Map Of World Trade

The trade is of growing importance in the global economic context, because the portion of production goes to foreign markets has been increasing steadily. In the past 50 years the physical volume of global production grew 8 times while the volume of exports increased 25 times (in value 150 times.) One consequence of this phenomenon is the increasing interdependence of economies and the need to incorporate an international perspective in household decisions. Hence the importance of highlighting some of the characteristics presented by global trade.

Physical Factors Affecting Farming

Climate: Temperature – a minimum temperature of 6°C is needed for crops to grow. The growing season is the number of months the temperature is over 6°C. Different crops need a different growing season, e.g. wheat needs 90 days. Rainfall – all crops and animals need water.
Relief: Temperatures decrease by 1>°C every 160 metres vertical height.
Uplands are more exposed to wind and rain. Steep slopes also cause thin soils and limit the use of machinery. Lowland areas are more easily farmed.
Soils: Crops grow best on deep, fertile, free-draining soils, e.g. the brown earths found in lowland Britain. Less fertile soils prone to water logging are best used for pastoral farming.
Aspect: The direction a slope faces. South-facing slopes are best for growing crops.
