Participatory modeling is increasingly recognized as an effective way to assist collective decision-making processes in the domain of natural resource management. This article introduces a framework for evaluating projects that have adopted a participatory modeling approach. This evaluation framework--known as the "Protocol of Canberra"--was developed through a collaboration between French and Australian researchers engaged in participatory modeling and evaluation research. The framework seeks to assess the extent to which different participatory modeling initiatives not only modify perceptions among and interactions between participants, but also contribute to collective decision-making. The article discusses the development of the framework and its application to three case-studies, two from Australia and one from the Pacific Island of the Republic of Kiribati. The article concludes with some comments for future use of the framework in a range of participatory modeling contexts.

Population centers in low, small islands have water supply problems that are among the most critical in the world. Limited land areas and extremely large soil hydraulic conductivities severely reduce surface runoff and surface storage, so that thin lenses of fresh groundwater floating over seawater comprise the major source of fresh water for people in many atolls. Atoll groundwater is extremely vulnerable to frequent El Niño Southern Oscillation (ENSO)–related droughts, salinization due to storm surges and sea‐level rise, and to human activities with vadose zone transit times from surface to shallow groundwater being less than 1 h. We examine the relationship between groundwater, rainfall, and ENSO events in a low atoll, Tarawa, in the central and western Pacific Republic of Kiribati. Droughts can last as long as 43 months and occur with a current frequency of 6 to 7 years. The impact of droughts on the quality and quantity of a fresh groundwater lens is explored. The local drawdown of the water table due to pumping from long horizontal infiltration galleries is found to be less than diurnal tidal variations. The saturated hydraulic conductivity, K0, of the Holocene unconsolidated coral sands was estimated from infiltration gallery drawdown in two islands. The geometric mean K0 was 14.6 m d−1 with a range from 0.9 to 111 m d−1 These large K0 values cause the rapid transmission of rainfall and surface pollutants through the unsaturated zone to groundwater. An example is given of Escherichia coli pollution due to traditional activities. Strategies for improving the adaptation of island communities and increasing resilience to climate change are discussed.

Population centres in low atoll islands have water supply problems that are amongst the most critical in the world. Fresh groundwater, the major source of water in many atolls, is extremely vulnerable to natural processes and human activities. Storm surges and over-extractions cause seawater intrusion, while human settlements and agriculture can pollute shallow groundwaters. Limited land areas restrict freshwater quantities, particularly in frequent ENSO-related droughts. Demand for freshwater is increasing and availability is extremely limited. At the core of many groundwater management problems are the traditional water ownership rights inherent in land tenure and the conflict between the requirements of urbanised societies and the traditional values and rights of subsistence communities living on groundwater reserves. Resource limitations and geographic isolation restrict the potential for increasing wealth through crop exports. Water governance reforms and the provision of knowledge to communities are critical. Regional water organisations, fostering self-support, are a key to developing island-adopted and owned solutions.

Forests across the world stand at a crossroads where climate and land-use changes are shaping their future. Despite demonstrations of political will and global efforts, forest loss, fragmentation, and degradation continue unabated. No clear evidence exists to suggest that these initiatives are working. A key reason for this apparent ineffectiveness could lie in the failure to recognize the agency of all stakeholders involved. Landscapes do not happen. We shape them. Forest transitions are social and behavioral before they are ecological. Decision makers need to integrate better representations of people's agency in their mental models. A possible pathway to overcome this barrier involves eliciting mental models behind policy decisions to allow better representation of human agency, changing perspectives to better understand divergent points of view, and refining strategies through explicit theories of change. Games can help decision makers in all of these tasks. scales: decades to centuries for changes in temperature and rainfall patterns against years and sometimes months for agriculture conversion, infrastructure development, logging operations, and political regime shifts. 5 Agriculture is the main driver of deforestation. 6,7 Net deforestation in the tropics dominates 8 with various regional drivers: 9 ranching and soybean expansion ll

We use games in the classroom to allow students to embrace the complexities of ecosystem management, and to foster adaptation and creativity. The experience of gaming will ensure the lessons drawn during the game and the after-action discussions will not be easily forgotten. With a skilled team of facilitators, few other approaches to teaching can match the immersive qualities of gaming.

A majority of Madagascar's rural people depend on the primary sector. The country's agricultural hub, the Alaotra-Mangoro region, is mainly tied to fisheries and rice production. Increasing human population and decreasing output from fisheries and agriculture are pushing the rural resource users further into the protected marshlands. Understanding rural farmers' decisions can help developing improved management plans to support long-term functioning of (socio-) ecological systems. We present here an example of inter-and transdisciplinary research which uses a participatory modelling approach to develop a shared vision of the Alaotra socio-ecological system. The purpose of this study is to introduce the used gaming approach in detail by documenting the process of co-construction of the Alaotra wetlands' conceptual model. We then describe how the model is transcribed into a table-top role-playing game that will help researchers and stakeholders alike explore and understand decisions and management strategies. We finally report on first outcomes of the game including land use decisions, reaction to market fluctuation and landscape change.

Low coral islands are heavily dependent on groundwater for freshwater supplies. The declaration by the government of Kiribati of water reserves over privately owned land has led to conflicts, illegal settlements, and vandalism. Also, the water consumption tends to increase toward Western-like standards, and human pollution has already contaminated most freshwater lenses. This project aims to provide relevant information to local stakeholders to facilitate dialogue and devise sustainable water management practices. A computer-assisted role-playing game is implemented to fulfill this aim. The following three-stage methodology is applied: collecting local and expert knowledge, blending the di ferent viewpoints into a game-based model, and playing the game with the di ferent stakeholders to explore di ferent scenarios. Although game sessions delivered successful outcomes, the final stage of the project is characterized by the upheaval of contradictory government stands that undermine the whole process. It is argued that heterogeneous viewpoints may be handled in a satisfactory manner during the gaming sessions but that long-term hidden agendas may override the outcomes. Beyond the inherent question of legitimacy attached to such approaches, some players clearly must deal with constraints that are often genuinely considered external to the ongoing negotiation process.

Background and Aim. It is often assumed in natural resources management that communication helps with solving the 'tragedy of the commons' by way of shared knowledge and better coordination. ReHab is a role-playing game, both cooperative and competitive, exploring the role of knowledge production and communication for the conservation and management of natural resources through experiential learning.
