A systematic review of the impact of post-harvest aquatic food processing technology on gender equality and social justice

Post-harvest practices and technologies are key to reducing global aquatic harvest loss. The lives of post-harvest fisheries workers, over half of them women, are deeply affected by these technologies, but their equity and equality outcomes are poorly understood. This systematic review synthesizes evidence of post-harvest aquatic food processing technology outcomes, showing that persistent inequalities in social structure and norms disadvantage women across a range of technologies, both traditional and improved, especially regarding control over resources. We found that improved technologies bring enhanced productivity and possibly income for workers, yet contracts are often precarious due to pre-existing social inequities. While power and control of resources is more unequal in factory settings, it is not necessarily equal in traditional contexts either, despite offering greater flexibility. More rigorous comparative research, including voices of diverse actors, is key to understanding the impacts of different technologies on gender equality and social justice and inform policymaking. Fisheries and aquaculture production are key to livelihoods, food and nutrition, yet over one-third of global aquatic harvest is lost or wasted. The post-harvest sector, key to reducing these losses, and dominated by women workers, is not well understood. This systematic review synthesizes evidence on equity and equality outcomes of post-harvest practices and technologies that aim to reduce loss and waste in the fisheries sector.
