It is clear that Water will be one of the most important topics in the 21rst century. 2 billion people in the world do not have access to potable water and proper waste removal according to the UN. Water resources are being used up faster than they are being replaced. Fresh water resourcing issues are going to be more common. An example is Lake Mead and the Hoover Dam in Nevada. The Colorado river and other water systems are literally drying up, reducing Lake Mead's depth close to where water rationing for many US states will be imposed. This example though extreme, is probably not completely unique. Many areas in the world are suffering from a water scarcity issue, or from a lack of potable water and proper waste removal [using water based systems] .
Technology will resolve these issues. There is no doubt that we have the creativity to solve the many issues around water management. Software, hardware, bio-natural agents, micro-biological cleaning, house water and waste recycling, new filtering, ground water management, treatment methods – all of these and a lot more will be created, recreated or improved in the coming years.
As 'Water' becomes the next great focus of investment and concern, water management in all of its various forms will become one the world's largest growth industries; and a focus for environmentalists and those who are concerned about proper resource management. Water will become a market in which the happy marriage between the environmentalists [at least not the extremists of that group] and capital owners will occur.
I am actively promoting software and digital technology to accumulate information, record it, store it, and generate active and eco-friendly solutions for government agencies, both locally and internationally, with cloud based solutions. Without the information being centralized and accessible, we cannot resolve the many problems which our water systems face. This technology is a platform which will integrate informational sources and allow regulators and actors to assess what can and should be done based on the problem set in question.
A great magazine on the topic of water and water management is water.com
A corollary to this 'emerging' market is the generation of jobs, wealth, and higher living standards. And there is nothing wrong with that.
