Wow this is really interesting. As a hobby farmer deep in the south of Ghana I even get frustrated with the free range cattle herders here, goats and sheep. It is not only Fulani but many other opportunists living in around this growing half developed area.
The land I work is not mine otherwise I would put up a good permanent fence but I am building a modular electric fence based off of solar to keep animals out and I will be adding some goats and pigs so I will be keeping them in. I will surely post on this. I can not wait for things to change or get into arguments with the local alajias I also have to take responsibility for my open farm.
