The unprecedented impact of the pandemic on both activities and profit of actors draws out the various areas of the value chain that need to be strengthened to ensure resilience in the face of global shock. This study fills the gap by assessing the extent at which COVID-19 impacted the profit of mango value chain actors in southern Ghana. It also analyzed the governance structure and the existing linkages in the dissemination of market information in relation to the profit of the actors. A two-year panel survey on 240 respondents was conducted in 2020 through a multi-stage sampling technique in Greater Accra, Eastern and Volta regions of Ghana. Net Farm Income, Social Network Analysis and Difference-in-Difference models were used in analyzing the data. Findings revealed that mango processors have more bargaining power and make the most profit while producers receive more information than other actors. Farmer-based organizations were found to be the prominent node and influential in the dissemination of market information within the value chain. The outbreak of COVID-19 negatively impacted the profit of mango producers and distributors; however, processors had a positive impact on their profit. The study therefore demonstrated that producers and distributors were vulnerable to the effect of the COVID-19 shock, whilst processors were robust to the shocks. Thus, reformed policies by all stakeholders for emergency preparedness should be targeted especially at those vulnerable actors in the chain. Additionally, FBOs, retailers and other key stakeholders should be considered in policy development to enhance market information dissemination.
疫情对演员活动和利润的空前影响，凸显出需要加强价值链的各个领域，以确保在全球冲击面前具有弹性。本研究通过评估 COVID-19 对加纳南部芒果价值链参与者利润的影响程度，填补了这一空白。它还分析了治理结构和现有市场信息传播的联系，以评估参与者的利润。2020 年，通过在加纳大阿克拉、东部和沃尔特地区的多阶段抽样技术，对 240 名受访者进行了为期两年的小组调查。净农场收入、社会网络分析和差异分析模型用于分析数据。调查结果显示，芒果加工商拥有更多的议价能力，获得了最大的利润，而生产者比其他参与者获得了更多的信息。农民组织被发现是价值链中传播市场信息的突出节点和有影响力的节点。COVID-19 的爆发对芒果生产者和分销商的利润产生了负面影响，但对加工商的利润产生了积极影响。因此，所有利益相关者都应制定改革政策，以做好应急准备，特别是针对该链中易受影响的参与者。此外，应考虑农民组织、零售商和其他主要利益相关者，以加强市场信息传播。
