Rapid urbanisation, population growth and changes in lifestyles in low- and middle-income countries contribute to increasing the per capita domestic waste generation. This trend leads to deplorable environmental and public health conditions, especially in rapidly expanding cities of low- and middle-income countries lacking appropriate waste management systems, Santiago de Cuba is no exception. To improve solid waste management in the city of Santiago de Cuba, the generation of household waste was studied and individual waste treatment approaches were assessed. The principle of a household level analysis was adopted to enable the development of strategies based on the specific conditions of households, their awareness and needs.In February 2004, a survey covering 1180 households was conducted on issues such as monthly consumed goods, waste generated and its treatment. The waste generated by the households was subsequently assessed by means of a measuring campaign. The measured volume not only comprised the collected waste fraction but also the waste materials treated on-site or recovered and recycled by all the different means available.The paper contains the results of the composition and distribution of the waste generated by the households as a function of socio-demographic data. Furthermore, the paper describes the various household treatment strategies dependent on specific waste material types. Several types of household waste can be differentiated by statistical cluster analysis. These household types are characterised not only by the amount of waste generated but also by socio-economic status and waste treatment practices. The results obtained are used to develop a range of waste management strategies, each relating to a household type and characterised by its generated amount, waste material type and spatial urban distribution. Since the strategies are adapted to the requirements and needs of the households, they are more readily accepted by the population concerned. Such socially anchored strategies will contribute to improving the waste situation in the city of Santiago de Cuba and allow an optimised allocation of local resources.  相似文献

The role of the urban common (i.e. shared space and resources) in sustainable provisioning of goods and services to city dwellers is discussed in this paper. Focusing on tree-based green infrastructure, the study scope includes three categories of provisioning (woody biomass, food/fibre, and non-timber forest products, i.e. NTFPs), alongside three categories of supporting services (fresh water replenishment, soil nutrient restoration, building preservation). As a first step, prospects of utilizing the urban common as facilitator of nature-based solution to the earmarked provisioning services are evaluated through dedicated literature survey and expert elicitation on perceived impact of environmental change triggers and management interventions (planning and/or governance). This is followed by a structured review of the state of affairs in four European cities (London, Amsterdam, Sofia, Ljubljana), representing different macro-geographical regions with distinct socio-economic drivers in managing these provisioning services. The pan-European expert elicitation exercise noted active management of the urban common as positively impacting on the performance of the majority of provisioning services, while environmental change impacts were found to be overriding and adversely influencing the provisioning of material resources (mainly NTFPs and woody biomass). The four-city case study highlighted some regional peculiarities in connecting the city dwellers to the urban common and identified the need to overcome socio-cultural barriers for enhancing pan-European best practice sharing in the management of goods and services provisioning. This is deemed essential to pave way for an emerging perspective on sustainable utilization of the urban common as an enabler for nature-based solution, making it fit for purpose in meeting the astronomical demands of future urban living.

This paper presents two case studies on the efforts by a community-based organisation to promote a sustainable integrated waste management system in Indian mega cities. This effort was initiated in 1989 by a local non-governmental organisation (NGO) called EXNORA and is based on a ‘zero waste management scheme’ set up, run and financed by the residents themselves. As this model has been widely quoted as successful, the study aims at learning from two communities implementing this model.Results are reported from a survey of the two schemes that used various tools to assess both their performance and sustainability in selected residential areas of two Indian cities, Chennai and Hyderabad. The results indicate limited success of the schemes both in saving a significant fraction of the generated waste from dumping, and in rehabilitating the local poor. However, they show that motivated individuals can successfully set up and manage waste collection systems that lead to overall environmental improvements. The differences in the two schemes reflect how the local assets and contexts impact on the success of the scheme. The scheme in a rich neighbourhood of Hyderabad was less ambitious in its overall objectives and focussed on the provision of a waste management service, using the opportunity to provide local employment to a socially deprived fraction of the population. The scheme in a middle-class area of Chennai, although pioneering in its approach, suffered from diseconomies of scale and lack of social integration, making it less viable in the medium to long term. Both schemes suffered from a lack of community involvement, motivation and political support, which threatens the long-term sustainability of the enterprise. The research concludes that the role that communities can realistically play in management of their own waste depends on the local context. The system advocated by EXNORA seems to require significant local resources, and political and technical support which are hard to find and sustain without strong local leaders. Another model set up in the city of Visakhapatnam is finally introduced as an alternative. This is based on triangular contracts between the municipality, the residents and micro-enterprises and may provide a good solution in dealing with the technical and commercial aspects which communities find difficult.  相似文献

