Ticks Tick Borne Dis

Published: February 2012

Two regions (Jimma and Dire Dawa) in Ethiopia were investigated for the presence of soft ticks. Although no Ornithodoros spp. ticks were collected during this survey, published records of their existence in Ethiopia were found. An overwhelming infestation of Argas persicus was revealed in a village located adjacent to Dire Dawa. These ticks primarily were feeding on poultry, but were also biting humans. Furthermore, hard ticks were collected from livestock and companion animals in these regions. Collected ticks were assessed for Borrelia by real-time PCR followed by conventional PCR and sequencing to identify species present. A. persicus ticks were found to carry B. anserina in 3 of 40 (7.5%) A. persicus tick pools, whilst hard tick pools yielded 2 of 16 (12.5%) positive for B. theileri. Collectively, these borrelial species and their tick vectors are likely to have an important economic impact of particular relevance to subsistence farmers in Ethiopia.

This review examines the efficiency of live animal and meat value chain from producers to consumers in Ethiopia. Ethiopia has a large livestock population, but the marketing system for live animals and meat remains underdeveloped. Several challenges hinder efficient transactions, including poor infrastructure, illegal cross-border trade, lack of market information, traditional production methods, and absence of grading systems.

Impact of multiple maize technology package adoption on the production efficiency and food security of smallholder farmers in Ethiopia: Evidence from the Sidama region.

Heliyon

January 2025

Lilongwe University of Agriculture and Natural Resources, Department of Agricultural Economics, and African Center of Excellence, Agricultural Policy Analysis-Big Data, Lilongwe, Malawi.

This study aimed to investigate the individual or combined impacts of multiple maize technology package adoption on the production efficiency and food security of smallholder farmers in the selected districts of Sidama region of Ethiopia. The cross-sectional data of 424 sample farmers owing 545 maize plots were collected using multistage sampling approaches. The selection-bias corrected multinomial endogenous switching regression (MESR) model was employed to assess the impact of improved maize seed, chemical fertilizers, and row planting adoption on the production efficiency and food security of smallholder maize-producing farmers.
