Agrarian activities (agriculture, livestock farming and silviculture) are conditioned by natural and human causes that influence them to a high degree. Physical factors: - Climate - Relief - Soil and vegetation Human factors: - Demographic pressure - Technology - Economic and social organization

Physical factors:
Climate: temperatures, precipitation, winds or sunlight hours determine the crops cultivated in a place.
Relief: montainous areas suffer more soil erosion and make difficult the use of machinery. That´s why flat terrains are more suitable for agriculture while livestock farming and silviculture are practised in mountains.
Soil and its characteristics have important effects on crops. The amount of nutrients, its capacity to retain water or its acidity determine its accuracy for agrarian activities.
Vegetation determines silviculture and livestock farming.

Human factors:
Demographic pressure can lead to deforestation in order to dedicate bigger areas to crops and pastures. It can also foment overexploitation.
Technology:
Traditional societies use basic tools and natural fertilisers.
Advanced societies: use modern machinery, chemicals and modern techniques such as greenhouses.
Economic and social organization:
Depending on the destination of production agrarian economies can be subsistence economies or market economies.
Property of land can be private or collective. Exploitation can be direct (the owner exploits the land) or indirect (someone else exploits the land in exchange of a rent)
