In this scenario, the project manager should engage with all stakeholders, including the farmers' group, to discuss the project objectives and review their requirements. This is in line with the best practices of stakeholder engagement and management, which are critical for the success of any project. By involving the farmers' group, the project manager can understand their needs and concerns, and work towards a solution that accommodates all parties involved. This approach not only helps in mitigating risks but also ensures that the project delivers value to all stakeholders.
