Drivers of landholder participation in tender programs for Australian biodiversity conservation

Conservation tender program have been widely applied to biodiversity conservation in Australia and internationally in recent decades. Increasing participation rates is critical to these schemes, as competition is required for the cost-effectiveness benefits of the tender system to be fully realized. However, knowledge relating to the drivers of landholder participation in tender programs is limited. This study aims to identify the relative importance of different drivers of participation in Victorian conservation tenders. The novel method of maximum entropy ordinal regression is used given the small sample size, and supplemented with qualitative data obtained through face-to-face interviews. The regression analysis reveals that strong relationships between agencies and landholders and a low administrative burden drive increased participation. The provision of education, support, and easily-integrated management practices, however, may drive lower participation, with landholders confident to undertake conservation activities independently of assistance. Some evidence emerges that ten-year contracts may be well-received. A key concern is low additionality in biodiversity benefits, with typical tender participants displaying a strong conservation ethic and high levels of management activity pre-participation. This work has shown that in conservation policies involving self-selection by participants, economic incentives for adoption may be less important than non-monetary drivers.     

Decline of ‘biodiversity’ in conservation policy discourse in Australia

Market-based instruments along with conceptualizing the environment as a collection of ‘ecosystem services’ has become increasingly common within environmental and conservation policy. This kind of thinking is also increasingly prominent in the public discourse surrounding environment and conservation policy, particularly in the context of communicating the importance of policy measures. Language used in public discourse can have a powerful influence on how people engage with policy issues, and changes within the biodiversity and conservation discourse may have consequences for public engagement in conservation. We explored how these factors are changing with time by documenting the use of the terms ‘bio’ and the prevalence of economic language in the text of 3553 media releases between 2003 and 2014 from the Australian Government environment portfolio, and 1064 media releases from the Australian Conservation Foundation (ACF). Results show that in the last decade, the term ‘biodiversity’ has become less prevalent whilst economic language has increased in both Australian Government and ACF communication. A further content analysis in a subsample of 745 media releases explored the prevalence of ecosystem services framing, results indicating that it has become a mainstream concept. While this may reflect a strategic response by these agencies to better engage with both the general public and decision makers within what is an increasingly dominant neoliberal paradigm, we argue it may also have unintended (possibly adverse) impacts on how people think about and engage with biodiversity conservation.     

Indigenous benefits and carbon offset schemes: An Australian case study

The nexus between human rights and the environment is a key issue for climate policymakers and Indigenous peoples around the world. We combine national spatial, social and biological datasets from Australia to describe where Indigenous carbon projects are happening, why Indigenous people are participating, and how effective these schemes might be at marrying Indigenous co-benefit, biodiversity and carbon emission mitigation goals. Our study shows that many Indigenous people engage in carbon offset schemes as part of their broader cultural responsibility for landscapes, and that they seek to grow the relationship between social and ecological benefits. It also highlights the challenges associated with designing carbon offset schemes that address the impacts of climate change and respond to Indigenous peoples’ world views about what is required to sustain cultural-social-ecological systems.     

Threatened species listing as a trigger for conservation action

Legislative listing schemes, under which the listing of a species as threatened automatically triggers command regulation and/or recovery planning, raise significant issues for policy makers. In this paper, we explore strategies for factoring considerations beyond the empirical assessment of a species’ conservation status into the resource allocation decisions that flow from listing. Even in threatened species legislation that appears to prioritise species conservation over socio-economic considerations by creating an automatic nexus between listing and conservation response, there are significant pressure valves that allow the latter to exercise a significant influence on decisions in practice. We critically examine two other techniques currently used in legislation that allow a broader range of considerations to be factored into resource allocation decisions: abandoning the automatic triggering of resource allocation by listing; and taking into account a broader range of considerations in the listing decision itself. We conclude by outlining the framework for a strategic approach to the allocation of conservation resources. This has three limbs to it: recovery plans that identify what needs to be done to bring about recovery, in addition to what available resources will allow us to do; a system for prioritising between the implementation of recovery plans; and the integration of threatened species conservation into strategic land use planning processes.     

