The theory of neighbourhood decline due to pariah land uses: Regaining control of the downward cycle

Abstract

Some neighbourhood environments have become dumping grounds for locally unwanted land uses (LULUs) that middle-class Americans do not want near their homes. LULUs may combine with other pariah land uses to collectively undermine the quality of the local environment, reduce investment, government services, the proportion of middle-income people and associated businesses. As important neighbourhood attributes are lost, illegal activities, derelict structures, trash-strewn lots and the concentration of poor and unhealthy people may increase. This paper describes the theory behind the impact of pariah land uses through examples of the downward spiral experienced by Camden, New Jersey and the south Bronx, New York. It then documents the experience of one community, Elizabethport, New Jersey, in reversing that downward spiral. Success in Elizabethport came from the synergistic activities of local, state and federal governments, community groups, and not-for-profit organizations as they struggled to regain control through local environmental management, rebuilding, and reducing crime. Social capital was also strengthened by using a local community health concern—that of childhood asthma. Efforts to reverse the downward spiral of urban decay from pariah land uses should be multi-faceted, spurred by local efforts that address local concerns.     

Eliciting preferences for wetland services: a way to manage conflicting land uses

A choice experiment was used to analyse the preferences of residents neighbouring the Erstein polder (Alsace, France) for the different services that it provides. The heterogeneous nature of these preferences was shown through the use of a latent class model. Whilst the population as a whole values the improvement in water quality and the contribution, even partial, to flood protection, preferences differ when it comes to biodiversity and public access to the site. This study shows the potential conflicts between the different uses of the Erstein polder. These conflicts represent different communication themes for the site managers.     

An ecological analysis of predominant land uses in the Brazilian Amazon

Summary The land uses that now predominate in Brazil's Amazon Region are unlikely to produce sustainable yields. They also tend to close off potentially sustainable alternative uses. Cattle pasture — either productive or abandoned — now occupies most deforested land. Small farmers plant pasture after using the land for a year or two under annual crops, while large cattle ranches plant pasture directly after clearing. The principal motive for planting pasture is often its low cost and high effectiveness as a means of securing speculative land claims — not beef production.Pasture and cattle yields are low and, after use for about a decade, the planted grasses are out-competed by secondary forest species or inedible grasses. Depletion of available phosphorus in the soil is a major cause of yield decline; Brazil's relatively modest phosphorus deposits, virtually all of which are outside of Amazonia, make fertiliser use not feasible for the vast areas now rapidly being converted to pasture. Converting a substantial portion of Amazonia to pasture would have potential climatic effects. Areas that can be planted in annual and perennial crops are restrained by world markets, as well as by soil quality and Brazil's limited stocks of the inputs needed for intensive agriculture.Recent initiatives for agricultural-ecological in Brazil's Amaoznian states could be a first step toward more rational land use. Immediate measures are needed to slow deforestation, to discourage unsustainable uses and to make sustainable alternatives profitable.Professor Philip Fearnside is currently Research Professor in the Department of Ecology at the National Institute for Research in the Amazon. The paper has been modified from an earlier version presented at the International Symposium on Alternatives to Deforestation held in Belém, Pará, Brazil in January 1988.     

Application of chaos theory to solving the problems of social and environmental decline in Lesotho

This paper examines the definition of chaos theory and its use in different circumstances. The paper explains that environmental crisis is complex, chaotic and unstable and will remain so unless actions are taken to reverse the trend. It further suggests that chaos theory could be used to interpret the crisis and help identify solutions. By recommending the application of chaos theory to the environmental problems in Lesotho, the paper explores some of the key issues that contribute to and perpetuate the environmental situation, for example, the current land tenure system and the problem of overgrazing. In addition, it identifies appropriate and realistic government policies that could be implemented to address the environmental degradation in the country. The paper concludes that the application of chaos theory may be unable to help solve the environmental crisis in Lesotho unless there is political will and commitment and collective effort from all stakeholders, coupled with an attitudinal change.     

The multifunctionality of urban farming: perceived benefits for neighbourhood improvement

Urban farming – a type of urban agriculture focused on entrepreneurial food production – serves multiple functions in neighbourhoods; yet these are not well delineated. Expectations for urban farming often centre on traditional measures of economic development, potentially overlooking other benefits. Through a qualitative case study conducted in Baltimore, Maryland, we sought to understand community perceptions regarding the ways in which urban farms can benefit cities. Interviews with residents, neighbourhood leaders, and urban farmers in three residential neighbourhoods with urban farms revealed the pathways by which community members view farms as improving neighbourhoods. Benefits stemmed from four primary changes urban farms made to study neighbourhoods: creation of public projects welcoming involvement, physical improvement of degraded space, production of local food, and creation of new businesses. These changes led to multiple perceived benefits including increased social connectedness, a transformed physical landscape, improved neighbourhood reputation, increased access to fresh produce, and educational, youth development, and employment opportunities. Our findings demonstrate the importance of a multifunctional paradigm that accounts for social and educational functions in assessing the value of urban farming and bring empirical evidence to the concept of multifunctional agriculture. Urban farms with strong social aims may appear to contribute little to economic development if measured using traditional indicators of success such as job creation or fiscal impacts, but provide numerous other benefits for community development.     

