AbstractThe recognition of commercial agricultural investment led to the expansion of large-scale farms through eviction of farmers during the Derg and Ethiopian People Revolutionary Democratic Front (EPRDF) regimes. But anti-dispossession voices and investment driven violence have frequently occurred in post-Derg Ethiopia. This study thus attempts to uncover the political-economy of land acquisition and privatization of Birr and Ayehu farms. The necessary data for the study were collected through interview, questionnaire, focused group discussion and document review. The data collected through questionnaire was analyzed using descriptive statistics and the qualitative data was analyzed thematically. The findings of the study indicated that the farms were began during the Derg regime as public enterprises, and later privatized to Ethio-Agri-CEFT in a neo-patrimonial modality with a gigantic trend of land acquisition, legal distortion and violation of landholding rights. This poor and neo-patrimonial operation of farms jeopardized local livelihoods, created land use change and evoked stiff public grievance, political upheaval and polarized state–society relations. This indicated that the expansion of farms have brought lopsided development to party affiliated investors by dismantling local livelihoods. Ethio Agri-CEFT thus should respect legal frameworks and adopt inclusive developmental practices for its sustainability and success.

Abstract Background: Tuberculosis is a zoonotic chronic infectious disease caused by Mycobacterium tuberculosis complex (MTBC) that can be transmitted between humans and cattle. The aim of our study was to identify cross-infections of MTBC between humans and cattle on dairy farms in Sichuan Province, southwestern China. Results: We selected 6 large-scale and 5 small-scale dairy farms in Sichuan Province as research sites. A total of 378 dairy farm workers (except one pregnant woman) were screened for tuberculosis symptoms and examined by X-ray. One worker was diagnosed as tuberculosis, though the sputum culture was negative. In total, 99 of 10,224 (0.97%) cows showed positive results for the purified protein derivative (PPD) skin tests. Esophageal-pharyngeal (OP) secretions from PPD-positive cows were cultured and 21 isolates were obtained. Sequences of 16s rDNA, hsp65 and rpoB and 16s-23s rRNA spacer region were amplified and sequenced. BLAST analysis classified these isolates as nontuberculous mycobacteria (NTM) (18 M. nonchromogenicum, 1 M. hiberniae, 1 M. arupense, and 1 M. chitae isolates). Conclusion: This study indicates that the PPD-positive cows in these dairy farms were infected with NTM rather than MTBC. Tuberculosis cross-infection between humans and cows on dairy farms has been well controlled in this region.

Abstract Background Tuberculosis is a zoonotic chronic infectious disease that can be transmitted through respiratory secretions, causing simultaneous infection in both people and cattle. The aim of our study was to identify the co-infections of Mycobacterium tuberculosis between human and cattle in dairy farms in Sichuan Province, southwest China.Results We selected 6 large-scale dairy farms and 5 small-scale dairy farms in Sichuan Province, southwest China, as research sites. A total of 378 dairy farm workers (except one pregnant woman)were screened for tuberculosis symptoms and examined by X-ray radiographs. One worker was diagnosed with tuberculosis, but the sputum culture result was negative, and no strain was obtained. The purified protein derivative (PPD) skin tests of 10224 dairy cows showed that 99 cows were positive, with a positive rate of 9.7‰. The Oesophageal-Pharyngeal (OP) secretions of PPD-positive cows were cultured, and 21 strains were obtained. After amplifying and sequencing the 16SrDNA, hsp65 and rpoB genes and the ITS region, sequence alignment in BLAST showed that these strains were nontuberculous mycobacteria (NTM)(18 Mycobacterium nonchromogenicum , 1 Mycobacterium hiberniae , 1 Mycobacterium arupense and 1 Mycobacterium chitae ).Conclusion This study indicated that PPD-positive cows on dairy farms were infected with NTM rather than Mycobacterium bovis . Cross-infection of tuberculosis between humans and cows on dairy farms has been controlled.

First-degree and second-degree stochastic dominance were used to separate a panel of 112 dairy farms with ten annual observations per farm into successful and less successful groups using four different performance measures. Logit regression using 16 independent variables was then used to determine important farm characteristics leading to farm success. High milk production and controlling hired labor and purchased feed expenses were important. The selective adoption of new technologies was also important. Optimal debt-asset ratios varied over the 10-year period.
