Investment in physical infrastructure - roads, bridges, power plants, hospitals, schools, airports, sea ports, water ports, railways etc. - is a fundamental ingredient in the growth and economic development of a country. Compared to countries like Singapore, South Korea and China, countries in Sub-Saharan Africa have significantly underinvested in infrastructure over the years, resulting in stunted growth. Kenya has a large infrastructure funding gap, and with ballooning government debt, the country cannot solely rely on the government to meet its infrastructure funding needs. This study looks at the two predominant infrastructure funding models in Kenya, government funded procurement and public-private partnerships, to understand the salient features of each of the models and the causal relationships between them, before embarking on a process of creating a new model that results in the benefits of both. This systematic combining method emancipates the researcher, allowing the study to make use of Roger Martin’s process of integrative thinking to innovate new models for funding transport megaprojects in Kenya.
