QSA published its 1st Environmental Statistics Report 2012, which includes a lot of information about climate, water, air, waste, nature reserves and environmental indicators.   This new report came as a result of QSA increased attention given recently to the new statistical indicators and data, that serves the implementation of Qatar National Development Strategy 2011 – 2016 and National Vision 2030, whose developmental environmental pillar is one of its main components. The report highlights the response indicators, which is achieved through the processes of monitoring the environment, and developing laws and regulations to govern any environmental violations, that is an important environmental preservation element. It aims to reduce pollution in order to keep the environment clean and healthy. The report also shows the number of projects subject to environment impact assessment. That measure was taking to prevent the occurrence of any environmental damages, which may cost much more than the project revenues do. There are damages types that can not be repaired, such as the elimination of some organisms; thus it has become necessary to think about green growth. Throughout the year the prevailing winds are from the northwest The report indicates that Qatar's climate is extremely hot in the summer with an average maximum temperature of 39.2˚C. It is warm in winter, where it rains lightly, with an average maximum temperature of 23˚C. As to Qatar's winds, the prevailing ones throughout the year are from the northwest. It blows at an average speed of 16 km/h. Rainfall quantity does not meet the annual needs Qatar is located within arid regions, where rainfall is relatively less. Given that temperature is high most of the year, and sandy soils are dominant which leads to the loss of a large part of this water by evaporation, the processes of water harvesting and using water saving means are essential for environmental sustainability and water resources conservation. The quantity of rain falling during the last three years on the State's different regions ranged between 6 mm and 62 mm. The groundwater recharge amounted to 81 million cm. This quantity does not meet the annual needs; that's why larger quantities of water have been safely withdrawn. In addition to relying mainly on the desalination of sea water, which consumes a lot of energy and may causes environmental damages. So a long-term strategy for water supply should be set in more ustainable ways.  As to the amount of treated wastewater, it went rapidly up- from 157,500 cm in 2005 to 8,548,953 in 2011, which means it has doubled about 54 times.
