An adaptive trail result that can make larger impact for more communities to adopt
The introduction of green revolution in india during sixties is a clear example of larger adoption of agricultural technologies
it is more seen in case of high yielding varieties, fertilizers and pesticides
We see the examples of soil health service, resource conservation technologies are quite slow in adoption specially in intensive cultivated areas with small and marginal farmers more in numbers
Regards
Are there studies, reports, papers that indicate that after the adaptive trail confirmation at farmers field that thee has been a large adoption of agricultural technologies by communities. This is a request to quote in the forthcoming of my research papers
Dear Ananth and Naveen,
I agree with Naveen that the Green Revolution is a good example but we must realize that this mostly happened with Extension Services involved in demonstration trials (let's do away with the "trails") in farmers' plots.
Generally, other good examples are introductions of irrigated agriculture where trials have shown that availability of water improves yields on soil with sufficient nutrients and with measures to prevent leaching of nutrients (where salts do not necessitate such leachings). There are many examples, including agriculture along big rivers as the Blue Nile and the Nile in Sudan and Egypt, but you may find that obvious. Subsequently large irrigation systems were established.
There are examples of case studies in my "Applied Agrometeorology" (Springer, 2010) where for example for irrigation the services in Cuba again show that such taking over from trials is often guided by Agrometeorological or Meteorological Services. This is also illustrated there with examples of mulching in China (with and without the use of plastic on ridges). Further examples there, are wind protection in coffee and shade use in tea gardens, that have been adopted by whole areas. I have considered these as "agrometeorological services" (now "climate services for agriculture". I have in the same book collected other examples (that is case studies) from China where Provincial or sometimes even Sub-Provincial Services were involved in the spreading of results obtained at field trials in research stations.
I feel that the spontaneously spreading of successes does occur (the case study of pebbles used in Ningxia, China, over large areas for melon growing is an example) but the involvement of Services with demonstration plots is more often occurring. This is the more common way of spreading of successful technologies.
Best wishes, Kees
While we have not strictly conducted adaptive trials at farmers' fields, we have a done a case study of adoption for a "best practice" for cacao that our program adapted for mass dissemination and extended via demonstration plots to over 20,000 cacao producers with a 60% adoption rate over 2 years.
Again, whereas we did not conduct field trials first, we did extend the technology to a large group of producers with good success, there are spill-over effects that we have not measured but are obvious as extension agents from other programs in the area have adopted our technique and are disseminating it.
If you would like a copy of our case study, please feel free to request it.
Hi, I woudl suggest you to look at the work of the Rice-Wheat Consortium for the Indo-Gangetic Plains (RWC), an ecoregional program of CIMMYY-IRRI and many other CG centers. They have successfully tested and promoted numerous resource conservation technologies in the IGP.
