Downward spiral of conflict and famine in Somalia is due to the absence of good governance, not climate

Somalia is mostly dry and semi-arid with the exception of few areas of greenery in the northern mountains or the riverine agricultural fields in the south.

Satellite time series data are useful for studying biophysical how variables change over time and understanding what causes those changes. Recently, I was looking into correlating two time series datasets over Africa to look at the relationship between net primary production (NPP) and rainfall.After a futile attempt to find an “out-of-the-box” software package that does this, I created an R function to speed things up.
