Abstract
The article by Lobell and his associates focuses on the investments that are made to ensure food security due to the threat of global warming. Moreover, the projections about the climate of the world in 2030 are taken into consideration. The needed adaptations are discussed in the course of the writing to shed light on the importance of taking action with utmost immediacy.
The article by Schmidhuber and Tubiello goes on to delve deep into the four main factors (availability, stability, utilization, and access) that are associated with food security. There is a qualitative discussion of the negative impact of food security of human population. The article further opens up avenues for a new perspective toward combating global warming and threat to food security.
The article by Parrya and associates focuses on the patterns of global warming and its impending effect on food security. Thus, this writing makes a prediction of the possible impact of global warming in the future and provides a holistic understanding of the threat to human lives in the future. The writing provides probable figures of human population that would be threatened by lack of food by 2080s.
The article by El-Sharkawy specifically focuses on the disparity in effect in the various regions of the world when it comes to global warming. The author delves into the intricacies of the effect on human lives. The writing focuses on the factors for the tropical or subtropical region of the world. It discusses how the other regions are affected with negative effect on the food system and life of people.
The article by Gregory, Ingram and Brklacich delves into the various ways in which the climate change can come to influence the agricultural produce in a region. Thus it goes on to provide a clear insight into the ill-effects of global warming on the human population. The many the multiple socio-economic and bio-physical factors that come to affect food security are discussed in detail.
The article by Wheeler and Braun delves into the ill effects on climate change on food security. The article discusses how the growth of crops would get affected with rise in temperature. This would lead to lack of food in the world. The authors further discuss the need of investment in mitigation actions and adaptation toward a climate-smart food system thinking about the future of mankind.
Dwivedi and others, on the other hand, focus on the impact of pests on the crops. The authors delve into the interrelationship between global warming and rise of pests thereby threatening the food security of the people of the world. There is explication of the Mycotoxin biosynthesis gene-specific microarray in relation to the issue at hand so as to provide the readers with an in-depth knowledge of the matter.
Global warming is one of the most significant issues in the entire world today with the ill-effects getting catapulted with every passing day. Global warming is an irreversible process and it is leading to a sea of change in the world society that is leading to immense impediments to the people of the world. In the past 50-70 years’ time, the surface temperature of the entire world has been found to rise by 0.8 degree centigrade. There are a number of reasons that have led to this change in temperature that include the catapulted rise of biogenic gases in the world atmosphere that creates the ‘green-house effect’ in unison with the water vapor in the atmosphere. It needs to be reckoned that most of the greenhouse gas emissions are caused by human activities in the world. The key reasons of global warming like too much utilization of fossil fuel, poor land management leading to deforestation, degradation of soil due to incessant cultivation have an enormous effect on the world population as well. Thus, it needs to be understood that global warming is intertwined with major social issues like food security, malnutrition and hunger in this world.
Now, there can be no denial that the society and economy of the world are getting affected by the continuous process of global warming. With time, the entire world is bound to witness major changes in the agricultural ecosystems. Surely, the tropical as well as the subtropical regions of the globe would also be affected by global warming. These areas would be affected the most with the people suffering the brunt of the nature. Slowly, the social and economic spheres would get affected by the climate change. The natural resources of the affected regions can be expected to be on the wane due to the climate change. (Schmidhuber et. al, 2007) Lower crop yields in such major parts of the world would affect the lives of people in a negative manner. Lack of food would lead to problems for sustenance that would gradually get spread to other spheres of life. There can be no denial of the fact that things like food security, well-being of the population and agricultural production are liked with one another while all of this is dependent on the climate since agriculture is totally based on it. No artificial way of irrigation would help combatting global warming. (Lobell et. al., 2008) While the major cause of global warming remains the lifestyle and lack of awareness among the vast population of the world, it is the human society of the world that has to face the impending disasters that would loom over the entire society after a period of time.
