The resulting FRD experience, expressed as a total of seventeen case studies, captures a wide range of environmental conditions extending across Mongolia, demonstrating economic affordability, social acceptability and ecological viability. Such experiences can inform all stakeholders about alternative and cost-effective environmental rehabilitation approaches that have been applied and adapted to the variety of ecological conditions across the country. This case study handbook can be used in conjunction with the Frugal Rehabilitation Methodology (FRM) Field Handbook and will serve to inform and guide the development of ASM NGO-led rehabilitation partnerships with local government, so scaling-up and replicating priority frugal rehabilitation best practices throughout the country.
