  Geography: American Southern Coastlands

  “Of anywhere in the united states it is in the southern coastlands that the climate has greatest impact on human geography. There are several factors which affect human activity: humid subtropical, long growing season, mild winter temperatures and warm humid summers. There are 9months or more of potential growth for agricultural crops for almost the whole region of the southern coastland. What is more the average annual rainfall is more than 125cm mostly between April and October when warm temperatures support plant growth and sunlight is plentiful. It is enough rain for most agricultural activities for almost the entire region. These climactic conditions have brought forth 2 important results: farmers can grow their crops until late in the fall without fear of frost as long as agricultural conditions are met. I mean as long as there is fertile soil, control of insect pests and appropriate ground drainage. It has even been possible to harvest 2crops and even more for vegetable farmers. Of greater importance is the fact that there is the chance to produce specialty crops that cannot be produced in other parts of the United States. Although the region where citrus fruits have been produced has slowly moved southwards along the peninsulas interior citrus production. Citrus production has been noteworthy in contributing to Florida’s economy. Of the 7 major citrus growths, in Florida orange and grapefruit are most important. Most oranges, about 80% today, are processed rather than being sold fresh.

  The processing of oranges has had affects on other parts of the economy as more people are employed in the industry and sales are not limited to the harvest period but continue all year long. The grapefruit is produced in a similar area as the orange, but the demand and output is only about 25% of the orange. These 2 citrus fruits are also grown in south Texas but with irrigation. Production costs for citrus fruits mainly come from harvesting. The fruit must be picked by hand from the trees. During the harvesting season thousands of migrating laborers flock to Florida to do the physically strenuous in the citrus groves. In the mainland United States it is only in the southern coastlands sugar cane production is found. It is in production all year round and needs more than one year to reach full maturity. It is intolerant of frost and needs a large amount of water more than 125 cm per year. Rice has fewer climactic requirements than sugar cane. As long as rice has sufficient water it will mature according to the amount of heat it receives in the summer. In Louisiana and Texas rice is grown with irrigation. Besides specialty crops there are parts of the southern coastlands which are one of the countries main areas for growing vegetables. In the winter urban markets are filled with fresh vegetables grown in Florida and along the southern part of states along the gulf.”