Farmers' assessment of the social and ecological values of land uses in central highland Ethiopia

Often in land use evaluations, especially those in developing countries, only the financial aspect receives serious attention, while the social and ecological values are overlooked. This study compared the social and ecological values of four land use types (small-scale woodlot [SSW], boundary tree and shrub planting [BTP], homestead tree and shrub growing [HTG] and cereal farming [CF]) by a criteria-based scoring approach using a bao game. The impacts of local wealth status and proximity to a forest on the value the community renders to the land use types were also assessed. The value comparison, assessed by relative scoring, was accompanied by farmer’s explanations to reveal the existing local knowledge about land use values. It was found that HTG ≥ SSW > BTP > CF for both social and ecological values. Though this trend applies for the medium and rich households, the poor ones chose SSW as the most valuable. With increasing distance from a forest, the social and ecological values of land uses increased. The accompanying scoring justifications indicated the existence of in-depth ecological knowledge, which conform to contemporary scientific reports. Generally, this study showed that social and ecological values, besides financial values, strongly influence farmer’s decision in implementing various practices related to the land use types. Thus, such values are worth considering for a holistic understanding of the diverse benefits of land uses. Finally, the strong preference for tree and shrub-based land use types is a good opportunity for enhancing tree and shrub growing to minimize the major environmental problems (e.g., soil degradation, wood shortage and deforestation) in the central highlands of Ethiopia.     

Establishing the green neighbourhood: approaches to neighbourhood-scale sustainability certification in Portland,Oregon

ABSTRACT

While local governance is widely acknowledged as an important element in the pursuit of sustainability, local action alone is insufficient to produce lasting change. One recent solution to this quandary has been the production of certification frameworks that encourage sustainable development at the neighbourhood scale by providing local actors with standardised definitions of sustainable practices. While these frameworks facilitate the spread of sustainable development strategies between local communities, there are significant contrasts between their approaches to encouraging local sustainable development that simultaneously fulfils global objectives. This article explores these contrasts through two neighbourhood-scale sustainability certification frameworks: LEED for Neighborhood Development (LEED-ND) and the EcoDistricts Protocol. Analysis of these frameworks in the context of two centrally-located neighbourhoods in Portland, Oregon, reveals substantial contrasts between the two frameworks in terms of the relative flexibility of their sustainability metrics, the time frame over which decisions regarding sustainable development are made, and community involvement in the process of pursuing specific objectives. Furthermore, it suggests that greater flexibility in the application of standards, continuous governance, and greater community involvement lead to more dynamic and holistic forms of sustainability that evolve as both local community needs and broader understandings of sustainability change over time.     

Measuring neighbourhood air pollution: the case of Seattle's international district

Current US regulatory air quality monitoring networks measure ambient levels of pollutants and cannot capture the effects of mobile sources at the micro-scale. Despite the fact that overall air quality has been getting better, more vulnerable populations (children, the elderly, minorities and the poor) continue to suffer from traffic-related air pollution. As development intensifies in urban areas, more people are exposed to road-related air pollution. However, the only consideration given to air quality, if any, is based on ambient measures. This paper uses an inexpensive, portable Particle Soot Absorption Photometer (PSAP) to measure Black Carbon (BC) emissions, a surrogate for diesel fuels emissions, in Seattle's International District. With the aid of a GPS receiver, street-level BC data were geocoded in real space-time. It was found that pollution levels differed substantially across the study area. The results show the need for street-level air pollution monitoring, revisions in current land use and transportation policies, and air quality planning practice.     

Think globally,act locally: neighbourhood pollution and the future of the earth

Each year governments and industry around the globe spend billions of dollars in search of treatments and cures for diseases that shorten lives, which often means gadgets, implants, radiation and pills. These “cures”, do not get to the root of the problem. Perhaps it is time for us to adjust our thinking to be more proactive instead of reactive in public health. Perhaps we need to consider confronting environmental pollution of air, soil and water at a local level. As the Physicians for Social Responsibility point out, we should be “preventing what we cannot cure”. One such preventive measure is ensuring that our communities, including our poor inner-city neighbourhoods, enjoy a clean environment. We challenge local and national policy-makers to respond to the global call and to take action to address environmental toxins; to take local action to ameliorate the pollution of the air, water and soil in so many of our nation’s neighbourhoods. A person’s neighbourhood, and the proximity of dangerous environmental contaminants within it, is a powerful predictor of how long s/he will live. While situations like the poisoning of the water in Flint, Michigan have gotten some attention, they are generally treated as the exception rather than a reflection of real environmental hazards that exist in the west. Moreover we wonder why more endemic issues of neighbourhood environmental contamination that shorten human lives are not a priority for local action or that it is not linked to disproportionate production of greenhouse gases that cause climate change/warming/chaos.     

