Step 1: Match the first description

The first description is about a devastating earthquake in Haiti, which is a natural disaster. It causes food insecurity, infrastructure damage, and people fleeing due to lack of basic necessities. So this matches with "natural disaster".

Step 2: Match the second description

The second description is about overpopulation in Niger leading to job scarcity and migration, which relates to changes in population (demographic changes). Overpopulation is a demographic factor causing resource competition and job lack. So this matches with "demographic changes".

Step 3: Match the third description

The third description is about the Russian military invasion of Ukraine, leading to death, injury, and disrupted economic activities, with millions becoming refugees. This is a violent conflict (military invasion is a form of violent conflict). So this matches with "violent conflict".

Final Matches:
