Environment Primary Factor That Influences Plant Growth Development Biology Essay

Environment Primary Factor That Influences Plant Growth Development Biology Essay Although there is no doubt that the world population grows up in more gradual way every year, demanding more food than any other time before, Environment is the primary factor that influences the plant growth and development and has also the greatest effect on the crop distribution on the earth. In this ten page report, the most important environmental factors that affect the crop growth and development namely light, water, temperature and carbon dioxide are covered, emphasizing their influences on crop productivity. Moreover light as the most environmental factor importance on crop production and productivity, all light quality, quantity and duration effect directly on crop yields, also in most cases plant reactions and processes are greatly influences by the temperature, plants key process affected by temperature is photosynthesis followed by germination, transpiration, respiration and flowering. However, crop temperature requirements in a specific physical, chemical or biochemical process varies from one spice to another resulting difference among crops in their geographical distribution. On the other hand, water and humidity play an important role for the crop productivity since most plants need 90% water content to grow effective and efficiency way until some crops like rice demand flooding the area to grow properly. In addition to the plant water needs, plants are number one consumers of carbon dioxide on the earth so as to synthesize food and energy. Each of these factors were discussed in this report emphasizing and giving more detailed look on their effect on crop productivity. Light Why solar energy is important to a successful plant growth, development and improvements to its yields? On the planet life is mostly solar-powered, sun is the only natural source of light energy, all the living organisms depend on the amount of light energy (solar radiation produced by the sun) harvested by green plants at any level of ecosystem, only few types of bacteria can derive the energy they require from sulfur and other inorganic chemical compounds or substances. Photosynthesis which is the process that the plants manufacture their food molecules from carbon dioxide and water by using the sun light, therefore the rate of duration of photosynthetic activities directly effects the amount of dry matter produced by the plant, and energy harvested as crop yields to transfer energy from primary producers to the other components of the ecosystem which are the consumers, so the ultimate source of food in the globe is the green plant, because plants have the ability to harvest and ut ilize the sun light manufacturing a usable food after three main consecutive processes during plants photosynthetic activities. Photosynthesis The management of that resources available to the production, that the crop requires to grow and develop and show its potential genetic characteristics as much as possible is a major factor that contribute the dramatic rise of the crop production, only organisms/plants that contain a certain pigment called chlorophyll which is the most abundant enzyme/protein on the earth are capable to utilize solar energy directly. It is therefore; light is an important factor to produce energy by the plants and the energy produced will be supplied to the different levels of the ecosystem. The light influence on the plant development and productivity can be discussed into three main categories. Quality of light The intensity of light and its concentration are what decide the quality of light; light densities differ from one season to another, countries that have three or four seasons, the largest amount of light is found in the summer season, where the least amounts are available in the winter, as the case is in many European countries, but areas like Malaysia the amount of light available throughout the year is almost the same, so the light intensity varieties depend on the geographical area, for example in Sub-Saharan Africa where the climate is desert, clouds and other sun light barriers are not found in the atmosphere, the sunlight density is very high. Not straying from the main point, the more light radiation that a plant harvests, the greater and the ore ability to manufacture food through photosynthetic processes even though this relationship will depend on the pathway group that a certain plan flows. From this interactions, the scientists specially those botanists, ecologists and physiologists realized the direct relationship the amount of light available to the plant and the crop productivity, that is why the greenhouse managers to fix artificial light sources to supply light their fields to create longer photoperiod in the greenhouse targeting more improvements to the final output, even though this strategy will negatively affect the cost of every unit produced under this system. However, they can easily manipulate the amount of light of the planned growth patterns to their plants. Quality of light Are there different light qualities? Light colors, which can be divided into bands of red, yellow, blue, orange, violet and indigo. The red and blue color lights that the plant can absorb have the biggest influence on crop growth, the blue light is primarily responsible to the leaf vegetative growth and the combination of red and blue lights encourage the flowering process. The solar rays produced by the sun, or what is normally known as wavelength of the light constitute the light quality, wavelengths that the sun sends to the earth ranges 250 7000 nanometers, these solar rays reaching the earth are divided into eight parts, only the visible radiation is called light, and the other which are Cosmic rays, Gamma rays, X-rays, Ultraviolet, Infrared, Microwaves and Radio waves are invisible. The visible solar rays or light is the small proportion of the range of wavelengths of the electromagnetic radiation