Life Cycle Analysis Of Paper Production Environmental Sciences Essay

Life Cycle Analysis Of Paper Production Environmental Sciences Essay During the typical life of a product, it will progress through 5 stages . At each stage there is interaction with the environment. In many cases the material processing and manufacture will occur in the same factory. The interaction between the product and the environment can be direct or indirect. For example, the pulping of the wood into paper will release emissions that are directly related to the paper. On the other hand, the transport of the paper will have an environmental impact from the emissions of the vehicle however this emission does not come directly from the paper. A Life Cycle Analysis (LCA) takes these emissions into account as well as other environmental impacts such as the destruction of habitat and can be used to quantify the environmental impact of a product from its original raw materials to its eventual fate (cradle to grave). The whole life cycle has to be considered, as the environmental impacts of different products will be greater at different parts of the c ycle. For example, paper will have a bigger environmental impact during the material extraction and material processing stages than it will for the use stage of its life cycle. However, an electrical item such as a washing machine will cause most of its environmental impact during its use stage because of its consumption of electricity, the majority of which are generated by the burning of fossil fuels. The life cycle must also consider the potential for the product to be recycled, remanufactured and reused. Reusing obviously has the lowest environmental impact as it requires less energy to convert the useless product into a usable product again. life cycle.gif Figure 1: The product life cycle showing the five phases and the potential to recycle, remanufacture and reuse products (Tarr, c. 2007) Paper is an essential product that the modern world relies upon. It is a highly functional product and is used to fulfil a variety of functions. It can be manufactured into many practical goods, with varying properties. It may be combustible or be made fire-resistant. It may be a carrier or a barrier or a filter. It may be tough enough to withstand acid or soft enough for a babyà ¢Ã¢â€š ¬Ã¢â€ž ¢s skin (Confederation of Paper Industries, 2010). Paper is a multipurpose commodity that can be used utilized to do anything from being printed on to deliver daily news to the masses, to create bank notes or even to make air and oil filters for cars. The worldwide consumption of paper in 2007 was about 300 million metric Tons (PaperOnWeb, c.2007). An LCA is a way of linking the inputs and outputs of any product to the environment and provides an insight into possible solutions to lower the environmental impacts of that product. A typical paper production process and each stageà ¢Ã¢â€š ¬Ã¢â€ž ¢s environmental impact are shown in figure 2 (below). recycling paper.jpg Figure 2: shows the stages in the life cycle of paper: the logging of wood in the forest and the environmental impact of this, its conversion to fibres, the processing of the fibres to make paper, the distribution of this paper to the consumers, the collection of waste paper, after which it is either recycled back into paper fibres or it is removed from the cycle and sent to incineration or landfill. Adapted from (Axel Springer, 1998) The paper industry uses a great deal resources and as waste paper is continually removed from the process, the paper industry is only viable if fresh fibres are constantly added. This means that trees have to be persistently cut down and removed from forests. This could lead to unwanted climate change due to their being less trees to absorb the CO2 and from the emissions from the manufacturing process and from the vehicles that are transporting the raw material. This wood could also have been used to generate energy, so removing it to create paper could lead to energy depletion. The trees used to produce paper should only be purchased from companies that will ensure that the trees are harvested and grown in a sustainable manner, as deforestation of local forests is unacceptable. If the trees were not harvested in a sustainable manner, and the trees were removed and not replaced the soil that would normally be held in place between the trees could be washed away when there is rainfall . During periods of exposure to the sun the soil would be dried out and the nutrients would be removed from it. This soil erosion would cause the land to become useless. Non-sustainable management of the forests will cause a disruption of the water cycle reducing the biodiversity of the forest. The paper industry is a very energy intensive one so carrying out an LCA on paper would allow us to see how much damage is being done to the environment by the paper industry. If the LCA shows that the paper industry is causing a significant environmental impact, it could cause a campaign for conservation. Goals The goals of this LCA were to assess environmental impacts of