An estimated 5,000 sex workers and activists from across India and from more than 40 countries marched shoulder-to-shoulder through Kolkata. The march began in Sonagachi, or 'Golden Tree', in north Kolkata.

'Prohibition makes people invisible, harder to reach, harder to support. Sex work for me means independence and also freedom – I have time to care for my partner and do political work.' Ariane started in a brothel but now works independently. 'People who deny our self-determination and see us as victims deny our ability and the reality that we make a choice every day. This is abusive behaviour, really'Photograph: Dibyangshu Sarkar/AFP/Getty Images‘We're here to show our solidarity with others in India,’ says Geetha (not pictured), a sex worker from Karnataka, in south-west India. 'We also want to learn from the groups in West Bengal, which has a longer history of organising. We've been disadvantaged by so many things, socially, economically. And we’re deprived of many welfare schemes,’ says Geetha. She has struggled to get some form of national ID, without which she has no access to welfare programmesPhotograph: Piyal Adhikary/EPAA local sex worker watches the rally. Hundreds of multi-storey brothels line Sonagachi's narrow streets studded with small shops and entries to alleyways. The Kolkata sex trade is mainly brothel-based, operating out of different red light districts. An estimated 11,000 sex workers operate out of Sonagachi. Although most live in the area, roughly 3,000 travel to the district from their homes, working as 'floating' sex workersPhotograph: Piyal Adhikary/EPAA demonstrator holds a sign from the Durbar Mahila Samanwaya Committee (DMSC), a forum of 65,000 female, male and transgender sex workers in West Bengal. Founded in 1995, DMSC advocates for sex work to be recognised as work and for social and economic security for sex workers and their children.

The projects combine condom promotion and distribution with project management, targeted information campaigns, and efforts to improve the conditions of sex workers and tackle violence. The UN special envoy for HIV and Aids in the Asia-Pacific region said the Sonagachi project, run by DMSC, is one of the most successful HIV prevention efforts and provided a model for India's national Aids strategyPhotograph: Dibyangshu Sarkar/AFP/Getty Images'We are entertainers and we are labourers,' said Sapna Gayen (not pictured), from DMSC. 'We need our own trade unions.

Jaya, a sex workers' rights activist from Bangladesh, said sex workers fear a backlash from religious fundamentalists. 'During the month of Ramadan all the fundamentalists come together and in the name of religion threaten to evict us and deny us our rights'Photograph: Bikas Das/AP'When you’re doing it, of course you see it as work. It buys your food, pays for school,' says Daisy Nakato (not pictured), from Uganda. 'If it was decriminalised, if one could choose to be a sex worker, in a safe environment, I think it would be a good job. What make it bad work are the laws and policies' Photograph: Luca Stevenson/Sex Worker Open University Photograph: Luca Stevenson /Sex Worker Open UniversityIndian sex workers watch the march, which ended on College Street, where cramped colourful bookstalls take over the pavement, forming one of the largest second-hand book markets in the world.
