In today’s world the technology is advancing, and with the increase in technological advancement issues like climate change and global warming have surfaced. One of the main issues of climate change is the impact on agriculture. The average agricultural output of countries has decreased leading to chronic hunger situation across the globe.
Increase in Temperature:
1. As pollution is increasing the amount of carbon dioxide in the atmosphere is increasing and this is resulting in increased temperature which leads to climate change which in result has disrupted seasonal weather changes. The change affects the agriculture adversely like when the summer season remains for a longer period of time, the insects affecting the summer crop starts growing their population as their breeding time increases which in result effects the crop yield. A rise in these insects or pests makes the farmers invest more money on the pesticides and fertilizers which directly effects the quality of soil and production of quality crops.
2. Increase in Temperature can result in drought and dried soil thus, making difficult to grow crops especially water-intensive crops and as we know in some parts of the world scarcity of water is a huge problem than continuing agriculture and land irrigation is close to impossible at such places.
3. Increase in temperature can lower the nutritional value of the crops as when the level of carbon dioxide increases then the concentration of protein in crops decreases like these days happening for soybean crops. Also, the rise in the amount of carbon dioxide reduces essential minerals in many of the crops such as rice, wheat, etc.
Mostly, climate change has fewer effects on global agriculture, but these effects are unevenly distributed geographically. Most of the losses are suffered by less economical countries such as those countries of South Asia and Africa. These countries are less economical thus they are unable to adapt these climatic changes. According to estimates of the Food and Agriculture Organization, there are 795 million undernourished people worldwide. This shows in the decrease of nearly 200 million over the previous 20 years. The most vulnerable to climate change is South Asia and in South Asia, about 75% of people are poor and dependent on agriculture.
As per The Peterson Institute, agricultural production in developing countries will fall between 10% to 25% and due to global warming, it will decrease the agricultural productivity of India further by 40% if timely action is not taken.
UN researchers predicted that higher temperature in higher latitude will help in high productivity and Canada and Russia are winners in this productivity contest and tropical regions are going to face less productivity in agriculture even South Asia and Sub-Saharan Africa will also be less productive in agriculture.
Climate Change is affecting agriculture in various ways globally and if this continues then it will continue to impact global agriculture and will lead to global starvation.
Technological advancement is good for the development but if the technological advancement is questioning the existence of mankind then how can we call this technological advancement a part of development. What we should be looking for is Sustainable Development. It is most important to first concentrate on our environment and we should concentrate most of our mind on researches on how to save our environment and how to save our nature then, the nature will save us otherwise the natural phenomenon will be continued and our existence will be destroyed. “if there is nothing to eat, then what need of plates, utensils etc. is”.
Thus, we should research on the ways of saving nature as we can only live if there is nature. We should work something for a greater good like there are several organizations working day and night for a cause not only to generate a plan of action but also to implement those plans to save the environmental degradation.
