- In Cochabamba, the vulnerability assessment process focused on La Maica community and the agriculture sector. Community stakeholders were involved in workshops while municipal and regional actors participated through interviews. In the Kota process, the municipality was in the geographical focal point and a multi-level stakeholder group focused upon slum inhabitants. The suggested interventions and actions in both cities were dominated by systems (infrastructure and ecosystems) while identified barriers and facilitating factors to implementation revealed a greater acknowledgement of governance issues. Focus on marginalized groups and sectors is facilitated by the direct representations of those issues. While multi-stakeholder processes can be important forums for social learning adaptation planning that benefit vulnerable sectors and groups, with limited inclusion and responsibility given to representatives of marginalized sectors and groups for implementation actions, it is likely that the interests and priorities of more powerful actors will dominate and not contribute to increasing the resilience of the most vulnerable. © 2018 The Author(s).

- A rainfall-runoff model has been established to simulate streamflow in a regulated catchment in southern India, where data were limited in relation to the basin's complexity. Within the basin is a network of hydropower reservoirs and tunnels that complicate the relationships between observed and natural flows. The basin is affected by two monsoons that dominate in different areas and can only be quantified through a relatively sparse raingauge network. These characteristics combine to make it difficult to satisfactorily define the spatial distribution of rainfall inputs to the basin. After critically assessing the data that were found to be inconsistent and unrepresentative, various assumptions about the operation of the system were tested. Despite incomplete streamflow data and the complex hydropower system, the limiting factor affecting successful simulations of streamflow at the basin outlet was the uncertain representativeness of the calculated areal rainfall. The final outcome is a model, which despite shortcomings, is considered to be a useful water resources management tool that provides a sound basis for further studies.

Simulating the impacts of land-use and climate change on water resource availability for a large south Indian catchment

- A monthly rainfall-runoff model was calibrated for a large tropical catchment in southern India. Various land-use and climatic change scenarios were tested to assess their effects on mean annual runoff and assured water yield at the Bhavanisagar Reservoir in Tamil Nadu, India. The largest increase in runoff (19%) came from converting forest and savanna (the indigenous control scenario) to agriculture. Mean annual runoff decreased by 35% after conversion to commercial forest and 6% after partial conversion to tea plantations. The predicted climate scenarios of reduced dry season rainfall decreased the annual runoff by 5% while enhanced annual rainfall caused a 17% increase in runoff. Even if land-use and climate changes had relatively large effects on runoff, the changes in reservoir yield which can be assured every year, were often less severe. This was probably due to the buffering effect of the reservoir and variation in the mean annual runoff.
