Nepal is considered a leader among developing nations with regard to conservation legislation and programs; it was among the
first Asian nations to develop national conservation legislation, sign CITES, and develop a national conservation strategy.
We review the history of modern conservation law in Nepal from the Rana period (early 1950s) to the present. The early legislation
focused mainly on strict preservation of areas and species; this phase culminated in the National Parks and Wildlife Conservation
Act of 1973. Subsequent legislation has evolved more in the direction of an integrated, holistic approach to conservation
and is beginning to incorporate the participation of local people; subsequent amendments to the 1973 act allowed greater rights
to rural villagers, and the designation of conservation areas in addition to the more strictly defined protected areas (national
parks, wildlife reserves, etc.).
Our review of conservation legislation suggests that Nepal has had many successes to date; the country has a protected area
system covering over 10% of its land area, and many target species are recovering in parks and reserves. There are also some
causes of concern, including staff shortages, financial constraints within the Department of National Parks and Wildlife Conservation,
and the fact that there is little legal infrastructure outside of protected areas to enforce conservation laws; further, some
aspects of hunting regulations are in need of revision. Primary needs include a comprehensive review of these policies and
a nationalized strategy to ameliorate the shortcomings. 相似文献

In China, the use and obsolescence of both electronic and electrical equipment have increased rapidly in recent years. China
has also begun to take measures to cope with this problem since it began experiencing a rapid process of industrialization
and urbanization in the 1990s. In this paper, the profile of the electrical and electronic waste (e-waste) problem in China
is depicted from such aspects as domestic e-waste and imported e-waste, along with their recycling systems, policies, and
regulations. Based on statistics of the consumption of major household appliances and personal computers, a forecast is made
of the numbers of obsolete major household appliances and personal computers. The results show that currently the number of
electrical and electronic products in use in China is tremendous. An investigation on household appliances and personal computers
in Beijing was made to assess the use and obsolescence of these products. Also, the legal issues relating to e-waste in China
are summarized, and these will be the juristic foundation for the solution of e-waste problems. 相似文献

In his recent article, Cairncross identified problems with legislation relevant to the conservation of national geological heritage. This permits us to pose some more general questions, which are not addressed in the noted contribution. The example given by Cairncross indicates some pitfalls linked with the “all-inclusive” nature of legislation in which geological heritage is mixed with cultural heritage. Are such laws really helpful? Even if they are inevitable, they should be prepared with great caution. Moreover, it appears sensible to discuss whether particular geological objects or geodiversity as a whole should be legally conserved. Cairncross also proposes the interesting idea of a special fund/agency for purchasing rare mineral specimens for museums. This raises a set of questions about selection criteria for minerals to be purchased, types of market to be dealt with, number of fund/agency staff, necessary financial resources, and the administration of such purchasing schemes. Broad multi-stakeholder debates are necessary in order to establish the proposed fund/agency and to facilitate its efficient work. 相似文献

Problem
Enforced primary seatbelt laws can reduce morbidity and mortality associated with motor-vehicle crashes. Constituent support is an important factor associated with legislator voting behavior toward injury prevention laws. Little is known about attitudes toward a primary seat belt law among adults in rural states without a primary seat belt law.Methods
Data from the Behavioral Risk Factor Surveillance System (BRFSS) survey, a telephone survey of a representative sample of adults in Montana, were used to assess attitudes toward a primary seat belt law.Results
Sixty-one percent of respondents supported a primary seat belt law. Using multiple logistic regression analyses, women (AOR 1.87; 95% CI 1.49-2.36), persons aged 65 years and older (1.45; 1.06-1.96), American Indians (2.71; 1.55-4.75), those with health insurance (1.51; 1.07-2.14), and those who reported always wearing their seat belt (4.05; 3.14-5.21) were more likely to support a primary seat belt law than respondents without these characteristics.Conclusions
The majority of adults in a rural state support a primary seat belt law. 相似文献57.

Coastal area management should be considered as an element of a more general philosophy—that of natural resource management—which
is in the process of replacing the purely ‘protection of the environment’ approach which was dominated most of the 20th century.
Specific legislation on coastal management has been adopted by many countries, and today steps have been taken to acumulate
all experience accumulated and to harmonize legal regulations on the international level. For the Russian Federation, formerly
the Soviet Union, with an enormous sea-shore line to cope with, it is a new experience to develop a concept and a legal regulation
specifically tackling coastal area management. The draft of a legislative act on coastal area management reflects the attempts
to find ways for harmonizing various economic, environmental and social interests in this huge area, encompassing relevant
Russian legislation in force as well as international conventions and treaties, and taking into considerations and treatices,
and taking into consideration foregin expereience in this field. 相似文献

Wastewater irrigation is an environmentally sound wastewater disposal practice, but sewage is more saline than the supplied fresh water and the salts are recycled together with the water. Salts have negative environmental effects on crops, soils, and groundwater. There are no inexpensive ways to remove the salts once they enter sewage, and the prevention of sewage salt enrichment is the most immediately available solution. The body of initiatives presently structured by the Ministry of the Environment of Israel are herein described, with the aim to contribute to the search for a long-term solution of salinity problems in arid countries. The new initiatives are based on: (1) search for new technologies to reduce salt consumption and discharge into sewage; (2) different technologies to cope with different situations; (3) raising the awareness of the public and industry on the environmental implications of salinity pollution; and (4) an elastic legal approach expressed through new state-of-the-art regulations. The main contributor to the salinity of sewage in Israel is the watersoftening process followed by the meat koshering process. Some of the adopted technical solutions are: the discharge of the brine into the sea, the substitution of sodium by potassium salts in the ion-exchangers, the construction of centralized systems for the supply of soft water in industrial areas, the precipitation of Ca and Mg in the effluents from ion-exchangers and recycling of the NaCI solution, a reduction of the discharge of salts by the meat koshering process, and new membrane technology for salt recovery. 相似文献
