In order to answer this question, this paper investigates the impact of JICA training on the adoption of rice cultivation technologies and productivity in an irrigation scheme in Tanzania. By using a unique five-year panel data set and spatial econometric techniques, we found that non-trained farmers learned new technologies from trained farmers through social networks and by observing their plots. As a result, the paddy yield of directly trained farmers increased from 3.1 tons per hectare in 2008 to 4.7 tons per hectare in 2012, while that of non-trained farmers increased from around 2.6 tons per hectare in 2008 to 3.7 tons per hectare in 2012. publisher: JICA Research Institute date: 2015-03 type: Monograph type: NonPeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/9092/1/JICA-RI_WP_No.90.pdf identifier: Nakano, Y and Tsusaka, T W and Aida, T and Pede, V O (2015) An Empirical Analysis of Expanding Rice Production in Sub-Sahara Africa, The Impact of Training on Technology Adoption and Productivity of Rice Farming in Tanzania: Is Farmer-to-Farmer Extension Effective.
