Examining ‘willingness to participate’ in community-based water resource management in a transboundary conservation area in Central America
Operationalizing integrated water resource management (IWRM) often involves decentralization of water management via community-based management (CBM). While attention has been given to the components leading to successful CBM, less is known about what factors motivate people's willingness to participate (WTP) in such programs. This study analyzed factors that influence household WTP in CBM in ...

A heuristic analysis of equity and equality in the institutionalisation of property rights: the Baliraja water distribution experiment, India
Natural resource management perceived as a search for institutions that can ensure simultaneous fulfilment of three goals: productivity (or efficiency), sustainability and equity. In this article, we study the implications of pursuing the goal of equity in the management of surface water resources for irrigation with a heuristic model incorporating a Leontief-type fixed production function. The ...

Temporal variations of runoff in a rapidly urbanizing semi-arid Chinese watershed
Rapid urbanization on streamflows may directly affect or be restricted by the sustainability of local water resources. This is particularly true for arid/semiarid areas such as the Wulanmulun River watershed in the rapidly-developing Ordos region of north central China. From 1997 to 2012, the gross domestic product (GDP) of the region increased fifty-fold, while the urban area grew by a ...