In a multilevel and multicentric governance arena, pathways and mechanisms of influence are several and non-state capacities for technical leadership and norm entrepreneurship prove more significant than is the case within a strictly multilateral framework. Among actors with such capacities are municipalities, which multiply their influence through horizontal and vertical relationships. Transnational municipal networks present opportunities for both intermunicipal dialogue and the pooling of global influence, highlighting the presence and influence of the city in the world. This paper examines the collective response of some cities to climate change, exploring the place of cities in global environmental politics through analysis of two transnational municipal networks: the International Council of Local Environmental Initiatives' Cities for Climate Protection and the International Solar Cities Initiative. The article addresses the following questions: How might municipal efforts toward a climate-stable future be significant to the larger issue of ecological justice in global environmental politics? Might cities be able to redefine the rules of the game and take a stand on ‘inefficient’ norms? After briefly accounting for the relationship between cities and the world, the article characterizes technical leadership as a legitimizing force of and in global environmental governance and norm entrepreneurship as a potential source of contestation and subversion in global environmental politics. The paper describes what cities are globalizing, in terms of pollution, environmental degradation, and risk, and in terms of management and politics. Finally, the article explores the possibility that emerging horizontal and vertical relationships, intermunicipal relationships, and relationships between cities or networks of cities and other scales of governance potentiate legitimizing roles for cities in climate governance and subversive roles in climate politics.  相似文献

Cities are dynamic economic and social structures that play a dominant role in both national and international economies. They are centers of population, production, consumption, and development. Cities utilize all advantages of economy of scale, proximity, and concentration. On the other hand, they produce high environmental pressures and diminish thereby the quality of life for urban residents. Indicators (environmental, economic, and governance and management) are seen as a tool that would help policy-makers in formulating urban policy that would lead cities towards sustainability and provide assistance for monitoring their development and municipal performance. The aim of this paper is to consider the role that urban indicators can play in city management. We present basic features of urban indicators that will determine their usefulness in urban management. This paper provides the framework to include environmental and economic indicators, as well as governance and management indicators, in successful urban management.  相似文献

Liberia has gone through civil crisis for over a decade which has resulted in the destruction of infrastructure and disruption of basic services delivery particularly in Monrovia, the capital city. Most of the 1.3 million people living in Monrovia are without adequate environmental sanitation and waste management services which situation poses a serious health risk to the residents. The current waste management service coverage is less than 20% and disposal is by indiscriminate open dumping. In 2003, there were series of outbreaks of cholera epidemics in the city during which time a total of 26,651 cases were reported with many dying.The waste management plan was initiated as an exit strategy of UNICEF following an intervention response programme to assist the Monrovia City Corporation (MCC) whose capacity in this area had been crippled as a result of years of war, through the provision of support in solid waste collection and disposal.The objectives of the plan were to:
(a) Improve waste management services delivery in the city.
(b) Strengthen the ability of the MCC to plan and manage the waste services delivery.
(c) Enhance cooperation of service beneficiaries through comprehensive and effective health education and service promotional campaign.
(d) Enhance revenue generation and community participation through the promotion of private sector and CBOs/NGOs active involvement in the waste management service delivery.
The general methodology adopted for the assignment entailed the following:Desk study and review of existing reports on Water and Environmental Sanitation (WES) in Monrovia and other relevant literature, consultation with stakeholders, site visits and participatory planning which aimed at soliciting the opinions of the various stakeholders involved with the respective components to capture their aspirations and experiences. It also covered collection and analysis of available information and data to facilitate the plan preparation and facilities design.The three-phased strategy (short, medium and long term) covering a period of 10 years (August 2004–December 2014), recommended a combination of technical options for collection based on the pursuit of staged development to allow for the adoption of realistically attainable standards within a framework of continuous and systematic improvements as economic conditions improved and new knowledge gained through practice. The plan sought to blend the capacity within the City Corporation with that of the private sector and NGOs/CBOs to respond to the diverse service demands of the city taking into consideration housing and infrastructural conditions, service costs and cost recovery to ensure sustainability. It also identified sources of financing and allocated financing responsibilities to facilitate effective plan implementation.  相似文献

