On the other hand, the bottom-up approach advocated by proponents of delegated water management can potentially both be complementary and also conflict with the drive for metropolitan co-ordination inherent in governance reform. This raises two issues for urban water governance: i) re-scaling metropolitan governance may (positively or negatively) affect water governance frameworks, and ii) strategies for metropolitan governance reform may offer interesting models for application in the urban water sector. Evidence from selected OECD metropolitan areas is provided in Table 3.4. The largest functional area, often referred to as the Southeast Region, extends to the Gyeongnam province and Ulsan Metropolitan City. The restricted definition of the functional labour market roughly corresponds with the province of Milan, which includes 189 municipalities induding the city of Milan. The extended definition of the functional area includes the province of Milan and seven other provinces.
