本篇代写essay-有机农业讲了在世界上一些面临着与饥饿有关的问题的贫穷国家，有机作物的产量与传统作物没有什么不同。佩蒂和蕾切尔在发展中国家开展了200多个不同的农业项目，研究表明，这些项目的增产幅度约为93% (Doltra and Olesen, 2013)。在印度中部的农场，经过大约1000名农民的种植，发现棉花、小麦、辣椒和大豆的产量比正常农场高出20%。在肯尼亚进行的另一项研究表明，与一些非有机农民相比，玉米有机产量的生长场地较低。本篇代写essay文章由加拿大第一论文 Assignment First辅导网整理，供大家参考阅读。
It has also been observed that in some of the poor nations of the world which are facing the problems related to hunger, there is no different between the yield of organic crops and conventional crops. According to research conducted by Petty and Rachel over 200 different agricultural projects in the developing nations, it was stated that the projects revealed which there was an increase of around 93 percent of the yield (Doltra and Olesen, 2013). In the farms of Central India, it was found after the cultivation of around 1000 farmers that the yield of cotton, wheat, chili and soy were as higher as 20 percent in comparison to the normal farms. Another study conducted in Kenya stated that the field for the growth of the organic yield of maize is lower in comparison to some of the non-organic farmers.
Organic farming in sustainable food systems
From the year 1999, there is a huge expansion of organic farms in the different parts of the world. There has been a growth of organic farmers to around 37 million hectares. The regions that have the largest organic agricultural includes Oceania which includes Australia, New Zealand and the Pacific Islands. In addition to this, the other regions include Europe and Latin America.
At present, the organic farming can be established as per the international standards and at present around 84 nations in the world have been implementing the organic farming. According to the federation of Organic Agriculture, the organic farming is a production system which has been highly dependent on the ecological processes including the recycling of the wastes instead of the use of synthetic materials.
In a large number of circumstances, organic farming can produce crops in good yield. The conventional practices in agriculture generally degrade the soil quality, but organic farming will make it more and more better. Therefore, it can be stated that the organic farming can easily contribute to the sustainable food systems because of improvement done in the nutritional intake and sustainable livelihood in the rural areas. In addition to this, it helps in the reduction of vulnerability of the climatic changes and enhancement of the biodiversity. The sustainable practices which are associated with the organic farming are very much labor incentive (Oliveira et al., 2013). Another sustainable benefit of the same is that it consumes 50 percent lesser amount of fossil fuel energy in comparison to the conventional farming. Moreover, the common practices which are being used in the organic farming such as the use of the rotating crops, application of the mulch for the purpose of emptying the fields leading to the reduction in the vulnerability of the harsh patterns of weather also helps in the increase in sustainable practices. It has also been found that the organic farms in general have a bio diversity, which is 30 percent higher in comparison to normal farms. This includes birds, insects and plants in large numbers.
The sustainable farming practices through organic farming have been largely increased in the western nations. An example of the same is Europe where organic farms include by 9 percent to around 10 million hectares, which is the largest growth in a single year in any region. In the year 2011, there was an increase by 9.5 per cent in the organic farms in USA.
In the coming times, sustainable food systems which are done through the organic farming will become more and more important. This is because there will be a growth of organic farms and the overall population.
Also, organic farming helps in the conservation of the number of resources. The organic farmers generally protect the soil of the farms from being eroded. This is because of the process involving the plantation of the cover crops, mulching, intercropping and the implementation of the methods such as aero-forestry (Garnett et al., 2013). These methods are useful as it helps in the increase in the overall organic content of the soil, which also has a positive impact over its capacity to hold the water. In addition to this, the covers of the vegetation also have a positive impact on the water holding capacity of the soil and the conservation of the humidity by protection of the soil from the direct sunlight. Therefore, it can be stated that organic agriculture can lead to the sustainable development of the food systems. This is because of the fact that the organic farming helps in the effective use of the organic principles.
