| We used multi-agent systems (MAS), following the companion modeling method, to facilitate water management negotiations in Bhutan. We show how this methodology helped resolve a conflict over the sharing of water resources by establishing a concrete agreement and creating an institution for collective watershed management. The conceptual model begins with a role-playing game (RPG). The stakeholders play the game, thus validating the proposed environment, the behavioral rules, and the emergent properties of the game. It is then relatively easy to translate the RPG into computerized MAS that allow different scenarios to be explored. After this first step in the MAS model, stakeholders then create an institution. A second model is developed to facilitate this... |

| The management of urban water resources plays an important role for developing countries. The Tietê and Pinheiros Rivers (São Paulo, Brazil) are affected by domestic and industrial effluents and by the diffuse pollution. This research aimed to quantify 134 variables in the water of Tietê and Pinheiros Rivers (approximately 7,200 and 6,600 analyses, respectively) from August 2007 to December 2008. The idea was to verify if the fact that both rivers are located in the same basin is enough to consider the application of a single management plan for both. Data showed that the rivers presented significant anthropogenic interference. The results suggested that such rivers must be subjected to individual management plans since there were exclusive occurrences... |

| The Guapi-Macacu watershed is located in the Brazilian state of Rio de Janeiro, has a drainage area of about 1.640 km2, and drains into the Guanabara Bay northeast of the metropolitan area. The upper catchment in the Serra dos Órgãos mountain range is covered by dense old-growth forest of high biological diversity, while pastures and agricultural land dominate in the lower catchment. Apart from its outstanding biological value, the watershed provides crucial services including water supply to 2.5 million inhabitants in five municipalities. Nevertheless, forests and soils in the lower watershed are highly degraded due to the expansion of the agricultural frontier, overexploitation, and suburbanisation processes. Several pressures on this ecosystem persist.... |

| Abstract: We investigated the fluvial geochemistry of two catchments at different stages in the forest recovery process which have been a focus of an Environmental Services Payment (ESP) program in Brazil. The Posses (PS) and Salto de Cima (SC) catchments (1200 ha and 1500 ha, respectively) are situated in the municipality of Extrema, Minas Gerais state. Their streams flow into the Jaguari River that supplies part of the water demand of the São Paulo metropolitan area. Samples were collected for chemical analysis and physical-chemical field measures every 2 weeks from January to December 2017. An important pollution point source was discovered in the PS stream related to bovine urine and feces, as well another unidentified source that can be related to a... |

| Through rapid assessment of existing literature and review of policy and other official documents, the report synthesizes the existing knowledge and gaps on policies and institutions and identifies key research issues that need in-depth study. The report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin (BNB) and highlights their relative dependence on, and vulnerability to, water resources and water-related ecosystem services. It also makes an inventory of current water and land related policies and institutions in the BNB, their organizational arrangements, dynamics and linkages and key policy premises. It highlights the major problems in institutional arrangements and policy gaps and makes suggestions for... |

| Limited water resources are increasingly constrained by growing water demand for agricultural, industrial, and domestic uses, which in turn exacerbates environmental degradation and water-quality problems. This research report develops and applies a comprehensive decision-support tool for examining these issues at the river-basin level—the natural unit of analysis for water allocation and use. Authors Ximing Cai, Claudia Ringler, and Mark Rosegrant develop an integrated hydrologic– economic river-basin model, simulating water flows, salinity balances, and crop growth under water-allocation scenarios. One of the main advantages of the model is its ability to reflect the dynamic interactions of essential hydrologic, agronomic, and economic components and to... |
