Other Effective Area-Based Conservation Measures, Biodiversity Stewardship and Statutory Intervention – A South African Perspective

Area-based approaches are a central component of global efforts to conserve biodiversity. While the focus of many countries has been mainly on protected areas, other effective area-based conservation measures (OECMS) have been accorded global recognition in the past decade as a vital complementary approach to protected areas. This recognition has been reemphasised in the Kunming-Montreal Global Biodiversity Framework adopted by parties to the Convention on Biological Diversity in December 2022, with its Target 3 ratchetting up area-based coverage targets to 30 per cent by 2030. A growing focus and reliance on OECMs to contribute towards achieving this target is anticipated. The international community has in the past few years introduced some guidance to identify, secure, manage, monitor and verify the anticipated long-term biodiversity conservation outcomes of OECMs. Some commentators have argued for domestic legal intervention to complement this general international guidance. The South African Government has recognised the potential contribution of OECMs towards the achievement of domestic and global area-based biodiversity targets in its National Protected Areas Expansion Strategy (2018) but has alluded to the need for legal intervention to ensure that they achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity. Some domestic commentators have highlighted the strong link between biodiversity stewardship (particularly conservation areas) and OECMs, advocating that these conservation areas should form the priority focus of domestic efforts to identify OECMs. This article scopes this potential link and specifically considers whether the current domestic legal and policy framework applicable to these conservation areas is sufficiently robust to ensure that only appropriate areas are identified as OECMs and that once recognised, they are governed and effectively managed in the long term. It highlights several frailties of the existing framework and drawing from anticipated legal reform in the Western Cape relating to biodiversity stewardship, it proposes a possible model for future national legislation regulating OECMs.

Developing Biodiversity Baselines to Develop and Implement Future Conservation Targets.

With the recent launch of the Kunming-Montreal global biodiversity framework (GBF), and the associated monitoring framework, understanding the framework and data needed to support it is crucial. Unfortunately, whilst the monitoring framework was meant to provide key data to monitor progress towards goals and targets, most indicators are too unclear for detection or marking progress. The most common datasets for this task, such as the IUCN redlist of species, have major spatial inaccuracies, and lack the temporal resolution to track progress, whilst point-based datasets lack data from many regions, in addition to species coverage. Utilising existing data will require the careful use of existing data, such as the use of inventories and projecting richness patterns, or filling data gaps before developing species-level models and assessments. As high-resolution data fall outside the scope of explicit indicators within the monitoring framework, using essential biodiversity variables within GEOBON (which are noted in the prelude of the monitoring framework) as a vehicle for data aggregation provides a mechanism for collating the necessary high-resolution data. Ultimately developing effective targets for conservation will require better species data, for which National Biodiversity Strategic Action Plans (NBSAPs) and novel mechanisms for data mobilisation will be necessary. Furthermore, capitalising on climate targets and climate biodiversity synergies within the GBF provides an additional means for developing meaningful targets, trying to develop urgently needed data to monitor biodiversity trends, prioritising meaningful tasks, and tracking our progress towards biodiversity targets.

Heavy reliance on private finance alone will not deliver conservation goals.

The Kunming-Montreal Global Biodiversity Framework envisages an increasing reliance on large-scale private finance to fund biodiversity targets. We warn that this may pose contradictions in delivering conservation outcomes and propose a critical ongoing role for direct public funding of conservation and public oversight of private nature-related financial mechanisms.

Forest protection in the EU's renewable energy directive and nature conservation legislation in light of the climate and biodiversity crisis – Identifying legal shortcomings and solutions

