The need to meet basic human needs in a sustainable manner is a major challenge nowadays for developing and
developed countries. Key issues involve depletion of fossil fuels, global warming, water scarcity, rise in energy demand,
loss of biodiversity and the human health impact which are exaggerated with the global expansion. The global demand for
the two essential resources (water and energy) is drastically increasing due to economic expansion, population growth and
increasing living standard in emerging countries. In 30 years, it is expected that energy demand will be projected by 50%
while water withdrawal could go beyond 50% in developing countries and 18% in developed countries over the same period
