We all should improve the habit of water saving and conservation in our home and outside. Here are some points which can help us in save water outside the doors:. Good morning to the excellencies, my respected teachers and my dear colleagues. I would like to speech on the topic of save water today while celebrating such a nice occasion.
5 Reasons Why Water Conservation is Important for Your Family
Hope you all would help me and let me fulfill the objectives of my speech. As we all know the importance of water in our life. Water involves in almost all the processes in our body such as digestion, elimination, assimilation, respiration, maintaining body temperature, etc. It is required to remove the thirst of our body.
We can live for days without food however cannot imagine to live without water more than a day. Water is required by everything like plants, animals, microorganisms, human being, etc to fulfill the body requirements. Do we imagine that what will happen if the drinking water get finished a day or get polluted. Yes, it is the main question which has opened the eyes of everyone and start saving water at every place we belong like home, surrounding area, office, school, college, etc.
We have to save and conserve our drinking water from extra spend as well as being polluted by following various techniques of water conservation. Now-a-days, in the world of technological improvement and industrialization, the safe water is getting polluted to a huge level on daily basis by getting mixed with hundreds of tons of toxins and impurities as industrial wastes. There are many water treatments used to make dirty water clean and bacteriologically safe however many times they have been proved ineffective because of the presence of certain pathogenic bacteria giardia and cryptosporidium after test.
Sometimes the presence of toxic chemicals and inorganic minerals are also found causing various diseases.
In order to be safe from the diseases, a mass of people has started drinking mineral water. If we regularly destroy and soiled our drinking water, surely there would be a day soon when we get pure water labeled as oxygen enriched, free toxic materials, radioactive and chemical compounds. Here are some points helping how to better save drinking water:. A very good morning to the excellencies, respected teachers and my dear friends.
I am here to speech over save water topic today on this great occasion. A sequel to the deforestation is typically large scale erosion , loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation , cover crops , conservation tillage and planted windbreaks , affect both erosion and fertility.
When plants die, they decay and become part of the soil. Code defines standard methods recommended by the U. Natural Resources Conservation Service. Farmers have practiced soil conservation for millennia. In Europe, policies such as the Common Agricultural Policy are targeting the application of best management practices such as reduced tillage , winter cover crops,  plant residues and grass margins in order to better address the soil conservation. Political and economic action is further required to solve the erosion problem.
Essays on water conservation
A simple governance hurdle concerns how we value the land and this can be changed by cultural adaptation. Contour ploughing orients furrows following the contour lines of the farmed area. Furrows move left and right to maintain a constant altitude, which reduces runoff. Contour ploughing was practiced by the ancient Phoenicians , and is effective for slopes between two and ten percent. Terracing is the practice of creating nearly level areas in a hillside area. The terraces form a series of steps, each at a higher level than the previous.
Terraces are protected from erosion by other soil barriers.
Terraced farming is more common on small farms and in underdeveloped countries, since mechanized equipment is difficult to deploy in this setting. Keyline design is an enhancement of contour farming, where the total watershed properties are taken into account in forming the contour lines.
Tree, shrubs and ground-cover are effective perimeter treatment for soil erosion prevention, by impeding surface flows. A special form of this perimeter or inter-row treatment is the use of a "grass way" that both channels and dissipates runoff through surface friction, impeding surface runoff and encouraging infiltration of the slowed surface water. Windbreaks are sufficiently dense rows of trees at the windward exposure of an agricultural field subject to wind erosion.
Cover crops such as legumes plant, white turnip, radishes and other species are rotated with cash crops to blanket the soil year-round and act as green manure that replenishes nitrogen and other critical nutrients. Cover crops also help suppress weeds.
Soil-conservation farming involves no-till farming , "green manures" and other soil-enhancing practices. Such farming methods attempt to mimic the biology of barren lands. They can revive damaged soil, minimize erosion, encourage plant growth, eliminate the use of nitrogen fertilizer or fungicide, produce above-average yields and protect crops during droughts or flooding. No-till farming and cover crops act as sinks for nitrogen and other nutrients. This increases the amount of soil organic matter.
Once damaged, soil may take multiple seasons to fully recover, even in optimal circumstances. Critics argue that no-till and related methods are impractical and too expensive for many growers, partly because it requires new equipment.
