The charity wants to raise awareness of the fact that women's rights are often not upheld in developing countries. These include the right to equal pay with men, protection from violence and equal access to education and healthcare.
ActionAid will use International Women's Day on 8 March as a campaign hook.
Acting PR manager Wendy Bailey said the charity had a raft of activity planned, including a hard-hitting photo exhibition at London's City Hall.
‘As well as reaching out to current supporters, we hope publicity surrounding these events will help us reach new audiences,' added Bailey.
‘It is estimated that although women account for two-thirds of the world's working hours, they receive a tenth of the income,' she said.
The exhibition, called Face the Truth, will showcase photography accompanied by ‘graphic text detailing the harsh reality of poverty and inequality'.
It will also feature images of poor women superimposed onto a photo of City Hall's café.
The charity has also organised a 9 March debate. Speakers will include the International Development Secretary Hilary Benn.
