vested annually. In the future for the high-income countries, an investment rate of 0.75% of GDP has been assumed until 2015. For Russia, the OECD (2005b) figure of 0.32% of GDP seems an underestimate, but this has been used nonetheless to 2015. For China, 1.5% has been taken from the Five Year Plan (Section 3) and for India, the figure derived was 0.71%; for Brazil, Almeida and Mulder (2005) give an estimate of only 0.20%, which seems rather low but has been used. The projected GDP growth rates (World Bank, 2005) for EU countries to 2015 are assumed to average 2.3% p.a. overall, with US growth as 2.5% p.a., China 5.3% and India 4.1% p.a. For some countries there may appear to be seemingly high GDP growth rates adopted here. As noted earlier, in adopting broad figures the report has been informed by the available literature, which will tend to underplay individual circumstances. In the particular case of Mexico, for example, given the strong ties with the US economy, it is likely that the country will be influenced by US performance for the foreseeable future, potentially providing support for the projected growth. Fay and Yepes (2005) proposed a general figure of 2% that has been adjusted slightly for middle-income countries, such as Poland and the Czech republic, to 1.9%, in line with the different sectoral allocation of investments between countries. The potential effects of the main drivers that have been reviewed in Sections 3-7 have been considered in relation to each OECD country and others given in Table 5.16. The relative significance of each of the drivers in terms of how they are likely to influence the investment in water infrastructure in the ten-year period to 2015 has been qualitatively evaluated for each country and used to adjust the baseline estimates of proportion of GDP investment over the period. In 2005, the figures are assumed to be those initially defined as above, gradually changing to the adjusted figures by 2015. Beyond 2015, some of the lower- and middle-income countries will have move
