This paper discusses the benefits of applying Systems Thinking to solving natural resource management problems. It first explains the Systems Thinking concept and briefly outlines its history and emergence in agriculture and natural resource management. A series of case studies are then presented which illustrate practical examples of how Systems Thinking has been used to address real life natural resource management issues. The case studies build on the conclusions of each other by adding additional ways (lessons learnt) of incorporating Systems Thinking into practice to address issues more systemically. The first case study deals with examples of how Systems Thinking facilitated the sharing and integration of disparate sources and forms of knowledge, and making sense of the factors influencing tree density in the tropical savanna region of northern Queensland. The second case study deals with how Systems Thinking has been imbedded in the design and implementation of a research project investigating how to improve financial returns to smallholder tree farmers in the Philippines. The third case study illustrates how Systems Thinking was used to design and facilitate an adaptive rodent management project in Cambodia based on participatory research, development and extension. From these experiences, the authors' highlight a variety of key points that lead to the proposition that Systems Thinking should be ‘absorbed’ into scientific research, in the same way that statistics, is today an integral part of all sciences. A framework for the application of Systems Thinking is presented to help improve sustainable land management. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Making playspaces inclusive has predominately focused on internal design, addressing factors that constrain play experiences within these spaces for children with diverse impairments and their families. Less attention, however, has been paid to the journey to the site and how that may influence the decision to visit these environments. This paper contributes to this area by discussing the experiences of 10 children with diverse mobility impairments, aged 9–12-years-old, and their families from south-east Queensland, Australia. This person–environment study of their journeys to playgrounds illuminates the role getting to the site and entering the site plays in shaping decisions to actually visit playspaces. The findings also identify key considerations applicable to open space planning and site planning, towards achieving inclusive landscapes for play. [ABSTRACT FROM AUTHOR]

In rural regions, land use changes (LUC) are often the result of the decision-making of individual farmers. To influence this decision-making, compulsory and voluntary mechanisms are implemented. However, farmers’ decision-making is a heterogeneous process that depends on their ability and willingness to take certain decisions. Discrepancies between farmers’ ability and willingness and the design of voluntary mechanisms occur frequently. This makes it necessary to understand how farmers’ participation in these mechanisms can affect LUC. The aim of this paper was to demonstrate an agent-based approach to analyse and explore how voluntary mechanisms can influence LUC processes in rural regions. This approach was applied to a rural region in Australia, where clearing of native vegetation has occurred for agricultural development. Historical land cover data and semi-structured interviews were used to parameterise an agent-based model. Factors that influence farmers’ ability and willingness to participate in these mechanisms were identified. Three scenarios were simulated with the model to explore how the implementation of different voluntary mechanisms can affect the landscape structure of the region. This paper identifies how the diversity of farmers’ decision-making can influence the landscape structure in the region. The advantages and limitations of an agent-based approach in relation to LUC research and policy are discussed. [Copyright &y& Elsevier]

Payments for Ecosystem Services (PES) are seen by many as one of the defining projects of a more neoliberalised approach to environmental governance. In practice, however, many PES schemes are hybrid constructions, depending on a mix of market and non-market policy instruments and the involvement of state as well as non-state actors to achieve changes in environmental practice on the ground. In this paper we provide insights into how and why hybrid forms of governance enable PES schemes to be workable in practice, and the implications of these arrangements for the neoliberalisation of rural environments and subjects. Focussing on the hybrid governance strategies of institutional blending and contextual adaptation, we examine two PES schemes in the State of Queensland, Australia. Conserving native vegetation and protecting the Great Barrier Reef respectively, these programmes have used PES as part of a suite of initiatives to achieve improvements in the environmental practices of beef producers. Our analysis reveals that institutional blending and contextual adaptation were crucial in building trust between landholders, farming organisations and those agencies responsible for delivering schemes; enabling the alignment of PES with existing mechanisms of governing, such as regulation and extension; meeting the outcomes required by government funding agencies, often in a short timeframe; improving the targeting of specific land types or landholders; improving the quantity and quality of funding applications; and overcoming fears about perceived threats to private property rights. While these strategies were important in making each PES scheme workable, the use of non-market instruments of regulation and extension compromised the application of neoliberal policy prescriptions to rural environments . However, we argue also that these same instruments contributed to and reinforced the construction of neoliberal landholder subjectivities . [ABSTRACT FROM AUTHOR]

