From a little seed ...

In many developing countries, and especially in Africa, nations needs to pay attention to their agricultural productivity.  Rising populations mean that more food must be grown - and yet land is disappearing for bigger towns and citIES, mines, forestry and so on - meaning the percentage of land devoted to agriculture is reducing.

If a government,. perhaps with help from its national productivity organisation, aid agencies, a university or the private sector, can show how targeted action can improve agricultural productivity…. they can demonstrate success and make the case for more targeted productivity initiatives in other sectors.

Nothing succeeds more than demonstrating success.  Quick wins are essential in any longer-term change project. So, choose a sector (agriculture?), initiate a productivity campaign, demonstrate success (by measurement before and after) and watch others climb on board. 

Within your organisation, too, simply replace sectors with processes - and the same model applies.  Show you can do it with one process  - and people want to share the success, extend the success and repeat the success.
