Determinants of Farmers’ Adoption of Improved Soil Conservation Technology in a Middle Mountain Watershed of Central Nepal

This study explores different socio-economic and institutional factors influencing the adoption of improved soil conservation technology (ISCT) on Bari land (Rainfed outward sloping terraces) in the Middle Mountain region of Central Nepal. Structured questionnaire survey and focus group discussion methods were applied to collect the necessary information from farm households. The logistic regression model predicted seven factors influencing the adoption of improved soil conservation technology in the study area including years of schooling of the household head, caste of the respondent, land holding size of the Bari land, cash crop vegetable farming, family member occupation in off farm sector, membership of the Conservation and Development Groups, and use of credit. The study showed that technology dissemination through multi-sectoral type community based local groups is a good option to enhance the adoption of improved soil conservation technology in the Middle Mountain farming systems in Nepal. Planners and policy makers should formulate appropriate policies and programs considering the farmers' interest, capacity, and limitation in promoting improved soil conservation technology for greater acceptance and adoption by the farmers.     

Possible Input of Nitrogen of Visitors’ Origin on a Protected Peatland

The Ozegahara peatland, in the Nikko-Oze National Park in Japan, is ecologically significant because of its oligotrophic environment; it is one of the most strictly preserved areas in the country. The isotope ratio of nitrogen (¹⁵N/¹⁴N) and carbon (¹³C/¹²C) and C/N ratio of peat moss (Sphagnum spp.) and sundew (Drosera rotundifolia) in the peatland were analyzed. The correlation of the isotope ratio with some parameters (sundew population density, number of trapped insects, water level, bog myrtle coverage, and visitor density) was investigated. The nitrogen isotope ratio of sundew showed the most significant covariation with visitor density, where sundew from lunch areas or along busy walkways showed a higher nitrogen isotope ratio. The nitrogen isotope ratio of peat moss covaried, not only with route traffic frequency but also with water level, bog myrtle coverage, and number of trapped insects by sundew, indicating that factors other than the visitor level influence the local nitrogen cycle. This study suggests that the nitrogen imported into the peatland by visitors is a principal factor to be monitored for the maintenance of the natural environment.     

Effects of observability and complexity on farmers’ adoption of environmental practices

The ability of both regulators and farmers themselves to monitor the impact of environmental practices may be an issue with nonpoint source pollution. Effects that can be perceived via direct sensory evidence provide information at low cost. Results from a survey of livestock farmers suggest that a practice that has more obvious effects on water quality, manure application setbacks, is more likely to be adopted than a more complicated one with less visible effects, manure testing. Farmers’ perceptions of the profitability of the two practices were similar. The importance of observability and complexity has implications for educational programs.     

Analysis of Scavengers’ Activities and Recycling in Some Cities of Nigeria

The state of solid waste recycling by scavengers in Onitsha, a heavily commercial city in Anambra State, and some other urban areas such as Nsukka, Enugu, and Port Harcourt was analyzed. Data were obtained through interviews of scavengers who deal with recyclables. Although the activities of scavengers are sub-optimal, they can have a great impact on Nigerian economy with respect to resource conservation, creation of job opportunities, and reduction of the magnitude of waste disposal problems. A cost analysis is presented to compare the different forms of recycling utilized by municipal solid waste management. It is shown that a well-planned recycling program with recycling and composting would result in 18.6% savings in waste management costs and 57.7% in landfill avoidance costs. However, if the compost materials are not recycled, the corresponding savings in cost become 8.6% and 28.6%, respectively. The option with the lowest cost involves encouraging individual households to separate at the source their recyclables, which are bought by scavengers. This results in 78.0% savings in waste management cost and 79.5% landfill avoidance cost. A low-cost approach aimed at the integration of scavenging activities into conventional solid waste management is presented.     