Game theory approach to the analysis of inter-plant water integration in an eco-industrial park

Industrial water conservation is an important adaptation to the effects of climate change. In addition to water conservation within individual plants, wastewater can be reused/recycled among different companies through inter-plant water integration (IPWI) schemes. Such schemes are based on the concept of industrial ecology and industrial symbiosis, and can be used to achieve greater water savings than when water conservation is implemented in individual companies separately. However, in IPWI, each participating company seeks to maximise its own benefits. In the absence of centralised authority dictating the terms of water integration schemes, conventional modelling techniques are not appropriate. This paper shows how a game theory-based approach can be used to analyse the interaction of participating companies in an eco-industrial park seeking to develop an IPWI scheme.     

The threat of abandonment in socio-ecological landscapes: Farmers’ motivations and perspectives on high nature value grassland conservation

Future sustainability of the conservation management of socio-ecological landscapes is typically reliant on on-going agricultural management. Such management may be threatened by changes in the drivers of management and the fragility of the stakeholder networks that deliver management. This study examined evidence for the risk of abandonment in a series of case study high nature value (HNV) grassland sites. The work found that the motivation of farmers to participate in the conservation management was typically limited and often marginal. Landowners and conservation stakeholders who relied on partner farmers to manage such sites often struggled to recruit and retain their participation, leading to increased turnover among managing farmers and to some sites being under-managed. Primary reasons for difficulty of recruitment and farmer turnover included a lack of candidate farmers in the local landscape, and the marginal and fluctuating economics of grassland management. A trend towards greater financial incentivisation of farmers was evident, which policy-makers responsible for agri-environment schemes should note, and elsewhere some conservation organisations were seen to be bringing grassland management in-house. Farmers’ motivations to participate in conservation management of such systems may continue to weaken and abandonment may therefore become a significant risk to the successful conservation of such systems. Conservation stakeholders need to foster good relations with their farmer-manager partners and not further depress their limited motivations to participate, as well as consider carefully whether farmer stakeholders are being adequately compensated for their efforts.     

House sparrows benefit from the conservation of white storks

As with many farmland bird species, the house sparrow Passer domesticus is declining in Europe, mainly due to intensification of agriculture reducing nest sites and food supplies. During 2002–2005, we studied the population size and nest site characteristics of house sparrows breeding within white stork Ciconia ciconia nests in a large area of agricultural landscape within western Poland. To explain sparrow density within stork nests, we examined characteristics of white stork nests (position, age, productivity) and the farm type around the nest. House sparrow density was greatest in the longest established (and hence larger) white stork nests located on traditionally managed farms. Two recent changes appear to have adverse effects on house sparrows. The first is the intensification of farming and the second is active management of white stork nests on electric poles to reduce nest size and thus avoid both disruption to the electrical supply and electrocution of white storks. Because the white stork has such a high profile in Poland, there are numerous schemes to conserve and enhance this species. In conclusion, we clearly show that protecting one species can have valuable, although unplanned, benefits to another species of conservation interest, the house sparrow.     

A methodology for the design of efficient resource conservation networks using adaptive swarm intelligence

The implementation of resource conservation schemes in industry can be enhanced through the application of systematic design methodologies. In particular, process integration methods allow resource consumption and waste generation in industrial plants to be reduced through the identification of efficient material reuse/recycle schemes. Various approaches, ranging from graphical pinch analysis to mathematical programming, have been developed by different researchers. Mathematical programming techniques provide considerable flexibility in the representation of network design problems, although in many cases, these approaches result in mixed integer non-linear programming (MINLP) models which are difficult to solve. This paper presents a simplified approach using a zero–one programming or “knapsack” formulation for the design of industrial material reuse/recycle networks. It is possible to solve the resulting model using an efficient heuristic algorithm based on adaptive particle swarm optimization. Two sample applications are provided to illustrate the methodology. The first case shows the application of the methodology to the implementation of industrial water conservation and the second case demonstrates its use in the design of a hydrogen gas reuse/recycle scheme in a refinery.     

