If you have any doubt as to why we think the UK's Department for International Development should prioritise disability, look no further than the situation of Esther Cheelo.

A spate of brutal attacks on young women in India's urban centres, most recently a young woman in Calcutta who died after being gang-raped and set on fire, have drawn world attention.

Imagine you need to use the loo. Really, right now, you desperately need a loo. Now imagine you're in Uganda, one of the poorest countries on the planet.

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.