occurring somewhere between 400 and 735 nanometers. In other words the visible light is between Ultraviolet which are shorter waves than 390 nanometers and Infrared which are longer waves than 700 nanometers. Only 47% of the light produces by the sun is gained by the earth (P. Bannister 1978), where the other 53% part of it is absorbed by the atmosphere while other part is reflected by some barriers and finally gained by the space. Only 2% of that 47% o f the light that reaches the ground is used in the photosynthetic processes and about 10% is used different processes that occur in the plant. Duration of light Photoperiod or the duration of light is referred to how long of time the plant exposes to light, the flowering of many plant species is controlled by the photo duration, as a result that, the plant physiology experts tend to name and classify plants into short-day and long-day plants relating to under which condition do these crops flower. In contrast, the duration of uninterrupted darkness which presents a critical situation to the crop development and flowering process is the factor that show the importance of light duration not only the plants but also on farm animals specially poultry production therefore shorter darkness periods are encouraged. The amount of carbon dioxide fixed and assimilated by a specific plant is determined by the light density, because several situations can be seen when the plant is grown the area where the light intensity is not constant this is much explained in the plants light response curve, which shows light compensation point, plant light response area and plants light saturated period where any further increases of the light available to the plant will not result an increase in the amount of the carbon dioxide absorbed from the atmosphere, meaning photosynthetic activities will peak t that point and all the enzymes involved to this process are active. From this concept, the ecologists realized some remarkable differences among the two main pant pathway groups C3 plants, C4plants. Because the carbon dioxide concentration is not the same in these pathways as soon as there are variations in amounts of light available (lower, neutral and higher) the different light amounts are available to the cro p, the growth, development and productivity are highly effected by the light factor. In addition to that, C4 plants showed higher net rate of photosynthesis as a result of light intensity increases than C3 plants. Even though at a very low light intensities C3 plants are more affective and efficiency than C4 plants because of their low compensation points, crops like corn and sorghum full sunlight for photosynthesis while tobacco can tolerate only partial sunlight. Water Water is the most component in the living cell, plants contain nearly 90% of water content , this high percentage enables us to understand the remarkable role of water on the crop growth and development, large quantities of agricultural output all over the world is heavily depend on different types of irrigation, over 1500 million hectares of agricultural land are irrigated every year, the continuously rise of the global temperature is seem to be the highest impact on the irrigated agriculture when considering water (hydrological) cycle. Water in a primary component in plant photosynthesis, the plant respiration, responsible to balance the pressure (turgor) in the plant cell, turgor is required to form the cell shape, tissue firmness and fullness, and ensure cell development. Also water is the place and the solvent where carbohydrates and minerals are transported from the soil and/or leaves to the other parts of the plant. Water treats as a cooling system to regulate the plant temperature specially on the leaf surface through a process called transpiration, water controls the stomata opening and closure, water provides a kind of power to encourage roots to penetrate the soil more in depth and this will enlarge the space that the crop can absorb the nutrients needed for growth and development. One more crucial role is that the water is the medium where biological reactions take place, also water is a component in the organic reactions, and it is used in the cell growth. Amount of water available in the plant compared the atmosphere water content (atmosphere humidity) is the limiting factor of crop photosynthesis, the ratio of the amount of water vapor available in the air to the volume of water that the air can keep at specific temperature and pressure is called relative humidity. Water vapor is the whenever a water molecule leaves from the surface of the ground, it is said to have  evaporated. Each individual water molecule which transitions between a more associated (liquid) and a less associated (vapor/gas) state does so through the absorption or release of kinetic energy. On the other hand, In the hot climate, wind and dry air conditions while there is a moisture stress or what scientifically called water deficit caused by the low water content, in this situation the stomata aperture is dramatically reduced and the photosynthetic reactions are weakened because the activeness and the effectiveness of the enzymes have a direct proportional relationship to the amount of water found from the s urrounding environment and inside the plant tissue and indirectly proportional to the temperature specially the extreme one. Temperature As said in the beginning temperature is important factor to the plant growth, development and yield, since it affects approximately most of the plant processes including germination, photosynthesis, respiration, transpiration and flowering. As the degree of temperature increases this will result an increase to the plant respiration and photosynthesis. Generally in temperate species, the increase in temperature about 10oC (18oF) will cause to the rate of carbon dioxide (CO2) assimilation approximately to double. Furthermore usually plants in the tropical areas require higher temperature degrees to perform successful photosynthetic