Abstract
This dissertation consists of three papers on household decision-making towards livestock disease control in cattle in northern Tanzania to address emerging control technologies for a smallholder system with a particular focus on foot-and-mouth disease. My research uses data from a household survey on 489 households I performed in 2016 in the Serengeti and Ngorongoro districts of Tanzania. The first paper examines household decision-making for foot-and-mouth disease vaccination relative to variations in temporal and spatial risk. I use a commonly used stated preference survey methodology, willingness to pay, to elicit decision responses for a routine vaccination strategy applied biannually and an emergency strategy applied in reaction to a spatially varying hypothetical outbreak. In the second paper, I additionally employ the stated preference survey approach with the double-bounded contingent valuation methodology to extend the analysis in the first paper by assessing the value of enhancing vaccine information through a hypothetical, communal diagnostic test. The collective approach to testing addresses the potential for households and the community jointly to acquire information about the circulating type of foot-and-mouth disease to enhance vaccine decision-making. Finally, in the third paper, I compare the current use of antibiotics to treat secondary infections from foot-and-mouth disease with vaccinations for other livestock diseases to examine how each of these inputs influences livestock production and household wellbeing. I use two-stage, instrumental variable regression techniques to separate production and consumption decisions by first defining household use of antibiotics and vaccination, then assessing the effect of these decisions on livestock production and household expenditures on food, health, and education. This dissertation provides empirical evidence that vaccination and early detection for endemic livestock diseases, such as foot-and-mouth disease, can both improve measures of household economic and nutritional security and complement existing household disease management practices.