Abstract: The use of landholder typologies to assist in the development of natural resource management (NRM) policies and agricultural extension programs has increased considerably in the past decade. In this paper we explore the potential of developing a typology of graziers to more effectively tailor policies and programs with the aim of improving land management outcomes. This is of particular importance since growing public concern about the environmental performance of the beef industry has led to increasing pressures on graziers to change their land management practices to decrease off-property impacts. To gain a better understanding of graziers’ land management practices and the factors that inform their decisions on how they manage their land we first developed a conceptual model of the relationship between grazier and grazing land where both can, ideally, thrive through conscious and timely land management decisions made and implemented by the grazier. A successful grazier land relationship is likely to be consistent with value systems and social and economic factors, although the particulars of any individual approach may vary spatially and temporally. These factors, in particular graziers’ values and motivations to follow a particular management strategy, guided the development of our typology of graziers. Australia''s Bowen-Broken basin, which has been identified as a major contributor of sediment and nutrients that enter the Great Barrier Reef lagoon, served as a case study for this research. Three broad types of graziers emerged: (1) traditionalists, (2) diversifiers, and (3) innovators. The authors argue that by understanding graziers’ values and motivations underlying each of the grazier types, government agencies and NRM organisations can more effectively tailor their policy and extension programs towards specific types of graziers and can work with specific groups to achieve reductions in sediment and nutrient runoff from grazing properties.

Summary: In many agricultural regions investments are made into improved land management and catchment restoration with the aim of reducing sediment and nutrient delivery to downstream water bodies. This paper presents the results of an 8year field study that evaluated the impact of improved grazing land management (GLM) on a 14km2 sub-catchment of the Burdekin River in northern Australia. Land condition recovery and changes to runoff and sediment yield were measured on hillslopes (using three flumes) and at the end of the catchment (using automatic water sampling). Ground cover was monitored at the beginning of the wet season at hillslope and catchment scales using direct measurement and Quickbird satellite imagery. At the catchment scale, improved GLM resulted in an increase in mean ground cover between 2003 and 2007, relative to a control grazing property. However, the total suspended sediment yield from hillslopes did not decline due to the disproportionately high yields from low (<10%) cover sites particularly in high runoff years. In 2007, when there was above-average rainfall, 97% of the hillslope derived fine sediment was coming from less than 3% of the catchment. Catchment sediment yield also increased, associated with higher rainfall and runoff in latter years of the study. In years of above-average rainfall, it is estimated that less than 40% of catchment sediment yield was derived from hillslope erosion. Channel erosion is considered to contribute the remaining sediment. Rehabilitation of hillslope scalds and gullies is likely to be an important companion to improved GLM to reduce catchment fine sediment yields in this landscape. Evaluation of gully and hillslope scald rehabilitation techniques is required, including the economic feasibility of such options. [Copyright &y& Elsevier]

Summary: Poor land condition resulting from unsustainable grazing practices can reduce enterprise profitability and increase water, sediment and associated nutrient runoff from properties and catchments. This paper presents the results of a 6year field study that used a series of hillslope flume experiments to evaluate the impact of improved grazing land management (GLM) on hillslope runoff and sediment yields. The study was carried out on a commercial grazing property in a catchment draining to the Burdekin River in northern Australia. During this study average ground cover on hillslopes increased from ∼35% to ∼75%, although average biomass and litter levels are still relatively low for this landscape type (∼60 increasing to 1100kg of dry matter per hectare). Pasture recovery was greatest on the upper and middle parts of hillslopes. Areas that did not respond to the improved grazing management had <10% cover and were on the lower slopes associated with the location of sodic soil and the initiation of gullies. Comparison of ground cover changes and soil conditions with adjacent properties suggest that grazing management, and not just improved rainfall conditions, were responsible for the improvements in ground cover in this study. The ground cover improvements resulted in progressively lower runoff coefficients for the first event in each wet season, however, runoff coefficients were not reduced at the annual time scale. The hillslope annual sediment yields declined by ∼70% on two out of three hillslopes, although where bare patches (with <10% cover) were connected to gullies and streams, annual sediment yields increased in response to higher rainfall in latter years of the study. It appears that bare patches are the primary source areas for both runoff and erosion on these hillslopes. Achieving further reductions in runoff and erosion in these landscapes may require management practices that improve ground cover and biomass in bare areas, particularly when they are located adjacent to concentrated drainage lines.

