Are Water For Meet Global Demands For Food? 2050? Critically Discuss The Challenges And Suggest Potential Solutions

The consumption of water has been increasing in the last few decades. Most of the demand is caused by agricultural activities (BBC Features). Water needed for industrial purposes also drives up the demand. The world can learn about ways of conserving water from the countries that have initiated the measures and have become successful at it. Australia is considered as the most successful so far. Recycling, desalination, and harvesting rainwater are some of the solutions that can be applied to handle water shortages and create

According to the U.S. Bureau of the Census, the population of the world in 1955 was 2.8 billion; in the year 2014, the world’s population increased to 7.207 billion. According to World Watch, the population is expected to reach 8.1 billion people by the year 2025. As population increases, so does demand for pure drinking water, but changes in social attitudes and behaviors could redirect our present course and possibly curb the global population growth.

The world’s supply of water is in steep decline as more and more is being used each year by more and more people around the globe. Currently, 800 million people do not have access to a drinking source. At the current rate, 1.8 billion people could be living in areas of absolute water scarcity by 2025.

Without water, the lives of millions of children, and adults, are at risk. For children under five, water-and-sanitation diseases are one of the leading causes of death [4], along with malnutrition. [5] Unfortunately, studies show that in 2025, two-thirds of the world’s population will be water stressed. [6] If this proves to be correct, then will two-thirds of the world’s population be hungry? We use so much water to produce even the simplest of agriculture. It takes 2,000 to 5,000 liters of water to make food for just one person, not to mention that humans need to drink 2.5 liters of water daily. [7]

The water supply now and in the future affects the population in many ways. According to “Water in 2050”, the water supply is the determining factor of how large the population may grow. In some areas lack of

People often think that water will never be used up. There is plenty of water, such as rain, water from the rivers and wells. It seems as if water is always available around us and we never have to worry about water shortage. In fact water is rather limited on the earth. With the rapid increase of population and fast development of industries, water is more needed than before. At the same time, a large amount of water has been polluted and wasted every day. Some big cities in China are facing the problem of water shortage already. There, water supply is controlled and industry has been restrained.

The earth’s population is over 7 billion and growing. This has caused many people to question the provisions that will be provided in the future for the coming generations because of the overconsumption of individuals. The earth is already struggling to sustain its natural resources for the vast majority of people living here, so bringing more children will cause extra strain on trying to preserve them. Water is an example of a

The fourth reason for why we may run out of food by 2050 is due to Salinity. Salinity is the main reason as to why lesser crops are being grown. Salinity is caused by trees being cleared. When the trees are in the ground, their long roots keep the salt water further below the surface of the earth. When they are cleared the salt water rises to the top. This salt water kills crops causing production to slow as the farmers then have to find a new place to produce their crops. This problem can be fixed slowly by both not clearing trees from the land and planting more trees to push the salt water down further.

We usually associate water shortages with a lack of drinking water, but global water scarcity has a critical impact on food security. Agriculture consumes more water than any other source. Climate change is altering patterns of weather around the world, causing shortages and droughts in some areas and floods in others. Water is key to food security. Crops and livestock need water to grow. Agriculture requires large quantities of water for irrigation and various production processes. Water scarcity may limit food production and supply, putting pressure on food prices and increasing countries’ dependence on food imports

Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes

By the year 2050, the world’s population is expected to reach 9.8 billion people. To sustain this enormous population, it is absolutely critical to optimize production of food and water usage. Furthermore, as extreme weather such as droughts and floods become more and more frequent due to climate change, conserving water and increasing food production will become invaluable to sustaining human life.

The focus of this essay is how water shortages in the future can produce worldwide food shortages. “Only if we act to improve water use in agriculture will we meet the acute freshwater challenges facing humankind over the coming 50 years” [4]. As the world changes over the next fifty years, the water struggles that we endure will be seen in the food production around the world. There are many factors that contribute to this occurring, including global climate change, the increase in water security vulnerability, and the phenomenon that the world has hit peak water. The world’s population has also changed their average diet over the past 50 years, to consuming more meat and more calories in general [4]. This dietary change means that each person requires more water to produce their food than in previous generations.

According to UN-Water, 75% of planet Earth is covered in water. 97.5% of that is ocean and 2.5% is freshwater. 70% of freshwater is divided into glaciers and ice caps and the remaining 30% into land surface water, such as rivers, lakes, ponds and groundwater. Most of the freshwater resources are either unreachable or too polluted, leaving less than 1% of the world's freshwater, or about 0.003% of all water on Earth, readily accessible for direct human use. According to the Global Outlook for Water Resources to the Year 2025, it is estimated that by 2025, more than half of the world population will be facing water-based vulnerability and human demand for water will account for 70% of all available freshwater. Furthermore, a report in November 2009 by the 2030 Water Resources Group suggests that by 2030, in some developing regions in the world, water demand will exceed supply by 50% and a report jointly produced by more than two dozen U.N. bodies states that, "By 2030, nearly half of the world's

India’s agricultural sector currently uses about 90% of total water resources.[12] Irrigated agriculture has been fundamental to economic development, but unfortunately caused groundwater depletion. Due to water pollution in rivers, India draws 80% of its irrigation water from groundwater.[13] As water scarcity becomes a bigger and bigger problem, rural and farming areas will most likely be hit the hardest. Thus far, food security has been one of the highest priorities for politicians, and the

Water is the most precious resource this planet has to offer. A one of a kind substance, water is a resource that sustains all life on this planet. Yet, humanity supports an industry that uses water inefficiently and irresponsibly, one that takes more 42% humanity’s accessible fresh water and wastes it. Unless we take the proper initiative, our world’s water supplies will slowly deplete, leaving earth in an eternal drought, which could potentially cause an end to the human race. Agriculture is an industry that will cause water scarcity to erupt throughout the world if not changed from its irresponsible methods. As the world’s largest industry, agriculture uses 70% of our accessible remaining freshwater. In other words, the amount of water
