It’s once again time for our fortnightly roundup of photos from our bloggers. Over the past two weeks, they’ve captured street performers in Lima, volunteer ambulance squads in Bangkok and pirated-DVD sellers in Manila.

One of Nairobi’s many private buses. Recently the city has tried to crack down on bus operators who break the law, but the cheap and popular transport service seems to naturally resist regulation.

A vendor of pirated DVDs fans out his merchandise. The huge amount of bootleg videos produced and distributed in Manila may be hurting the Philippines nascent film industry.

A phone-card seller stands outside his shop in Accra. The city’s grab-and-go culture has made selling top-up phone cards an important source of income for informal workers.

In the back of a volunteer ambulance, an unpaid EMS worker readies for the scene of an accident. Such ambulances provide the bulk of first-responder services for Bangkok’s 12 million residents.

Before a line of cars, a juggler plies is trade. Traffic jams in Lima have created a captive audience for the city’s street performers.

Political graffiti in Kibera, one of Nairobi’s slums. Many are worried that next month’s presidential election will lead to an outbreak of violence in the city’s informal settlements.

A seller of herbal remedies at an informal market in Quiapo displays her wares. Even in modern Manila, people from all walks of life buy herbal medicines to cure their ailments.

Lima has an astonishing number of taxis — about 230,000, most of them informal — and their drivers play many roles, from fish haulers to roving psychologists.

A modified van that’s been turned into an ambulance. The unpaid workers of Bangkok’s volunteer ambulance services must often buy their own supplies — including the ambulances themselves.
