Kenya over the last few decades, and the change from a nomadic lifestyle to communally owned ranches, wildlife in the Samburu District is under threat from deforestation, land degradation, overgrazing by livestock, and unsustainable water use. Alexander Njue, who is also involved in a separate Earthwatchsponsored project studying the wildlife habitats in this area, hopes that wildlife can also ...

With the ever-increasing population of the world (expected to reach 9.6 billion by 2050), and altered life style, comes an increased demand for food, fuel and fiber. However, scarcity of land, water and energy accompanied by climate change means that to produce enough to meet the demands is getting increasingly challenging. Today we must use every avenue from science and technology available to...

Bangladesh is one of the most densely populated countries with immense pressure on agricultural land in rural areas. Mainstream households depend either agriculture or its associated activities for their livelihood. However, distribution highly skewed, majority them are landless. Under such a scarce situation, farmers areas have been gradually inclining towards tenancy. Present study steered to...

That the scarcity of objects enhances their value is a widely known principle in the behavioral sciences. In addition, research has demonstrated that attaching high value to an object produces biased perceptions of its scarcity. Three studies applied this bidirectional link between scarcity and value to the meaning of death, testing the prediction that death represents the scarcity of life. In ...

Owing to food scarcity and to the high densities that vertebrates often reach on islands, typical insect- and seed-eaters widen their feeding niche and interact with a greater fraction of species than their mainland counterparts. This phenomenon, coined here 'interaction release', has been previously reported for single species but never for an entire community. During 4 years, we gathered data...

This chapter reviews existing long term water demand forecasting methodologies. Based on an extensive literature review, it shows that the domain has benefited from contributions by economists, engineers and system modelers, producing a wide range of tools, many of which have been tested and adopted by practitioners. It illustrates, via three detailed case studies in the USA, the UK and Austral...
