1 Workshop on World Programme for the Census of Agriculture 2020 Amman, Jordan May 2016 Use of Technology for field data capture and compilation Technical session 19b Michael Rahija Global Strategy (main author) Jairo Castano Senior Statistician Leader, Agricultural Census and Survey Team FAO Statistics Division

2 Overview Overview of CAPI: description, advantages, disadvantages, products on the market Overview of Survey Solutions features Country examples: Indonesia and Tanzania

3 What is CAPI? Computer Assisted Personal Interview (CAPI) software allows recording responses on a computer or tablet instead of paper.

4 What are the advantages of CAPI? Easier Survey Management Reduced variables costs (No transport costs, no storage costs, no printing costs, no data-entry costs) Reduced time from data collection to analysis and reporting Higher quality data (Enforced skip patterns, validation conditions, look-up tables)

5 What are the advantages of CAPI? Novel question types Geo reference, photos, barcodes scanning (for national IDs) Closer field monitoring Export paradata for monitoring activities during interviews (e.g. start & end time) Almost real time export of micro data export Easier to implement changes to questionnaire No need to send questionnaires back and forth to field

6 What are disadvantages of CAPI? High fixed cost Can be reduced by using for multiple surveys Requires more preparation time programming and testing questionnaire, procurement Time savings on back-end from no data entry compensates Many times requires connectivity Risks can be reduced by using 2 sim cards, backup paper questionnaires, etc.

7 CAPI Products Census and Survey Processing System (CSPro) Developed by the US census bureau and funded primarily by USAID. Widely used, but lacks survey management tools and requires programming knowledge. FREE + programming costs Open Data Kit (ODK): Core developers at UoW Dpt. Of Computer Science. Open-sourced, funded partially through donations of users. FREE+ programming costs My Survey Solutions: Development supported by the GS, and first version released in Closed source, but integrates data management tools, and requires little to no knowledge of programming. FREE

8 FAO and Survey Solutions Global Strategy has implemented surveys on small sample surveys in Tanzania, Indonesia, and Jamaica World Bank in partnership w/ NSOs have implemented surveys reaching 200K respondents in Malawi, 400K in Uganda, and 2.7 million in South Africa.

9 Survey Solutions Features User friendly survey management system built right into the software. Survey designer that requires NO programming skills Cloud based data storage and transfer Geo references questions (holding location) Can accommodate any type of question User-friendly Android application for data entry

10 Survey Solutions Features (cont d) Documentation on every part of the system available E-learning course to be available later this year (13 modules) Data export available in SPSS and STATA formats. DDI compliant metadata automatically generated. Automatic paradata tabulation for field

11 Country Experience - Indonesia BPS with technical assistance from the Global Office of the GS implemented multiple agricultural surveys in 2 provinces using SuSo. Data was collected on around 400 households. At the end of the project, BPS purchased 2000 tablets and is scaling up CAPI to 7 provinces.

12 Country Experience - Tanzania The Ministry of Livestock and Fisheries Development (MLFD) undertook an randomized control trial (RCT) involving 600 livestock extension officers. CAPI allowed results to be available in less than one month after baseline survey. MLFD looking for more opportunities to expand data collection using CAPI.

13 Country experiences on use of CAPI, CATI, GPS and other technologies in census Countries are using more and more IT technologies in agricultural censuses for: data collection (CAPI, CAWI, CATI); identification of location for the field operation of each enumerator (GPS); monitoring the progress in field operations on the web in real time.
