I chose to do the Scotsman Project that aims to reduce Post harvest losses in Africa. this is a very wide issue that effects lots of different countries, environments and has lots of different problems to look at.

I started my repurchaser by googling the article that the brief was originally based on. (http://www.theguardian.com/global-development-professionals-network/2013/aug/22/weather-stations-agricuture-data-africa)

From this I did 2 things.

1) picked out key things I wanted to research
2) saved it to Delicious

Delicious showed me 9 other people had saved this article, It also suggested a number of other articles I may be interested in. After checking out a few of these articles I found a few people on delicious who were following similar topics to me.