“First Things First”: Application of Islamic Principles of Priority in the Ethical Assessment of Genetically Modified Foods

Advancement of modern agricultural biotechnology has brought various potential benefits to humankind, but at the same time ethical concerns regarding some applications such as genetically modified foods (GMF) have been raised among the public. Several questions are being posed; should they utilize such applications to improve quality of their life, or should they refrain in order to save themselves from any associated risk? What are the ethical principles that can be applied to assess these applications? By using GMF as a case study, this paper discusses possible answers to these questions from Islamic perspective. Such answers are based on the understanding of the Islamic concept of maslahah (benefit) and mafsadah (harm) as well as the Islamic principles of priority. There is no specific GMF that has been declared as unlawful by Muslim scholars thus far. Nevertheless, they generally state that any GMF that contains unlawful substance is prohibited in Islam. Such statement can be understood since Islam puts highest priority to preserve shari’ah (Islamic law) which prescribes the lawful and unlawful things in human life. Priorities have also been given to preserve human health and environment therefore any GMF that may inflict harm on both entities is also considered as unlawful.     

Is there a correct way of establishing sustainability indicators? The case of sustainability indicator development on the Island of Guernsey

Abstract

The popularity of sustainability indicators is almost inescapable. From the early pioneers such as the ‘Sustainable Seattle’ project (Atkisson, ‘Developing Indicators of a Sustainable Community: lessons from Sustainable Seattle’, in: D. Satterthwaite (Ed), The Earthscan Reader in Sustainable Cities, London, Earthscan, 1996) to the comprehensive European Union benchmarking launched in 2003 (European Commission, European Common Indicators: towards a local sustainability profile, Milan, Ambiente Italia, 2003), it seems that consensus has been reached about the positive impacts that establishing sustainability indicators can bring. This paper uses the case of developing sustainability indicators on the Island of Guernsey over the last three years to show that Agenda 21's call to activate grassroots action is being realised, but in ways that are neither top-down and modernist in approach nor bottom-up and postmodernist as Agenda 21 advocates. Although best practice literature often suggests that community involvement must be engaged prior to designing sustainability indicators, this paper explores the reasons why this is not always possible. Guernsey's case is used to show how it only became possible to generate interest in the indicator process once they were actually up and running. However, it also shows that once interest was secured by a few relevant stakeholders it became possible to further evolve the indicators in a process that has slowly been attracting more and more of the Island's community.     

Application of Zoning and “Limits of Acceptable Change” to Manage Snorkelling Tourism

Zoning and applying Limits of Acceptable Change (LAC) are two promising strategies for managing tourism in Marine Protected Areas (MPAs). Typically, these management strategies require the collection and integration of ecological and socioeconomic data. This problem is illustrated by a case study of Koh Chang National Marine Park, Thailand. Biophysical surveys assessed coral communities in the MPA to derive indices of reef diversity and vulnerability. Social surveys assessed visitor perceptions and satisfaction with conditions encountered on snorkelling tours. Notably, increased coral mortality caused a significant decrease in visitor satisfaction. The two studies were integrated to prescribe zoning and “Limits of Acceptable Change” (LAC). As a biophysical indicator, the data suggest a LAC value of 0.35 for the coral mortality index. As a social indicator, the data suggest that a significant fraction of visitors would find a LAC value of under 30 snorkellers per site as acceptable. The draft zoning plan prescribed four different types of zones: (I) a Conservation Zone with no access apart from monitoring or research; (II) Tourism Zones with high tourism intensities at less vulnerable reefs; (III) Ecotourism zones with a social LAC standard of <30 snorkellers per site, and (IV) General Use Zones to meet local artisanal fishery needs. This study illustrates how ecological and socioeconomic field studies in MPAs can be integrated to craft zoning plans addressing multiple objectives.     

