The Wheelbarrow Motion Theory: Climate Change and Corruption as Interdependent Drivers of Irregular South-To-North Migration – Practical Solutions and Policy Responses

Abstract

Irregular migration from the Global South to the Global North has increased alongside intensifying climate stress and persistent governance failure. Existing migration frameworks often examine environmental pressures and corruption separately, limiting their capacity to explain sustained irregular migration and the limited effectiveness of deterrence-based policies. This article proposes the Wheelbarrow Motion Theory to explain how climate stress and corruption interact to generate and sustain irregular migration. A critical narrative review was conducted using peer-reviewed literature, multilateral agency reports and policy evaluations published between 2000 and 2025, with empirical illustrations drawn from Africa, Latin America and South Asia. The review shows that climate stress erodes livelihoods and coping capacity, while corruption weakens adaptation, distorts relief delivery and restricts lawful mobility pathways. When these forces interact, displacement becomes structural and resistant to containment through border enforcement alone. Predominant policy responses centred on securitisation, deportation and migration externalisation have rerouted rather than reduced migration flows. Irregular migration is best understood as the outcome of interacting climate and governance failures rather than isolated drivers. Effective mitigation requires integrated approaches that combine climate adaptation, governance reform and expanded legal mobility options, rather than deterrence-centred strategies alone.
