Don't dilute the term Nature Positive

An aspirational approach to planetary futures

Prevailing frameworks to address planetary environmental challenges tend to focus on setting goals, targets, or boundaries to limit human harm to ecosystems or species. Here we propose an aspirational approach aimed at empowering people to shape a better future for all of life on Earth. We do this by building on the human development approach and its supporting metrics, especially the Human Development Index (HDI), a broadly influential framework that has contributed to decades of human progress by measuring and promoting people's capabilities to lead the lives that they value. Rather than assessing the state or dynamics of the biosphere, we propose the Nature Relationship Index (NRI), which would focus on measuring the progress of nations towards delivering mutually beneficial relationships among people and the rest of the living world in terms that people widely understand and value. Through an open-ended process informed by expert consultation, international concept testing and indicator development, the NRI could help to incentivize progress towards a world in which humanity thrives together with the rest of life on Earth. We explore the challenges and opportunities of developing a robust NRI and invite broader participation to facilitate this development in collaboration with the United Nations Development Programme Human Development Report.

What is a unit of nature? Measurement challenges in the emerging biodiversity credit market

Bending the curve of biodiversity loss requires the business and financial sectors to disclose and reduce their biodiversity impacts and help fund nature recovery. This has sparked interest in developing generalizable, standardized measurements of biodiversity-essentially a 'unit of nature'. We examine how such units are defined in the rapidly growing voluntary biodiversity credits market and present a framework exploring how biodiversity is quantified, how delivery of positive outcomes is detected and attributed to the investment and how the number of credits issued is adjusted to account for uncertainties. We demonstrate that there are deep uncertainties throughout the process and question if the benefits of biodiversity credits, and other efforts to abstract nature to a single unit, outweigh the harms. Credits can only be positive for biodiversity if they are used with unprecedentedly strict regulation that ensures businesses mostly avoid negative impacts and if they are purchased to quantify positive contributions rather than as direct offsets. While there may be a role for markets in attracting conservation funding, they will only ever be part of the solution, especially for the many aspects of nature that cannot be reduced to a unit.

An introduction to key ecological concepts, financial opportunities, and risks underpinning aspirations for nature positive

Global biodiversity is in decline, and businesses and society are being required to urgently create new operating models to ameliorate the crisis. Among the strategies proposed to do this, implementing the concept of nature positive has captured worldwide attention. Critical to its success will be effective collaboration between ecologists and businesspeople, driven by a shared understanding of key nature positive terminology, concepts, and risks. To this end, we introduce three core aspects: the ecological concepts in the definition of nature positive (health, abundance, diversity, and resilience), a typology of financial instruments that may be applied to achieving nature positive, and an overview of risks to biodiversity and society. The pivotal findings include that ecological complexity and uncertainty belie the simplicity of the definition of nature positive and that managing risk requires embedding aspirations into existing and emerging biodiversity conservation and restoration science and policy. Although it is challenging, nature positive deserves pursuit.

A nature-positive future with biological invasions: theory, decision support and research needs

In 2050, most areas of biodiversity significance will be heavily influenced by multiple drivers of environmental change. This includes overlap with the introduced ranges of many alien species that negatively impact biodiversity. With the decline in biodiversity and increase in all forms of global change, the need to envision the desired qualities of natural systems in the Anthropocene is growing, as is the need to actively maintain their natural values. Here, we draw on community ecology and invasion biology to (i) better understand trajectories of change in communities with a mix of native and alien populations, and (ii) to frame approaches to the stewardship of these mixed-species communities. We provide a set of premises and actions upon which a nature-positive future with biological invasions (NPF-BI) could be based, and a decision framework for dealing with uncertain species movements under climate change. A series of alternative management approaches become apparent when framed by scale-sensitive, spatially explicit, context relevant and risk-consequence considerations. Evidence of the properties of mixed-species communities together with predictive frameworks for the relative importance of the ecological processes at play provide actionable pathways to a NPF in which the reality of mixed-species communities are accommodated and managed. This article is part of the theme issue 'Ecological novelty and planetary stewardship: biodiversity dynamics in a transforming biosphere'.

Translating genomic advances into biodiversity conservation

A key action of the new Global Biodiversity Framework is the maintenance of genetic diversity in all species to safeguard their adaptive potential. To achieve this goal, a translational mindset, which aims to convert results of basic research into direct practical benefits, needs to be applied to biodiversity conservation. Despite much discussion on the value of genomics to conservation, a disconnect between those generating genomic resources and those applying it to biodiversity management remains. As global efforts to generate reference genomes for non-model species increase, investment into practical biodiversity applications is critically important. Applications such as understanding population and multispecies diversity and longitudinal monitoring need support alongside education for policymakers on integrating the data into evidence-based decisions. Without such investment, the opportunity to revolutionize global biodiversity conservation using genomics will not be fully realized.
