Contiguous urban rivers should not be necessarily submitted to the same management plan: the case of Tietê and Pinheiros Rivers (São Paulo-Brazil) Anais da ABC (AABC)
Cunha,Davi G. F.; Grull,Doron; Damato,Murilo; Blum,José R. C.; Eiger,Sergio; Lutti,José E.I.; Mancuso,Pedro C. S..
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...

Mayordomía del agua : propuesta a partir del análisis de sus usos y riesgos en la cuenca "La Antigua", Veracruz. Colegio de Postgraduados
Román Jiménez, Ana Rita.
El manejo actual del agua en México contradice la postura oficial respectiva. Para mostrar algunos ejemplos, se analizaron los distintos usos del agua y el suelo en la cuenca La Antigua (2,326.43 Km2) en Veracruz, describiéndola como un estudio de caso. La precipitación anual estimada es abundante, su uso es continuo en las tierras de la región, y aún se considera que existen problemas de abastecimiento de agua. Los objetivos de este análisis fueron: Identificar la consistencia entre las formas actuales de uso del agua y algunas nociones básicas de lógica económica; examinar si existe escasez de agua con base en las expectativas de los usuarios; y mostrar que las inquietudes sobre los temas del agua se pueden enfrentar mejor al introducir el concepto de...

Companion Modeling, Conflict Resolution, and Institution Building: Sharing Irrigation Water in the Lingmuteychu Watershed, Bhutan Ecology and Society
Gurung, Tayan Raj; RNR Research Centre, Council for RNR Research of Bhutan, Ministry of Agriculture, Bhutan; tayangurung@yahoo.com; Bousquet, Francois; CIRAD Green TA 60/15 Campus de Baillarguet 34398 Montpellier Cedex 5 France; bousquet@cirad.fr.
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...

Network approaches for understanding rainwater management from a social-ecological systems perspective Ecology and Society
Prager, Steven D.; International Center for Tropical Agriculture (CIAT); s.prager@cgiar.org; Pfeifer, Catherine; International Livestock Research Institute (ILRI); c.pfeifer@cgiar.org.
The premise of this research is to better understand how approaches to implementing rainwater management practices can be informed by understanding how the people living and working in agroecosystems are connected to one another. Because these connections are via both social interactions and functional characteristics of the landscape, a social-ecological network emerges. Using social-ecological network theory, we ask how understanding the structure of interactions can lead to improved rainwater management interventions. Using a case study situated within a small sub-basin in the Fogera area of the Blue Nile Basin of Ethiopia, we build networks of smallholders based both on the biophysical and social-institutional landscapes present in the study site, with...

Promoting Health and Well-Being by Managing for Social–Ecological Resilience: the Potential of Integrating Ecohealth and Water Resources Management Approaches Ecology and Society
Bunch, Martin J; Faculty of Environmental Studies, York University; Network for Ecosystem Sustainability and Health; bunchmj@yorku.ca; Morrison, Karen E; Department of Population Medicine, Ontario Veterinary College, University of Guelph; Network for Ecosystem Sustainability and Health; karenm@uoguelph.ca; Parkes, Margot W; Health Sciences Program, University of Northern British Columbia; Network for Ecosystem Sustainability and Health; mwparkes@interchange.ubc.ca; Venema, Henry D; International Institute for Sustainable Development; Network for Ecosystem Sustainability and Health; hvenema@iisd.ca.
In coupled social–ecological systems, the same driving forces can result in combined social and environmental health inequities, hazards, and impacts. Policies that decrease social inequities and improve social cohesion, however, also have the potential to improve health outcomes and to minimize and offset the drivers of ecosystem change. Actions that address both biophysical and social environments have the potential to create a "double dividend" that improves human health, while also promoting sustainable development. One promising approach to managing the complex, reciprocal interactions among ecosystems, society, and health is the integration of the ecohealth approach (which holds that human health and well-being are both dependent on...

Software for calculation of reservoir active capacity with the sequent-peak algorithm REA
Silva,Rogério T. da; Sánchez-Román,Rodrigo M.; Teixeira,Marconi B.; Franzotti,Celso L.; Folegatti,Marcos V..
It is presented a software developed with Delphi programming language to compute the reservoir's annual regulated active storage, based on the sequent-peak algorithm. Mathematical models used for that purpose generally require extended hydrological series. Usually, the analysis of those series is performed with spreadsheets or graphical representations. Based on that, it was developed a software for calculation of reservoir active capacity. An example calculation is shown by 30-years (from 1977 to 2009) monthly mean flow historical data, from Corrente River, located at São Francisco River Basin, Brazil. As an additional tool, an interface was developed to manage water resources, helping to manipulate data and to point out information that it would be of...

RETHINKING REHABILITATION: SOCIO-ECOLOGY OF TANKS AND WATER HARVESTING IN RAJASTHAN, NORTH-WEST INDIA AgEcon
Shah, Tushaar; Raju, K. Vengama.
In the arid and semi-arid Indian state of Rajasthan, tanks and ponds have been a mainstay of rural communities for centuries. There are over 4600 large minor irrigation tanks, plus numerous johads, bandhs and pals (small water harvesting structures). This paper assesses a strategy proposed for rehabilitating 1200 of the larger tanks. It argues that treating tanks only as flow irrigation systems—which lies at the center of the mainstream thinking on rehabilitating surface irrigation systems--is very likely to result in a flawed strategy when applied to tanks. Instead, reviewing the successful experience of NGOs like PRADAN and Tarun Bharat Sangh in reviving and rehabilitating clusters of small traditional water harvesting structures at a watershed level, it...

Modeling Water Resources Management at the Basin Level: Methodology and Application to the Maipo River Basin AgEcon
Cai, Ximing; Ringler, Claudia; Rosegrant, Mark W..
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...

Community Watershed Management in Semi-Arid India: The State of Collective Action and its Effects on Natural Resources and Rural Livelihood AgEcon
Shiferaw, Bekele A.; Kebede, Tewodros A.; Reddy, V. Ratna.
Spatial and temporal attributes of watersheds and the associated market failures that accelerate degradation of agricultural and environmental resources require innovative institutional arrangements for coordinating use and management of resources. Effective collective action (CA) allows smallholder farmers to jointly invest in management practices that provide collective benefits in terms of economic and sustainability gains. The Government of India takes integrated watershed management (IWM) as a key strategy for improving productivity and livelihoods in the rain-fed and drought-prone regions. This study investigates the institutional and policy issues that limit effective participation of people in community watershed programs and identifies key...

ACCOUNTING FOR SPATIAL CHARACTERISTICS OF WATERSHEDS IN EVALUATING WATER POLLUTION ABATEMENT POLICIES AgEcon
Qiu, Zeyuan; Prato, Anthony A..
This study evaluates three agricultural nonpoint pollution abatement policies: regulating the spatial pattern of agricultural activities, ambient tax, and abatement tax/subsidy. All three policies incorporate spatial characteristics of agricultural emission loading and movement for an agricultural watershed in the Midwest. The effects of spatial variation in natural conditions and landscape features on agricultural emissions and crop yield are evaluated using a newly developed biophysical simulation model and experimental data. While the policies are equally cost effective in reducing agricultural nonpoint source pollution, their implementation feasibility is quite different.
