AbstractWe developed a discrete and qualitative model of integrated socio-ecosystems, with the help of formal Petri nets. We illustrated such Petri nets in the case study of temporary marshes in the Mediterranean part of France, the Camargue delta, by integrating biotic, abiotic and human-related components along with their processes into the same interaction network. The model demonstrated that when marshes are exposed to extensive grazing the presence of marsh heritage species is facilitated by opening up the vegetation through various trajectories. This supports the commonly used management practice of extensive grazing to conserve certain protected habitats. With this Possibilistic approach, we identified all potential ecosystem trajectories and provided their differential (non-systematic) impacts on heritage species richness (number). Hence, we rigorously demonstrate with this new type of model that grazing benefits marsh species which are faced with competition from common grassland species. The detailed analysis of the explicit state space and trajectories allows exploring simultaneously the identification of a range of recommendations for management strategies.

Modelling Approach

The paper illustrates analysis of the assumptions of the statistical component of a hybrid modelling approach for predicting environmental extremes. This shows how to assess the applicability of the approach to water quality problems. The analysis involves data on stream acidity from the Birkenes catchment in Norway. The modelling approach is hybrid in that it uses: (1) a deterministic or process-based description to simulate (non-stationary) long term trend values of environmental variables, and (2) probability distributions which are superimposed on the trend values to characterise the frequency of shorter term concentrations. This permits assessment of management strategies and of sensitivity to climate variables by adjusting the values of major forcing variables in the trend model. Knowledge of the variability about the trend is provided by: (a) identification of an appropriate parametric form of the probability density function (pdf) of the environmental attribute (e.g. stream acidity variables) whose extremes are of interest, and (b) estimation of pdf parameters using the output of the trend model.

Abstract Intractable long-term or chronic refugee communities present serious challenges to common refugee-management strategies. We argue that they are best understood and managed by using adaptive techniques drawn from complexity theory. To illustrate this strategy, we use the refugee communities situated along the Thai–Myanmar border as a case study. The article outlines the key elements of complexity theory, the complexity lens, for use in analysis of the problem. It then applies the complexity lens to the case study: identifying and describing the actors and networks that compose the complex system of the Thai–My refugees (the complex system) and the dynamic developments within that community over time (dynamic development). Based on this analysis, the article utilizes the complexity lens to evaluate the policy options commonly offered for the management of this ongoing refugee situation.

The Pearl River

The river chief system (RCS) has been innovatively implemented in Wuxi, China since 2007 for the eutrophication control of Tai Lake. In 2016, RCS was eventually promoted throughout China to reinforce river and lake protection. The success of this new river management system is generally attributed to collaboration, accountability, and differentiation effects. This research takes Foshan in the Pearl River Delta region as a case study to examine the feasibility and weaknesses in the implementation of the RCS. Prior to the formal adoption of RCS, a coordinating organization for river improvement undertaking was established in Foshan to overcome fragmentation in water management. Compared with this practice, the new RCS can strengthen the collaboration of administrative authorities and establish a considerably sophisticated and effective management structure. Emphasis on evaluation and accountability mechanisms guarantees that management goals can be achieved. However, similar to the previous one, the new system remains a temporary management practice and its outcomes depend partially on the commitment and capability of each river chief. The imperfect evaluation and accountability mechanism also weaken its long-term effectiveness in improving river water quality. Therefore, some corresponding policy instruments are needed to ensure that RCS can be implemented smoothly.

AbstractThe rate at which the poaching of rhinoceroses has escalated since 2010 poses a threat to the long-term persistence of extant rhinoceros populations. The policy response has primarily called for increased investment in military-style enforcement strategies largely based upon simple economic models of rational crime. However, effective solutions will probably require a context-specific, stakeholder-driven mix of top-down and bottom-up mechanisms grounded in theory that represents human behaviour more realistically. Using a problem-oriented approach we illustrate in theory and practice how community-based strategies that explicitly incorporate local values and institutions are a foundation for combating rhinoceros poaching effectively in specific contexts. A case study from Namibia demonstrates how coupling a locally devised rhinoceros monitoring regime with joint-venture tourism partnerships as a legitimate land use can reconcile individual values represented within a diverse stakeholder group and manifests as both formal and informal community enforcement. We suggest a social learning approach as a means by which international, national and regional governance can recognize and promote solutions that may help empower local communities to implement rhinoceros management strategies that align individual values with the long-term health of rhinoceros populations.

