Data sources
Primary data were collected through six institutional survey rounds in 1984, 1993-1994 (under ISNAR’s “Indicators Series Project”), 22008-2009, 2012-2013, 2015-2016, and 2017-2018 (under ASTI). These data were combined with a number of secondary data sources:
ART (Agricultural Research Trust). 2011. About ART. www.artfarm.co.zw/FactSheet.htm Accessed January 2011.
UZ (University of Zimbabwe). 2011. Faculty of Science: Biological Sciences. www.uz.ac.zw/science/biology/# Accessed January 2011.
For additional secondary sources that were used to construct the pre-1991 data series, see appendices and reference list in Roseboom, Pardey, Beintema, and Mudimu (1995) Download PDF.
Estimation procedures
- For a number of agencies, research staff and expenditure data were missing for certain years. These have been interpolated or in a few cases extrapolated.
- Expenditures for the higher-education agencies are estimates based on the average expenditures per researcher for the government agencies.
- Salaries and living expenses of many expatriate researchers working on donor-supported projects at the (often main) agricultural research agencies are paid directly by their respective agency. The average implicit costs of expatriate R&D staff were calculated in the early 1990s (see Appendix 2 in Roseboom, Pardey, Beintema, and Mudimu 1995), and have been extrapolated to more recent years using salary averages of a few CGIAR centers.