Forests ecosystems have an indispensable value for global climate and biodiversity protection. Alongside manifold other functions, forests ecosystems are important suppliers of raw materials in a post-fossil world. However, without effective legal restrictions, the increasing demand for woody biomass for energy production counteracts effective forest conservation in Europe and third countries. Against this background, this article assesses the governance effects of the EU Renewable Energy Directive and the EU nature conservation legislation, particularly the directives forming the Natura 2000 network, and the proposed Nature Restoration Law. To this end, a qualitative governance analysis is applied. In a first step the sustainability criteria of the Renewable Energy Directive are assessed regarding intra- and extraterritorial effects and their ability to avoid typical governance problems. Thereafter, to investigate achievable steering effects, EU nature conservation legislation is analysed. The legal analysis shows that typical governance problems reoccur, rendering the effectivity of the assessed command-and-control regulations too low to protect forest ecosystems in line with international climate and biodiversity targets. Only the proposed Nature Restoration Law might unfold a larger legal steering effect in the future, if a number of shortcomings are addressed. However, as typical governance problems can never be fully avoided, it remains necessary to reduce pressures on forest ecosystems by additional market-based instruments These instruments should be applied on European policy level to induce sufficiency in the private transport sector and in relation to consumption patterns for energy and food.

A framework for the detection and attribution of biodiversity change.

The causes of biodiversity change are of great scientific interest and central to policy efforts aimed at meeting biodiversity targets. Changes in species diversity and high rates of compositional turnover have been reported worldwide. In many cases, trends in biodiversity are detected, but these trends are rarely causally attributed to possible drivers. A formal framework and guidelines for the detection and attribution of biodiversity change is needed. We propose an inferential framework to guide detection and attribution analyses, which identifies five steps-causal modelling, observation, estimation, detection and attribution-for robust attribution. This workflow provides evidence of biodiversity change in relation to hypothesized impacts of multiple potential drivers and can eliminate putative drivers from contention. The framework encourages a formal and reproducible statement of confidence about the role of drivers after robust methods for trend detection and attribution have been deployed. Confidence in trend attribution requires that data and analyses used in all steps of the framework follow best practices reducing uncertainty at each step. We illustrate these steps with examples. This framework could strengthen the bridge between biodiversity science and policy and support effective actions to halt biodiversity loss and the impacts this has on ecosystems. This article is part of the theme issue 'Detecting and attributing the causes of biodiversity change: needs, gaps and solutions'.

Protected area planning to conserve biodiversity in an uncertain future.

Protected areas are a key instrument for conservation. Despite this, they are vulnerable to risks associated with weak governance, land-use intensification, and climate change. We used a novel hierarchical optimization approach to identify priority areas for expanding the global protected area system that explicitly accounted for such risks while maximizing protection of all known terrestrial vertebrate species. To incorporate risk categories, we built on the minimum set problem, where the objective is to reach species distribution protection targets while accounting for 1 constraint, such as land cost or area. We expanded this approach to include multiple objectives accounting for risk in the problem formulation by treating each risk layer as a separate objective in the problem formulation. Reducing exposure to these risks required expanding the area of the global protected area system by 1.6% while still meeting conservation targets. Incorporating risks from weak governance drove the greatest changes in spatial priorities for protection, and incorporating risks from climate change required the largest increase (2.52%) in global protected area. Conserving wide-ranging species required countries with relatively strong governance to protect more land when they bordered nations with comparatively weak governance. Our results underscore the need for cross-jurisdictional coordination and demonstrate how risk can be efficiently incorporated into conservation planning.

How Indonesian marine protected areas (MPAs) are doing: A management performance-based evaluation

According to the Convention on Biological Diversity (CBD) post-2020 global biodiversity framework, marine conservation activities aiming solely at area coverage are insufficient; thus, a persistent effort is required to establish effective marine protected areas (MPAs). Despite the fact that the number of MPAs has expanded dramatically over time, their management effectiveness still needs to improve, particularly in developing nations. Hence, this study was conducted to quantitatively and qualitatively assess the current state of Indonesian MPAs in meeting the Aichi targets. The government's investigative reports served as the foundation for the quantitative research, while a government-led interview-based survey conducted across 61 Indonesian locations served as the basis for the qualitative study. The findings showed that although the present Indonesian MPAs were at the stage of meeting the national target of 10 % coverage, it was anticipated that they would fall short of the new 30 % worldwide target by 2030. Although 61 % and 39 % of the research sites were managed at a minimal and optimal level, respectively, the evaluation of the management effectiveness of the MPAs in Indonesia indicates that none of the sites were sustainably managed. Lack of funding due to a need for infrastructure, facilities, and human resources was the main problem impeding management effectiveness. Based on the study's findings, it is recommended that the nation's biodiversity targets be designed to focus more on the development and oversight of the current MPA management and provide a perceptive policy response concerning the post-2020 global biodiversity framework.

