Increasing water demand due to population growth, irrigation expansion, industrial development, and the need for ecosystem improvements under mounting investment costs for developing new water sources calls for the efficient, equitable and sustainable management of water resources. This is...

Este trabalho tem como objetivo analisar a relação de path dependence no sistema econômico e institucional do álcool combustível no Brasil. O etanol, após fases de crescimento e desafios, tornou-se parte da matriz energética brasileira. Esta trajetória reflete a persistência de uma rota...

The interconnections of agriculture and energy markets have increased through the rise in the new biofuel agribusinesses and the oil–ethanol–corn linkages. The question is whether these linkages have a causal structure by which oil prices affect commodity prices and through these links,...

The understanding of how allocation decisions can maximise the economic returns to the community from water for irrigation has received little attention, but is a significant issue for regional councils, those interested in water allocation policy development, and for irrigated farmers. There is...

This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their...

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...

Economic-engineering cost data and a simulation model were used to analyze the impact of sales density, size of sales area, sales volume, and equipment configuration on costs of bulk fuel delivery by cooperatives. Fixed costs accounted for the majority of delivery costs regardless of sales...

Recent increases in the price of crude oil have led to a rise in the prominence of corn-based ethanol as an alternative source of energy. As a result linkages have been established between commodity and energy prices. The aim of this study is to determine if soybeans, corn, wheat, oil, and...

Este trabalho buscou evidenciar a incompatibilidade existente entre os interesses econômicos em contraponto com os interesses socioambientais acerca da produção de biocombustíveis – biodiesel e etanol – no Estado de Rondônia e qual o auxílio da controladoria neste contexto. O estudo...

A USGS analysis of land change data from satellite imagery and field observation indicated that 217 square miles of Louisiana's coastal wetlands were converted to open water because of Hurricanes Katrina and Rita. Because of their physical location and marine-dependence, commercial and...
