Best Economic Rotation of Various Farm Grown Tree Species

Best Economic Rotation of Various Farm Grown Tree Species TITLE: DETERMINING THE BEST ECONOMIC ROTATION OF VARIOUS FARM GROWN TREE SPECIES. Abstract The innovative knowledge relating to the excellent economic rotation of Dalbergia sissoo (Shisham), Acacia nilotica (kikar) and Albizzia lebbeck (Shareen) grown in the farmlands of Pakistan, is still inediquate and erratic. It should be calculated on tehsil level as the growing rate of trees differ from area to area controlled by climate. According to this requirement, the present study has been planned. Tehsil Kot Addu of District Muzaffargarh will be choosen for this study. 5 villages of Tehsil Kot Addu will be selected randomly. From selected villages five fields having an area of five acre will be selected through random selection technique. Common type trees growing there will be assigned successive numbers. Tree height diameter at breast height (DBH) will be measured. The price of every standing tree will find out from the land owner. The data will be arranged in tabular form, organized and discounted at appropriate discount rate. Return on investment (R.O.I), Benefit cost rat io (B.C.R) and Net present worth (N.P.W) will be used as economic tools. Various rotations of trees will be checked to discover the economic rotation of each tree species. V. INTRODUCTION Forest plants supply basic necessities of life (food, fiber shelter) to a great size of people. The population of the world is increasing day by day and is predicted to be about 10 billion in the mid of 21st century. As a result, wood and wood products demand will also increase manifolds (UNO, 1995). In Pakistan there is deficiency of about 29 million cubic meters of timber. The rate of deforestation is increasing continuously at a rate of 2.5% annually. Population increase rate is 1.90% per annum, if the same situation continues, urban population will be doubled in the next 20 years and will surly lead to more deforestation for making way for humanity (Government of Pakistan, 2005). It has been narrated that eighty to ninety percent of rural need of home fuel demands are fulfilled by fire wood, in the primitive countries. Forests have a huge importance in Pakistan’s economy by supplying timber, fire wood and shelter for animals (Nouman et al., 2006). It has been narrated that, total houses of Pakistan in 2006 were 22.8 million, from which Punjab has 54.85% (12. 280 million houses). Out of the total houses (22.38 Million) just 20% (4.476 million) units had been provided natural gas while 80% (17.904 million) were depending on the other energy resources as fuel wood, dried animals dung, residues of crop, Liquid Petroleum Gas (LPG), kerosene oil and charcoal (partial burnt wood) etc (Government of Pakistan, 2009). Nearly 32% energy demand is met by the wood biomass (FAO, 2009). As stated by Energy-Pakistan (2011) all the energy extracted from the informal energy means like mechanized waste, charcoal , residues of crops , cow dung, metropolitan waste and fire wood was 28Ãâ€"106 ton in 2008, from which 26.5Ãâ€"105 ton (95%) was acquired from fuel wood. This alarming situation had highlighted by (Government of Pakistan, 2005) which proposed that our forest resources will be destroyed in next 15 years due to huge deforestation for fuel wood and timber. Pakistan is at the 110th country in the world by his forest resources as announced in 2011 by United Nations General Assembly (Chaudhry, 2011). The world’s forest cover is about 30% whereas Pakistan has only 4.8% (4.2 million hectares) out of 88 million hectares (Anonymous, 2005). On the other hand, it is only 2% as stated by (FAO, 2011). Thus, Pakistan has the scant quality forest resources along with minimum ratio as compared to the world (Mcketta, 1990). Pakistan has 0.001ha per capita forest resources while in the world it is devoted 1.00 ha per capita (FAO, 2011) including small contribution of forest sector to our economy. Cultivation of trees with agricultural crops is an old method of obtaining various benefits from the same piece of land. Kalinganire et al., 2008) stated that Farm forestry is a beneficial combination of trees or woody plants with agricultural crops at the same land piece either in a chronological or longitudinal arrangement in such a way that both cost-effective and biological collaboration occurs between them. In Pakistan about 60% of timber and 90% of total fuel wood needs are acquired by the tree plants grown on farmlands. (Rahim and Hasnain, 2010). Land owners grow tree plants on their farms and they harvest them without any proper/optimum rotation. This may cause economic loss because inflation and market price strongly affects the farmer’s economic benefits. The present research has been planned to determine the optimum economic rotation of various farm grown tree species. It may lead the farmers to maximum benefit. All this needs to carry out at the gross root level (D istrict Tehsil level) because the tree growth rate strongly differs from place to place. Present research is lacking in literature. There is no any information available in the literature related to the best economic rotation of different farm grown tree species in Pakistan, Punjab at tehsil level. So, this study was planned with these two objectives. To find out the best economic rotation of various farm grown tree species in Kot Addu. To determine the level of profitability of farmers/ tree growers in Kot Addu. VIREVIEW OF THE LITERATURE Farm forestry has numerous benefits so farmers raise various woody plants along with agricultural crops for obtaining shelter for animals, fire wood and timber. Trees also beneficial as bio remedial measures for the control of pollution and erosion (Zubair and Garforth, 2005). Farmers prefer Acacia nilotica because it is a fast growing species and easily propagated. Similarly, Dalbergia sissoo and Albizia lebbeck are very important for production of fuel wood and timber. Naturally grown trees make haphazard landscape in farms but genius farmers adjust the tree plants on suitable place like boundaries of fields. In addition, Acacia nilotica render the economic benefits at the age of 10-15 years to the farmers. Timber merchants confer in order to reach an agreement with the farmer regarding to the price of fuel wood and timber wood. Nouman et al., 2006) reported that Daphar irrigated plantations were running in the profit with a benefit cost ratio of 1.29. High mortality rate of tree plants lead to less income in first 10 years. But next twenty years lead to greater income due to greater number of tree plants. In the study, the rotation of Dalbergia sissoo was 20 year (Azharet al., 2011). In 3 Tehsils of District Faisalabad viz; Samundari, Jaranwala, Faisalabad linear and compact plantations of Eucalyptus camaldulensis were evaluated. Economic benefits of those 3 plantations were considered. For Eucalyptus camaldulensis linear and block plantations of Short rotations (5-6 years) were most profitable (Majid, 1995). Friday et al., 2000) determined the net present worth of 50 acres teak (Tectonagrandis) plantation. He determined that 35 years rotation was more profitable than 40 or more years rotation. Posavec et al., 2004) determined the best economic rotation in Croatia for even aged tree stand. The net present value of 20 years and 150 years of trees was calculated. He stated that 20-130 years stand was continuously increasing because the mean annual increment for the stand was increased. But the net value for the age of 130-150 decreased because of decrease in mean annual increment of the stand for the same period. Tanvir et al., 2002) stated that in different zones of Central Punjab Eucalyptus camaldulensis gained maximum volume /mean annual increment in 8th year of its growth. Although Maximum increase in volume was in 7th year. But the worth of tree don’t rise in the ratio to the volume/year. Although the price per tree gradually increased with increase in volume per year but price per cubic foot decreased continuously after 8th year .Therefore, his suggestion is to harvest the tree plants during early age (within 7 year) in order to get maximum income. Economic evaluation of Eucalyptus camaldulensis plantation was carried out. It was determined that the plantations established for the betterment of soil provide more socio economic and environmental values at the age of 11 years. If the plantation is harvested after the economic age then it will surly lead the farmers to economic loss. On the other hand, Eucalyptus camaldulensis plantation grown for the purpose of pulp wood production achieved the maximum growth at 5-8 years of age. At this age, there is maximum net present worth and mean annual increment of the plantation. After this economic age, there is a decrease in mean annual increment, so, the owner of the plantation is directed to the economic loss (Niskanen, 1997). Chaudhry et al., 2003) determined the comparative growth of Poplar under pure stand and agroforestry system. He reported that rotation of Poplar in intercropping agroforestry system was more economic at 4th and 6th years of age as compared to the pure Populus deltoids stand. It was further reported that 8 year rotation age of Poplar was uneconomical for both systems of plantations.

