The difference is this costs 40 € and can clear a couple of mines for that money. Afghanistan is not exactly rolling in cash, so any cheap improvement is a valuable addition to the toolbox - it provides a way for poor communities to do something while they're waiting for America to donate enough money to clean up their mess.
My guess is that demining NGOs will be using something like this soon enough if it proves effective, though, so any donation dollar really is best sent there for maximum effectiveness.