Urban land use,mobility and theory of science: exploring the potential for critical realism in empirical research

Academic discussion where the adequacy of positions within theory of science is illustrated by means of examples from empirical research studies seems to be an area of neglect. The purpose of this paper is to contribute to such a debate, using examples from investigations into the relationship between urban structure and travel behaviour. The main research question of these investigations was whether, and to what extent, urban structural conditions are influencing residents' transportation activity. In other words, is there a causal relationship between urban structure and travel behaviour? Furthermore, we asked whether results from studies of the relationship between land use and transport can provide a basis for predictions about the likely consequences of alternative land-use strategies. The methodology and empirical findings of the studies are discussed in the light of the theory of science position labelled ‘critical realism’, in an attempt to relate theory of science to empirical research, but also in order to contribute to the discussion of the usefulness of this specific approach.

Modelling built-up land take in Europe to 2020: an assessment of the Resource Efficiency Roadmap measure on land

Land taken by artificial surfaces has an impact on the quality of life and ecosystems. To reduce possible negative impacts of land take, the European Commission proposed setting a milestone objective for 2020 in terms of future rates of land take.

This paper describes a methodology to model the impacts of the 2020 land-take milestone proposed in the RERM in the European Union 27 MS. An integrated modelling framework was configured to assess the spatial impact of two land-take scenarios: a ‘Reference’ scenario, which is driven by demographic and economic trends, and a ‘Target 0’ scenario that follows the 2020 land-take milestone proposed in the RERM. We conclude that the implementation of the 2020 land-take milestone, by reducing future land take in Europe, will foster more efficient use of land (less land taken for the same activity levels) and minimise negative impacts on non-artificial land uses.     

Residential Care in Los Angeles: evaluating the spatial distribution of facilities and neighbourhood access to care among older adults

ABSTRACT

Residential care has increased in number of facilities and has grown in density in urban areas, yet it is disproportionately dispersed in cities and only beginning to meet the current long-term care need of older adults as an alternative to institutional and in-home care. California State Department of Social Services residential care facility data were linked with Los Angeles County census tract data to examine the spatial distribution of facilities through hot spot analysis of clusters of small and large facilities and zero-inflated negative binomial regression of census tract facility counts on older age and race groups, older disabled adults, and older adults in poverty in the area. The results show clusters of large facilities west of downtown Los Angeles and clusters of small facilities in the northern suburbs of the city in the San Fernando Valley. Increases in pre- and early-retired adults and older Hispanics in census tracts are associated with the greatest decreases in facility tract capacity in the area, whereas increases in the oldest old and older disabled adults are associated with the greatest increases. Understanding spatial disparities in residential care can help local agencies and developers plan and partner in more intentional and equitable development of facilities. The greatest opportunity for such development may lie in institutional tools for eldercare facility development such as the eldercare facility ordinance of Los Angeles and development of board and care facilities in residential zones of Los Angeles and other cities.     

The decline of a regional fishing nation: The case of Ghana and West Africa

Inadequate trade policies, globalization of the fishing industry, dominance of Europe's distant water fleets, declarations of exclusive economic zones (EEZs) by neighbouring West African nations, overfishing and a lack of good governance contributed to the decline of Ghana as a regional fishing nation, a position it had held since the 18^th century. The prohibitive cost of access arrangements limited Ghana's access to distant waters. The country's marine environments have been impacted by overexploitation of stocks and the use of destructive methods. Subsistence fishing has become the sole means of survival for many fishers. The decline of the fishing sector has limited the country's ability to meet domestic demand and threatened the economic and food security of many Ghanaians. The article traces the early history of Ghana's fisheries, their gradual decline during the last four decades, and outlines recommendations for policy changes to address the situation and steer the nation on a course towards sustainable fisheries.     

