Because of climate change, water will become even more scarce in many arid parts of the world. The implications for sanitation, health and agriculture are serious. No doubt, this precious resource must be used efficiently. Doing so will help to reduce poverty, prevent epidemics and save energy, says Thomas Kluge of the Institute for Social-Ecological Research (ISOE) in Frankfurt.

Wetlands ecosystems are a natural source of local, regional and global significance. Historically their high level of plant and animal (especially bird) diversity is perhaps the major reason why wetland protection has become a high priority worldwide, supported by international agreements, such as Ramsar Convention and the International Convention of Biological Diversity.

In the present studies, attempts are made to optimize digestion time, initial feed pH, feed temperature and feed flow rate (organic loading rate, OLR) for maximum yield of methane gas and maximum removal of chemical oxygen demand and biological oxygen demand (BOD) of food processing industry wastewaters in three-phase fluidized bed bioreactor.

Consecutive years of drought are making it imperative for Israel
to take measures to reduce the growing gap between water supply
and demand.

It is time we began to live differently. But if you believe that governments and power and water utilities can bring about that change, you need to think again. The change has to begin with us.
