No. While there are too many people with too little food the situation is not caused by overpopulation but other factors. To quote for the article above:
Until recently, Zimbabwe was one of the region's more stable and self-sufficient countries, and neighbors often turned to it for help during food shortages. But the government's efforts to seize land from white farmers, who own more than half the country's fertile land, have disrupted production greatly. The combination of severe drought and farm seizures has been disastrous.
Production of the corn crop in Zimbabwe plunged by nearly 70 percent this year, leaving almost half the population in need of emergency food. With triple-digit inflation, a limp currency and rising unemployment, Zimbabwe can barely help itself, let alone its neighbors.
The problem is not too many people but not enough planting and harvesting. This is partly caused by the drought but mostly caused by stupidity in high places.