Integrating biodiversity and ecosystem services to identify ecological priorities for an ecologically fragile city in China

AbstractA high rate of urbanization comes with high environmental costs, leading to reductions in biodiversity and ecosystem services (BES). How to maximize the efficiency and representation of BES in cities is of utmost urgency. However, in the process of spatial prioritization identification, it remains unclear whether a preference for ecosystem services (ES) promotes or detracts from biodiversity. In this study, a Marxan‐based spatial conservation prioritization framework is provided to achieve a win–win situation for ES provision and biodiversity protection. Using Hohhot city, China as a study case, it sets up different weighting scenarios with species and five ES to determine the optimal protected area network for each possible combination. At the same time, it tests the conservation costs, protected features, and spatial overlap of different scenarios with existing protected areas to quantify their conservation efficiency. We found that (1) closed deciduous broadleaved forests, closed evergreen needle‐leaved forests, and deciduous shrublands could support both high biodiversity and abundant ES at altitudes of 1600–2000 m. (2) Although a positive association is found between ES and biodiversity, there is some spatial variation. The geographical overlap rate with biodiversity prioritization was only 29.72% when only ES were considered. (3) Conservation of ecological hotspots by increasing the weight of ES can reduce conservation expenses by 0.69%–20.32% compared to meeting solely biodiversity targets. Our analyses highlight the need for an appropriate weighting of ES in decisions seeking to identify protected areas. This study provides methodological support for the integration of ES and biodiversity, facilitating more comprehensive conservation planning decisions.

Carbon-biodiversity relationships in a highly diverse subtropical forest.

Carbon-focused climate mitigation strategies are becoming increasingly important in forests. However, with ongoing biodiversity declines we require better knowledge of how much such strategies account for biodiversity. We particularly lack information across multiple trophic levels and on established forests, where the interplay between carbon stocks, stand age, and tree diversity might influence carbon-biodiversity relationships. Using a large dataset (>4600 heterotrophic species of 23 taxonomic groups) from secondary, subtropical forests, we tested how multitrophic diversity and diversity within trophic groups relate to aboveground, belowground, and total carbon stocks at different levels of tree species richness and stand age. Our study revealed that aboveground carbon, the key component of climate-based management, was largely unrelated to multitrophic diversity. By contrast, total carbon stocks-that is, including belowground carbon-emerged as a significant predictor of multitrophic diversity. Relationships were nonlinear and strongest for lower trophic levels, but nonsignificant for higher trophic level diversity. Tree species richness and stand age moderated these relationships, suggesting long-term regeneration of forests may be particularly effective in reconciling carbon and biodiversity targets. Our findings highlight that biodiversity benefits of climate-oriented management need to be evaluated carefully, and only maximizing aboveground carbon may fail to account for biodiversity conservation requirements.

Detecting low fragmented sites surrounding European protected areas – Implications for expansion of the Natura 2000 network

EU member states have set an ambitious goal of establishing additional protected areas (PAs) preserving 30 % of terrestrial land by 2030, specifying that additions should be of high ecological quality. A targeted selection of existing PA expansions into surroundings marginally fragmented by human infrastructure, may be an efficacious strategy to secure high ecological quality by maximizing PA area, accommodating species movement, and boosting climate change resilience. We used high-resolution data on effective mesh density, a metric measuring landscape fragmentation, in the vicinity of Natura 2000 PAs (N2k) to assess their potential for expansion. Our results show that contrary to most of Central Europe, mountainous and remote territories exhibit the lowest degree of fragmentation in N2k surroundings. Fragmentation in N2k surroundings is highly correlated with national population density, while economic wealth, measured by GDP per capita, plays a minor role. To address the long-standing dilemma of where scarce economic resources in nature conservation do the most-good, we conducted a country-level comparison between fragmentation in N2k surroundings and national expenditures on nature conservation relative to N2k area. Our results show a vast incongruity in resource availability for nature conservation among EU countries. Eastern European states, especially Romania, host underfunded N2k PAs while holding the highest potential for expanding N2k PAs into low fragmented lands. If protecting low fragmented lands is accepted as an efficacious strategy to meet EU biodiversity targets our results could be used to formulate pragmatic conservation decisions, while also ensuring high ecological quality of PA additions under climate change.

