With demand for food set to double by 2050, with a third less water, increasing loss of arable land and nutrients, with declining research and with climate change, the world is facing the likelihood of very serious famines in the coming half century - although most governments have not yet woken up to this. Technically, one of the biggest challenges is to increase water use efficiency in crop production worldwide by about 200-250 per cent over today's levels.
I am interested in hearing from members of this network about the techniques which they regard as most effective for sharing new knowledge with farmers in developing countries. These can be high tech or low tech - whatever works in your country in helping farmers adopt new technologies.
Particularly I wish to hear your suggestions for overcoming the language barrier and socio-cultural barriers, so we can quickly transfer new farming methods to people in ways they can understand and adapt to their culture and environment.
Your replies will assist a study I am carrying out for an international agricultural research agency on better ways to deliver new science and technology to poor farmers.
