Social contrasts and land use conflicts in the context of sustainable development and management needs: a case study from an estuarine area at northeastern Brazil

This paper discusses the misuses of estuaries in Northeast of Brazil and the social contrasts there found. The several kinds of impacts promoted by capitalist enterprises in one side and by traditional population, who uses estuary areas at another side, are in complete disagreement with the ethic of sustainable development. Our intention is to demonstrate how these aspects occur in the River Paraíba do Norte estuary, in the State of Paraíba. Observing the conditions of infrastructure besides the multiple ways to handle along with the extension of the estuary, we could recognize 59 focus of conflict between the incorrect use and sustainable mode. Most of the uses concern to traditional artisan fishing, slums and recreational marinas, reflecting the great social contrast between rich and poor people settled in area studied. Ecological and social implications of these conflicting uses are discussed and measures to improve the situation are suggested.     

Ethnobotany in Cabo Delgado, Mozambique: Use of Medicinal Plants

Communities in Cabo Delgado have a long tradition of using medicinal plants. In Mozambique, rural populations in general are highly dependent on natural resources. One example is the use of surrounding vegetation by people from Cabo Delgado. They use plants for food, handicrafts, construction, as a primary energy source and even for medicine purposes. In this survey, we examined the diversity of plant usage for medicinal purposes by 146 individuals, including adults and youth living in the Cabo Delgado province. This community quoted 16 species of plants, belonging to 13 families. Utilisation by different categories of people based on sex and age was compared and differences were found among some groups. In general, older people show a deeper knowledge of medicinal plants than younger people. Men and women show similar knowledge of medicinal plants.     

Green economy: Private sectors’ response to climate change

The focus of this paper is to present a discussion of the role of the private sector in response to the need for climate change adaptations. The study, which was conducted through a literature review, investigates the concept of the green economy and climate change, as well as businesses’ commitment to advance climate actions in ways that build resilience in vulnerable communities in developing countries. The paper calls on companies with national, regional, and/or global reach to adopt or develop strategies that improve resource efficiency, reduce greenhouse gas emissions, and reduce the loss of biodiversity. Businesses can accelerate this transition by aligning their investments with climate change adaptation opportunities, and thus, “green” the economy. In addition, green growth could be achieved through tactical public and private investments in mitigating climate change. The paper concludes that the private sector is a key sector in addressing the challenges of vulnerable communities, and it has much to contribute to the planning, development, and implementation of climate adaptation strategies, including sector‐specific expertise, technology, efficiency, financing, and entrepreneurship. Finally, some social conditions and environmental boundaries have been highlighted in this paper to attract the attention of business leaders who are trying to build initiatives and advance climate actions that will reduce socio‐community risks from climate change. Also, comprehensive initiatives and strategies have been recommended to private companies seeking to address climate vulnerabilities.     

Place attachment as a driver of adaptation in coastal communities in Northern Norway

Changes in a range of interlinked factors, in social, economic, environmental and climatic conditions, require adaptation in many communities. This paper explores how place attachment affects adaptive responses to a changing social context through analysing adaptation in two coastal municipalities in Northern Norway. The main challenge in these municipalities is declining populations and the consequences accompanying this trend, including livelihood uncertainties and decreased provision of public services. This paper discusses the role of place attachment in motivating adaptation to these changes to contribute to a growing body of literature within climate change adaptation on “subjective” (values, culture and place) dimensions. The findings suggest that people are motivated to act based on their emotional connection with place, and the paper argues that place attachment may offer a better starting point for climate change adaptation than an emphasis on climate change impacts.     

Tracing the unintended consequences of food safety regulations for community food security and sustainability: small-scale meat processing in British Columbia

In 2004, as a response to the discovery of Bovine Spongiform Encephalopathy in Canadian cattle and other food scares, the Province of British Columbia (BC) developed a comprehensive set of meat inspection regulations, increasing the requirements for food safety infrastructure. Through a series of interviews with farmers and stakeholders, we highlight some of the unintended consequences for community food security and sustainability that resulted from these stringent safety regulations in rural and remote communities in BC. These include the loss of meat production and processing capacities as well as the erosion of local food practices and traditions through the criminalisation of farm-gate sales. We suggest that food safety regulations intended to protect consumer health may result in negative effects for community food security and rural sustainability and that these consequences should be accounted for when developing food policy.     

