The total factor productivity of the Commonwealth Trawl Sector of the Southern and Eastern Scalefish and Shark Fishery is estimated for the period 1996–97 to 2008–09 using vessel-level data and a traditional approach that captures the production decisions of fishers. The paper develops a...

Changes in net economic returns in a fishery over time can provide some indication of which direction a fishery’s economic performance is moving. However, without information on the causes of those movements, it is difficult to say if a fishery is moving closer to or further away from a point...

This paper proposes an Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index's main appeal is that it can be easily interpreted and that encompasses in a single number hydrological processes, structural constraints, water...

The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other...

Water availability in semiarid regions usually exhibits patterns of extreme variability. Even in intensively controlled basins, some users are subject to low levels of water reliability, and more vulnerable to periods of extreme scarcity. To reduce their risk exposure more flexible instruments,...

Fishers in quota-regulated fisheries find it to their advantage to discard less valuable fish at sea to increase the value of their catch. A theoretical model describing the high-grading behavior of fishers is presented, and an empirical model is derived as well as a testing strategy to test for...

The study is an empirical investigation of agrobiodivestiy conservation decisions of small farmers in the central highlands of Ethiopia. The primary objective is to measure the effectiveness of Community Seed Banking (CSB) in enhancing diversity while providing production incentives. We employed...

By the end of year 2010, each member state of the European Union (the EU) ought to incorporate 5.75% of bio-fuels in the total of fuels used for transportation purposes. In order to achieve such a target, tax incentives are implemented by the French government given that the production of...

An analysis for the implementation of the Nitrate Directive in the EU indicates that probably only three of 15 countries have implemented the directive satisfactorily. These countries are Sweden, Finland, Denmark and Austria, however other countries are in the process of getting their...

There has been a significant increase in private sector participation (PSP) in the urban water supply and sanitation (WSS) sector in recent years. However, even with increased PSP, public authorities will still have to: ensure that the service providers do not use their market power to exploit...