paper produced in Portugal, which is mainly exported and consumed in Germany, in order to discover what processes contribute the most to the environmental impacts. The environmental impacts being considered are the global warming over 100 years, acidification, eutrophication, non-renewable resource depletion and photochemical oxidant formation. The secondary aim of this LCA is to compare the environmental impacts of paper production, if the market was changed from German market to the Portuguese market. Limitations The LCA is limited by a few factors; firstly there is no data on the effectiveness of CO2 sequestration, so it was assumed that the CO2 released from renewable energy sources balanced the CO2 absorbed by forest growth. Secondly, even though fibres are recycled it is not clear how many times the original fibres can be recycled before they are too short to form a decent product, so it has been assumed that the paper is recycled 4 times at most before being sent to landfill or being incinerated. Thirdly, the materials that were present in less than 1% (in mass) in 1 tonne of paper of 80 g/m2 were ignored. Finally, the construction and maintenance of equipment, machinery and buildings were not included in the LCA. Inventory Analysis The first stage of an LCA is to carry out an inventory analysis. Here the overall life cycle of paper and the inputs required to make it are split up into smaller sections which are then broken down into individual processes and outputs which can be analysed. The life cycle was split into; forestry, paper production, distribution, final disposal in Germany and final disposal in Portugal. This is shown in figure 3 (below). Input: Raw Materials: Wood, Water and Chemicals Energy: Coal, Diesel and Electricity Forestry Paper production Distribution Final Disposal Germany: Landfilling 17% Incineration 8% Recycling 75% Final Disposal Portugal: Landfilling 53% Incineration 18% Recycling 25% Composting 4% Output: Usable Products Paper By-products e.g. wood for domestic purposes Output: Environmental Impacts Airborne Emissions Water Effluents Solid Wastes Figure 3: A diagram showing how the life cycle of paper was split into forestry, paper production, distribution, final disposal in Germany and final disposal in Portugal and how the inputs and output interact with each stage. Each stage was now separated into individual processes so that an inventory analysis could be carried out. This is summarised in figure 4 (below), which shows all the materials used and links them to the processes that occur. Stages Processes Forestry E. globulus forest Pine forest Paper Production Pulp production Chemical production Energy production in the grid Transport of wood to the pulp mills then to the paper mill Transport of chemicals Paper Distribution Transport of paper to Germany Paper distribution in Germany Paper distribution in Portugal Final Disposal in Germany Landfilling Incineration Recycling Energy production in the grid Transport of wastepaper from the user to the several disposal alternatives Final Disposal in Portugal Landfilling Incineration Composting Recycling Energy production in the grid Transport of wastepaper from the user to the several disposal alternatives Figure 4: A table of the processes involved at each stage of the paper life cycle, adapted from (Dias et al., 2007) To complete the inventory assessment data on the growth and harvesting of forests in Portugal would have to be found. It would also have to be known whether the paper mills in Portugal import trees from Scandinavia, as this would then change the size of the emissions generated from transporting the raw material to the paper mills. However, as the raw material is coming from Scandinavia there is a possibility that the emissions could be lower because the average emissions of CO2 from an articulated lorry carrying a load of 40 tonnes is 2.68 kg of CO2 per litre/km, where as a the emissions from a ship carrying the same amount of material would only be 0.4 kg of CO2 per litre/km (Davies, 2003). This means the material brought in by shipping can come from nearly 7 times the distance that it can if it is brought by road and still only have the same amount of overall emissions. A disadvantage of shipping raw material to Portugal is that the trees will still need to be transported from the port to the paper mill. This would not generate a significant amount more of emissions if the paper mill was located near a port. However, if the paper mill is located far from the port, the environmental impacts of transport will increase. The amount of pulp produced and the emissions that producing the paper pulp release would also have to be found. If the pulp is bleached to make it whiter, then there will be additional emissions with respect to wastewater. The paper making process is a very energy intensive one, so data would have to be found on the energy requirements of the paper making machinery and equipment. If the paper mill used some of its useful by-products to generate its own electricity, this would also have to be taken into account, as it may