Coastal ecosystems worldwide are under pressure from human-induced nutrient inputs, fishing activities, mariculture, construction work, and climate change. Integrated management instruments handling one or more of these problems in combination with socioeconomic issues are therefore necessary to secure a sustainable use of resources. In the Limfjord, a temperate eutrophic estuary in Denmark, nutrient load reductions are necessary to fulfill EU regulations such as the Water Framework Directive (WFD). The expected outcome of these load reductions is an improved water quality, but also reduced production of the abundant stock of filter-feeding blue mussels, Mytilus edulis. This is expected to have significant economic consequences for the million-euro mussel...

The Adaptive Decision-Making Process as a Tool for Integrated Natural Resource Management: Focus, Attitudes, and Approach

Lal, Padma; Australian National University; padma.lal@anu.edu.au; Lim-Applegate, Hazel; Australian National University; hlim_manila@hotmail.com; Scoccimarro, Michelle C; Australian National University;.

Integrated natural resource management (INRM) and its many closely related approaches are generally considered to be more effective than single-disciplinary approaches for managing the complex resource issues currently facing many countries. INRM approaches aim to integrate several disciplines and involve different stakeholders operating in their own subsystems across different spatial and temporal scales. These approaches focus on identifying management strategies for sustaining natural resource stocks and flows of goods and services as well as their underlying ecological processes. Changes in the behavior of consumers and producers and in the allocation of resources among uses, users, time, and space will be necessary to achieve sustainable development....

Environmental Flows: Striking the Balance between Development and Resource Protection

King, Jackie; University of Cape Town; Jackie.King@uct.ac.za; Brown, Cate; Southern Waters Ecological Research and Consulting;.

Management of scarce water resources through the use of environmental flows, particularly in developing countries in data-poor arid areas, raises many scientific challenges. These include transforming hydrological data into an ecologically relevant format, providing quantified predictions of river responses to flow change, describing the impacts of river change on common-property users of the rivers, providing the information in a format that decision makers can use, and guiding monitoring and adaptive management. Each of these challenges emerged in South Africa during the last two decades, when rivers and other aquatic ecosystems were enhanced in stature from having no rights to their own water to being one of only two sectors with a right to water; the...

Stakeholder participation is becoming increasingly important in water resources management. In participatory processes, stakeholders contribute by putting forward their own perspective, and they benefit by enhancing their understanding of the factors involved in decision making. A diversity of modeling tools can be used to facilitate participatory processes. Bayesian networks are well suited to this task for a variety of reasons, including their ability to structure discussions and visual appeal. This research focuses on developing and testing a set of evaluation criteria for public participation. The advantages and limitations of these criteria are discussed in the light of a specific participatory modeling initiative. Modeling work was conducted in the...

Integrated pest management (IPM) and Internet-based information delivery systems

Neotropical Entomology

Bajwa,Waheed I.; Coop,Leonard; Kogan,Marcos.

The Internet enables collaboration and information sharing on an unprecedented scale. It has become a prime medium for research and extension communication. The World Wide Web (WWW) makes it possible to combine information from many different sites in a seamless fashion. The potential for using the web to integrate all types of static and interactive (dynamic) information is unique and unprecedented. The web provides excellent interfaces for all kinds of interactive network databases, and many kinds of online analyses and data processing. Web-based models and decision support systems (DSS) are becoming popular because little or no client software is required, thus reducing software management and distribution costs. No other medium offers such ability as...

An imbalance of quantitative information on pest and disease impacts hampers biosecurity decision-making; there is relatively good information about impacts on industry, but relatively poor information about how society values the impacts on indigenous biodiversity. A benefits transfer process based on a database of choice experiments could help to redress this imbalance. This paper: briefly reviews four choice experiments that will be the foundation of a database; reviews benefit transfer literature; and sets out framework ideas for a Decision Support System (DSS), which will incorporate biodiversity values via a process for benefit transfer to facilitate more informed biosecurity decisions.

Water management has evolved in the last years towards more integrated and participatory approaches, aiming at improving the adaptability of water systems. Following this line, we propose a methodology to build a decision support system, based on the participation of stakeholders and the integration of the different disciplines involved in water use, as well as the inclusion of uncertainties in the management planning. The process has been implemented in the Upper Guadiana basin (Spain) with the aim of solving the existing conflicts: the aquifer, which is the main water source in the area, has been over-exploited during the last decades for irrigation. This has lead to serious degradation of natural water-related ecosystems and important social conflicts....

Economic Consequences of Biological Variation: The Case of Mycoplasma in Swine Herds

Otto, Lars.

We present an economic decision support model, based on a Bayesian network, for Mycoplasma infection in slaughter swine production. The model describes the various risk factors for Mycoplasma infection and their interactions. This leads to a stochastic determination of the consequences of productivity factors, and this again results in stochastic economic consequences when changing the risk factors or engaging in control arrangements. We use the model to calculate how estimated prevalence and level of Mycoplasma changes when we gather evidence from various veterinarian examinations, and we show how this influences the distribution of the economic results of a change in strategy to fight Mycoplasma. One result is that the profitability in fighting...

ABSTRACT The objective of this study was to simulate total dry matter intake and cost of diets optimized by nonlinear programming to meet the nutritional requirements of dairy does and growing doelings. The mathematical model was programmed in a Microsoft Excel(r) spreadsheet. Increasing values of body mass and average daily weight gain for growing doelings and increasing body mass values and milk yield for dairy does were used as inputs for optimizations. Three objective functions were considered: minimization of the dietary cost, dry matter intake maximization, and maximization of the efficiency of use of the ingested crude protein. To solve the proposed problems we used the Excel(r) Solver(r) algorithm. The Excel(r) Solver(r) was able to balance diets...

ABSTRACT Capacity planning in agricultural field operations needs to give consideration to the operational system design which involves the selection and dimensioning of production components, such as machinery and equipment. Capacity planning models currently onstream are generally based on average norm data and not on specific farm data which may vary from year to year. In this paper a model is presented for predicting the cost of in-field and transport operations for multiple-field and multiple-crop production systems. A case study from a real production system is presented in order to demonstrate the model’s functionalities and its sensitivity to parameters known to be somewhat imprecise. It was shown that the proposed model can provide operation cost...
