The Green Revolution
Technologyhas played a significant role in global transformation. Presently,almost every sector has adopted some form of technology to ease itsoperations. The agricultural sector is one of them. Technology hasbeen used to improve crop production hence the origin of the term“Green Revolution.” This concept has contributed to the increasein production of different varieties of crops such as rice and wheat(Giri and Tyagi, 2016). This paper, therefore, aims to outline theimportance of genomics and genetic engineering in improving foodproduction in addition to elaborating more on the ecologicalimplications.
Thedeliberate modification of the genetic material of plants or animalsis referred to as genetic engineering. Biotechnology as a whole hasplayed a significant role in ensuring that the world is food secure.Crops have been manipulated to make sure that they grow rapidly henceshortening the period between planting and harvesting (Goron andRaizada, 2015). Furthermore, these modified breeds are resistant todisease and can withstand adverse weather conditions. They are alsounlikely to be attacked by pests. These crops are commonly referredto as the high yield varieties and have led to greater harvests. Allthese benefits ultimately result in the availability of food for theentire humanity.
TheGreen Revolution has been criticized for numerous reasons. First, thetechniques contribute to the pollution of groundwater. This mayresult from the application of fertilizers and pesticides which havea higher probability of getting into the groundwater (Pingali, 2012).This might also lead to adverse health effects in humans who use thesame water for domestic purposes. Additionally, the improperirrigation system may lead to flooding or drainage problems on thefarms. For example, the high-yield varieties of rice and wheatrequire constant irrigation. This leads to the possibility of overirrigation. This has altered the chemistry of the soil. As a result,the soils are increasingly becoming alkaline or saline. GreenRevolution has also been criticized for the adverse reduction ofgroundwater table, and the emergent of pesticide-resistant pests.
However,some mechanisms have been established to which the negativerepercussions of the Green Revolution can be mitigated. Theapplication of chemicals has been reduced through the introduction ofgenes that are resistant to pesticides and diseases. This has reducedthe chances of chemicals penetrating into the groundwater hence thefood produced is fit for consumption (Datkar and Pethe, 2016).Therefore, human health is not compromised.
Finally,to meet the complex challenges of food insecurity, there is a need toembrace innovative concepts in agriculture through relying onscientific and technological breakthroughs. Furthermore, it is vitalto ensure that the small-scale farmers also benefit from theseinnovations in addition to encouraging the sustainable use of naturalresources.
