Guinea’s current EAS system has been underfunded and underutilized, and the government and donors are working together to improve EAS delivery. This report, produced by Feed the Future’s Developing Local Extension Capacity (DLEC) project reviews Guinea’s EAS system to recommend areas for potential investment by government, donors, nongovernmental organizations (NGOs) and the private sector and will serve to guide investors in EAS. Evidence generated from this desk review will contribute to the knowledge base for best-fit practices to build up EAS in Guinea. The modified DLEC best-fit conceptual framework that appears below guides the DLEC project overall and this report.
