The Mesta-Nestos river basin in Bulgaria and Greece is a case study for transboundary decision-making support in south-eastern Europe and a show-case for the development of methodologies and information-gathering for the integrated regional planning of water resources. Land-use conflicts in this water-scarce region cover a wide spectrum of activities like agricultural irrigation,drinking water production,diversions for industrial water,and risk of pollution from mining,to name a few examples. Measurements of the water quality were carried out in the upper basin. Results will be illustrated by the example of the environmental situation in the alpine region of the Pirin National Park as well as in the Razlog Basin with a stronger anthropogenic impact and pollution around a former uranium mine near the village of Ele?nica. The social and economic development of this transboundary region is a recently established priority for the future. It will mean an increase in water usage and more stress for the water resources if regional impacts of global climate change are verified. Problem-focused management of the catchment area as a whole on the basis of proved geo-data sets is needed for the future. 相似文献
Brazil is the first major developing country to pledge for absolute reductions in greenhouse gas emissions. This article explores the extent to which fiscal policies could contribute to this reduction and to greening the Brazilian economy. It was found that the use of green fiscal policies is at an early stage in Brazil, but a growing number of measures have been adopted in recent years led by subnational-level policies. An econometric analysis of 24 Brazilian manufacturing sectors for the years 2001–2008 shows that some fiscal instruments, such as low-cost (subsidized) finance for innovation and fiscal incentives for sustainable practices, have been effective in inducing green innovation. However, less than 14% of more than 100 thousand companies included in the study have adopted greener technologies. Even though Brazilian green fiscal policies have been rather uncoordinated and ad hoc, their significant impact on the uptake of green technologies indicates these can play an important role in a transition to a green economy.
POLICY RELEVANCE
Faced with the challenge of reducing its greenhouse gas emissions in absolute terms, Brazil now needs to put in place policies to help deliver the country’s pledge. This article analyses which fiscal policies should be adopted and how these policies could form part of a low carbon policy framework in the country. Among our policy-relevant findings is that subnational green fiscal policies are relatively less complex to introduce and encourage uptake of green technologies. Thus, they could be an entry point to a wider green fiscal policy strategy. We also found that fiscal incentives for green innovation projects can present more than proportional impact on the uptake of green technologies owing to positive feedbacks, increasing returns to scale and spill-overs. These are attractive features of green innovations to developing countries in addition to environmental benefits, as they favour the accumulation of indigenous technological capabilities that are critical for long-term technological and economic development. These lessons learned from green fiscal policies in Brazil are applicable to other developing countries. 相似文献
The effects of circular economy on biodiversity are poorly understood. This study provides observations on approaches for assessing circular economy and illustrates, with a Finnish case study, the potential of circular economy to mitigate pressures on biodiversity. The case study focuses on the construction and real estate sectors, as well as the forest industry. The findings imply that circular economy actions that reduce the extraction of virgin raw materials and relieve land use pressures are effective. Improving material efficiency, increasing the cascading use of wood, and optimizing the use and reuse of materials and products, as well as extending the lifetime of buildings and optimizing space use, have good potential for mitigating pressures on biodiversity in Finland. However, as forest utilization has a major impact on Finnish biodiversity, certain actions that possibly increase the use of forest resources (e.g., replacing fossil-based, concrete, or steel materials with wood-based solutions) may impair biodiversity if biodiversity-enhancing forest management practices are not utilized. Assessing the biodiversity impacts of circular economy is challenging, and the need for further research and the development of indicators and assessment methods is clear. 相似文献
