This article summarizes the results of the project on indicators for sustainable energy development (ISED) in Brazil. The project's aim was to present energy related economic, social and environmental data to policy makers in a coherent and consistent form, showing interlinkages, time‐series and cross‐sectoral analyses and assess energy policy. Two priority areas assessed by these indicators, regarding the country's energy supply and demand, helped in the identification of a number of energy policy options that focused on specific aspects of the country's energy sector. On the supply side, these options include the development and stimulation of renewable energy, such as small‐scale hydroelectric, wind, solar photovoltaic power and bagasse cogeneration; stimulation of programmes for ethanol use as automotive fuel and sugarcane bagasse cogeneration; and implementation of natural gas‐fired, combined heat and power (CHP) plants. On the demand side, policy options include: the full implementation of the law on efficiency standards for appliances; expansion of utility investment in end‐use energy efficiency; adoption of targets and protocols to reduce energy intensity in the industrial sector; improvement of passenger transport efficiency; and the creation of a fund to improve energy affordability for the poor. 相似文献

ABSTRACT: Economic models sometimes indicate that irrigation water is misallocated in agriculture, especially when it appears that the marginal value product is higher in other uses (such as for hydro-power). Historically, trends tend to contradict this reasoning, however, especially since irrigation has grown from 20 million acres in 1940 to over 50 million acres in 1980. Results of this study tend to indicate that as agriculture becomes more and more intensive (in terms of inputs), irrigation is part of that long term trend. Further, major economic variables, such as output and investments in agriculture, appear to be more highly correlated with irrigated land than with dryland agriculture. Recent data indicate an upper limit of about 320 million acres for dryland farming in the United States, while no such constraint is apparent for irrigated agriculture. 相似文献

In the aftermath of the 1979 revolution, the new administration adopted a number of policies to address the question of land ownership, supply and allocation in order to tackle the acute shortage of housing in the urban areas. In 1982, the Five‐Year Urban Land Act was passed by the Parliament. Subsequently a body called the Urban Land Organisation (ULO) was set up to co‐ordinate the process of land preparation and allocation. The 1982 Urban Land act empowered the government to: (a) expropriate certain categories of abandoned urban land, and (b) to set a temporary time schedule of five years during which the act's work will be monitored.
This paper sets out to examine the policies related to urban land which have been introduced and implemented in the 1980s in Iran. 相似文献

Poverty is rampant in the rural areas of Pakistan, where people are in a state of deprivation with regard to incomes, clothing, housing, healthcare, education, sanitary facilities and human rights. Agriculture generates nearly 20.9 percent of the country's GDP and provides employment for 43.4 percent of its workforce. Most importantly, 65.9 percent of the population living in rural areas is directly or indirectly dependent on agriculture for their livelihood. Rising population, shrinking agricultural land, increasing demand for water resources, widespread land degradation and inadequate infrastructure appear to be major concerns of the agriculture sector in Pakistan. An attempt has been made to examine the population growth–agriculture growth–poverty alleviation linkage. It is argued that agriculture will continue to be one of the most important sectors of Pakistan's economy for years to come. To alleviate poverty, it is suggested that Pakistan enhance the productivity of the agriculture sector through the provision of a series of inputs including provision of easy credit to the small farmer, availability of quality fertilizers and pesticides, tractor and harvester services, improvement in the effectiveness of the vast irrigation system and, finally, farmer education. It is concluded that the high rate of population growth needs to be curbed for increased agricultural productivity to have any significant effect on poverty in rural areas of Pakistan. 相似文献

In the transport sector, few projects applied Clean Development Mechanism (CDM) or Joint Implementation (JI) projects. This
study will examine the feasibility of applying CDM to the transport sector from viewpoints of validation of processes and
funding. A number of greenhouse gas emission reduction projects, as well as traffic management project within existing transport
infrastructures, can be implemented as CDM projects. New transport infrastructure projects can be validated by transportdemand
forecasting and traffic simulation methods, though application of Life Cycle Assessment (LCA) and Intelligent Transport Systems
(ITS) technologies.

Corporate strategy and viable future land use: planning for closure from the outset of mining 总被引:2,自引:0,他引:2
This paper provides an overview of the environmental impact of mining on viable future land use and underlines the imperative of improved environmental management and closure planning. It argues that pollution prevention, through planning for closure, can lead to cost-effective strategies for sustainable minerals development and viable future land use. This seems to be most true for greenfield sites since, generally, the earlier closure planning and pollution prevention is built into a project, the more cost-effective and environmentally benign closure will be. Further, for greenfield sites, pollution prevention techniques can be employed from the outset, at the stages of exploration and mine development, and then monitored and improved through the operation stage to closure, and can be kept in place to manage future land use.
The paper discusses how global changes in the industry, following the liberalisation of investment regimes, and mergers and strategic alliances between key firms, has, by virtue of the diffusion of new technology, led to further opportunities to prevent pollution and optimise future land use through planning for closure from the outset. The objectives and components of closure plans are also reviewed as the paper draws on case studies to highlight some of the possible constraints and challenges to pollution prevention that may be faced at the level of both public policy and corporate strategy. The article concludes by suggesting a forward-looking approach to integrated environmental management and viable future land-use planning based on a dynamic model for environmental management. 相似文献

As in many sectors in emerging economies, the concept of corporate social responsibility (CSR) has become important for exporting agri‐food firms in view of their integration in global supply chains. The purpose of this research was to assess the implementation by Chilean fruit exporters of CSR practices that go beyond minimum legal requirements. The principal results are that, although socio‐economic components of CSR such as poverty reduction and socially just working conditions receive much attention, firms consider comprehensive environmental practices as less important. The results also indicate a slightly higher implementation of comprehensive CSR practices by large firms as compared to small and medium sized enterprises (SMEs). The main conclusion is that, although CSR is increasingly considered by Chilean firms, among SMEs in particular, more attention needs to be paid to raising awareness among managers about CSR practices and to providing assistance in their implementation. This supports findings on CSR implementation in other emerging economies that an active role of civil society and industry organizations is key and that targeted support strategies are needed to install a holistic awareness of CSR and help firms to improve on those aspects of CSR that are relatively underdeveloped. 相似文献
