The role or snow in the catchment The role of snow in the catchment is quite important. Although the upper catchment is moderately wet, the lower catchment is extremely dry. In fact, the lower catchment is one of the driest areas in New Zealand. It receives less than 400 mm of precipitation annually. Thus, the snow is imperative because when it melts, it runs down into the lower catchment and provides a water source that would not exist otherwise (because the lower catchment does not receive much rain). Additionally, most of the farming occurs on the lower catchment, thus relying on the irrigation from the melted snow source from the upper catchment.
The little impact summer rain events have on observed river flow The impact that

The relation between climate change and irrigation-related withdrawals and how important they are in determining the amount of water in the Lindis River The relation between climate change and irrigation-related withdrawals is quite important. It is hard to separate the two and decide which one is more imperative. With comparing that data above, I have concluded that the two are closely related and significant to address. They are both play a large role in determining the amount of water in the Lindis River. However, in my opinion, I think that irrigation might have slightly more urgency due to the fact that there are abstractions in the irrigation and they are not tightly monitored. Additionally, irrigation is easier to address do to the fact that it can be more controlled by humans than climate change. Better irrigation systems can be put into place that control water flow more accurately. Better management strategies can be developed in order to have a better structure of employees and management chain. This better-controlled irrigation can lead to an improved handle on the river water and less waste and uncertainty.
The possibility to continue some level of irrigation in the climate change scenario without further drying out of the Lindis River
The possibility to continue some level of irrigation in the climate change scenario without further drying out the Lindis River, in my opinion, is quite doable.
The first main issue that needs to be addressed is the
In addition, global climate change will exacerbate these challenges faced by countries and populations. Shifting precipitation patterns threaten to reduce water availability in some regions while inflicting stronger storms on others, increasing both potential droughts and floods. This may increase the frequency of more serious
The type of irrigation system we have watering our crops can and will help either bring the drought back or conserve as much water as we can. Since our main objective is to conserve and save as much water as we can looking into the different and better irrigation systems would be the best idea that we can be looking into.
This town, Winnemucca, is right in the middle of the Great Basin Desert which is in the middle of a drought crisis. Since this drought started here, it is causing the climate to change dramatically. Every year since I can remember, Winnemucca has received less and less snow and rain. Our lakes, rivers, and reservoir are showing and proving that. Rye Patch, which is a reservoir a few miles west of Winnemucca, used to have plenty of water to fill it enough to be three quarters up the boat ramp. Now this reservoir has a record breaking low. This reservoir is so low, you cannot even put a fishing boat in
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.
The western prairies provinces (WPP) have an area of two million km2, these regions are the main agricultural and food producing regions in all of Canada (Schindler, 2006). As global warming increases, more water will be used for irrigation for crops. Every year, 2.5 km3 of water is used for irrigation on 1 million acres of land. The water comes from reservoirs and lakes that trap snowmelt run-off from the Rocky Mountains, however only twenty percent of this water is returned to the rivers. The WPP temperatures have increased by 4 degrees since 1970 (Schindler, 2006. Most of the rural areas are not receiving 14-24% of their previous annual precipitation in the 1900’s. The summer flows have decreased 20-84% due to the increased warming through its effects on evapotranspiration and evaporation (Schindler, 2001). Low water flows can cause an escalation of water retention that results in increased nutrient retention, thus proliferating Eutrophication. (Helmer,1999). This imbalance between water evaporation, water usage and water replenishment will create scarce resource for Western Canada’s near future.
As we all understand, the Earth has many landmarks and it is these physical features that create an abundant and organized system within which we thrive. One of the most abundant natural resources on the planet is water and the importance of this element is as crucial as any other. For the fortunate few who get to utilize it, this amazing reserve provides us with our necessity for daily consumption as well as our ability to grow just about anything we please. Common irrigation practices are essential for gathering water into a contained area to grow crops that would not typically survive in areas without heavy rainfall. As a matter of fact, “irrigation is an ancient practice that originated along the Tigris and Euphrates Rivers in what is now Iraq” and is now the result of an estimated 40 percent of all crops grown around the world (Water Encyclopedia). This tactic has provided many different cultures with numerous varieties of crops as well as growth in crop yield which in turn dramatically advances human civilization. As we develop into a more progressive society, the tools and systems used to grow our crops also become more intelligent as well as sustainable
However, many of the worlds irrigation systems are found in arid, semi arid environments, which climate change will alter significantly in the future (J. D, Connor, Schwabe, K. King, D. Knapp, K. 2011). Nearly one third of the worlds Nearly one-third of the irrigated land worldwide are affected by salinization (Schwabe et al., 2011e).
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
If those measures still aren’t enough and water is taken from the basin faster than the water cycle can replenish it, a reduction in the amount of demand from farming
As a result of the drought rain is scarce, so when it does rain we should take a full initiative to direct it to our advantage. Rain does so much for the Earth as it filters the air, provides water for plants, and replenishes streams and lakes. When rainwater is not doing any of these tasks it is going to waste flooding
HANAK, E. (2015). The Drought Is a Vital Stress Test for the Future. Environmental Forum,
“Arid and semi-arid environments, which represent a substantial portion of Earth's surface, have remained poorly studied. Yet water scarcity and salt content, changes in rainfall, flash floods, high rates of aquifer exploitation and growth of desert regions are all signs that suggest climate change and human activities are also affecting these arid and semi-arid zones” (Buis).
If we keep on taking water for granted and wasting it, eventually all the world will go through a drought stage. Think of this as the end of the water where people are fighting over water just in order to survive. On the second article called 10 Ways to Help Our Ocean, it teaches all of us significant ways on how we can prevent water from vaporizing and the lands from becoming completely drought. We just need to remember that if we have a rainlessness environment, we won’t have any water, meanwhile, without water then we will all fail in prevailing to
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
There are a variety of causes held responsible for the water crisis in Africa. These causes have been taken from African’s control and desperately need to be solved. Climate change is one of the countless reasons that there is a high demand for water in Africa. An article entitled “Africa’s Water Crisis Deepens” written for the 2006 News Scientist, states that Drought, famine and spreading deserts have plagued Africa for the past 30 years. With the expansion of desertification, the process in which land becomes increasingly dry with little to no water resources, areas of land have dried out and are useless to humans due to the lack of rainfall on the African continent over the past several years.
