Water is the only natural commodity on Earth that has no other substitute where all life forms depend for maintenance and survival. It also plays a significant role in various human activities. Water resource is very abundant on the planet but because of rapid urban development and high population, water consumption is dramatically increasing especially the demand for domestic water use. Because of this, water resources are slowly depleting which has resulted in water scarcity in certain areas around the globe. Water scarcity is one of the major environmental predicaments that the world is facing at the present and the Philippines is not spared from that. According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA, the Philippines may experience water crisis by 2020. Moreover, provinces in Luzon like Cavite will eventually suffer from water scarcity by the end of 2018 due to the decrease of water resources in highland areas such as City of Dasmariñas and Silang, based from …show more content…
The said activities reduce the water infiltration into the ground surface hence producing surface runoffs that flow into channels and streams which may carry contaminants that might pollute the surface water. In addition to the increasing of impermeability, removal of soil and vegetation, and grading the land surface escalate the amount of runoff volumes (Novak, Giesen, & DeBusk, 2014). As a watershed is developed and urbanized, a large amount of the vegetation is being replaced by impermeable surfaces, thus reducing the zone where intrusion to groundwater can occur. In result to this, more stormwater runoff is being produced – runoff that necessarily be collected by extensive drainage system (USGS,
Do you ever feel like there is a piece of dry, and scratchy piece of sandpaper in the back of your throat from not having enough water? How would you feel if you could never stop the anoying feeling, that is constantly reminding you, that you could die from extreme thirst any day from now. The main reasons that China was driven into the intense water shortage is, their Government policies, Population increases and the most tremendous reason is the industrialization of China. One of the main reasons that is driving China's unfortunate water crisis is, China’s tremendous population growth. As China’s cities are increasing in population more of their residence are consuming their limited water supply.
Runoff in streams and rivers is a massive problem in the Southeastern United States, along with other parts of the world. While each area has different elevations, soil types, and vegetation, it shows that it is a constant problem that all areas show. The definition of runoff can be complicated or simple, depending on the person who explains it. The effects of runoff, seen throughout the different areas, can affect the ecosystem. The ecosystem can be affected by the leading cause of runoff, erosion.
When one thinks about Colorado one thinks about the mountains, wildlife, and rivers. Colorado is a beautiful state that has so much land and wildlife to offer, it’s a state that is full of peace and tranquility with all its environment that it provides for our population and tourists. However, due to population growth and climate change Colorado runs the risk of going through a water crisis. Conservation Colorado is the largest environmental nonprofit organization in Colorado. Fighting for Colorado to be able to keep its beautiful wonders intact and to prevent from suffering from a water crisis by fighting for our state to conserve its water and prevent it from suffering a water drought.
From: Mr.Jazayeripour the manager of Mojave Desert community to: The California Environmental Protection Agency Water is one of the necessary sources for organisms to survive in many ways. and did you know that (The United States uses about 346,000 million gallons of fresh water every day. allaboutwater.org-water.facts ) Mojave river, colorado river and underground water are the main sources of water for animals, plants, residential, industrial and agricultural uses. ground-water depletion is primarily causes by sustained groundwater pumping.
River has provided protection from flooding but not from the dangers of an inefficient water cycle and a lack of ecological diversity (see figure 2). Pouring concrete into the bed and banks of rivers allows for the water to flow at a much faster rate. The ability for water to infiltrate the ground is non-existent when there is concrete surrounding the water. Without the ability to penetrate the ground, the amount of runoff is increased dramatically. A large decrease in one area of the water cycle only leads to a large increase in another.
Impervious surfaces like roads and parking lots prevent rainfall from being absorbed into the ground, resulting in an increase in stormwater runoff that brings pollutants into the Bay.
If there is another water crisis it will affect many things. Water crises are bad in many ways so don’t pollute the
4. Habitat alteration: Removal and reduction of natural habitat by flooding, soil erosion and water
This leads to soil erosion. The water carries away the eroded soil and the eroded soil may be deposited in rivers. Rainwater flows quickly into rivers during heavy rain because there is no reservation of water by plant roots as well as water catchment areas. Due to oozing in the rivers, the water flow is slowed down and become blocked. Thus, water flow interior and causes flash floods in low areas.
Industrial waste can also create polluted runoff that collects in rivers and lakes. Another reason for water pollution is chemically treated sewage. This water carries harmful chemicals and high amounts of bacteria, which can potentially lead to serious diseases. Runoff from fields can contain chemical fertilizers and pesticides which can pollute
Singapore is a country with no rivers or lakes to tap for fresh water. Due to these natural constraints, Singapore faces a serious issue with the supply of fresh water for consumption. Singapore’s only source of water is rainwater. In the early days of the young nation, very little
Topic: Water Shortage Specific Purpose: To inform the audience about water shortage and how to cope with water scarcity Thesis Statement: Across the globe, reports reveal huge areas in crisis as reservoirs and aquifers dry up. I. INTRODUCTION A. Turning off the water while brushing their teeth, a family could save about 5 to 10 gallons of water per day. B. Freshwater shortage will cause the next great global crisis.
2.8.2 Urbanization Urbanization led many areas becomes more modernized. Lowland areas have been reclaimed by taking land from the hills. There are also small rivers that filled up to be used as a building site. Activities such as these are a common factor of flooding. In the past, creeks and valleys turned into water flow, now the area has been covered with soil.
2.1 Urbanization and river water quality Due to movement of people from rural to urban areas, physical growth of the urban areas occurs, which ultimately leads to the urbanization, Over the past several years, river systems have always been extensively altered to meet various human demands, which led to them becoming the most intensively influenced ecosystems by human activities on the Earth (Nilsson, et al., 2005 )]. ‘’Among these human activities, the influence of urbanization on river systems was the most significant, and 60% of river systems were changed profoundly because of urbanization in the world’’ as cited by (Nilsson, et al., 2005 ) Recently, a number of studies have been done to understand the effects of urbanization on river water quality. The study manifested on Pearl River Delta Economic Zone is in China, that there is a positive correlation between the rapidity of urbanization and the pollution levels of urban river water.
Introduction By the year 2025, the Philippines is believed to be brought to a water crisis if no new sources of water are developed or found to meet the growing demand of the citizens. (Sapnu, R., Balabo, D., & Cervantes, D., 2007) "There is a Japan International Cooperation Agency study that says that if we will not conserve water, there may be some problems. But of course we can always start conserving now and look for other sources," Lopez (2013) said. Studies have shown how water conservation and appropriate water utilization are significant as early as today.
