Lenses for learning: Visual techniques in natural resource management

In this study, we explored the use of selected visual techniques (e.g. video, photography, diagramming) infacilitating learning among Indigenous communities living in remote protected areas at sites in Vietnam and Australia. The techniques were employed during interviews and workshops aimed at accessing and enhancing local peoples’ perspectives on their landscape and on specific natural resource management issues. The effectiveness of the different techniques for enabling learning varied markedly with the context, highlighting the need for facilitator skill and flexibility in application of techniques. Visual techniques helped to engage participants; encourage unrestrained and lateral thinking; provide opportunities for self-expression and reflection; and to expose participants to perspectives of other community members. Valuable insights emerged on broad aspects of learning and these were incorporatedinto a simple model that highlights three types of conceptualisation found to be important in these processes

Listening to locals on payments for environmental services

Payments for Environmental Services (PES) is gaining recognition worldwide as a serious option for conservation of ecosystems, as well as potentially improving the livelihoods of people providing environmental services. However, little attention has been paid to research on views of local people in their potential roles as service providers. In this research we explore perspectives of poor people living in a National Park in Vietnam, where introduction of PES is being considered. In-depth interviews and workshops were conducted – with strong emphasis on the use of visual techniques, to help facilitate learning processes and provide insight into local perspectives. From the research, two models were developed to indicate general factors that influence the likelihood of people adopting, and adhering to, PES schemes. We suggest these models can be used to guide the design of PES. Our findings also reveal three main requirements important in design of pro-poor PES: (1) Thorough scoping studies for ensuring that schemes are based on sound understanding of potential providers' perspectives and context. (2) Such studies should emphasise qualitative research and draw on participatory tools, to facilitate open dialogue and co-learning by researchers and participants. (3) Policy makers should consider designing hybridized schemes, i.e., in which PES concepts are combined with integrated conservation and development

Understanding and managing groundwater and salinity\ud in a tropical conjunctive water use irrigation district

Agricultural production around the world is increasingly being constrained by hydrological factors—such as over-extraction of groundwater in some locations, rising water tables in others, and worsening groundwater quality in general. One such area is the Lower Burdekin irrigation area in northern tropical Australia, where rising watertable levels and increasing salinity concentrations within alluvial deposits are causing concern. The aim of this study was to improve understanding of the processes driving trends in groundwater quantity and quality in Mona Park, a conjunctive water use irrigation district in the Lower Burdekin. The analysis is intended to enable land and water managers to explore alternative policy and management practices to help support the reversal in current trends, and to improve water table conditions in terms of both water quantity and quality. Key lessons that are applicable\ud to the development of new irrigation schemes in wet–dry tropical regions elsewhere in the world are emphasised.\ud This study demonstrated that simple qualitative methods that link historical developments and observed climatic and hydrological trends can support development of a robust\ud understanding of groundwater behaviour. The results showed that to minimise groundwater accessions in wet–dry tropical regions, a large soil water deficit should be maintained\ud in the unsaturated zone prior to the onset of the wet season to buffer against potentially large wet season recharge events, and that this strategy should be implemented from when irrigation is first commenced. It is very clear that groundwater systems under or down gradient from irrigated areas need to be managed adaptively, such that: (1) timely decisions are made in response to changes in watertable level and groundwater quality; and (2)\ud suitable mechanisms are in place to ensure farmers have the financial incentives and flexibility to respond in the short-term. The work also demonstrated that the establishment of good baseline data prior to irrigation development, and long-term analysis (>30 years) involving various combinations of wet and dry periods, are required in order to build a comprehensive understanding of potential groundwater behaviour and adaptive management\ud needs
