In the wake of climate change, environmental degradation, and increasing global populations, food and water security are under threat throughout the world. This chapter focuses on the impacts of climate change on water security in Australia and Bangladesh, noting in particular the gendered implications and the way policies influence and shape gendered responses. In Bangladesh, for example, following disasters, access to safe, uncontaminated water may involve women walking significant distances. Australian research has examined the impact of water policies on gendered livelihood strategies as farming families readjust to their reduced access to irrigation water. A critical feature of this chapter is an examination of the way water has become “commodified” and reconfigured around new forms of market value. The chapter poses questions about the ongoing impact of water insecurity in the face of predicted and extreme climate events.
