The Bank really is not "scanning the world for the most relevant, useful, and cutting-edge practice in areas of relevance". It is only interested in the economics of every sector. The actual science is of little interest and/or left up to some consultants, whose credentials really no one can take the time to check. This is how the Bank in fact got out of agriculture. All we ever talk about is prices, not the science behind it. And then it got mixed up with rural sociology and the like, for further blurring. And of course it hires generalists who often have no idea about the science of their sector.
