First, this is almost 20 years ago and irrelevant today, and second, you should show the whole text:
"In comparison to Hargeisa, Bosasso residents enjoy a higher standard of living if we compare average daily incomes. While urban residents of Hargeisa earn, on average, about $1 a day, Bosasso residents earn over $4. Naturally, with respect to Bosasso, IDPs earnings are far lower. Most IDP households in Bosasso earn a daily wage of a little over a $1, which is more than 50percent, more than most returnee/IDP families living in and around Hargeisa. However, for Bosasso's IDPs these earnings are seasonally dependent.
There is less economic activity in Bosasso's main port during the summer months and since most IDPs work in activities associated with port trade, the figures cited above reflect earnings during the more busy winter months. Many IDPs said that since job opportunities decrease greatly in the summer, they often migrate southward towards Nugal and Mudug regions of Puntland. However, the significant income earning opportunities for IDPs explains the fact the most cite shelter, health and food as priorities rather than job opportunities . Nevertheless, conditions for IDPs in Bosasso are the most severe in northern Somalia."
Today the situations for IDPs can only be much more worse in Puntland compared to Somaliland, since IDP's don't have access to US dollar and nobody is accepting the Somali shilling anymore in Puntland.
