The International English Language Testing System or IELTS is an English language proficiency test taken for study, migration, or work. The crop growing skyscrapers reading answers will help students prepare better for their IELTS examination. To ace the reading section, practice questions are necessary with varying levels of difficulty. The reading test has fourteen types of questions. This particular answer covers two types of questions, i.e. Sentence Completion and True-False-Not Given. This reading section passage will test you for vocabulary, grammar, and language.
There is a growing shift towards urbanization since reports state that 80% of the global population on Earth will reside in urban areas by 2050. Even if estimates are applied conservatively to present demographic data, the population of human beings on Earth will have gone up by another three billion citizens in this period. At least 109 hectares of fresh cultivable land will be necessary for feeding the growing population and this is 20% bigger than the size of a country such as Brazil for instance. At the same time, this assumption takes into account conventional methods of farming which are in vogue today.
Currently, worldwide, more than 80% of available land for cultivation or farming is being used. On a historical basis, approximately 15% of this tally has already been wasted due to poor supervision, management methods, and lack of awareness. What can then be a solution for feeding the entire global population? How will we ensure that people do not go hungry in the future?
Indoor farming is a concept that has had some traction earlier and is not completely new today, because hothouse produce has been practiced for several years, especially pertaining to tomatoes and other crops. The new aspect is the scalability of this type of technology for accommodating this new addition to the global population by 2050. Many experts are of the opinion that wholly unique perspectives are needed for indoor farming models, with technology serving as a bedrock for the same. Vertical farming is one such innovation that has been proposed in this context. The concept basically pertains to growing crops and produce at multi-storied structures and that too in conditions that are environmentally regulated. They will be located within major urban centers, while taking off the load on transportation systems needed for ensuring food for urban consumers. It goes without saying that these farms have to be more affordable and simple to build along with adhering to all necessary safety protocols at the same time. If this concept can be executed efficiently, then we can witness a scenario where diverse food crops can be sustainably produced and there would also be production taking place throughout the year instead of a few specific seasons. This will also contribute to repairing/regenerating global ecosystems that have gone waste due to prolonged horizontal farming methods.
Human beings needed around 10,000 years for harnessing the knowledge of growing food crops that are the major consumables today. At the same time, we also tragically laid waste to agricultural and fertile land, turning these oases of greenery and flourishing ecosystems into arid or semi-arid regions. We also shifted towards increasing urbanization and 60% of the global population prefers living in major cities at present and vertically at that. Hence, for the masses, human beings have their own ways to find shelter from the vagaries of the environment although our food-bearing crops/plants are vulnerable to the same. Human beings still hope for better weather and minimal damage to food crops every year.
With climate change becoming a major threat to life itself, this approach does not work smoothly anymore. The world is already witnessing severe hurricanes, cyclones, floods, belligerent monsoon periods, and droughts which are impacting the entire food chain, contributing to the elimination of millions of crops annually. Those who believe in the vertical farming concept state that this will bring several benefits alongside. Crop production will take place throughout the year, as mentioned since they will be grown in optimal and artificially-regulated environments.
At the same time and most importantly, these crops will not be at the mercy of the elements including floods and long periods of drought and even pests that routinely harm crops. All the food that is produced, will be grown in an organic manner, completely doing away with fertilizers, pesticides and herbicides alike. This will naturally eliminate many harmful diseases and fatal ailments from the world and basically the entire system of life at large.
The entire vertical farming process will necessitate higher energy consumption although the production of methane will ensure energy restoration to power grids and this is possible through composing parts that are not edible. It will considerably lower the usage of fossil fuels, eliminating the requirement for tractors and other equipment along with ploughs and even transportation/shipping at a large scale.
However, one of the disadvantages of the system is that the plants will be needing artificially-generated light for survival. If this is not uniformly ensured, then those plants which are located in proximity to open areas or windows will be receiving higher proportions of much-needed sunlight and achieve swifter growth in comparison to their peers, thereby bringing the overall effectiveness of the system into question. Greenhouses that are single-storied, automatically ensure natural light for plants in this context, although it is not possible to do away with artificial lighting entirely for many of them.
