Recent findings from the Natural History Museum in London highlight a troubling trend – biodiversity is declining more rapidly within protected areas than outside them. This revelation raises critical questions about the efficacy of current conservation strategies, suggesting that merely designating areas as protected does not guarantee improved biodiversity outcomes. This has prompted calls for a reevaluation of conservation policies and practices to ensure that they genuinely protect ecosystems.
About Biodiversity Intactness Index (BII)
The Biodiversity Intactness Index (BII) serves as important metric for assessing the health of ecosystems. It estimates the proportion of natural biodiversity remaining in a region. Between 2000 and 2020, the BII has shown a global decline of 1.88 percentage points. This measure is vital for understanding the overall state of biodiversity and informs conservation efforts. The study also examined critical biodiversity areas (CBAs), where 22% are currently protected, yet these areas are experiencing alarming declines in biodiversity.
Analysis of Protected vs. Unprotected Areas
The research revealed that biodiversity within unprotected critical areas declined by an average of 1.9 percentage points, while protected areas fared worse, with a decline of 2.1 percentage points. This counterintuitive result suggests that current conservation strategies are insufficient. Many protected areas focus on specific species rather than the broader ecosystem, leading to inadequate protection of biodiversity as a whole.
Factors Contributing to Biodiversity Loss
Several factors contribute to the decline of biodiversity in protected areas. Firstly, many of these areas were already degraded before protection was enacted, limiting their potential for recovery. Additionally, activities such as oil, gas, and mining concessions pose threats. For instance, over 65% of the Conkouati-Douli National Park in the Republic of the Congo is under such concessions, jeopardising one of the most biodiverse regions.
The Role of Climate Change
Climate change exacerbates the challenges faced by protected areas. Increased frequency and intensity of droughts and wildfires have devastating impacts. The 2019 wildfires in Australia, which ravaged several national parks, exemplify how even strictly protected areas are vulnerable. This puts stress on the need for a multifaceted approach to conservation that includes climate resilience.
Policy Implications and Future Directions
The study calls for a shift in conservation strategies. Policymakers must recognise that simply increasing protected area coverage is insufficient. The focus should be on effective management and conservation of existing areas, ensuring they are designed to protect entire ecosystems rather than select species. The commitment to the 30×30 initiative, which aims to conserve 30% of the world’s lands and oceans by 2030, should be upheld with a more robust strategy that prioritises ecosystem health.
