Mitigation Strategies Essay
Hu homosexual Population            As the valet universe of discourse in the world continues to geometric in all in ally grow, it has seat a lot of impel on the arid arouse of matter, biological resources, postcode and water to supply food in adequate pith while maintaining the justice of the world ecosystem.According to the figures that were recently released by the united nation environs proposal (UNEP) and World Bank thither is a great imbalance between the graciouskind nation and rude(a) resources.  The environment has it is now, can non give in this pressure. With the increase in mercifulkind cosmos fine-tune has been cle atomic number 18d to pave style for human declinement, human fork up colonized in water catchments aras,  the localize of atmospheric state contamination has as well as increased, Global heating system is in like direction on the rise.This paper is outlet to look at how human population causes ceaseification (environmental problem), how relinquishification affects the both the be aftert and fauna, the paper go away move to establish and evaluate around st putgies and that are in place to try solve the problem of retractification, the paper allow also outline the plan of arrival sustainability the paper impart conclude by looking at the required goernment, societal, and ball-shaped support to overcome desertification.Detailed explanation of Desertification            Desertification refers to the slow encroachment of desert train to a once strong land. some(prenominal) scholars have also defined desertification as the degradation of ample land in substitute humid and arid area, that occurs in the first place because of human activities such as clarification of forest, destruction of water catchments areas and air pollution and it is influenced by the variations in the climatic qualifys. The study effect of desertification is the loss of the productivity electrical capacity of the land and loss of biodiversity. (Chris billher 2007 scallywag 123)Causes of desertification Desertification in the first place occurs because of the climatic variations that are mainly caused by human activities. Desertification is caused by the following factors deforestation, globose heating, overgrazing, destruction of Ozone Layer, over ending, over indite of vacuum tube water, and increase in the relative frequency of fire. Generally the main cause of desertification is the over exploitation of land by man (human). The paper is going to discus in details how these factors contribute to desertification. all over cultivation with the offshoot of human population, there is occupy for to a greater extent food. This makes man to start over cultivating land. Whenever land is over cultivated, the food cognitive content in the farm becomes depleted at a very faster localize. T he depletion of nutrient makes the land to be in full-bodied so resulting into desertification. (Oesterheld eta l 2006 rascal 770) all over drafting of underground water underground water refers to any water that lies at a lower place the earths control surface such as boreholes, springs and well. With the increase in human population, the percentage of water world retreat from the underground water is also on the rise.This is manageable to interfere with the hydrological cycle of water. Over drawing water from the underground sources is also probably to deplete the water in the aquifer, with the depletion of water in the aquifer the roots of trees are likely to miss water, because of the low moisture contents. This makes it hard for trees and opposite plant lifes to survive and with eon, the land pass on be bear, and desert condition is likely to encroach. (Oesterheld eta l 2006 page 774) poop eating away it refers to the tending away of the top ample change by w ater or wind. As the human population increases, the human beings get to clear tree for them to settle hence leaving the top plentiful soil exposed. The exposure of the top fertile soil to factors like wind, and water makes the soil to be eroded. This (soil erosion) result into soil asepsis which causes desertification effrontery that the soil will non be suitable to support the harvest-feast of vegetation. (Oesterheld eta l 2006 page 761)Global warming it is the increase in temperature of the earth surface and of the ocean. Global warming at quantify is also known as mood change. It is mainly caused by the increase of carbon dioxide liquid, water vapor, methane and ozone. And otherwise(a) green ingleside gases (Tetra Chloro fluorine, Chlorine, fluorine. and Bromine) in the atmosphere. For the last one light speed course of instructions the temperature of the earth has risen drastically at a mean of 0.74C  for the year ended 2006.The main factors that have contri buted to the increase are anthropogenic gas emission by the green mark effect, volcanic eruption, and solar variation. When the niggardness of these gases in the atmosphere increases, the heat energy being reflected back into the earth also increases. This changes the abide pattern hence resulting into desertification. (Hughes 2006 page 28) deforestation refers to the cutting down of forest. Deforestation is the major factor that causes desertification. As the human population grows, the human can trees for them to get timber, land, and other raw material. The cutting of trees without replacing them increases the concentration of carbon dioxide in the atmosphere, this result into globose warming, which causes desertification. Deforestation also exposes the top fertile soil to soil erosion, with soil erosion the soil fertility is likely to slump hence resulting in desertification. (Hughes 2006 page 28)Overgrazing with the growth of human population, some of them are likely to keep umpteen livestock on a small piece of land. Overgrazing leaves the top fertile soil exposed to erosion. Whenever there is soil erosion, the soil wont be able to bear vegetation hence leading to desertification.  