Croppers to livestock keepers: livelihood transitions to 2050 in Africa due to climate change

The impacts of climate change are expected to be generally detrimental for agriculture in many parts of Africa. Overall, warming and drying may reduce crop yields by 10–20% to 2050, but there are places where losses are likely to be much more severe. Increasing frequencies of heat stress, drought and flooding events will result in yet further deleterious effects on crop and livestock productivity. There will be places in the coming decades where the livelihood strategies of rural people may need to change, to preserve food security and provide income-generating options. These are likely to include areas of Africa that are already marginal for crop production; as these become increasingly marginal, then livestock may provide an alternative to cropping. We carried out some analysis to identify areas in sub-Saharan Africa where such transitions might occur. For the currently cropped areas (which already include the highland areas where cropping intensity may increase in the future), we estimated probabilities of failed seasons for current climate conditions, and compared these with estimates obtained for future climate conditions in 2050, using downscaled climate model output for a higher and a lower greenhouse-gas emission scenario. Transition zones can be identified where the increased probabilities of failed seasons may induce shifts from cropping to increased dependence on livestock. These zones are characterised in terms of existing agricultural system, current livestock densities, and levels of poverty. The analysis provides further evidence that climate change impacts in the marginal cropping lands may be severe, where poverty rates are already high. Results also suggest that those likely to be more affected are already more poor, on average. We discuss the implications of these results in a research-for-development targeting context that is likely to see the poor disproportionately and negatively affected by climate change.     

Ecological and social aspects of biodiversity conservation on private lands

In recent decades, the growing need for biodiversity conservation and the different means of achieving it have been defined in international and national procedures regulated by governments and parliaments on the one hand, and in governance processes run by different stakeholders on the other. In local contexts, however, people perceive the abstract phenomenon of biodiversity conservation through the environment in which they live and through their social and cultural positions. We examine Finnish forest owners’ experiences and perceptions of biodiversity conservation, and consider the compatibility of these perceptions with national conservation policy. Our work is based on a survey of forest owners and the content analysis of national policy documents. We found that the perceptions of forest owners and the documents of nature conservation policy had elements that both overlapped and contradicted each other, thus reflecting different interpretations of forest ownership and biodiversity conservation. Moreover, the national Forest Biodiversity Program – an outcome of a multilateral governance process – was more successful in combining conservation policy with various perspectives of forest owners than was the authoritatively formulated Nature Conservation Act and Decree. This result indicates that governance processes can address conflicts of interest in the use of natural resources.     

Citizen science for policy development: The case of koala management in South Australia

Citizen science involves the engagement of non-scientists in scientific research. Citizen science projects have been reported to be useful in policy development but there is little detail of how projects have contributed. The citizen science project, the Great Koala Count (GKC) collected ecological data about koalas and social data that have been used in the initial stages of the development of a South Australian Government koala management and conservation policy. After the GKC, we conducted an online survey of people who participated in the project and a control group. The survey focussed on opinions towards possible management options for koalas in South Australia. GKC participants were also asked about project-related changes in knowledge and opinions. We received 970 valid surveys and found some differences in opinions between GKC participants and the control group. Therefore, the GKC did not provide a representative sample of the entire South Australian population. However, we contend that the data from the citizen scientists are still valuable for policy development as it has been provided by people who are highly engaged in the topic (koala management in this case). It can be difficult to engage the public in the policy development process, and the citizen science project enabled the collection of a wide range of opinions, helping to discover and define relevant issues. Additionally, many people learnt about koalas and koala-related management issues, and some changed their opinions regarding koala management, also useful outcomes from the project in the policy development context. Our findings suggest that citizen science is useful for policy makers because projects provide the opportunity for dialogue with the people most interested in the topic of the project.