reduce the emissions generated by the plant as it will require less energy from non-renewable sources. However, it could cause an increase in the amount of particulate matter dispersed in the air from the paper mill. The environmental impact from the transport and distribution of the paper would have to be considered. As the paper is distributed in both Portugal and Germany, the environmental impacts of the distances involved in the distribution would have to be accounted for. The average distance for paper distribution in Portugal could be considered to be 200 km, for Germany this could be considered to be 2700 km. The environmental impacts of the final disposal of the paper in both Portugal and Germany have to be considered, as the policy for dealing with paper waste varies with country. In Germany, it is deemed that 5.8% of the paper produced is retained as archives. Seventy five percent of the paper that is discarded in Germany is recycled, 17% is landfilled and 8% is incinerated (Dias et al., 2007). In Portugal again it is assumed that 5.8% of the paper produced is retained as archives. Of the paper that is discarded 53% is landfilled, 25% is recycled, 18% is incinerated and 4% is composted (Dias et al., 2007). Using this information the environmental impacts of landfilling, incineration, composting and recycling could be calculated. The environmental impacts of the transport required to transfer the used paper to the recycling facilities would need to be determined in order to gain a more accurate representation of the environmental impact of the paper making process. Impact Assessment The impact assessment gauges the damage that will be done to the environment by the paper making process. The categories that could be considered are global warming over 100 years (GW), acidification (A), eutrophication (E), non-renewable resource depletion (NRRD), and photochemical oxidant formation (POF) (Dias et al., 2007). Figure 5 (below) shows the impact categories and factors that affect them. The factors that affect the impact categories are non-renewable CO2, CH4, NO2, emissions that are generated from renewable and non-renewable energy consumption, as well as chemical oxygen demand (COD) and adsorbable organic halogens (AOX). impacts of paper.png Figure 5: A table showing the impact categories and the parameters that affect each category (Dias et al., 2007) Using these weighting factors and the data collected in Dias et al. (2007), both an inventory analysis and an impact assessment were carried out. Each graph shows the analysis for both the German market and the analysis if the paper was to only be sold to the Portuguese market. Figure 6 (below) shows the results of the inventory analysis. Figure 7 (below) shows the results of the impact assessment. The negative values for various categories and stages of the life cycle reflect the parts of the process which have beneficial environmental impacts. Figure 6: A graph showing the results of the inventory analysis (G = German market, P = Portuguese market). The FU is the functional unit, which in this study is 1 tonne of paper (Dias et al., 2007). Inventory analysis results The area of the paper life cycle that uses the largest amount of renewable energy is the pulp production. However, the negative contribution is larger for Germany as more of the waste paper is recycled in Germany than in Portugal. This shows that the production of paper from recycled fibres consumes much less energy than the production of paper from fresh fibres. The majority of the non-renewable energy is consumed by the paper making process. The amount of non-renewable energy consumed by paper distribution is also greater for Germany than it is for Portugal due to the fact that the paper mills are located in Portugal so the paper has a large distance to travel before it is distributed throughout Germany. The non-renewable CO2 emissions are in similar proportions to the non-renewable energy consumption meaning that the paper production is the major contributor to non-renewable CO2 emissions. The paper production and distribution are the main sources of NOx emissions due to the energ y used from the national grid and the transportation of the paper. The SO2 emissions are mainly caused by the paper production stage of the life cycle, due to the energy production. On-site energy production provides a small negative contribution for NOx and SO2 emissions in Germany. The pulp production of the paper making process causes the largest contribution to COD emissions; however by recycling paper the final disposal stage can provide a slight negative contribution. Due to the chemicals used in the bleaching process of the pulping stage the AOX emissions are mainly created from the pulp production. Again from recycling the paper the final disposal stage can provide a negative input. Figure 7: A graph showing the results of the impact assessment (G = German market, P = Portuguese market) (Dias et al., 2007) Impact Assessment The most significant contributor to global warming in Germany is the paper production due to the high non-renewable