Understanding the role and influence of social norms: lessons for NRM

Much has been written about social norms in disciplines such as law and economics but they are less studied in the field of Natural Resource Management (NRM). Although norms are acknowledged to be an influence on decision–making, they are difficult to identify and measure in the field and their role is often implicit or not well understood or articulated. This paper addresses an important knowledge gap by combining social norms theory with the specifics of a particular case study. We examined the influence of social norms on landholder behaviour in a small rural community undergoing demographic change in Australia. Findings from interviews with landholders and government agency personnel indicate that established norms within the farming community are influencing incoming landholders; and that new norms and practices have also emerged as a result of government investment through the local Landcare group. We suggest that a better understanding of social norms in different contexts will give rise to strategies that make NRM interventions more effective.     

Potential Applicability of Persuasive Communication to Light-Glow Reduction Efforts: A Case Study of Marine Turtle Conservation

Artificial lighting along coastlines poses a significant threat to marine turtles due to the importance of light for their natural orientation at the nesting beach. Effective lighting management requires widespread support and participation, yet engaging the public with light reduction initiatives is difficult because benefits associated with artificial lighting are deeply entrenched within modern society. We present a case study from Queensland, Australia, where an active light-glow reduction campaign has been in place since 2008 to protect nesting turtles. Semi-structured questionnaires explored community beliefs about reducing light and evaluated the potential for using persuasive communication techniques based on the theory of planned behavior (TPB) to increase engagement with light reduction. Respondents (n = 352) had moderate to strong intentions to reduce light. TPB variables explained a significant proportion of variance in intention (multiple regression: R ² = 0.54–0.69, P < 0.001), but adding a personal norm variable improved the model (R ² = 0.73–0.79, P < 0.001). Significant differences in belief strength between campaign compliers and non-compliers suggest that targeting the beliefs reducing light leads to “increased protection of local turtles” (P < 0.01) and/or “benefits to the local economy” (P < 0.05), in combination with an appeal to personal norms, would produce the strongest persuasion potential for future communications. Selective legislation and commitment strategies may be further useful strategies to increase community light reduction. As artificial light continues to gain attention as a pollutant, our methods and findings will be of interest to anyone needing to manage public artificial lighting.     

Establishing management standards: Selected examples of the normative approach

The importance of developing evaluative standards for judging the acceptability of impacts caused by recreation is common to all recent natural resource management frameworks. A normative model has been advanced as a useful way to conceptualize, collect, and organize empirical data representing standards for resource management issues. This article summarizes the findings from social and ecological research to illustrate the utility of the normative approach from a manager's perspective. The social data (e.g., encounter norms, proximity norms, and tolerances for launch wait times) were obtained from 13 different study sites, while the ecological data (e.g., tolerances for the amount of bare ground, size of fire rings, instream flows, and wildlife management practices) were collected at three specific sites and from one statewide survey, Findings from the social research indicated that encounter norms exist for particular types of contacts with certain types of visitors at particular places and for certain types of experiences. The recreationists reported norms for acceptable distances between individuals, encounters with others at campsites or attractions, and waiting times to run rapids. These social norm evaluation techniques were also shown to be transferable to normative evaluations of ecological impacts. The users had opinions about ecological impacts and were willing to express them. In addition, the ecological norms were of moderate to high intensity. It is argued that the usefulness of normative approaches lies in their ability to characterize group agreement about appropriate use conditions or impact levels for a particular recreation experience, thus providing the evaluative information needed to establish management standards.     

Formulating and implementing climate change laws and policies in the Philippines,Mexico (Chiapas), and South Africa: a local government perspective

Faced with the prospects of a changing climate, a small but increasing number of countries are developing legal and regulatory frameworks that explicitly address climate change. Moreover at least some of these laws and policies carve out substantial roles for local governments. The present paper surveys three countries from different regions in the Global South that have developed or are developing such laws and policies: the Philippines (Asia-Pacific), Mexico and more specifically its State of Chiapas (Latin America), and South Africa (Africa). It examines those experiences through two different lenses. The paper first reviews the steps by which those laws or policies were developed. For this review, criteria for effective consultative processes are proposed. The study then examines the three climate change laws or policies per se. To this end, a framework including four modes of multi-level urban climate governance (governing by regulation, governing through enabling, governing by provision, governing with representation and consultation) is utilised. The paper ends with synthetic conclusions as to which experiences represent promising practices, and what other lessons are relevant for countries embarking on such processes.     

