What happened
Mixed outcomes. In the systems examined, farmer-managed irrigation had higher average performance and stronger local rule enforcement than agency-managed irrigation. The comparison points to the importance of organization alongside infrastructure. Differences in water availability, geography, and system size make it difficult to attribute the whole advantage to local management.
- Farmer-managed systems tended to outperform state-operated systems despite comparatively low-tech infrastructure. The Performance of Self-Governing Irrigation Systems in Nepal
- Enforcement was stronger in the farmer-managed systems with locally devised rules than in the agency-managed systems with rules made by outside officials. Rules and collective action: an institutional analysis of the performance of irrigation systems in Nepal
- The rules operated in communities with different beliefs and biophysical conditions; management type alone did not describe all the conditions affecting cooperation. Rules and collective action: an institutional analysis of the performance of irrigation systems in Nepal
What might explain it
Supported in case
Locally workable rules and credible enforcement helped sustain contributions and coordination. Rules and collective action: an institutional analysis of the performance of irrigation systems in Nepal
Alternative explanation: Water availability, system size, geography, and selection into management type could explain part of the performance difference.
Plausible
Infrastructure projects can disappoint when they alter physical works without preserving users' incentives to maintain and allocate water.

Alternative explanation: Insufficient funding, staff, or maintenance quality within agencies may matter more than external rulemaking itself.

Local management still needs to handle water flows, infrastructure, and disputes beyond an individual community. Strong local organization and public technical support can serve different parts of the same system.
Questions to take into practice
- Upgrading physical works can leave water delivery unreliable if maintenance and allocation responsibilities no longer fit users' incentives.
- Rules written by an agency and rules people actually enforce can describe different operating systems.
- Average performance can conceal different outcomes for users near the water source and those at the tail end.
What remains uncertain
- The systems were not randomly assigned to management arrangements, so geography, water supply, and prior community organization may explain some of the observed difference.
- The distribution of gains between head-end and tail-end users remains important even where average system performance is higher.
