Prima Jesusa Quinsayas: Quinsayas has worked as a private prosecutor in the most notorious cases of media killings in the Philippines, including on behalf of the witnesses and families of the journalists killed in the 2009 Ampatuan massacre.
With law enforcement agencies failing to properly investigate media killings, Quinsayas has to find eyewitnesses herself. "To do so, I have to go to places where women are considered second-class citizens who are seen rather than heard, or, worse, are viewed as sex objects. If I sound like an aggressive lawyer, a no-no for a woman, [the witnesses] will be hostile and will not be receptive no matter how rational my arguments may be."
Zainab Al-Khawaja: It's hard to keep track of how many times activist Al-Khawaja (@angryarabiya) has been in and out of jail. She is facing more than a dozen charges for speaking out about human rights violations in Bahrain – and was again detained before she had the chance to answer our questions.
But she asked her sister Maryam to pass this message on: "I'm confined within these four walls because I want to build a better future for my 3-year-old daughter. I want her to be able to live with rights, dignity and freedom without having to go through the struggle we are living."
Rayma Suprani: When a cartoon by Suprani highlighting Venezuela's poverty crisis was published last year, she received death threats from state-run media and supporters of President Hugo Chávez. The threats remain uninvestigated.
She says, "As women we are even more vulnerable. We, as women, mothers and daughters, single or married, must be allowed to act in roles of our own choosing, roles we desire – not the roles prescribed for us by our 'machista' ancestors from a regressive past."
Nguyen Hoang Vi: Nguyen has spent much of her early 20s under surveillance by security agents for blogging critically about the government. Shortly after we profiled her, she was detained near the courthouse where she was hoping to attend the appeal of three bloggers jailed on anti-state propaganda charges. While in custody, she was sexually assaulted by police and state nurses.
Speaking of her ordeal, Nguyen said, "We can't allow fear to paralyse us. We must find it deep within our hearts to forgive all that they're doing to us and to our bodies. Forgiveness is not the same as acceptance. We must let them know that what we are doing is not based on personal hatred of our perpetrators; it is to protect our universal rights, which belong to them as well as us."
Jineth Bedoya Lima: In 2000, when Bedoya was investigating alleged arms trafficking involving state officials and a paramilitary group, she was grabbed, drugged, raped and left bound in a garbage dump. Today, Bedoya is still reporting in Colombia, despite receiving threats regularly.
"Without a doubt, the greatest risk for us women is being attacked," she says. "Women should take the necessary precautions to avoid putting themselves at risk. And if there is an imminent threat, they must report it in a timely manner. Silence is what the perpetrators of violence feed on."
Iryna Khalip: In 2011, Khalip was given a two-year suspended sentence for her role in protests against President Alexander Lukashenko's December 2010 controversial re-election, and was banned from travelling and from moving or leaving Minsk. Officials also threatened to put her young son in state custody.
On International Women's Day, Khalip hopes for a world where "you are not afraid to love, to give birth, to go to sleep every night, to speak openly and fight injustice, to live in your country and raise your children in your country, to be a professional and to be a citizen; you are indeed not afraid to be a woman."
