Dr. Edward Lahiff:

It is about the diversity of land rights. If we are to recognise people's livelihoods and property rights, it is not a question of just one western model of the fixed farm with a fence around it. Many people in many parts of the world are pastoralists, not just for cultural reasons but also because that is the system of agricultural production that makes sense in semi-arid areas. Governments tend to be slow to recognise the rights of pastoralists. If they were to stay put, we could educate them and give them health services, but they move around and, therefore, are an awkward squad. That means working with governments to recognise that a different model of health care and education is necessary to reach them.
