What Makes Them Pay? Values of Volunteer Tourists Working for Sea Turtle Conservation

As charismatic mega-fauna, sea turtles attract many volunteers to conservation programs. This article examines the ways in which volunteers value sea turtles, in the specific context of volunteers working with the Caribbean Conservation Corporation, at Tortuguero, Costa Rica. The complexity of volunteer values is explored using a qualitative approach. In-depth interviews with 31 volunteers were conducted in July of 1999 and 2000. Interviews probed, among other things, interest in sea turtles and their conservation, motives for participating, and the most gratifying parts of their volunteer experience. Results show that volunteers hold multiple and complex values for sea turtles, but particular values dominate. Results have implications for understanding human–environment relations and the emerging study of volunteer tourism. There are also management implications for volunteer programs hoping to attract participants.     

What is a static head measurement? Evaluating structural error and implications for regional groundwater modeling

Most groundwater modelers avoid using static heads measured from active production wells because they can introduce a bias into model calibration. However, in the deep confined Cambrian-Ordovician Sandstone Aquifer System in the Central Midcontinent of North America, dedicated observation wells are sparse and remote from areas of most concentrated pumping. As a result, in areas where drawdown is the greatest and modeling is most needed, only static heads from production wells are available for calibration. This paper evaluates two leading sources of discrepancies in using production well data, spatial and temporal structural error (S.E.). A simple Theis solution is used to evaluate the potential magnitude of spatial S.E. when calibrating a regional MODFLOW model with coarse cell resolution. Despite theoretical analyses indicating that spatial S.E. could be significant, statistical analysis of the model results suggests that temporal S.E. is dominant. Long (ranging over decades) or frequent (monthly) head datasets are key in understanding temporal S.E., to better capture water-level variability. In this study, the range in static head observations impacted estimates of the remaining time a well could extract water from the aquifer by 0.1 to 16.0 years. This uncertainty in future water supply is highly relevant to stakeholders and must be assessed in hydrographs depicting risk.     

From “What is” to “What Should Become” Conservation Biology? Reflections on the Discipline’s Ethical Fundaments

In this essay, I build on the article by Soulé that established the foundation for the field of conservation biology. I analyze the presuppositions that have guided the discipline’s ethics in the 30 years since that article first appeared. I argue that conservation biology’s normative postulates introduced a paradigm shift that placed the diversity of the biota instead of the biota itself at the center of its ethics. I show that the ensuing priorities in the valuation of nature entail several contradictions at the ethical level and are justifiable only through scientific postulates. Identifying potential revisions and latent ideological issues in science, I defend the position that such scientific legitimization of conservation measures becomes disputable when this option undermines the ethical status of non-human life. Furthermore, I explain the absence of social feedback regarding conservation measures from the perspective of this shift. I conclude with an invitation to critically rethink the ethical basis of conservation sciences so that these fields may achieve their intention of playing a key role in halting the destruction of nature and in encouraging society’s support.     

Exploring the determinants for adopting water conservation measures. What is the tendency of landowners when the resource is already at risk?

In Finland, the current water conservation policy sets equal incentives for water conservation, regardless of the environmental condition. Before any policy reform, it is vital to investigate the tendency of landowners to adopt water conservation measures. In this study, we were interested in examining adoption if the soil quality implies a high leaching risk and if the water quality is already poor. By combining survey data with GIS data, we analysed the effect of farm and farmer characteristics and attitudes towards adoption. Our probit models indicated that financial variables were the key determinants of adoption for active farmers, whereas for passive owners, adoption was also explained by attitudes. In contrast to our expectations, adoption in areas under risk was weakly supported by our estimates. Environmental awareness, providing it increases with risk, is not strong enough to motivate adoption. Targeted agri-environmental measures, even though costly, cannot be avoided, and spatially tailored measures can attract adopters in hotspot areas.     

