Effect On Air Pollution Of Kathmandu Valley

Effect On Air Pollution Of capital of Nepal v completelyeyClean lineage is necessary for human health. Human body take ons approximately 25 kg of distribute per day to keep up its requirement of oxygen (CEN, 2002). It replicates signifies the importance of duck soup to human beings and both contamination in the line of reasoning bequeath acquit a direct strike on our health. splendid transmission line consists 21% of oxygen 78% of nitrogen and 1% an a nonher(prenominal)(prenominal) gases. If the assembly line composition is change by the increase in ducking of certain gases or by intrusion of non-gaseous components like particulate matters, then the beam is understood to be polluted and the components that alter the in here(predicate)nt compositional property of give vent be termed as oxygenise pollutants. Air contamination affects almost all aspects of the environs including the biota and the sensible components where they strive on. A variety of sources b edevil been identified as the components of the shine contamination and they include both the natural and anthropogenic sources of origin however, the anthropogenic sources of melodic phrase out taint be more pronounced. Anthropogenic strip pollutants be more harmful and include Particulate matter (PM), Sulphur Dioxide (SO2), nitrogen Oxides (NOx), Carbon monoxide (CO), buy the farm (Pb), O zone (O3) and Hydrocarbons (HCs). (CEN, 2002)Air pollution is a big issue all over the world chief(prenominal)ly in urban personnel fields beca usage of fossil fuel driven expatriation system.. Besides this, the unmanaged booming of urban settlements has helped to increase the concentration of breeze pollutants by limiting their horizontal dispersion in that locationby interfering with the health of masses. principal(prenominal)ly, children, elderly and the patients of lungs and bomberstance are more unsafe to the nitty-grittys of air pollution. According to Asian Develop ment Bank (2001), in the South Asian Cities, approximately 100,000 premature deaths e real(prenominal) year is ca utilize by the detrimental accomplishments of air pollution.Air Pollution in capital of NepalThe issue of air pollution in capital of Nepal vale is continuously drawing the attention of concerned bodies and the gravity of the problem is growing year by year. owe to the topography of Kathmandu Valley, growing population, haphazard urbanization and increase in vehicle density imparted as an effect of affluence and need to serve the growing population, the valley has been facing worse situation of ambient air every year. However, the issue of air pollution in Kathmandu Valley doesnt bear a great history as the development of avenue networks and history of conveyance system in the valley do non have the yearn history either. Many researches and the discourse held indoors the country on air pollution has identified the transportation system and linked with it, the poo r situation of the infrastructure as the fore causes of air pollution in Kathmandu Valley. Regarding the dominant air pollutant of Kathmandu, it is Particulate Matter (PM), the concentration of which is ascertained higher during night in the winter due(p) to the creation of inversion layer which acts as the back to trap pollutants. The PM concentration in Kathmandu has always exceeded the World Health Organization (WHO) specimen and guinea pig Ambient Air Quality Standard of Nepal. Besides particulate matters (PM10 and PM2.5) the concentration of other pollutants are non a major issue in Kathmandu Valley. Gaseous pollutants such as NO2 and SO2 are by and large within prototypes but the concentration of NO2 is fairly high in areas with heavy relations and this has the likely of future increase with further increase in reduce of vehicles operating within the valley. Another voltage concern is the concentration of air toxins such as benzene and poly aromatic hydrocarbons (P AH). The concentration of benzene is within subject area standards but the national standard of 20g/m3 is itself fairly high. Although Nepal does not have any standards for PAH, monitoring done in 2003 indicated fairly high levels of these pollutants in Kathmandu Valley. (ICIMOD, 2007)PM2.5 is considered to be more equivocal than PM10. Although Nepal does not have any standards for PM2.5, virtually monitoring has been carried out for PM2.5 in Kathmandu Valley. (ICIMOD, 2007)Statement of jobKathmandu, the capital city of Nepal is the focus of all the major facets of the country, namely economy, tourism, culture, politics, administration and natural environment.Due to the preceding(prenominal) reasons, the population of Kathmandu valley is increasing day by day. Apart from this, the infrastructure development has neer been able to keep up with the unmanaged and accelerating growth. As a result, this has led to increase in slums, inadequate and polluted drinking water supply, pol luted air to breathe, haphazard manner of dumping the solid waste in the neighborhoods.Every mountain have right to breath clean air. Increase in population, vehicular fleet, vital force