You're being really ignorant sxb. The latest population conducted by the U.N estimated the Somaliland population to passed 4 million. Somalia overall is almost 15 million. Also, you're talking about Puntland which is a full desert, really hot and has a population between 1 million to 2 million. Hargeisa alone is 1.3 million or possibly more.
Somaliland does have the capability to withhold enough population. Remember major cities like Hargeisa and Burco aren't hot but cool. They have enough fertile land and enough abundance of water but it's just the fertile lands aren't fully cultivated and they don't have the technology to distribute enough water or safe water which is why Somaliland are taking big measures of increasing the economy so they can hold alot of population in the future, inshallah.