Changing governance structures and the environment: economy–environment relations at the local and regional scales

Two substantive bodies of research have developed in recent years, both of which have a focus upon local and regional scales. First, there has been the development of work on changing forms of local and regional governance. This has drawn on a range of theoretical perspectives, including notions of institutional capacity, urban regime theory and neo-regulationalist accounts. Second, a body of research has developed into environmental policy and sustainable development, but this has largely been normative and undertheorized. While these two bodies of literature have developed separately, we believe there is merit in bringing the insights from each together. A focus on local environmental policy helps to broaden our understanding of local governance and problems of after-Fordist regulation. Such a project also helps to illuminate problems in implementing policy on the environment and sustainability. The examination of changing local and regional forms of governance allows us to identify new state spaces, which may provide opportunities for the strategic insertion of environmental objectives into economic development policies. This paper seeks to theorize such environment–economy relations and emerging multi-scalar forms of environmental governance, drawing upon case study research work in six UK local authority areas.

Comparative Assessment of Public Opinion on the Landscape Quality of Two Biosphere Reserves in Europe

The European Landscape Convention (2000) obligates European Union countries to identify and implement landscape quality objectives (LQOs) understood as the specification of public expectations and preferences concerning the landscape of a given area, expressed by competent public authorities. The convention emphasizes the important role of local community representatives in this field. In Poland, the implementation of the LQO concept was first undertaken in two regions with radically different landscape characteristics: (1) the West Polesie Biosphere Reserve and (2) the selected protected areas of the Roztocze–Solska Forest, nominated to the rank of a biosphere reserve. The first stage of the presented study was the recognition of public opinion on the quality of key features of landscape, based on a questionnaire (n = 470). The primary objective of the study was to provide an answer to the following questions: (1) Whether similar social expectations regarding landscape quality exist in spite of radically different landscape characteristics of the regions investigated (landscape quality is understood as spatial arrangement, scenic beauty, and lack of environmental pollution); (2) which landscape features are considered to be most preservation worthy by the representatives of both local communities; and (3) What processes or development impacts pose the greatest threat to the landscape quality of both regions according to the public opinion? The conducted comparative assessment revealed that it is possible to define a set of features fundamental to the quality of both areas and that representatives of local communities pointed out the same threats to the natural and cultural values of both regions investigated.     

Contextualisation of Local and Global Environmental Issues in North-east England: Implications for debates on globalisation and the 'risk society'

In this paper the authors explore data on environmental meanings, and the contextualisation of environmental concerns, that were obtained from a qualitative study of risks to health from air pollution. In-depth interviews were undertaken with 49 people living in two conurbations in north-east England. The findings highlight the importance of the local context (local history, experience, local knowledges and everyday existence) as an arena in which environmental meanings and concerns are constructed and negotiated, and how global environmental issues are also contextualised, and made sense of, within an explicitly local framework. These findings are used as a basis upon which to critically reflect upon the emphasis on globalisation within theoretical debates on 'risk society'.

Application of a Three-Dimensional Water Quality Model as a Decision Support Tool for the Management of Land-Use Changes in the Catchment of an Oligotrophic Lake

While expansion of agricultural land area and intensification of agricultural practices through irrigation and fertilizer use can bring many benefits to communities, intensifying land use also causes more contaminants, such as nutrients and pesticides, to enter rivers, lakes, and groundwater. For lakes such as Benmore in the Waitaki catchment, South Island, New Zealand, an area which is currently undergoing agricultural intensification, this could potentially lead to marked degradation of water clarity as well as effects on ecological, recreational, commercial, and tourism values. We undertook a modeling study to demonstrate science-based options for consideration of agricultural intensification in the catchment of Lake Benmore. Based on model simulations of a range of potential future nutrient loadings, it is clear that different areas within Lake Benmore may respond differently to increased nutrient loadings. A western arm (Ahuriri) could be most severely affected by land-use changes and associated increases in nutrient loadings. Lake-wide annual averages of an eutrophication indicator, the trophic level index (TLI) were derived from simulated chlorophyll a, total nitrogen, and total phosphorus concentrations. Results suggest that the lake will shift from oligotrophic (TLI = 2–3) to eutrophic (TLI = 4–5) as external loadings are increased eightfold over current baseline loads, corresponding to the potential land-use intensification in the catchment. This study provides a basis for use of model results in a decision-making process by outlining the environmental consequences of a series of land-use management options, and quantifying nutrient load limits needed to achieve defined trophic state objectives.     

