Safeguarding pollinators and their values to human well-being

Wild and managed pollinators provide a wide range of benefits to society in terms of contributions to food security, farmer and beekeeper livelihoods, social and cultural values, as well as the maintenance of wider biodiversity and ecosystem stability. Pollinators face numerous threats, including changes in land-use and management intensity, climate change, pesticides and genetically modified crops, pollinator management and pathogens, and invasive alien species. There are well-documented declines in some wild and managed pollinators in several regions of the world. However, many effective policy and management responses can be implemented to safeguard pollinators and sustain pollination services.

A typology of Indigenous engagement in Australian environmental management: implications for knowledge integration and social-ecological system sustainability

Indigenous peoples now engage with many decentralized approaches to environmental management that offer opportunities for integration of Indigenous Ecological Knowledge (IEK) and western science to promote cultural diversity in the management of social-ecological system sustainability. Nevertheless, processes of combining IEK with western science are diverse and affected by numerous factors, including the adaptive co-management context, the intrinsic characteristics of the natural resources, and the governance systems. We present a typology of Indigenous engagement in environmental management, derived through comparative analysis of 21 Australian case studies, and consider its implications for the integration of IEK with western science. Sociological and rational choice institutionalism underpin our analytical framework, which differentiates on three axes: (1) power sharing, incorporating decision making, rules definition, resource values and property rights; (2) participation, incorporating participatory processes, organizations engaged, and coordination approaches; (3) intercultural purpose, incorporating purposes of environmental management, Indigenous engagement, Indigenous development and capacity building. Our typology groups engagement into four types: Indigenous governed collaborations; Indigenous-driven co-governance; agency-driven co-governance; and agency governance. From our analysis of manifestations of knowledge integration across the types, we argue that Indigenous governance and Indigenous-driven co-governance provides better prospects for integration of IEK and western science for sustainability of social-ecological systems. Supporting Indigenous governance without, or with only a limited requirement for power sharing with other agencies sustains the distinct Indigenous cultural purposes underpinning IEK, and benefits knowledge integration. We conclude by advocating that the typology be applied to test its general effectiveness in guiding practitioners and researchers to develop robust governance for Indigenous knowledge integration in environmental management.

Participatory scenario planning in place-based social-ecological research: insights and experiences from 23 case studies

Participatory scenario planning (PSP) is an increasingly popular tool in place-based environmental research for evaluating alternative futures of social-ecological systems. Although a range of guidelines on PSP methods are available in the scientific and grey literature, there is a need to reflect on existing practices and their appropriate application for different objectives and contexts at the local scale, as well as on their potential perceived outcomes. We contribute to theoretical and empirical frameworks by analyzing how and why researchers assess social-ecological systems using place-based PSP, hence facilitating the appropriate uptake of such scenario tools in the future. We analyzed 23 PSP case studies conducted by the authors in a wide range of social-ecological settings by exploring seven aspects: (1) the context; (2) the original motivations and objectives; (3) the methodological approach; (4) the process; (5) the content of the scenarios; (6) the outputs of the research; and (7) the monitoring and evaluation of the PSP process. This was complemented by a reflection on strengths and weaknesses of using PSP for the place-based social-ecological research. We conclude that the application of PSP, particularly when tailored to shared objectives between local people and researchers, has enriched environmental management and scientific research through building common understanding and fostering learning about future planning of social-ecological systems. However, PSP still requires greater systematic monitoring and evaluation to assess its impact on the promotion of collective action for transitions to sustainability and the adaptation to global environmental change and its challenges.

