Abstract

Our recently published paper highlights the Earthwise Framework, an open science endeavor that can be implemented via a variety of software tools and languages, has several frontiers for further research and development, and shows promise in finding a better way to meet both the needs of humans and the needs of biodiversity. At its core, it is designed to address the disconnect between systematic conservation planning and actual on-the-ground implementation. This disconnect is especially important to resolve now that the 30x30 initiative (conserving 30% of the oceans and lands by 2030) is endorsed by over 100 countries worldwide. The Earthwise Framework is a flexible and customizable spatial decision support system (SDSS) architecture and governance process to address the challenges of this planning-implementation disconnect.

To apply the analytic framework, start with a transparent multi-criteria spatial overlay and put that into an iterative allocation algorithm for pursuing an optimal portfolio of sites (e.g. 30% of a planning region). This portfolio is much better for biodiversity than simply the top 30% of the region using the spatial overlay. For example, it is much more connected, and better conserves habitat diversity. Why not just use existing optimization modeling like Marxan or Zonation? Because this one is more transparent and easier to understand. It is therefore better for engaging people in the model development and use, which leads to better buy-in and implementation. Utilizing case study experience from regions within California, South Africa, and British Columbia, we outline the framework, and illustrate key tenants.
