THE Role of Law in Structuring Sustainable Finance for Infrastructure Projects in Sub‐Saharan Africa: A Comparative Study of Nigeria, South Africa, and Kenya

Journal of Critical Infrastructure Policy, Volume 7, Issue 2, Fall/Winter 2026.
ABSTRACT Sub‐Saharan Africa (SSA)'s infrastructure deficit is not fundamentally a consequence of insufficient capital but rather of legal and institutional failure. This article argues that law is a decisive factor in determining whether infrastructure finance becomes possible, functioning not merely as a background condition but as a mechanism through

Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

New Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Synergizing Public Incentives and Private Capital: A Hybrid RAB‐RBF Framework for Low‐Carbon Energy Infrastructure Access in Low‐ and Middle‐Income Countries

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.
ABSTRACT Regulated asset base (RAB) and results‐based financing (RBF) are key emerging infrastructure finance models, offering stable returns (RAB) and outcome‐based incentives (RBF). This perspective proposes a hybrid RAB‐RBF model to bridge the “viability gap” in developing regions and catalyze low‐carbon energy infrastructure access where cost ...
