The path to scaling early warning and rapid response system for pests and diseases: insights from Ghana

The increasing threat of pests and diseases poses significant challenges to agricultural productivity and food security in Ghana. This brief on the Early Warning and Rapid Response System for Pests and Diseases (EWRRS-PD) developed through efforts under the Accelerating Impact of CGIAR Climate Research in Africa (AICCRA) aims to provide a comprehensive pathway for designing and scaling the system, recognizing the key roles of strategic stakeholders involved in pest management – farmers, agricultural extension workers, policymakers, and researchers. The EWRRS-PD is designed to enhance the capacity for early detection and prompt response to pest outbreaks, thereby mitigating potential losses in crop yields and safeguarding livelihoods (Honger et al, 2023; Osae et al., 2024). In Ghana, the interplay of climate change, trade dynamics, and socio-economic factors has intensified the spread of agricultural pests and diseases. By leveraging innovative technologies such as on-ground detection networks, satellite data, and predictive modelling, the EWRRS-PD facilitates timely alerts and actionable information to prevent and combat these threats effectively. The collaborative efforts outlined in this brief emphasize the importance of stakeholder engagement, data sharing, and integrated pest management strategies to foster resilience within the agricultural sector. This brief serves not only as a guide for developing an impactful EWRRS-PD but also present an example of how the system can function. Besides, it is a call to action for all stakeholders to commit to proactive measures that ensure sustainable agricultural practices in Ghana and beyond. By strengthening our response mechanisms and enhancing communication channels, we can work together towards a more secure and productive agrifood systems in current and future contexts.
