The Algerian civil war, 1992–2002, affected all aspects of life in the country. Major development efforts were therefore initiated in the post-conflict era. Almost 20 years later, the economy remains fragile, and the country’s large hydrocarbon revenues have not been used to develop the infrastructure for sustainability, support energy transition or reduce structural vulnerabilities. This paper provides an overview of Algerian development strategies before and after the conflict, examining in particular the orientation of major development projects involving foreign financing. Two rural development programmes are described to illustrate the outcomes of such projects. The results show that the conflict stopped or hindered many ongoing and planned development projects in the country, especially in the agriculture sector, while new investments in industry started after the conflict. The review of individual development projects further revealed that many projects between 1980–2017 had doubtful benefits with respect to long-term development goals. Initiatives tended to be discontinued once the funding period closed, and the involvement of the private sector was low. It is therefore concluded that additional attention needs to be devoted to long-term and structural impacts of development projects, including considerations regarding sustainability, demographics, and climate-related future changes.
