I have begun the growing in significance topic of water scarcity. Combine that concept with severe top soil erosion around the world and what do you get? Food scarcity.
I didn't write in this blog to scare, intimidate, and have no intention to neglect other very important issues. For me, the most fundamental thing to all our lives is water, wood, and shelter.
Water: We are tapping our groundwater and snow pack reserves at alarming rates around the world. As the world population continues to grow it will use more water. As countries continue to develop in developing regions such as Africa, and Asia the pressure on their water resources will continue to increase. This is not just a African or Asian problem where huge populations are growing at alarming rates, but also an American problem. Given I am writing this from the New York City area and we have basically spent the last 30 days under water, the largest problem lies in the west. From extensive irrigation in California, arid land city population rise such as in Phoenix, and continued and extensive water waste in infrastructure and agricultural use; we driving ourselves off a cliff. I just read an interesting article in the December 2008 issue of National Geographic which highlighted the issue of damming up the rivers in Northern California and southern Oregon and its effect on Chinook Salmon populations. We recently had a "30,000" salmon die off from 1 river valley (Klamath River) alone. Environmentalist are trying to remove the dams and farmer's are asking for more water. Both have very valid points, but I wish to point out the one big flaw in the farmer's point. Most farm in the US and world are huge centers of waste regarding water. Farming techniques have developed over the past few years and most significantly Israel, the land of little water developed the drip irrigation system. The most efficient way to water a crop, providing enough water to the roots to optimal growth. Our great American farms mostly use significantly more water than they need, so why fight for the overuse of water when the market (price) should force you to become more efficient.
Topsoil: What is better than digging in a garden, planting a variety of crops watching and waiting while you watch the mature? Better? Well how about being gone for a week to find that all your beans have been eaten by an animal. Very annoying. But seriously, Top soil erosion & fertile soil aeration is becoming an increasing problem in areas with very larger population such as China and India. China I believe is seeing the largest problems regarding this. The Gobi Desert is growing, fast. Hillside farming through unsustainable practices and eroding, fast.
What this means for food: Less water + less soil + larger appetite = ??? You don't have to be a scientist to figure this one out. My greatest concern is what happens when China cannot feed it's population anymore? There will be political unrest, death, and I hate to say it but political conflict. I don't mean to single out the Chinese, but there is a list of countries that face severe problems. Haiti has some of poorest individual in the world, that lack basic freedom of water and food. Why? For a period of 5 or 10 years the population grew with the market or government offering a sustainable method of energy and heat. Haitians went into their forests and cut down almost every tree in the country. Since then soil erosion has been a huge issue, without any trees and a hurricane coming how will the soil stay in place? Soil erosion turned into water scarcity because the trees and soil held in the water to be release slowly in rivers. Which meant severe flooding and famine.
No more doom and gloom from me. The tools are at our disposal to correct the inefficiencies in the world. What is lacking is education. I hope this post made 1 person interested in learning more (not from a grammatical point of view though :) )
