 Hi, I'm Lisa Mandel. I'm a senior scientist with a natural capital project, where I work on incorporating ecosystem services into infrastructure development decisions and development planning in general. I'm going to be talking about our decision support software tool called Opal, which stands for Offset Portfolio Analyzer and Locator. Opal actually grew out of work that we started in Colombia in Latin America. In 2012, Colombia passed a law that requires development projects account for their impacts to terrestrial biodiversity and then offset those losses through protection of natural ecosystems or restoration. They're in the process of adding requirements for marine and freshwater biodiversity as well as ecosystem services. The Nature Conservancy in Latin America and in Colombia led the development of the 2012 compensation policy and is continuing to lead development of the policy in addition of the freshwater and marine and ecosystem services components. And they found that despite this policy, it's still been a challenge translating the laws and policies in Colombia into application and practice on the ground. So the National Licensing Authority in Colombia and the Ministry of Environment there receive many requests for development permits and have to evaluate these unfairly rapid timelines. They're like many countries around the world, short staffed and don't have the capacity that they would like to devote to this. And so this is where Natural Capital Project got brought in to help provide the tools that can translate that policy into practice and do it in a way that's science-based and also effective given the time frame and the resources available. This is how we developed the tool, which in Colombia is called MAFE-T. MAFE-T allows users either in the Ministry of Environment or the National Licensing Authority in Colombia or consultants who are hired by developers to put forward applications for development projects to implement the policy in their impact assessment and offset selection. OPAL is a generalized version of MAFE-T that can be used anywhere in the world with local inputs and local data to understand what impacts of development projects like roads and mines and other forms of infrastructure might be on biodiversity and ecosystem services and then to assess what mitigation options exist to offset those impacts in a way that accounts for how those impacts affect people and the ecosystem services that they depend on. Like all of the Natural Capital Project's tools, OPAL is free and open source and downloadable from our website at naturalcapitalproject.org.
