Productivity of rice farming in the Philippines: Patterns and sources

Abstract

The uncertainty in the world market and the increasing reliance of the Philippines in rice imports compel the government to increase domestic production. Knowing the patterns and sources of rice production growth in the recent years can provide insights to alternative ways of increasing rice production in immediate future. This study examined the sources of rice production growth in the Philippines from 1996 to 2007. A translog production function was estimated using a generalized instrumental variable estimator. Using this framework, the contributions to production growth of conventional and non-conventional inputs were separated from the growth in residual total factor productivity.

Higher output growth was observed during wet and dry season of 2001-2006 and 2002-2007 compared to that of 1996-2001 and 1997-2002. Wet season rice production grew by 22% from 2001 to 2006, of which 15% and 6% were sourced from increase in uses of conventional and non-conventional inputs, respectively. Similarly, rice production during dry seasons from 2002 to 2007 rose by 14%, of which 10% was due to expanded use of non-convention inputs. Residual total factor productivity contributed nearly 4% while conventional inputs contributed minimally during the dry season. Thus, uses of non-conventional inputs such as irrigation, hybrid and third generation modern inbred rice varieties, certified seed, training, and machine ownership have been central to production growth in both wet and dry seasons from 2001 to 2007.
