Migration to Cities Drains Resouses

Migration from rural areas to the mega-cities in search of food, job and security is a natural process. But every city has its limitation; it has its own saturation point and if exceeded, a city might falter while providing basic facilities to its residents. As modern mega-cities are now choking with the pressure of ever growing population, scientists fear that in near future these cities might have to face an acute food and water crisis.

Though the effects of excessive population will be felt worldwide, recent studies suggests that cities are going to get worst affected by this ensuing upheaval. If world population goes unchecked and if the exodus to cities continues, we will have to face a series of unfortunate events such as the rise in the food price, the rise of demand for water, energy and other basic amenities or the total breakdown of the entire system.

Recent studies show that in 2030 world population can rise up to 8 billion – 33 % more than the current population of the world. This means that we need to produce more energy, more food and more drinkable water to cater the growing demand. But the fact is that, most of the modern cities neither have the resource nor have the technology to deal with the problem of such magnitude. On top of this, the threat of global warming, irregular behavior of the weather and rising sea level will aggravate the situation further. The demand of energy will rise drastically in the developing world, more particularly in India and China. As people in these developing countries will have more money in coming years, their lifestyle will change and this mean they will consume more energy and resource than ever. If this trend continues, it can destabilize the socio-economic condition of these cities, as these countries are not well prepared.

With the encroachment of cities in surrounding areas, water resources will go dry. Furthermore, production of food will go down dramatically as more and more arable land will be used for residential or commercial purposes. Now the question is how the cities are going to face these challenges. We need to figure it out first and thankfully; a number of scientists are now engaged in this task. To be clear, we cannot stop the growth of population or the migration to cities forcefully. Now, what we can do is to use the power of technology to solve some basis issues like food and water crisis. We can also create employment opportunities in rural areas so that we can get sometimes to be prepared.
