ABSTRACT Customary land tenure claims provide a useful analogy for customary access and usage rights to critical water resources. In an increasingly water‐constrained future, such rights are at risk of political and economic contestation and local communities may find themselves abruptly divested of critical water resources just when they need them most. The new nation of East Timor is not abundantly endowed with water and inland sources are particularly vulnerable to the impacts of reduced rainfall and groundwater contamination. Recently McWilliam (2003) has suggested that in future disputes over Timorese sea tenures, the recognition of customary access or exclusive property rights to specific water resources will depend upon clearly articulated evidence of longstanding cultural associations and interactions with the aquatic landscape. The ethnographic literature provides substantiating accounts of the centrality of water in the local cosmologies of various East Timorese ethnic groups. This paper extends McWilliam's marine argument to inland water resources by reviewing the salient ethnographic evidence for Bunaq, Mumbai and Eastern Tetum populations to show that water is a key organising metaphor in the expression of Timorese kingroup affiliation, social identity and power relations. Local ritual practices further affirm customary rights of access and water use. There is an urgent need for such customary rights to water to be recognized in the current redistribution and demarcation of internal boundaries in East Timor, as well as in future struggles against vested economic and political interests.  相似文献

Policy scholars have effectively leveraged policy process models, theories, and frameworks to respond to a variety of important environmental questions. For example, how do environmental issues arrive on the agendas of policymakers? What factors contribute to environmental policy change? What are the designs and effects of institutions (e.g., policies or cultural norms) on environmental governance? In this review, we survey the field of policy process scholarship, focusing on environmental governance, with three objectives. The first objective is to catalog the policy process models, theories, and frameworks most often featured in studies of environmental governance. The second is to capture the methodological choices commonly employed in the application of these models, theories, and frameworks in environmental domains. The third is to identify how these approaches deal with issues central to environmental governance research, including time, space, and policy scale. We aim to identify trends and strategies for integrating key considerations of scale into empirical policy process scholarship.  相似文献

A geophysical survey (side-scan sonar and high-resolution sub-bottom profiling) combined with established chrono- and bio-stratigraphic markers are used to reconstruct the evolutionary history of Lower Lough Erne, northwestern Ireland since the end of the last glacial. Discrete acoustic units define four prominent sedimentation cycles, one Late-glacial and three Holocene, within the seismic stratigraphy. Basin development is predominantly controlled by climate until the Mid Holocene when the effects of cultural activity are related to pronounced signatures in the seismic record. An enhanced reflector marking the termination of the Early Holocene sedimentation cycle is associated with the elm decline and forest clearance during the Neolithic (between approximately 5800 cal. BP and 5300 cal. BP). The associated increase in sediment input, by infilling minor topographic lows and basins, has a smoothing effect on the morphologic expression of the original basin. Onlapping and truncated reflectors in the penultimate acoustic unit define further modification of lake bed relief by removal of sediment from the system during engineered lowering of the lake levels that began in the 1880s. Acoustic anomalies identified on the side-scan sonar data are linked with cultural activity and are identified as having the potential to facilitate the recent establishment and migration of invasive zebra mussels through the Erne system.  相似文献