processes to the possible maximum level that the plants in the temperate areas can generate. Usually, plants differ their temperature requirements for example radish, spinach and lettuce which are cold weather (season) crops germinate at 55oF 65oF best, where crops like petunia, lobelia and tomato which are hot climate crops germinate at about 65oF 75oF best. According to the level of the temperature, plant processes can speed up or slow down the period that each activity completes. For instance, the 18 months that the oil palm plants need to live in the nursery can be reduced to about 10 months when provided higher temperatures from artificial sources. Flowering however, experts in horticulture sometimes relate the length of the day to the temperature to manipulate flowering. For example the combination of short days with low temperature degrees helps cold-season plants to the set the flowers as the case in Christmas cactus, when the temperature levels are in their highest points and the days are in their longest hours the summer (cold-season) crops will bolt as in the case in spinach. In contrast, when the temperature is extremely cold, plants like tomato which is warm climate crops will set their fruits in unsuccessful manner. Temperature influence on biochemical plant processes Biochemical reactions of the plant are directly affected by the temperature through one or two principle functions, an exponentially dynamic increase to the rates of proceeding activities. And sometimes as the climate gets hotter more exponential delay will be experienced resulted by enzymes lost their naturalness. The most important and involved factor is the weather, it is not impossible to rise the quality of enzyme stability so as to avoid losses in their naturalness. The everyday changes on the temperature is called thermo-period the best crop growth occurs when the difference between the day and night temperatures is about 10 to 15o C. under this situation plant build up their food and break down the energy, higher temperatures than that required by the crops cause some crops to photo-respire and the amount of food manufactured by the photosynthesis will equalize the energy used to at that time and carbon dioxide CO2 assimilated will be zero meaning that the crop is in the state of light compensation point. Therefore food molecules synthesized from the photosynthetic activities must overweight the energy that the plant consumes otherwise the plant will grow poorly resulting drops in the ultimate yields. Higher temperatures and their long-term influences on the crop The chronic effects meet the crop growth and development when the temperature is getting higher every day the crop stress will become more serious because of the extreme hot weather. However C4 plants showed a higher net rate of photosynthesis than C3 plants when temperature levels at the surface of leaves were increased. In 1993 Kropff and his colloquies, found that 9% decrease of rice productivity were recorded for every 1o C increase of the temperature, the Intergovernmental Panel on Climate Change (IPCC) coordinating with the Food and Agricultural Organization of the United Nations (FAO), their second evaluation report in December 1995 forecasted that the temperature of the planet will rise about 2 5oC during 21st century and the sea level will grow up about 30 t0 100 cm more, and this higher sea levels can submerge many agricultural areas in the world, these weather conditions will negatively affect the food production in the globe. Carbon dioxide When crops are manufacturing their food through photosynthesis, carbon dioxide is the most component factor importance in that process, plants obtain CO2 from the air through the pore spaces on the surface of the leaf when open, CO2 flow in the plant tissue depends on the carbon dioxide concentration inside the plant and the plants surrounding atmosphere, the carbon dioxide molecules (substances) move inside the plant when the concentration inside is less density than its concentration outside and this is a physical process called diffusion. The carbon dioxide flow in the plant is controlled by the stomata then the pore spaces on the leaf surface are open, and the aperture of the stomata its turn depends on the amount of water available in the guard cells. Overview of carbon dioxide influence on plant growth and development Plants are divided into two main categories according to their response and their first stable product after the fixation of carbon dioxide. The first category is those species whose first stable products after the fixation of carbon dioxide is three carbon molecules and the plants under this group are called C3 plants or C3 pathway. The second group is the species that their first stable products after the fixation of carbon dioxide are four carbon molecules and plants in this group are called C4 plants or C4 pathway, also there are CAM plants, these plants have different character, because the plant here operate fixing carbon dioxide in dark, plants depend on the amount of carbon dioxide accumulated in the leaf in the night. The photosynthetic rates of the plant directly relate to the growing amounts of carbon dioxide until it reaches approximately 700 ÃŽ ¼ mol/mol or higher according to the plant type and other factors. Furthermore photosynthesis always develops with the rise of temperature to optimum levels and after specific maximum level the photosynthesis in C3 plants show decline, as a result of photorespiration process which takes place in the plant. As some scenarios of the world climate change mentions, a global worming is forecasted and that will increase the amount of carbon dioxide available in the atmosphere as well as other gases in the green house. Mean while the amount of rain in many places of the world may also experience changes, generally scientists believe that certain plant species will indicate yield increase especially in C3 plants (C3 pathway includes many important crops like wheat, rice, oats, soybean, pea, peanuts, sunflower