This 9 minute film is an insight into the work of soil and water conservation expert, Dr Chris Reij. In June 2012
I joined him on a whistle-stop tour of communities in southern Niger. This area is right on the edge of the Sahara and yet growing in the sandy soil are an abundance of vegetables, cereal crops and trees.
The film was made with funding support from IFAD.

The videoclip Ponto de Luz, of Sara Tavares, was created using the Stop Motion technique, which means taking pictures to objects, persons or situations, frame by frame, putting then everything together in a video sequence which creates the illusion of movement. From here, comes also the Timelapse technique, which means taking pictures with a regular constant break, for example, minute by minute, during a long period of time which creates the illusion of time passing by (shadows, clouds, sea, cars, people, etc)

For this vídeo it were taken 4500 photos, and used in the final edition 3000.

This vídeo was made and directed by Mercês Gomes e Ricardo Oliveira Alves.

UK sorry for 'pervasive racism', after report finds 350,000 WWI troop deaths weren't commemorated

They hover over ponds and pools and inhabit the banks of rivers and streams. With their dazzling metallic colours and unique ways of flying they are truly jewels of the air. This film presents dragonflies as they have never been seen before. Fascinating close up shots take us into the world of these insects, which have lived on earth since the age of the dinosaurs. Spectacular super slow motion shots and elaborate computer animation uncover, for the first time, how dragonflies capture their prey at lightning speed while flying and how they mate in the air. Underwater photography reveals the development of the predatory dragonfly larvae while time lapse sequences show the emergence of the fully grown insect. However these amazingly colourful flying acrobats are in danger. The dragonfly's preferred habitat in and around water is rapidly diminishing, which, in Europe alone, has pushed around 80 species to the brink of extinction.

War and the Diamonds of Sierra Leone.

This year, Europe has seen unprecedented numbers of refugees and other migrants cross over its borders - well in excess of 350,000 people, who - driven by fear of war and terror or by poverty and the promise of a better life - have made the treacherous journey by land and sea out of the Middle East and Africa.

Very few of them will have official status or the right documents, most are short of money and don't know how they will survive, but all hope they will find a safe haven - be it temporary or permanent - in a continent that seems peaceful, prosperous and secure. And for some - the fortunate minority - that is indeed what they will find. They will be taken care of. But many won't. Desperate, vulnerable and ever fearful of deportation as illegal immigrants, they will be forced to live on the margins, to go wherever they can, and take on whatever work they can get to survive.

And that can lead them wide open to exploitation.

This is the illuminating story of just one group of last summer's arrivals: migrants into southern Italy who became reluctant recruits in a vast army of casual farm labourers. It is a story that says as much about modern Europe as it does about the migrants as the story touches the tens of millions of the continent's citizens who purchase or consume one of Italy's most famous foodstuffs: its rich, sweet, sun-ripened tomatoes.
