The field of international development has been shaped by a diverse set of theories, each offering distinct perspectives on how societies can achieve progress. From the linear growth model of modernization theory to the structural critiques of dependency and world-systems theories, these frameworks have influenced policy, funding priorities, and program design for decades. The rise of sustainable development reframed progress as a multidimensional goal, integrating environmental and social considerations alongside economic growth. More recent perspectives—post-development and de-growth—challenge the very foundations of traditional development, advocating for culturally grounded, ecologically responsible, and non-growth-oriented approaches. This paper examines these key theories, highlighting their conceptual foundations, critiques, and implications for contemporary non-profit practice. Understanding their strengths and limitations enables practitioners to design development initiatives that are contextually relevant, inclusive, and sustainable.
