year, within our SSA segment, Tenants increased by 738, including 487 from Colocation, 199 from New Sites and 52 from the reintegration of previously lost tenancies more than offsetting Churn, while Lease Amendments increased by 2,106.
Segment Adjusted EBITDA was $76.5 million for the second quarter of 2024, compared to $62.9 million for the second quarter of 2023, an increase of $13.5 million, or 21.5%. The increase in segment Adjusted EBITDA primarily reflects a decrease in cost of sales of $27.4 million driven by a decrease in tower repairs and maintenance costs, security services costs and power generation costs of $11.3 million, $8.2 million and $7.7 million, respectively, primarily due to the unwind agreement discussed above. This was partially offset by the decrease in revenue discussed above. None of the updates to gross revenue and cost of sales discussed above have a net impact on segment Adjusted EBITDA.
Latam
Revenue for our Latam segment decreased by $1.9 million, or 3.9%, to $46.5 million for the second quarter of 2024, compared to $48.3 million for the second quarter of 2023. The decrease in revenue was driven by the non-core impact of negative movements in FX rates of $2.5 million, or 5.1%, partially offset by organic revenue growth of $0.7 million, or 1.5%, which grew despite a $5.3 million reduction in revenue from our customer Oi S.A. in Brazil as a result of their judicial recovery proceedings. Year-on-year, within our Latam segment, Tenants increased by 661, including 927 from New Sites and 215 from Colocation, partially offset by 424 Churned and 57 in net divestiture, primarily due to the disposal of Peru, while Lease Amendments increased by 127.
Segment Adjusted EBITDA was $33.3 million for the second quarter of 2024, compared to $35.3 million for the second quarter of 2023, a decrease of $2.1 million, or 5.8%. The decrease in segment Adjusted EBITDA primarily reflects the decrease in revenue discussed above, and an increase in power generation costs and tower repair and maintenance costs of $1.2 million and $0.4 million, respectively, partially offset by a decrease in site rental costs of $1.5 million.
MENA
Revenue for our MENA segment increased by $1.3 million, or 12.7%, to $11.1 million for the second quarter of 2024, compared to $9.9 million for the second quarter of 2023. Organic revenue increased by $0.6 million, or 6.4%, driven primarily by New Sites and escalations and grew inorganically in the period by $0.6 million, or 6.4%, driven primarily by the sixth stage of the Kuwait Acquisition. Year-on-year, within our MENA segment, Tenants increased by 138, including 109 from Tenant Acquisition and 36 from New Sites, partially offset by 7 Churned, while Lease Amendments increased by 14.

INVESTING ACTIVITIES
During the second quarter of 2024, capital expenditure (“Total Capex”) was $53.7 million, compared to $201.9 million for the second quarter of 2023. The decrease is driven by lower capital expenditure across all our segments with Nigeria, SSA, Latam and MENA reduced by $106.2 million, $18.8 million, $20.8 million and $1.7 million, respectively.
The decrease in Nigeria was primarily driven by decreases of $41.0 million related to Project Green, $27.0 million related to maintenance capital expenditure, $20.5 million from augmentation capital expenditure and $14.5 million for fiber business capital expenditure. The decrease in SSA was primarily driven by decreases of $6.6 million in refurbishment capital expenditure, $5.6 million related to New Sites capital expenditure, $5.4 million in corporate capital expenditure and $2.5 million in maintenance capital expenditure. The decrease in Latam was primarily driven by decreases of $8.4 million related to New Sites capital expenditure, $7.5 million for fiber business capital expenditure, $2.6 million relating to purchase of land for new or existing sites and $1.8 million in corporate capital expenditure. The decrease in MENA was primarily driven by decreases of $0.8 million related to New Sites capital expenditure, $0.6 million in other capital expenditure, and $0.2 million in maintenance capital expenditure.
The total capital expenditure incurred on Project Green from commencement until June 30, 2024, was $205.7 million, of which $0.1 million related to expenditure incurred in the second quarter of 2024.
