To attract foreign direct investment in sustainable tourism in Madagascar, several risks must be addressed including regulatory hurdles, economic instability, and government unreliability issues like corruption. The World Bank's Private Sector Window and public-private partnerships can help reduce investment risks in tourism projects. A "cascade approach" to sustainable infrastructure finance moving from commercial to public and concessional resources can mobilize capital for viable projects. Guarantees from the Madagascar government can also help attract investment by reducing risks. Green bonds and catastrophe bonds are suitable financial instruments to promote environmentally friendly and climate-resilient tourism development.
