Residents of Southern Africa depend on rangeland for food, livelihoods, and ecosystem services. Sustainable management of rangeland ecosystems requires attention to interactive effects of fire and grazing in a changing climate. It is essential to compare rangeland responses to fire and grazing...

We consider the problem faced by firms operating in a foreign country characterized by weak governance. Our focus is on extortion based on the threat of expropriation and bureaucratic harassment. The bureaucrat's bargaining power is characterized by a general extortion mechanism adapted from the...

This paper reviews a range of issues relating to tradable carbon dioxide quotas. It considers the economic principles on which they are based, compares them with alternative carbon abatement policies, and reviews many aspects of how tradable quotas would be implemented in practice.

Are efficiency improvements in the use of natural resources the key for sustainable development, are they the solution to environmental problems, or will second round effects –so-called rebound effects- compensate or even overcompensate potential savings, will they fire back? The answer to...

Economic choices influenced by animalistic instincts in an ethically neutral framework have not only resulted in huge disparity in distribution of income, wealth and standard of living, but, as we now realize, it has also resulted in unprecedented loss to ecology and environment with...

Land cover change impacts ecosystem function across the globe. The use of land cover data is vital in the detection of these changes over time; however, most available land cover products, such as the National Land Cover Dataset (NLCD), are produced relatively infrequently. The most recent NLCD...

The Adelaide-Mt Lofty Region of South Australia is an exemplar, in microcosm, of the issues confronting biodiversity conservation in a world of increasing population and a drying, fire-prone environment. At just 0.1% of Australia’s terrestrial land mass, this area is largely peninsular and...

In-depth understanding about the vertical distribution of soil organic carbon (SOC) density is crucial for carbon (C) accounting, C budgeting and designing appropriate C sequestration strategies. We examined the vertical distribution of SOC density under different land use/land cover (LULC)...

In this article, we argue that research on land reform in the nation of Zimbabwe has overlooked possibilities of integrating geospatial methods into analyses and, at the same time, geographers have not adequately developed techniques for this application. Scholars have generally been captured...

Changes in the hydrology of sediments in tidal marshes or landfills may affect the uptake of metals in the vegetation. Leaf and stem samples of <i>Salix cinerea</i> (grey sallow) were collected during four consecutive growing seasons at six contaminated plots on a polluted dredged sediment landfill and...
