This article describes the impact of implementing an environmental problem solving approach by three groups of students from the Republic of Guinea. The objective was to better understand the issues stemming from such an approach with regard to citizen engagement of young Africans towards sustainable development. One classroom from elementary school, one form secondary school and one from a vocational school worked to lay down and formulate solutions to the problem of water quality in the country capital, Conakry. The data collected showed students' interests towards these questions, especially when they are apprehended by direct observation in the field; their desire to take action was also evident. The main limitations observed are the limited access to documentary resources as well as the lack of training of teachers in environmental and sustainable development education.
