[Excerpt] ICF Macro carried out a mixed-methods research study to gather exploratory data on the causes and consequences of child labor and forced child labor in the fishing industry in Uganda through the Supply Chain Methodology (SCM) developed under a phase of methodology development prior to the launch of research. SCM is based on the application of social network theory to the economic concept of the supply chain. Specifically, under SCM, all forms of objectionable labor are also viewed as economic activities producing goods or services. Since goods and services follow a supply chain from the source of initial materials or people to an endpoint serving a customer, the supply chain is thus considered a type of social network. By mapping this special type of network, research can identify where various kinds of labor, including egregious forms such as child labor, are used in the network. This information can inform the research design and help develop a better understanding of locations, worker populations and work conditions. Applying this methodology, ICF Macro aimed to collect data on the characteristics, nature, and incidence of child work, as well as instances of forced child labor in the fishing sector in Uganda.