and tomato) because of the CO2 increase. However, benefits of increased carbon dioxide concentrations in the atmosphere are limited, because stomata close and photosynthesis stops at CO2 concentrations higher than 0.15%. On the other hand, C4 plants which include coin, sorghum, sugarcane and millet and many other crops are more efficient in higher bright-nesses and higher temperatures than C3 plants even though the reverse is true when light intensity is very low. Soybean responses different amounts of CO2 As IPCC and FAO reported in their second assessment in December 1995, the amount of production harvested from soybean fields was generally increasing by the elevated CO2 levels Allen et al. (1987). The following table shows the percentage increases of soybean yield predicted across selected carbon dioxide concentration ranges associated with relevant benchmark points in time, adapted from Allen et al. (1987). Period of time (years) [CO2] midday Biomass photosynthesis Seed yield Initial Final (Nmd/mol) (% increase over initial [CO2]) IA 17001 200 270 38 33 1700 1973 270 330 19 16 1973 20732 330 660 50 41 1 IA, the ice age is about 13 000 to 30 000 years before present. The atmospheric CO2 concentration that prevailed during the last Ice Age, and from the end of the glacial melt until pre-pioneer/pre-industrial revolution times, were 200 and 270 ÃŽ ¼ mol/mol respectively. 2 The first world energy crises occurred in 1973 when the CO2 concentration was 330 ÃŽ ¼ mol/mol. This CO2 concentration is used as the basis for many CO2 doubling studies. The CO2 concentration is expected to double sometime within the 21st century. Conclusion Crop production and productivity entails the management of production resources, since the world population increases demanding more food and fiber the need of utilizing the sunlight energy, water, temperature and carbon dioxide is important since plants are the ultimate source of energy for all lives on the earth. We humans and other animals cannot utilize the solar energy, only organisms that contain chlorophyll are able, but we are capable to give more attention to the factors that affect photosynthesis. The management, conservation and protection of water, land and atmosphere are the most challenging issues to realize higher and stable crop yields. In the future, the main that the researchers discuss will be to identify and select plant species that have the ability to perform more photosynthesis and carbon dioxide assimilation for higher dry matter production. Also when more is understood from influences of the present climate changes on plant production and productivity, much money, time and effort should be invested to introduce cultivars that can adapt the environment biologically and systems to contribute the management of crop production to create more stable, sustainable and productive agricultural models.

Health Psychology Essay

Health psychology concerns itself with understanding behavior, biology and social context and their influences on illness and health. Health psychologists work with professionals in clinical areas and also conduct research as well as teach in universities. Health psychology aims at changing the health behavior of individuals to help them maintain optimum health and assist patients in adhering to treatment regimens. Adherence to medical regimens and shorter hospitalizations are indicators of effective health services. Health psychologists use cognitive behavior therapy and analysis of applied behavior to achieve this. Discussion The duty list is composed of activities that are aimed at improving the access of services to patients and also to improve the overall healthcare of patients. In assignment of duties to the various health professionals some health psychologists will receive more than one duty on the list. This is because of some of the duties which are closely related making it more reasonable for these duties to be carried out by one person. The list however has very many activities which if work load is considered makes it necessary to have a fifth job title. The fifth job title would be a communication skills counselor. The duties will then be allocated as follows, the substance abuse counselor will be responsible for coordinating the use of recovery programs and structured programs for substance. He/she will be working in conjunction with the social worker. The rationale behind this assignment is that the substance abuse counsellor is the person most appropriate for dealing with substance abusers in assisting them to get rehabilitated. The nature of substance abuse is such that it has social and psychological components to it so the collaboration between the substance abuse counsellor and the social worker is necessary. The patient load in substance abuse programs is high because of the intensive nature of behavioural change programs that are used, hence the substance abuse counsellor will only have this duty assigned to them. The inpatient-only psychologist will be assigned to the duty of providing treatment for chronic pain. The psychologist will be performing this duty only. This will be because of the large number of patients who have chronic pain. Managing these patients adequately means that the psychologist may not have enough time to attend to other duties. The child psychologist has two duties assigned to them. These are providing psychological preparation methods for children prior to medical procedures and collaboration with local schools. These are two duties which are closely related. By being involved with local schools the psychologist will already be familiar to the children making it easier for them to get children to cooperate when in the hospital. The adult psychologist will have the duty of providing psychological preparation methods for the adults prior to medical procedures and surgery. The workload for this psychologist is expected to be high since most of the patients are adults, hence the adult psychologist will only have this duty. The fifth job is that of