Competition Use of Cassava for Food and Fuel in Thailand : An Economic Assessment
Abstract:
Cassava is one of the most important crops in Thailand as it is one of the most
feasible feedstock for ethanol production to help meet the target set by the Alternative
Energy Development Planning (AEDP) of 9 million liters per day by the year 2022. That
target is very ambitious and will need a considerable amount of feed stock to supply
ethanol production. So this paper aims to study factors affecting the demand, supply, and
price of cassava in Thailand for both food and fuel and to observe it's effect on ethanol
production targets.
The analysis utilized time-series data for the period 1989-2009 in order to estimate
the model parameters by means of the Two-Stage Least Squares (2SLS) method. Factors
affecting supply of fresh cassava are the yield and the land area cultivated. The cultivated
land utilized is also affected by the lagged of both land area cultivated and the price of
cassava roots. On the demand side, cassava products such as chips, pellets, and starch are
affected by their wholesale price, competitor's price and policy implementation. Factors
affecting cassava root price are the wholesale price which itself is affected by the supply
whereas factors affecting cassava product price are it's export price, cassava root price and
policy implementation
The results of this analysis found that in recent years the share of ethanol for
transport has been increasing continuously. As a result, a larger share of ethanol was made
from cassava. However, this study found this increase of demand for cassava had no
significant effect on cassava price variation. This is because this consumption of cassava
for ethanol production was less than 0.2% of the total cassava production (2009).
Then the model was used for forecasting to assess the impacts of the increased
demand for ethanol production for vehicles to meet the Thai government's target on
cassava market year 2010-2030. The results indicate that the increasing demand of cassava
for ethanol feedstock contributes to increase in cassava demand and also increase in
cassava prices while the supply side is increasing according to the growth of cassava
production yield with limited plantation area. That makes the farmers happy with a high
price but the cassava entrepreneurs might not appreciate a higher feedstock cost. Ethanol
production cost is more expensive than the ex-refinery price of gasoline octane 95, and to
be competitive with the gasoline, government must continue to subsidize ethanol. However
the government's expenditure for ethanol subsidy is lower than the benefits fiom this
policy; energy security, better air quality and the supplement to farmer's income through
increases in cassava prices.
Without cassava use for ethanol fuel the cassava price still is increasing according
to the demand fiom China, but the growth is lower than when the ethanol policy is
implemented.