At the same time, consider the development of multi-storied buildings with zero natural lighting. This will need more costs and energy. However, the only solution lies in renewable and more affordable energy sources. Light generation may otherwise hinder the success of the concept.
Another new avatar of vertical farming is the method of using stacked trays for the growth of plants, which use rails for movement. This movement enables ample sunlight for plants periodically and the system is already being deployed in several regions of the world. This may function neatly in a single-storied facility like a greenhouse without the need for lighting overhead. However, the efficacy of the system is still being tested according to reports.
Vertical farming techniques may help eventually in catering to the growing food requirements of a rapidly increasing global population. However, the immediate scenario necessitates more actions for lowering the negative impacts on the environment that lead to disastrous consequences, especially regarding energy usage. It is quite possible that a majority of our food will be grown in these ways in the near future, although experts are pinning their hopes more on the utilization of space that is available on rooftops in urban zones.
Here are the questions that you should make a note of:
Question Numbers 1-7-
Complete the sentences below.
Choose NO MORE THAN TWO WORDS from the passage for every answer.
Question Numbers 8-13-
Do the following statements agree with the information given in the reading passage?
In boxes 8 - 13 on your answer sheet, write
TRUE if the statement agrees with the information
FALSE if the statement contradicts the information
NOT GIVEN if there is no information on this
8. The concept of indoor farming is not new to humans.
9. By 2050, nearly 80% of the human population will live in urban centers.
10. Vertical farming cannot be preserved by humans due to the usage of tractors, plows, etc.
11. Vertical farming won’t be affected by droughts, floods or pests.
12. By making use of the conservative estimates in the current demographic trends, the human population will increase up to two billion.
13. The major setback for vertical farming is it spreads non-communicable diseases.
Paragraph 2 of the passage mentions the indoor farming technique and the hothouse production of tomatoes, onions, and other vegetables, which has been trending for quite some time.
2. Artificial lighting
Paragraph 4 talks about a setback of the vertical farming method, i.e. the requirement of artificial lights for plants, unlike their regular counterparts.
3. Three Billion
In paragraph 2, there is mention of an urgent need to expand the technology for feeding three billion members of the population.
In the first paragraph, Australia is mentioned explicitly where it says that approximately 120 hectares of new land, which is 20% bigger than Australia, should be able to cultivate sufficient food for feeding people if conventional practices of farming continue in the same manner as they are implemented in the current scenario.
5. Methane gas
The third paragraph talks of how, while the system would need energy, it would replenish the same in another format to the grid through the generation of methane gas from the composting of non-edible plant parts.
6. Horizontal Farming
In the second paragraph, it is mentioned that vertical farms will be guaranteeing sustainable development, the production of a safe and varied food chain (round-the-year production of all crops), and urban renewal, along with the reconstruction of those ecosystems that were previously hampered by horizontal farming.
The second paragraph talks about multi-story buildings where the growth of crops takes place in environment-friendly circumstances. This also talks of how the concept, if implemented in urban areas, would lead to lower costs of transportation for food.
The indoor farming technique is not something new, as mentioned in the second paragraph, where it talks about the hothouse production of onions, tomatoes, and other vegetables.
The first paragraph mentions that by the end of 2050, nearly 80% of the population of the Earth will shift to urban centers.
The third paragraph mentions how this practice will go a long way towards lowering the requirement for shipping, plows, and tractors, considerably reducing fossil fuel consumption.
The third paragraph discusses how all food and crops may be organically produced, neglecting the inorganic products of pesticides, herbicides, and fertilizers.
The first paragraph talks of how, by making use of the conservative estimates in the present demographic trends, the human population density will increase exponentially up to three billion.
The fourth paragraph states how besides the advantages, a major setback of vertical farming is that the plants need artificial light, unlike traditional farming.
These are the answers that you should note very carefully. These answers, if practiced will give you an idea of how to grasp the core concepts from any passage before answering.
