Ecosystem Management: The Need to Adopt a Different Approach Under a Changing Climate

This research paper argues for a fundamental shift in how ecosystems are valued and managed to address the combined threats of climate change and unsustainable resource demands. The authors contend that current economic models treat ecosystems as undervalued commodities, leading to market failures and degradation. They propose an 'ecosystems approach' that integrates ecosystem-based mitigation and adaptation into the heart of political and economic decision-making to ensure climate stability and the continued delivery of essential services.

• Climate stabilisation requires a three-way balance between the capacity of global ecosystems to absorb greenhouse gases, natural emissions from ecosystems, and human-induced emissions. Current policy is overly focused on human-based emissions, which the authors argue is insufficient for achieving stability.
• Global ecosystems currently absorb approximately half of anthropogenic CO2 emissions, with oceans accounting for about 24% and land about 30%. However, this absorptive capacity is declining by roughly 1% per decade and may accelerate due to human impacts and climate change.
• The authors describe ecosystems as a "win-win-win" link because they simultaneously support climate mitigation (through carbon sequestration), climate adaptation (by providing a foundation for societal resilience), and long-term sustainability. This approach provides social, economic, and environmental benefits, including food and water security and public health.
• An ecosystem management approach acts as a "safety net" against potential failures in human-led emission reduction efforts. Because the resilience of ecosystems to climate change is uncertain, the authors advocate for the precautionary principle to ensure ecosystems are protected as the primary mechanism for climate regulation.
• Current economic models have resulted in a significant market failure where the resources supporting human society are degraded because ecosystems are treated as undervalued commodities. The authors argue that market-driven mechanisms alone may be insufficient and that a fundamental societal shift in valuing biodiversity is required.
• The paper proposes four complementary strategies to prioritize ecosystem protection: securing political commitment to raise the profile of ecosystems, providing investment (specifically via a Global Climate Change Fund), introducing incentives for land and water protection, and improving information sharing between science, policy, and different nations.
