A model of costs and resources for rural and peri-urban water supply and sanitation in the 1990s

This article develops a model of cost and financing strategies for rural and peri-urban water supply and sanitation. It suggests that significant progress towards the World Summit for Children's goal of universal access to water supply and sanitation can be made if a combination of strategies is adopted. On the cost side, significant cost reductions should be possible through efficiency in resource use and reduction of system management costs. On the financing side, it suggests restructuring the financing of the sector with improved efficiency and greater cost recovery in urban services; full recovery of operation and maintenance costs; cost sharing through community contributions in kind such as local labour and financially in rural and peri-urban water supply for basic levels of service depending on willingness and ability to pay and full cost recovery for higher levels of service; a high degree of cost recovery in rural and peri-urban sanitation; development of institutional structures for both collection and management of revenues; development of alternate financing mechanisms such as rural credit schemes and revolving funds, adapted in specific country contexts, including the required institutional mechanisms; and additional allocations from governments and external support agencies. Additional government or external financing alone, while critical, will not of itself lead to effectiveness in the use of resources. Equally, cost recovery alone cannot lead to universal access and sustainable solutions. A composite set of actions is needed within which building capacities of institutions and people is necessary for sustainability .     

Local Authority Archaeological Services in Scotland Two Years after Local Government Reorganization

We report a survey of the state of local authority archaeological services in Scotland following local government reorganization. Several service provision models are in place, including a new model of joint provision by councils of the former Strathclyde Region. Several councils which lacked a service before reorganization now buy it in from neighbouring councils. Some gaps in cover however persist. There are good reasons for the variety of models, and it would not be appropriate to seek to impose a single model. Planning guidance issued in 1994 has shifted the balance of service provision towards development control and away from other functions, as resources are squeezed. The implications of the Scottish Parliament are considered.     

A value proposition: Resource recovery from faecal sludge—Can it be the driver for improved sanitation?

There is currently a lack of access to affordable sanitation in urban areas of Sub-Saharan Africa. This study evaluated the potential for resource recovery from innovative faecal sludge treatment processes to generate a profit that could help sustain the sanitation service chain. A total of 242 interviews were conducted in Accra, Ghana; Dakar, Senegal; and Kampala, Uganda to compare markets in different cultural and regional contexts. Products identified to have potential market value include dry sludge as a fuel for combustion, biogas from anaerobic digestion, protein derived from sludge processing as animal feed, sludge as a component in building materials, and sludge as a soil conditioner. The market demand and potential revenue varied from city to city based on factors such as sludge characteristics, existing markets, local and regional industrial sectors, subsidies, and locally available materials. Use as a soil conditioner, which has been the most common end use of treated sludge, was not as profitable as other end uses. These findings should help policy and decision makers of sanitation service provision to design financially viable management systems based on resource recovery options.     

The importance of place in early disaster recovery: a case study of the 2013 Colorado floods

Recovery is an important but understudied phase in the disaster management cycle. Researchers have identified numerous socio-demographic factors that help explain differences in recovery among households, but are less clear on the importance of place, which we define as a household's locality and local governance. In this paper, we examine the influence of place on disaster recovery through a study of the 2013 Colorado floods. Our findings are based on data collected from interviews, observation of recovery meetings, and a survey of 96 flood-affected households. We show that place shapes a household's disaster recovery by structuring: (1) physical exposure to hazards; (2) which local government has jurisdiction over recovery decisions; (3) local planning culture and its approach to citizen participation; and (4) the strength of social capital networks. Our findings expand the recovery literature and show that place-level variables should be taken into consideration when conceptualizing household recovery and resilience.     

Assessing options for the development of surface water flood warning in England and Wales

This paper explores the technical options for warning of surface water flooding in England and Wales and presents the results of an Environment Agency funded project. Following the extensive surface water flooding experienced in summer 2007 a rainfall threshold-based Extreme Rainfall Alert (ERA) was piloted by the Met Office and Environment Agency providing initial steps towards the establishment of a warning for some types of surface water flooding. The findings of this paper are based primarily on feedback on technical options from a range of professionals involved in flood forecasting and warning and flood risk management, about the current alerts and about the potential options for developing a more targeted surface water flood warning service. Providing surface water flooding warnings presents a set of technical, forecasting and warning challenges related to the rapid onset of flooding, the localised nature of the flooding, and the linking of rainfall and flood forecasts to flood likelihood and impact on the ground. Some examples of rainfall alerting and surface water flood warning services from other countries are evaluated, as well as a small number of recently implemented local services in England and Wales. Various potential options for implementation of a service are then explored and assessed. The paper concludes that development of a surface water flood warning service for England and Wales is feasible and is likely to be useful to emergency responders and operational agencies, although developing such a service for the pluvial components of this type of flooding is likely to be feasible sooner than for other components of surface water flooding such as that caused by sewers. A targeted surface water flood warning service could be developed for professional emergency responders in the first instance rather than for the public for whom such a service without further operational testing and piloting would be premature.     

