Ricardo Braun 《Environment, Development and Sustainability》2007,9(4):387-411
The implementation of sustainable development may seem a simple concept when written on paper. However to carry-out long term
actions put forward by the Agenda 21 (AG21) at the local level represents one of the main challenges as municipal governments
in general do not have the capacity to effectively implement the process.
Regional environmental assessment (REA) has shown to be effective in supporting decision-making not only to correct environmental
problems due to past unsustainable social-economic developments but also help local governments to implement sustainable actions.
However this requires long-term investments of AG21 plans and projects. The allocation of regular and consistent financial
resources is one of the main ingredients for the sustainable development process. But traditional plans and projects financed
by national and/or international funds may not be sustainable in the long-term because they become dependent on external funding.
Research demonstrate that innovative economic instruments such as ecotaxes represent a feasible alternative to sponsor local
sustainability because taxes are collected permanently by the government and could be invested in continuous actions. Ecotaxes
experiences have provided important reference to structure a municipal incentive model (MIM) to sponsor AG21’s environmental
plans and projects on a long-term (permanent) basis.
However sustainable development cannot be solely through economic investments. A comprehensive municipal environmental management
scheme (MEMS) has been established to support the incentive model. The scheme seeks not only to improve local institutional
framework but also incentive continuous participation of local stakeholders at all levels of society. Participatory events
and the provision of incentives (educational and financial) are key to motivate society to protect the environment and support
actively the sustainable development process as emphasised in the RIO-92 Conference. 相似文献

曲霉对水中重金属的吸附去除 总被引:15,自引:0,他引:15
利用2种曲霉A.sojae M146和A.oryzae M149的菌体,作为吸附剂对水中Pb^2+和Cd^2 进行去除实验。结果表明,曲霉菌体的最佳培养时间为72h,吸附的最佳pH为5.5、温度为30℃、时间为1h。在最佳实验条件下,A.sojae M146对Pb^2 和Cd^2 的吸附率,分别为69.76%和72.28%;A.oryzae M149对Pb^2 和Cd^2 的吸附率,分别为60.64%和81.34%。使用稀碱溶液对曲霉菌体进行浸泡预处理后,可提高对重金属的吸附去除效果;而使用稀释、乙醇水溶液以及蒸馏水对菌体浸泡后,明显降低了重金属的去除效果。Na2CO3和EDTA溶液,可以有效地将重金属从曲霉体上解吸下来,从而达到重复利用菌体作为吸附剂的目的。 相似文献

Can Forest-protection carbon projects improve rural livelihoods? Analysis of the Noel Kempff Mercado climate action project,Bolivia 总被引:1,自引:0,他引:1

We studied the Noel KempffMercado Climate Action Project (NKMCAP),Bolivia, to assess whether forestprotection carbon (C) projects cansignificantly benefit local people. Wehypothesized that forest protection canonly securely deliver C if significantstakeholders are meaningfully andtransparently involved, traditional orcustomary rights are recognized and theirloss compensated for, and there are directlinkages between conservation anddevelopment objective. Our researchfocused on 53 members of the communities ofFlorida, Porvenir and Piso Firme and 36secondary stakeholders. In each of thevillages we held half-day meetings withcommunity leaders, complemented bysemi-structured one-hour interviews with 5,10, and 7 families, representing 20%, 10%and 8% of each community. The long-termimpact of the NKMCAP on the localcommunities may well be positive. However,in the short run, certain sections of thelocal communities are financially poorer. Forest protection projects clearly have thepotential to sequester C, protectbiodiversity and simultaneously contributeto sustainable rural development, but ifthey really are to improve rurallivelihoods, they must be designed andimplemented carefully and participatively. 相似文献

The Lawrence Berkeley National Laboratory (Berkeley Lab) and the Center for Sustainable Development in the Americas (CSDA)
conducted technical studies and organized two training workshops to develop capacity in Central America for the evaluation
of climate change projects. This paper describes the results of two baseline case studies conducted for these workshops, one
for the power sector and one for the cement industry, that were devised to illustrate certain approaches to baseline setting.
Multiproject baseline emission rates (BERs) for the main Guatemalan electricity grid were calculated from 2001 data. In recent
years, the Guatemalan power sector has experienced rapid growth; thus, a sufficient number of new plants have been built to
estimate viable BERs. We found that BERs for baseload plants offsetting additional baseload capacity ranged from 0.702 kgCO2/kWh
(using a weighted average stringency) to 0.507 kgCO2/kWh (using a 10th percentile stringency), while the baseline for plants
offsetting load-following capacity is lower at 0.567 kgCO2/kWh. For power displaced from existing load-following plants, the
rate is higher, 0.735 kgCO2/kWh, as a result of the age of some plants used for meeting peak loads and the infrequency of
their use. The approved consolidated methodology for the Clean Development Mechanism yields a single rate of 0.753 kgCO2/kWh.
Due to the relatively small number of cement plants in the region and the regional nature of the cement market, all of Central
America was chosen as the geographic boundary for setting cement industry BERs. Unfortunately, actual operations and output
data were unobtainable for most of the plants in the region, and many data were estimated. Cement industry BERs ranged from
205 kgCO2 to 225 kgCO2 per metric ton of cement. 相似文献

Major mining companies have recently embraced the sustainable development paradigm, in seeking to improve their competitiveness and increase shareholder returns. Successful mine closure is one important element of this process. Improved performance in this area is essential if surrounding communities are to see mining companies as responsible corporate and social partners.
In Indonesia, the new approach has coincided with the development of specific mine closure legislation. To facilitate the legislation, a consortium of mining companies joined to form the Industry Mine Closure Steering Committee. This Committee has lobbied the Government, actively negotiating to incorporate sustainable development ideals and practices into the new legislation. The Committee's aim has been to foster continued development of the mining industry, while taking account of variation in environmental, social and community conditions. In describing the process, this article seeks to provide guidance for the development of mine closure legislation in other nations. 相似文献