Are mere instructions enough? Evaluation of four types of messaging on community depot recycling

Curbside recycling efforts have made an important contribution to waste containment, but many communities have specific limitations on what products can be recycled within their community bins (e.g., no cartons, styrofoam, soft plastics) and must rely on depots for recycling these other items. These specialty depots typically take the form of local community or large central municipal sites. The purpose of this randomized trial was to examine messages targeting (1) awareness/instructions, (2) utility, (3) affect, and (4) planning upon community and central depot recycling across eight weeks. One hundred and seventy-six community-dwelling residents between the ages of 18–65 years who self-identified as having the potential to improve their depot recycling activities completed baseline recycling measures and then were randomly assigned to one of the four messaging conditions. One hundred and forty-four of these participants subsequently answered follow-up recycling behavior measures four and eight weeks later. Intention to treat analyses showed that depot recycling increased significantly from baseline to four weeks. The effect waned for community recycling while holding for municipal depot recycling at eight weeks. Distance to recycling depot (closer proximity resulted in greater community recycling), access to a car (low access resulted in greater community recycling), and baseline recycling behavior (no prior recycling resulted in greater behavior change) all acted as significant moderators of the effect. There was no time by group interaction among conditions. The findings support the use of basic instructions – as a minimum – for promoting depot recycling efforts and provide evidence that local community depots, in conjunction with municipal depots, are important to increasing recycling behavior.     

The Politics of Waste Incineration in Beijing: The Limits of a Top-Down Approach?

The siting of waste incinerators is often a highly contentious issue. Although most studies have focused on Western countries, municipal solid waste management has become an extremely pressing issue in China. Incineration is being strongly promoted by government officials, yet this has resulted in strong societal opposition. Through documentary analysis and in-depth stakeholder interviews, this article analyses three anti-incineration campaigns in Beijing, focusing on outcomes and campaigner strategies. Anti-incineration campaigns have partly undermined the government's top-down, non-consultative approach to waste management. In developing an ‘expert strategy’, campaigners have exploited government weakness whilst depoliticizing the issue. Yet rather than lead to a more open and consultative incineration policy, it is more likely that officials will circumvent unrest through increasing opacity and by choosing sites in locations where opposition is less likely to emerge.     

What Lies Beneath? An Evaluation of Rapid Assessment Tools for Management of Hull Fouling

Despite an increased understanding of marine invasions, non-indigenous species (NIS) continue to be redistributed at both global and regional scales. Since prevention is an important element of NIS programs, monitoring vectors responsible for NIS introductions and spread, such as hull fouling, has become a priority and methods should be selected carefully to balance accuracy, time, and cost. Two common fouling assessment tools for the marine recreational boating vector were evaluated for accuracy using a traditional underwater SCUBA survey in coastal British Columbia: a dockside level of fouling assessment and a behavioral questionnaire model. Results showed that although rapid, dockside assessments did not provide an accurate assessment of fouling present below the surface, at least not in this region. In contrast, a questionnaire-based model using four easily obtained variables (boat type, age of antifouling paint, storage type, and occurrence of long distance trips) reliably identified boats carrying macrofouling species, a proxy for risk of NIS transport. Once validated, this fouling model tool could be applied in border inspection or quarantine situations where decisions must be made quickly. Further development and refinement of rapid assessment tools would improve our ability to prevent new introductions and manage spread of existing invasive species.     

Partial neutralization of rain by seaspray: the case of Recôncavo, Bahia-Brazil

In the Recôncavo of Bahia (located between 12°33′ and 13°10′S and 38°00′and 39°00′W), there are significant discharges of SO₂ and NO_x due to local, industrial and urban activities. The incoming air masses from the Atlantic Ocean are enriched with seaspray, which neutralizes part of the rain acidity. The extent of seaspray neutralization of rain acidity was quantified in four sites of the region, each with different loads of seaspray. Rain samples were obtained daily at the same time, integrating the precipitation of the previous 24 h, using wet-only collectors and analyzed for pH by potentiometry and for sodium by flame photometry. The amount of rain acidity in Recôncavo neutralized by seaspray ranged from <1% up to 88% and depended on the site. On average, neutralization ranged from 5% to 18%.     

The supervision of environmental risk: The case of HCB waste or Botany/Randwick?

