Pope Francis arrived in Uganda Friday on the second leg of his Africa pilgrimage, calling Africa the "continent of hope" and honoring Uganda's famous Christians. Francis arrived at Entebbe International Airport, where Ugandan President Yoweri Museveni, flanked by a military brass band and traditional drummers and dancers welcomed him. Francis, who arrived from Kenya and also is scheduled to visit Central African Republic Sunday, is in Uganda to honor the memory of a group of Ugandan Christians killed in the late 19th century on the orders of a local king eager to thwart the growing influence of Christianity. Francis arrived in Kampala after a busy final day in Kenya that was highlighted by his visit to one of the capital's 11 slums and a spontaneous, off-the-cuff monologue to thousands of Kenyan youths about preventing young people from falling prey to corruption and radicalization to go fight with extremist groups. In the Kangemi shanty, Francis denounced conditions slum-dwellers are forced to live in, saying access to safe water is a basic human right and that everyone should have dignified, adequate housing, access to sanitation, schools and hospitals. Residents lined the mud streets to welcome Francis, standing alongside goats and hens outside the corrugated tin-roofed shacks where many of the shantytown's small businesses operate: beauty parlors, cellphone "top-up" shops and storefront evangelical churches. Those lucky enough to score a spot at St. Joseph's parish erupted in cheers and hymns when Francis arrived, ululating and waving paper flags printed with his photo and the "Kariba Kenya" welcome that has been ubiquitous on the Pope's first-ever visit to Africa. Francis, known as the "slum Pope" for his ministry in Buenos Aires' shantytowns, has frequently insisted on the need for the three "Ls" – land, labor and lodging. Friday he focused on lodging as a critical issue facing the world amid rapid urbanization that is helping to upset Earth's delicate ecological balance. Kangemi is one of 11 slums dotting Nairobi, East Africa's largest city, and is home to about 50,000 people. The U.N. Habitat program says some 60 percent of Nairobi's population lives on just 6 percent of the city's residential land in these unofficial settlements lacking basic sanitation or regular running water. Francis denounced the practice of private corporations grabbing land illegally, depriving schools of their playgrounds and forcing the poor into packed slums, where violence and addiction are rampant. In January, police tear-gassed schoolchildren demonstrating against the removal of their school's playground, which has been allegedly grabbed by powerful people. After an outcry, the Kenyan government declared the playground the property of the school. He called for a "respectful urban integration" with concrete initiatives to provide quality housing for all. His message was welcomed by residents of Kangemi, who said the city only pipes in water three days a week, Tuesday through Thursday, but it's not safe to drink. Garbage collection goes to only those who can pay for it. Francis raised the issue of environmental deterioration in cities in his landmark encyclical "Praise Be," saying many megacities today have simply become health threats, "not only because of pollution caused by toxic emissions but also as a result of urban chaos, poor transportation, and visual pollution and noise." After the visit to Kangemi, Francis received a rock-star welcome at Kasarani stadium, where he zoomed around the track in his open-sided Popemobile to the delight of thousands of young Kenyans in the crowd. The stadium was so packed with the faithful that many more stood outside, unable to enter.