Use of Aquaculture Ponds and Other Habitats by Autumn Migrating Shorebirds Along the Lower Mississippi River

Populations of many shorebird species are declining; habitat loss and degradation are among the leading causes for these declines. Shorebirds use a variety of habitats along interior migratory routes including managed moist soil units, natural wetlands, sandbars, and agricultural lands such as harvested rice fields. Less well known is shorebird use of freshwater aquaculture facilities, such as commercial cat- and crayfish ponds. We compared shorebird habitat use at drained aquaculture ponds, moist soil units, agricultural areas, sandbars and other natural habitat, and a sewage treatment facility in the in the lower Mississippi River Alluvial Valley (LMAV) during autumn 2009. Six species: Least Sandpiper (Calidris minutilla), Killdeer (Charadrius vociferous), Semipalmated Sandpiper (Calidris pusilla), Pectoral Sandpiper (C. melanotos), Black-necked Stilt (Himantopus himantopus), and Lesser Yellowlegs (Tringa flavipes), accounted for 92 % of the 31,165 individuals observed. Sewage settling lagoons (83.4, 95 % confidence interval [CI] 25.3–141.5 birds/ha), drained aquaculture ponds (33.5, 95 % CI 22.4–44.6 birds/ha), and managed moist soil units on public lands (15.7, CI 11.2–20.3 birds/ha) had the highest estimated densities of shorebirds. The estimated 1,100 ha of drained aquaculture ponds available during autumn 2009 provided over half of the estimated requirement of 2,000 ha by the LMAV Joint Venture working group. However, because of the decline in the aquaculture industry, autumn shorebird habitats in the LMAV may be limited in the near future. Recognition of the current aquaculture habitat trends will be important to the future management activities of federal and state agencies. Should these aquaculture habitat trends continue, there may be a need for wildlife biologists to investigate other habitats that can be managed to offset the current and expected loss of aquaculture acreages. This study illustrates the potential for freshwater aquaculture to provide habitat for a taxa at risk. With the rapid growth of aquaculture worldwide, the practices of this industry deserve attention to identify benefits as well as risks to wildlife.     

Norms for Behavior and Conditions in Two National Park Campgrounds in Korea

/ This study was conducted to examine norm prevalence, norm agreement, and norm stability in an international setting. Data were collected at two campgrounds in Chiri-Mountain National Park, Korea, in 1993 and 1994. Results showed that a high proportion of users could specify norms for various types of campground impacts. Users who rated high importance on impacts tended to show a higher level of norm prevalence. Generally there were differences in social norms and norm agreement across locations. Among those impacts that showed differences, social norms in a less developed area were more restrictive and norm agreement was higher. The results of this study are consistent with normative studies conducted in North America, suggesting that a normative approach can be applied in a variety of settings. Social norms for selected impact indicators were also stable over a one-year time period. Implications are discussed.KEY WORDS: Norms; Norm prevalence; Norm agreement; Norm stability     

Understanding Conceptual Climate Change Meanings and Preferences of Multi-Actor Professional Leadership in New York

This article sets out to evaluate the range of meanings and preferences for the concepts of adaptation, resilience, mitigation and coping of a variety of professionals in New York who are undertaking leadership positions in developing climate change policies and practices. This article positions a normative set of simplified meanings for each of the aforementioned concepts based on a review of existing literature. Utilizing a survey, these normative meanings are evaluated by and between the: (a) concepts and meanings; (b) concepts and applications and (c) applications and preferences, as applied to various risk-based scenarios ranging from sea-level rise to heat waves. This survey tests the hypotheses that the respondents: (i) are unable to consistently match the concept of resiliency with the normative meanings or applications: and (ii) will not consistently show a preference for resilience applications or outcomes ahead of other concepts. The results of the survey confirm both hypotheses, which is demonstrative of the inadequacy of the current framework dominated by a narrowly defined framework for resilience. It is anticipated that the results of this article will advance an argument for the necessity to develop consistent meanings for concepts which bridge the scientific, policy and popular domains.     

Plant Diversity in Live Fences and Pastures,Two Examples from the Mexican Humid Tropics

This study analyzes the potential uses of live fences and pastures as reservoirs of plant diversity for two regions with different management histories, Los Tuxtlas (LT) and Uxpanapa (UX), Veracruz, México. We studied two habitats, live fences and pastures, analyzed their species richness, diversity, structure and plant composition and classified species according to plant regeneration modes (light-demanding and shade tolerant), seed dispersal syndrome and their local uses. We recorded 62 species of trees at LT and 48 at UX. Live fences were more diverse than pastures in both regions. The LT site showed to analyze the relationship a higher diversity of plants in regeneration stages than the one at UX. However, UX had higher diversity of adult plants in the pastures than LT. Composition and structure of live fences were different between regions, as well as within live fences and pastures, 53 % of species were light-demanding and 40 % were shade tolerant; 70 % of the species were dispersed by birds. Differences between sites are associated with the modifications in live fences structure, which changed according to managerial practices and the use of local species; this may influence plant regeneration modes as well as the visits of avian dispersal agents. In LT, all species found in live fences were useful to humans, whereas in UX, less than half were used by the local population. Our results underline the importance of live fences and isolated trees in pasture habitats as potential sites to host native and useful species from tropical rain forests in livestock landscapes.     

