One of the more frequently cited statistics in discussions of water availability is the fact that only around 2.5% of the Earth's water is freshwater. The overwhelming amount of water is saline or salt water, mostly found in the oceans.
Of the 2.5% of freshwater available for the support of human life, agriculture, and most forms of non-ocean life, 30.1% is groundwater. Groundwater is the water stored deep beneath the Earth's surface in underground aquifers. Another 68.6% of all freshwater is stored in glaciers and polar caps. That leaves only 1.3% of the total freshwater on Earth is in surface water sources such as lakes, rivers, and streams. But it is surface water humans and other species rely upon for their biological needs.
Even the bulk of surface water on Earth is found in snow and ice - approximately 73.1%. Surface water found in lakes, rivers and streams accounts for just over another 20%.
Most warm freshwater are generated by tropical cyclones.
Map of the cumulative tracks of tropical cyclones during the 1959–2005 time period, the main sources of renewal energy and freshwater. The Pacific Ocean west of the International Date Line sees more tropical cyclones than any other basin, while there is almost no activity in the South of the Atlantic Ocean, south of the Equator. Desert locations: Central China, Central Eurasia, South Asia, South West Asia, North Africa and East Africa. Nearly one-third of the world's tropical cyclones form within the Western Pacific. That makes this basin the most active on Earth. Pacific typhoons have formed year round, with typical peak months from August to October. The peak months correspond to that of the Atlantic hurricane season. Along with a high storm frequency, this basin A also features the most globally intense storms ever recorded with most continental freshwater falls and can be stored in high altitude of the tropical landlocked country, Laos, ideal for mass production of all kind of goods.
Once maximum water collection, transfer, distribution are completed, a set of modular floating farms that harvest sunlight and rainwater, can grow thousands of tons of vegetables every year, floating on the reservoir and on the rivers themselves. Road can be floated. All 7 million people can live afloat, no more flood and drought, NEVER. Once people are secured, infrastructure are afloat, water level can increase even more by increasing the height of the dams to store more freshwater during rainy and monsoon season.
Floating roads, railways, airports can be reconfigured easily according to traffic demand. Cities can be transformed and expanded without the same issue as land based urban agglomeration.