Many thousands of people in developing country cities depend on recycling materials from waste for their livelihoods. With the focus of the Millennium Development Goals on poverty reduction, and of waste strategies on improving recycling rates, one of the major challenges in solid waste management in developing countries is how best to work with this informal sector to improve their livelihoods, working conditions and efficiency in recycling.The general characteristics of informal recycling are reviewed, highlighting both positive and negative aspects. Despite the health and social problems associated with informal recycling, it provides significant economic benefits that need to be retained. Experience shows that it can be highly counterproductive to establish new formal waste recycling systems without taking into account informal systems that already exist. The preferred option is to integrate the informal sector into waste management planning, building on their practices and experience, while working to improve efficiency and the living and working conditions of those involved. Issues associated with integrating informal recycling into the formal waste management sector are discussed.  相似文献

In recent decades unprecedented urbanization has constituted a huge challenge to urban infrastructure development and management in most developing countries. Meanwhile, the appropriateness of conventional urban planning approaches to the improvement of urban environmental conditions in the face of deteriorating urban environment have often been questioned. It became inevitable to search for new approaches particularly in the context of low-income urban communities. International organizations such as the United Nations Development Programme (UNDP) and the United Nations Centre for Human Settlements (UNCHS) have subsequently initiated strategies to evolve a participatory approach to the development and management of the urban environment. One of such strategies is the Sustainable City Programme (SCP) which aims to provide municipal authorities and city stakeholders in the public, private and community sectors with an enhanced capacity for environmental planning and management. The programme is being implemented in several cities in parts of the developing world, including Ibadan – the Sustainable Ibadan Project (SIP) – in Nigeria. This paper examines the partnership approach to urban environmental infrastructure improvement, development and management as represented by the SIP. The relevance of the participatory partnership approach of the SIP for cities in parts of developing regions is examined. The paper implicitly stresses that bottom-up participatory stakeholder partnership is a strategy capable of enlisting the financial, material resources and expertise of various sectors of the urban community towards the improvement of urban environmental infrastructure. The paper presents preliminary findings of a study. Although traditional appraisal techniques were not employed, nonetheless, the paper presents a discussion of the processes and dynamics of the SIP on the basis of which some useful lessons may be drawn.  相似文献

Editorial     
The urbanization of populations worldwide continues. Concurrently, poverty is increasingly being urbanized. In 1950, there were only 10 cities with populations of 5 million or more; in 1993, there were 33, six of which had 15 million or more inhabitants. This editorial introduces a group of articles which examine gender issues and human settlement, emphasizing the interconnectedness of all aspects of men's and women's lives, and the links between people's physical surroundings and what they do to survive. For the majority of men and women living in cities in the developing world, the reality of urban life is survival through informal work and a shelter in an unplanned area, which is likely to have few essential services such as health centers and schools, and may have no clean water supply, sanitation, trash collection, or power. There is increasingly inadequate public provision of housing and basic services, and a growing number of de facto female-headed households, especially in the poorest social sectors. In some Northern cities in recent years, growing numbers of homeless people live on the streets or in substandard accommodation in conditions of extreme deprivation. Diversification as a coping strategy; the reality of women's work; planning; making rural/urban links; understanding migration; land and shelter; cities, freedom, and fear; environmental concerns; and finding solutions are discussed.  相似文献

Although e-government initiatives have been credited as enginesof government reform, empirical evidence is insufficient todetermine their effects on public sector performance. To explorethe impact of e-government on local governance, this articleexamines how e-government initiatives influence the perceivedperformance of environmental decision making in an urban contextand what organizational and contextual factors affect Web-aideddecision performance. Data were collected from the content analysisof city government Web sites and a nationwide survey of cityofficials in Korea. Findings from path analysis show that (1)information technology leadership of senior management and Website quality are key to decision intelligence, quality, andspeed and (2) e-government Web divide, a gap in the capabilityof city Web sites to support public service delivery and democraticinteraction, translates into disparities in environmental decisionperformance across cities. Additionally, environmental activismis a significant factor shaping the impact of e-government onenvironmental decision making. E-government initiatives contributeto local governance performance, but their impacts vary, dependingon Web site quality and the entrepreneurial leadership of publicmanagers.  相似文献

