Effects of Urbanization on Environment

In addition, vegetated buffers adjacent to the croplands can substantially mitigate agricultural runoff of nutrients and other contaminants via deposition, absorption, and denitrification [20]. Urban areas are primarily located along river networks in the Cao-E River basin. Therefore, urban effects on the river water quality were expected. Urban land use comprised a much smaller percentage of the Cao-E River basin than the cropland in this study. This observation is most likely due to two factors: 1 the deficient capacity of urban sewage treatment plants leads to domestic pollution and industrial wastewater inputs into the Cao-E River system, and 2 the high percentage of impervious surfaces and over fertilization of grassy areas can increase discharge rates, sedimentation and pollutant runoff to streams [44].

Topographical factors played important roles in explaining spatial variations in river water quality within the Cao-E River basin SLP mean was Topography largely regulated the river water quality parameters. However, our results indicated an inverse relationship. The slope effects on water chemistry varied. Watershed physical characteristics, such as soil properties soil texture and soil drainage , morphological variables drainage density and elongation and particularly surficial debris, largely affected water chemistry in river waters [37] , [46].

Similar results were published regarding water quality spatial variations in the Han River basin in South Korea [7] and non-point source effects on stream nutrient concentrations in the Seattle region of the USA [47]. The socio-economic factors commonly have different extent effects on river water quality, especially in developing countries such as China. Our study shows that socioeconomic factors have significant effects on river water quality during the study period Table 5 and that HP d , AHO pc , and GDP pc explain This result can be attributed to high population density, the massive animal production and the lack of strict management regulations for animal waste in the study area.

Most human and animal waste with incomplete treatment is discharged into the surrounding water bodies. Moreover, EC was positively correlated with GDPpc, which was most likely related to point source pollution [37]. In addition, some researches [4] — [6] point out that climate condition is also an important factor of influencing river water quality. Thus, we will further study it in our future work.

This study improved our understanding of the anthropogenic activities and natural factors that affect river water quality and can assist in the design of efficient strategies for controlling river water pollution at the watershed scale. Moderate-resolution remote sensing data were adopted in this study; future investigations will require high-resolution DEM maps and additional land use classes to better evaluate the effects of specific environmental variables on overall river water quality.

Abstract Understanding the primary effects of anthropogenic activities and natural factors on river water quality is important in the study and efficient management of water resources. Introduction The deterioration of river water quality has become a primary environmental concern due to unsustainable anthropogenic activities; the demand for freshwater has been rapidly increasing in many developing countries, especially in China [1] — [3].

Materials and Methods 1 Ethics statement No specific permits were required for the described field studies; the sampling did not cause any disturbance to the environment or to the protected species at the sampling sites.

Discussion 1 Seasonal effects Seasonal variations in the flow caused by the subtropical monsoon climate can partially explain the river water quality temporal variations [7] , [38].

Table 8. Conclusions The primary results of this study can be summarized as follows: The in-stream water quality in the Cao-E River basin streams suggested that TN, pH and T were generally higher in the rainy season, whereas BOD 5 , DO and turbidity were higher in the dry season. Spatial variations in river water quality are typically associated with several anthropogenic and natural factors. Moreover, Animal husbandry output per capita was an important predictor for TP and turbidity, and Gross domestic product per capita largely determined the spatial variations in EC. The remaining unexplained variance resulted from other factors, such as topography.

Moreover, agricultural runoff, industrial pollution and domestic pollution in urban and industrial areas were also important factors within the Cao-E River basin. Supporting Information. Table S1.

The analysis enabled to classify the water quality stations into three groups: good water quality, medium water quality and bad water quality. WQI min resulted in overestimation of the water quality but with similar trend as with WQI and is useful for the periodic routine monitoring program. These jobs pay well and have several added benefits. More of such jobs are continuously being generated in cities and urging a move from rural to an urban lifestyle. Urban areas have several modern technologies and facilities to offer. Cities have become highly tech-savvy with sophisticated communication, medical facilities, infrastructure, enlightenment, dressing code, social amenities, and liberalization.

People entertain the idea that they shall have much better lives in urban places. Most localities are taking up an urban form of life. Minerals are discovered, and natural resources are exploited for commercial reasons. This turns rural areas into growing cities. An increase in productivity causes economic growth and creates employment opportunities. Wherever these two exist, there is a natural inflow of people.

Better education facilities, opportunities to study in reputed universities and colleges and better quality of education attract young people towards urban settlements. Their mindset suggests that acquiring a better quality of education will increase their employability. It will ensure a safe and secure future. Hence, the need for education is one of the various reasons for increased urbanization.

Every coin has two sides. Let us take a look at some of these effects-. Urbanizations lead to the creation of employment, better job opportunities, availability of technological facilities, improvement in infrastructural facilities, etc. The quality of education also improves, and people are provided with better medical facilities and healthcare requirements. There are better communication and transportation facilities in urban areas. Naturally, the living standards of the population improve. They become financially stable enough to avail all these facilities with better quality.

City life generates the market potential of the population. Their shopping potential increases manifold. It leads to the development of malls and shopping complexes. These malls cater to various needs , including entertainment, food, recreation, cultural activities, and many more. But most of these shopping complexes are owned by national and international companies. These significantly interfere in the growth of small independent businesses. Due to advancements in the field of technology in urban areas, they can provide a variety of services to the people. These services are not available in rural areas. Proper medical care, education, transportation, etc. Even recreational facilities are more advanced in urban settlements. An increase in the number of people within any area results in the problem of accommodation.

The population has also significantly increased in the last few years. Because of this population pressure, urban areas face a scarcity of housing facilities. It occurs because the expansion of housing and public utilities has been insufficient. Building material is also expensive, which cannot be afforded by everybody. Since there is a lack of housing facilities, many people are forced to share small living spaces. Congestion has significantly increased with the influx of rural population into urban areas. It increases pressure on land and resources, creating a scarcity of basic amenities.

Although the primary reason for urbanization was ample job opportunities, the situation has dramatically reversed now. Since several people flock to cities in search of jobs, employing every one of them becomes difficult. Moreover, jobs have become highly specialized- not everyone can meet all the job requirements of a profile. Where the population has increased, resources have remained minimal. One major crisis that big cities face today is water scarcity.
