Do the most promising policies to promote sustainable upland farming originate at the local or national level? Will coordination of local and national efforts produce better outcomes? This paper uses an optimization-simulation model of the Manupali watershed in the Philippines to investigate...

Approximately 90 percent of the world's production and consumption of rice occurs in Asia, and regional demand is projected to increase by 70 percent over the next 30 years. Meeting this demand requires an expansion of the total area under irrigation in the coming decades. In this article, the...

We estimate a random effects stochastic frontier production function to study the impacts of irrigation on factor use on low-income rice farms in the Philippines. Irrigation precipitates a release of labor and an increase in use of fertilizer and pesticides. We find only weak statistical support...
