This week, David Cameron sets off to Liberia's capital, Monrovia, for influential UN talks on what should replace the Millennium Development Goals (MDGs) when they expire in 2015.

Across the world, 1 in 3 women risk shame, disease, harassment and even attack because they have nowhere safe to go to the toilet. That's 1.25 billion women - daughters, sisters, mothers, grandmothers. Facing each day without access to this basic necessity is not just an inconvenience; it impacts on all aspects of life, and it is women and girls who suffer the most. Having nowhere safe to go to the toilet also means an increased risk of shame, harassment and even violence for women and girls when they are forced to go out in search of a private place to go to the toilet.
The key theme at this year's Stockholm World Water Week is water and food security: how do we meet the ever developing needs of a growing population with an increasing demand for resources?
But this World Toilet Day (19 November), there are 2.6 billion people across the world who have nowhere safe to go to the toilet. That's two out of five people for whom a toilet is an unimaginable luxury. Meanwhile, almost 900 million people are forced to risk their lives on a daily basis by drinking dirty water because they have no other option.