The Idea of “Ethical Accounting” for a Livestock Farm

This paper presents the idea of a decision-support system for a livestock farm, called “ethical accounting”, to be used as an extension of traditional cost accounting. “Ethical accounting” seeks to make available to the farmer information about how his decisions affect the interests of farm animals, consumers and future generations. Furthermore, “ethical accounting” involves value-based planning. Thus, the farmer should base his choice of production plan on reflections as to his fundamental objectives, and he should make his final decision only after having seriously considered the various consequences for the affected parties. This revised version was published online in August 2006 with corrections to the Cover Date.     

Are Farmers of the Middle Distinctively “Good Stewards”? Evidence from the Missouri Farm Poll, 2006

In this paper we consider the question of whether middle-scale farmers, which we define as producers generating between 100,000 and100,000 and 250,000 in sales annually, are better agricultural stewards than small and large-scale producers. Our study is motivated by the argument of some commentators that farmers of this class ought to be protected in part because of the unique attitudes and values they possess regarding what constitutes a “good farmer.” We present results of a survey of Missouri farmers designed to assess farmer attitudes and values regarding a variety of indicators of farmer stewardship, such as the most important issues in agriculture, environment, and treatment of farm animals, perspectives on the past and future of agriculture, and ethical behavior. We find little evidence that farmers-of-the-middle are particularly noteworthy in these regards. We do find evidence, however, that middle-scale farmers are more pessimistic and anxious about their role in the future of agriculture.     

Developing decision support systems for integrated coastal management in the tropics: is the ICM decision-making environment too complex for the development of a useable and useful DSS?

Integrated coastal management in the tropics requires the conservation of vulnerable and diverse ecosystems such as coral reefs and mangroves as well as the management of land and marine-based human activities. Decision-making for integrated coastal management involves multiple decision-makers and multiple stakeholders often with conflicting needs and interests. Decision support systems can be developed to improve our understanding of the inter-relationships between the natural and socio-economic variables and hence result in improved decision-making. The question is whether this decision making environment is actually too complex for the development of useful and useable decision support systems. This paper describes the components of the decision making environment and the components of a decision support system. It also explores the various techniques available to deal with different modelling needs, the constraints of inadequate data and the multi-objective decision making environment. In addition, different techniques of developing decision support systems can play important roles within integrated coastal management. Three coastal decision support systems are evaluated in terms of their design and role in integrated coastal management and are used to evaluate the potential to develop decision support systems for integrated coastal management.     

Social licences to operate: for better not for worse; for richer not for poorer? The impacts of unplanned mining closure for “fence line” residential communities

Establishing “social licences to operate” with communities has become a significant corporate social responsibility agenda. The complex dynamics of these relationships can compound the impacts for communities when these contracts are not upheld. This article documents reflections from a rapid rural appraisal conducted in the Shire of Ravensthorpe in remote Western Australia after the Ravensthorpe Nickel Operation was “mothballed” 9 months into a projected 25-year lifespan. It captures how communication about the project and its time frames created a sense of consistency, predictability, certainty and trust – enabling social licence. The raising of hope and the emergence of mistrust underpin social, environmental and financial impacts of this event for the local community. Embedded in the theoretical dimensions of social licences, this case study highlights the problematic of social licences that engage with non-contractual stakeholders as partners in “booms” but have no legal responsibility towards them in times of “bust”.     

Can you tell a green field from a cold steel rail? Examining the “green” of Green Infrastructure development

The rapid development of Green Infrastructure as an approach to planning has enabled landscape practitioners to implement a range of projects utilising its principles. Discussions though exist examining what Green Infrastructure is, how it should be planned, and whether it can be identified as only those elements of the landscape that are green. A further element of this argument examines the use of water within this process. Therefore, as planners, we can ask: can we tell a green field from a cold steel rail? Both may have a green or sustainable function with only the visual appearance differing. Debates, however, focus on practitioner selectivity of the interpretation of “green” infrastructure planning exploring whether physical landscape characteristics or the function of an investment is the main focus of discussion. Using the grey–green continuum developed by Davies et al. [2006. Green infrastructure planning guide project: Final report. Annfield Plain: NECF], this paper examines whether geographical differences exist in the application of the Green Infrastructure and examine how practitioners use the ambiguity of Green Infrastructure planning to guide investment. Drawing on academic and practitioner literature provides this paper with a balance of conceptual and process-based assessments evaluations of global Green Infrastructure focusing on the design and implementation of terrestrial and marine resources. This paper also examines whether the dominant landscape planning framework in each region could be considered contradictory to the wider application of Green Infrastructure principles.     

