Peak Resources investigates the growing concern of global water stress. It is no big secret that the world population of humans is growing at an exponential rate. The growth of the human population has caused almost every nation around the globe to focus its attention on the available of freshwater for the future while some nations must focus on having fresh water today. Add into the mix the continual pressure from global climate change, and you have a lot of trouble. Hotter temperatures mean less ground water, shallower lakes, and rivers, and less water for crops, drinking, and bathing. To set this into motion, MIT researchers developed a new tool that models the ability of the hydrologic cycle to meet the growing needs of the world population through the year 2050.
Water resources are tied to populations of people. By 2050, the world population, is expected to rise to 9.7 Billion. Of those 9.7 billion people, 5 billion are expected to be living in water-stressed communities or regions. Of those 5 billion people, 1 billion are expected to live where there is not enough water to meet daily needs of people, environment, and agriculture. For some nations, this is not news, India, and Middle Eastern countries are already facing water stress issues.
What the MIT model does is it allows researchers to look at the two variables that are going to have the most impact on freshwater over time. Those being socioeconomics, and global climate change. What they find when they look into how the socioeconomic data changes over time, they discovered that the rate at which populations grow and the changes to economic growth lead to situations of water-stress. What they are talking about are emerging markets, where water is already limited. The impact of the situation is made worse by adding in global climate change.
Results of the MIT Model
As populations of villages and cities grow more food is needed, more drinking water is needed, and more water is needed for industry, but water is finite and the amount of available water is decreased as temperatures rise. But emerging markets and developing countries are not the only people hit by water issues and global warming. The study shows that developed nations are also going to feel increased water-stress as time passes and global warming increases. Overall, global warming is expected to impact how, when, and where rain falls. Changing patterns of precipitation will impact most countries around the globe.
While this model shows a good picture of what the future will look like, it shows something even more valuable. It shows that studies and modeling of this nature are deeply important to humanity. Peak Resources sees clearly that those who have the knowledge to forecast accurately, will be the ones who have the power to make changes. Those changes represent resource investment opportunities. Knowledge is the tool that will shape the future. Water demand is getting worse, and as time goes by the question is how do we deal with it today.
