The Global Solution Capacity Gap: Human Security and The Structural Limits of Global Governance in An Age of Polycrisis

The international system of the twenty-first century is increasingly characterized by a condition of polycrisis in which armed conflicts, climate change, pandemics, forced migration, economic vulnerabilities, energy and food insecurity, digital transformation, and geopolitical competition interact rather than operate as isolated threats. This article examines a structural problem underlying these interconnected crises: the Global Solution Capacity Gap (GSCG). The central argument is that the capacity of the international system to generate, transmit, and amplify problems has expanded faster than its capacity to coordinate and implement collective solutions. As the geographical scope, interdependence, velocity, and complexity of global problems increase, institutional capacities for coordination, resource mobilization, implementation, and accountability do not necessarily expand at the same pace. The article integrates Robert W. Cox’s historical-structural approach, collective action theory, the global public goods literature, Elinor Ostrom’s polycentric governance perspective, scholarship on institutional fragmentation and regime complexity, and the human security approach. The article’s principal contribution is the development of a conceptual framework that defines the Global Solution Capacity Gap as the normalized difference between the demand for global problem-solving and the available solution capacity. It further proposes a five-dimensional Global Solution Capacity Index (GSCI) consisting of institutional coordination, crisis response capacity, implementation and compliance capacity, resource mobilization, and human security outcomes. The framework distinguishes institutional plurality from institutional incapacity. A plurality of institutions does not necessarily undermine governance; the critical issue is whether institutional interactions generate effective collective outcomes. The article therefore proposes that the central governance challenge of the twenty-first century is not simply the multiplication of crises but the widening distance between the systemic demand generated by interconnected global problems and the capacity of international institutions and actors to produce coordinated solutions.
