Effect of Climate Change on Philippine Agriculture

The vulnerability of Philippine agriculture to climate change has been acknowledged to be substantial. Government policies have been pushed through to be able to cope up with the demands of climate change. This paper seeks to determine the impact of climate change to the agriculture sector of the country. This study finds that lag of temperature change has an inverse relationship with the change in output. Based on the data - results show that gross production value of Philippine agriculture decreases by 19.21 when there is a 1C increase in temperature. The same is true with precipitation gross production value in agriculture would decrease by.24 for every 1 mm increase in precipitation but more number of rain days would increase gross production value by 1.24. An increase in Diurnal range temperature as measured by the difference between the daily maximum and minimum temperature would decrease gross production value by 5.74. This paper also supports the idea that the agriculture sector of the Philippines as a tropical country, is rain-fed and that a drier season would decrease agricultural output.
