The struggle to empower women; DAY 2: CHARITIES TACKLING BRUTAL REALITIES OF SLUM LIFE; Finding hope amid the horror of a city built on inequalities.
The skyscrapers etched on the Nairobi skyline boast of vast wealth and economic ambition but obscure a grim reality that lies far beneath the polished metal and mirrored windows.
There is plenty of money in the Kenyan capital, opulence that sits comfortably in one of the world's greatest capitals - nice cars, fancy restaurants and all the trappings of western materialism the select few can spend their fortunes on.
But this is a city where the gap between those who have so much and those who wake each morning wondering if their children will eat is profound.
The gleaming office blocks where some of the world's best known corporations do business and the slums where hundreds of thousands live define this cosmopolitan capital's staggering inequality.
Nowhere is this gap between the haves and the have-nots so stark than in the slum called Kangemi. On streets barely worthy of the label since there is no tarmac in sight, around 400,000 people live, most getting by each day on less money than we would spend on a loaf of bread.
Last year Pope Francis visited this home of the poor and described Nairobi's slums as the "wounds" of inequality.
As he looked out on homes of corrugated iron where families live amid rivers of raw sewage he lambasted what he called "new forms of colonialism" that exacerbate the "dreadful injustice of urban exclusion".
In Kangemi even water cannot be taken for granted and is bought in 20 litre containers leaving families facing hard choices between eating and washing.
Violence is endemic, as is the abuse of drugs and a local hooch called Changaa.
HIV is widespread with stigma and a lack of access to drugs to blame.
Amid the despair and the filthy streets lies St Joseph's Church, where a plaque celebrates the Pope's visit. It is here people like Betty Hamud work day and night to eradicate gender-based violence - an issue targeted with money from Trocaire.
Known locally as Mama Betty, she is a mother figure in Kengemi where she helps women subjected to the most appalling violence, often by men off their heads on drink or drugs. She does not bat an eyelid as she tells of one woma in the area whose arm was chopped off with a machete by a violent partner.
This is the culture of violence against females she is fighting to stop being "taken for granted".
She deals daily with women who are sometimes "killed, have lost 400k limbs in attacks, have been stabbed or even burned with kersosene".
Women, she adds, are raped and sexually assaulted with bottles.
Sexual abuse of young children is also common with gangs of older boys attacking younger ones.
One of those Mama Betty is helping overcome a life of violence is Margaret Abukuse. Her life has been one of abuse and misery at the hands of a husband often high on drugs. She says with resignation "he beats me all the time".
And as if the constant violence is not enough, the 48-year-old is HIV positive.
She has drugs to treat the condition, but they are powerful and when you skip meals so your children do not go hungry their effectiveness is diminished.
These are the hard choices made by the people who call Kangemi home. Two of Margaret's young sons were "sodomised" by gangs that roam the slum.
But little is done as the older boy blamed for the attacks is apparently mentally unfit and himself the victim of sex abuse.
Fr Angelo Munduni Dema, who works at St Joseph's, also knows of the violence beneath the surface and tells of one day seeing a man run towards him with his insides in his arms after being slashed across the stomach.
He said part of their work is to overcome "cultural stereotypes" in which women have to be "dominated".
Stephen Anguva, who works for the Westland Gender Based Violence group, added families face stark choices daily.
He said: "There's no running water, just a big truck that comes every day with a container on it so school children are sent to fill 20 litre containers every day after school.
"They're very heavy, especially for a child that probably doesn't have a very good diet.
"Also the water costs money, about 10 shillings [around 10c], so families have to make choices like do they wash clothes or prepare a meal.
"Even though these are the poorest people they are paying the most for water. There's no hygiene, so they get sick and when they get sick it spreads and everyone in the family gets it. It's a miserable life."
St Joseph's is home to a programme called Uzima, which means fullness of life, aimed at helping people tackle head-on HIV, gender-based violence and the extreme poverty that dominates every facet of life here.
The men and women who come to Uzima are in search of what the aid agencies call empowerment.
In reality, the people like Betty Hamud and Fr Angelo are there to help give people a voice and the more who they can help shout from the rooftops, the greater the hope.