consumption and industries, brinyly brick industries have contributed to degrade air quality in Kathmandu valley. Overall, the bowl or the cup shaped topography of the valley as well has prevented the dispersion of air pollutants to longer distances.Research questionsThe research will address following issues1. What is the main air pollution facing by local battalion in Kathmandu valley?2. What are the main originational changes that have been made to tick the air pollution?3. What are strength and weakness of these organisational changes?4. What further policy measures should be instituted to reduce air pollution to acceptable levels?2. BackgroundKathmandu is the capital city of Nepal. The Kathmandu valley consists of iii major cities i.e Kathmandu, Lalitpur and Bhaktapur. Kathmandu Valley is situated in 27 3730 N and 27 450 N latitude and 85 150 E and 85 2230 E longitude. And the Kathmandu valley is located at an altitude of 1350meters. The Kathmandu valley is oval shaped and surrounded by high hill range. And the area of Kathmandu valley is 340 and the total population of Kathmandu valley is 1,442,271(CBS 2001). The climate of Kathmandu valley is sub tropical temperate. Along with it have four seasons pre-monsoon, monsoon, post monsoon and winter. In general, average temperature in summer is 32c and in winter is 5c. Due to scotch activity and high chances of opportunities and facilities many people from all around the country has been migrated in the Kathmandu valley and is been highly dense. Air pollution in the Kathmandu Valley has been one of the major problems. It brush off be said that air pollution started as the invention of thoroughfare networks and automobiles. richly population with unplanned and unmanaged urbanization, rapid increasing of automob iles, vehicles and industries are the figures in the causes of air pollution.http// http//, date30th November 2010)According to the presentation given by traffic police, road length per traffic police has meliorate since 1995 from 2.3 km to 1.6 km that is good sign for better traffic management. Nevertheless, due to immense rise in the number of vehicles in Kathmandu, the traffic police are laden with responsibilities of higher number of vehicles than they had to be for 1995. From 2002 to 2009, the total number of vehicles in Bagmati zone increased by 1.25 durations than that was before 2002 from 176415 to 396151. The statistics channelize that the vehicles has progressively increased from 2002 to 2009, the only exception being at 2006/07 probably due to the cause of modern-day political situation. The number of vehicles for individual traffic police has increased from 165 in 1995 to 415 in 2008 i.e. mo re than 2.5 times. In reality, the number of vehicles a traffic police should look for is even higher because not all the traffic police within Kathmandu are in duty at the alike(p) time during a day.In the mise en scene of road length and vehicle numbers, the nominal increase in road length has resulted in crowding of roads. The population density per kilometer road length during 1995 was 1668 that rose to 2353 in 2008 while, the number of vehicles per kilometer road length in Kathmandu was 70 in 1995 that has risen by about four times i.e. 255 in 2008. Moreover, in shield of Kathmandu the traffic congestion, in practice, is observed due to the inadequate road width and lack of proper identification of the road lane for vehicles pitiful from the black eye directions. The proper traffic management can thus be initiated with the argument of lane, which can, as excess benefit, reduce the vehicle collision and traffic accident.Figure Comparison on Transportation Attributes for 1 995 and 2005(Source Valley occupation Control, 2009 where Blue colour de do itrs 1995 and red is 2005)Causes of Air pollutionIf any unwanted particles mixed in the air, it is called air pollution. It can cause for both humanWell as environment also. Air pollutants can be in the form of solid particles, liquid as well asgas form. They are may be either natural or artificial. Main artificial air pollutants are SulfurOxides, Nitrogen Oxides, Carbon monoxide, Carbon dioxide, Volatile organic compounds,Particulate matters, ground ozone, ammonia etc. (Wikipedia).Sources of artificial air pollution are as followsi) Rapid Urbanizationii) vehicular dischargeiii) Industrial growthiv) Unmanaged governing of waste etc.3. THEORY3.1 Concept of inventionAn psychiatric hospital is any structure or utensil of social order or it may bee said as a set of some perfunctory rules, regulation and norms of some formal rules, regulation and norms formulate to establish the smooth running society or to govern the behavior of human being in the society. Institutions are formed to formalize the society and to show the human being to act as a social animal. It is the sequel of the society and can be said as the need in the human community to harmonize the behavior of the people. The term institution is popularly applied to customs and behavior patterns important to a society, as well as to item formal organizations of presidency and usual service (Stanford Encyclopedia social institutions).Although individual, formal organizations, commonly identifies as Institution may be deliberately and intentionally created by people, the development and functioning of institutions in society in general may be regarded as an instance of emergency, that is institution arise, develop and function in a pattern of social self organizations, which goes beyond the conscious intentions of the individual human involved (http//en, 28th nov. 2010). The institution that has been established to enhance the quality of ambient air quality in Kathmandu is the outcome of the result from the air pollution. Those are not demand of the people but the result of the problem. The criminalize of two stroke vehicles in Kathmandu, banning of brick kiln factories was not in favor of people. It just chalk up on the head of the poor people in the society, but that was the outcomes of the problems not as the intentional outcomes.3.2 Resource example and Resource RegimesThose goods which consists of a natural or human made resource system whose size or characteristics makes it constitutely but not impossible to exclude the people from getting benefits from its use are generally known as common-pool resource (CPR) or it may be called as common-property resources. Since the common-pool resources are open access, thither is the problem off congestion or over use. Unlike humanity goods, they are subtractable. A common pool resource for example air is a large burgeon forth but only provides the restrain quantity of extractable unit and over use will create problems as we are here to discuss the air pollution in Kathmandu. A common property regime is a peculiar(prenominal) social arrangement regulating the preservation, maintenance, and consumption of a common pool resource. The use of the term super acid property resource to designate a type of good has been critized, because common pool resource is not necessarily governed by common property regimes.(http//,date26th Nov.2010).Example may be interpreted as the air in Kathmandu which is the common pool resources. It allows certain amount of pollutants but beyond this the gets polluted. in that respect will be various consequences as it gets polluted. Because the core resource is vulnerable, it is subjected to congestion, over use and in conclusion pollution. Any system has their own certain capacity to cope with the c hange and beyond that the system gets disorder and in case off air in Kathmandu, situation came due to the dramatic increase in population and overweening use of vehicles that run by the fossil-fuels. The use of common pool resources can be continuously done as the loop if they are managed properly and carefully exploited because they form the dogmatic feedback loop since they are stock variable but the haphazard use of it deteriorates the stock and disrupt the break away variable for good.3.2.1 Resource Use in KathmanduOpen accessMarketEffect of statistical distributionNo rulesAs shown in the above figure, the air in the Kathmandu was open access and on that point was no any rules concerning the use of it and the ownership for it. As the time passes, there araised several agents and market introduced. The outcome of the dramatic increase in the population in the city results in the excessive use of vehicles for the transportation system. Unfortunately those vehicles are run by fossil fuel which when used disclose air pollutant in the atmosphere. So there is the pollution problem in the valley. Now giving medication has their head towards it and they are formulating institution to enhance thee quality of it.Though the air in the valley is open access but there are some rules concerning the use of it. Thee government have introduced kilobyte taxation, banning of diesel running three wheelers etc. Now the system turn upes where it is still the open access but with market, shown in the figure above. There are some rules concerning the use of it and hence thee distributional have came into action in this case.3.3 Framework for Analyzing for resource use problemAir in the Kathmandu valley is common property and is open access. At the time passes, the engineering has developed as well as the population of city increase dramatically. This is partially due the centralization and civil war in Nepal. If the natural resources was vast compare to the capacity of people to use it, there could be no problem (vatn, 2005), but here the thing is just opposite to that.TechnologyAttributes of the resources unwrapcomes-resource use-state of resourceAgents and aagents choicesPatterns of interactionInstitutions- regimesConventionNormsFormal rules(Source Vatn, 2005,)(Figure Framework for analyzing resource use problems)lastly this aspect has influence has chose new institution and government of Nepal formulated some rules and regulation for the enhancement of air quality in Kathmandu valley. Along with this, diametric Medias, NGOs, INGOs are involved to cause people regarding air pollution. The institution such as banning of two stock vehicles, relocation of Himal cement factory, introduction of green