In addition, agriculture plays an important role in the provision of extensive work for the people. Large firms and moderately wide, employ workers to undertake the various tasks in the cultivation of crops and care of farm animals. In most countries of the world, feed, agriculture remains the largest sector for employment and a large percentage of the population.

Agriculture is also in view of assessing the level of development of a country, based on the important skills of its farmers. Poorly trained farmers can not for the advanced methods and new technologies. The importance of science and technology in the development of agriculture is very clear in the words of Deng Xiaoping -

The development of agriculture depends first on policy, and the second on science. There is no limit to the development of science and technology, yet the role they can play in the field of agricultural development. ”

Although agriculture often plays a role in the non-contributory “Gross domestic product” – GDP – of most countries, it is nevertheless requires a substantial boost to the local and the international community.

Agriculture is traditionally in the manufacture of bulk basis. The harvest is performed once per season, mostly, and stored and later. In fact, some thinkers believe that people have begun to “batch processing” and “agriculture” in the industry to adopt, by the thought of farming practices. Before industrialization, people were with the largest supplies of food and other supplies as stable, and they were able to meet the challenges of nature, without hunger meet.

So important is the role of agriculture, “created” to keep that new concepts in order to give the traditional activity of a modern tower. Such a new concept in the world is raging these days – the meaning of “organic agriculture”. There is evidence that, apart from the many advantages that organic farms are more sustainable and environmentally friendly, so that agriculture is a new dimension.

The importance of agricultural practices was further established when ‘Organic food’ began as a small movement decades ago with gardeners and farmers rejecting the use of conventional non-organic practices. With the growing market for organic food is now much higher than that of the food industry, many large companies have ventured into. With the advent of multinational corporations, and with the creation of a legal framework such as the Soil Association certification, it is clear that the definition of organic food will change, making it more of a business that ever!

In fact, modern agriculture has undergone a great change since antiquity. Today the importance of agriculture is that it practiced both for subsistence and commercial reasons!

Primitive Origins and Middle Ages

Agriculture has long been depicted in cave drawings and appears in many manuscripts. The oldest civilizations began around rivers because it delivers water and nutrients it provides the field. Egypt and India were believed, the most fertile land for the seed, no wonder he called the cradle of civilization was to possess. From 7000 BC, Egypt was achieved in agriculture. This paved the way for waves in the ancient Sumerians developed agricultural techniques such as irrigation and cultivation of land and increase production. The Greeks have a figure for her, Demeter, goddess of Olympus, that the large grain and bread. It describes the source of human existence. Making it one of all the gods worshiped. The 1500s began their journey and settlers took part in the global exchange of crops such as potato, tobacco and cocoa beans. Spices of the New World were brought back to the old. Soon, the barter system for improved fuel jewelery, ceramics and even.

Different production methods

Today, almost the same concept of cultivation methods with the small difference of advanced equipment and scientific processes to be practiced. Fight against the parasite is one of the most performed because of the abundance of pests and diseases that crop. Pesticides are one of the fastest ways of pest control are still due to the chemicals that cause lethal effects on humans when they are taken discouraged. Soil preparation is both a form of struggle against the pest and nutrient enhancer. It prepares the ground for sowing. Other techniques for nutrient management include the use of fertilizer and compost, crop rotation and proper watering.

Organic and inorganic

The demand for organic foods has increased considerably over the years. People are more aware of what they eat and in turn become more aware of how their food is grown. Organic foods are foods that are grown and maintained without chemical pesticides or genetic modification. In grocery stores, organic products are usually “All Natural” or “100% organic”. The demand for agriculture will undoubtedly continue to grow as the years progress. Until people another source of subsistence agriculture are free of content, it will always stand as our livelihood.

Some complex problems like global warming, changes in eating patterns, climate change and poor agricultural production caused a sharp rise in food prices worldwide and the number of people who are malnourished, either among themselves or starve, which was a problem for the politicians.

Hunger crisis in Africa

For the third time in the Sahel in West Africa suffers from poor harvests, drought and food prices. Last year, Kenya, Somalia, Djibouti and Ethiopia were the worst hunger crisis and the government of the country are affected by the promotion of investment in land. The investors see great value in investing in farmland and buy farmland outrights targeting or sub-sectors in agriculture as fertilizer. The main trick of the investment is to produce part of agricultural production, the high returns in the form of regular crops helps because it is the growing demand for food grain on the world market and you also get results in an increase in the price of farmland.

Growing food needs

Investment in agriculture relates to trade in commodities and the farmers use agricultural contracts to offset losses in agricultural production. Agriculture has a growing bond of friendship between China and Africa. In 2050 the world population by 34% is greater than the present population, as it reached $ 9.1 billion and the demand for cereals will increase by 50% by 2030, according to statistics from the UN. Poor weather and increased demand from emerging countries, it will be difficult to regulate food prices.

The dangers of climate change and urbanization

Climate change is the biggest risk to the long-term food security. Climate change has a negative impact on agricultural production and urbanization also affects 70% of the world’s population, since it is the number of people who are reduced in the rural agricultural sector. To meet the growing population who earn money to feed and earn more, an increased amount of food grain production needs and the world will need at least 70% more grain.
