Watch this video (above) on 'flying rivers' (English subtitles).
With its large surface area and abundant rainfall, Brazil receives more rain in a year (estimated at 15,000 cubic kilometres (3,600 cu mi)) than any other country. In 2007, the Swiss-Brazilian pilot Gérard Moss joined with scientists to initiate a project to evaluate the source of the atmospheric water over Brazil and examine the possibility that recent droughts in the country are being caused by the deforestation of the Amazon rainforest. This is the Flying Rivers Project. The primary objective of the project is to "try to ascertain the origin of the water vapour, rainwater and river water in the areas crossed by the flying rivers". Other objectives are to scientifically evaluate the processes involved in this water transfer and to educate the public in understanding the importance of the Amazon rainforest as a source of the water that is vital for their lives and the economy.
