Independent verification of fossil-fuel based CO2 and other greenhouse gas emissions: Example from the Netherlands and possibilities for Qatar
More LessAuthors: Harro A.J. Meijer and Wouter PetersGrowing concern about anthropogenic influence on the climate system due to emissions of greenhouses gases into the atmosphere causes governments everywhere around the world to adopt fossil fuel use reduction policies. However, to test if various government-launched measures and incentives really are effective, the fossil fuel based CO2 emissions into the atmosphere should be independently verified. To date, in Read More

CO2 and renewable electricity as feedstock for fuels production: New pathways using existing technologies
More LessAuthors: Ruud Van Den Brink, Wim Haije and Stephane WalspurgerThe case for CO2-based fuels Coal and natural gas are still the main fuels for electricity generation. Traditional power plants have many advantages: they are very reliable and can relatively easily be ramped up and down to follow the electricity demand. However, their one disadvantage, their huge CO2 emission, is so big that they are replaced by alternatives. These alternative electricity generation sources, Read More

Renewable energy in the GCC: Reducing the fuel and carbon footprint
More LessAuthors: Rabia Ferroukhi, Arslan Khalid and Shashi PrakashThe harsh climate of GCC, rapid industrialisation and energy subsidies have led to a per capita energy consumption that is much higher than the larger economies of the US, China and the EU. The situation is likely to become worse as more electricity, desalinated water and gasoline will be needed to fuel the ambitious national plans for industrial and economic growth. Localised shortages of natural gas already exist, and the Read More

Managing of invasive species of red palm weevil (Rhynchophorus ferrugienus)
More LessRed palm weevil-RPW (Rhynchophorus ferrugienus Olive, Coleoptera, Curculionidae) was first observed in India in 1917 as a serious pest on date palm (Phoenix dactylifera L.). It was introduced in Arabian Gulf countries in the mid-1980s and now considered to be one of the most destructive insects on date palm. The larvae are responsible for damaging and they cause the death of palm tree. There is no data available about t Read More

Adaptive water resources management under global environmental change: Examples from a small semiarid Mediterranean municipal district
More LessAuthors: Ioannis Tsanis and Aristeidis G. KoutroulisClimate change is expected to have a significant impact on the hydrologic cycle, creating changes in freshwater resources. Globally, the supply of freshwater far exceeds human requirements. However, by the end of the 21st century, these requirements will begin to approach the total available water. Regionally, water demand for various sectors already exceeds supply. This will most probably get worse with increasing Read More