communications counsellor, who will be carrying out duties of utilizing various methods to facilitate adjustment and coping skills amongst the patients. This psychologist will also have the role of diagnosing stress disorders and providing aid in stress relief interventions. The rationale behind this assignment is that the two duties are also closely related. The effect of poor adjustment to a condition and inability is often stress (Broome, Llewelyn and Llewelyn, 1994). Sometimes the relationship is vice versa, with high stress levels causing poor adjustment to one’s condition (Lyons and Chamberlain, 2006 ). The substance abuse counsellor will contribute to improved patient healthcare by provision of services geared towards behavior change that will enable the patient to be completely rehabilitated. The HBM (Health Behaviour Model) proposes that behavior change occurs when an individual perceives that the benefits of behavior change outweigh the costs or barriers that are associated with the behavior. (Friedman and Silver, ). The substance abuse counsellor will use such a model to predict the possibility of behavior change for the substance abuser. The usefulness of the HBM has been seen in its predictive value of whether individuals will adopt behavior such as safe-sex practices, breast self-examination and exercise (Friedman and Silver, ). The substance abuse counsellor will use cognitive behavioral therapy to educate substance abusers about the need to steer clear of drugs. Those with alcohol and other drug addiction problems will be helped to identify problems and behaviors that are related to their substance abuse. This will often be done in a group setting and occasionally on an individual basis (Occupational Outlook Handbook, 2008). Group settings are used mainly because many people feel encouraged by the fact that they are not alone in the addiction problem. Other activities that the substance counsellor will be involved in include assisting family members to cope with the addictions of their spouses, children or siblings. Since health psychology places emphasis on prevention of illness,the substance counsellor will have the responsibility of initiating, planning and conducting programs which are aimed at the prevention of addictions. This will help in the achievement of overall better health since it is often easier to prevent a condition rather than to cure it. The rehabilitation process for drug addicts has been known to be a difficult with many of them falling off the wagon. Thus a lot of time and patience is required, making prevention the better option. The emphasis on prevention is aimed at reducing the number of patients who will need to use substance abuse programs and also at reducing the rate of relapse. This contributes to decreased stay at the hospital. The child psychologist has a role of helping children to respond to the physician in a positive and cooperative manner at the time when a procedure is being done. This will involves the use of methods that allay the fears and anxieties of the child, such as providing distractions. The counsellor will also explain to a child who is old enough to understand the nature of the procedure they will undergo and what to expect in language that they can understand. The child counsellor will also have the responsibility of identifying cases of child abuse and other problems in the family that may hinder proper child development (Occupational Outlook Handbook, 2006). In addition, it is the role of the child psychologist to educate the parent(s) or the guardian of the child on the developmental milestones of the child and to encourage parents to bring their children to hospital if any of these milestones are missed. At the local school, the child psychologist will continue to observe children for any behavioral, social and personal problems. This will contribute to improvement in child health as it will result in early detection of problems and therefore early management and possibly shorter stays in hospital. The adult psychologist will be preparing adults psychologically for medication by telling the adult patient what to expect. Before surgery, the adult psychologist will visit the adult patient and discover what fears they may have. The adult psychologist can allay this by explaining the changes that the patient may expect following surgery or after a medical procedure. The adult psychologist can also communicate the patient’s worries and fears to the physician, surgeon and other health professionals directly involved in patient care. This will ensure that the medical professionals allay these fears and are conscious of them as they take care of the patient. This contributes to better healthcare because a less anxious patient is more cooperative and the patient is more likely to have greater adherence to their medication regimen. Management of chronic pain is a role which will include activities like administration of the McGill Pain Questionnaire to patients. This tool assists in description and measurement of pain (Marks, Murray, Evans et al, 2005). It provides a set of words describing pain from which the patient can choose from. These will assist the doctor to determine the intensity and depth of the pain that the patient feels. The McGill Pain Questionnaire makes diagnosis of pain easier and depending on the type diagnosed the appropriate medication can be prescribed, reducing the patient’s hospital stay. Another activity that the inpatient only psychologist will be involved in is confirming that a patient is safely using patient administered analgesia. This information can be elicited through conversations with the patient which will reveal their use of the analgesics that they have. Cognitive Behavioral Therapy (CBT)and biofeedback are other techniques of treating pain amongst inpatients. CBT involves the use of distraction and relaxation techniques (Scott and Briere, 2006). The use of CBT where the patient is advised to note pain relieving and pain aggravating factors also help in the