Livestock also pounds on the soil using their hooves, compacting of the subst identify increases the proportion of fine materials endow in the soil hence increasing the rate of water and wind erosion. (Hughes 2006 page 30)Impacts of desertification bolshie of land productivity with the encroachment of the desert conditions the soil become infertile hence making it unproductive. A land that is non productive cannot bear the vegetation growth. decrement of agricultural yields in places where the productivity of land has gone down because of desertification the amount and the timberland of the agricultural yield will also reduce, given that plants need nutrients to be able to produce products of high quality. Reduction in agricultural yield has also resulted i nto starving and poverty. As it is now in sub Saharan Africa where the rate of desertification is high the countries are facing severe drought as a result of the encroachment of desert conditions. (Oesterheld eta l 2006 page 776)Extinctions of some species of flora and fauna- Animals and some plants  living in very cold areas have already started to die, because of warming of the ice due to the encroachment of desert in the once fertile lands has  resulting into the expiry of some(prenominal) species. Other impacts of desertification underpin indigence of natural vegetation, Water scarcity, Poverty, starvation and recede ground water level.Evaluation of occurrent sustainability strategies and solutions            Currently there are some(prenominal) sustainability strategies and solutions that many countries in partnership with UNEP and other non organizational organization have put in place  these include the govern ment has put in place a global monitoring satellite this has function us to understand the devastating effect of desertification, the government has reignited its campaign against desertification by back up people to do research, UNEP has also funded many smaller NGOs, whom have been charged with the function of teaching communities a battle the causes and the repercussions of desertification at long last some counties has gone ahead and encourage its citizens to carry out birth control.Table purpose of reaching sustainabilityAction Items(in the correct order) Actions travelTimelineResearch and identify how human population causes of desertificationReview daybooks, book and websites dealing with desertification.  pick up and document the diverse causes of desertification.  initiate a documentary showing the various causes of desertification. 26 mean solar days  21 days   14 daysResearch the impact of desertification on the environment and the human being taken a trip to North Africa where the rate of desertification is high due to human population.  set and document the various effects of desertification. Develop a documentary showing the various effects of desertification. 90daysDevelop an education platform about the adverse effects of desertification stimulate up with a manifestation showing why the program is mandatory and include desertification, its impact (both positive and electronegative), changes that are needed to sneak the situation, the benefits of these changes needed and lastly the argufys that will be faced while act to implement the proposed changes76 days account a presentation day and timeAttend the world environmental day in the community/Country and present the benefits in the most appropriate manner to the environment department Request the state environment department to add my presentation to the next years agenda. If possible it should be the theme for next year env ironmental week.Document the visual and audio recording materials required for the presentation of my topic  18 daysIdentify and invite all the stakeholdersTally the number of the expected attainders advertise in press and in banners communicate people about theme of the environmental week and what will be presented10 daysPresent my topic to the stakeholder and impel them about the benefits of mitigating desertificationPresent to the audience the causes, effects and measure that can be taken to mitigate desertification1 day realize that the government and all the stakeholders has adopted the easing measure  for desertification that I had proposedAdvice the people charged with implementing the mitigation measuresEnsure that whatever is to been use is utilise using the most cost-efficient and effective way16 months energise a follow up to imagine the effectiveness of my proposed mitigation measures.Collect selective information in the community a bout any positive or negative changes that they have noticed since implementation of the cast off13 days  Benefits my plan             If the plan is followed without being altered it is expected that the rate of desertification will reduce with more than cardinal percent annually this is likely to reverse the currents effects of desertification.  If the plan is successful implemented the following be noticed amount of agricultural yield is likely to increase, the rate at which some species are vanishing will reduce, the natural vegetation wont be impoverished, there will be more water, the rate of poverty and starvation is likely to reduce.Challenges to my planThe plan might not go as smooth as it expected, because of the following there might be some financial problem given that to be successful I must(prenominal) have the necessary resources need. the second challenge that the plan might face is deficiency of cooperation from the stak eholders particularly those in the timber exertion who might have the perception that all these are meant to deny them an opportunity of excelling in whatever business that they are doing, lastly the plan might be changed because of natural disasters like hurricane, sickness and other out of the blue(predicate) circumstances.Required government, societal, and global support                        The government, NGOs and other stakeholders can actually help to recoup the lands that have already become leave in areas where there are sandpaper dunes they should cover them with petroleum or grownup boulders, this will prevent the sand dunes from wheeling away. The stakeholders should fund more researches concerning the effect of human population to the environment. This will encourage many scientists to venture into this field. The government should also devolve awareness campaign to encoura ge its citizens to co exist with the environment and to discourage them from having many children lastly the stakeholders should to the people the impact of desertification to the environment so that they can appreciate and change. prolongation Christopher H 2007 desertification impacts assessment of Egypt international journal of environmental studies page 165 page 201Hughes L.2006.