Public–Private Partnerships for Solid Waste Management Services

The increasing cost of municipal solid waste (MSW) management has led local governments in numerous countries to examine if this service is best provided by the public sector or can better be provided by the private sector. Public–private partnerships have emerged as a promising alternative to improve MSW management performance with privately owned enterprises often outperforming publicly owned ones. In Lebanon, several municipalities are transforming waste management services from a public service publicly provided into a public service privately contracted. In this context, a regulated private market for MSW management services is essential. The present study examines a recent experience of the private sector participation in MSW management in the Greater Beirut Area. The results of a field survey concerning public perception of solid waste management are presented. Analysis of alternatives for private sector involvement in waste management is considered and management approaches are outlined.

Mining amid decentralization. Local governments and mining in the Philippines

In recent years, as part of its neoliberal development paradigm, the Government of the Philippines has engaged in efforts to encourage extraction of the nation's mineral resources. The Philippines is also a country where decentralization has devolved substantial powers to local governments. Concern over potentially adverse environmental effects has led to opposition to mining by some local governments in the Philippines. This opposition has led to the withholding of consent to mining projects by local governments and, in some cases, the implementation of moratoriums banning mining. Central to this opposition have been the activities of civil society groups, and their collaboration with local governments. This collaboration has involved the drafting of legislation prohibiting mining and support of candidates for office who are opposed to mining. Collectively, Filipino local governments and civil society groups are examples of the concept of governance, a dispersed process wherein society manages itself for the betterment of all its members. For mining companies seeking to implement projects, it is no longer sufficient to have the consent of the national Government — that of local governance forces must also be considered.     

Minimizing Impacts of Maintenance Dredged Material Disposal in the Coastal Environment: A Habitat Approach

At present, coastal disposal of maintenance dredged material constitutes one of the most important problems in coastal zone management and in some coastal areas represents the major anthropogenic disturbance to the benthos. In this review we first propose, based on the classic literature, that macrofaunal communities typical of environmentally stressed habitats are more resilient than those of more environmentally stable habitats, and we outline the macrofaunal successional changes following a disturbance. Second, from a review and analysis of the published and unpublished literature on macrofaunal recovery following maintenance dredged material deposition in the coastal environment, we compare the successional sequences and recovery rates in euhaline and polyhaline systems. The review reveals that invertebrate recovery following dredged material disposal in relatively unstressed marine environments generally takes between 1 and 4 years, while in more naturally stressed areas, recovery is generally achieved within 9 months, although deeper polyhaline habitats can take up to 2 years to recover. Differences in recovery times are attributed to the number of successional stages required to regain the original community composition and that species typical of naturally unstressed assemblages do not possess life-history traits to allow rapid recolonization of disturbances. In the last section of this review, the management implications of these findings are discussed in terms of minimizing dredged material disposal impacts on fisheries resources. Since the natural disturbance regime appears to be very important in determining the response of a benthic community following dredged material disposal, it is recommended that when predicting the potential environmental impact of an operation, the nature of the physical environment in combination with the status (and role) of associated marine benthic communities should be considered.     

A future for the forest of dean

Summary This article outlines the historical background of the Forest of Dean in Gloucestershire and the Acts of Parliament which have affected its landscape character. Problems relating to the present situation are discussed. These include rights of access, common rights, sales of public land, intrusion of industry, open cast mining and tourism. The suggestion is put forward that there should be a new Act of Parliament establishing a Dean Forest Authority which would be an autonomous estate management body with an executive committee drawn from the many interests in the district. The Forestry Commission, which is at present responsible for management, with its main concern that of commercial tree growing, is not considered to be sufficiently sympathetic to local needs. The author originally intended reading for a Forestry degree at Oxford, but eventually took a degree in Botany at that University (1957). For some time he was Biology teacher at King Edward VI's School, Norwich, and Head of Science at the Blyth School, Norwich. Since establishing the Centre for Environmental Studies for the Gloucestershire Education Authority in the Forest of Dean in 1969 he has become closely involved with a number of conservation organisations in Gloucestershire. He was for a time chairman of the Dean branch of the Council for the Protection of Rural England and the North Dean Reserves Committee of the Gloucestershire Trust for Nature Conservation. Besides writing the occasional paper on field studies and local history he writes a ‘Conservation Piece’ monthly for the local papers. He has been an outspoken critic on a number of local issues on radio, television and in local inquiries.     

