The growing geographic disconnect between consumption of goods, the 26 extraction and processing of resources, and the environmental impacts associated with 27 production activities makes it crucial to factor global trade into sustainability assessments. 28 Using an empirically validated environmentally extended global trade model we examine the 29 relationship between two key resources underpi...

Ground water resources of atolls, already minimal due to the small surface area and low elevation of the islands, are also subject to recurring, and sometimes devastating, droughts. As ground water resources become the sole fresh water source when rain catchment supplies are exhausted, it is critical to assess current groundwater resources and predict their depletion during drought conditions. ...

The principles of the Rio Conference (1992) and Agenda 21 address the pressing problems of today and also aim at preparing the world for the challenges of this century. The conservation and management of resources for development are the main foci of interest, to which chemistry will have to make a considerable contribution. Since base chemicals are produced in large quantities and important pr...

In their article ‘Freshwater savings from marine protein consumption’ (2014 Environ. Res. Lett. 9 014005), Gephart and her colleagues analyzed how consumption of marine animal protein rather than terrestrial animal protein leads to reduced freshwater allocation. They concluded that future water savings from increased marine fish consumption would be possible. We find the approach interesting an...

One of the central puzzles in the study of sociocultural evolution is how and why transitions from small-scale human groups to large-scale, hierarchically more complex ones occurred. Here we develop a spatially explicit agent-based model as a first step towards understanding the ecological dynamics of small and large-scale human groups. By analogy with the interactions between single-celled and...

The growing geographic disconnect between consumption of goods, the extraction and processing of resources, and the environmental impacts associated with production activities makes it crucial to factor global trade into sustainability assessments. Using an empirically validated environmentally extended global trade model, we examine the relationship between two key resources underpinning econo...

The concern over ensuing freshwater scarcity has forced the developing countries to delve for alternative water resources. In this study, we examined the potential of stagnant surface water bodies (SSWBs) as alternative freshwater resources in the densely populated Chittagong metropolitan area (CMPA) of Bangladesh--where there is an acute shortage of urban freshwater supply. Water samples were ...

Thermal technologies for the treatment of waste are once again attracting interest, particularly in Europe and North Amerca, as landfill space becomes scarcer and landfill regulations become more stringent. Plasma technologies can be used to destroy waste at high temperatures, using electricity to convert waste into a fuel gas and an inert rock. The Plasma Arc Waste Destruction System’s (PAWDS)...

The knowledge-intensiveness of economy today is one of the reasons for researchers to consider that the foundation of organizational competitiveness has shifted from physical and material resources to intangible resources, and knowledge in particular [1]. The adoption of Knowledge Management (KM) as company practice was driven by large organizations and consulting companies world-wide. The comp...