tax was introduced.Although there are many such many rules regulation and acts came into existence but some the institution lack third party control system. The government formulated the rules and people were not seemed to walking along with this cha nge. Since there was lack of third party no body were there to check and control the implementation of such policies.With regards to institution we may also distinguish between outgrowthal rules, rules concerning the defining of operation rules and finally external arrangement / rules. The operational rule defines the everyday regulation regimes. (Vatn, 2005).The next important factor to take into consideration is agents and agents choice. Here the structure of institution greatly helps to motivate the people. Institution in Nepal was so formed that people were motivated and aware of air pollution and its impact to some extent. But the technology did not fit the resource use. As being the developing county the people do not have any option rather than to use fissile fuels as the main source of energy for the transportation system. At the same time dramatic increase in population in the city force to consume more fuel energy and Kathmandu valley stood starting signal in position in term of vehicle registration in Nepal. So the air being the open access was very vulnerable to risk.Eventually due interaction of technology and choice of agents the problem of air pollution came in the valley. There difficulties are mainly due to four factors. Basically regime is not able to motivate correlation action in accordance with what is demanded given resource characteristic, technology, number of agents and corruption by the government official. Corruption is so deep rooted that one can easily break up the institution formulated by the state. This can be seen as the drawback of the system or the lack of motivation.If outcomes are not in accordance what is expected or wanted agents can change institutional structures. In oral sex this may occur at all level, with regards to conventions, norms and formal rules (Vatn, 2005). However, changing such rules and regulation certainly need considerable time and result of such change to the institution can only be sight after som e period of time.3.4 Air as a common pool resource in KathmanduGoods or resources can be generally classified into two groups. They are Excludable or Non-excludable and contest or Non Rivalry. When a person or a firm can set a parapet on his/her property like land to prevent the use of it by other are called excludable goods and those where the demarcation is not possible are called non-excludable goods. When the goods at one time prevent the use off same good simultaneously by other is called rivalry goods and on the other hand, just like air, the of which can never stop other to use it at the same time is called non-rivalry goods or resource.Exclusion be (TCs)Low HighIIIIIIIVYesRivalry in use orconsumption No(Source Vatn, 2005, pp 263)(Fig Characterization of resources or goods according to the address of exclusion and rivalry in use or consumption).While goods of type I are typically labeled Private goods, type II and type IV are called goods and public goods, respectively. W ith regards to type III, common-pool-resourceis an often used concept. In the tradition of edge of resource characteristics to regime implication, type I is often equated with semiprivate property and markets, II with clubs, III with standard common property or open access and IV with state/public property. (Vatn, 2005, pp 263)3.4.1 Rivalry goodsAs we are discussing about the in the Kathmandu valley, it can bee seen that the resource is rivalry type. In Kathmandu valley, different types of factories, industries, vehicles are continuously meeting the air pollutant which ultimately invited the pollution problem and all the citizens are harm from it. In the case of rival goods, the core problem is that of external effect. This is typically the case for many environmental resources where use-at least beyond the certain level-reduce its quantity and/or quality (Vatn, 2005, pp263). Therefore air in case of Kathmandu valley can be considered as rival goods.3.4.2 Non-Excludable goodsWhen the goods are private or own by certain people or organization, than the demarcation is very easy that means operation cost is very low. But when thee goods or resources are open access or common property, the exclusion cost is very high because the typical demarcation is not possible. In this case, air is common property and everybody in the city can use it undoubtly and the performance cost is very high3.5 Mechanism to reduce air pollutionThe pollution problem in Kathmandu can be seen as the outcome of excessive energy used and technological development. This can simply be framed as followsProduction stimulant drugOut rove3.5.1 Taxation inputBasically the major pollution problem in the valley is due to the excessive use of the vehicles which are runes by the petroleum products. So air pollution can be reduced by introducing the tax in the fossil fuel. This is the best way because there is low transaction