Grazing Strategies

There is an increasing interest in the development of livestock grazing management strategies that achieve environmental sustainability and maintain or improve the long-term production capacity of commercial grazing systems. In temperate Australia, these strategies are generally focussed on reducing perennial pasture decline, soil loss, acidity, and salinity. An additional challenge facing land managers and researchers is developing grazing strategies that also maintain and enhance local and regional biodiversity. However, few studies have assessed the compatibility of management practices for maintaining long-term productivity and biodiversity conservation. We still have only a very basic understanding of the effects of different grazing strategies and pasture management on biodiversity and this is a major impediment to the development of appropriate and compatible best management practice. We argue that although there is an increasing desire to find management strategies that protect and enhance biodiversity without hindering long-term agricultural production, in many cases this may not be possible. Current knowledge suggests that compatibility is most likely to be achieved using low-input systems in low productivity (fragile) landscapes, whereas in highly productive (robust) landscapes there is less opportunity for integration of productive land-use and biodiversity conservation. There is an urgent need for improved communication and collaboration between agronomic and ecological researchers and research agencies to ensure that future programs consider sustainability in terms of biodiversity as well as pasture and livestock productivity and soil and water health.

The purpose of this paper is to ascertain the effectiveness of the management strategies of the traditional Japanese confectioner Toraya. Rapid technological development and the demands of knowledgeable customers have made growth more difficult for manufacturers. We assume that the practices of longestablished manufacturers are best for others to follow. Toraya has been a high-value-added confectioner for almost 500 years. The reasons for its sustained competitiveness are described in this paper. We use the 3Cs analysis to clarify the business circumstances of the Japanese confection industry, the 4Ps analysis to explore Toraya’s structure, the strategic experimental module analysis to show the reliable value that Toraya offers its customers, and the Value, Rarity, Inimitability, and Organization analysis to explain its long-term success. The results reveal that Toraya has employed a low-technology strategy utilizing artisanal skill instead of machines and provides an excellent consumer experience that attracts customers. This is a sustainable competitive advantage because it takes years to establish and is not easily imitated. However, Toraya’s simple and effective management practices could be adopted as industry best practices.

Rusle Model

Simulation of soil erosion is an important phenomenon in watershed management studies because of the dynamic nature of soil. The present study demonstrates the capabilities of remote sensing coupled with GIS to extract soil erosion vulnerabilities using RUSLE model. Therefore this study understands spatial distribution of soil erosion at a macro-watershed scale. The input parameters for RUSLE model include the rainfall and erosivity (R) derived using the TRMM satellite precipitation product for a long term implementing regression model. The soil erodibility (K) factor is estimated using available soil map, and the topographic factor (LS) from 12m ALOS PALSAR DEM. The management practice information was extracted from the land use / cover map based on 30m multi spectral LANDSAT-8 of three season datasets. The RUSLE model predicted very low, low, moderate, high and very high erosion in 84.8%, 7.9%, 4.4%, 2.3% and 0.7% of reviewed area, respectively. The results were validated with ground infromation and NDVI, being the main identifiers of soil erosion. As presence of high vegetation indicates higher strength to hold the soil particles together and prevent soil erosion, correlation coefficient was generated to find accuracy of the results with NDVI of the area. The strong positive correlation (0.5) provided scientific support that prediction of soil erosion by RUSLE can be effectively used for watershed management and combating action plan for soil erosion.

And Performance

The long term management of a production asset raises several major issues, among which rank the technical management of the plant, its economics, and the fleet level perspective one has to adopt. Decision makers are therefore faced with the need to define long term policies (up to the end of asset operation) that take into account multiple criteria including safety (which is paramount) and performance. In this paper we first remind the reader of the EDF three-level methodology for asset management. As introduced in PVP 2003 and PVP 2004, this methodology addresses the component/technical level (how to safely operate daily and invest for the future), the plant level (how to translate technical decisions into plant-wide consequences including economic performance), and the fleet level (how to manage a large number of similar assets). We then focus on the software tool that implements this methodology in order to allow decision makers to define, evaluate, and analyze long term plant operation and maintenance policies. Lastly we show how the methodology and the software tool were used on a pilot case study. The technical and economic results obtained at the plant level are described as well as the conclusions one can draw from them in order to help decision makers evaluate and analyze long term asset management strategies.

Innovation Approach

We note the emergence of a new type of intermediary organization, which functions at system or network level, in contrast to traditional intermediary organizations that operate mainly bilaterally. These "systemic intermediaries" are important in long-term and complex changes, such as "transitions" to sustainable development, which require the coordinated effort of industry, policy makers, research institutes and others. We use the Systems of Innovation approach to characterize the roles of traditional and systemic intermediary organizations. A review of recent changes in innovation systems points to the need of more systemic efforts, such as the articulation of needs and options, the alignment of relevant actors and the support of learning processes. In a phase model of transitions additional roles of systemic intermediaries are identified. A case study of the Californian Fuel Cell Partnership shows how the efforts of systemic intermediaries in encompassing systemic innovations are useful and necessary, but not sufficient.