Once again, it has to be remembered that the effects on the human society are very far-reaching in nature. The tropical and subtropical region that is prone to facing the gravest problems due to global warming consists of a huge population. If the crops are not grown in optimum amount in this region of the world, the population would suffer. Firstly, many people are involved in the field of agriculture that they take as their mode of earning. Also, the crops that are grown in the region provide for the food supply that satiates the basic need of food security of innumerable people living there. As the agricultural production would wane with time, many people would suffer economically. They would be left in a state of impediment with regard to their monetary conditions while the situation would only be worsened by the lack of food. The people living in the region would not get the needed good items that they used to get before. This would complicate the inter-national dynamics as well as the food supply chain. The countries affected by lack of food would require importing food grains on a regular basis, although that cannot be a viable option. (El-Sharkawy, 2014)
The impending thing would be migration as a large number of people would seek other places to move out in search of better prospects of living. Thus, the population density and distribution of the regions and the world as a whole would get affected a lot. This would eventually lead to major socio-economic problems for one and all. The people would find it hard to find houses, jobs, and other basic necessities if the population density of a region suddenly gets increased without proper planning and development of the area. Apart from this the huge migrated population might also lead to trigger an ecological imbalance as building dwelling places might lead to further deforestation. Thus, migration cannot be a viable solution to the issue at hand. (Parrya et. al, 1999) More population concentrated at one region would lead to enhanced environmental exploitation by the population leading to further complications. The holistic situation would be of lack of food security, malnutrition and hunger among the people of the world. The need of the hour is to analyze the possible threats and find viable solutions to the problem of global warming so that a better future for the entire human society can be ensured.
Global warming would also lead to the massive increase in the number of pests that can be a potential threat to the crops that are grown for human sustenance. As such, under the changed circumstances of the world climate, the human society can also be challenged by possible pest epidemics. This would further complicate the situation as the problem of lack of food would make things very challenging for the people of the world. Apart from this, the climate change can cause contamination of mycotoxin producing fungi in the food items that are supposed to be consumed by the humans. Thus, one can only imagine the famine-like situation and the impending hunger that would cause havoc in the entire world. It has to be noted that the enhanced use of agro-biodiversity is very important in the society for coping with the negative impacts of the phenomenon of global warming. The condition at present and the future would truly lead to testing times for the world population for sure. There can be no denial of the fact that the humans have to come up with technological innovations that would encompass climate-resilient crop cultivars for the purpose of producing food for the 9 billion odd people living in the world. (Dwivedi et. al., 2013)
Millions of people in the world are malnourished or undernourished in the present times. While the countries are unable to provide proper nourishment to the population in the present day scenario, further degradation of the climatic factor would lead to major problems. For example, there would be more natural disasters that would harm the population. Now, all of this would have a negative impact on the possibility of ascertaining food security to the people of the world. Crops can be destroyed during such natural disasters leading to lack of food for the people. Hence, the issue of global warming has to noted and acted against with immediacy and prime importance by one and all. (Gregory et. al, 2005) Also, with time, global warming would lead to the rise in sea-level all over the world. This would come to affect the lives of people residing in the coastal regions of the world and the deltas. Moreover, the glacial melting would get accelerated by global warming leading to alteration in the availability of water on the lands. There would be gradual degradation of the ecosystem leading to an extinction of the human race in the course of history.
All the countries of the world have to be united to fight for the cause of food security. Raising the awareness about global warming or climatic change is a major step toward ensuring food security. Many world leaders have already tried to make people understand the importance of the matter. However, more efforts have to be there for the purpose. It has to be noted that the mass media must be very active in the dissemination of the information regarding global warming. Every person should be committed to minimize carbon footprint and other lavishness that add to the global warming. People must be very careful about lifestyles. The world must have a viable plan for combatting the threats to food security. There has to be scientific discovery in the domain of artificial food items to balance out the lack of naturally grown food materials. (Wheeler & von Braun, 2013) It would be a grave mistake on the part of any individual to see global warming distinctively sans any relation with the socio-economic issues that have become the problems for the entire world in the present times. Rather, a proper comprehension of the intertwined nature of global-warming and food security, malnutrition or hunger would enable one to understand how everyone needs to take the stride forward to pave a better future for the world population in the future.
In conclusion, it would be apt to say that the world is an abode for many living species. Humans have no right to exploit the resources of the world and create a milieu of uncertainty of sustenance for themselves as well as the other living species in the world. As an intelligent and advanced species residing on the earth, humans have to take the responsibility of making this globe a better place to live in. Ignorance about the environmental issues that are haunting the world would only cause accentuated socio-economic issues that would come to affect the lives of innumerable humans directly and vehemently. Global warming is a massive threat to every living individual in this world and it has to be controlled in the best possible way. A better world would ensure a better future for one and all living on earth.
