Papua New Guinea (PNG) has an incredible variety of land and marine ecosystems, including many components of biodiversity that are unique in the world. PNG's land mass constitutes less than one percent of the world's land area, yet estimates suggest that the country has more than 5% of the world's biodiversity. PNG has been recognized therefore as an important region for biodiversity conservation (see Alcorn 1993; Beehler 1993 and references within). Recently, Conservation International (CI) has recognized PNG as one of the small number of critical tropical forest areas for conservation efforts. That priority reflects not just PNG's unique biodiversity but also the fact that sustainable use of PNG's natural resources has become an important issue, particularly relating to its large mineral deposits, oil and natural gas reserves, agricultural potential, and forestry production potential. CI's perspective highlights important principles of conservation priority. PNG, like the other tropical wilderness areas on its priority list, is regarded as an opportunity for effective conservation at relatively low cost, given that these wilderness regions are still largely intact and have low human population density. In our view, realizing such opportunities requires good planning. Biodiversity conservation in PNG can imply low realized opportunity costs or quite high realized opportunity costs, depending on whether biodiversity planning is used to find a balance among society's competing needs through tradeoffs. PNG is a region worthy of urgent conservation planning attention because potential high net benefits for society may be needlessly foreclosed through inefficient planning that does not address conflicts among various needs of society. The risk of losing those potential net benefits is a strong argument for conservation investment in PNG.
Managing the cumulative effects (CE) that arise from human and natural stressors is one of the most urgent and complex problems facing coastal and marine decision makers today. In the absence of effective processes, models, and political will, decisionmakers struggle to implement management strategies that effectively tackle cumulative effects. Emerging efforts to address cumulative effects provide a timely opportunity to assess the efficacy of a range of management strategies operating at different scales and in different legislative and cultural contexts. Using primarily qualitative methodologies including literature reviews, focus groups, and workshops, this paper compares cumulative effects approaches within the Reef 2050 Plan for the Great Barrier Reef Marine Park (GBRMP), Australia, with those in Aotearoa New Zealand (Aotearoa NZ). Both case studies illustrate that cumulative effects management is especially complicated by: fragmented legislative regimes and institutions that cannot account for cross-scale or cross-sector interactions; chronic data scarcity and high levels of uncertainty that make system-based assessments and predictions challenging; and often conflicting societal and economic expectations, values, and rights that are poorly integrated into management decision-making. By considering how these two cases align with transformational change characteristics, we draw several conclusions and establish priority actions regarding (1) how to mobilise resources and political will to address CE, (2) how to deal with data scarcity and uncertainty, and (3) how to promote comprehensive and inclusive CE management of coastal and marine areas.
HIGHLIGHTS:o Five public environmental interests are identified using questionnaires and a media analysis o The five public interests are presented using scientific storytelling and flow diagrams o The scientific storytelling approach proves to be useful at succinctly conveying complex interactions in human-environment systems
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