Monitoring the impacts of a mega-dam on Amazonian understorey herbs

Mega-dams have drastically altered the pulse of natural flooding in rivers of the Amazon, negatively affecting the biodiversity of different forest ecosystems. This study aimed to investigate the impacts of the Jirau dam on herbaceous assemblages, a relatively little studied biodiversity component. To accomplish this, we surveyed understorey herbs in 22 permanent plots (375 m2 each) between 2012 and 2019, before and after filling of the Jirau dam, and also measured a set of environmental predictors. Sampling comprised 178 morphospecies and 43,335 individuals. We found that species compositions in the pre-dam period differed in each of the sampled habitats (terra firme, transitional forest, várzea, and campinarana), and that such differences were mostly correlated with sum of bases, topography, C/N ratio, silt and pH. Environmental associations differed among three major groups of herbs (Ferns, Poales and Zingiberales). During the post-dam period, flooded plots showed high rates of mortality and recruitment close to 100 % and a sharp decline in species richness while non-flooded plots showed relative stability for these parameters. The number of flooded days and habitat type were strong predictors of mortality and recruitment rates. A combination of canopy opening driven by tree mortality and seasonal flooding after filling of the Jirau reservoir altered herb species composition in flooded plots, favouring the recruitment of Poales. Overall, herbaceous plants showed higher sensitivity to flooding caused by the Jirau dam when compared to trees sampled in the same site, reinforcing their potential as biodiversity targets for environmental assessments.

Leveraging private lands to meet 2030 biodiversity targets in the United States

AbstractCoincident with international movements to protect 30% of land and sea over the next decade (“30×30”), the United States has committed to more than doubling its current protected land area by 2030. While publicly owned and managed protected areas have been the cornerstone of area‐based conservation over the past century, such lands are costly to establish and have limited capacity to protect areas of the highest value for biodiversity conservation and climate change mitigation. Here we examine the current and potential contributions of private land for reaching 30×30 conservation targets at both federal and state scales in the United States. We find that compared to publicly owned and managed protected lands, protected private lands (conservation easements) are more often in areas designated as high conservation priority, hold significantly higher mean species richness, and sequester more vulnerable land‐based carbon per unit area. These and related findings highlight the necessity of mechanisms that engage private landholders in enduring conservation partnerships.

“Rights for Life” scenario to reach biodiversity targets and social equity for indigenous peoples and local communities

Scenarios are a powerful way in which the scientific community can inform future policies for transformative change. Forthcoming scenario work holds promise for the Nature Futures Framework, which through the concept of relational values, seeks to recognize a multiplicity of value positions on human-environment relations, including those of Indigenous Peoples and Local Communities (IPLCs). The objective of this Perspective paper is to propose a novel scenario skeleton titled “Rights for Life”, which holds promise to achieve ambitious biodiversity targets in a socially-equitable ways by focusing on the Nature's and IPLCs' rights. We demonstrate, through the case of Arctic reindeer (Rangifer tarandus tarandus) herding, that the “Rights for Life” scenario seems to deliver better social equity outcomes than the recently proposed “Half Earth” and “Sharing the Planet” scenarios that have been designed to achieve ambitious conservation and biodiversity targets. The “Rights for Life” scenario is particularly fit for sparsely-populated indigenous homelands and rural regions where local communities depend on culturally important nature-based livelihoods for their well-being. We recommend that future scenarios targeting human-environment relations should not only consider non-western and relational value perspectives, but also recognize the importance of Nature's and IPLCs' rights for ensuring transformative change for equity and the environment. Clear recognition of such rights can function as a basis for new regulations, market-based governance instruments, policies, and participatory governance instruments ensuring that violation of Nature's and IPLCs' rights by societal developments is recognized, avoided, minimized, or at least compensated for.

