Biodiversity
Enhancing climate change mitigation in protected areasBackgroundProtected areas (PAs) cover roughly 15–17% of the Earth’s land surface and contain a large share of remaining intact ecosystems, many of which store high densities of carbon. With global terrestrial ecosystems absorbing about 3 GtC yr⁻¹, understanding how much of this sink is associated with PAs is important for integrating biodiversity and climate strategies. However, evidence on PA effectiveness for carbon protection, across thousands of sites and multiple biomes, is dispersed and unevenly synthesized. Open access copy available |
Don’t judge species on their originsBackgroundThis commentary suggests that the long-standing “native versus non-native species” debate has created a widespread bias in conservation as it encourages the idea that introduced species are inherently harmful, despite limited quantitative evidence supporting broad claims of catastrophic biodiversity loss. As global changes (such as climate change, nitrogen eutrophication, increased urbanization, and other land-use changes) cause ecosystems to be unable to restore to their historical states, categorizing species based on their origin increasingly mismatches ecological reality, influencing policy, funding, and management priorities.

Valuing natural capital and ecosystem services toward the goals of efficiency, fairness, and sustainabilityBackgroundNatural capital (NC) and ecosystem services (ES) are fundamental to sustaining human life, but valuing them requires a whole-system understanding of the interdependencies between humans and nature. Conventional economic valuation, based solely on individual willingness-to-pay, is too narrow for this complex task. Available with subscription or purchase |
Diverse values of nature for sustainabilityBackgroundDespite 25 years of progress in valuing ecosystem services, a global biodiversity crisis persists, underpinned by a "values crisis." Current policies and decisions often prioritize a narrow subset of market-based instrumental values, ignoring the diverse ways people relate to and benefit from nature. This paper, based on the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Values Assessment, synthesizes over 50,000 sources to address this gap.

Carbon dynamics with stand structure and species diversity in the Hindu Kush Himalaya ranges of PakistanBackgroundGlobal climate change and biodiversity loss underscore the importance of forests in climate change mitigation and ecosystem stability, as highlighted by UN Sustainable Development Goals 13 and 15. The Hindu Kush Himalaya region in Pakistan is a critical biodiversity hotspot and a significant carbon reservoir. However, the relationships among forest structure, species diversity, and carbon storage in this region remain poorly understood, particularly under current management exclusions and anthropogenic pressures.

The drivers and impacts of Amazon forest degradationBackgroundThis research examines the growing threat of forest degradation across the Amazon, a region critical to global carbon balance and biodiversity. Beyond deforestation, widespread disturbances such as fire, edge effects, selective logging, and extreme drought have emerged as major causes of ecological and social disruption. These human-driven stressors, intensified by climate change, now affect approximately 2.5 million km²—around 38% of remaining Amazon forests—posing risks comparable to deforestation itself.
