human activities that deliberately or accidentally finish into rivers and other water bodies or streams. These wastes finally reach the sea and other water bodies where aquatic life. With the increased use of plastic, the respective waste management has become a problem, since many types of plastic (unlike other wastes such as wood) are not biodegradable and, therefore, accumulate. Plastic dragged through the water is dangerous, because it represents a serious threat to fish, seabirds, marine…
groundwater. The amount of water it takes each year to produce food for the whole human race is enough to fill a canal 10 meters deep, 100 meters wide, and 12.1 million kilometres long, long enough to encircle the globe 180 times. Impacts include water degradation, the depletion of rivers and groundwater as well as eutrophication when excess nutrients enter the water courses and cause algal bloom. Rivers are drying up because of greater agricultural production and water consumption and…
Organization), 2000; Gregorio, 2005) land cover refers to the biophysical cover of the earth surface or land for instance vegetation cover such as forest, shrub/bushland, and grassland and water. Whereas land cover can be defined as the attributes of the earth’s land surface covered by vegetation, desert, water bodies like lake, sea, ocean, bare soil and ice (Chrysoulakis et al., 2004; Lambin et al., 2003). Land use is characterized by the arrangements, activities and inputs people undertake in…
health. Clean water is crucial to any living organism, sometimes helping to dilute pollution (Carpenter et al., 1998). However, water runoff an issue relating to pollution, comes from the every day agriculture. The wasted soil and other contaminated materials find their way down into estuaries and ponds causing massive destruction to not only the water, but to the animals living there as well. Eutrophication, however, is the “biggest problem in most coastal waters,” making the water even more…
which compared to all other documented years, is the lowest on record (Viñas). LINK: Along with less ice in the Arctic, results in more water added to the oceans. More water in the oceans result in less area for animals like the polar bear to live and a rise in water levels. Less land for polar bears eventually results in the extinction of their species and higher water levels leads to a unexpected change in the…
Use of geothermal energy and boosted MED to have a stand-alone desalination, design of a prototype for water mass production based on hydrologic cycle principles (idea behind cloud formation, move of water as body without surface), use of cloud seeding techniques to increase condensation rate in thermal desalination (i.e. use of nuclei to increase water vapour condensation in industrial scale), and conceptual design of new desalination technology based on anatomy of loop of Henle in marine…
on how to solve this problem. Freshwater Resources Numerous resources in this world are going into scarcity due to overexploitation. Additionally, overexploitation…
inadequate rainfall has made things worse for the country. b) Scarcity of water leads to increased level of desertification: Botswana is going through severe water shortage due to inadequate rainfall and no water resource being available to tap in the land locked country. Higher and more focused efforts into the mining industry, coal extraction for electricity generation has rendered the underground water sources (the sources of portable water in Botswana) contaminated and in accessible. The…
with Pinus sylvestris to produce industrial timber. The Western concept of monocultures also developed in the 18th and 19th centuries in Europe because of the scarcity of timber,…
systems and fed in stalls, or made into silage or hay (FAO, 2015). The young leaves and shoots are edible to humans (Burkill, 1985) and considered as the second generation energy source crop in the USA (EPA, 2013). Elephant grass requires high levels of water and fertilizer. According to Francis (2004), yield range from 20 to 80 t DM/ha/year under high fertilizer inputs. With no or inadequate fertilizer, yields are in the range of 2-10 t DM/ha/year. Cuttings can be done at 45 – 90 day interval…