energy usage and CO2 emissions. However in Portugal it is the final disposal that has the largest impact on global warming, as most of the paper waste goes to landfill which produces a lot of methane. As the paper production requires energy which produces high SO2 emissions, it is this part of the process that contributes most to acidification. The high COD and NOx emissions mean that the pulp production stage is the greatest contributor to eutrophication. A large portion of the eutrophication potential is down to the NOx emissions released due to the paper production stage. The electricity used during the paper production stage is the main contributor to the non-renewable resource depletion. Recycling the paper provides a positive impact to acidification and eutrophication, due to less material being sent to landfill and so fewer trees have to be removed from the forests. The amount of acidification, eutrophication and non-renewable resource depletion is greater for paper distribution in Germany due to the fact that the paper mills are located in Portugal so the paper has further to travel before it is distributed throughout Germany. The disposal of paper into landfill causes the release of CH4 which is a major contributor to photochemical oxidant formation. As Portugal sends more if its waste to landfill the impact of POF is greater. Conclusions The inventory analysis shows that Portugal consumes a larger amount of renewable energy and has higher emissions of SO2, COD, and AOX than Germany, this is due to the larger amount of paper sent to landfill. Therefore to change from the German market to the Portuguese market is less environmentally beneficial. However, the impact assessment shows that the acidification, eutrophication and NRRD are smaller for the Portuguese market due to the reduced transport required to distribute the paper. The pulp and paper production stages are major contributors to all the categories and environmental impacts due to the large energy requirements that are satisfied by both on-site energy production and consumption of electricity from the grid. From carrying out this LCA it has become apparent that the forestry stage does not provide any significant environmental impacts. Paper consumption in Germany is more damaging environmentally in categories in which the paper distribution stage has a consid erable input due to the large distance that has to be covered in order to distribute the paper. However, due to the smaller amount of recycling that occurs in Portugal, the global warming potential and photochemical oxidant formation are greater. This LCA has shown that the best area of the life cycle of paper to approach in order to reduce the environmental impact of paper manufacture is the pulp and paper production stages. The environmental impact could be reduced by more efficient treatment of flue gases and liquid effluents.

Poverty and Education

OMAR BANDEH # 2122369 ENG 102 PROFESSOR LAWSON Topic Outline Thesis: Education is the most powerful weapon that can bring positive changes in a society. I. Empower an individual to be a model citizen A. Educate him about his Rights B. Develop his self esteem II. Poverty alleviation A. Wide range of job opportunities B. Living standards increased C. Reduction in crime rate III. Eradicate Disease A. How to avoid it B. How to treat it C.How to live with it THE IMPORTANCE OF EDUCATION IN A SOCIETY Every nation especially third world countries should invest a substantial amount of their budget on education for it is the most invaluable asset that could transform an entire society. It was said by Aristotle that educated men are as much superior to the uneducated as the living are to the dead† if that is so then an uneducated society is as good as a dead society.After all education is the most powerful weapon that can bring positive changes in a society, it is the only weapon that can empower an individual in particular and a whole society in general, alleviate poverty and eradicate disease. The foremost aim of education is to empower an individual to be a model citizen and for that to happen he must know his rights and responsibilities. Without education, man is a splendid slave knowing not the difference between good and bad or his rights such as his freedom of speech, worship and movement, for only the educated are free.Free to make decisions, to face life, and to accept successes and failures. More over education is the only tool that can develop one's personality, his self esteem and confidence for it is a combination of these that gives a person the ability to stand up against tyranny and oppression of any form. In a complex modern democracy, citizens must be educated for them to be able to participate in a nation’s democratic and developmental process.For example if Nelson Mandela was not educated he would not have been able to challenge the aparth eid government thereby helping to bring it, to its end and in the process making the whole of South Africa free and colour blind. Secondly, the role of education in poverty eradication is crucial. There is overwhelming