食品安全许可证制度研究

食品安全许可证制度是指在食品的生产和流通过程中,为预防和减少食品安全事故,保护公民的生命安全和身体健康,保护国家和人民财产,依法享有食品行政许可监管职能的行政主体依照法律规定的权限和程序,对食品的生产和流通进行干预和控制的行为。然而,我国现阶段的食品安全许可证制度并不完善,导致食品安全事故频发,这已俨然成为关系到国计民生的社会问题。完善食品安全许可证制度,对我国构建和谐社会,创建服务型政府和保障社会公共利益都具有重大意义。

Delivery system performance case study: Wellton-Mohawk irrigation and drainage district,USA

An irrigation district in southwestern Arizona was studied to assess the performance of its water delivery system. Data were obtained through monitoring of lateral canals, examining water order reports and bills, and conducting a diagnostic analysis of the water delivery and on-farm irrigation systems through interviews. A number of differences between official andde facto district operating policies were found. These policies had changed over the years and provided far more flexibility and better service than provided by the original official policy. The canal system, which was designed to be operated under upstream control, was found to be operated under a complex mixture of manual upstream and downstream control that resembled dynamic regulation. Farmers made official (recorded) water orders only about half the time. Deliveries usually occurred within one day of the ordered date, as per district policy, with more late deliveries at the tail end of the system during peak water use periods. On average, the district delivered the rate and duration ordered, but average flow rates for individual deliveries were not accurately estimated due to fluctuating flows. The two biggest shortfalls observed were the lack of water measurement records at intermediate points in the system and lack of thorough water accounting. These shortfalls appeared to have had only a minor effect on overall district objectives.

An expert system for the management of Botrytis cinerea in Australian vineyards. II. Validation

An expert system developed by Ellison et al. (1997) for the management of Botrytis cinerea in Australian vineyards was validated against actual vineyard practices and official recommendations for control of the pathogen, using historical test cases from grapegrowing regions in southern New South Wales and from the Riverland region of South Australia. Performance of the expert system was judged on its ability to reduce unnecessary spray applications in seasons free from disease and to improve the timing of spray applications when conditions favoured disease development. In the test cases where disease did not develop, the expert system recommended between two and five sprays. This was comparable to the number of recommendations by official sources of advice but was excessive compared to actual vineyard practice where no sprays were applied. Reasons for the over-recommendation of sprays by the expert system were proposed. In the test cases where B. cinerea was observed, the expert system recommended a comparable number of sprays to grower practice and fewer sprays than official sources. With regard to timing of spray applications, the expert system was the only source of knowledge where spray recommendations bore any relationship to critical periods in the epidemiology of B. cinerea. Problems encountered in the validation of the expert system are discussed.

Water distribution on a large distributary,Tungabhadra, India

Results are presented of field research on water distribution in the command area, covering 18,200 ha, of a secondary irrigation canal in the Tungabhadra Left Bank Scheme, Karnataka State, India.The official objective of the Scheme and the resulting implications for the water distribution are discussed first. An explanation of the planning and operation of the water distribution follows.The results are based on analyses of the water flows taken from the D36 secondary canal and distributed along the canal to the pipe outlets (inlet structures to the tertiary units), and of the canal section rotation practised along the canal. The analyses concentrate on three dimensions of the water supply:The design flows, according to the official Scheme objectives and criteria;The targets, as set by the system operators before every season;The actual distribution procedures and flows, as observed during the operation.The analyses, supported by flow measurement data, illustrate that the water distribution is not based on consistent and clear criteria and procedures, but that it is the outcome of varying compromises, decided upon pragmatically by the field staff, to bridge the gap between the farmers' demands and the upstream constraints to water availability. This paper explains the widespread phenomenon of head reaches taking too much water, leaving little or nothing for the tail end of the canal.

Cost data yielded some important comparisons. Unreinforced concrete was the choice of O&M personnel in frost-free regions with choice in heavy-frost areas dependent on water table and soil type.The views expressed in this paper are those of the author and are not presented as official or unofficial views of the World Bank.     

Strategy for Efficient Energy Management to solve energy problems in modernized irrigation: analysis of the Spanish case

While the modernization of irrigation techniques in recent years has improved water use efficiency, the substitution of open channels by pressurized pipes led to a substantial increase in the energy used in irrigated agriculture. Given the concern for energy savings and sustainability, official administrations have promoted several initiatives to improve energy efficiency in irrigated agriculture, and researchers have developed different tools for the same. Although energy audits have been conducted in irrigation networks managed by Water Users’ Associations, the implementation of energy conservation measures proposed in these audits has not been always successful. This paper, which reviews the energy aspects of irrigation systems modernized in recent decades in Spain and in other countries, considers the characteristics and special features of Water Users’ Associations and proposes an energy management system (EMS) for the same. The stages of the EMS are described, beginning with the definition of energy policy and the establishment, implementation and verification of energy plans, the essential conditions to guarantee the success of the EMS are described, in which energy audits are just a part of a process of continual improvement of energy efficiency. A Strategy for Efficient Energy Management has been implemented in a Water Users’ Association in southeast Spain. The improvement measures proposed in the first energy plan were implemented, and an increase from 60 to 65 % in average energy efficiency was achieved.     

Estimating groundwater withdrawals in areas of intensive agricultural pumping in central Spain

Measuring groundwater extractions is central to adequate groundwater management in agricultural basins. Groundwater pumping records are often subject to considerable uncertainties, particularly in the case of arid and semiarid settings where irrigation is the most important water use. In most cases this is due to the difficulties involved in locating and monitoring all wells. We describe the estimation of groundwater pumping by coupling the water table fluctuation method with the groundwater balance equation. This is demonstrated through its application to the Mancha Occidental aquifer, Spain, an area subject to intensive pumping for irrigation since the early 1970s. A sensitivity analysis is conducted to evaluate the effect of relevant hydrogeological parameters, namely specific yield, as well as the most appropriate theoretical semivariogram, to calculate yearly storage variations within the system. Results are validated in the light of official pumping estimates.
