HUMAN FACTORS IN AGRICULTURE
Human factors that influence agricultural use include:
Population size leads to larger areas of cultivation and competitio for land.
Farming techniques. In developed countries, modern techniques, which include mechanisation and fertilizers, have increased production. In less developed countries, traditional techniques keep production lower.
Final destination of production. In subsistence agriculutre, the farm family cultivate all they can. Production is intended for their consumption. In contrast, commercial agriculture often specializes in one crop. Production is intended for sale. To minimize the costs of transportation and keep products frech, cultivation should be near markets.
Globalisation. Economic globalization means countries can sell their production to other countries. Producers must compete in quality and price. This leads to intensive production techniques.
Agricultural policies. Governments influence agriculture with: agriculture reform laws; hydrological plans for irrigation new land; economic aid to farmers (to help buy materials and machinery); production quotas and, occasionally, restrictions on imports.
Environmental policies aim to protect the environment and guarantee safe, healthy food. Policies regulate irrigation, use of fertilizers, pesticides and treatment of waste.
PHYSICAL FACTORS IN AGRICULTURE
The main physical factors that make agriculture possible or impossible are:
Climate. Some crops grow better in one climatic zone than in others. In general, plants cannot grow in areas with very high temperatures (above 45°C) or very low ones (below 10°C). They cannot grow in areas with too little rain or too much rain.
Landscape. Relief (altitude and the gradient of terrain) influences agricultural activity. At higher altitudes, temperatures descend, and this limits species development. Gradients of terrain above 10° make it impossible to cultivate the land. Consequently, agriculture usually takes place on plains or in valleys. However, where it is necessary, hard work can transform mountain sides into cultivated terraces.
Soil. Plants nedd soil with certain characvteristics. The grain size and porosity of the soil affect the amount of oxygen the soil contains, and its ability to retain water. The chemical and biologicl comostition of soil determines its degree of acidity and the quantity of mineral nutrients and organic matter.
