Challenges in assessing the vulnerability of species to climate change to inform conservation action
Butt, N. H.P. Possingham, C. De Los Rios, R. Maggini, R.A. Fuller, S.L. Maxwell, J.E.M. Watson (in press) Challenges in assessing the vulnerability of species to climate change to inform conservation actions. Biological Conservation. Accepted April 15th. 2016 Understanding climate change impacts on species is vital for correctly estimating their extinction risk and choosing appropriate conservation actions. We perceive four common challenges that hamper conservation planning
The inequity in climate change
The countries responsible for most greenhouse emissions incur the least impacts whereas those least responsible bear the greatest cost. How unfair is that? Read full story here.
Does the social equitability of community and incentive based conservation interventions in non-OECD
An increasing number of conservation interventions aim to reduce their negative impacts on vulnerable people and to provide incentives aimed at improving overall human well-being. Community and incentive based conservation interventions have had variable rates of success in producing well-being outcomes, yet it is unclear why. Researchers have hypothesised that socially equitable conservation interventions will improve their likelihood of success. However, for community and i
Seeking convergence on the key concepts in ‘no net loss’ policy
Summary Biodiversity conservation policies incorporating a no net loss (NNL) principle are being implemented in many countries. However, there are linguistic and conceptual inconsistencies in the use of terms underlying these NNL policies. We identify inconsistencies that emerge in the usage of eight key terms and phrases associated with NNL policies: biodiversity, frames of reference (i.e. baselines, counterfactuals), no net loss, mitigation hierarchy, biodiversity offset, i
The broad footprint of climate change from genes to biomes to people
Climate change impacts have now been documented across every ecosystem on Earth, despite an average warming of only ~1°C so far. Here, we describe the full range and scale of climate change effects on global biodiversity that have been observed in natural systems. To do this, we identify a set of core ecological processes (32 in terrestrial and 31 each in marine and freshwater ecosystems) that underpin ecosystem functioning and support services to people. Of the 94 processes
Large seasonal and diurnal anthropogenic heat flux across four Australian cities
Anthropogenic heat release is a key component of the urban heat island. However, it is often excluded from studies of the urban heat island because reliable estimates are not available. This omission is important because anthropogenic heat can contribute up to 4ºC to the urban heat island, and increases heat stress to urban residents. The exclusion of anthropogenic heat means the urban heat island effect on temperatures may be under-estimated. Here we estimate anthropogenic h
Catastrophic declines in wilderness areas undermine global environment targets
Humans have altered terrestrial ecosystems for millennia [1], yet wilderness areas still remain as vital refugia where natural ecological and evolutionary processes operate with minimal human disturbance [2, 3, 4], underpinning key regional- and planetary-scale functions [5, 6]. Despite the myriad values of wilderness areas—as critical strongholds for endangered biodiversity [7], for carbon storage and sequestration [8], for buffering and regulating local climates [9], and fo
Persistent disparities between recent rates of habitat conversion and protection and implications fo
Anthropogenic conversion of natural habitats is the greatest threat to biodiversity and one of the primary reasons for establishing protected areas (PAs). Here, we show that PA establishment outpaced habitat conversion between 1993 and 2009 across all biomes and the majority (n = 567, 71.4%) of ecoregions globally. However, high historic rates of conversion meant that 447 (56.2%) ecoregions still exhibit a high ratio of conversion to protection, and of these, 127 (15.9%) expe
Formulating smart commitments on biodiversity: lessons from the Aichi Targets
The world is currently not on course to achieve most of the Convention on Biological Diversity's Aichi Targets to address biodiversity loss. One challenge for those implementing actions to achieve them may be the complexity and lack of clarity in the wording of the targets, which also make it difficult to stimulate and quantify progress. Drawing on experience in developing and measuring indicators to assess progress toward targets, we identify four key issues: ambiguity, quan
Balancing ecosystem and threatened species representation in protected areas and implications for na
Balancing the representation of ecosystems and threatened species habitats is critical for optimizing protected area (PA) networks and achieving the Convention on Biological Diversity strategic goals. Here we provide a systematic approach for maximizing representativeness of ecosystems and threatened species within a constrained total PA network size, using Australia as a case study. We show that protection of 24.4% of Australia is needed to achieve 17% representation for eac
