Biodiversity loss is a serious and ongoing global environmental problem. Economic instruments in biodiversity policies can contribute towards reconciling the conservation costs encountered at local level with the benefits of biodiversity conservation at higher levels of governance, from regional and national levels up to the global level. This paper outlines the theoretical foundations of fiscal transfers in conservation policies and also offers a concise account of existing international experience and future prospects. The recently amended Portuguese Local Finances Law (LFL) of 2007, with its groundbreaking new article on the promotion of local sustainability, is analysed in terms of the significance of fiscal transfers for municipal budgets. It is compared with its predecessor law, highlighting changes in fiscal revenues for selected municipalities in the country in relation to their designated conservation areas. The analysis shows that these ecological fiscal transfers can be significant for those municipalities with a large proportion of land under protected status. However, because it also introduces a considerable number of changes to the Portuguese fiscal transfer scheme, the ecological impact of the new LFL is difficult to grasp due to the presence of several crossover effects. The results obtained offer significant insights both for improving the Portuguese LFL and for designing new ecological fiscal transfer schemes. 相似文献

In the marginal, upland regions of the Philippines, soil erosion and poverty are significant problems. The Landcare Programme has sought to address these twin problems. We assess the economic impacts of the Landcare Programme in the Province of Bohol. We first explore whether the adoption of Landcare practices, particularly those of contour farming and tree planting, in a highly degraded landscape has resulted in improved livelihood outcomes for upland farming families. Second, we analyse the potential for the piecemeal adoption of these measures to deliver tangible benefits at the watershed scale. Finally, using a benefit–cost approach, these outcomes are compared with the costs of research and extension projects that have helped achieve them. We conclude that the net economic impact of the Landcare Programme in Bohol is positive, with the primary beneficiaries being the individual households that adopt the Landcare practices. These benefits are largely generated by productive opportunities that arise once the hillsides have been stabilized. Although the downstream impacts of land-use changes associated with the Landcare Programme are positive, they are of marginal economic importance. Hence, the focus and primary justification of the Landcare Programme should be on improving the productivity and livelihoods of upland farming households. 相似文献

In this paper an analysis of the U.K. government's air pollution emissions policy for the residential sector is undertaken. The analysis covers emissions arising from water and space heating, electric appliances and cooking appliances. Using an integrated economic-engineering model, the effects of the Energy Savings Trust and the imposition of Value Added Tax on residential fuel will be evaluated in terms of energy consumption and pollution emissions. It is found that the initial proposed policy was not sufficiently stringent to meet the government's environmental objectives, and that subsequent events have undermined the government's programme even further. Unless alternative policies are introduced, emissions from the residential sector will play an important role in jeopardizing the ability of the U.K. government to meet its international obligations. 相似文献

The year 2011 is the United Nations International Year of Forests. In addition to performing extremely significant environmental, economic, and social services, forests are also important tourism attractions in their own right and locations for recreation and tourism activities. The limited statistical data available suggest that there are billions of tourism and recreational visits to forests each year. This paper provides a global overview of biodiversity conservation, protected areas, recreational access, and management objectives in forests before outlining some of the main themes in the relationship between tourism and forests. It concludes that there is a need for a research effort on tourism and forests in order to provide greater recognition for the economic and environmental contributions of tourism in forest areas as well as the overall value of forests for health and wellbeing. 相似文献

Agriculture accounts for over half of Ethiopian GDP, yet 'he case for agriculture as a focus of economic growth strategies must rely on identifying a set of intersectoral linkages through which agricultural growth contributes to the growth of nonagriculture in the Ethiopian economy. This article develops a four-sector numerical simulation model of economic growth in Ethiopia which permits the calculation of macroeconomic growth multipliers resulting from income shocks to agriculture, services, modern industry, and traditional industry. The resulting growth multipliers are 1.54 for agriculture. 1.80 for services, 1.34 for modern industry, and 1.22 for traditional industry. These results depict an economy in which intersectoral linkages operate on a highly uneven basis. These limits are reflected in the wide disparity between sectoral growth multipliers and by substantial differences in the patterns ol their decomposition. The policy relevance of these findings relate, in part, to the distributional implications of growth in particular sectors. Poverty in Ethiopia is disproportionately rural. An income shock to agriculture is clearly the most progressive choice, indicating the need to highlight agricultural development in growth strategies for Ethiopia. Yet, the simulation results further indicate that doing so imposes relatively little trade off against total benefit. While a $1 service sector income shock generates $0.80 in indirect benefits, a $1 agricultural income shock still generates $0.54 in indirect gains-a somewhat smaller benelit, but one likely to make the greatest possible impact on poverty reduction. 相似文献

The current global wave of land acquisition – variously debated as land grabbing or investment in land – is promoted by the World Bank and the FAO as creating win–win-situations for local populations and investors alike. Common policy recommendations suggest expanding the production of export crops, by making use of marginal or unused land. Considerable potentials for such an expansion are assumed. Taking Tanzania as a case study, the evidence for such types of land is assessed by using a broad range of statistics. We will argue firstly, that the terms marginal and unused land serve as a manipulative terminology for the benefit of attempts to commercially valorize and commodify African landscapes, from biofuel to large-scale food production and tourism. However, they relate to different rationalities of domination. Unused land refers to a state-bureaucratic narrative, which excludes user groups deemed irrelevant for national development, while marginal land refers to a capitalist-economic narrative that excludes what is not profitable. Secondly, the terms are analyzed as categories central for state simplification of social relations attached to land. Modelling of these land use categories based on remote sensing is an attempt to compensate weak state capacities to enhance the legibility of the landscape by constructing it as a landscape of commercial value. 相似文献

The allocative efficiency and conservation potential of water laws encouraging investments in on-farm irrigation technology 总被引:3,自引:0,他引:3
Agricultural water conservation statutes are emerging in the West encouraging private irrigators to improve on‐farm irrigation efficiency as a basinwide conservation measure. We investigate whether private improvements promote the economic efficiency and conservation of water use basinwide under a wide variety of hydroeconomic circumstances. The standard of efficiency is how an irrigation district manager should optimally invest in improving the irrigation efficiencies of individual farms located along a stream while internalizing intrabasin allocative externalities of these investments. The results indicate that the popular Oregon legislative model may be the least effective in conserving water and promoting economically efficient water allocation. 相似文献
