[Daba Finance] Tech entrepreneur Mark Shuttleworth is introducing a conservation-linked income program on Príncipe, a small island in São Tomé and Príncipe, where he owns several luxury resorts. Through his nonprofit Faya, up to 3,000 residents, about 60% of the island's adult population, will receive annual payments of as much as 20,000 dobras, or about $958. The payments will be distributed quarterly and are described as a "natural dividend."
