The current rate of urbanization is one of the global megatrends, which will manifest itself in many of the challenges faced in the upcoming decades. UN reports estimate that nearly 70% of the world’s population will be urban by 2050. The way in which cities deal with this rapid rate of urbanization will determine whether international objectives such as Sustainable Development Goal 11, aimed at making cities and human settlements inclusive, safe, resilient, and sustainable, will be achieved. Urbanization has further impacts on many more of the goals defined in the UN 2030 Agenda on Sustainable Development. Achieving these goals … Continue reading →

Introduction to Solar Pond

A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond. When solar energy falls onto the pond, it heats the water, splitting it into three sections: the first section is the uppermost layer, or Surface Zone, containing fresh water with a low level of salinity. This owes to the fact that salts gather at the bottom. The second layer is the middle layer, called the insulating layer or Insulation Zone, whose … Continue reading →

The water-food linkage represents an important and vital nexus in the Arab countries. Under the current unstable food security situation (fluctuating energy prices, poor harvests, rising demand from a growing population, the use of biofuels and export bans have all increased prices), the ability for the Arab countries to feed their growing population is severely challenged by competition over increasingly limited water resources. Agriculture is currently challenged by competition among sectors on available water resources. While the majority of water in the Arab region is used inefficiently in the agricultural sector (about 85% with less than 40% efficiency), which is … Continue reading →

Food waste is a huge issue in Qatar. In 2012, a massive 1.4 million metric tonnes of food was consumed and wasted in Qatar. This figure, divided by the then population of 2.05 million, equates to an average of 636 kilograms (kg) of food per person for the year, or 1.74 kg per day. Given the benchmark of two kg per person per day (preferably nutritious fare that does not contain too many kilojoules), that does not sound too excessive. But if you remove the young, elderly, short-term visitors/workers and people who consume less than two kg per day from the … Continue reading →
