What is a remote territory?
A territory is an area of land that belongs to or is looked after by a country. Some territories are not next to the main part of the country. They lie across the sea, often as islands or groups of islands. We call them remote or overseas territories.
Many such places have their own culture, rich nature (reefs, forests, rare animals) and often good sunshine and sea for tourism. But they also face problems that mainland places do not.
Maps at different scales
A map scale tells how real distance is shrunk on paper. For example, 1 cm = 1000 km.
- Small-scale map (like 1 cm = 1000 km): shows a very large area, such as the whole mainland and all its far islands. Details are tiny. It is best to see where things are and how far apart.
- Large-scale map (like 1 cm = 1 km): shows a small area, such as one island with its roads, port and villages. It is best to plan local work.
To find a real distance: real distance = map distance × scale. If two places are 6 cm apart on a 1 cm = 1000 km map, they are 6000 km apart.
To study a remote territory you need both: a small-scale map for its place in the world and a large-scale map for its inside.
Distance and island constraints
Distance. A plane flies about 800 km each hour. A cargo ship moves about 35 km each hour. So 8000 km is about 10 hours by plane but about 9 to 10 days by ship.
Island limits. An island has only a small piece of land. It may have little farmland, little fresh water and few minerals. Its sea around it makes it isolated: only ships and planes connect it, and bad weather can stop both.
Small market. With few people, a business cannot sell much, so big factories and many shops do not come. People may leave to find jobs on the mainland.
Specific development challenges
- High prices. Fuel, food and building goods travel far, so they cost more.
- Few jobs. Small markets mean fewer kinds of work. Many young people leave.
- Weak links. Few flights, slow internet and a small port.
- Natural risks. Cyclones, floods, rising sea and sometimes volcanoes or earthquakes.
- Care for nature. Reefs and forests are rich but easy to damage.
Ways to help
- Better port, airport and sea cables for internet.
- Local products: fish, fruit, spices, crafts, and tourism that respects nature.
- Solar and wind power instead of costly imported fuel.
- Schools, health care and online work so people can stay.
- Storm shelters and early warnings.
Try it
In the 3D, drag the distance slider from 500 km to 10000 km and write down plane hours and ship days. Then, at home, pick two cities in an atlas, measure the gap with a ruler, and use the scale to find the real distance. Predict first, then check.
Key formulas and definitions
- Real distance = map distance × scale (e.g. 6 cm × 1000 km = 6000 km)
- Travel time = distance ÷ speed
- Plane about 800 km/h; cargo ship about 35 km/h
- Small scale = big area, little detail; large scale = small area, much detail
Worked examples
1. On a map with scale 1 cm = 1000 km, an island is 4.5 cm from the mainland. What is the real distance?
Real distance = 4.5 × 1000 = 4500 km.
2. A plane flies at 800 km/h. How long does it take to cover 4500 km?
Time = 4500 ÷ 800 = 5.6 hours (about 5 h 38 min).
3. A cargo ship moves at 35 km/h. How many days does it need for 4200 km?
Time = 4200 ÷ 35 = 120 hours. 120 ÷ 24 = 5 days.
4. A map shows an island 2 cm wide and its real width is 20 km. Find the scale.
20 km ÷ 2 cm = 10 km per cm, so the scale is 1 cm = 10 km.
5. Name two reasons why a litre of milk may cost more on a remote island than on the mainland.
It has to travel a long way by ship or plane, which costs fuel and time; and shops sell small amounts, so the cost per item is higher.
6. Which map would you use to plan where to build a new school on an island, a small-scale or a large-scale map? Why?
A large-scale map, because it shows roads, villages and buildings in detail.
Common mistakes
- Mixing up the scales: a small-scale map shows a big area with little detail, a large-scale map shows a small area with big detail.
- Forgetting to change units: 4200 km at 35 km/h gives hours; divide by 24 for days.
- Thinking all islands are poor. Many earn well from tourism, fishing or services; the point is that they face extra challenges.
- Saying distance is the only problem. Small size, isolation and natural risks matter too.
