Water Crisis in Pakistan

As the days are becoming hotter, and as our water supply is decreasing, it is becoming more relevant than ever before to increase the water inventory for the agricultural industry. With the damming of the Hetchy-Hetchy river, it will limit our already low supply and output of crop, which is the lead export of sustenance in the nation.

This essay is a review of the article “Growing More Food with Less Water”, written by Sandra Postel. According the article, our global freshwater sources, including underground aquifers and rivers are stressed beyond their ability to provide freshwater. Agriculture redesign is necessary with the two primary goals being to cut water demands of mainstream agriculture and bring low cost irrigation to poor farmers. Typical irrigation, crop furrow flooding is a main cause of wasted and polluted water. This article discusses alternatives to typical irrigation. These alternatives have been tested onsite by farers and surveyed.

Many people know that water is essential for human-being and it is not only valuable for health and life, but water is also important for industry and agriculture. Furthermore, use of water has a spiritual, cultural and recreational dimension. However, water resources are not infinite. Wide and inefficient use of water resources can lead to irreversible consequences, such as water shortage. This essay will firstly discuss the problem of water shortage on examples of developed and developing countries and include the diversification of the same issue in the different parts of the world. It will also identify causes and effects of this environmental problem on society and other spheres of life. Moreover, in this essay I am going to propose

As an American citizen, I never question the water my state government provided me with. Also, I took for granted that I was receiving purified water, and believe that I did not have to inquire about the water safety level. However, after reading the Kristen Silven article, “Flint Water Crisis”, I felt infuriated learning that an American community had been poisoned, because of their government inadequacy to provide them with proper water. Also, I believe it was inhuman that the government neglected citizens and their duties for nearly 18 months. Furthermore, I felt empathic for the 666 homes that have shown high levels of lead poison in their drinking water. I could not imagine being a mother watching my child be poisoned and not have the

Have you ever thought about how much water you waste each day? If you haven't, than that is pretty normal. People in America have it so good here because they can just walk to a fossate and get clean water. But in other parts of the world it is not that easy. They have to walk long treks just to get water that is not even clean.

(Hasan and Özay 2002, 73-74). As Albiac (2008) reports, development of pipe network distribution and drip irrigation methods in other countries led the farmers to have remarkable irrigation efficiency in drought (143). Such technologies have already been used in China, but they are not widely spread in China’s agriculture. One investigation in China on rice paddy irrigation systems development was performed and it revealed that using the fry-foot paddy irrigation (when no water flooded the field) instead of flooding irrigation (when the rice field is completely flooded) significantly (40-60%) reduces water consumption (Xiaoping, Qiangsheng and Bin 2004, 351). Furthermore, drip irrigation method was applied in arid Northern China and it raised the water usage efficiency (Du et al 2007). However, introduction of new irrigation technologies faced some difficulties in China. As Hodstedt (2010) noticed in his article, the water saved by these technologies such as drip irrigation systems was simply spent on more food production and, therefore, did not reduce the water shortage. Also, as he reported, this caused two other environmental problems. Firstly, the water, which was the supply for underground water and aquifers as it was lost by deep percolation and leakage, became unavailable after the water-saving technologies were introduced and this strengthened the aquifers depleting along with its overpumping. Secondly, after

The loss of freshwater comes from The Basin’s flow level it is dangerously reduced by extreme and persistent drought conditions. The hand of man makes these conditions much worse. The major upstream tributaries

Water is found everywhere on earth : from ice-covered lakes to tropical rains, yje surface of our planet is covered with almost three quarters of water. However, water is still one of the most precious resource for humanity : only 2.5% of water is pure. Water is therefore a renewable but no unlimited natural resource which is at the center of many debates : considered as the most sever threat in the world, water shortage crisis is spreading in the news. This essay will discuss the following : first, we will see how water is linked to everything; ten we will see that water crisis has a lot of repercussions on developing countries and their growth. Finally we will discuss

This state lies in the Northern part of India, covering an area of 50,362km2. The major population centers are Ludhiana, Armritsar, and Jalandhar, with populations all hovering around one million (“Census of India”, n.d.). In 1947, Punjab was divided into two separate states, with half residing in India and the other half in Pakistan. Punjab has always been a rich agricultural region. Since 1998 however, Punjab has consistently had below average amounts of annual rainfall. The climate across Punjab rarely ever sees temperatures drop below 0 degrees celsius, and is classified as subtropical. The state is known for outputting 40-50% of the rice and 60-65% of the grain of the country's total production. To make up for the deficit or rainfall and increased need for irrigation, there has been a 600% increase in the amount of tube wells in the past 35 years alone (Aggarwal et al, 2009). This large increase in wells and groundwater extraction has led to a decrease in the water table by up to 2m in the past 20 years (Singh, n.d.). Just like California, Punjab’s drought is starting to reach a critical level, and practices need to change in order to replenish the ground

Water can be considered the most important nonrenewable resource in the world. Every human across the world needs it in order to live and it carries a lot of value. The world is now at a stage where the scarcity of water is making people nervous because groundwater is at an all-time low. Several wars over the years have arisen in the Middle East for water. Desert is the many land condition that rules over the Middle East which means drier air, sand, and minimum water available. This is not a light issue since blood is being spilled over the control of certain rivers and dams within the area. Tension over control for water sources will only worsen as fresh water availability decreases.

water scarcity is the biggest threat to our food security. agriculture uses about 70 percent of all our freshwater from rivers every single year from around the world. river water is used to irrigate farms and feed billions of people around the world. the level of threat to the ongoing supply of fresh water available depends on the place. river systems and the water that the farmers capture store and distribute are the most threatened natural environments on earth. an increasing demand for water is by far the most common threat to food security around the world. with so much water being used it is easy to run out of the water what makes the crops die of dehydration.

To begin with, during the 100 years, the sector of agriculture had the highest water consumption and its figure experienced a dramatic increase, reaching 3000 km3 in 2000. The gap between water used in industrial field and domestic field widened through the years despite starting at almost the same level, with around 1200 km3 and 300 km3 water used respectively in 2000.

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

It is an essential resource for sustaining life as well as central to agriculture and rural development, and is intrinsically linked to global challenges of food insecurity and poverty, climate change adaptation and mitigation, as well as degradation and depletion of natural resources that affect the livelihoods of millions of people across the world. According to the World Bank, (2010) report, water is a scarce resource with multiple interwoven uses that range from drinking water, energy, irrigation, manufacturing things, transport of people and goods among others. The report further states that, more than one-sixth of the Worlds’ population does not have access to safe drinking water, with 80% living in rural areas thus access to water cannot not be guaranteed globally.