To protect and improve water quality in the Great Barrier Reef, the Queensland Government's Reef 2050 Water Quality Improvement Plan targets that 90% of sugarcane, horticulture, cropping and grazing lands in priority areas be managed using best management practices for sediment, nutrient and pesticides by 2025. Progress towards this target is insufficient and variable across catchments and industries. The motivation to adopt improvements in management practices is heavily influenced by social, economic, cultural and institutional dimensions. In this paper we synthesise the literature on how these human dimensions influence decision making for land management practice and highlight where future investment could be focussed. We highlight that focussing on —1) investigating systems to support landholder decision making under climate uncertainty (risk); 2) generating a better understanding of the extent and drivers of landholder transaction cost; 3) understanding if there are competing 'right' ways to farm; and 4) improving understanding of the social processes, trust and power dynamics within GBR industries and what these means for practice change— could improve practice change uptake in the future. • Understanding human factors is essential for land practice change • Human factors include economic, social and cultural and macro institutional elements • These will affect trialling, adoption and dis-adoption of a practice [ABSTRACT FROM AUTHOR]

Understanding how private landholders make deforestation decisions is of paramount importance for conservation. Behavioural frameworks from the social sciences have a lot to offer researchers and practitioners, yet these insights remain underutilised in describing what drives landholders' deforestation intentions under important political, social, and management contexts. Using survey data of private landholders in Queensland, Australia, we compare the ability of two popular behavioural models to predict future deforestation intentions, and propose a more integrated behavioural model of deforestation intentions. We found that the integrated model outperformed other models, revealing the importance of threat perceptions, attitudes, and social norms for predicting landholders' deforestation intentions. Social capital, policy uncertainty, and years of experience are important contextual moderators of these psychological factors. We conclude with recommendations for promoting behaviour change in this deforestation hotspot and highlight how others can adopt similar approaches to illuminate more proximate drivers of environmental behaviours in other contexts.

Australian and Queensland Government's Reef 2050 Water Quality Improvement Plan has set targets for improving the water quality entering the Great Barrier Reef lagoon. Given the large public investment and the deficit of data linking on-farm land management to changes in environmental outcomes, there is a need for a robust and efficient methods of quantifying links between land management and water quality. This paper explores a pragmatic approach to making this link using available data. We demonstrate that a simple parameterisation process is suitable for estimating hydrology and water quality across a wide range of land uses and management practices in agricultural landscapes. However, a manually calibrated model may still require the analysis of parameters to reduce error variances and evaluate uncertainties. Confidence in estimating hydrology and water quality in descending order is: runoff, sediment, nitrogen, phosphorous, and pesticide losses, reflecting the availability of data and inherent error propagation. • A pragmatic modelling by Howleaky is suitable to link management to water quality. • A manually calibrated model may still require a reduction in error variances. • Data availability and inherent error propagation determined confidence in modelling.

Context: Fauna distributions are assessed using discrete (binary and mosaic) or continuous conceptualisations of the landscape. The value of the information derived from these analyses depends on the relevance of the landscape representation (or model) used to the landscape and fauna of interest. Discrete representations dominate analyses of landscape context in disturbed and regenerating landscapes; however within-patch variation suggests that continuous representations may help explain the distribution of fauna in such landscapes. Objectives: We tested the relevance of binary, mosaic, and continuous conceptualisations of landscape context to reptiles in regenerating dryland landscapes. Methods: For each of thirteen reptile groups, we compared the fit of models consisting of one landscape composition and one landscape heterogeneity variable for each of six landscape representations (2× binary, 2× mosaic, and 2× continuous), at three buffer distances. We used Akaike weights to assess the relative support for each model. Maps were created from Landsat satellite images. Results: Reptiles varied in their response to landscape context; however, the binary landscape representation with classes 'intact/disturbed' was best supported overall. Species richness was best described by a binary landscape representation with classes 'wooded/clear', whereas reptile abundance was best described by a mosaic landscape representation with classes defined by vegetation type. Five out of ten reptile species responded strongly to a single landscape representation, with the most relevant representation and conceptualisation varying among species. Conclusions: Our findings support the use of multiple landscape conceptualisations and representations during analyses of landscape context for fauna in regenerating landscapes.

