Mega Water Project China Is Useless
Enormous water transportation from the South of China to the dryer Northern regions seems to be useless. This is one of the conclusions mentioned in a scientific report which is published in PNAS. China has been building a canal from the South to Peking. A distance of 750 miles (1200 km). Transportation of water will supply only 5% in the water needs of Beijing while the Southern exporting provincies will be running out of water.
Future water stress
Future water stress in the main water-exporting provinces is likely to increase further, based on analysis of the historical trajectory of the major governing socioeconomic and technical factors and the full implementation of policy initiatives relating to water use and economic development.
Improving water use efficiency is key to mitigating water stress. The efficiency gains will be largely offset by the water demand increase caused by continued economic development. China will have to pay a much greater attention to water demand management rather than the current focus on supply-oriented management.
Water shortage is not only a result of the modern live style of citizens in the capital. Because of the growing population and migration to big cities like Beijing and Tsinghua – and climate change effects – the agri-industry also needs more water for irrigation. And industries spent a lot of water during their processes as well. The government is advised to stimulate sustainable new water technologies for industries, farmers and citizens to challenge the future. The “Nan Shui Bei Diao” – literally South North Water Move – is the largest water transfer project in the world. China. In the footsteps of this colossal project, the film stands Antoine Boutet mapping an engineering territory cement beats plains, rivers leave their beds, deserts become forests, which gradually voices s ‘rise, demanding justice and the right to speak.
Freshwater availability is relevant to almost all socioeconomic and environmental impacts of climate and demographic change and their implications for sustainability. An global group of scientists compared ensembles of water supply and demand projections driven by ensemble output from five global climate models. There are reasons for concern. Direct climate impacts to maize, soybean, wheat, and rice involve losses of 400–2,600 Pcal (8–43% of present-day total). Freshwater limitations in some heavily irrigated regions could necessitate reversion of 20–60 Mha of cropland from irrigated to rainfed management, and a further loss of 600–2,900 Pcal. Freshwater abundance in other regions could help ameliorate these losses, but substantial investment in infrastructure will be required.
