Among the 113 countries measured in the 2022 Global Food Security Index, Nigeria is ranked 107th overall, putting it deep in the bottom ten globally.
Nigeria has the lowest affordability score globally in the GFSI 2022, scoring only 25.0 in that pillar.
The country performs marginally better in other pillars: its score in “Quality and Safety” is relatively higher (55.6), and “Sustainability and Adaptation” is 53.7. But other pillars like “Availability” (39.5) remain weak.
Globally, a group of countries, including Nigeria, DR Congo, Sudan, Venezuela, Burundi, Madagascar, Sierra Leone, Yemen, Haiti, and Syria, all cluster at low overall GFSI scores (below ~45), reflecting severe challenges.
Russia is the volume leader with 37.3M carats, nearly 1.5× Botswana’s 25.1M carats.
Botswana punches above its weight: though producing 33% fewer carats than Russia, its output value almost matches Russia's due to higher value per carat price.
Eight of the top 10 producers are African (Botswana, Angola, DR Congo, South Africa, Zimbabwe, Namibia, Sierra Leone, Lesotho).
Low-volume producers like Namibia (2.4M ct → $1.2B) highlight how smaller deposits can yield high-value diamonds.
Gabon imposes Africa’s highest international air travel tax at $297.70, followed closely by Sierra Leone at $294 and Nigeria at $180.
Libya charges the lowest air travel tax among the listed African countries at just $1.30, with other low-cost countries including Malawi ($5.00), Lesotho ($5.70), and Algeria ($9.80).
All of the 10 most expensive countries charge over $100 in departure taxes, suggesting a trend of high levies among a subset of African nations.
The gap between the highest and lowest air travel taxes in Africa exceeds $296, revealing significant disparities in passenger costs across the continent.
