Revision history [back]
I can agree totally with what Martinager posted.
My experience is in north east asia, working more specifically with greenhouse systems. In most cases if the farmers were left to their own devices they would simply ignore the drip system (we provided full instruction in the local language, but I guess the system is just too foreign). If we helped them setup the system and showed the how it works, uptake was much better - but unfortunately I would have to ask my colleagues whether this was sustained over the longer term. Some of these places experienced severe water scarcity.
I think for most people in most situations, to make it work would require a good amount of hands on training and guidance to get the system setup and running, and then frequent refresher training and troubleshooting sessions - probably at least twice a year.
