Capacity Development as a Foundation for Achieving the Sustainable Development Goals

Abstract

This study examines why capacity development matters for SDG delivery and assesses whether current approaches are adequate for achieving the 2030 Agenda. The research synthesises recent scholarship and policy guidance to clarify the relationship between institutional capacity and SDG implementation outcomes. A convergent mixed methods case study design was employed across four purposively selected national and subnational contexts. The quantitative strand comprised a survey of 263 respondents (policymakers, civil servants, researchers, NGO representatives, and community leaders) using validated capacity and SDG implementation indices. The qualitative component consisted of 20 in-depth interviews that explored mechanisms and constraints. Data collection employed systematic sampling, structured instruments, and thematic analysis, following established protocols for integrating mixed methods. Composite capacity development combining individual competencies with organisational systems correlates strongly with SDG implementation outcomes (r = 0.59, p < .001). Domain analysis reveals systematic disparities: individual competency domains (strategic planning, stakeholder engagement) averaged above 58 points on a 0-100 scale, while organisational domains (data management, regulatory capacity) remained below 51 points. Local ownership amplifies the capacity-implementation relationship by 39%, with three key mechanisms identified: institutional incentives that align career advancement with SDG priorities, coordinated rather than fragmented external support, and authentic local control over development agendas. Results indicate that traditional training-focused approaches successfully build individual competencies but struggle to strengthen organisational systems. Organisations should sequence system investments alongside individual training. Donors should prioritise coordination mechanisms over individual project delivery. Local ownership should be operationalised through governance structures rather than treated as a rhetorical commitment. The 17-point performance gap between the highest and lowest performing cases on organisational domains suggests that systems investments, rather than individual training, differentiate institutional effectiveness. This study provides empirical evidence to support theoretical claims about the effectiveness of capacity development, while also demonstrating the moderating role of local ownership in translating capacity inputs into implementation outcomes. The mixed methods approach illuminates both statistical associations and underlying mechanisms, contributing to debates about technocratic versus participatory approaches in development cooperation. The research provides a validated framework for measuring multidimensional capacity, which can inform future programming and evaluation across SDG domains
