adopting a policy and deciding on long-term investment in the mining industry by a government orprivate sector actors depends strongly on the ability to predict the scarcity of mineral reserves. changein scarcity of mineral reserves is a function of several technological and non-technological factors.among them, change in technology is the most significant factor affecting scarcity. this paper ...

This paper presents a global scale assessment of the impact of climate change on water scarcity. Patterns of climate change from 21 Global Climate Models (GCMs) under four SRES scenarios are applied to a global hydrological model to estimate water resources across 1339 watersheds. The Water Crowding Index (WCI) and the Water Stress Index (WSI) are used to calculate exposure to increases and dec...

The impact of water use in areas with abundant freshwater resources should not be the same as areas with limited resources. This impact is quantified as water scarcity footprint. The monthly water stress index with reference to environmental water requirement is proposed as a characterization factor. The biofuel policies of Thailand—cassava and sugarcane for bioethanol, and oil palm for biodies...

Most scarcities that underpin health disparities within and among countries are not natural; rather, they result from policy choices and the operation of social institutions. Using examples from the United States of America: the Chicago heat wave and hurricane Katrina, this paper develops "denaturalizing scarcity" as a strategy for enquiry to inform public-health ethics in an interconnected wor...

Chile contains some of the driest areas in the world, yet human activities in these areas require large volumes of water, the result is regions experiencing high water scarcity leading to environmental degradation, conflicts and reduced industrial productivity. The aim of this paper was to quantify the water scarcity in the central and northern regions by calculating the water scarcity index—th...
