The applicants need to propose to set up project(s) that will promote nature-based solutions products, services and business models encompassing sustainable forest management, or watershed management, or land conservation, or waste management to address pressing climate change adaptation challenges and also promoting green initiatives through local partnerships, behavioral change campaigns, new distribution models, etc. Hence, the private sector companies are being challenged to set up projects that shall front-load the necessity for job creation and livelihood improvements as the green solution is articulated along the triple-A paradigm of Affordability, Accessibility, and Acceptability among the targeted households who will benefit from the project as suppliers or consumers of the product/service/technology/business model to be promoted under the project.