evidence that education is the one tool that children from poor families can use to break the cycle of poverty in which they are born in.A poor farmer’s son has the same opportunities to that of a president’s son if he is educated, for education provides the knowledge and skill with which an individual can use to get a job and earned a living on his own. It is only with an affordable education that a society’s poverty can be reduced and its living standards increased. And because poverty is a multidimensional social problem once it is taken care of, high crime and prostitution rates will dramatically reduced. Finally, disease, the one thing that can decimate an entire society especially an uneducated one.For education provides knowledge about dise ases, how to treat them and most importantly how to avoid them. For example diseases such as HIV/AIDS have blighted entire societies in places like Uganda and South Africa before people knew what it is and how it can be avoided. Now, after much sensitization the rates of HIV/AIDS infection have reduced dramatically and those already infected have been adequately educated on how to live with the disease in such a way that life expectancy of an Aids patient have increased compare to before.In addition, the availability of education in a society informs them the use of being hygienic and how to maintain high hygienic standards such as washing one’s hand after using the toilet and also before eating which has help to reduce the prevalence of diseases such as cholera and diarhoea. Therefore, to conclude, the impact of investing in education is profound for it is the only tool that can positively change a society by empowering it, lifting it out of poverty and most important of all enabling its people to live longer healthily.

A Health Profile Of The Country Of Malawi Essay - 1649 Words

The purpose of this paper is to create a health profile of the country of Malawi identifying the state of the overall health of the country based on specific health issues. Malawi has a population of 15,263,000. The average lifespan for males is 44 years and the average lifespan for females is 51 years. The leading causes of death in Malawi are HIV/AIDS, Lower Respiratory Infections, Malaria, Diarrheal Disease, and Perinatal Conditions. Infant mortality has a rate of 58 deaths for every 1,000 live births (Bowie, 2006). The Malawi Government has been consistently looking for ways to improve the public health including maintaining a budget for disease prevention and control. The Government has also teamed up with the Ministry of health to create a Health Services delivery system in Malawi to address the needs of treatment and care of patients (CDC, 2016). Together the government and Ministry offer services to the community through Health centers and Hospitals, and also through community based educational services. They have set up Health Surveillance Assistants (HSA) to help create a connection to the community. The HSA conduct health education services, immunizations, and other services. The two main health service providers in Malawi are the Malawi Government and then the Christian Hospital Association of Malawi (CHAM). The government health facilities are responsible for about 60% of the health services while the CHAM accounts for about 35% (CDC, 2016).

Cantwell v. Connecticut (1940)

Can the government require people to get a special license in order to spread their religious message or promote their religious beliefs in residential neighborhoods? That used to be common, but it was challenged by Jehovahs Witnesses who argued that the government didnt have the authority to impose such restrictions on people. Fast Facts: Cantwell v. Connecticut Case Argued: March 29, 1940Decision Issued: May 20, 1940Petitioner: Newton D. Cantwell, Jesse L. Cantwell, and Russell D. Cantwell, Jehovahs Witnesses proselytizing in a predominantly Catholic neighborhood in Connecticut, who were arrested and convicted under a Connecticut statute banning the unlicensed soliciting of funds for religious or charitable purposesRespondent: The state of ConnecticutKey Question: Did the Cantwells’ convictions violate the First Amendment?  Majority Decision: Justices Hughes, McReynolds, Stone, Roberts, Black, Reed, Frankfurter, Douglas, MurphyDissenting: NoneRuling: The Supreme Court ruled that statute requiring a license to solicit for religious purposes constituted a prior restraint upon speech violating the First Amendments guarantee of free speech as well as the First and 14th Amendments guarantee of the right to the free exercise of religion. Background Information Newton Cantwell and his two sons traveled to New Haven, Connecticut, in order to promote their message as Jehovahs Witnesses. In New Haven, a statute required that anyone wishing to solicit funds or distribute materials had to apply for a license - if the official in charge found that they were a bona fide charity or religious, then a license would be granted. Otherwise, a license was denied. The Cantwells did not apply for a license because, in their opinion, the government