Pathways to achieving nature-positive and carbon–neutral land use and food systems in Wales

Land use and its management can play a vital role in carbon sequestration, but trade-offs may exist with other objectives including food security and nature recovery. Using an integrated model (the FABLE calculator), four pathways, co-created with colleagues at the Welsh Government, towards achieving climate and biodiversity targets in Wales were explored: status quo, improvements on current trends, land sparing and land sharing. We found that continuing as usual will not be sufficient to meet Wales’s climate and biodiversity targets. In contrast, the land use and agricultural sector became a net carbon sink in both the land sparing and land sharing pathways, through high afforestation targets, peatland restoration, reducing food waste and moving towards a healthier diet. Whilst both pathways released land for biodiversity, the gains were greater in the land sharing pathway, which was also less dependent on optimistic assumptions concerning productivity improvements. The results demonstrate that alternative approaches to achieving nature-positive and carbon–neutral land use and food systems may be possible, but they come with stringent and transformative requirements for policy changes, with an integrated approach necessary to maximise benefits for climate, food and nature.

Conservation at a crossroads: governing by global targets, innovative financing, and techno-optimism or radical reform?

Biodiversity conservation is at a crossroads. A number of trends are converging with the potential to transform our understanding of nature and how we conserve it. First, conservation policy makers are advocating increasingly ambitious global biodiversity targets, such as the agreement to protect 30% of terrestrial, inland water, and of coast and marine areas by 2030 made at the December 2022 Conference of the Parties to the Convention on Biological Diversity. Second, recognizing that governments do not have sufficient resources to reach these ambitious targets, they are turning to private finance and innovative financing mechanisms for help. Third, technological advances are enabling new ways of surveilling people, species, and ecosystems, measuring conservation outcomes, and targeting funding. Finally, long-standing concerns over the alienation of Indigenous Peoples and local communities from land and resources, and the colonial legacy of conservation, have been amplified by widespread contemporary awareness of racism more generally. Nascent critiques of conservation are incorporating but also moving beyond calls for participatory or rights-based approaches to conservation to push for the complete decolonization of conservation, alternatives to capitalist approaches to conservation, and other radical reforms. Collectively, these shifts are both reinforcing traditional conservation practice and power relationships and opening up space to expand understandings of collaborative management, environmental caretaking, and sustainable livelihoods and dramatically reform conservation. In this article, we draw on decades of research studying conservation governance in sites that range from villages to international meetings in order to examine this critical historical moment in conservation politics. We argue that conservation is at an ontological and epistemic moment during which the meaning of biodiversity, how to know it, how to conserve it, and who should conserve it is being fundamentally transformed. As transnational movements seek to transform our political economic system and to decolonize conservation, the consolidation of elite power among actors in finance, technology, governments, and big nongovernmental organizations abstracts conservation from localized contexts, drawing attention away from ensuring effective conservation on the ground and failing to challenge the root causes of biodiversity loss. Thus, continued vigilance is needed to keep equity, rights, justice, and livelihoods at the forefront of conservation.

Policies and socioenvironmental dynamics for ecosystem management

The continuous loss of biodiversity has extended the Convention on Biological Diversity's target towards safeguarding 30% of the planet by 2030 with some form of protected area management. This is a challenge, considering the poor compliance of the Aichi Biodiversity Targets reported in several assessments, and that 37% of the remaining unprotected natural areas are inhabited by indigenous and local communities. Modern conservation policies tend to convert areas destined for protection into complex socioecological landscapes, so it is critical to develop policies capable of establishing long-term harmonious relations between local societies and their environments. Despite the fundamental importance of defining this interrelation, methodologies for evaluating it are still unclear. We propose a method for assessing the outcome of policies in socioenvironmental practices based on a historical-political ecology analysis of a region, the construction of socioenvironmental scenarios, and comparing populations scattered through the study area. Each “scenario” is a relation between nature and society after a shift in public policies. Conservation scientists, environmental managers, and policymakers can use this methodology to assess old policies, design new ones, or map the socioenvironmental dynamics in their area of interest. Here, we detail this approach and illustrate its application in the coastal wetlands of Mexico. The method can be outlined as follows:•Deduce socioenvironmental epochs for a region by analysing its historical political ecology.•Analyse the socioenvironmental dynamics in selected case studies scattered through the region.•Use the resulting scenarios as conceptual bridges between internal policies and current socioenvironmental dynamics.

