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 value chain analysis 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. Greater Khartoum, Blue Nile, and South Kordofan are the states being examined in this review. Priority crops in this review include groundnut, sesame, sorghum, wheat, millet, soybean, vegetables/horticulture. Livestock value chains were also part of this review. In addition, best practices and lessons learnt from other states in relation to value chain analysis are included in this section.
