“…In the case of anthropogenic indicators, uncertainty about their use is due to a lack of familiarity among professional ecologists. New methods that integrate anthropogenic and ecological indicators therefore need to ensure that the indicators selected meet the following standards (see also, Romstad, 1999;Dale and Beyeler, 2001;Manoliadis, 2002):…”

Participation by local communities in the assessment and monitoring of efforts to implement global environmental conventions (GECs), such as Convention on Biological Diversity (CBD) and the UN Convention to Combat Desertification (UNCCD), is a topic of growing interest worldwide. Previous implementation efforts were constrained by the lack of a methodological framework that integrates local knowledge and ecological methods. This study, conducted with assistance from Maasai herders in northern Tanzania, evaluated a socio-economic and ecological framework for integrating local communities into assessments of the GECs. To reach decisions related to CBD, herders used livestock grazing suitability (GS) and proxy indicators of biodiversity, while to reach decisions related to CCD herders used potential grazing capacity (PGC) related to the risk of degradation. We proposed criteria for indicator selection and developed step-wise research methods to assess performance of the indicators at spatial scales. The ecological and anthropogenic indicators were then analysed using a correlation matrix to evaluate management decisions. We showed that changes in ecological indicators influenced herder decisions. The anthropogenic indicators for potential were more sensitive to changes in soil degradation, range conditions and trends; while the decisions related to GS were more sensitive to the majority of the proxy indicators of biodiversity. The decisions reflected the potential responses to management, which had implications for CBD and CCD. Because decisions constitute a multiplicity of activities, the responses by local communities could be related to the potential role played by each indicator in the implementation of the convention at the local level.

RESUMO -Muitos esforços e recursos têm sido despendidos com o objetivo de restaurar matas ciliares sem que tenham sido estabelecidos procedimentos para avaliação e monitoramento das áreas em restauração. Neste estudo, a cobertura de copas foi analisada como um indicador para avaliar os reflorestamentos de restauração. Em seis reflorestamentos de restauração com idades variando entre 1 e 3 anos, localizados no Médio Vale do Rio Paranapanema, São Paulo, Brasil, foram realizados levantamentos da estrutura da comunidade e estimada a cobertura pelo método da interseção na linha. A cobertura apresentou correlações significativas com idade (r = 0,8140), altura (r = 0,8002), área basal (r = 0,7949), e diâmetro à altura do peito -DAP (r = 0,7234) e foi considerada um indicador adequado para avaliar a evolução estrutural dos reflorestamentos, na faixa de idade enfocada neste estudo (até 36 meses). O modelo para determinação da taxa de cobertura de copas (Y) esperada em função da idade (X) dos plantios (meses) com melhor desempenho foi o modelo recíproco (Y = a + b / X). Entretanto, outros modelos com melhores resultados de ajuste podem ser gerados caso seja considerado todo o espectro de variação de idades e de qualidade de sítio, que podem exercer influência na evolução da cobertura.Palavras-chave: Indicadores, matas ciliares e restauração.ABSTRACT -Much inspection efforts and funds have been expended with the aim of restoring riparian forests, in spite of the absence of clearly defined procedures to assess the reforested areas. In this study, canopy cover is analyzed as an indicator to be easily and precisely applied to evaluate the efficacy in forest restoration. Six reforested areas ranging from one to three years old, located at the Mid-Paranapanema Valey, São Paulo State, Brazil, were included in the structural analysis that supported this study. Crown cover estimated by line interception showed significant correlations with age (r = 8140); height (r = 8002); basal area (r = 7949) and diameter at breast height -DBH (r = 7234) and was considered a suitable indicator to assess the structural evolution of planted riparian forests at the ages comprised by this study (up to 36 months). The best equation for estimating crown cover rate by line interception (Y) as a function of age (X) was determined (Y = a + b / X). Better equations can be obtained if the whole range of ages and site variation are considered.

“…Numerous researches in the realm of water management have been conducted with application of OWA and CP methods. Manoliadis (2002) constructed a CP-based framework for developing ecological indicators. Shiau and Lee (2005) employed CP to solve conflicting multi-objective problems associated with derivation of optimal hedging rules for a water-supply reservoir.…”

Abstract:The prerequisite of designing a water quality monitoring system is providing river health assessment (RHA) which is a complex issue. To do so, the present paper creatively employed two risk-based multi-criteria decision-making methods (MCDMs) namely, ordered weighted averaging (OWA) and compromise programming (CP) to consider different risk potentials, and mitigate uncertainty associated with water quality management. Based on the results, methodologically, a mutual relationship was observed between ranking of CP and OWA. The neutral and optimistic priorities by OWA were completely corresponded with the CPs ranking with respect to p = 1. On the other hand, ascending values of p in CP represented more similarity to the pessimistic view-point of OWA. Technically, both the models illustrated that the most hazardous water quality conditions belonged to 'Taleghan-River' which was a pivotal finding because it is the most important river of the Taleghan basin. Overall, consideration of risk-attitudes in the computational process of decision-making provided different decision priorities. Due to the fact that Taleghan-River is one of the important sources of drinking water for Tehran, Karaj, and Qazvin cities, a strict decision making is recommended.Keywords: water quality monitoring; river health assessment; RHA; multicriteria framework; risk-attitude; Taleghan basin. 64 A.
