of ACTIONAID in 1993-1994 in the Himalayan region of Nepal, it became clear that environmental degradation has compounded stress within households and pressure on scarce resources. This meant that the pressure on children, particularly girl children, to do more work and at an earlier age was increasing. Girls do the hardiest work, have the least say and the fewest education options. Programmes that concentrate only on sending more girls to school were failing as the environmental and social conditions of the families deteriorated.
Amazing what a 5 second google search will teach you.
