The incorporation of PIM in a local community provides more opportunities to advance both individual and community learning among relevant parties. The lessons learned demonstrate the inherent potential of marginalized Thai farmers, who are capable of directing their own water service delivery. The lessons also illustrate the proper role of public irrigation staff as organizers who arrange the ideal conditions for promoting the authentic dialogue in PIM discussion, thus facilitating mutual learning among stakeholders. Opportunities from PIM help reinforce the recognition of being valuable persons in the local communities of marginalized Thai farmers and, moreover, become the strengthened foundation of Thai society that is able to endure the growing challenge.