Assessing nature’s contributions to people

Recognizing culture, and diverse sources of knowledge, can improve assessments A major challenge today and into the future is to maintain or enhance beneficial contributions of nature to a good quality of life for all people. This is among the key motivations of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), a joint global effort by governments, academia, and civil society to assess and promote knowledge of Earths biodiversity and ecosystems and their contribution to human societies in order to inform policy formulation. One of the more recent key elements of the IPBES conceptual framework (1) is the notion of natures contributions to people (NCP), which builds on the ecosystem service concept popularized by the Millennium Ecosystem Assessment (MA) (2). But as we detail below, NCP as defined and put into practice in IPBES differs from earlier work in several important ways. First, the NCP approach recognizes the central and pervasive role that culture plays in defining all links between people and nature. Second, use of NCP elevates, emphasizes, and operationalizes the role of indigenous and local knowledge in understanding natures contribution to people.

Biodiversity and ecosystem services require IPBES to take novel approach to scenarios

What does the future hold for the world’s ecosystems and benefits that people obtain from them? While the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) has identified the development of scenarios as a key to helping decision makers identify potential impacts of different policy options, it currently lacks a long-term scenario strategy. IPBES will decide how it will approach scenarios at its plenary meeting on 22–28 February 2016, in Kuala Lumpur. IPBES now needs to decide whether it should create new scenarios that better explore ecosystem services and biodiversity dynamics. For IPBES to capture the social-ecological dynamics of biodiversity and ecosystem services, it is essential to engage with the great diversity of local contexts, while also including the global tele-coupling among local places. We present and compare three alternative scenario strategies that IPBES could use and then suggest a bottom-up, cross-scale scenario strategy to improve the policy relevance of future IPBES assessments. We propose five concrete steps as part of an effective, long term scenario development process for IPBES in cooperation with the scientific community.

Ten policies for pollinators

What governments can do to safeguard pollination services Earlier this year, the first global thematic assessment from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) evaluated the state of knowledge about pollinators and pollination (1, 2). It confirmed evidence of large-scale wild pollinator declines in northwest Europe and North America and identified data shortfalls and an urgent need for monitoring elsewhere in the world. With high-level political commitments to support pollinators in the United States (3), the United Kingdom (4), and France (5); encouragement from the Convention on Biological Diversitys (CBDs) scientific advice body (6); and the issue on the agenda for next months Conference of the Parties to the CBD, we see a chance for global-scale policy change. We extend beyond the IPBES report, which we helped to write, and suggest 10 policies that governments should seriously consider to protect pollinators and secure pollination services. Our suggestions are not the only available responses but are those we consider most likely to succeed, because of synergy with international policy objectives and strategies or formulation of international policy creating opportunities for change. We make these suggestions as independent scientists and not on behalf of IPBES.

Adaptive community-based biodiversity conservation in Australia's tropical rainforests

In the globally significant Australian tropical rainforests, poor performance of community-based natural resource management (CBNRM) approaches mandated by national policy highlights the importance of the global search for better models. This paper reports on co-research to develop, apply and test the transferability and effectiveness of a new model and tools for CBNRM in biodiversity conservation. Adaptive co-management, designed with specific communities and natural resources, recognized as linked multi-scalar phenomena, is the new face of CBNRM. New tools used to achieve adaptive co-management include a collaborative focal species approach focused on the iconic southern cassowary, scenario analysis, science brokering partnerships, a collaborative habitat investment atlas and institutional brokering. An intermediate-complexity analytical framework was used to test the robustness of these tools and therefore likely transferability. The tools meet multiple relevant standards across three dimensions, namely empowering institutions and individuals, ongoing systematic scientific assessment and securing effective on-ground action. Evaluation of effectiveness using a performance criteria framework identified achievement of many social and environmental outcomes. Effective CBNRM requires multi-scale multi-actor collaborative design, not simply devolution to local-scale governance. Bridging/boundary organizations are important to facilitate the process. Further research into collaborative design of CBNRM structures, functions, tools and processes for biodiversity conservation is recommended.

