Introduction Economic theory tells us that increases in the relative prices of natural resources should cause farmers to switch to techniques that use fewer farming resources. The adoption of resource-conserving technology is one possible response that can lead toward a more environmentally sustainable outcome. Do farmers respond to changes in natural resource prices and quality by adopting ava...

Bioenergy with carbon capture and storage (BECCS) is crucial in many stringent climate scenarios. Although irrigation can enhance BECCS potential, where to what extent it global potential are unknown when constrained by preventing additional water stress suppressing withdrawal of nonrenewable resources. With a spatially explicit representation bioenergy crop plantations cycle an internally cons...

The paper presents two new results for the Dasgupta-Heal-Solow-Stiglitz model with an essential nonrenewable resource: (1) the pattern of resource extraction can be more important for sustainable growth than the pattern of saving when the Hotelling Rule modifier is not small enough; (2) the qualitative behavior of the long-run per capita output can be examined along any smooth enough path of ex...

INTRODUCTION Present and future world shortages and increasing petroleum costs have stimulated the search for alternate renewable and nonrenewable energy sources. Sugarbeets (Beta vulgaris L.) and sugarcane (Saccharum app.) have high potential as a feedstock for conversion to alcohol as a practical renewable energy source. Sugarbeets have many desirable characteristics such as: storage of 40 to...

ing from the technical measurement difficulties, there are a number of general benefits that accrue to society from its interaction with any large-scale ecosystem such as coastal wetlands (Pearce and Turner 1990). Ecosystems supply both stock and flow resources that can be used as direct and indirect inputs to production and consumption activities, thereby generating productivity and growth in ...

Balancing groundwater depletion, socioeconomic development and food security in Saudi Arabia will require policy that promotes expansion of unconventional freshwater supply options, such as wastewater recycling and desalination. As these processes consume more electricity than conventional freshwater supply technologies, Saudi Arabia's electricity system is vulnerable to groundwater conservatio...
