Living Fences

I've got 2 hectares (8 acres) of land in wet/dry tropics of western Africa with a "total circumferential distance" (is that the right term?) of about 800 metres (+/- 2600 feet) which I want to fence, possibly leaving parts of it open to free roaming animals, yet still marking it in some ways so other people won't impose on my land. The best (or not?) would be a brick fence running the whole 800 metres, but I'm afraid that will be too costly. Perhaps a living fence would work... Been watching some vids this evening of cassava fences made in the tropics which look great, but I doubt I'll be able to find a gazillion cassava sticks in order to make a fence.

Any ideas of living fences in the tropics?

Circumference normally applies to circles, perimeter would refer to the shape you speak of.
Between spain and west africa, that puts you in the  Straights of Gibralter!
I am guessing there are issues of poverty, theft etc that exist in the area?
Can any fence be built that will not be taken or cut down for firewood?
Would wire fencing be affordable and would it be left alone?

I see from inspection that living fences are used, https://www.echocommunity.org/en/resources/5ee6afc7-aafd-4178-81c4-c219c54f6633
" Gliricidia
Gliricidia is a fast-growingnitrogen-fixing tree that grows up to 15m in height. It is used for living fences, green manure, fodder, honey production, wind breaks, and fuelwood. This tree tolerates dry, acid, alkaline, and salty soils and was traditionally grown to shade cocoa trees.
Leucaena
The genus Leucaena includes several multipurpose tree species and interspecific hybrids that can withstand almost any type or frequency of pruning or coppicing. They are native to Mexico and Central America, and now abundant in the Philippines, West Africa, Nepal, Australia and Hawaii. '

“Farmers near Kabale in Kenya describe traditions, now considered superstitious, that certain euphorbias cause cancer when planted near the homestead.” [Euphorbias in Africa fill many of the environmental niches that are filled by cacti in the Americas.] Now the carcinogenic effects of one common living fence species, Euphorbia tirucalli, have been described. The active carcinogen has been found not only in the plant itself, but in extracts from nearby soil, vegetables and drinking water. “The report suggests that Burkitt’s lymphoma, a common childhood cancer in East Africa, is caused in part by consumption of water and vegetables from sites near this euphorbia.”

The plant grows profusely in Kenya’s Eastern, Western and Nyanza Provinces and in parts of Tanzania. In southwestern Uganda it is widely planted as a living fence to exclude livestock from protected springs, suggesting the frightening prospect that water that has been assumed safe is in fact very hazardous. It is also commonly used as a living fence to protect food crops.

CONSIDERATIONS ABOUT LIVING FENCES
For western mind, tis knowledge is probaly well known in West Africa

What trees grow easily in your part of the world?

If you are just wanting to mark the property line you could plant a tree lets say every ____ meter?

This might also work with cassava.

The fill in the distance with other abundant plants or a debris fence or junk pole fence:

Dear John. Thank you for clarifying.

What I meant to say is that I own land both in the south of Spain as well as in west Africa (Senegal)

Both wiring and wood could work. Lots of people use a local hardy wood cut into 1.5 meter high poles (pretty sure tree is called Khaya Senegalensis) with a few rows of wire in between poles. I've seen some germans add some sonar panels and electrify that fence, but it still let's some animals and stray dogs in.

I've already planted some of those trees; Gliricidia and Leucaena - both of which have proven to grow really well in this climate. I would want a real fence which proves its purpose: protection and keeping things either in or out, one which is built once and lasts for many years.

The junk pole fence looks really cool!

I think Anne's idea of a dead hedge until you get a living fence established is a good one. I found a couple of threads on plants for tropical areas:

maybe one of these will help you with species selection.