Disc Brake System: How Does It Work Essay

Brake system is a device that creates frictions to slow down and eventually to stop the movement of an object. There are a few different types of brakes; however, they are all built on the same principle of friction. In automotive, the most common type of brake today is the disc brake because it provides higher efficiency and more safety to users. Disc brake consists of brake fluid, a piston, a caliper, brake pads, a rotor, and a hub. The following is a basic description of a disc brake’s mechanism. 1.When the brake pedal is pressed, the brake fluid is forced to enter the caliper cylinder where the piston is sitting in. In turn, that fluid pushes the piston, which is attached with a brake pad on the other end, toward the rotor. 2.Once the brake pad is in contact with the rotor, the caliper contracts to bring the other brake pad to contact with the other side of the rotor as well. The pushing of both brake pads against the rotor generates a friction force that will slow the rotation of the rotor and eventually bring it to a stop. 3. Because the wheel attaches to the hub and the hub attaches to the rotor, thus, when the rotor is slowed down, the wheel is also slowed down. 4.Meanwhile, the friction between the tire and the surface of the road also acts to slow the rotation of the wheel. Disc brake can generate a significant amount of friction. This is why its main applications usually involve movement with great velocity such as cars and aircraft. Because disc brake does require more maintenance than other simpler brake and because brake is directly related to your safety when driving, it is recommended to have your brakes checked regularly by a licensed brake technician/specialist.

Criminal Behavior And The Lack Of Education - 1367 Words

Criminal behavior is something that affects everyone, even if you don’t particularly engage in the act itself. Every time a crime is committed, we often find ourselves wondering what led that person to do that crime. We wonder why they did it because it is something that we could never do, so therefor we cannot fathom the act of engaging in criminal activity. Some people feel that people only engage in it just because they lack the thing that they try to steal or because of their specific background and race. In actuality, there is a link between criminal behavior and the lack of education. However there is also a link between the attainment of education and criminal behavior. There are several ways that theories suggest the affect that education can have on decisions that a criminal may make beforehand. According to chapter seven (Conformity, Deviance, and Crime) of the textbook Introduction to Sociology, functionalist theories along with Emile Durkheim and his concept of a n anomie, which is a situation where social norms loose their hold over individual behavior gives us insight into the struggle between education and criminal behavior. â€Å"Functionalist theories see crime and deviance resulting from structural tensions and a lack of moral regulation.† (Page 172) Students dropping out of school and coming from difficult backgrounds is seen as a norm within society.