Who Visits a National Park and What do They Get Out of It?: A Joint Visitor Cluster Analysis and Travel Cost Model for Yellowstone National Park

Yellowstone National Park visitor data were obtained from a survey collected for the National Park Service by the Park Studies Unit at the University of Idaho. Travel cost models have been conducted for national parks in the United States; however, this study builds on these studies and investigates how benefits vary by types of visitors who participate in different activities while at the park. Visitor clusters were developed based on activities in which a visitor participated while at the park. The clusters were analyzed and then incorporated into a travel cost model to determine the economic value (consumer surplus) that the different visitor groups received from visiting the park. The model was estimated using a zero-truncated negative binomial regression corrected for endogenous stratification. The travel cost price variable was estimated using both 1/3 and 1/4 the wage rate to test for sensitivity to opportunity cost specification. The average benefit across all visitor cluster groups was estimated at between $235 and $276 per person per trip. However, per trip benefits varied substantially across clusters; from $90 to $103 for the “value picnickers,” to $185–$263 for the “backcountry enthusiasts,” $189–$278 for the “do it all adventurists,” $204–$303 for the “windshield tourists,” and $323–$714 for the “creature comfort” cluster group.     

“Alternative futures”: a methodology for integrated sustainability considerations,the case of Nuremberg West,Germany

In the context of the desire to steer urban transformation towards sustainability transition, the development of proposals for alternative futures assists policy-makers and practitioners in focusing on impact by organising the various drivers, particularly spatial ones that cause an interactive urban system to transit. This paper presents the methodology that has been developed by the Chair for Urban Development, Munich University of Technology (TUM) as it was working within an inter-disciplinary research team on a project commissioned by the municipality of Nuremberg. The objective of this project was to develop ideas for regenerating the formerly industrial area of Nuremberg West (NW) under the guiding theme of sustainable urban development. This methodology focuses on the development of proposals of positive and possible transformations of NW in the year 2050 based on the analysis of economy, housing and space at various scales and a systematic assessment of trends. These alternative futures became framing and guiding narratives to internalise and anchor the debate in-between the various disciplines involved in this project.     

The incidence of electromagnetic pollution on wild mammals: A new “poison” with a slow effect on nature?

A review on the effects of radiofrequency radiation from wireless telecommunications on living organisms and its possible impact on wild mammals are presented. Physical and technological characteristics of mobile telephone and phone masts, the scientific discoveries that are of interest in the study of their effects on the wildlife, action mechanisms on biological systems and experimental difficulties are described. Keeping in mind that electromagnetic pollution (in the microwave and radiofrequency range) is a possible source for decline of some mammal populations, it is of great importance to carry out studies on the effects of this new pollutant to wildlife. Some research types that could be useful to determine adverse health effects are proposed.     

“Housing for all” at the era of financialization; can (post-disaster) cities become truly socially resilient and egalitarian?

This paper examines the realism of the resilience ambition and process of the U.S. housing system, shedding light on its heterogeneity as well as the financialization currently acting as the driving force in real estate production. The resilience ambition leading to enhanced justice and egalitarianism is understood as the provision and maintenance of post-disaster housing for all within an institutionally diverse landscape of housing policy makers and implementers. Particular emphasis is given to the post-Katrina institutional transformations resulting from multifarious interactions between multilevel institutional structures and a diverse landscape of low-income housing policy implementers – referred as social resilience cells (SRCs) in this paper. The nature and level of these transformations determine the degree to which resilience in its heterogeneous form has been incubated in New Orleans. The paper concludes with a discussion on the macro conditions and bottom-linked governance structures under which all SRCs could be better bolstered in a post-financialization, radicalised neowelfare U.S., and which in turn create possibilities for materialising the resilience ambition.
