RESUMEN

Small-scale farmers are essential food suppliers, especially in developing countries, but they face many constraints that limit their productivity and returns. Associating with other farmers (for instance, through cooperatives) has been shown to be a strategy to mitigate these constraints; however, there are limitations in farmers' participation and commitment to associations. This research explored small-scale farmers' attitudes and perceptions of associations. This paper considered the district of Cauquenes, a rural area in central Chile. A total of 71 small-scale farmers were surveyed. The data were processed using descriptive, multivariate, and qualitative techniques. The results showed that the farmers had limited knowledge of and experience with associations. They also did not see participation in an association as necessary for improving their business outcomes. They were also reluctant to accept a possible loss in decision-making power or the possibility of being scammed or tricked. The factors underlying farmers' attitudes toward associations were "Uncertainty of economic benefits" (23.3% of variance), "Technical-economic limitations perception" (15.2%), "Distrust" (10.8%), and "Individualism" (9.8%). These results suggested that policies are needed to improve farmers' experience with and knowledge of associations, considering the cultural variables that affect distrust and focusing on existing uncertainties. The associative processes need to allow for progressive commitment, expedite tangible results, and provide continuous technical and motivational support.


Os pequenos agricultores são essenciais para o abastecimento de alimentos, especialmente nos países em desenvolvimento, mas enfrentam muitas restrições que limitam sua produtividade e retorno. A associação com outros agricultores (por exemplo, por cooperativas) tem se mostrado uma estratégia para mitigar essas deficiências, no entanto, há entraves na participação e comprometimento dos agricultores com as associações. O objetivo desta pesquisa é explorar as atitudes e percepções dos pequenos agricultores em relação às associações. Para isso, consideramos o caso do distrito de Cauquenes, uma área rural no centro do Chile, em que se entrevistou um total de 71 pequenos agricultores. Os dados foram processados por meio de técnicas descritivas, multivariadas e qualitativas. Como resultados, os agricultores têm um conhecimento e experiência limitados sobre as associações e, além disso, não entendem a relevância do vínculo social como uma alternativa para melhorar o seu desempenho. Por outro lado, relutam em uma possível perda de poder decisório, bem como em serem enganados. Os fatores subjacentes às atitudes dos agricultores em relação às associações foram "incerteza dos benefícios econômicos" (23,3%), "percepção de limitações técnico-econômicas" (15,2%), "desconfiança" (10,8%) e "individualismo" (9,8%). Esses resultados nos demonstram serem necessárias políticas que promovam o conhecimento direto, concreto e experiencial dos agricultores sobre o associativismo, com foco nas incertezas existentes. Os processos associativos devem estar atrelados a compromissos progressivos, com foco em resultados tangíveis e suporte contínuo, não apenas técnico, mas também motivacional.

RESUMEN

Nontuberculous mycobacteria (NTM) are ubiquitous microorganisms naturally resistant to antibiotics and disinfectants that can colonize drinking water supply systems. Information regarding the spread of NTM in specifically South America and Colombia is limited. We aimed to identify and characterize NTM present in tap water samples from Cali, Colombia. Drinking water samples and faucet biofilm swabs were collected in 18 places, including the city's three main water treatment plants (WTPs). Filter-trapped material and eluates (0.45 µm) from swab washes were plated in 7H11 agar plates. Suspected colonies were evaluated microscopically, and NTM species were identified based on the rpoB gene. Antibiotic susceptibility testing was also performed. Fifty percent (9/18) of sampling points were positive for NTM (including two WTPs), from which 16 different isolates were identified: Mycobacterium mucogenicum (8/16), M. phocaicum (3/16), M. chelonae (2/16), M. mageritense (2/16), and M. fortuitum (1/16), all rapidly growing mycobacteria. A susceptibility profile was obtained from 68.75% (11/16) of the isolates. M. chelonae was the most resistant species. All NTM isolated are potentially responsible for human diseases; our findings might provide a baseline for exploring NTM transmission dynamics and clinical characterization, as well as potential associations between NTM species found in drinking water and isolates from patients.