was in no position to certify Witnesses as a religion - such a decision was simply outside the governments secular authority. As a result they were were convicted under a statute which forbade the unlicensed soliciting of funds for religious or charitable purposes, and also under a general charge of breach of the peace because they had been going door-to-door with books and pamphlets in a predominantly Roman Catholic area, playing a record entitled Enemies which attacked Catholicism. Cantwell alleged that the statute they had been convicted under infringed upon their right to free speech and challenged it in the courts. Court Decision With Justice Roberts writing the majority opinion, the Supreme Court found that statutes requiring a license to solicit for religious purposes constituted a prior restraint upon speech and gave the government too much power in determining which groups were permitted to solicit. The officer who issued licenses for solicitation was authorized to inquire whether the applicant did have a religious cause and to decline a license if in his view the cause was not religious, which gave government officials too much authority over religious questions. Such a censorship of religion as the means of determining its right to survive is a denial of liberty protected by the First Amendment and included in the liberty which is within the protection of the Fourteenth. Even if an error by the secretary can be corrected by the courts, the process still serves as an unconstitutional prior restraint: To condition the solicitation of aid for the perpetuation of religious views or systems upon a license, the grant of which rests in the exercise of a determination by state authority as to what is a religious cause, is to lay a forbidden burden upon the exercise of liberty protected by the Constitution. The breach of the peace accusation arose because the three accosted two Catholics in a strongly Catholic neighborhood and played them a phonograph record which, in their opinion, insulted the Christian religion in general and the Catholic Church in particular. The Court voided this conviction under the clear-and-present danger test, ruling that the interest sought to be upheld by the State did not justify the suppression of religious views that simply annoyed others. Cantwell and his sons may have been spreading a message that was unwelcome and disturbing, but they did not physically attack anyone. According to the Court, the Cantwells simply did not pose a threat to public order merely by spreading their message: In the realm of religious faith, and in that of political belief, sharp differences arise. In both fields the tenets of one man may seem the rankest error to his neighbor. To persuade others to his own point of view, the pleader, as we know, at times, resorts to exaggeration, to vilification of men who have been, or are, prominent in church or state, and even to false statement. But the people of this nation have ordained in the light of history, that, in spite of the probabilities of excesses and abuses, these liberties are in the long view, essential to enlightened opinion and right conduct on the part of the citizens of a democracy. Significance This judgment prohibited governments from creating special requirements for people spreading religious ideas and sharing a message in an unfriendly environment because such speech acts do not automatically represent a threat to public order. This decision was also notable because it was the first time that the Court had incorporated the Free Exercise Clause into the Fourteenth Amendment - and after this case, it always has.

The Mandatory Minimum Sentencing Laws - 1613 Words

Current mandatory minimum sentencing laws are in dire need of reform. A mandatory minimum sentence is a court decision where judicial discretion is limited by law. As a result, there are irrevocable prison terms of a specific length for people convicted of particular federal and state crimes. As of January 2014, more than 50 percent of inmates in federal prisons are serving time for drug offenses, and more than 60 percent of people incarcerated are racial and ethnic minorities. The use of safety valves and implementation of the Fair Sentencing Act are a few methods Congress employed to combat racial disparity in prisons. Mandatory minimum sentencing harshly punishes non-violent offenders, disproportionately affects minorities, and skews the balance of power between judges and prosecutors. Throughout the majority of the 19th and 20th century, federal trial judges had a great deal of unlimited sentencing discretion. Unrestrained discretion can lead to sentencing disparities in particular cases, such as drug possession crimes. In 1952, the United States Congress enacted the Boggs Act, one of the first instances of mandatory minimum sentencing. Under the Boggs Act, the possession of marijuana, cocaine, or heroin carried a mandatory minimum of two years with a maximum of five years in prison. Nevertheless, in 1970, the United States Congress revoked the mandatory minimum sentencing for cannabis offenses.

