This article examines the economics of Africa's emerging air cargo supply chains, taking floriculture as a case study. Floriculture is an important employer, and earner of foreign exchange for several regions of central/southern and eastern Africa including more recently Ethiopia. Air transportation often plays a critical role when the supply-chain involves high-value, non-durable, relatively light-weight, and compact consignments such as flowers, and geographically when regions are difficult to access by other trunk modes. The success of air cargo chains, however, depend as much on the quality of surface modes serving various "last mile" access and egress functions, as well as efficient nodal interchange points and the availability of suitable airport and airline capacity. The last, because of the important role of belly-hold space, includes consideration of passenger as well as cargo specific services. To meet the needs of Africa's floriculture sector, a variety of supply-chain models have emerged that embrace air and surface links, as well as storage at various points in the chain. The paper considers the nature of these chains, the for their structures and their limitations.
本文以花卉种植为例,研究了非洲新兴航空货运供应链的经济情况。花卉种植是包括埃塞俄比亚在内的非洲中南部和东部几个地区的重要雇主和外汇收入来源。当供应链涉及高价值、非耐用、相对轻质且紧凑的货物(如鲜花)时,以及当某些地区难以通过其他干线运输方式到达时,航空运输通常起着关键作用。然而,航空货运链的成功同样取决于服务于各种“最后一英里”进出功能的地面运输方式的质量,以及高效的节点换乘点和合适的机场及航空公司运力的可用性。最后一点,由于腹舱空间的重要作用,这包括对客运和货运特定服务的考量。为满足非洲花卉种植部门的需求,已经出现了多种包含航空和地面连接以及链上各点存储的供应链模式。本文探讨了这些供应链的性质、其结构的成因及其局限性。
