Kenya recorded the highest ivory seizure among the top 10 countries, with 130,432 kg confiscated over the 34-year period.
China and Hong Kong follow closely, with 106,069 kg and 75,707 kg seized, respectively, showing their long standing roles as critical players in the global ivory network.
Vietnam and Singapore, both located in Southeast Asia, had substantial seizure records; 71,256 kg and 29,882 kg, indicating persistent trafficking through the region.
Nigeria leads West Africa in ivory confiscations within the top 10, with 23,031 kg, signalling its importance as a key node in the transit chain.
All countries listed in the top 10 are either source, transit, or destination points in the global ivory supply chain, reflecting how widespread and interconnected the illegal trade remains.
Somalia has the lowest AIDI score in Africa at 7.10, reflecting extremely poor infrastructure across all sectors.
South Sudan (7.38) and Niger (8.12) rank slightly higher, showing similarly weak infrastructure profiles.
Ethiopia (13.09) and the Central African Republic (13.23), though more advanced than others on the list, still score under 15.
Nigeria's AIDI score of 25.70, while not high by global standards, is more than three times higher than Somalia’s, indicating major disparities in infrastructure across the continent.
Goodluck Jonathan's era (2010–2015) delivered the highest AIDI growth, with a CAGR of 6.84%, more than double that of his successor.
Muhammadu Buhari’s administration saw steady but slower growth, with a CAGR of 2.63%, increasing the score from 20.60 in 2016 to 25.70 in 2024.
Musa Yar’Adua’s brief tenure (2007–2010) still managed a solid CAGR of 4.26%, indicating promising momentum that was cut short.
Nigeria's AIDI score rose from 8.61 in 2003 to 25.70 in 2024, nearly tripling in two decades.
Obasanjo’s tenure saw the slowest growth, with only a 2.59% CAGR, suggesting limited infrastructure expansion in the early 2000s.
The fastest absolute annual increase occurred between 2010 and 2014, when scores jumped by over 2 points per year.
Despite steady growth, Nigeria's 2024 score of 25.70 still places it far from top performers in Africa, showing that significant infrastructure gaps remain.