cost in doing so. High tax in the fule wills automatically reduce the use of private vehicles and the public vehicles uses will be increased to the considerable extent.3.5.2 Taxation in production and technologyOn the other hand, this can be done by introducing the tax in the technology that means motor car, private vehicles, and factories, industries which use energy and emit the pollutants in the air and also providing the subsidy to those who use bicycle or electronic means of transportation. As the government of Nepal is doing , banning of diesel running three wheelers, two stock vehicles are also the way to enhance the air quality to some extent. This is a very fair way and there is low transaction cost in introduction such institutions but this dominantly hit the poor in the society.3.5.3 Taxation in OutputThere is another way of controlling the air pollution but the transaction cost in very high in doing so. The introduction of rise tax can be very good way to enhance the air quality. Here the transaction cost will be fairly very high.4. MethodsF or fulfilling the content objectives, a systematic study approach was followed. The major base for research launched with the collection of relevant secondary data and information from various national and international sources. The field-based study could not be done.The following process are doneLiterature retreadSecondary Data CollectionData AnalysisDraft story PreparationFinal ReportDissemination5. AnalysisIncreasing number of vehicles without extension of roads is diagnosed to be the major problem in Kathmandu. The growth of the vehicles in Kathmandu is a major concern to traffic police, vehicle drivers, and pedestrians. From the result, it is observed that the road length of Kathmandu is increasing very nominally while the numbers of vehicles are increasing with an exceeding growth rate and it ultimately help to increase air pollution.5.1 Causes of Air PollutionAir pollution causes by both anthropogenic as well as natural sources. Anthropogenic source is the main cause in Kathmandu valley than that of natural source. Mainly fossil fuel com tutortion and other activities like brick factories, unmanaged road system, stone grinding factories are added pollution. vehicle system is the main source to emit carbon monoxide, hydrocarbons, and nitrogen oxide. Approximately 67 percent of Particulate matter is supplied by vehicular emission in Kathmandu valley.5.1.1 Sources of air pollutionSources of air pollution are of two types Natural and artificial.Main sources of artificial air pollution are as followsA) Rapid UrbanizationKathmandu valley has very fertile land, but nowadays it is known as unmanaged urban area. The main cause of this is Kathmandu-centric development and migration of people due to insurgency and political conflict. It is the biggest city of the Nepal and about 20 percent urban people live here. The population increase rate here is as twice as national rate of 2.2%. (ICIMOD, 2007).B) Vehicular EmissionIt is the main source for air pollutio n. According to the Department of Transportation and Management, presidential term of Nepal, the first bus service in Nepal commenced in1957 and since then the fleet has grown substantially. The cumulative vehicular number in Bagmati zone (administrative zone where the vehicles of Kathmandu Valley are registered) was 176,415 in 2001 and it reached 396,151 in 2008. Most of the vehicles registered in Bagmati zone is used in Kathmandu valley. This record shows the rapid increment of vehicles in Kathmandu valley. Vehicle number in Kathmandu has been increasing rapidly in the last five years.C) Industrial EmissionsAbout two-fifth industries in Nepal are located in Kathmandu valley. According to the Department of Cottage and small industries, there were 14,971 up to 2006. Out of them, 111 are brick kilns and 89 are stone crushers. They contribute 14% of the total particulate matter in Kathmandu valley. Management of solid waste is another problem which also causes air pollution and vulne rable to health. (ICIMOD,2007)5.1.2 Effects of air pollutionThe effect of air pollution is high in human health. High exposure in air pollution may cause chronic bronchitis, lung cancer, asthma and other respiratory problems. It also affects cardio vascular system and awkward system (Lahiri, 2003). Particulate matter is the main problem of Kathmandu, which not only affects the health but also the tourism industry. Due to the poor health, human productivity is also loss. All these impacts finally affect the economic system of individual as well as of state.The long term study of health impact due to air pollution is yet to be conducted in Kathmandu Valley. However, Child Workers in Nepal Concerned Centre (CWIN) surveyed about 60 children who were working as staffs on three-wheelers in valley and result showed that 84% staffs were misfortunate from eye problem, 82% chest pains, 66% were suffering from coughs and 58% by headaches. Similarly 45% children were suffering by respiratory problem.Shakya S conducted a study incorporating questionnaires to the traffic police. He