R.I.P Prof. Calestous Juma.




“As far as agricultural GDP is concerned, in today’s China additional investment in high-quality roads no longer has a statistically significant impact while low-quality roads are not only significant but also generate 1.57 yuan of agricultural GDP for every yuan invested. Investment in low-quality roads also generates high returns in rural nonfarm GDP. Every yuan invested in low-quality roads yields more than 5 yuan of rural nonfarm GDP. Low-quality roads also raise more poor people out of poverty per yuan invested than high-quality roads, making them a win–win strategy for growth in agriculture and poverty alleviation. In Africa, governments can learn from the Chinese experience and make sure their road programs give adequate priority to lower-quality and rural feeder roads”

There lies a great mind. RIP

RIP proff, this guy was contributed a lot in Kenya.

RIP mwalimu.

This is what I keep telling @spear, @mayekeke @gashwin and @kwido that the return on investment of roads like Thika road is quite low and the opportunity cost is quite high. Wacha wakuje wajisomee.

I said, n I repeat, you and me can never have a level discussion on matter to do with infrastructural development especially as pertains to our road network.
May the good Lord rest the soul of Prof. Juma in eternal peace.
