And Performance

Adaptive management has been promoted as a structured approach to learning in response to the uncertainty associated with managing complex systems. We developed and tested a protocol to guide an adaptive approach to water quality management in north-eastern Australia. The protocol articulates a framework for documenting uncertainties and performance expectations, negotiating feedback and anticipating iterative and transformative responses to future scenarios. A Water Quality Improvement Plan developed for the Tully–Murray catchment in the Great Barrier Reef region was used to test the protocol and three benefits of its use were identified. First, developing rigorous and timely monitoring and evaluation ensures that opportunities for iterative planning are realised. Second, anticipating future endogenous or exogenous changes to the plan enables the early initiation of actions to inform transformative planning responses. Finally, the protocol exposed the need to coordinate multi-scalar responses to tackle environmental knowledge and management uncertainties and assumptions. The protocol seeks to provide a practical translation of adaptive planning theory that will enable the benefits of adaptive management to be realised on the ground.

The Individual

The Great Barrier Reef (GBR) is a protected ecosystem, listed as a UNESCO World Heritage site since 1981. It runs for approximately 3000km along the coastline in north-eastern Australia. A total of thirty-five major river basins discharge to the GBR and many transport large loads of pesticides, suspended sediment, nutrients from agricultural land. Over the past 6 years an extensive program has been conducted by the Queensland Government to monitor concentrations of 51 pesticides and their breakdown products in 17 rivers that discharge to the GBR. To explore the potential impact that the pesticides pose to the riverine environments and to the GBR we analysed the risk posed by the individual pesticides and their mixtures. Australia currently does not have water quality guidelines for 17 of the 38 pesticides detected. For those, we calculated ecotoxicity thresholds using a simplified version of the Australian methodology for determining water quality guideline values, based on species-sensitivity distributions. In all rivers, multiple pesticides were routinely detected at concentrations greater than their level of reporting. All rivers had at least one sample where the combined toxicity was greater than 1 toxic unit (TU), i.e. exposure situations where the total pesticide concentration exceeded acceptable levels. In a number of rivers more than 50% of samples had a combined toxicity greater than 1 TU. Average TU’s per river ranged from 13.47 to 0.10, with substantial fluctuations over the seasons but without clear trends between years. The patterns indicate that specific events such as severity of wet/dry seasons and cyclone events impact the combined toxicity found. We also found land use patterns affected the combined toxicity in the river ecosystems. In each of the rivers, 90% of the expected mixture toxicity was caused by only between 2 and 6 pesticides, although the individual pesticides that dominated the combined toxicity differed between rivers.

And Performance

Total-reflection X-ray fluorescence spectrometry, abbreviated as TXRF, is known for its high sensitivity down to the low pg-level or sub-ppb level, respectively, and its wide dynamic range of about three to four orders of magnitude (Yoneda and Horiuchi, 1971, Wobrauschek and Aiginger, 1980; Knoth and Schwenke, 1978 and 1980, Aiginger and Wobrausohek, 1985, Michaelis et al., 1985, Prange, 1987). Meanwhile several laboratories have purchased commercially available TXRF spectrometers and have started to report favourable about this technique. Applications have been reported from various disciplines: These are estuarine and marine water quality management and research, air pollution studies, mineralogical investigations, biology and medicine (Prange, 1987, Prange et al, 1985; Prange and Kremling, 1985, Prange et al., 1987, Stöβel and Prange, 1985, Michaelis, 1986, Ketelsen and Knöchel, 1985, Leland et al., 1987, von Bohlen et al., 1987, Junge et al., 1983, Hentschke et al., 1985, Hentschke et al., 1985, Gerwinski and Goetz, 1987, von Bohlen et al., 1987), In spite of its close kinship to conventional EDXRF , TXRF is quite different with respect to operation and performance and provides complementary capabilities.

The Way

A commitment to proactively manage, operate, and provide the necessary services for support of a high-occupancy vehicle (HOV) system is needed so that all HOV facilities can meet intended objectives and performance expectations. This operational focus should be integrated into all phases of an HOV system, from the strategic system planning through the ongoing performance monitoring and evaluation of specific facilities. The ongoing performance monitoring and evaluation of HOV facilities should be the basis for making continuous incremental changes in the way the system is managed, the way facilities are operated, and the way that support programs and services are utilized. HOV facilities are not appropriate in every location, and conditions change over time. Changes may warrant continuous adjustments or significant revisions in HOV facility operation. Before proposal of any significant changes in operation, all relevant factors, interests, alternatives, and associated impacts should be considered and analyzed in detail. These operational alternatives should include incremental revisions to improve the performance of the HOV system or specific facilities. Significant operational changes should be considered only after all possible incremental adjustments have been made to improve the performance of the existing HOV lane. In accepting federal aid, agencies have agreed to manage, operate, and maintain HOV facilities as they were originally planned, designed, constructed, and approved. Situations in which a federal review of operational changes to HOV facilities is required, the information needed to support such a review, and the existing federal requirements against which this review will be completed are identified. A review of the important issues and possible impacts resulting from any significant operational change is needed so as to determine whether federal approval is required and to assure consistency with the federal aid program provisions of 23 U.S.C. and 49 U.S.C.

Decentralised approaches to water governance have emerged as a common approach to tackle complex environmental management issues in Australia and elsewhere. While decentralisation offers hope for a more holistic, integrated and effective approach to environmental planning decisions and solutions, challenges remain to put these ideals into practice. The present paper focuses on a key component of this approach to environmental planning and decision-making – the integration of different types of knowledge used to inform planning goals and the design of water quality management programs. The analysis draws on knowledge integration issues surrounding the water quality improvement plan in the Tully–Murray basin in north-eastern Australia. Here, government and non-government stakeholders are coordinating efforts to assess water quality condition and set management priorities for improving the quality of water entering the Great Barrier Reef World Heritage coastal lagoon. Our analysis of the kinds of knowledge and mechanisms of translation involved highlights three main points. First, the tensions between the uncertainty and bias in different types of knowledge brought to the planning table. Second, the timing of knowledge contributions that affects if and how knowledge contributions can be debated and integrated. Finally, the challenges faced by local collaborative groups to broker the translation and integration of knowledge needed to inform strategic environmental decisions and programs.

This research aims to design 5R character-based halal industry players (Ringkas, Rapi, Resik, Rawat, Rajin) or 5S (Sort, Set in Order, Shine, Standardize, Sustain), as well as their debriefing for UNY and IIUM students in supporting the Halal industry related to Good Aquaculture Practices. This area has been selected, due to some factors. The first is the occurrence of several cases of aquaculture products that changed status from being permissible to become impermissible due to the external factors, for example, the fact that the water quality is bad and contaminated with harmful chemical substances. Water quality is the most important factor affecting fish health and performance in aquaculture production system. Secondly the fish nutrition and feeding are mixed with unclean and filthy ingredients. Thirdly, it is exposed to the risk of contamination from the equipment, which eventually affects halal integrity. Halal products cannot be prepared, processed, or manufactured using equipment that is contaminated with non-halal substances (unclean defined by Shariah). Contamination can be caused by equipment that is contaminated or used together with non-halal products. Therefore, equipment and machinery used in the halal aquaculture industry play a very important role to ensure halal integrity. This paper uses a library and literature review approach. It is expected that with the arrangement of 5R or 5S-based character strengthening design, the operators of Aquaculture Industry may preserve Halal Supply Chain.