Novel approaches to natural resource management, particularly those which promote stakeholder participation, have been put forward as fundamental ingredients for establishing resilient, polycentric forms of environmental governance. This is nowhere more pertinent than in the case of the complex adaptive systems associated with urban areas. Decentralisation of urban green space management has been posited as an element thereof which, according to resilience thinking, should contribute to the adaptive capacity of cities and the ecosystem services upon which they rely. Implicit in this move towards increased adaptive capacity is the ability to manage through innovation. Although the importance of innovation towards system adaptability has been acknowledged, little work has thus far been carried out which demonstrates that innovative use of urban green space represents a form of adaptive response to environmental conditions. The current paper reports on research which maps examples of organised social-ecological innovation (OSEI) in an urban study area and evaluates them as adaptive responses to local environmental conditions which may contribute to system resilience. The results present OSEI as a coherent body of responses to local social and environmental deprivation, exhibiting diversity and adaptability according to individual contexts. The study therefore provides evidence for the importance of local stakeholder-led innovation as in the building of adaptive capacity in urban social-ecological systems.  相似文献

This study compared the socioeconomic status, racial composition, and ethnic composition of 49 randomly selected U.S. cities with those of the census tracts containing the solid waste disposal facilities and sewage treatment plants for those cities. Contrary to the environmental racism and classism hypotheses, residents of tracts with landfills or incinerators had higher incomes and were less likely to be minority group members than residents of the cities that generated the refuse—although they did have somewhat lower education levels. There were few differences between the population characteristics of the cities and the census tracts that contained their sewage treatment plants. Possible explanations for these findings are discussed.  相似文献

The goal of this study was to assess the existing solid waste management stream in Kabul, Afghanistan, as a basis for developing a sustainable solid waste management system. Achieving the goal of this study necessitated (1) assessment of the major factors affecting the solid waste stream and it collection; (2) estimation of the solid waste generation rate; and (3) characterization of the solid waste composition. The solid waste characterization data demonstrated that the solid waste stream in the city of Kabul, although similar to low income countries in Asia, especially to South Asian countries, is unique in composition and solid waste generation rate. The solid waste stream was characterized with large organic fraction of approximately 70% and specific weight of 413 ± 52 kg/m3. The estimated solid waste generation rate ranged between 0.31 and 0.43 kg/capita/day. It is expected, however, that the solid waste stream characteristics for the city of Kabul will change over time to be similar to waste streams of cities in the region with similar socio-economic, cultural and religious background.  相似文献

The issue of poor solid waste management (SWM) is a challenge throughout the world, in both developed and developing countries. People always generate solid waste through their daily activities. This solid waste needs to be properly managed in a way that minimises risk to the environment and human health, which means storage, collection and proper disposal. At the same time solid waste creates livelihoods for the urban poor in terms of employment and business. This paper looks into one aspect of SWM, namely collection service.The importance of SWM is now recognised at international, national and community level. The Agenda 21 declaration of the United Nations [UN. (1993). The global partnership for environment and development: A guide to agenda 21 (pp. 88–94). New York: United Nations] addresses the issue of environmentally sound management of solid waste, with emphasis on the extension of solid waste service coverage to all urban and rural areas worldwide.SWM is a service for which local governments are usually responsible. However, due to inadequate capacity in the public sector, in many developing countries the private sector has stepped in to fill the gap in service provision. Dar es Salaam (DSM), Tanzania, is one such developing country city in which the private sector has become involved in solid waste collection services. The sector comprises Non-Government Organisations (NGOs), Community-Based Organisations (CBOs), and local private companies [Kassim, S. M., & Ali, S. M. (2003). Private solid waste collection SERVICE, Dar es Salaam Tanzania. In Proceedings of the 29th WEDC international conference: Towards millenium development goals. Abuja Nigeria, Water and Engineering Centre WEDC]. The private sector in solid waste collection in DSM has been promoted by Sustainable DSM Programme (SDP) through Environmental Planning and Management (EPM) [UNCHS. (1994a). Sustainable Human Settlements Development: Implementing Agenda 21; UNCHS. (1994b). UNCHS (Habitat) Activities; New Envoy to UNCHS from the United Republic of Tanzania. Habitat News, 16, 1–3].Contracting out of solid waste collection services to the private sector has emerged to fill the gap in service delivery. In 1991 the city was generating 1400 tonnes of solid waste per day out of which only 5% was being collected. Currently daily solid waste generation is estimated at about 2500 tonnes and approximately 48% of the total waste generated is collected. At present, privatisation covers 44 out of 73 city wards, and 451 active registered private companies are involved [Chinamo, E. B. M. (2003). An overview of solid waste management and how solid waste collection benefits the poor in the city of Dar es Salaam. Solid waste collection that benefits the poor, Dar es Salaam, Tanzania, Collaborating Working Group on Solid Waste Management in Low and Middle -Income Countries (CWG)].This paper presents the findings of a study that explored the households’ perspective on solid waste collection services provided by the private sector. The study showed that the solid waste collection service by the private sector is greatly influenced by households’ attitudes and behaviour. Their participation, demand for service, awareness, satisfaction level and views on cost recovery are important in the sector. The study concludes that the above factors would be superior if customers (households) were more involved in the planning and decision-making.  相似文献

