030 But these also have to be upgraded and modernised as demands on the quality of infrastructure and related services rise. In a rapidly globalising economy, it will prove essential for OECD countries and regions to strengthen their competitiveness by using modern, efficient infrastructure to attract technology, mobile capital, skills and knowledge. With mounting costs - inter alia from environmental regulations, rising urban land prices and the increasing complexity of projects, as well as from growing pressures on public finances - there will need to be changes in the ways that many infrastructures are organised and financed. At the same time, a rising share of world infrastructure investment will be conducted in the developing world, notably in the Big 5 economies. However - except perhaps in the case of telecoms, and in countries with traditionally high rates of saving - it is not clear whether developing countries in general will be in a position to mobilise effectively the enormous resources that will be needed to carry out the necessary investments, unless far-reaching reforms are undertaken to improve the governance of infrastructure development and management, as well as the efficiency of these countries' financial markets. If they fail to do so, such countries could experience major disruptions of service with significant adverse effects on their economies, leading to economic slowdown or even stagnation. 4. Interdependencies and synergies among infrastructures As becomes increasingly clear from the analysis conducted above, developments in one infrastructure sector can have important implications for developments in another. These may be complementary effects, as in the case with the application of satellite and other remote sensing technologies to increasingly sophisticated road pricing or metering of electricity and water consumption. Another example is the role that transport infrastructures have historically played in providing right of way for communication networks. The effect may on the other h
