also have devastating effects on the soil making sure that forests and other plants cannot regrow in that area. Once the vegetation and plant life is eradicated from the area, soil erosion and a loss in soil fertility will become an accumulating problem. According to the National Department of Agriculture (1999), Soil erosion is the act of soil, or more specifically the nutritious top-soil that plants depend on so much, being washed away by rain, streams, or any other flowing water source (para. 9).

meet the demands of potential evapotranspiration.The main factors responsible for such widespread hazardous scarcity conditions are major deformity in the rainfall patterns, indiscriminate cutting of trees, large scale deforestation,and massive soil-erosion. Due to the severity of the drought condition people need to work together as a whole and find solutions to solve this problem. Although there are ways to overcome drought, it has become a very serious issue throughout the nation because of the climate

reduces the scattering. • In agricultural lands the receiving water is contaminated by nonpoint pollution due to different agricultural activities like crop production, cattle operations, crop pattern and rangelands. • High rates of surface runoff and erosion of land covered by annual crops have high levels of turbidity in receiving water specially in spring when vegetation cover is minimal. • Wetlands used in removal of bacterial contamination in rivers , act as biofilter which increases the turbidity

The question of what factors lead the Mayan’s to their end is arguably history 's most enduring mystery. Every society has its rise, and inevitable fall. However, none have fallen quite like the Classic Maya society. Like many civilizations, the fall of the Classic Maya society hinged on the back of many contributing factors over the time span of 660-900 A.D. There are many contributing factors that contributed to the demise of the society. These factors consisted of climate change, deforestation

have this food in the future and we wouldn’t be using pesticides and fertilizers as they effect human health and they aren't sustainable in the long run. We can plant crops like clover or hairy vetch when soil would usually be bare to help prevent erosion of the soil. These crops also replenish soil nutrients and keep weeds in check which then prevents the use of herbicides and fertilizers. Planting a variety of crops can also have many benefits, including healthier soil and improved pest control,

Val Plumwood in her essay “Paths Beyond Human-Centeredness,” illustrates the impact that humans have on nature and non-animals when it comes to preserving environments. Understanding that nature has it’s living properties that let it thrive among its resources allows for people to grasp the complexities that come about when construction companies destroy the environment in which they work. Plumwood uses the term dualism to refer to the sharp distinction between two classes of individuals. There is

Effects of Drought Natural phenomenon along with being very beautiful and useful for humankind, sometimes become very disastrous and demolishing for them. They show a negative side of nature and indicate some very demolishing aspects of nature, which the humans cannot ignore because of possessing less power. These incidents remind people that they do not have the control over everything and they are very small in front of such natural calamities. However, with strategic and wise planning one can

7 Study Figure 7. (a) Suggest why many countries find El Niño weather anomalies very challenging.(10) El Nino is referring to the dramatic change that occurs in the walker circulation cell and in other areas but I am going to focus on this specific area, where the usually south-easterly trade winds going from west of South America to Australia and Indonesia across the Pacific Ocean reverse or severely weaken. This occurs usually every 3-7 years and can last between 12-18 months. During an El

harvest. Land degradation is exhibited as deforestation, decreasing biodiversity resources, soil moisture stress as well as soil erosion. The following report will be assessing the socio-economic as well as the environmental impacts of soil erosion and land degradation impacts in the Ethopian Highlands of Tigray. The severe land degradation is a result of the soil erosion as well as the nutrient depletion. Throughout the past years soil and water conservation techniques have been comprehensively introduced
