The analysis of social networks can contribute to the concrete implementation of these policies, by precisely identifying which actors are best able to disseminate new practices within their network. In commerce, women form a group whose social capital must be promoted. The example of the rice sector shows that women's education, work experience and income levels are significantly lower than men. The analysis also shows that the centrality of women within networks is lower than that of men regardless of the measure adopted, which is explained by their relegation to low-paying segments of the value chain.
