A literature review of the applications in reducing green house gas in the agricultural system - Essay Example Industrial agriculture causes global warming because it is intensive in fossil fuel, operations from confined animal feeds lead to emission of methane, application of nitrogenous fertilizer causes emission of nitrous oxide, and finally, large scales of land within the tropics are being converted into intensive monoculture plantations. The large livestock populations in the world produce high amounts of greenhouse gases that consequently influence climate change. Changes in the soils’ carbon flux can be very significant, even though it is small, because of the volume of soil (Smil, 1999, P127). Despite favor of livestock production by market forces, Smil (1999, p. 130) examines that application of alternative methods may help in the reduction of greenhouse gas emissions while providing good livestock returns, sustainability and health where deforestation, land degradation, and feed-crop dependence are avoided. Mitigation efforts in agricultural systems include keeping fewer livestock, conservation tillage, intensification of livestock without crowded confinement, and organic farming (Casey and Holden, 2006). Reduction of feed grains that are chemically fertilized is however the most effective way of reducing pollution by greenhouse gases (Casey and Holden, 2006, p. 234). Maize, wheat, and soybean production emits about 17 million tones of carbon dioxide per year (IPCC, 2007, P.241). Together with the fast increasing number of livestock, the possibility of changing the balance between sequestering nitrogen and nitrous emissions in the soil is big. \ Another important strategy of reducing greenhouse gases by agricultural system is the application of policy mechanisms stipulated by Kyoto Protocol’s mechanisms of clean development to provide support and stimulus small scale farmers who are willing to practice sustainable agriculture. Potentially, about 1 tonne of carbon is

What is the 'risk' of thinking the security of liberal governance as Essay

What is the 'risk' of thinking the security of liberal governance as risk management - Essay Example s the most critical aspect of the governance and politics has its roots in the era emerging as an aftermath of the cold war which witnessed the collision of two super powers with each other and resulting split up of the one. What is however, critical to note that after the cold war era, the overall focus from assessing the dangers to the security to the overall risks that may be arising out of the changing situation? This transition from threat based assessment to risk based assessment as well as assuming probabilities and their impact therefore requires a comprehensive understanding of the overall risk approach that has been adapted. This transition therefore needs to be understood in larger context of the political as well as from international relations point of view. The 9/11 Commission also blamed the various security agencies for their failure to anticipate and imagine the threats that were being present to the security of the US. Similar findings were also present into the report of the Commission that probed the London Bombings and stressed on the need for developing the ability of the government agencies to look into the unknown and perceive the various risks that may be arising.(Goede, 2008). This approach therefore requires that the modern societies must develop their abilities to pre-empt the risks and have the required resources and will to combat such risks in different manners. The events of the 9/11 and 7/7 therefore also indicates towards the need for adapting an approach that will allow the governments and societies to bring forth changes that can safeguard them against the potential risks. Traditional methods of countering with the security threats therefore may not suffice given the fact that the world at large has became really fragmented and the conflict of interests between nations is becoming more vivid and threatening. It is argued that with the passage of time, the overall nature and orientation of the concept of risk and security has