我国开展政策环评的必要性及其基本框架研究

政策环评对决策科学化和民主化具有重要意义，我国2014年修订的《环境保护法》也为开展政策环评提供了一定法律依据。然而，由于我国政治体制和决策模式与西方国家明显不同，政策环评不能照搬国外模式，必须基于自身国情探索中国模式。为此，本文对国际上比较有代表性的政策环评实践进行了总结，对我国开展政策环评的必要性进行了分析，并探讨了我国开展政策环评需要考虑的关键问题，包括政策环评的目的、对象、重点和程序等。具体而言，对于实施政策环评的目的，可表述为健全决策机制、促进环境公平和凝聚社会共识三个方面；对于评价对象，在广义上可包含目前环境影响评价法尚未覆盖的所有高层次决策，在狭义上可将政府部门制定的行政法规、规章和规范性文件等作为重点；对于评价重点，建议整合"以影响为核心"的战略环评和"以制度为核心"的战略环评两种类型的优点，兼顾影响评价和制度评价；对于评价程序，政策环评应基于完全理性决策模式，与政策过程充分融合，在不同阶段分别发挥不同作用。     

Quantifying Outdoor Water Consumption of Urban Land Use/Land Cover: Sensitivity to Drought

Outdoor water use is a key component in arid city water systems for achieving sustainable water use and ensuring water security. Using evapotranspiration (ET) calculations as a proxy for outdoor water consumption, the objectives of this research are to quantify outdoor water consumption of different land use and land cover types, and compare the spatio-temporal variation in water consumption between drought and wet years. An energy balance model was applied to Landsat 5 TM time series images to estimate daily and seasonal ET for the Central Arizona Phoenix Long-Term Ecological Research region (CAP-LTER). Modeled ET estimations were correlated with water use data in 49 parks within CAP-LTER and showed good agreement (r ² = 0.77), indicating model effectiveness to capture the variations across park water consumption. Seasonally, active agriculture shows high ET (>500 mm) for both wet and dry conditions, while the desert and urban land cover types experienced lower ET during drought (<300 mm). Within urban locales of CAP-LTER, xeric neighborhoods show significant differences from year to year, while mesic neighborhoods retain their ET values (400–500 mm) during drought, implying considerable use of irrigation to sustain their greenness. Considering the potentially limiting water availability of this region in the future due to large population increases and the threat of a warming and drying climate, maintaining large water-consuming, irrigated landscapes challenges sustainable practices of water conservation and the need to provide amenities of this desert area for enhancing quality of life.     

Application of response surface methodology for the optimization of biodiesel production from yellow mustard (Sinapis alba L.) seed oil

In the present study, response surface methodology (RSM) involving central composite design (CCD) was applied to optimize the reaction parameters of biodiesel production from yellow mustard (Sinapis alba L.) seed oil during the single-step transesterification process. A total of 30 experiments were designed and performed to determine under the effects of variables on the biodiesel yield such as methanol to oil molar ratio (2:1–10:1), catalyst concentration (0.2–1.0 wt.% NaOH), reaction temperature (50–70°C), and reaction time (30–90 min). The second order polynomial model was used to predict the biodiesel yield and coefficient of determination (R²) was found to be at 0.9818. The optimum biodiesel yield was calculated as 96.695% from the model with the following reaction conditions: 7.41:1 of methanol to oil molar ratio, 0.63 wt. % NaOH of catalyst concentration, 61.84°C of reaction temperature, and 62.12 min of reaction time. It is seen that the regression model results were in agreement with the experimental data. The results showed that RSM is a suitable statistical technique for optimizing the reaction parameters in the transesterification process in order to maximize the biodiesel yield.     

