Rehabilitation is the process of reclaiming land for economical or conservation purposes. This process usually involves re-vegetation. The main aim in rehabilitation is to either return the land to a self-sustaining ecosystem or prepare the land for human use, i.e. crops, pastures and plantations. Rehabilitation should take place at a rate that is significantly higher than natural succession.
Several principles are implemented for successful rehabilitation. Of these principles includes the need for preventing disasters and anticipating problems before they arise, if this is taken to consideration then rehabilitation will be less costly and trouble free. When rehabilitating a site, all the components making up the ecosystem need to be looked at individually. They include soil, climate, vegetation, time and animals. These components need to interact at certain rates in order for the desired effect to be achieved and so might need to be altered. There are other principles of rehabilitation, which will be discussed, in greater detail. There are many methods and strategies involved in rehabilitation which, are specific to a site. In this case, surface mine reclamation and farmland will be looked at. A step by step illustration of the processes involved will be covered. When rehabilitating mine land, it is important to first prepare a plan before mining takes place.
Researching and obtaining data on the floral and faunal elements of the ecosystem by conducting surveys of the upper, mid and under-story species present. If the aim is to restore the land to its original ecological balance and to conserve the species present, then further studies should be conducted on the ecology of the native species, i.e. seed biology of all species. Propagation techniques and the order of re-establishing species should be studied. When rehabilitation work was conducted on the bauxite mines in the southwest of W.A., special research was conducted on the germination requirements of sown seed.
The aim in this case was to re-establish a self-sustaining forest, which maintains water, timber and all the valued qualities of forest.
The timing component was carefully considered when removing topsoil in summer to ensure maximum seed store this was achieved when the forest was cleared after seed set took place. Hand seeding was done soon after ripping in order to ensured that the seeds other propagules were well established before germination.
When conducting mining operations it is generally desirable that rehabilitation work takes place at the same rate as mining occurs.
The soil component in this case needs to be removed in layers
(topsoil and overburden) and stock piled during the mining process. The topsoil is very important because is contains most of the seed, propagules and micro-organisms which are needed for
The Southern agriculture was reconfigured in the wake of the Reconstruction by sharecropping and the crop-lien system. Sharecropping was a system they used after the Civil War where a landlord allows african americans to work his land in exchange for some of the crop. Sharecroppers were to have half of what they grew if all the conditions were followed, but if they were not, then they would have two-fifths of what they grew. They were not able to work their own land if there was work to be done one their landlord’s land. The sharecropping system existed because the white plantation workers wanted to bring back a system like slavery, where african americans would work for them for very little pay. The cotton agriculture changed because
In the case at hand, Park Meadows argues they have new evidence sufficient to justify reconsideration of the partial grant of summary judgment for Dillard’s. Park Meadows also contends that, in light of this new evidence, reconsideration is warranted to prevent manifest injustice. The evidence Park Meadows claims is new and justifies reconsideration is an email exchange in March – May of 2013 between Park Meadows and Dillard’s store manager and an accompanying affidavit done March 15, 2018 regarding the planter boxes outside of Dillard’s. Park Meadows contends that the email was not previously available until Jeff Koch provided it to counsel after the order on February 20, 2018. Park Meadows further contends that they were not aware of the
Landscape fragmentation contributes to loss of migratory corridors, loss of connectivity and natural communities, which all lead to a loss of biodiversity for a region. Conservation of biodiversity must include all levels of diversity: genetic, species, community, and landscape (CNHP 1995). Each complex level is dependent upon and linked to the other levels. In addition, humans are linked to all levels of this hierarchy. A healthy natural and human environment go hand in hand (CNHP 1995). An important step in conservation planning, in order to guarantee both a healthy natural environment as well as a healthy human environment, is recognizing the most endangered elements.
Racism seems to be a growing problem in America, and it should be diminishing as our society progresses. Many acts of racism shown in The Power of One have reoccurred recently.
As the world population grows and consumption per person increases, the demand for food is rising. To an extent, fossil fuels have made an increase in food production achievable, but the finite supply is rapidly depleting. Over the last 50 years, global food production has tripled (Mosier et al. 2004). Despite this, an estimated 870 million people were undernourished in 2010-2012 (FAO 2013) while in 2008, 5...
