Case Study Survey and Experimental Intervention in Tanzania for “An Empirical Analysis on Expanding Rice Production in Sub-Saharan Africa”

Project Timing

Baseline: September 2017- June 2018






Japan International Cooperation Agency (JICA)

Current Status


The aim of the research project is to analyse the impact of the Coalition for Africa Rice Development (CARD) initiative.  CARD was first launched in May 2008 to address the need to improve agricultural production in African countries.  A number of programmes have been implemented related to expanding rice production in Sub-Saharan Africa in an effort to alleviate poverty and to improve food security. The main objective of this particular research project, led by JICA’s Research Team, is to analyse the impact of the CARD initiative on rice productivity and poverty reduction. In addition, the effectiveness of new agricultural technology and its dissemination will be assessed.

This evaluation will examine the impact of a training programme delivered to farmers on adoption of cultivation practices and rice yields.  EDI’s responsibilities are to conduct a household survey in rice-growing households and to measure the land size of rice parcels cultivated by the households using GPS readings captured with surveybe. The intervention will consist of a training programme, both centralised and in their villages, to farmers in major rice growing regions alongside them receiving farming inputs. The sample includes approximately 400 rice grower households from 8 villages (distributed in 4 districts). The villages are divided into 2 categories: TANRICE and Experimental villages, which are neighbouring villages. Additionally, in each village the respondents are divided into three groups: Key, Intermediate and Ordinary Farmers. The main difference among these groups is the type of inputs and training that will be provided.

After the training, a follow-up survey will be conducted to compare results before and after the training was delivered.  As part of the intervention, selected households will be provided with free inputs including rice seeds and fertiliser.  EDI is responsible for sourcing these inputs, organising the packaging and transportation to the villages, and the final distribution to all selected farmers. EDI is also responsible for providing logistic support for the intervention by selecting participants and mobilising them.


Field work ended on 22nd of December 2017.  The EDI team consisted of 2 Team Leaders and 16 Interviewers. The target sample of farmers was reached, and the mobilisation of farmers was successful. The teams successfully located the selected farmers, interviewed them, and measured their rice parcels.