observed that out of 90 traffic police, most of them were suffering from diseases related to nervous and respiratory systems. Similarly, Clean Energy Nepal (CEN) also did a questionnaire survey for the people who live near to the brick industries and in control area. The study revealed that 54% out of surveyed people near to the brick kiln were suffering from respiratory problem and 41% people in the control area were affected by respiratory disorder.The other problems due to air pollution are as followsAcid rainOzone layer depletionReduction of visibilityIn context of Kathmandu, the issues of acid rain and ozone layer depletion are not very significant as both of these issues are the outcomes of the heavy industrial pollution. The formation of the photochemical smog and acid droplets due to hydration of the SOx and NOx are not well defined in the pollution status of the ambient air of Kathmand u. As mentioned in the before sections the concentrations of both these gases are well below the standards set by the Government of Nepal and WHO. However, regarding the visibility the problem perpetuates in Kathmandu during all seasons with even more pronounced effects during the winters when temperature inversion takes place. The visibility problem is farm animalamentally caused by the particulate matters and the problem subsides only during the periods of heavy rainfall.5.2. Policies and institutional arrangements for managing emissions from motor vehiclesA number of programs have been done to fight against the air pollution in Kathmandu Valley. Some are given below. In 1991, government stopped to register three-wheelers. It was the first response related to air pollution of Kathmandu valley. In 1994, government place emission standards for in-use vehicles. Green stickers were given those vehicles which met emission values. Ministry of Population and Environment was established in 1995. Environmet Protection Act 2000 and Rules were enacted in 1997. In 1998, the government formulated NVMES in 2000 these standards, equivalent to EURO-I emission norms, went into effect from January 2000. All new means of transportation imported from abroad since then have had to meet the terms. In 1997 the government decided to provide financial support to battery-operated electric three-wheelers. It was given in the form of tax breaks. In 1999, diesel three-wheelers were banned in Kathmandu Valley. Similarly it was banned in other cities also. Vehicle owners were given tax incentive to buy new vehicles. In November 2000, the government decided to ban public vehicles older than 20 years. Similarly it banned all two stroke vehicle in Kathmandu Valley. The policy was followed from 16 November, 2001. Government tried to follow this rule strictly but was unable to put into practice the decision. In late 2000, two-stroke motorcycle registration was restricted. The vehicle run by LPG and CPG (compressed natural gas) was improved from 2000. In 2001, government decided adds 10% extra tax for the vehicle having older than 15 years. This is the first case that government linked between tax and vehicle age. It helped to discourage the use of older vehicles. In 2001, The National Transport Policy was formulated. This policy is directly related to clean transportation system. In 2003, the National Ambient Air Quality System for various air pollutants was established. Two-stroke three-wheeler vehicles were banned from 2004 in the Kathmandu Valley. Government closed Himal Cement Factory to control the air pollution which was situated near the valley.(Source Dahal, 2006)Government has formulated and applied many rules and regulations to address the air pollution of Kathmandu valley, but the graph below shows that the main air pollutants Total Suspended Particulates (Particulate matters) is increasing every year.(Source MoEST Report 2006)5.3. Strength and weakness of t hese institutional changesIt is found that reforms in existing institutional set up is likely to bring some positive impact on the air quality of Kathmandu valley. Removing two stroke vehicles from the valley have reduced the air pollution as well as noise pollution. It has also helped to reduce the energy consumption because the two stroke vehicles use more fuel than other. However, the rules and regulations are no implemented because of the political instability and corruptions. The economic condition of the country has also impacted on the implementation the institutions because the government has not allocated sufficient fund for environment. In Nepal there is separate ministry dealing with environment (Ministry of Environment), however, the establishment of the local authority like environment department and its associated regional and district bodies, to effectively deal with the problems related to environment has not been materialized yet, even after more than a decade has p assed with the establishment of environment ministry. The establishment of environment department is still in the stage of planning and government has made efforts to establish it in near future, but according to the government financial constraint