management of pain. These are useful in managing pain and when the inpatient psychologist has taught these successfully to the patient then it becomes easier for the patient to handle the pain and stick to their medication. The overall effect of these is a shortened hospital stay. The communications counsellor will have a role in educating physicians on the importance of maintaining patient-centered consultations. These consultations as opposed to doctor-centered consultations make the patient to feel as though they are part of the treatment process. The doctor- centered consultation is perhaps preferred by the elderly but is disliked by most people due to the sense of ignorance that it seems to inspire. A patient-centered consultation focusses on the needs of the patients and allows the doctor to listen to the patient, involve the patient and finally make a diagnosis and choose treatment. Health psychologists believe that treatment that is arrived at like this has a higher chance of being adhered to (Marks et al, 2005). The communications counsellor will therefore make this known to the medical professionals to enhance adherence to medication regimens. This is important as often the way a patient is handled by the medical professionals influences their adjustment to a condition they have especially when the condition is chronic. Adherence to medication is an indication that the patient is well adjusted and is coping well. Most patients who have suffered traumatic conditions or who have chronic conditions are predisposed to management of stress disorders. Development of a stress disorder in addition to their chronic condition makes their health even worse and increases their period of stay in hospital. The communications psychologist will identify these patients and plan for and implement interventions that will help to relieve their stress. Some of these interventions include CBT, which can be done individually or in a group. The communications psychologist may also introduce biofeedback. Biofeedback involves the measurement of the functions of a subject such as heart rate, blood pressure, skin temperature and muscle tension as well as sweat gland activity (Scott and Briere, 2006 ). Often when a patient stress levels are increased these parameters tend to increase. When measured and an increase is found, the patient’s awareness is raised and the patient then can consciously begin to control the unconscious physiological activities. Adherence to this practice can help patients avoid thoughts and feelings which increase their stress. The communication psychologist will also encourage the patients to verbalize their feelings of anxiety and stress and what they think are the sources of the stress. She/he will then explore with them the things that they can engage in to help take away their stress. These include physical activities, board games, conversations with other patients. Some stress issues may be related to the family especially where a mother is sick. She may worry about the care of her household and children. To assist this mother, the communications psychologist may need to help the mother work out a plan for care of her household with other family members. Once the stressors have been identified and done away with the patient is more likely to heal faster and be more committed to their treatment regime. The role of the communications psychologist is very important in detecting patients who may go into depression as a result of stress associated with their conditions. Conclusion Some of the jobs of the health psychologists may seem to overlap. These include the jobs of the inpatient psychologist and the communications psychologist since both seem to be dealing with chronically ill patients. They also seem to have a similar objective in that they want to ensure that the patient adheres to their treatment regimen. There are similarities between both jobs, but the focus of the inpatient psychologist is the patient who requires pain management. Overlap is reduced by the fact that should the patient develop stress as a result of poor pain management then they can be referred to the communication psychologist. The communication psychologist will then go on to identify the stressor and put in place appropriate interventions. The overlap is not an entirely bad thing as it will result in some of the workload being shared among the psychologists since there is likelihood of patients being more in one psychologist’s speciality. The health psychologists described above will all be working towards improving the care of their patients. Most of the interventions that they will put in place will lead to either decreased hospital stay or greater adherence to medication. This effectively results in improved health among the patients.

Why Is Boko Haram - 1625 Words

Since the execution of Osama bin Laden and other al-Qaeda leaders, international terrorism seems to be on the decline with some even arguing that terrorism will end sooner than we expected. However, through waves of recent bombings, bloody kidnappings, and remorseless assassinations, Nigeria has proven that while terrorism may be on the decline, local terrorist groups seem to still be on the rise and the unprecedented terrorist operations of Boko Haram have shattered the hope that peace is returning to Africa’s most populous country any time soon (â€Å"Boko Haram†). Nigeria is a West African country with a population of about 170 million people. It is a country divided with religion and ethnicity. The country is made up of both Muslims and Christians, with an area called the middle belt bordering the Muslim north and Christian south (Ehwarieme). For many decades, Nigeria has witnessed various forms of violent conflicts. In recent times the activities of Boko Haram in Northern Nigeria has become the major source of crisis and fear in the country. About 13,000 people are estimated to have been killed in Boko Haram-related violence, making it one of the deadliest terrorist groups in the world. (â€Å"Boko Haram†).
