Background: Administration of antimicrobials to food-producing animals is regarded as a major contributor to the overall emergence of resistance in bacteria worldwide. However, few data are available on global antimicrobial use and resistance (AMR) in livestock, especially from low- and middle-income countries. Methods: We conducted a structured survey of 91 small-scale pig farms in the urban and peri-urban areas of Phnom Penh, Cambodia, to assess the farmers’ knowledge, attitudes and practices related to antimicrobial use in their pig production. Commensal Escherichia coli was isolated from three healthy pigs from each farm (n = 261) and susceptibility testing was performed against 14 antimicrobials, using broth microdilution. Univariable logistic regression and generalized linear mixed models were used to investigate potential associations between farm characteristics, management factors and resistance to different types of antimicrobials. Results: We found a widespread and arbitrary use of antimicrobials, often based on the farmer’s own judgment. Around 66% of the farmers reported frequently self-adjusting treatment duration and dosage, and 45% had not heard about the term ‘antimicrobial resistance’. The antimicrobials most commonly mentioned or kept by the farmers were amoxicillin, tylosin, gentamicin and colistin. Around 37% used a feed concentrate that contained antimicrobials, while antimicrobials for humans were used as a last-line treatment by 10% of the farmers. Commensal E. coli exhibited high prevalence of resistance to several antimicrobials considered to be of critical importance for human medicine, including ampicillin, ciprofloxacin and colistin, and multidrug-resistance was found in 79% of the samples. Higher prevalence of resistance was observed on farms that administered prophylactic antimicrobials and on farms that treated the entire group or herd in the event of disease. Conclusion: The widespread and arbitrary use of antimicrobials in pig farming in Cambodia is highly worrisome. Overall, farmers had a low awareness of the risks and consequences related to antimicrobial use and AMR. The results presented in this study confirm the hypothesis that non-rational use of antimicrobials results in higher prevalence of AMR and highlight the need for professional animal health systems that involve medically rational use of antimicrobials in emerging economies such as Cambodia.

In the next 24 years, the Malawian population is expected to double, a development that will inevitably affect access to land and land holding sizes. As access to land is already limited, securing food for the growing population will require policy shifts including the promotion of agricultural intensification. Malawi’s economy depends on the agricultural sector, and this paper addresses the generational perspective of agricultural intensification, with specific focus on youth and elderly in smallholder production systems. Despite wide recognition that an overwhelmingly large share of the Malawian population is young, our research finds that the younger generation have less access to land than the older generations. The elderly are limited in farming due to the physical labour required for agriculture, yet they withhold their pieces of land. Our research shows that maize yields have remained low between 2008 and 2017, and that the elderly have had the lowest yields. The potential for sustainable agricultural intensification therefore remains low until access to land and financial support for the youth receive special attention in all relevant circles including policy discourses. The paper situates the findings from this study within the broader scholarship on generational changes and perceptions in relation to access to resources for production.

Livestock manure is a valuable source of nutrients for crop production, but can also pose a public health hazard and have negative environmental impacts. This study investigated manure management practices among urban and peri-urban livestock keepers in Cambodia, to identify risk behaviours and socio-economic aspects associated with the handling of manure. A survey including 204 households was conducted, using a structured questionnaire with questions on demographics, socio-economic characteristics and household practices related to manure management. Faecal samples were obtained from pig pens and pig manure storage units for analysis of the potential zoonotic pathogens Salmonella enterica (Polymerase Chain Reaction (PCR)), Ascaris suum and Trichuris suis (McMaster flotation technique). The survey revealed a difference in management between cattle and pig manure. Cattle manure was most commonly used as fertiliser for crop production (66%) (p<0.001), whereas pig manure was most commonly dumped in the environment (46%) (p<0.001). Logistic regression models showed that households with a lower socio-economic position were more likely to dump pig manure (p<0.001), with scarcity of agricultural land (p<0.001) and lack of carts for transportation of manure (p<0.01) being identified as contributing factors. Salmonella enterica was detected in 9.7% of manure samples, while Ascaris suum and Trichuris suis were detected in 1.6% and 2.4% of the samples, respectively. The results presented in this study indicate that manure management by urban and peri-urban households may pose a public health threat and an environmental hazard. There is evidently a need for further knowledge support to the livestock keepers to promote good management practices.

This article explores the phenomenon of in-kind remittances of maize and its implications for rural household livelihoods and food consumption. Interviews with a sample of 391 households in eight villages in Malawi are used to substantiate the discussion. Explanations for in-kind remittances are sought in the micro-level interaction between the formal market realm, informalised exchange systems and the household. Remittances are not connected to lower commercialisation levels, suggesting that the explanation for remittances should be sought in the production and consumption patterns of the households. Remittances function as an important redistributive mechanism for food across space. The role of smallholder food production for urban livelihoods as well as the subsistence responsibilities of rural households are underestimated if agrarian household level linkages from rural to urban areas are not recognised in national production and consumption surveys and among policy makers.

Using longitudinal data from 2354 smallholder households in 103 villages in eight African countries, three processes of agrarian transformation are analysed for the period 2002 to 2008: intensification of grain production, commercial diversification from staple crops and income diversification out of agriculture. Methodologically, three multi-level, binary logistic models are used. The trends observed provide grounds for some optimism: despite an overall picture of stagnation, intensification in grains (yield per hectare) seems to be increasing. Farmers have, however, raised productivity through the more intense use of labour resources rather than through technological change, while political commitments to agriculture have not improved the production environment. Rather, economic growth and commercialization emerge as strong drivers of intensification, both at country and household levels. Tendencies towards distress-driven income diversification out of agriculture appear to have abated somewhat in the face of more dynamism in the grain sector, with households moving between the farm and non-farm sectors in response to shifts in producer incentives and non-farm opportunities. Diversification processes within agriculture, meanwhile, point to both push- and pull-driven diversification occurring simultaneously. Grain markets, crop diversification and non-farm opportunities complement one another over time. There is little evidence of even incipient processes of structural transformation among the smallholders surveyed.
