image00111 By Sushant Shrestha Urbanization in all over the world is proceeding exceptionally fast. Peripheral zones are being pushed by urbanization causing conversion of rural to urban at large. This rapid urban growth has created a chaotic mixture of urban and rural land use. Urbanization has been underpinned by the rapid growth in the world economy. Human beings have become an increasingly powerful environmental force over the last 10k years. With the advent of agriculture 8k years ago, we began to change the land. And with the industrial revolution, we began to affect our atmosphere. The recent increase in the world's population has magnified the effects of our agricultural and economic activities. But the growth in world population has masked what may be even more important human-environmental interaction: While the world's population is doubling, the world's urban population is tripling. The promise of jobs and prosperity, among other factors, pulls people to cities. Half of the global population already lives in cities, and by 2050 two-thirds of the world population is expected to live in urban areas. Nepal is also badly affected by urbanization. Yes, urbanization is the good sign of development but the turning of fertile alluvial soil into cities is harmful to the environment and has adverse affect on human health. People are buying farming land and are converting into plotting. In my locality, one can hardly see the farming land but a numerous numbers of plotting. And without the real estate form they buy and sell those lands. These activities are none other than illegal activities. So these activities must be stopped before it’s too late. Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption are exacerbated by the increasing population density and demands of urban environments. Strong city planning is essential in managing these stuffs.
