@Simo, @Lolest has a valid point. With the cash will also come responsibility for an entire county bureaucracy. If this cash was to entirely applied in development activities, this would be nirvana, and your excitement would be justified. As things are, only about 35% of the 2011/2012 budget was development spending. The rest was recurrent expenditure (salaries, fuel, operating costs Etc)
The counties will certainly have more funds for development, but it will all depend on how efficiently they manage available resources. There will be a temptation for some to maintain bloated bureaucracies - nepotism, regionalism - meaning very little is left for development.
The other consideration is that Kenya only raises enough cash to meet its recurrent expenditure. Very little is left over from tax revenues to meet development costs (I think there was 50b or so in the 2011/2012 estimates) Some clever guys at Treasury knew this and came up with the contentious revenue sharing system which excluded loans and grants from the revenue to be shared to counties!! The result is to give the central government control over almost all development projects funded by development partners, and through the back door relegate counties to paying for recurrent expenditure. No much to celebrate in this arrangement.
I strongly urge you to temper your excitement with a degree of caution. Unless you want to set yourself up for major disappointment.