A framework for assessing the accountability of local governance arrangements for adaptation to climate change

Accountability has hardly been studied in the governance of climate change adaptation. This paper develops a framework for assessing the accountability of interactive governance arrangements for local adaptation. This framework is based on five important accountability mechanisms: Clear responsibilities and mandates, Transparency, Political oversight, Citizen control and Checks and sanctions. For illustration purposes, the proposed framework is applied to the case of a Dutch local adaptation governance arrangement. The application shows that the five proposed mechanisms and their operationalizations offer a valid assessment of the accountability of such arrangements. It also raises some challenges, such as the tensions between accountability and flexibility, legitimacy and effectiveness; the potentially important roles of trust and of the political skills of central actor(s) in the arrangement in raising accountability, and the potential need to distinguish between arrangements for policy planning and for service delivery.     

Industrial waste to energy by circulating fluidized bed combustion

Industrial waste is a good resource from the viewpoint of efficient waste management. The vital need for energy utilization and environmental protection mean it is of interest to develop circulating fluidized bed combustion (CFBC) to burn solid wastes with low pollutant emissions. The paper presents some explanatory studies on waste-to-energy in a pilot scale CFCB facility. A series of combustion/incineration tests have been carried out for the industrial wastes: petroleum coke, waste tire and sludge cakes with various moisture contents. It seems that the CFBC has feed flexibility without modifying heat transfer equipments for energy recovery. In addition, the results of experimental tests demonstrate that gas emissions from waste incineration in CFBC can be well controlled under local regulation limits.At normal operation temperature in CFBC (approx. 800°C), the heat transfer coefficient between bulk bed and bed wall is on the order of 10² W/m^2° C, which is useful to estimate the energy recovery of waste combustion by CFBC. A practical and simple guide is proposed to estimate the energy recovery from waste combustion by CFBC, and to find maximum allowable moisture content of waste if there is to be any energy recovery without auxiliary fuel.

Intergovernmental relationships after disaster: state and local government learning during flood recovery in Colorado

ABSTRACT

When communities experience disaster, emergency response and recovery are led internally, based on local-level policy decisions and priorities. Decisions about how or whether to rebuild are made by local governments. Higher governmental authorities such as states and provinces may institute their own disaster recovery processes and policies in addition to or in competition with local governments. Greater intergovernmental engagement could increase resources and knowledge, which would yield higher levels of learning and result in superior disaster recovery policy outcomes. The role of higher authorities, then, can have important implications for policy processes and outcomes. The learning literature includes a dearth of studies that analyze the relationships between state and local governments during disaster recovery. We move the learning literature forward by analyzing intergovernmental relationships during disaster recovery. We find that learning within local governments is associated with higher levels of resource flows from state agencies as well as more collaborative intergovernmental relationships. We also find that state governments can improve processes for disaster recovery assistance and bring together disaster-affected local governments to promote learning during the recovery process. While this study focused on relationships constrained by U.S. federal dynamics, the lessons are useful to other multilevel governance systems.     

Policy And Practice The Focus of Local Agenda 21 in the United Kingdom

The paper examines whether environmental issues are taking precedence over socio-economic issues in the UK LA 21 process. A categorization to separate issues which can be considered socio-economic from those which are environmental has been developed and a questionnaire sent to all UK local planning authorities. Results demonstrate that local authorities are indeed giving more emphasis to environmental issues, which is at odds with previous studies and with the concept of sustainability.The research has indicated that the cause may be a tendency to place LA 21 within the remit of environment departments and, whether this is the explanation or not, it implies that a re-emphasis of effort may be required on behalf of the local authorities.     

Estimating the reduction of urban PM10 concentrations by trees within an environmental information system for planners

Trees have been widely quoted as effective scavengers of both gaseous and particulate pollutants from the atmosphere. Recent work on the deposition of urban aerosols onto woodland allows the effect of tree planting strategies on airborne aerosol concentrations to be quantified and considered within the planning process. By identifying the potential planting locations in the local authority area, and applying them within a dispersion and deposition model, the potential magnitude of reduction in the ambient concentration of PM(10), achievable through urban tree planting, has been quantified for two UK cities. As part of the Environmental Information Systems for Planners (EISP), flow diagrams, based on planning decisions, have incorporated output from the model to make decisions on land use planning ranging from development plans and strategic planning, to development control. In this way, for any new developments that contribute to the local PM(10) level, the mitigation by planting trees can be assessed, and in some cases, reductions can be sufficient to meet air quality objectives for PM(10).     