Meeting the climate change challenge: a scan of greenhouse gas emissions in BC communities

The Canadian province of British Columbia (BC) is taking significant steps towards climate change mitigation, including a carbon tax on fossil fuels and legislation that mandates greenhouse gas (GHG) reductions within public sector organisations and GHG reduction targets for municipalities. This paper carries out a preliminary scan of the GHG emissions of BC communities using the provincially mandated Community Energy and Emissions Inventory reports. We map trends in energy consumption and emissions per capita while uncovering correlations between these variables and land-use planning, geographic, and demographic variables. These data have shown that: (1) energy consumption in BC is an adequate proxy for GHG emissions; (2) transportation, more than buildings, is a strong driver of overall GHG emissions; (3) building emissions are not likely to be strongly influenced by dwelling type, but density of buildings is crucial; (4) geographic location influences emissions; and (5) population size and age do not appear to influence per capita emissions. These findings are particularly important as they suggest that the potentially intransigent factors of income and population size need not be barriers to achieving significant GHG reductions. The policy onus thus falls squarely on transportation planning, land-use, energy conservation, and fuel switching. This in turn highlights the importance of deeper underlying sociocultural and political preferences, which shape the behaviours that have a strong bearing on emissions profiles.     

Monitoring bioaccumulation and toxic e ects of hexachlorobenzene using the polyurethane foam unit method in the microbial communities of the Fuhe River,Wuhan

Hexachlorobenzene （HCB） is a chlorinated aromatic hydrocarbon that was widely used for seed dressing in prevention of fungal growth on crops, and also as a component of fireworks, ammunition, and synthetic rubbers. Because of its resistance to degradation and mobility, HCB is widely distributed throughout the environment and is accumulated through food chains in different ecosystems. In this study, a preliminary investigation was carried out on the bioaccumulation and the toxic effects of HCB in the microbial （protozoan in particular） communities in the Fuhe River, Wuhan, a water body receiving industrial wastewaters containing HCB and other pollutants, using the standardized polyurethane foam units （PFU） method. Field samples were taken from eight stations established along the Fuhe River in January and August 2006. The concentration ratios of HCB in microbial communities and in water were 9.66-18.64, and the microbial communities accumulated 13.29-56.88 μg/L of HCB in January and 0.82-10.25 μg/L HCB in August. Correlation analysis showed a negative correlation between the HCB contents in the microbial assemblage, and the number of species and the diversity index of the protozoan communities. This study demonstrated the applicability of the PFU method in monitoring the effects of HCB on the level of microbial communities.     

Can the green economy enhance sustainable mountain development? The potential role of awareness building

Mountain socio-ecological systems produce valuable but complex ecosystem services resulting from biomes stratified by altitude and gravity. These systems are often managed and shaped by smallholders whose marginalization is exacerbated by uncertainties and a lack of policy attention. Human–environment interfaces in mountains hence require holistic policies. We analyse the potential of the Global Mountain Green Economy Agenda (GMGEA) in building awareness and thus prompting cross-sectoral policy strategies for sustainable mountain development. Considering the critique of the green economy presented at the Rio + 20 conference, we argue that the GMGEA can nevertheless structure knowledge and inform regional institutions about the complexity of mountain socio-ecological systems, a necessary pre-condition to prompt inter-agency collaboration and cross-sectoral policy formulation. After reviewing the content of the GMGEA, we draw on two empirical cases in the Pakistani and Nepali Himalayas. First, we show that lack of awareness has led to a sequence of fragmented interventions with unanticipated, and unwanted, consequences for communities. Second, using a green economy lens, we show how fragmentation could have been avoided and cross-sectoral policies yielded more beneficial results. Project fragmentation reflects disconnected or layered policies by government agencies, which inherently keep specialized agendas and have no incentive to collaborate. Awareness makes agencies more likely to collaborate and adopt cross-sectoral approaches, allowing them to target more beneficiaries, be more visible, and raise more funds. Nevertheless, we also identify four factors that may currently still limit the effect of the GMGEA: high costs of inter-agency collaboration, lack of legitimacy of the green economy, insufficiently-secured smallholder participation, and limited understanding of the mechanisms through which global agendas influence local policy.     

Environmental, cultural, economic and socio-community sustainability: a framework for sustainable tourism in resort destinations

This paper utilizes an inclusive community based sustainability framework with a focus on a resort destination in providing a potential model for more inclusive long-range destination planning and implementation. Four diverse, but interrelated areas of sustainable tourism were specified in this framework for a more comprehensive process including ecological, cultural, economic and socio-community sustainability. In addition a strategic community driven structure, which provides direction, information and practices, serves the purpose of integrating and implementing the framework. The unique tourism destination, Noosa in Australia is used as an example of embracing sustainable tourism as a community and as part of a larger focus on the four key components of sustainability. By viewing sustainable community attributes as assets, all of which are important to manage, enhance and/or conserve, it is expected that the resort community will continue to attract visitors to feel connected and committed to experiencing its lifestyle, sense-of-community and natural features while also contributing to community sustainable stewardship and a strong tourism economy.
