New technologies are at the core of sustainable agricultural growth and rural poverty alleviation, says Khondoker Mottaleb, an Agricultural Economist working within CIMMYT’s Socioeconomic Program. However, he explains, despite the visible benefits of using new agricultural machinery or farm management practices, overall uptake remains low as a range of factors continue to limit farmers’ ability to invest.
In a bid to enhance irrigation efficiency, Bangladesh has tried to introduce and popularize the use of axial-flow pumps (AFPs) for surface water irrigation. These pumps can lift up to 55 percent more water than a conventional centrifugal pump, but despite the obvious benefits, there has been limited uptake in targeted areas of the country. From 2012-13, a CIMMYT initiative made AFPs available for purchase for farmers in the southern regions of Bangladesh, but as of September 2017 only 888 had been purchased by lead farmers and irrigation service providers.
A recent study by CIMMYT in Bangladesh used primary data collected from 70 irrigation service providers – each of whom was given a free AFP for one season under a demonstration program – to examine user perception of AFPs and the major constraints to their adoption. It found that even though the use of AFPs can significantly reduce irrigation and overall crop production costs, more demonstrations and awareness-raising programs are needed if uptake is to be increased in target areas.
The study also highlighted the need for continuous modification of new technologies based on farmers’ requirements, with Mottaleb emphasizing that these must be adapted to local demand specifications, and that prices must be competitive with those of alternative technologies in order to ensure rapid uptake.
This study was supported by USAID through the Cereal Systems Initiative for South Asia – Mechanization and Irrigation (CSISA-MI) project. It was also supported by USAID and the Bill and Melinda Gates Foundation through the Cereal Systems Initiative for South Asia (CSISA) Phase II project.
