Globally, forests have been cut, reducing carbon dioxide absorption and biodiversity. Land use practices have led to land degradation and desertification, as have droughts, including those linked to climate change.

As stewards of the land women must have access to land, livelihoods and natural resources, and a say in how they are shared. Women, and indigenous women in particular, need to be included in decision-making on ecosystem use at all levels, as essential players in preserving our planet.
