The objective of the literature review is to provide partners with information to help them frame the SASAS project in Sudan. It is solely a desk review on recent literature, scientific journals as well as project documents and popular press gathering data about last mile in Sudan and other comparable locations. The overarching goal is to build on both good and negative lessons acquired to avoid repeating unsuccessful strategies or duplicating work that has previously been done. Sudan and other African countries providing best practices are being examined in this review. In addition, best practices and lessons learnt from other states in relation to last mile are included in this section. This review was conducted prior to the April 15th, 2023, events.
