Abstract

This study was carried out in Ngorongoro, Kibaha and Bagamoyo districts to quantify the economic losses due to Contagious Caprine Pleuropneumonia (CCPP) and Peste Des Petits Ruminants (PPR). The study focused on direct losses, impact to food security and comparison of disease burden between the studied sites. Data were collected through household questionnaires and analysed using spreadsheet model to estimate direct losses attributed to CCPP and PPR. Multiple linear regression model used to determine the impact of disease losses to food security while independent sample t-test used to compare disease burden between two studied sites. Results indicated that CCPP accounts for 2,273,281TZS per household annually while PPR cause losses of 1,920,924Tsh and 1,162,562TZS in goats and sheep respectively. It was also found that PPR contribute significantly to food insecurity (p<0.01) while CCPP influence was insignificant. Ngorongoro experienced higher losses due to PPR (sheep =1,405,330TZS, goats =2,186,356TZS) compared to Coastal districts (sheep = 192,353TZS, goats = 877,293TZS) and the difference was statistically significant (P = 0.000) while for CCPP the impact was almost the same for both sites (Ngorongoro = 2,560,844TZS, Coastal = 2,185,192TZS). Economic losses found to be higher in goats than in sheep due to relatively higher prevalence and mortality rate in the former compared to the later flocks. CCPP losses are almost the same between two study sites because currently the disease is endemic in the country. However, the effect of these two diseases on food security varies across the production systems (pure pastoralism vs. agropastoralism). The findings suggests that the two diseases are of economic importance to the pastoral communities in Tanzania as they impose high economic burden and threaten food security therefore recommends fast tracking of availability and accessibility of CCPP vaccines with regular vaccination campaigns against PPR to minimize the impact.
