La construction des barrières de séparation s’est accélérée après la fin de la guerre froide : on en recense une cinquantaine déjà érigées ou en cours d’édification. Elles rendent parfois les frontières incompréhensibles, comme au Bangladesh.

CAIN : Victims : Visualising the Conflict : Map Set 21 : Deaths Close to Peacelines
▻http://cain.ulst.ac.uk/victims/gis/maps/gismaps-21.html
A first question is how many peacelines are there in Northern Ireland? There appears to be some disagreement on the number. CAIN states the following in its Glossary of Terms:
There were approximately 35 peacelines in existence by 2001. Of these 26 were in Belfast, mainly in the west and north of the city. Outside of Belfast there were 6 peacelines in Derry, 2 in Portadown, and 1 in Lisburn. By 2007 the number of peacelines had grown to 46 walls or fences and 11 gates (Belfast Telegraph 26 April 2007).
However, whenever researchers approached the Northern Ireland Statistics and Research Agency (NISRA) to obtain the shapefiles for the peacelines in Belfast, they were told there were 22 peacelines in Northern Ireland. The apparent discrepancy may be due to different agencies being responsible for the building and maintenance of different peacelines, or it may partly be due to the joining of some peacelines which might be considered as separate walls by other groups and organisations.
The next basic question was when were the peacelines built? This is where the research plan ran into a wall of its own. Those with responsibility for the peacelines were only able to provide specific dates of construction for seven of the walls out of the 22 for which shapefiles were available. To obtain dates for the other 15 peacelines would probably require quite a bit of library research and unfortunately the project could not afford the time. So rather than a detailed statistical analysis of the full set of data the researchers settled for a tentative exploration of the information for the seven peacelines above.