An evidence‐base for developing ambitious yet realistic national biodiversity targets

AbstractBiodiversity targets are a key tool, used at a global and national policy level, to align biodiversity goals, promote conservation action, and recover nature. Yet most biodiversity targets are not met. In England, the government has committed to legally‐binding targets to halt and recover the decline in species abundance by 2030 and 2042. We present evidence from recent population trends of 670 terrestrial animal species (for which abundance time series are available) as a species abundance indicator, together with a synthesis of case studies on species recovery, to assess the degree to which these targets are achievable. The case studies demonstrate that recovery is possible through a range of approaches. The indicator demonstrates that theoretically targets can be achieved by addressing severe declines in a relatively small number of species, as well as creating smaller benefits for many species through landscape‐scale interventions. The fact that multiple pathways exist to achieve the species abundance targets in England presents choices but also raises the possibility that targets might be reached with perverse consequences. We demonstrate that evidence on achievability is a necessary but not sufficient condition for determining what is required to deliver conservation outcomes and restore biodiversity.

Towards forward-looking nature governance to meet conservation goals of Natura 2000 sites in the European Union: experts’ perspectives

AbstractAs Natura 2000 missed challenges of halting biodiversity decline, its’ management is being affected by factors of ecological, political, and economic character. To address the shortcomings revealed during the Fitness Check and to facilitate meeting the EU’s biodiversity targets, the European Commission developed an “Action Plan for Nature, People and the Economy” prioritizing areas for improvement. However, mixed views still exist on the Natura 2000 governance; it is not certain that Action Plan would address existing drawbacks. The aim of the research was to identify divergent and convergent experts’ attitudes towards biodiversity conservation in Europe, with a focus on forward-looking environmental governance and policy-informing perspective. Participants representing multiple disciplines and professional backgrounds related to planning, governance, or management of Natura 2000 sites provided a comprehensive overview on the topic and address-related challenges. Based on the results of a Delphi survey, we established a framework for illuminating the spaces of disjunction in experts’ views towards Natura 2000 conservation. We distinguished three main divergence areas in views towards future network operation: (1) raising public awareness of environmental problems in the network, (2) the role of the European Commission in building political ownership of Natura 2000 sites among landholders, and (3) funding of Natura 2000. Then, based on revealed dichotomies, we return with drawing a roadmap for promoting more consensual outcomes. The results should help enable the practical management of conflicting views and the effective engagement of future biodiversity conservation strategies in Europe and beyond.

Action plans for species conservation are an important tool to meet global and national biodiversity targets – A study case in Brazil

National action plans for the conservation of threatened fauna species (PANs) are instruments to promote the implementation of global biodiversity targets on a national scale. In Brazil, 74.8% of threatened animal species were covered with PANs by the end of 2019. In this study we evaluate the contribution of these PANs as tools for species conservation and for attaining Aichi targets. Between 2004 and 2019, 38 PANs were concluded, and 42.76% of the 2,044 actions, included in the PANs, were achieved. These actions promoted a series of conservation measures that contributed to 10 of the 20 Aichi targets, resulting in direct benefits for the target species.

Mainstreaming biodiversity in business decisions: Taking stock of tools and gaps

Most businesses depend on biodiversity, either directly, indirectly as ecosystem services, or through their supply chains. In negatively impacting biodiversity, businesses risk losing essential resources and services. As a result, it is important for the private sector to demonstrate strong and improved performance on biodiversity.This paper reviews and compares tools and approaches that help businesses measure their performance on biodiversity issues. Through a literature review and interviews of tool developers, we assess how tools are constructed, how they measure biodiversity performance, how and where they are being used by different businesses and how they contribute to achieving international targets for biodiversity. We found that tools perform a range of functions and are mostly applied at product, site, and supply chain level. Further efforts are needed to align tools with global biodiversity goals. Key knowledge gaps remain to better capture dependence on biodiversity and spatial spillover effects.