Aim To develop and test a general framework for estimating weed invasion potential (suitability and susceptibility) that utilized expert knowledge of dispersal, establishment and persistence and considered the influence of land management. Location The semi-arid Desert Channels Region of Queensland, Australia (476,000 km2). Methods We developed a general framework that integrated knowledge and empirical data of the environmental and land management variables influencing the dispersal, establishment and persistence of the invasive shrub parkinsonia ( Parkinsonia aculeata) using a Bayesian network linked to a Geographic Information System (GIS). We evaluated the influence of different land management scenarios on landscape suitability for parkinsonia. Model performance was assessed by comparing predicted landscape suitability with mapped parkinsonia locations and estimated parkinsonia density. Results Our predictions of moderate to high suitability corresponded reasonably well with mapped parkinsonia locations (71% match) and areas of common to abundant estimated density (92% match). They also suggested that parkinsonia has not reached its potential distribution within the study region. Under current land management conditions, 77,000 km2 of land was found to be highly or moderately suitable for parkinsonia. Scenario analysis indicated that maintaining moderate herbaceous ground cover levels, and using sheep to browse juvenile parkinsonia, reduced the predicted moderate to high suitability area to 27,000 km2, offering a potential management strategy for limiting parkinsonia invasion. Main conclusions Weed invasion potential can be reasonably estimated using expert knowledge of dispersal, establishment and persistence, integrated using a Bayesian network linked to a GIS. This modelling approach can be an alternative to process-based and phenomenological modelling, which can be problematic for modelling new and emerging weed invasions, particularly where data are patchy. The modelling approach also allows the influence of land management change on invasion potential to be investigated through scenario analysis. [ABSTRACT FROM AUTHOR]

Recent decades have witnessed increasing attention in theory and practice to participatory approaches to policy appraisal, in part due to the potential of such approaches to facilitate reflexive policy appraisal. It has been observed, however, that in practice these approaches are often as prone as traditional, non-participatory appraisal techniques to being limited in the extent to which that can achieve reflexivity e.g. due to the influence of interests and power and problems of representation. This article explores the extent to which Q Methodology, or ‘Q’, can play a role in ‘opening up’ (Stirling Science, Technology & Human Values, 33, 262–294, 2008) policy to reflexive appraisal. A Q study of fire management discourses in Cape York, northern Australia is presented which exposes the existence of four key discourses in the region: discourse A—rational fire management; discourse B—fire-free conservation; discourse C—pragmatic, locally controlled burning; and discourse D—indigenous controlled land management. At present only discourses A and C are reflected in policy. Appraising existing policy on the basis of the different constructions articulated by discourses B and D of the purpose of and practices involved in fire management, is successful in opening up existing policy to reflexive appraisal. In the face of considerable scientific uncertainty as to the ecological impacts of different burning regimes in northern Australia, this process of opening up has important potential for appraising the social desirability of existing policy and practice in the region. This analysis provides a practical demonstration of the wider potential of Q Methodology in opening up other important contemporary policy issues to reflexive appraisal. It also provides the basis for recommending the expansion of participatory processes for facilitating stakeholder engagement in fire management policy and practice in Cape York.

Forty-four study sites were established in remnant woodland in the Burdekin River catchment in tropical north-east Queensland, Australia, to assess recent (decadal) vegetation change. The aim of this study was further to evaluate whether wide-scale vegetation ‘thickening’ (proliferation of woody plants in formerly more open woodlands) had occurred during the last century, coinciding with significant changes in land management. Soil samples from several depth intervals were size separated into different soil organic carbon (SOC) fractions, which differed from one another by chemical composition and turnover times. Tropical (C4) grasses dominate in the Burdekin catchment, and thus δ13C analyses of SOC fractions with different turnover times can be used to assess whether the relative proportion of trees (C3) and grasses (C4) had changed over time. However, a method was required to permit standardized assessment of the δ13C data for the individual sites within the 13 Mha catchment, which varied in soil and vegetation characteristics. Thus, an index was developed using data from three detailed study sites and global literature to standardize individual isotopic data from different soil depths and SOC fractions to reflect only the changed proportion of trees (C3) to grasses (C4) over decadal timescales. When applied to the 44 individual sites distributed throughout the Burdekin catchment, 64% of the sites were shown to have experienced decadal vegetation thickening, while 29% had remained stable and the remaining 7% had thinned. Thus, the development of this index enabled regional scale assessment and comparison of decadal vegetation patterns without having to rely on prior knowledge of vegetation changes or aerial photography.

In the Australian Wet Tropics World Heritage Area (WTWHA), protected areas impact on the rights and obligations of Indigenous traditional owners. This research investigated the effectiveness of two new policy instruments, a negotiated agreement, and a protocol, as mechanisms to bridge between the differing protected area management approaches of Kuku-Yalanji Aboriginal people and the WTWHA managers. The policy innovation sought from these instruments reflects a paradigm shift in protected areas globally toward a more inclusive approach, and recognition of diversity in governance types. However, the instruments' effectiveness in achieving innovation was hampered by the lack of substantive legal mechanisms to overcome the colonial legacy within protected areas. Legislative reform to properly recognize diversity in protected area governance would assist effective bridging. Internationally, rigorous criteria to measure progress toward a more inclusive approach in national systems would enhance our capacity to ensure the current paradigm shift becomes more than convenient rhetoric.