The governance activities of capital and the state include attempts to control the timing and spacing of social activities such as the production of environmental risks and settlement of different social groups. The supervisory activities that have shaped the environmental and social history of the Botany/Randwick area are identified here, to examine how the HCB waste risk developed in that community. The analysis shows that multiple environmental risks and an ethnically diverse, working class community have been brought together in space to create environmental injustice. Analysing the governance of one environmental risk like hexachlorobenzene (HCB) waste may not increase understanding about communities facing multiple environmental risks or the supervisory processes that lead to the unfair accumulation of risks for particular places or social groups. Lessons from the environmental justice movement suggest that reframing problems like HCB waste management at Botany/Randwick as distributive justice issues may contribute to governance arrangements that better manage multiple risks and pollution sources in space affecting marginalised communities.     

Are two resources really better than one? Some unexpected results of the availability of substitutes

The possibility of exploiting multiple resources is usually regarded as positive from both the economic and the environmental point of view. However, resource switching may also lead to unsustainable growth and, ultimately, to an equilibrium condition which is worse than the one that could have been achieved with a single resource. We developed a dynamic model where users exploit multiple resources and have different levels of preference among them. In this setting, exploiting multiple resources leads to worse outcomes in both economic and ecological terms than the single resource case under a wide range of parameter configurations. Our arguments are illustrated using two empirical situations, namely oil drilling in the North Sea and whale hunting in the Antarctic.     

Who Cares about Farmed Fish? Citizen Perceptions of the Welfare and the Mental Abilities of Fish

This paper explores citizens’ views about the welfare of farmed fish and the mental abilities of fish with a large survey data sample from Finland (n = 1,890). Although studies on attitudes towards animal welfare have been increasing, fish welfare has received only limited empirical attention, despite the rapid expansion of aquaculture sector. The results show that the welfare of farmed fish is not any great concern in the Finnish society. The analysis confirms the distinct character given to farmed fish compared to traditional farmed animals. Salmon are rated low in their mental abilities, including the capacity to feel pain, which may weaken ethical concerns for fish welfare. When analyzing the social determinants surrounding the rating of the welfare of farmed fish, it was shown that fish welfare attitudes follow general animal welfare attitudes regarding age and place of residence as fish welfare tends to be rated more negatively among younger age groups and among urban residents. However, no clear connection could be identified between gender and the rating of fish welfare, which may suggest that the distinct cultural categorization of fish diminishes the typical gender difference identified in animal attitudes. It is concluded that in order to improve awareness about fish welfare, there is a need to increase dissemination of scientific knowledge about fish and their welfare. Moreover, further research should be directed toward studying the moral positioning of fish and the distinct moral categorization they receive.     

The Right Tree for the Job? Perceptions of Species Suitability for the Provision of Ecosystem Services

Stakeholders in plantation forestry are increasingly aware of the importance of the ecosystem services and non-market values associated with forests. In New Zealand, there is significant interest in establishing species other than Pinus radiata D. Don (the dominant plantation species) in the belief that alternative species are better suited to deliver these services. Significant risk is associated with this position as there is little objective data to support these views. To identify which species were likely to be planted to deliver ecosystem services, a survey was distributed to examine stakeholder perceptions. Stakeholders were asked which of 15 tree attributes contributed to the provision of five ecosystem services (amenity value, bioenergy production, carbon capture, the diversity of native habitat, and erosion control/water quality) and to identify which of 22 candidate tree species possessed those attributes. These data were combined to identify the species perceived most suitable for the delivery of each ecosystem service. Sequoia sempervirens (D.Don) Endl. closely matched the stakeholder derived ideotypes associated with all five ecosystem services. Comparisons to data from growth, physiological and ecological studies demonstrated that many of the opinions held by stakeholders were inaccurate, leading to erroneous assumptions regarding the suitability of most candidate species. Stakeholder perceptions substantially influence tree species selection, and plantations established on the basis of inaccurate opinions are unlikely to deliver the desired outcomes. Attitudinal surveys associated with engagement campaigns are essential to improve stakeholder knowledge, advancing the development of fit-for-purpose forest management that provides the required ecosystem services.     

