This article aims to highlight the current status of compliance to Machinery Directive 98/37/EC (transposed to Spanish regulation as RD 56/1995, of 20th January) (a new directive numbered as 2006/42/EC [Directive 2006/42/EC of the European Parliament and of the Council of 17 may 2006 on machinery, and amending Directive 95/16/EC (recast). OJ L157/24-86, 9.6.2006.], that recasts and replaced 98/37/ED directive and its amendments, came into force on 29 June 2006; it will not be applied until 29th December 2009. European Member States have a lead-time of two years to adopt and publish the national laws and regulations transposing the provisions of the new Directive into national law. Latest 10th October, Spain transposed Machinery Directive 2006/42/EC to national regulation as Real Decreto 1644/2008 [Real Decreto 1644/2008, de 10 de octubre, por el que se establecen las normas para la comercialización y puesta en servicio de las máquinas. BOE 246/2008, de 11 octubre 2008. Páginas 40995–41030]) of a particular family of machinery (hand-held, medium and small-size, deeply introduced in the market, of low-medium cost), that any user, professional or non-professional, can acquire as first-hand in any of the sales points (whether or not experts in these kind of products).At the same time, it emphasises the most significant shortcomings and non-conformities found, after analyzing the results of five consecutive Campaigns of Control of Industrial Products performed by one of the labs (placed in Spain) involved in the market surveillance European Program. 相似文献

The Expansion of Farm-Based Plantation Forestry in Vietnam 总被引:2,自引:0,他引:2
This study targets plantation forestry by farm households (small holders), which is increasing globally and most rapidly in
China and Vietnam. By use of an interdisciplinary approach on three study sites in Vietnam, we examined the trends in farmers’
tree planting over time, the various pre-requisites for farm-based plantation forestry and its impact on rural people’s livelihood
strategies, socio-economic status, income and security. The findings indicated a change from subsistence to cash-based household
economy, diversification of farmers’ incomes and a transformation of the landscape from mainly natural forests, via deforestation
and shifting cultivation, to a landscape dominated by farm-based plantations. The trend of transformation, over a period of
some 30 years, towards cash crops and forestry was induced by a combination of policy, market, institutional, infrastructural
and other conditions and the existence of professional farming communities, and was most rapid close to the industrial market. 相似文献

Research on the benefits of local ecological knowledge for conservation lacks empirical data on the pathways through which
local knowledge might affect natural resources management. We test whether ethnobotanical skills, a proxy for local ecological
knowledge, are associated to the clearance of forest through their interaction with agricultural labor. We collected information
from men in a society of gatherers–horticulturalist, the Tsimane’ (Bolivia). Data included a baseline survey, a survey of
ethnobotanical skills (n = 190 men), and two surveys on agricultural labor inputs (n = 466 plots). We find a direct effect of ethnobotanical skills in lowering the extent of forest cleared in fallow but not
in old-growth forest. We also find that the interaction between ethnobotanical skills and labor invested in shifting cultivation
has opposite effects depending on whether the clearing is done in old-growth or fallow forest. We explain the finding in the
context of Tsimane’ increasing integration to the market economy. 相似文献

As in other mountain regions of Asia, agricultural lands in the Chittagong Hill Tracts (CHT) of Bangladesh are undergoing
degradation due primarily to environmentally incompatible land-use systems such as shifting cultivation (jhum) and annual cash crops. The suitable land-use systems such as agroforestry and timber tree plantation provide benefit to
the society at large, but they might not provide attractive economic benefits to farmers, eventually constraining a wide-scale
adoption of such land-use systems. Therefore, it is essential to evaluate agricultural land-use systems from both societal
and private perspectives in the pursuit of promoting particularly environmentally sustainable systems. This article evaluated
five major land-use systems being practiced in CHT, namely jhum, annual cash crops, horticulture, agroforestry, and timber plantation. The results of the financial analysis revealed the
annual cash crops as the most attractive land use and jhum as the least attractive of the five land-use systems considered under the study. Horticulture, timber plantation, and agroforestry,
considered to be suitable land-use systems particularly for mountainous areas, held the middle ground between these two systems.
Annual cash crops provided the highest financial return at the cost of a very high rate of soil erosion. When the societal
cost of soil erosion is considered, annual cash crops appear to be the most costly land-use system, followed by jhum and horticulture. Although financially less attractive compared to annual cash crops and horticulture, agroforestry and timber
plantation are the socially most beneficial land-use systems. Findings of the alternative policy analyses indicate that there
is a good prospect for making environmentally sustainable land-use systems, such as agroforestry and timber plantation, attractive
for the farmers by eliminating existing legal and institutional barriers, combined with the provision of necessary support
services and facilities.

Current “business as usual” projections suggest greenhouse gas emissions from industrialized nations will grow substantially
over the next decade. However, if it comes into force, the Kyoto Protocol will require industrialized nations to reduce emissions
to an average of 5% below 1990 levels in the 2008–2012 period. Taking early action to close this gap has a number of advantages.
It reduces the risks of passing thresholds that trigger climate change “surprises.” Early action also increases future generations'
ability to choose greater levels of climate protection, and it leads to faster reductions of other pollutants. From an economic
sense, early action is important because it allows shifts to less carbon-intensive technologies during the course of normal
capital stock turnover. Moreover, many options for emission reduction have negative costs, and thus are economically worthwhile,
because of paybacks in energy costs, healthcare costs, and other benefits. Finally, early emission reductions enhance the
probability of successful ratification and lower the risk of noncompliance with the protocol. We discuss policy approaches
for the period prior to 2008. Disadvantages of the current proposals for Credit for Early Action are the possibility of adverse
selection due to problematic baseline calculation methods as well as the distributionary impacts of allocating a part of the
emissions budget already before 2008. One simple policy without drawbacks is the so-called baseline protection, which removes
the disincentive to early action due to the expectation that businesses may, in the future, receive emission rights in proportion
to past emissions. It is particularly important to adopt policies that shift investment in long-lived capital stock towards
less carbon-intensive technologies and to encourage innovation and technology development that will reduce future compliance
costs. 相似文献
