After the development of a flood action plan (FAP) in 1988, the Bangladesh government has led practical actions for nationwide flood management. However, Bangladesh is on its way to improve the capacity and knowledge of sustainable infrastructure and non-structural countermeasures. Local government and communities are also struggling to mitigate flood risk and severe damage. Therefore, a government-driven strategy of capacity building on sustainable flood risk management is an inevitable process to support local authorities' responsibility under the leadership. This pilot study introduced the GIS-based integrated flood management (GiFM) for improving nationwide flood risk management at different levels from communities. First, we proposed the conceptual framework of GiFM to strengthen local government-based capacity focusing on a cost-effective way under the FAP. Then the proposed GiFM employed hydro-GIS geo-database and Earth Observation (EO) data for sharing information on the current flood risk situation including flood monitoring, forecasting and river embankment erosion in transboundary river basins. For flood risk reduction, the prototype of GiFM showed a good example of consultation and action plan to realize high-priority demands at all levels of multi-stakeholders, from decision makers to residents who are living in vulnerable low-lying floodplains of Bangladesh.

International studies point out that some freshwater policy objectives are not achieved. This study describes that this is in part caused by shortcomings that include: the lack of targeted monitoring schemes to measure impact; a too small range of specific technologies rather than a wider suite of integrated multiple technologies; a too tight focus on sub-sets of stakeholders instead of the involvement of the wider range of end users; and poor trust building and technology explanations to end users. As an example, the New Zealand government is addressing widespread concern over the deterioration of the national freshwater resource by supporting a diverse portfolio of land and riparian management actions. Efforts to assess the effectiveness of these interventions and establish an evidence-based framework for future policies are however limited by the existing regional-scale freshwater monitoring infrastructure. Such hydrometric networks were established largely to assess the broader-scale regional 'state' of the environment and are generally out-of-phase with freshwater improvement actions that are implemented more typically at edge-of-field, farm or sub-catchment scales. Recent and rapid evolution in sensor technologies have created new opportunities to deliver information tuned to the appropriate parameters and frequencies needed to evaluate improvement actions. Despite this, the necessary transformative change in freshwater monitoring has yet to gather pace. In this study we explore barriers and solutions with the objective to better understand what is needed for successful integration of innovative monitoring technologies in a transitional environmental policy setting, using recent New Zealand policy directives as a case study. We use expert surveys and scenario testing to explore barriers to adoption to more robust and comprehensive monitoring required to establish the success, or otherwise, of freshwater improvement actions. This process reveals that rather than further innovations in technology, change in ...
