Of course, many of these land-use issues are tied to resources, development control and questions of tenure; however it may be overly simplistic to reduce a conflict as long-standing and multifaceted as that in the DR Congo to merely one over herding rights, as the article seems to. Despite this, the land-use argument certainly carries a great deal of credibility.
From an urban development perspective (and by 2035 the United Nations predicts much of Africa will have become urban), land-use and tenure issues seem to be the most common causes of triggers of ethnic or religious conflict within Africa's burgeoning urban slums. Again, the nuance here is that while many of these conflicts take the form inter-ethnic, tribal or religious violence, the underlying root cause is usually one access to resources, most frequently potable water or development rights within a squatter community - with the underlying irony being that as these are squatter communities, no one has de facto legal rights to develop.
Despite this, possession is frequently 9/10ths of the law, and slum land-lords have been happy to illegally erect tin-sheds and then rent them out at usurious rates in places like Lagos, and to play one ethnic or religious group off against the other in cases where squatters begin to agitate for increased tenure security. Further complications stem from inconsistencies within competing legal systems - from colonial era (though still standing) laws and conflict with new laws passed post de-colonization to conflict with existing indigenous, though informal, tribal laws and norms holding precedence within many areas.
Thus many countries, for example one I have experience working in: Ghana, are seeking to mitigate conflict through the reform of land tenure laws and the normalization of traditional tenure conventions with the legal code. What this means is that increasingly traditional tribal chiefs who are making land-use decisions in practice will be further empowered to do so by the state, thus making their decisions formal land-use policy. This strengthens the legal legitimacy of 'traditional' semi-legal conventions while also allowing tribal chiefs to serve as conflict resolutions bodies.
While the empowerment of traditional tribal chiefs to serve as 'customary land managers' may be in imperfect solution, it is one that has great deal of salience with many living in African cities and villages and the further empowerment of chiefs as land-managers could, in many ways mitigate land-use conflicts and thus prevent bloodshed.
