Next time you're on a stepper machine, spare a thought for the guy here in green. He's jogging on a metal treadle pump, balancing with two sticks, sucking water from the river and irrigating six acres of red peppers.

This nutritious and economically valuable crop couldn't grow here without the regular watering which our man here and his Oxfam-installed pump provide.

It takes six hours to water the field - and thankfully they do it in shifts.
