The CLARISSA project seeks to tackle child labor in Bangladesh and Nepal. What is unique about it is that it involves the active participation of the affected children themselves in exercises to reflect on the causes and the development of causal pathways. These ToC development processes by the children effectively become part of the intervention in their own right.
The CLARISSA website: https://clarissa.global, which has many resources on the project.

AgriProFocus is a network that offers a central ‘marketplace’ where organisations, professionals, resources and knowledge come together. Professionals that make up the network decide to cooperate in one of the AgriHubs or on one of several knowledge themes. The AgriHubs are local networks set up in nine African countries, which provide multiactor arenas in support of entrepreneurship. A constant flow of information and power to connect is at their heart. The visual ToC shows how the hubs are expected to contribute to effective market uptake, which ultimately will improve farmer enterprise performance. The visual dates from 2012.
