Essay on Mismanagement of Water Text

Jonathan Friesen - Writing Coach

In europe most vegetables and fruits are produced in the mediterranean countries, which are located more southern. There are the benefits of a longer growing season and more sunlight compared to other countries. But on the other hand there is often not enough water from rain available during summer to grow all plants. But the food market needs and wants the products at the end of the growing season. So the plants get irrigated to save the farmers income and the food for other people.

It is calculated as a ratio of the net benefits from the term water productivity was introduced to measure the benefits of water used in agricultural production. It varies from region to region and from field to field and is dependent on many factors 1.

Essay writing service essay marking service place an order irrigation is not a bad thing farmers invented to harm the ecosystem or steal good water. Irrigation is a consequence of trying to fulfil the needs and wishes of us humans. But there are not only the obvious plant production systems which are dependent on water, but also livestock production.

Table 1 shows the average daily water requirements of livestock in different situations. As a consequence of breeding and the wish to get even more litres of milk per day from one cow, these high performance breeds need even more water to produce so many litres of milk. A higher milk production combined with a greater need on water might not be a problem in developed countries, where water supply is not a problem. But if such breeds are exported to countries where this is not the case, it also might cause problems.

On the one hand we need good quality water but on the other hand we also need enough food. And as the population on earth is still rising, the situation is about to get even worse. The keyword now is very good management on how these two topics can deal with each other.

This could be achieved with effective strategies of water saving and a more efficient water use in agriculture. A starting point could be to train farmers and give them information, teach them how to use irrigation the right way and even more efficient. Mismanagement has direct effect on the fertility of the land and a lot of land has been lost due to salinisation. The problem itself is not just the loss of nutrients from the soil, because they are not the only thing on the fields.

Nowadays fertilizers and also pesticides are extracted on the fields and as a result end up in the soils. Too much water or wrong timing of irrigation can lead to eluviations and furthermore pollution of groundwater. No doubt, to run an intensive agricultural production fertilizers and pesticides are probably needed. This would not just have positive effects on the environment, but also on the ecological situation of the farmer.

Essay on Collective Responsibility

Pesticides are quite expensive and wrong timing of use can lead to little or no effect on the fields, nevertheless costs money and even worse: it can pollute the groundwater. There is no clear data yet about the effects of irrigation systems on biodiversity 4. Animals are fed crops the farmer has produced on the field and the nutrients of the feed goes back to the soil as manure. Manure spreading as an organic fertilizer is ecologically and economically beneficial, but again: the right timing is very important! this essay has been submitted to us by a student. Who wrote this essay request removal example essays if manure is spread out on frozen grounds it results in high levels of contamination of groundwater 5 , because the soil cannot bind the nutrients from the manure.

As a result there is less beneficial effect on the soil, but nutrient loss and water pollution. So again, the farmers have to know about this risk and how they can spread the manure in a more appropriate way. In regions with a very intensive livestock production there might not be enough land to spread all manure.

In developed countries it can be used for biogas to produce energy, but in some other countries all of the manure is spread out on the field, although it is more than what is needed and good for the ecology. Fact is, that agriculture has and will always have a huge impact on the natural resource water. The faster this happens the better it would be for the world and the people who live on it. Yes, we need food to survive, but is it really worth to risk our health and pollute our drinking water therefore? this should not be the price people have to pay to have access to enough food. There has to be another way to make both possible to stay healthy, have access to good drinking water and get enough food to eat. The theoretical knowledge, which scientists all over the world are working on, has to be taught to the farmers.

A relatively easy way to save some water could be to calculate the correct time of the sowing. Farmers usually know their fields and the weather conditions around time of sowing. This information can help the farmer to decide about the correct time to sow the seeds and can also save water. Another aspect to not solve but maybe reduce the water problematic a little could be found in plant breeding. In regions with less rain during summer period, there should grow plants and crops, which can deal with this situation of little water supply. Plants and crops, which need less water to survive and nevertheless have more or less the same production/harvesting level, can help the farmer and the ecology to reduce water demand. Next to providing good and helpful information for the farmer, another quite big issue of saving water might be to develop technologies to help the farmer applying water on the field.

Is Capital Punishment Right Essays

Only if this happens the water productivity can be maximised 4 and at least the water, which is used for irrigation can enhance a greater profit. Maybe right now we are not yet affected directly, but if we don't start to do something now, we also have to think about how to get access to good drinking water. After some time the polluted water from rivers and lakes ends up in the groundwater we want to use. Print reference this reddit this india's supply of water is rapidly dwindling mainly due to poor handling of water resources. the united nations designated 2003 as the year of fresh water. There is some grim irony in the huffing and puffing over the impact of the climate change and the danger of carbon emission because we don rsquo t pay serious attention to environmental issues until consequences are felt to be too grave to ignore attention. But the warning by the national centre for atmospheric research in colorado, usa mdash based on research carried out on the water flow of 925 major rivers from 1948 to 2004 mdash that availability of fresh water could be severely compromised by climate change, is a serious enough prognostication to warrant the fear that future wars on earth are going to be waged over water.