The Edge of “Animal Rights”

A central task of environmental ethics, which have been arising since 1960s, is to extend the objects of moral concern beyond the individuals of Homo sapiens. (Here, it involves the issue of the boundary of environmental ethics. In a narrow sense, an environmental ethic must grant moral concern to holistic environmental objects (such as ecosystems). On the other hand, if we broadly define the environmental ethic as an ethic that shows moral concern not limited to Homo sapiens and its individuals only, then, these “generalized” environmental ethics include Peter Singer’s “animal liberation” and Tom Regan’s “animal rights”. In this article, the term “environmental ethic” refers to an environmental ethic in a generalized sense.) All the objects deserving moral concern constitute the moral community. The trajectory and boundary of this extension are different among different schools. Compared to other schools, Tom Regan’s “animal rights” has a relatively smaller moral community, making it more “conservative” at first sight. Meanwhile, the rights view, like other schools, faces the question regarding the edge of moral concern. This question consists of two sub-questions: (1) where is the boundary of the moral community and (2) how ought we to treat the objects of moral concern near the boundary? Given the closeness of Regan’s theory to traditional ethics (regarding the boundary of the moral community), this study is mainly focused on analyzing the edge of moral concern within the framework of the theory of animal rights. Further, I investigate the similarities and differences in the boundary of moral concern among various schools of environmental ethics. The comparative analysis demonstrates a subtle relation between science and moral philosophy, and reveals a similar form of a metaphysical premise adopted by all environmental ethics. This research helps to clarify the moral concern of environmental ethics, which is an essential prerequisite for establishing a new ethic, and therefore helps to consolidate the reference of environmental ethics to environmental management.     

Benefit–Cost Analysis of StormwaterQuality Improvements

The major purpose of this paper is to explore the potential value of benefit–cost evaluation for stormwater quality management decisions at a local level. A preliminary benefit–cost analysis (BCA) screening method is used for maximum extent practicable (MEP) analysis, identifying promising management practices, and identifying societal and economic tradeoffs for local stormwater problems. Ballona Creek, a major urban storm drain in Los Angeles, California, USA, is used to illustrate the practicality of the benefit–cost evaluation. The Ballona Creek example demonstrates the economic limits of stormwater management in an urban region and attests to the value of coordinated basinwide management compared to uncoordinated management by individual landowners. Evaluation results suggest that in urban areas, the benefit of stormwater quality improvements might be far greater if accompanied by comprehensive redesign of drainage networks and neighboring land uses. In this case, benefit–cost analysis is found to be useful for evaluating and understanding stormwater management alternatives despite the uncertainties in characterizing stormwater quality and the effects of stormwater management on improving receiving water quality.     

Shades of blue: what do competing interpretations of the Blue Economy mean for oceans governance?

The ‘Blue Economy’ is an increasingly popular term in modern marine and ocean governance. The concept seeks to marry ocean-based development opportunities with environmental stewardship and protection. Yet different actors are co-opting this term in competing, and often conflicting ways. Four conceptual interpretations of the Blue Economy are identified, through examination of dominant discourses within international Blue Economy policy documents and key ‘grey’ literature. The way the Blue Economy is enacted is also examined, through an analysis of the Blue Economy ‘in practice’, and the actors involved. Finally, the scope of the Blue Economy is explored, with a particular focus on which particular marine industries are included or excluded from different conceptualizations. This analysis reveals areas of both consensus and conflict. Areas of consensus reflect the growing trend towards commodification and valuation of nature, the designation and delimitation of spatial boundaries in the oceans and increasing securitization of the world's oceans. Areas of conflict exist most notably around a divergence in opinions over the legitimacy of individual sectors as components of the ‘Blue Economy’, in particular, carbon-intensive industries like oil and gas, and the emerging industry of deep seabed mining.