Technological Advancements Are Being Taking-Myassignmenthelp.Com

Question Discuss About The Technological Advancements Are Being Taking? Answer: Introduction Technological advancements are being taking place in every business sector at an extremely rapid rate. Internet of Things (IoT) is one of the examples of the latest developments that have been done. IoT refers to the working of a varied number of elements such as computing devices, electrical applications, databases etc. through an inter-networking medium that is Internet. The goal of each of the elements that are involved in a particular IoT application is common. There are various entities that are working on different IoT projects currently (Rose, 2015). Microsoft along with Schneider Electric came up with one such project in the agriculture field and termed it as Kiwi IoT project. Problem Definition Every country has agriculture as one of the major activities that are performed. A large share of water and mineral resources are used in the activities that are associated with agriculture. There are several issues that come up in terms of farming methods, monitoring and control, gathering of information etc. that are involved in the process. Waterforce is an organization that brought a solution to such issues with a cloud based IoT system carrying out latest analytics and remote monitoring to execute sustainable farming (Itbrief, 2017). Application of IoT in Agriculture Solution Features The system is scalable in nature Cloud-based Mobile capabilities are provided Detailed analysis of the watering plants that are involved Compliance check with the regulatory processes Remote control and monitoring of the agricultural activities Data collection and analysis to understand weather patterns Adjustments of the irrigational activities as per the weather situations Backing up of the data Smart farming Processes Working of the Project The solution that is designed by Waterforce in collaboration with Microsoft and Schneider Electric has been termed as SCADAfarm. It is a water management and irrigation organization system that makes used of the IoT platform that has been developed by Microsoft Azure. The framework that is used in the system is provided by Microsoft in the form of its hub services. The software, hardware along with the technologies that have been implemented have been contributed by Schneider Electric. It makes use of the cloud based architecture including several sensors, controls and automated speed driving equipment (Zheng, 2017). Pros and Cons Currently, the solution has already been implemented in various farms across New Zealand. The primary aim of the system is to support sustainable environment with the aid of environment friendly farming practices. The system makes use of extensive water logistics and pumping uphill to ensure that the steep terraces are provided with adequate water supply (Chen, 2014). The management of the farms with the use of traditional farming equipment and the traditional practices is not applicable anymore. Also, it possesses a lot of risk for the environment as well (Evans, 2011). SCADAfarm, therefore, enriches the practices and procedures that are followed in the farming activities. The following benefits are provided to the users with the installation of the IoT system. The system allows the remote monitoring to be carried out in association with the irrigation pumps that are used in the farms The operations that are executed with the aid of the irrigation pumps can also be done remotely The system allows the customization activities to be done for every category and type of the crop Customization and suggestions are also provided on the basis of other factors such as type of the soil along with the level of moisture that is present The system gathers the real-time data from the weather stations to provide recommendations on the practices that shall be applied on the basis of the weather condition There are, however, a few cons that are also associated with the IoT system. The main drawback that exists is the cost that is associated with the system. The cost of the equipment along with the deployment and maintenance cost is considerable. There is also a frequent update of the system that is required to be done to make sure that there are no flaws and defects present. There may be technological guidance that may also be necessary to understand a few features and functionalities. There is assistance and support included in the system; however, the user may get stuck in certain scenarios. Conclusion IoT applications have the ability to add a lot to the utility of the users along with the other benefits in terms of ease of usage, inclusion of automation and so on. The IoT system that has been described above also offers many benefits in the form of environmental advantages as the system supports conservation of resources and also carries out sustainable farming (Miorandi, 2012).
