The greatest contrast we have seen was that between the southwest of the country (Banfora area) and the north (Dori area). In the southwest there are large sugar cane plantations, waterfalls and generally more green things. By contrast, located on the edge of the Sahel, northern towns are very sandy with little vegetation and not much in the way of agriculture. With the year in this part of the world split into a wet and a dry season, people need to grow enough food during the wet season to tide them over for the year. However, people in the north are unable to do this. Even in the years of 'best' rainfall, people only have enough food to get them through to the end of March (with the wet season starting again in May and the next harvest in September). Due to the lack of rain (and therefore no prospect of market gardening) there is very little in the way of employment in the north during the dry season. As a result, migration is a necessity for many people to enable them to earn enough money in the dry season to purchase the food they need to keep the family going. Unless a year's rainfall (and therefore harvest) have been particularly bad, 2 or 3 sons from each family generally migrate somehwere to earn money that they send back to the family to buy food. During those years when rainfall is really bad, older men and "even women" may also migrate in such a way.
By contrast, people in the southwest tend to migrate not because they have to in order to have enough food (although this may still be the case some years) but because there is little work during the dry season and so little opportunity to earn money. The large majority of people migrating from locations in all the regions of Burkina Faso that we have visited go to Cote d'Ivoire. People form the north also head to the southwest but Cote d'Ivoire seems to be the promised land of plantation work and pennies.
On our most recent visit to the East of Burkina (Fada N'Gourma) we were struck by the nice feel that the town had. The east is little mentioned in terms of migration within Burkina, either as a place of departure or arrival. It seems that it is a nice place to live as the land is fertile and they have bins in the town (a rare thing here). So people migrate to there from nearby. However, there seems to be a cut-off distance where the investment neccessary to travel to Fada is such that one might as well head to the southwest where the soil is more fertile and the harvest more secure.
I think thats enough on migration for now. One village we visited in the east had the unenviable position of being able to look at the pylons carrying electricity that they could not use from the dam that they could not use for watering their crops as it was needed to generate the electricity that they could not use.
