Using an ARDL bounds testing approach on Nigerian data from 1990 to 2023, this study confirms that while green and climate finance significantly drive long-term sustainable development, their current scale and structural limitations, alongside transitional costs and institutional inefficiencies, necessitate strengthened policy frameworks and expanded private-sector participation to fully achieve Nigeria's climate and development goals.

Topological characteristics, formation mechanisms and risk propagation simulation of global unmanned aerial vehicle industrial chain trade network

This study employs a "pattern-mechanism-risk" framework combining complex network analysis, ERGM, and cascading failure models to reveal that China's dominant role in the 2023 global UAV trade network drives a multipolar structure where supply disruptions in China trigger widespread global risk propagation, unlike the more contained impact of US disruptions.

Baseline Port Structure and Heterogeneous Responses to External Disruptions: Evidence from Major West African Ports

This study analyzes daily data from ten major West African ports to demonstrate that while baseline structural indicators like cargo diversification and trade imbalance characterize a port's functional position, they fail to serve as standalone predictors of resilience against diverse external disruptions such as the pandemic, the Russia–Ukraine war, and Red Sea crises.