It is argued that Nigeria must focus on effective environmentally protective intensive farming, resource management methods, and strong family planning programs. Other contributory factors are recognized as the lack of democracy and the "ill-advised" internal policies of the government. The emphasis is on man-made decisions about migration, natality, and land use practices that have ecological consequences that significantly affect the economy. Land degradation in Nigeria is attributed to improper agricultural and husbandry practices. Land degradation has severe ecological, economic, and human costs. Awareness of environmental problems in Nigeria is growing. Natural disasters such as the droughts of 1984-85, continued soil depletion, accumulations of soil wastes, increased flooding in urban areas, and land erosion in Anambra state are evidence of the growing environmental problems. Agricultural development should involve changing rural land use practices, using technology that is "appropriate" to the climate, crops, and culture of the people, and introducing agroforestry. Population growth in Nigeria puts pressure on the fragile ecosystem. Actual carrying capacity is a rough calculation. Nigeria's population growth patterns follow a pattern that suggests population pressure on carrying capacity. The acceleration of population growth has strained the traditional system of agriculture. Land is overused, and cultivation continues on unsuitable land. Domestic policies during the oil boom encouraged rapid industrialization at the expense of the environment. Migration increased to urban centers, but cities did not provide suitable housing, waste disposal, safe water supplies, and other basic facilities.  相似文献

Abstract Decisions regarding hazardous waste facility siting are now open to extensive public debate. Efforts on the part of public officials and private companies to site waste management facilities have been thwarted by public opposition. Using survey data from leaders and residents in communities which are hosting or siting facilities, this study examines their sociodemographic characteristics, knowledge, levels of trust, perceptions of risk, perceptions of economic impacts, perceptions of equity issues and the differential effects of these factors on acceptance of local waste facility siting. Leaders in these communities were more supportive of local waste facility siting than were other community residents. The major determinant of leaders' acceptance of waste siting was their perceptions of the economic benefits of a facility to the community. Although this was also important to residents, perceptions of health, safety, and environmental contamination risks had larger effects on their acceptance of such facilities.  相似文献

The development of initiatives for Local Agenda 21 for the cities of Peru, their documentation for the “best practices” programme of HABITAT II, and the demand for a formalized programme of support, capacity building and technical assistance has stimulated the establishment of the Peru Urban Management Education Programme (PEGUP). The PEGUP represents an innovative approach to capacity building, working through different mechanisms of education and training, technical assistance to municipal development of Local Agenda 21 and the promotion of networking and experience exchange. The experiences to date indicate that the set of support mechanisms is in line with the requirements of local governments which need a variety of support on the long road to develop urban management capacities that allow the solution of their urban and environmental problems. PEGUP offers a variety of services which are part of the development strategy of “Forum of Cities for Life” network.  相似文献

Guardianships and conservatorships are currently used to carry out public policy concerning protection of and advocacy for elderly people who cannot care for themselves. This article analyzes this public policy with the idea in mind that the legal aspects of guardianships and conservatorships must be linked with clinical assessment in order for public agencies to provide high quality, need-based services for individual clients. The article also explores the notion that case management for such clients involves coordination of services between the court system and human services providers.  相似文献
