A bioeconomic model of reservoir aquaculture in northern Vietnam, called BRAVO, is presented. The biological model is based on a conventional von Bertalanffy growth function and the economic model is a net revenue function. The greatest source of costs for the operation are restocking costs (75...

Six methods for measuring food security are identified from the literature. The dietary intake method (DIM) and the food insecurity experienced-based measurement scales (FIEMS), the two most commonly used, were empirically tested using 1152 rural households in the Punjab province of Pakistan....

Many environmental policy issues involve conflicts between nature conservation and economic development. The economic rationale behind deciding among alternative options is predicated on some form of benefit-cost analysis (BCA). Key issues to date have been non-market valuation, the...

Conflicts of interest between irrigation and aquaculture in water use from reservoirs in Vietnam can be resolved when trade-offs in the economic value of water can be quantified over time. Determining these trade-offs can be used as a benchmark for making decisions about managing reservoirs...

If farming practices are degrading the land by enhancing salinsation and soil erosion, and the appropriate way to deal with the problem is by planting trees or regenerating native brush, farmers are faced with several questions. Assuming a rather homogenous area where cropping yields have been...

In order to maximize efficiency, should conversation contracts include incentive payments and also be put up for tender? This work uses laboratory experiments to investigate this question. We find that there exists an optimal share of performance payment which yields maximum total stewardship...

Sustainability is the paradigm of our time, yet its use as a guide to planning or decision making is clouded by its ambiguity and the multiplicity of definitions in use. In this paper we address the issue of how best to deal with the multi-faceted nature of sustainability. We outline each of the...

Three policy options for greenhouse gas abatement in the predominantly grazing systems of Western Australia are analysed. The two taxation policies (a tax on total emissions, and a tax on methane emissions only) are only effective at extreme tax rates ($85/t CO2 equivalents) where the farming...

Policy makers aiming to get private landholders to provide non-marketed environmental services need to provide efficient economic incentives. Two ideas have been explored to achieve this: linking contract payments to environmental outcomes and putting the contracts up for tender. This paper...

This paper analyzes the problem raised by quality provision in globalizing economies. When quality is a credence attribute, there is a signaling problem and quality drops to its minimum level. A way out of this under-provision equilibrium consists to rely on certification. However certification...
