The rainwater that washes away the chemicals, sediments, motor oil, antifreeze pollutants, and fertilizers ends up in the nearest beaches and causes a huge environmental risk. At the combined sewer plants, untreated domestic and industrial waste water overflows during a rainy season and ends up into the streams and beaches. Similarly, sanitary systems are affected by blockades, line breaks, sewer defects and leaks, inadequate design and vandalism, and lapses in maintenance to force the polluted water to make its way to the streams and beaches. The combined grease, chemicals, nutrients, mixture of raw sewage, industrial wastewater, harmful metals, and bacteria have resulted in the closing of several beaches, shellfish bed closing, and aesthetic and environmental problems (“Sources of Beach Pollution”). Moreover, the discharges from recreational and commercial vessels such as trash, fishing gear, ballast water, domestic waste, paints, and other chemicals are also a source of pollution for the beaches as an increased number of such vessels contributes towards the accumulation of waste and pollution from them.
The process of urbanization is linked with the economic development, which makes an increasingly higher contribution of the national economy. However, when the growth of urban population takes place at an exceptionally rapid rate, most cities and towns are unable to cope with changing situations due to their internal resources constraints and management limitations. Provision of infrastructure services viz., water drainage and sanitation along with waste disposal are greatest concern to human settlements. Failure to provide these services adequately results in many of well-known costs of rapid urbanization: threats to health, loss of urban productivity and environmental quality. On one hand, pressures for modernization give rise to continuous development activities, which deplete natural resources.
That is why flooding situation occurs in low-lying areas of Surat city. Some major creeks also not much sufficient to drain the access stormwater because of the path of this creeks is obstructed by some manmade obstruction and it is becoming narrow due to silting. Some location flood is occurs by overflowing of this major creeks of central zone of Surat
Generally, urban development will change, alter, affect or make a significant impact on the environment. The construction of buildings and roads has extensively changed the hydraulic properties of many habitable human settlements. Naturally, some areas have been observed to be less permeable or even impermeable to storm water and these areas are depressed and raised to check ponding or dishing to trap runoff in the environment. The construction of surface and conduit drainages is constructed to drain runoff efficiently and sustainably in well planned urban areas always remove natural vegetation which causes reduction, interception and transpiration of plants in the environment (CSIR, 2000). These limited vegetation cover in the environment
DIGITAL ASSIGNMENT-01 17BCE2049 LINGALA ANTHONY NIKHIL REDDY Urban environmental problems and solutions in India. Introduction: Recent concern for the environment is not only due to natural phenomenon, but the urbanization has made people more aware of the environmental issues and their quality. population beyond the multiple times of the sustaining capacity has made the urban centres polluted, overcrowded and exerted pressures on social and physical amenities.The Concentration of industries in and around urban centres has exposed the urban population to all sorts of risks. These risks can remain unnoticed due to its slow introduction such as increasing the quantity of pollutants in river Ganga, or can be sudden due to some
The major sources of water pollution in the Philippines are inadequately treated domestic wastewater or sewage, agricultural wastewater, industrial wastewater, and nonpoint sources such as rain- and groundwater runoff from solid waste or garbage deposits, which is also known as leachate. (The Problem) Water pollution in the Philippines can cause waterborne diseases by drinking polluted water: Typhoid, Amoebiasis, Giardiasis, Ascariasis, and Hookworm. Water pollution may also result from interactions between water and contaminated soil, as well as from deposition of air contaminants (such as acid rain) (Pollution Effects On Humans, Animals, Plants and The Environment) The World Bank estimates that exposure to water pollution and poor sanitation account for one-sixth of reported disease cases, and nearly 6,000 premature deaths per year. The cost of treatment and lost income from illness and death due to water pollution is pegged at PHP 6.7 billion (US$134 million) per year (PEM 2006). (Lohani, B. N., and T. M. Roblo) (Lohani, B. N., and T. M. Roblo) The area in the Philippines that are affected by water pollution are: According to data from the Philippine Environment Monitor and the EMB, four regions had unsatisfactory ratings for their water quality criteria.
Like the others developing countries, solid waste management is a serious confront to Ethiopia. This is mainly due to rapid urbanization and population growth. Many towns in the country lack the financial resources and institutional capacity to provide the needed municipal infrastructure for adequate solid waste management (Dagnew et al, 2012). The solid waste management in Ethiopian cities has not been carried out in a sufficient, suitable and appropriate manner. As a result, the quality of environment in cities has become more serious from time to time, and people are suffering from living in such
It means that, environmental problem is an event that cause burden to the environment which its occurrence was the result of urban activities. With this regard, flash flood was considered as an environmental problem because it can harms urban environment Basic environmental impacts of flash flood are changes of structure along the river course and erosion and deposition of mud at river banks and roads. Besides that, it also caused low level household wastes to be dispersed into rivers and resulted in contamination of water supplies for the community living in urban area. During flood, toxic and rubbish will enter into rivers and therefore may harm the aquatic life as well as the cleanliness of the river. Therefore, this event might lead to other urban problem which are shortage of clean and safe water supply.
In Asian economies, road congestion has already costs an estimated 2%–5% of gross domestic product (GDP) every year due to lost time and higher transport costs. The region 's cities suffer from the highest air pollution levels in the world, with as much as 80% attributable to transport.
He called Metro Manila the ‘Gates of Hell’(Flatplanet,2014). This indicates that the traffic congestion in Manila is really beyond normal that is even acknowledged internationally. Therefore, the Philippine government should fix the current competition in Metro Manila by decongesting by way of proper zoning of businesses and firms, for this is a feasible solution for the congestion in the