The Park Made of Oil: Towards a Historical Political Ecology of the Kenneth Hahn State Recreation Area

Within the park-deprived inner-city landscapes of Los Angeles, an unprecedented change is underway. Long considered to be the epitome of anti-nature, Los Angeles is witnessing a boom in park development and ecological restoration. Derelict, blighted and contaminated inner-city brownfield sites are being converted to greenspaces, nature parks and wildlife refuges. Indeed, Los Angeles has been the recent recipient of hitherto unimaginable political and fiscal support to ameliorate the dearth of parks in its neglected urban core. This paper situates the current round of park development within its historical context, by focusing on a very particular local site—the Kenneth Hahn State Recreation Area. Applying the theoretical lens of political ecology, the authors trace some of the political, economic, ecological and institutional factors from the late 1920s onwards, which engendered the creation of a park atop an oilfield. In so doing, the authors deepen the understanding of how local greenspace allocation, poverty, race and political power are oftentimes complexly entangled. Precursor to a much larger project currently in the planning and development stages, the creation of the Kenneth Hahn State Recreation Area reveals some of the ways that the Southern California oil industry has shaped nature spaces in Los Angeles.     

Linking management and livelihood in environmental conservation: case of the Korup National Park Cameroon

Biodiversity conservation has emerged within the past two decades as one of the most important global challenges confronting national planners, world bodies, professionals and academics. Governments faced with increasing biodiversity loss as a result of human activities have resorted to the creation of protected areas as a strategy to both slow down habitat loss and/or degradation and eventually mitigate species extension and reduction rates. However, the creation of a protected area can have strong implications on the livelihoods of people inhabiting the forest and depending on it, especially those caught within its borders. The involvement of such inhabitants in the management process of the protected area can be profitable. This paper discusses the case of the Korup National Park, Cameroon, considered in the late 1980s by some to be a flagship of conservation and development efforts, and later on in the late 1990s by others as a catastrophic failure as an example of integrated conservation and development. As a means of updating the program's management information base, an in-depth participatory and socio-ecological survey was conducted by some of the program's technical staff. This study aimed at appraising the extent to which the Park's human community of 4200 inhabitants continued to relate to its resources and depend on them for their livelihood. The aim was to evaluate the potential links between the communities' livelihood and the long-term management and survival of the Park as the important biodiversity conservation zone it had been found to be. Results indicate that the successful management of a Park like Korup may well depend on the involvement of the local communities; and that successful management through approaches that minimize the potential contributions and aspirations of the local people is difficult to achieve.     

Listening to locals on payments for environmental services

Payments for Environmental Services (PES) is gaining recognition worldwide as a serious option for conservation of ecosystems, as well as potentially improving the livelihoods of people providing environmental services. However, little attention has been paid to research on views of local people in their potential roles as service providers. In this research we explore perspectives of poor people living in a National Park in Vietnam, where introduction of PES is being considered. In-depth interviews and workshops were conducted – with strong emphasis on the use of visual techniques, to help facilitate learning processes and provide insight into local perspectives. From the research, two models were developed to indicate general factors that influence the likelihood of people adopting, and adhering to, PES schemes. We suggest these models can be used to guide the design of PES. Our findings also reveal three main requirements important in design of pro-poor PES: (1) Thorough scoping studies for ensuring that schemes are based on sound understanding of potential providers' perspectives and context. (2) Such studies should emphasise qualitative research and draw on participatory tools, to facilitate open dialogue and co-learning by researchers and participants. (3) Policy makers should consider designing hybridized schemes, i.e., in which PES concepts are combined with integrated conservation and development.     

Exploring the origins of ‘social license to operate’ in the mining sector: Perspectives from governance and sustainability theories

In the mining sector, local communities have emerged as particularly important governance actors. Conventional approaches to mineral development no longer suffice for these communities, which have demanded a greater share of benefits and increased involvement in decision making. These trends have been spurred by the growth of the sustainable development paradigm and governance shifts that have increasingly transferred governing authority towards non-state actors. Accordingly, there is now widespread recognition that mineral developers need to gain a ‘social license to operate’ (SLO) from local communities in order to avoid potentially costly conflict and exposure to social risks. A social license can be considered to exist when a mining project is seen as having the ongoing approval and broad acceptance of society to conduct its activities. Due to the concept's relatively recent emergence, however, only a limited body of scholarship has developed around SLO. Drawing on examples from northern Canada, this paper uses governance and sustainability theories to conceptualize the origins of SLO in the mining sector and describe some of the associated implications. Further research is needed to determine governance arrangements which help facilitate establishment of SLO in different mineral development contexts.