Whose voices count in biodiversity conservation? Ecological democracy in biodiversity offsetting,REDD+, and rewilding

ABSTRACT

Ecological democracy seeks environmentally sustainable ends through broad, active democratic participation. What happens when laws fostering participation in environmental decision-making and biodiversity preservation lead to differing results? What is best for biodiversity may not be what for local citizens believe is best. I examine conflicts and congruencies in the context of Biodiversity Offsetting, REDD+ (Reducing Emissions from Deforestation and forest Degradation), and the Rewilding movement. I ask questions that are legal (Who has what legal rights to speak for or against programs that enhance biodiversity?), epistemological (Whose expertise and knowledge matters when scientists and non-scientists don't agree?), axiological (Are some values objectively better, and why?), and normative (Whose opinions about biodiversity should count?). Many people have the right to participate in an ecological democracy: But when protecting biodiversity, who does and should have the right to be heard? I problematize the role that ‘local’ actors play in decision-making and describe the variegated role that experts – particularly biologists – play in ecological democracy when biodiversity preservation matters. To determine whose values and voices should be prioritized, I describe ‘deep equity,’ an axiological and normative groundwork for determining when biodiversity-promoting policies may be preferable even if affected citizens don't agree.     

Vegetation Response to Western Juniper Slash Treatments

The expansion of piñon–juniper woodlands the past 100 years in the western United States has resulted in large scale efforts to kill trees and recover sagebrush steppe rangelands. It is important to evaluate vegetation recovery following woodland control to develop best management practices. In this study, we compared two fuel reduction treatments and a cut-and-leave (CUT) treatment used to control western juniper (Juniperus occidentalis spp. occidentalis Hook.) of the northwestern United States. Treatments were; CUT, cut-and-broadcast burn (BURN), and cut-pile-and-burn the pile (PILE). A randomized complete block design was used with five replicates of each treatment located in a curl leaf mahogany (Cercocarpus ledifolius Nutt. ex Torr. & A. Gray)/mountain big sagebrush (Artemisia tridentata Nutt. spp. vaseyana (Rydb.) Beetle)/Idaho fescue (Festuca idahoensis Elmer) association. In 2010, 4 years after tree control the cover of perennial grasses (PG) [Sandberg’s bluegrass (Poa secunda J. Pres) and large bunchgrasses] were about 4 and 5 % less, respectively, in the BURN (7.1 ± 0.6 %) than the PILE (11.4 ± 2.3 %) and CUT (12.4 ± 1.7 %) treatments (P < 0.0015). In 2010, cover of invasive cheatgrass (Bromus tectorum L.) was greater in the BURN (6.3 ± 1.0 %) and was 50 and 100 % greater than PILE and CUT treatments, respectively. However, the increase in perennial bunchgrass density and cover, despite cheatgrass in the BURN treatment, mean it unlikely that cheatgrass will persist as a major understory component. In the CUT treatment mahogany cover increased 12.5 % and density increased in from 172 ± 25 to 404 ± 123 trees/ha. Burning, killed most or all of the adult mahogany, and mahogany recovery consisted of 100 and 67 % seedlings in the PILE and BURN treatments, respectively. After treatment, juniper presence from untreated small trees (<1 m tall; PILE and CUT treatments) and seedling emergence (all treatments) represented 25–33 % of pre-treatment tree density. To maintain recovery of herbaceous, shrub, and mahogany species additional control of reestablished juniper will be necessary.     

STATUS REPORT ON HEAT STORAGE WELLS1

ABSTRACT. The Heat Storage Well concept evolved at TEMPO in 1972. Technical, economic, institutional, and legal aspects of implementing the concept are being studied. Heat Storage Wells offer the possibility of conserving a substantial part of the heat energy now wasted in generating electricity and of reducing thermal pollution caused by the waste heat. Large thermal electric power plants would produce heat at useful temperatures such as 300–400°F. Combined electric- and heat-generating systems will require low-cost, low-loss storage of large amounts of hot water for periods of 90 to 180 days to serve both electric loads and seasonally-varying heat loads. Compared to conventional electricity-only systems, combined electricity-heat systems can save more than 20 percent in energy, reduce the cost of both electricity and heat, and eliminate the need for cooling water or towers. Possibilities for changes in legal and institutional practices are suggested, such as making resource-allocation decisions on the basis of energy units rather than dollars.     

Property rights and governance of Africa's rangelands: A policy overview

Recent efforts at securing property rights in dryland Africa have generally involved several interrelated processes such as legal and policy reforms that recognize and strengthen customary rights or the seasonal rights of pastoralists, and the decentralization of land allocation and administration to lower governance levels. These solutions are in turn beset by new problems, key among them are establishing norms for local participation in decision making, preventing manipulation and capture by elites, lack of accountability of local level institutions and authorities, and the onset of a new generation of resource user conflicts. Increasing avenues through which dialogue and communication can occur among policy actors (including local communities) in order to mobilize multiple experiences, information, and to manage power relationships — a collaborative approach to policy governance — is one way of approaching the complexity paradox. This is anticipated to provide opportunity for learning, innovation and adaptability.
