Professor Fidelma Ashe:

The cost would be a lot higher. The thing is we do not have to do it all at the one time. We can do it in stages and that is probably the best way to do it because we can have the feedback from phase one and then reformulate phases two and three. We could start to work with particular groups in a particular area along the Border, for example, which would seem to be an important area to start this work on. Then from that point we could start to reach out. We do not have to finance the entire programme but we can finance it in stages, see what the benefits from it are and whether the benefits are cost-effective. Then we could move from that point forward.
