Johanara, 10 ans, apprend le surf – Bangladesh – 24 janvier 2015

10 year old Johanara surfs January 24, 2015. The Bangladeshi surf girls are a group of eight outgoing and spunky girls ranging in age from ten to thirteen†years old living and working in Cox's Bazar, Bangladesh. Poverty is forcing them into an early adulthood, as they are obligated to shoulder the responsibility of earning money to help feed their families. Early each morning, rain or shine, they leave their homes and†make their way to the beach,†where they work selling jewelry and eggs until late into the night before returning home. Their families are unable survive without the girls' income. Most children who have been conscripted into the role of wage earners have little joy in their lives, but for the past year and a half they have been learning to surf and skateboard thanks to the efforts of 25-year old surfer, lifeguard, surfer, and beach worker Rashed Alam, his wife, American expat Venessa Rude, and the Coxs Bazar Lifesaving and Surf club. Surfing and skating empowers them, giving them an outlet to be children.

Jeune femme prise de douleur après un accouchement – Inde – avril 2015

Nazreen Khatoon winces in pain as she is repositioned by a nurse as she lies gravely ill while suffering from severe postpartum anemia at the Tezpur Civil Hospital in Tezpur, Assam, India, April 2015. Khatoon delivered her son, Kashari Pam, roughly three weeks prior, and returned to the hospital about two weeks after delivery when her condition worsened. When we met her, she was in dire need of both blood and iron, and was not receiving either from the Tezpur Hospital; she was eventually referred to a private hospital, where she was able to receive better care, but at a great expense to the family. Many of Assam's state-run medical facilities are often overcrowded and unhygenic, with an insufficient number of doctors, and patients sprawled out in the floors and hallways due to a limited number of beds. Assam has the highest rate of women dying in chidbirth and from pregnancy-related causes in all of india, where roughly 50,000 women die annually in childbirth across the country. Many families in Assam work on the tea plantations, where there is a high rate of pregnant and lactating women who are severely anemic due to poor diets and little to no prenatal care, leading to a high number of pregnancy complications.

Un jeune enfant souffrant de malnutrition est couvert d’un voile pendant sa guérison – Afghanistan – 6 avril 2015

Gul Ahmad, an infant boy suffering from acute malnutrition, is covered by his mother's scarf while being treated in the therapeutic feeding centre ward at the Medecins Sans Frontieres (MSF) administered Boost Hospital in Lashkar Gah, the capial of Helamnd Province in southern Afghanistan. Malnutrition, according to MSF staff, is a chronic problem in Afghanistan. In most cases it is not malnutrition that sees children admitted to hospital but an illness that has been brought on by the child's inability to fight off infection because its body is so degraded of vital nutrients. In infants in Afghanistan, malnutrition is often the result of mothers feeding their baby's formula or even tea instead of breast milk. The reason for this is generally a lack of access to information and education for new mothers.

Un policier des frontières va arrêter un migrant caché dans les dunes – Texas – février 2015

February 2015 - Riviera, Texas - Border Patrol Agents apprehend migrants hiding in sand dunes. These migrants were avoiding the interior checkpoint located in Sarita, Texas, on Rt. 77 North to San Antonio. Interior checkpoints are located on northbound highways 60 miles north of the Rio Grande River in Texas. This is the nation's busiest corridor for human smuggling and migrants must circumvent authorites by traversing private ranches on foot. This final portion of the journey yields the majority of migrant deaths in Texas. Border Patrol agents expertly track footprints and pathways through miles of ranchland to apprehend migrants. Most apprehensions happen at night, with the aid of infrared technology.
