The Wildlife Economy Investment Index (WEII) is a comprehensive framework that centers on the concept of the wildlife economy, which involves the utilization of indigenous wildlife, including both flora and fauna from marine and terrestrial ecosystems, as an economic asset. This approach aims to create value while also aligning with conservation objectives and fostering sustainable growth and economic development. At its core, the WEII comprises two major sub-indices: Wildlife Status and Investment-enabling Environment.

The Wildlife Status Sub-index dives into the size and status of a country's wildlife, encompassing a range of indicators related to wildlife assets, species richness, endemic species, ecological habitats, protected areas, key biodiversity areas covered by protected areas, wildlife management, and the effectiveness of wildlife management. This sub-index provides a deep insight into a nation's wildlife resources and the efforts in place to protect and manage them.

On the other hand, the Investment-enabling Environment Sub-index evaluates the conditions that facilitate investments in the country. It takes into account a broad spectrum of indicators, including ease of doing business, business operations, access to finances, access to markets, corruption, public sector capacity, rule of law, infrastructure, labor market, social inclusion, investment safety, money growth, property rights, and security and stability. This sub-index assesses the overall business environment in the country and how conducive it is to wildlife-based economic activities.

Within each of these sub-indices, there are further categories and sub-categories, allowing for a more detailed and nuanced evaluation of specific aspects. This structured approach enables a multidimensional analysis of a country's wildlife economy, covering various thematic areas and providing valuable insights into its strengths and areas for improvement. With a specified number of indicators for each category and sub-category, the WEII offers a comprehensive overview of the data points considered in the assessment.

Overall, the WEII serves as a powerful tool for governments, researchers, conservationists, and policymakers to understand and enhance a country's performance in the wildlife economy. By providing a comprehensive and structured framework for evaluation, it promotes the adoption of sustainable and inclusive practices in wildlife-based economic activities, ultimately contributing to the preservation of wildlife and the well-being of communities dependent on these resources.
