Britain is to spend £1.8bn on the economic development of poor countries next year, more than double the amount spent in 2012-13, the international development secretary announced as part of a "radical shift" in policy that focuses on making it easier to do business in these states.

In a rare demonstration of public dissent, dozens of Cuban artisans and vendors protested in the city of Holguín this week, marching to local government offices and demanding the right to work without government harassment, witnesses said.

Surrounded by samba music, residents of the Metro Mangueira favela were celebrating after a week of conflict. The small community is located next to the Mangueira favela, where 18,000 people live and is the headquarters of "Estacao Primeira de Mangueira", a famous samba school, where musicians like Jamelao and Cartola composed and played.

Over the past few decades, it has become possible to speak of a "global food system"—shorthand for the trade patterns, shaped by multinational companies, that move raw agriculture commodities and processed food across borders. Yet as this fascinating new Oxfam study shows, there are still huge differences in people's experience of food across the globe. Oxfam ranked nations on four criteria: whether food exists in plentiful supply, whether it's broadly affordable, whether it's of good quality, and whether it's causing high rates of obesity and diabetes.

Pope Francis on Sunday named his first batch of cardinals, choosing 19 men from Asia, Africa and elsewhere, including Haiti and Burkino Faso, to reflect his attention to the poor. Francis made the announcement as he spoke from his studio window to a crowd in St. Peter’s Square. Sixteen of the appointees are younger than 80, meaning they are eligible to elect the next pontiff, which is a cardinal’s most important task. The ceremony to formally install them will be held Feb. 22 at the Vatican.

The bumpy ride in the rickety van heads up the steep hill into Morro da Providência, this city’s oldest favela. Last stop: a small, silent square with a hardware shop, bar and pair of young policemen in armored gear toting machine guns, patrolling the still-unopened cable-car station that the city has recently built. The port spreads out below. Spurred by two looming mega-events — the World Cup next year and the Summer Olympics in 2016 — local officials are struggling to reinvent this onetime third-world city with a first-world economy.

Pope Francis is once again shaking things up in the Catholic Church. On Tuesday, he issued his first “apostolic exhortation,” declaring a new enemy for the Catholic Church: modern capitalism. “Some people continue to defend trickle-down theories which assume that economic growth, encouraged by a free market, will inevitably succeed in bringing about greater justice and inclusiveness in the world,” he wrote.