Bottom-up perspectives on nature conservation systems: The differences between regional and local administrations

Many proposals to improve biodiversity governance target the stage of policy formulation. In this paper we highlight the importance of the subsequent policy realization stage, which is mostly carried out by sub-national administrative levels. We explore the differences in the opinions of practitioners representing regional and local public institutions in conservation policy design and implementation. The research was conducted through surveying a representative sample of local and regional practitioners within Małopolska, Poland. The results illustrate a cross-level mismatch between the regional and local practitioners. That is, practitioners operating at different administrative levels have significantly different opinions on nature conservation system performance, system effectiveness, the distribution of power among actors, and on the allocation of costs and benefits stemming from nature conservation. Local level representatives are generally more pleased with overall nature conservation performance and its outcomes, while regional level representatives are more skeptical, especially toward local level performance and the overall effectiveness of nature conservation. Also, local level respondents are more critical, while regional practitioners hold more positive images of the procedures involved during policy implementation. We highlight the practical implications of this kind of research, and the importance of quantitative data in evaluating the overall performance of conservation policy.     

采用保护性耕作对减少水稻产量损失的实证分析——基于4省1080个稻农的调研数据

干旱和洪涝是造成水稻减产最主要的自然灾害,稻农通过采用保护性耕作可以减少其对水稻的产量损失。基于2013—2015年中国水稻主产区1 080个水稻农户的调研面板数据,论文采用内生转换模型,实证分析了稻农通过采用保护性耕作应对干旱或洪涝的效果,并分别估计了采用者和未采用者的水稻单产情况。实证结果表明:1)采用者的水稻单产远远高于未采用者的水稻单产;2)在反事实假设情况下,如果采用者未采用保护性耕作,其水稻产量将相应减产457.95 kg/hm~2(约7%);如果未采用者采用保护性耕作,其水稻产量将相应增产225 kg/hm~2(约4%);3)户主种植经验、受教育年限和公共服务可得性正向影响稻农的采用行为。最后,论文建议政府应大力推广保护性耕作技术,加大对抗逆水稻品种的培育,加强对农业生产资料的投入和管理,扩大公共服务的覆盖范围。     

The reproductive choices of eavesdropping female black-capped chickadees,<Emphasis Type="Italic"> Poecile atricapillus</Emphasis>

In animals where males engage in signalling interactions, females might evaluate male–male contests to inform their reproductive choices. We used interactive playback to engage territorial male black-capped chickadees (Poecile atricapillus) of known dominance status in countersinging contests with an aggressive or submissive opponent. Previous analysis of these data showed that high-ranking males who received aggressive playback were more likely to be cuckolded. Here we describe the particular reproductive decisions of females whose partners received aggressive versus submissive playback. The proportion of extra-pair young per brood was higher for females paired to high-ranking males that received aggressive playback compared to submissive playback, and similar to levels in broods of females paired to low-ranking males. We found no strong predictors of whether high-ranking subjects lost paternity following aggressive playback. Females usually preferred extra-pair sires with high dominance status. When females had extra-pair fertilizations with low-ranking males, females chose males who had received submissive playback. We conclude that females mated to aggressive-playback, high-ranking males pursued mixed mating strategies similar to those of females mated to low-ranking males. Our results support the idea that male performance in song contests may influence multiple aspects of female reproductive choices.     

Getting REDD to work locally: lessons learned from integrated conservation and development projects

Integrated conservation and development projects (ICDPs) have been a pervasive, although widely criticized, approach to tropical conservation for more than 20 years. More recently, international conservation discourse has shifted away from project-based approaches and towards reducing emissions from deforestation and forest degradation (REDD). While REDD is based upon experience with payment for environmental services (PES) initiatives and forest-related discussions in the United Nations (UN), REDD implementation will still require sub-national projects. Issues of equity will likely pit these sub-national projects against some of the same challenges that have dogged ICDPs. This suggests that REDD project developers stand to learn a great deal from the lessons generated by experience with ICDPs. This paper provides a list of best practices for ICDPs and applies their lessons as principles to guide the development and implementation of sub-national REDD projects. The intent of this approach is to encourage the design and implementation of sub-national REDD projects in a way that avoids the past pitfalls and mistakes, while building upon some successes, of the ICDP conservation approach. By doing so, REDD will be more likely to be implemented in a way that is effective, efficient and equitable.     

