Self-Sufficient Islands

Living self-sufficient on Private Islands

If an island can offer its owner not just a living space, but also drinking water and enough food to be able to have a healthy diet, we are talking about a self-sufficient island.

Every family which already tried to get by without the additional purchase of groceries knows that, after a while, one finds the best way to provide for oneself: Whether one decides to grow fruits and vegetables while buying meat and milk on the mainland, or to keep animals for oneself; whether one eats the fish from the surrounding waters or the fish from the fishermen of the next village—how independent one wants to be on one’s own island depends on the personal lifestyle and standards. And the island technology also requires individual planning: is a high tech satellite station preferred, or a simple telephone, a solar plant or a generator? 

Almost every climate zone features islands that can be used as self-sufficient islands. A reliable rule of thumb from the days of the settlers of the 19th century goes thus: 2.5 acres of land are enough to feed one family. Regardless of whether the island owner wants to take up intensive farm work or seeks relaxation on his island—it is a rewarding feeling to be able to fall back on the riches of nature.

Temperate Zone

Extreme temperatures and precipitation are rare in these regions and the average temperature ranges from 30 to 70 °F. Lush, green forests, warm wetlands, and steppes characterize them. The mild yet moist climate and the abundance of daylight present good conditions for farming.

Subtropical Zone

Long, warm summers and mild, moist winters are predominant in the subtropical zone. The diversity of flora is relatively low: green rain forests alternate with savannas and semi-deserts.

Tropical Zone

Most of the earth’s warmest climatic zone is characterized by the diurnal climate: The temperature differences between night and day are bigger than the differences between the monthly averages. The vegetation ranges from evergreen rain forests to savannas. More than 40 percent of the world’s population lives in the tropics—with an upward trend.
