“…The water footprint of rice has so far been conducted by focusing on the volumetric water consumption of rice cultivation in various countries as the virtual water footprint [21][22][23]. The results revealed that although the water footprint of rice in Asia is high, the contribution to water scarcity is relatively low because the rice is generally grown in the wet season (rainfed paddy field) and rainwater is the major water source.…”

Rice cultivation is a vital economic sector of many countries in Asia, including Thailand, with the well-being of people relying significantly on selling rice commodities. Water-intensive rice cultivation is facing the challenge of water scarcity. The study assessed the volumetric freshwater use and water scarcity footprint of the major and second rice cultivation systems in the Chao Phraya, Tha Chin, Mun, and Chi watersheds of Thailand. The results revealed that a wide range of freshwater use, i.e., 0.9-3.0 m 3 /kg of major rice and 0.9-2.3 m 3 /kg of second rice, and a high water use of rice was found among the watersheds in the northeastern region, like the Mun and Chi watersheds. However, the water scarcity footprint results showed that the second rice cultivation in watersheds, like in Chao Phraya and Tha Chin in the central region, need to be focused for improving the irrigation water use efficiency. The alternate wetting and drying (AWD) method was found to be a promising approach for substituting the pre-germinated seed broadcasting system to enhance the water use efficiency of second rice cultivation in the central region. Recommendations vis-à-vis the use of the water stress index as a tool for agricultural zoning policy were also discussed.

“…Gray water footprint has been left out from most studies due to its different focus on the aspect of water quality, instead of the aspect of quantity that is commonly asssessed based on the total water withrawal. Gheewala et al [15], Wang et al [19], and Marano and Filippi [16] have quantified the water footprint of rice cultivation for the green and blue water footprints with an exclusion of gray water footprint as their studies focused more onto water balance rather than water footprint. The present study only focused on the green and blue water footprints in order to quantify potential water deprivation in Malaysia.…”

“…This implies that the water footprint analysis depends not only on the volume of water use but also on where and when the water is consumed ). Many studies have been carried out to assess the water footprint of crops [4,[8][9][10][12][13][14][15][16][17][18][19][20]. However, this methodological approach is still new and under development in Malaysia.…”

a b s t r a c tRecent years have seen a surge of interest in assessing water withdrawal in the agricultural sector which has been experiencing an increasing concern with sustainable environmental requirements. Like other highly water-intensive crops, rice production systems rely on an ample water supply, thus posing a serious threat to water availability. This study estimates the water use of rice cultivated in the off-and main seasons in Malaysia. The water withdrawal of rice was estimated based on the monthly climatic data of 30 y (1983-2013) and a 10-y (2002-2011) average annual crop yield. The water stress index (WSI) of the 16 major watersheds in Malaysia was also derived to assess the water deprivation. We found that the blue water use for rice cultivation in the off-and main seasons ranges between 619 and 1,421 m 3 /t and 504 and 1,031 m 3 /t, respectively. The results also showed that the average WSI for 11 states in Peninsular Malaysia is 0.08 with a total water deprivation of 97 million m 3 H 2 O eq/y. This study can serve as baseline information for the government in identifying the areas that need to be conserved and the recommendations that should be drawn toward sustainable management of water resources in Malaysia.

“…WFs within the agricultural sector have been extensively studied. Most studies were mainly focusing on the WF of crop production, at scales from an irrigation district [9][10][11], a city level region [11][12][13][14][15][16][17], a river basin [12,[18][19][20][21][22], and a country [23][24][25][26][27][28][29][30], to the global perspective [31][32][33][34][35]. Among previous studies, Gobin et al [36] conducted a calibrated model on wheat, barley, grain maize, oilseed rape, potato and sugar beet.…”

Rapid economic development has posed pressure on water resources, and the potential for a water crisis has become an important obstacle to the sustainable development of society. Water footprint theory and its applications in agriculture provide an important strategic basis for the rational utilization and sustainable development of water resources. Based on the monthly meteorological observations and agricultural data of Shandong Province, CROPWAT 8.0 and Geographic Information System (GIS) technology, the green, blue and grey water footprints of wheat, maize, cotton and groundnut from 1989 to 2016 were calculated and the spatial variations of water footprints for crops in different rainfall years were analyzed. Additionally, assessment of water stress for agricultural productions was conducted in this study. The results showed that the average water footprints of wheat, maize, cotton and groundnut were 2.02 m3/kg, 1.24 m3/kg, 7.29 m3/kg and 1.75 m3/kg, respectively in Shandong Province. A large amount of the average total water footprint was calculated for wheat (420.59 × 108 m3/yr), maize (222.16 × 108 m3/yr), cotton (72.70 × 108 m3/yr) and groundnut (50.07 × 108 m3/yr). The average total water footprint of the four crops was 765.52 × 108 m3/yr (29.98% blue) and exhibited a gradual decreasing trend over time. Specifically, the total water footprint of wheat was the highest among four main crops in Shandong Province and exhibited a decreasing trend during 1989–2016. The maize was ranked in the second place, and was the only crop still increasing rapidly. The spatial and temporal changes of water footprints for crops were obvious in different rainfall years. Additionally, agricultural productions in most regions were facing the threat of water scarcity. Therefore, the scientific planning of crop planting structures and rational control of sown areas of crops with large water footprints should be implemented in severely water-scarce regions. This study can give some suggestions on the adjustment of planting structure for the sustainable development of agriculture and the realization of efficient utilization of water resources.