Product development and responsible consumption: designing alternatives for sustainable lifestyles

This paper presents insights from a research project that examines the notion of ‘responsible consumption’, its relationship to consumer preferences and expectations, and its implications for product design and development. The paper discusses the issue of sustainable consumption in relation to product development and summarizes initial findings from a study conducted among people who consider themselves responsible consumers. Notably, four different profiles of ‘simplifiers’ are described. The study shows that people who took part in the research adopt more sustainable lifestyles not only because of an ecological consciousness, but also because of perceived personal factors or benefits. The study also reveals that participants have both a close and distant relationship to objects and that they prefer products that allow them to be engaged in the activity of “doing”. Product development strategies informed by these insights are explored. The paper suggests that product designers can support and encourage those already active or interested in orienting their consumption habits towards more sustainable solutions by envisioning appropriate ecologically and socially responsible product alternatives.     

The Nature Conservancy's approach to prioritizing conservation action

Like many conservation organizations and federal and state agencies, The Nature Conservancy is in the process of large-scale planning and prioritization efforts. To improve the efficiency of these planning efforts, the Conservancy has developed a methodology for these efforts. The results of these planning efforts will be a conservation blueprint which identifies the conservation areas necessary for conserving biodiversity and a subset of those areas where the Conservancy will focus its immediate efforts over the next 10 years. The subset of all the conservation areas identified in the planning process help The Nature Conservancy determine where it will work. This subset of areas (referred to as action sites) is selected using a tool which ranks key criteria for each conservation area. These criteria include the current conservation status of each area, complementarity to other areas selected, the diversity and viability of targets at the area, the urgency and degree of threats to the targets, the feasibility or opportunity to abate the threats at the area and the leverage potential of working at a conservation area. Taken together, these criteria help planners to select the areas where they will focus their conservation efforts.     

Optimal retrofit of water conservation networks

This paper presents a new general mathematical programming model for the optimal retrofit of material conservation networks considering recycle, reuse and regeneration schemes (notice that most of the previously reported methods only have considered the synthesis case, and nowadays it is very important to have strategies for the retrofit of water networks because several existing water network are functioned under suboptimal conditions because these were synthesized using inefficient approaches or because the process and environmental constraints have changed). The model considers the reconfiguration of existing networks to satisfy stricter process and environmental constraints considering the repiping for the network, the reuse of the existing treatment units, the modification for the capacity and performance of the existing units and the installation of new treatment units to reduce the overall operating cost through the reduction of the use of fresh sources. The objective function accounts for the minimization of the total annual cost associated to the retrofit process. This retrofit process involves simultaneously economic (because the reduction of the fresh sources costs) and environmental (because the reduction of the waste streams discharged to the environment and with a better quality) improvements. The applicability of the proposed model is proved through a set of example problems addressed, where no numerical complications were observed. In addition, the proposed approach is general and it can be applied to any specific case with the information required.     

Cost-effective forest conservation and criteria for potential conservation targets: a Finnish case study

Selecting reserves for forest biodiversity maintenance is often done by setting criteria for components of structural elements of biodiversity, such as a volume of decaying wood. We tested how the different threshold values for the components of structural elements affect the cost-effective site selection. Using Finnish National Forest Inventory information and remote sensing data, we determined a habitat quality index and economic value for each site in Satakunta region in Finland. Moreover, we defined several sets of potential conservation targets using alternative criteria for the habitat quality index developed for the Finnish case study. These figures were used in the site selection model in order to maximize the sum of habitat index of selected areas under a given budget constraint. We found that the production possibility frontier for the outputs of timber and biodiversity is only slightly concave when using the given threshold values. Thus, the optimal combination of the outputs is sensitive to the relative values of these goods. Our results suggest that an integrated approach in forest conservation could provide to environmental managers considerable cost savings compared with current management practices. Environmental managers could also reduce conservation costs by loosening the criteria for potential conservation targets. This would not lower considerably the quality of conserved forests.
