yes, uganda m7 tamed their karamoja, but kenya is different ballgame - we are talking 2/3 of the country. Anyway I think infrastructure will help; good roads; mean police can respond quickly; telecommunication and all that.How you merus survive and thrive around Isiolo is commendable.
You need to extend Meru National Park to those areas - so it become a barrier - the gov also need to buy such border land - and turn into animal conservancies - teeming with KWS/Police.
This will stop inter-tribal conflicts.
Northern part of Kenya has never been pacified its still wild wild area, Museveni obviously knows too well security manenos x100 compared to gatheca he knows that's playing with Russian roulette. If Meru is most developed place in those areas and 300 armed Turkanas can go there in broad daylight at 12.30pm with 0 detection and rain bullets on police and GSU that's tell you alot. In more remote areas simply no government exist