The geoenvironmental cycle of cadmium: a case study

Amidst the hue and cry about anthropogenic sources of pollution, there are regions in the world facing silent metal discharges purely due to geochemical factors. The present investigation relates to such a situation and deals with the non-anthropogenic discharge of cadmium into the local environment. The phosphorite rocks of the Roorkee area of India contain cadmium and, particularly as these are used in the manufacture of superphosphate, the rocks could lead to the large-scale disbursement of cadmium into the open environment. The area under study has soil rich in cadmium-containing minerals, as a result of which water is likely to leach out mobile cadmium and the ground water and crops could become contaminated. This is evident from the high values of cadmium in the tap water and food samples in the area. The Ganga and the Yamuna, the two major rivers traversing the area that originate in the central crystalline rocks of the Himalayas, show high cadmium values at Rishikesh and Dakpathar. Moreover, the sediments of these rivers have cadmium in easily bioavailable form. Food samples and milk analysed from the area show, in some cases, cadmium levels above the safety limits. This high exposure to cadmium is probably causing ailments so far unreported.     

Product life cycle: The key to integrating ehs into corporate decision making and operations

A consensus is emerging that traditional environmental health and safety (EHS) programs—characterized by EHS professionals serving a support function to a company's main operations—represent only part of effective EHS management. In order to be truly successful, EHS management must go beyond this format and integrate EHS considerations into the corporation itself, from its strategic corporate decision making to its everyday operations on the manufacturing floor. Only when EHS becomes part of the fabric of a business's activity will EHS risks and costs be truly minimized—and the many potential benefits fully realized. This article discusses how to make this goal a reality by use of the manufacturing and product life cycle (PLC) perspective. It will first stress the importance of integrating EHS considerations into corporate decision making and operations. It will then trace the critical steps for achieving such integration through the use of the PLC, concentrating particularly on a General Electric Company (GE) chemical management process that weaves EHS concerns into every stage of day-to-day operations.     

Structural challenges that contributed to the decline of the communities for climate protection programme

In 2004 New Zealand's (NZ) Labour-led government launched the Communities for Climate Protection – NZ (CCP-NZ) programme. Following a shift in Government leadership in 2008, from Clark's Labour-led to Key's National-led government, the CCP-NZ programme was discontinued. Through the narratives of managers charged with the implementation and delivery of the CCP-NZ programme, this paper explores the structural challenges that contributed to the initiative's decline in NZ local government. This research contributes to the academic literature by shedding light on the outworking of a local government carbon management strategy. Additionally, this study provides policy makers and managers seeking to embark on organisational carbon mitigation the opportunity to glean insight from the experience of public sector managers responsible for the CCP-NZ programme.     

From landfill to water,land and life: The creation of the Centre for stone materials aimed at secondary processing

This paper focuses on the creation of a Centre for the recycling of stone materials. The Centre will be able to offer a range of activities amongst which is the improvement of the production chain of the Orosei Marble district in Sardinia, Italy. Several companies operate within the marble producing area, specializing in both quarrying and stone processing. They have formed a Consortium in order to rehabilitate an area of more than 17 ha. The restoration will be carried out through an environmentally sustainable procedure. The area was previously used as a landfill for waste deriving from marble quarrying and processing. At that time unshaped blocks of various sizes (which are unsuitable to block-cutter sawing), waste deriving from both block sawing and slab/strip cutting (such as broken slabs, strips, tiles) and microfine dust from filter presses of water treatment plants were representing an environmental problem. The local administration was struggling to find new areas which could be used for landfills, resulting in an additional cost for the landfill, ultimately affecting the variable production costs. The project involves the building of a venue to be used for temporary storage, treatment of wastes produced by both quarrying and primary processing, in order to make them suitable as secondary raw materials. The project also deals with the catch basin hydrology of the area involved in the project, the building of a multifunctional centre, the landscaping and other environmental features such as vehicle traffic and slopes greening.     

TIM: Assessing the sustainability of agricultural land management

TIM (Threat Identification Model) is a framework for the ex ante assessment of agricultural land management sustainability at the land unit scale that identifies sources of unsustainability within agricultural land management systems. The model explicitly links defined hazards to land productivity and environmental integrity, land resource data and information, and land management practice options using expert and local knowledge on land management and its potential effects. The model was tested in the Crystal Creek Subcatchment, a narrow coastal strip of land situated in north Queensland, Australia. This area was chosen due to the expansion of the sugar industry onto increasingly marginal land in the area, which represents a threat to sustainable land use and a requirement for careful land-use planning and land management.TIM may be used in a relational database as a stand alone decision support system for land-management planning. Its usefulness in land-use planning is greatest when it is linked to a Geographic Information System (GIS) as shown in this paper. GIS allows TIM outputs, such as constraints to agriculture and site-specific best-management practices, to be identified in a spatially explicit manner.The main advantages of TIM are that it can be done ex ante, it removes the need to define sustainability assessment criteria and indicators, it utilises current understanding of the causes and effects of land degradation and how different land-management practices influence these, and links this knowledge to definite land-management options.
