Role of Land Agricultural Sector

Note from Figure 1.1! This image is a dry soil conditions, arid, no plants can grow, as a result of the influence of erosion. Yet we know that in human land to plant crops to meet both the needs of food, clothing and housing. In other words it can be said that the land is a natural resource that is essential for fulfilling the lives of humans on the earth’s surface.
Figure 1.1 The soils damaged by erosion

Figure 1.1. The above, showed severe conditions such as soil erosion. What can be expected from such soil conditions? Yet we know that soil is a natural resource that is essential for agriculture, because it is a source of life for humans, animals and plants. Without human land will not be able to live, as well as animals and plants.

Humans as the holder of the mandate to protect and save the soil, it should understand the land and its properties, excellent physical properties, chemical and biological soil, so that people become more wise to use the land as a natural resource to meet the needs of human livelihood. Land as a natural resource in agriculture has a function or a very big benefit to human life.

Without the natural resources humans certainly can not meet the various needs and activities. Around us there is a land with various types and characteristics. Objects that every day we see and we tramped it has benefits vary, of course in agriculture land resources are used as a medium for the cultivation of plants. Land resources in Indonesia which is used as a production area of ​​agricultural cultivation can be divided into three categories, namely (1) the cultivation of food crops, (2) cultivation of plantation crops, (3) the cultivation of horticulture crops are fruit trees, vegetables, ornamental, medicinal and aromatic ,

Land is the land component in the form of a top layer of the earth’s crust is made up of minerals and organic materials and have the physical, chemical, biological, and has the ability to support human life and other living creatures. As we know the food chain from plant stems. Human and animal life of the plant. Indeed, there are plants and animals that live in the sea, but most of our food comes from the ground.

Therefore, it is our obligation to preserve the land so that it remains able to support life on this earth. However, as well as water and air pollution, soil contamination was largely due to human activity as well. Increased production of biomass (plant produced agricultural activities, plantation and forest plants) which utilizes ground control can lead to the destruction of land for biomass production, resulting in lower quality and soil functions that can ultimately threaten the survival of human life and other living creatures.

Some of the indicators concerning the results of the evaluation of the development of agricultural activities to date, namely (1) the level of land productivity decreases, (2) the level of soil fertility decline, (3) the conversion of agricultural land is increasing, (4) the breadth and quality of critical land increasingly widespread, (5) the level of pollution and environmental damage agriculture increased, (6) the carrying capacity of the environment degenerate, (7) the unemployment rate in rural areas increased, (8) the purchasing power of farmers is reduced, (9) the income and welfare of farm families declined, (10) the gap between communities increases.
