Factors affecting water availability. Low (less than 10% of available water is used): low water stress. Sub-drainage areas with a moderate threat to water availability (Between 10% and 20% of water use) are the 05A (Upper South Saskatchewan), 05B (Bow) and 05C (Red Deer). Engage students in thinking about how water is distributed on Earth. >> /PCSp 4 0 R There are a few exceptions; specifically, in some sub-drainage areas in the southern part of the Prairies (e.g. All the other regions of the country are in the low threat to water availability category (Less than 10% of water use). Sub-drainage areas that have existing or potential water scarcity problems like the southern prairies were the initial focus of the project. /F8 8 0 R 13 0 obj 05B-Bow, 05J-Qu’Appelle and 05M-Assiniboine). It will help to inform the Canadian public, policy makers, other decision makers and interested groups about water supply and demand. ), water quality (how much treatment is needed before it is clean enough to use? The goal of the initiative is to create an indicator that can be used to provide a nationally and regionally relevant picture of water availability. High (more than 40% of available water is used): severe water stress. /SM 0.02 /SA true You can find it in the atmosphere above us, in the ocean, rivers and lakes around us, and in the rocks below us. Factors affecting water supply. It should be noted that, due to lack of available historical data, the northern part of the province of Quebec has not been evaluated. In Quebec, the water availability threat is considered low in the entire province, meaning that there was ample water during 2005 and 2007 to meet user needs. Water availability, both as surface water and groundwater, is essential for agriculture, human consumption, industry, and energy generation. [/Pattern /DeviceRGB] This is caused by large industrial and municipal water use and a low inland surface water supply. As water availability is reduced, community composition of organisms will shift to adapt to different conditions. Marine organisms can be maintained in either natural or artificial seawater; the latter has the advantage of being initially… Freshwater Availability Water is the fundamental ingredient for life on Earth. Sub-drainage areas with high threat to water availability (More than 40% of water use) are the 05F (Battle), 05J (QuAppelle), 05N (Souris), 11A (Missouri), 02F (Eastern Lake Huron), 02G (Northern Lake Erie) and 02H (Lake Ontario and Niagara Peninsula). /F6 6 0 R /ExtGState << Moderate (between 10% and 20% of available water is used): water availability becomes a constraint on development; significant investment is needed to provide for adequate water supply. /Resources 12 0 R >> Medium (between 20% and 40% of available water is used): both water supply and water demand need to be managed; conflicts among competing uses will need to be resolved. All the other regions of the country are in the low threat to water availability category. /F7 7 0 R << In calculating this ratio, yearly average surface water supply is based on a 30-year period (or on as many consecutive years as data is available). Availability of Fresh Water How fresh water is available on Earth? This is illustrated in the map below. endobj /Type /Page /MediaBox [0 0 612 792] /Pattern << Water scarcity can mean scarcity in availability due to physical shortage, or scarcity in access due to the failure of institutions to ensure a regular supply or due to a lack of adequate infrastructure. Pressures - including rapid urbanization, industrial expansion, agricultural intensification, and the impacts of climate change - stress water supply and affect the health of aquatic ecosystems. Map of the Water Demand and Availability Indicator for 2007 at the sub-drainage area level. In order to compare the 2005 and 2007 WAI results to average values over time, an historical ratio was calculated. << Water Availability Water is constantly moving on the Earth between the atmosphere, ocean, rivers and streams, snowpacks and ice sheets, and underground. As a part of the water cycle, Earth's surface-water bodies are generally thought of as renewable resources, although they are very dependent on other parts of the water cycle. To calculate the ratio, a geographical information system is used to analyze water use data from several federal water use surveys and streamflow values from Water Survey of Canada HYDAT stations in a spatial and temporal frame relevant to water availability issues. Water availability refers to the volume of water in our rivers compared with the amount of water we are using. Show the Earth from Space photograph. The southern part of the Prairie region (Alberta, Saskatchewan and Manitoba) is known historically as a dry and arid area where low precipitation means a smaller water supply than in other parts of the country. ����`؝�5����,����Ѳ4��u��;"�iFf+X�du�LkMw4�G��ӿ~���o�~z������w�NzP���`����O_���������������>� �*������&� ��ݿ�O�7���෿�O��/3� ����0*�_*�/��1���د��ϧ���� O�Sz"��������U]���n������OE9A�Y��z��_~;��kt~���}���+�#��/ÿ )~��)��&�) � l��k�`����[��de�Y�%�7gc��a��l���W��~��"��� There are several reasons why global water supply is not even.
