This post is the fourth in a five part series on a radical new approach to scaling BoP business models, what we call a transformative sector strategy. In this segment, I discuss the common characteristics that make BoP business models in different sectors scalable solutions.

Searching for Transformational Models in New Sectors

If building the missing infrastructure could transform rural connectivity and health care, what about access to clean drinking water, especially for smaller rural and peri-urban communities? That's a proposition that WRI and Santa Clara University's Global Social Benefit Incubator are researching. There are some promising models in the field, such as Water Health International, that are beginning to scale. There are a number of additional enterprises, five of which will be mentored intensively in this year's incubator class. There are some promising new filtering technologies that use less energy than existing technologies, as well as other interesting approaches that have yet to be applied in emerging markets; we are undertaking a detailed comparison of both existing and newer technologies.

A number of community-initiated business models have produced good results, but they aren't easily replicable and don't scale. So we are analyzing both franchising and public-private partnership business models. Many of the elements that make rural connectivity and rural health care promising appear to be present in the water sector. It is too early to say what will emerge out of the research, but the scale of the unmet need is clear - a billion people without access to clean drinking water.

And after water, why not BoP energy? Our preliminary thinking is that there at least three sub-sectors of interest: Off-grid power and lighting, from mini-hydro to LED lighting; efficiency improvements in energy-using devices, such as cook stoves and motorbikes; and locally-grown, produced, and consumed biofuels that don't compete with food. We know of prototype enterprises and projects in each sub-sector, some of them already beginning to scale. We believe that the recent, rapid evolution of technology options will continue and can be adapted for the BoP. And we know that the unmet need is very large.
