Agriculture refers to the production of goods through the growing of plants, animals and other life forms on earth. In 2006, 45 percent of the world population is employed in agriculture. However, the relative importance of agriculture has declined since the beginning of industrialization. While agriculture employs one third of the world population, agricultural production accounts for less than 5 percent of global gross domestic product.

Agriculture is important not only to provide food, but also provide the raw material for other industries such as textiles, sugar, jute, vegetable oil and tobacco.

It is a vicious circle in which environmental degradation affects agricultural productivity and agricultural practices affect the environment. To complete agriculture, agricultural science and technological devices to reduce hunger, improve life and increase economic growth.
Local and indigenous agricultural practices must be used in conjunction with research and scientific development. There should be coordination of international scientific programs to improve agriculture and agricultural products. It is imperative to reduce hunger and to investigate the causes of food insecurity and degraded natural resources.