Empowering Indigenous peoples’ biocultural diversity through World Heritage cultural landscapes: a case study from the Australian humid tropical forests

Australian humid tropical forests have been recognised as globally significant natural landscapes through world heritage listing since 1988. Aboriginal people have occupied these forests and shaped the biodiversity for at least 8000 years. The Wet Tropics Regional Agreement in 2005 committed governments and the region’s Rainforest Aboriginal peoples to work together for recognition of the Aboriginal cultural heritage associated with these forests. The resultant heritage nomination process empowered community efforts to reverse the loss of biocultural diversity. The conditions that enabled this empowerment included: Rainforest Aboriginal peoples’ governance of the process; their shaping of the heritage discourse to incorporate biocultural diversity; and their control of interaction with their knowledge systems to identify the links that have created the region’s biocultural diversity. We recommend further investigation of theory and practice in Indigenous governance of international heritage designations as a means to empower community efforts to reverse global biocultural diversity loss.

Kuku-Yalanji rainforest aboriginal people and carbohydrate resource management in the wet tropics of Queensland, Australia

Carbohydrate food sources have emerged as a critical factor limiting occupation of rainforests by hunter—gatherer peoples globally. In the wet tropics bioregion of northeastern Australia, Kuku–Yalanji aboriginal people occupied the rainforests through a hunter–gatherer subsistence economy prior to European occupation. Collaborative environmental research between a researcher at the James Cook University and Kuku–Yalanji people has established that their fire management protected carbohydrate resources in the fire-sensitive rainforests and their margins, and ensured ongoing access to the critical dry season carbohydrate resource, Cycas media, growing in patches of fire-prone open forest on each clan estate. Carbohydrate resources in the wet season were obtained predominantly from seeds of rainforest tree nuts, a high proportion of which are wet tropics endemic species. Several of the genera utilized by aboriginal people in the wet tropics bioregion also occur in the rainforests of eastern Cape York Peninsula, where they were not utilized as foods. It is hypothesized that use of rainforest seeds for carbohydrate is a cultural adaptation that occurred in the wet tropics bioregion, stimulated by the unique availability of the substantial number of large-seeded rainforest trees that are wet tropics endemics. The implications of these data for concepts about the impact of aboriginal fires on Australian rainforests are considered. Aboriginal fires imposed a fine patterning on the vegetation at the local scale, with little effect on the vegetation at the regional scale, which is determined by environmental factors.

Why biodiversity declines as protected areas increase: the effect of the power of governance regimes on sustainable landscapes

Achieving sustainable landscapes that integrate food production with biodiversity conservation remains challenging, particularly in the tropics where most forest clearance results from conversion to industrial agriculture. Land-sparing (delineating protected areas and intensifying agricultural production from developed land) has often been identified as more effective than land-sharing (mixing protection and production in an agro-ecological matrix) for biodiversity in the tropics. Nevertheless, biodiversity decline continues despite protected area expansion meeting global targets under international conventions. We developed a low-order stock-and-flow model to consider this apparent paradox, and used it to structure deliberations on the impacts of the power of governance regimes. The model articulates our shared hypothesis about the basic dynamics of the social–ecological system. We present scenarios that depict plausible biodiversity change over time under three different governance regimes and land-use trajectories. The scenarios raise the possibility that, while land-sparing gives better short-term results for biodiversity, land-sharing may outperform it over time. Two key insights derive from our deliberations. First, the forces that drive forest clearance for development do not necessarily oppose those that drive forest protection; this decoupling helps explain why biodiversity loss continues as protected areas increase. Second, the power of the governance regimes that protect existing forest can be weakened by protected area expansion, through lowering public discourse about risks from biodiversity loss, while the power of governance regimes for development concurrently remain strong; this helps explains why some REDD+ schemes are associated with increasing deforestation. These insights suggest novel leverage points for sustainable tropical landscapes, such as prioritising protected area placement by proximity to active agricultural frontiers, rather than by representative biodiversity or cost-effectiveness; or using area-based conservation targets that include both the extent of protected areas and of other remaining forest habitat. We recommend further investigation of these ideas, and of collaborative conceptual modelling approaches, to explore solutions for sustainable tropical landscapes.