Racism can take on many forms that plague the brain with irrationality that affects an individual’s thoughts and actions. Racism can be a physical form, through an external action, or can branch off into unethical thoughts. This is more known to be a discriminative thought, judging a person based on impressions. This social problem can also be ignored by the oblivious persons of the crowd. Many individuals speak out about how racial tension is long gone and forever forgotten ever since the first African-American was elected to be president in 2008, but this can be evidently proven false. Racial tension is still here to target the minorities in the forms of affirmative action and Ferguson conflicts.
Intelligence can be defined in many different ways since there are a variety of individual differences. Intelligence to me is the ability to reason and respond quickly yet accurately in all aspects of life, such as physically, emotionally, and mentally. Anyone can define intelligence because it is an open-ended word that has much room for interpretation. Thus my paper is an attempt to find the meaning of human intelligence. There are a couple of scientists who have tried to come up with theories of what makes a human being intelligent.
Each stage is very different according to Piaget. Cognitive theories focus the attention on conscious thoughts which means someone is more aware of their surroundings. Sensorimotor: Birth to two years. In this stage infants get the feel for the real world and are able to understand physically. Preoperational: two to seven years. Children during this stage are able to identify pictures and symbols. Concrete: Seven to eleven years. At this point children are very concrete in their development but also children start to develop logically and are more organized. Formal Stage: Twelve and up. Teens during this stage are able to think more into depth for a
In order for us to maintain our lives, we need to consume food to supply nutrient-needs for our bodies. As the global population increased, the demand for food also increased. Increased population led to mass production of foods. However, even with this mass production, in under-developed countries, people are still undernourished. On other hand, in developed and developing countries, people are overfed and suffering from obesity. In addition, the current methods of industrial farming destroy the environment. These problems raised a question to our global food system. Will it be able to sustain our increasing global population and the earth? With this question in my mind, I decided to investigate the sustainability of our current global food system.
Each of the stages performs on different principles, but “integrates and transforms the previous one as it comes into being” as the individual progresses to “adult intellectual functioning” (Feldman, 2004, p. 178). These stages are what were came to be known as Piaget’s Theory of Cognitive Development.
The cognitive development perspective focuses on how children construct knowledge and how their constructions change over time. Piaget believed that children naturally try to make sense of their world, by engaging, touching, sucking, listening, and looking. Piaget’s theory of cognitive development was inspired by observing his own kids, and how they interacted with their surroundings. Piaget describes four major stages of cognitive development. Each stage represents a change in children and how they learn and understand their environment around them. It begins at birth until about 2 years of age. It is based on sense and motor skills. And how well they physically interact with their surroundings. Motor skills can be defined as anything that requires an infant to use their muscles, such as
“The influence of Piaget’s ideas in developmental psychology has been enormous. He changed how people viewed the child’s world and their methods of studying children. He was an inspiration to many who came after and took up his ideas. Piaget's ideas have generated a huge amount of research which has increased our understanding of cognitive development.” (McLeod 2009). Piaget purposed that we move through stages of cognitive development. He noticed that children showed different characteristics throughout their childhood development. The four stages of development are The Sensorimotor stage, The Preoperational Stage, The Concrete operational stage and The Formal operational stage.
It used to be that fine dining establishments featured imported ingredients on the menu. These days, many chefs in high quality restaurants take pride in featuring locally grown, seasonal items. Even some large chain grocery stores now offer meat and produce from local farms. While most Americans probably would not feel the need to be as close to their meat as Makenna Goodman describes in “Ever Wonder if You Could Kill What You Eat? We Did the Other Night”, there is growing support for Goodman’s ideas that being closer to the food results in better food quality (246). Many Americans seem to concur, as they are now willing to pay more for locally grown and organically raised food. Having seen countless local farms plowed under to become housing developments or shopping malls, and having dealt with several epidemics of tainted food, Americans are more conscious of the ‘support your local farmer’ movement. If this new ‘food fashion’ continues to grow in popularity, it will help strengthen local farms that in past years have suffered at the expense of large commercial farming enterprises. According to Michael Pollan federal policy has promoted industrial agriculture, or agribusiness, since the Nixon era in the belief that keeping food costs low by obtaining maximum production of commodity crops (corn, soybeans, wheat, and rice) was in the best interest of the national political agenda (186). In “Farmer in Chief”, Pollan asks President Obama to change federal policy and instead promote local farming, asserting that how Americans grow, process, and eat food impacts the health care crisis, energy independence, and climate change (187). Goodman, Pollan, and others agree that more local, small-scale, farming will be better for th...
