This is an old article that shows two possible franchising opportunities. First the “ready-to-use, prepackaged irrigation kits” are a possible candidate for product franchising. Explore around on IDEI's website and particularly look at their product list.
The Bollywood-style instructional video is also a potential franchise business. A franchisee could acquire one of these modified vans and travel to villages to show movies. A primary source of income could be from companies who wanted to run ads before the movie. This could also be a wonderful mechanism to share public health messages.
