| Description: | A rapid development in economic sectors has induced the water depletion in most of the developing country, particularly for Malaysia. This study estimates the water footprint of rice cultivation in 11 states in Peninsular Malaysia. The latter part was focused on the derivation of new water stress indices (WSI) of selected main watersheds in Peninsular Malaysia from a period of 10 years (2005 - 2014). These water stress indices were then used to evaluate the potential of water deprivation of rice cultivation. The water footprint for cultivating rice was determined based on the CROPWAT 8.0 and Penman Monteith model. CROPWAT 8.0 model was used to compute the evapotranspiration and crop water requirement (effective rainfall and irrigation requirement) of the rice grown in Peninsular Malaysia from 2005 - 2013 (9 years). It was found that the water footprint for cultivating rice for both main and off seasons range between 1600 m3/ton to 2800 m3/ton and 1600 m3/ton to 3300 m3/ton, respectively. The results of this study indicate that for both seasons, green water footprint for 11 states is higher than blue water footprint. The extreme water stress index was found for Penang and the average water stress index for Peninsular Malaysia is 0.08. Water deprivation for 11 states was calculated by multiplying the blue water consumption with water stress index and the total water deprivation is 6,948 m3H2Oeq/year. In conclusion, water consumption for rice cultivation is higher compared to other agricultural crops and this will accelerate the competition on the consumption of clean water with the other sectors. However, the availability of water resource in Peninsular Malaysia is sufficient to fulfill the demands for water at the present time.,“Certification of Masters/Doctoral Thesis” is not available,Masters Of Science |
