Invest in agriculture. Right now agriculture is in huge demand and the population is booming meaning more people need to be fed. My father already owns a huge farm and makes tons of money by selling his products to Hargeisa a city of over a million people. The locals benefited from his farm since he employed the locals to work at his farm.
There are many areas back home that are suitable for cultivation and it would be great if people can take advantage of it. It's getting tiring seeing people building new hotels and restaurants when there are many untapped areas you can invest in that can make you a fortune.
