“…Barreto et al (2010) destacam que a água é utilizada como estratégia na administração de conflitos e proteção ambiental, o que justificaria o estabelecimento da gestão de BHs por meio de CBH, pois busca o equilíbrio entre a demanda e o consumo humano, dessedentação animal e irrigação. Neste sentido, Mahmoud et al (2011) em seu estudo revela que o fator crescimento populacional obriga os gestores de BHs e os stakeholders a tomarem decisões críticas sob diferentes graus de incertezas. Gaddis et al (2010) salientam que a gestão de BHs por CBHs afeta e é afetada pela sociedade, principalmente em relação à poluição.…”

“…Kaplowitz e Witter (2008) e Mahmoud et al (2011) reforçam esta justificativa, destacando que com o prolongamento da escassez hídrica exercendo pressões sobre os sistemas de gestão e distribuição de água existentes torna-se essencial a identificação e análise dos fatores que podem alterar o gerenciamento do consumo para uma eficiente gestão, incluindo as BHs. O sucesso na gestão de BHs, segundo Brody et al (2005), é realizado por meio de diferentes grupos de stakeholders, mas através de uma melhor compreensão das características socioeconômicas, demográficas e demais variáveis intervenientes.…”

RESUMOA gestão de bacias hidrográficas por meio de comitês é essencial na mediação entre a oferta e a demanda de água para consumo doméstico, industrial, agrícola, lazer, entre outros usos da água. Uma gestão exitosa pode ocorrer por meio da identificação e compreensão das características socioeconômicas, demográficas, entre outras, e assim formatar as práticas adotadas pelos comitês. Neste contexto, o escopo central deste estudo consistiu em analisar as variáveis intervenientes relacionadas aos aspectos geográficos, demográficos, socioeconômicos e a existência de comitê de bacias. A metodologia consiste na abordagem quantitativa, empregando-se uma pesquisa documental secundária e sua análise ocorreu por meio da aplicação da estatística descritiva e do teste de correlação de Pearson. Os principais resultados evidenciam que a explicação da existência de comitês de bacias hidrográficas relaciona-se com o tamanho da população que promove maior pressão à medida que aumenta. Além disso, evidenciou-se que a existência de comitês de bacias correlaciona-se com: crescimento econômico, quantidade de conflitos pelos múltiplos usos, coleta de esgotos e nível de degradação da qualidade ambiental. Conclui-se, portanto, que de fato existem variáveis intervenientes para a existência de comitês de bacias e que eles são necessários para a gestão eficiente destas variáveis.Palavras-chave: demográficos, geográficos, Pearson test, recursos hídricos, saneamento, socioeconômicos.

“…Researchers proceed with scenario construction by selecting or developing models or other data generation procedures that can adequately represent the conceptual model, collecting and processing model input data, running the models for each scenario, and processing model output data (scenario outcomes; Liu et al 2008b). In their application of this framework, Mahmoud et al (2011) provide a particularly comprehensive description of the scenario construction phase.…”

Abstract. Land cover and land use changes can substantially alter hydrologic ecosystem services.Water availability and quality can change with modifications to the type or amount of surface vegetation, the permeability of soil and other surfaces, and the introduction of contaminants through human activities. Efforts to understand and predict the effects of land use decisions on hydrologic services-and to use this information in decision making-are challenged by the complexities of ecosystem functioning and by the need to translate scientific information into a form that decision makers can use. Hydrologic modeling coupled with scenario analysis can (1) elucidate hydrologic responses to anticipated changes in land use and (2) improve the utility of scientific information for decision making in a manner that facilitates stakeholder involvement. Using a combination of general concepts and concrete examples, this paper summarizes hydrologic consequences of land use changes and describes the use of modeling and scenario analysis to inform decision making. Two case studies integrate the concepts raised in the paper and illustrate how an approach employing modeling and scenario analysis offers a potentially powerful way to link research on hydrologic services with decision making.

“…Previously, plenty of modeling technologies were applied to water resources and farmland use system planning with non-point source pollution mitigation (Satti et al, 2004;Chen et al, 2005;Riquelme and Ramos, 2005;Victoria et al, 2005;Kondilia and Kaldellis, 2006;Gregory et al, 2006;Khare et al, 2007;Castelletti et al, 2008;Qin et al, 2011;Mahmoud et al, 2011;Deviney Jr. et al, 2012;Zarghami and Hajykazemian, 2013;Canter et al, 2014). For example, Satti et al (2004) used the GIS-based water resources and agricultural permitting and planning system to simulate the effect of climate, soil, and crop parameters on crop irrigation requirements.…”

Abstract. In this research, a dual-inexact fuzzy stochastic programming (DIFSP) method was developed for supporting the planning of water and farmland use management system considering the non-point source pollution mitigation under uncertainty. The random boundary interval (RBI) was incorporated into DIFSP through integrating fuzzy linear programming (FLP) and chance-constrained programming (CCP) approaches within an interval linear programming (ILP) framework. This developed method could effectively tackle the uncertainties expressed as intervals and fuzzy sets. Moreover, the lower and upper bounds of RBI are continuous random variables, and the correlation existing between the lower and upper bounds can be tackled in RBI through the joint probability distribution function. And thus the subjectivity of decision making is greatly reduced, enhancing the stability and robustness of obtained solutions. The proposed method was then applied to solve a water and farmland use planning model (WFUPM) with non-point source pollution mitigation. The generated results could provide decision makers with detailed water supply-demand schemes involving diversified water-related activities under preferred satisfaction degrees. These useful solutions could allow more in-depth analyses of the trade-offs between humans and environment, as well as those between system optimality and reliability. In addition, comparative analyses on the solutions obtained from ICCP (Interval chance-constraints programming) and DIFSP demonstrated the higher application of this developed approach for supporting the water and farmland use system planning.
