Plant Adaptations and Responses to Salinity Stress Despite the high salt stress applied‚ higher plants are able to adapt to these conditions. Salt exclusion and inclusion by higher plants serve as a response to high salinity. With the capability to exclude the salts‚ negative effects on the entire plant and certain organs are prevented or reduced. Due to the selectively permeable membranes of the plant‚ K+ are absorbed rather than Na+ leading to low Na+ levels and Cl- content in the plant

Introduction Water is known as a vital component to sustain life. When one is confronted with the fact that water is considered a renewable resource in the short term but only 3% is usable (N.Gray)‚ precautions must be taken to ensure the conservation of water. The agriculture industry consumes approximately 70% of the planet’s usable water globally. At large scale the water footprint arguably cannot be reduced‚ raising the question on whether our water is being used to its full potential. Water

Fresh water is one of the basic needs and essentials of all living things. Although organisms utilize it differently‚ we use it on an everyday basis. Without water‚ it is quite apparent to see that there would be no life. As most know today‚ California is currently in the midst of a drought that has been ongoing for four years. This epidemic has been getting worse and worse‚ which is a severe problem. Although being in a drought is surely an environmental issue‚ it is our responsibility to be mindful

Site concept narrative: The Clayey Overflow Ecological Site occurs throughout the MLRA. It is located on Stream Orders 2 or greater. This site is a run-in site and receive additional moisture through runoff from adjacent sites and overflow during occasional flooding. Typical slope range is from 0 to 2 percent. The soil surface layer is 5 to 11 inches in depth with a texture range of silty clay loam to clay. The natural vegetation will gradually shift from almost exclusively herbaceous species

1. Ramgnaga sub-basin description Ramganga is the first major tributary that joins to the Ganga with a catchment area of 32‚768 km2. Ramganga rises at an altitude of about 3‚110 m in the lower Himalayas near the Lohba village in the Garhwal district and enters the plains at Kalagarh near the border of the Garhwal district of Uttar Pradesh. Then‚ the river flows in a southeasterly direction and finally joins the Ganga on its left bank near Kanauj in the Fategarh district. The river flows entirely

Water is the basic requirement for living beings. About one sixth of the world population has no access to safe drinking water. Even though two third of earth’s surface is covered with water‚ fresh water sources accounts less than 2.5%. Out of this‚ only a small fraction of water is easily available for access to humans as the remaining is locked in glaciers and deep underground aquifers. Rising population and improved standard of living have escalated per capita demand for fresh water. India had

Flooding has led to serious geographical implications in Cork City‚ grid reference: W665 717 (Geoghegan 2008). The River Lee has a long history of flooding issues that have led to serious consequences economically‚ environmentally and educationally. In this essay I intend to analyse the causes for the River Lee flooding as well as the impacts that has geographically on environment and civilisation. Causes of flooding include the release of water from dams‚ flash floods and river overflow. Synchronously

Two Rainfall-Runoff Models were earlier identified for application and for the generation of a more reliable discharge data. These are the Thornwaite Water Balance Model (WBM) and the IHACRES. The input requirement of both models differ. For the WBM‚ generation of runoff requires seven input parameters. These are the Runoff Factor (RF)‚ Direct Runoff factor (DRF)‚ Soil Moisture Storage Capacity (SMSC)‚ Latitude of location‚ Rain Temperature Threshold‚ Snow Temperature Threshold and Maximum Snow Melt

Scarcity is often misinterpreted and not clearly understood‚ making it vital to realize the factors that make something scarce are limited resources exist‚ the product is desirable‚ and has more than one use. A resource with an available amount less than its preferred use is scarce. Throughout our developing world‚ we are discovering that more of what surrounds us is becoming restricted except with a lack of knowledge as to why or how to prevent it from occurring. As humans‚ we are continually putting
