Effects of Global Warming on Agriculture

Global climate change is a duplex coin; the first discussion of the recent movie "The day after tomorrow" may be the best overheating, and we are all doomed. Another discussion has never been made into a movie, but we can survive in quite comfortable circumstances by changing our lifestyle a little. The scientific community seldom denies the existence of global climate change, but the argument is whether it poses a threat. Therefore, the very important aspect is the impact on agriculture.

There are three main effects of global warming. The first global warming affected agriculture, that is, gas emissions trigger climate change in the agricultural sector. In addition, Karki (2008) noted agriculture includes greenhouse gases with practices, irrigation and herbicides, pesticides and other chemicals. In addition, the impact of the environment on agriculture is especially soil drainage, soil erosion, so crops reduce production. In addition, the agricultural process leads to the emission of greenhouse gases, for example, carbon dioxide emissions related to deforestation, rice planting and livestock fermentation release methane and fertilizer use releases nitrous oxide. Finally, Karki (2008) pointed out that there is a possibility that the sea level may rise by 1 meter by the year 2100 and sea level rise has serious consequences for special areas, such as East Asia, erosion, floods I will give it.

Global warming and agriculture are interrelated worldwide. Global warming is caused by changes in average temperature, rainfall, extreme weather (such as storms and heat waves), changes in pests and diseases, changes in atmospheric carbon dioxide and terrestrial ozone concentration, changes in nutritive value of specific foods , It affects agriculture by sea level change. Global warming has an impact on agriculture, and its impact is ubiquitous all over the world. Future climate change may adversely affect crop production in low-latitude countries, but the impact on latitude in the Northern Hemisphere may be positive or negative. Global warming may increase the risk of food insecurity for some vulnerable groups such as the poor.
