From “the race to be the gateway to Eastern and Central Africa.” Below is a wild example of how geography matters and affects surprising aspects of life. Landlocked countries import a lot more stuff so their inbound roads get noticeably distorted from all the weight.
Historical economic stunting means that landlocked countries typically import more than they export and ship small volumes (thereby missing out on economics of scale). The stark disparity in imports/exports is often visible in the form of disproportionate road damage from overweight trucks (or poor engineering) on inward-bound lanes (see image of the road near the Kenya/Uganda Malaba border post).
For more details on how to this might change:
Kenya and Tanzania are in a race to be the gateway to Eastern and Central Africa, an economic catchment area with a population of 200m and GDP of $250b (USA=$23t). The DRC current accounts for the largest share of transit cargo through Tanzania. Uganda accounts for the lion’s share of transit cargo through Kenya. However, the spirited competition between Kenya and Tanzania risks creating over-capacity in the short run (population growth will guarantee demand in the long run)
