220 investment in the water system moderately increases by USD 2.9 billion, accounting for 8% of the total investment This is an increase of USD 1.51 billion and USD billion more than in SC1 and SC2, respectively At the same time, in a continuation of the historical development strategy in other socio-economic sectors, major investment is likely to be allocated to the power sector, which constitutes 92.1% (USD 31.2 billion), although it is moderately lower by USD 13.7 billion than in SC2 The investment in the power system in SC4 is, therefore, USD 2.4 billion and USD 3.7 billion higher than in SC1 and SC3, respectively Investment in transportation systems in SC4 is expected to increase annually to USD 1.1 billion, accounting for 3.2% of the total infrastructure investment, which is slightly higher than in the other scenarios in terms of absolute value: USD 80 million, USD 350 million, and USD 120 million more than in SC1, SC2, and SC3, respectively Overall, this result indicates that a water-oriented policy could generate a considerable positive impact among the non-nexus approach scenarios For example, SC4 generates the highest economic output with GDP at USD 385 billion, while requiring a marginally higher investment compared with SC1 and SC2 and a moderately lower investment compared with SC2 The result is a strong increase in value in the water sector The SC5 Food–Water–Energy scenario presents the second-highest investment in infrastructure among the various scenarios, reaching USD 58 billion in 2030 This is USD 26.8 billion, USD 11.5 billion, USD 28 billion, and USD 23 billion more than in SC1, SC2, SC3, and SC4, respectively Similar to the other scenarios, among the portfolios of infrastructure investment, the power system accounts for the highest proportion at nearly 97% (over USD 56 billion), which is USD 27.4 billion, USD 11.3 billion, USD 28.7 billion, and over USD 25 billion more than in SC1, SC3 and SC4, respectively Investment in water systems accounts for 1.9% of the total investment, reaching USD billion; however, this is relatively lower than in the other scenarios For example, it is USD 240 million, USD 260 million, and USD 380 million less compared with SC1, SC3, and SC4, respectively, while being USD 250 million more than in SC2 Finally, investment in transportation systems is forecasted to constitute 1.3% of the total investment, reaching USD 0.7 billion This amount would, therefore, account for the lowest proportion compared with the other scenarios In other words, it is 29% (USD 300 million), 4.5% (USD 30 million), 26% (USD 260 million), and 34.5% (USD 370 million) lower than in SC1, SC2, SC3, and SC4, respectively (as shown in Figure 6-35 and Figure
