This is caused by large industrial and municipal water use and a low inland surface water supply. >> Although the Earth’s surface is … /SMask /None>> 5 0 obj The 05B (Bow), 05J (QuAppelle) and 05M (Assiniboine) sub-drainage areas have a higher threat to water availability based on this analysis compared to the 2005 and 2007 ratio values. >> >> This indicator is derived by calculating the ratio of water demand to water availability at the sub-drainage area scale (representing 164 watersheds across Canada) on an annual basis. A case study, with results for 2005 and 2007 in the Mixed Grasslands sub-drainage areas of southern Alberta and Saskatchewan, was published in the 2009-2010 Canada Water Act Annual Report What follows are the first national results of the initiative. While there are sufficient freshwater resources at the global level to enable continued agricultural and industrial development, the long-term sustainable use of water resources is of growing concern.1 This is particularly the case when considering the intrinsic disparity in water quality and availability … 4 \( C \) 2 0 1 1 N o k i a C o r p o r a t i o n a n d / o r i t s s u b s i d i a r y \( - i e s \)) /Type /Page The definition of freshwater is water containing less than 1,000 milligrams per liter of dissolved solids, most often salt. Sub-drainage areas with a moderate threat to water availability (Between 10% and 20% of water use) are the 05A (Upper South Saskatchewan), 05C (Red Deer) and 05M (Assiniboine). In order to compare the 2005 and 2007 WAI results to average values over time, an historical ratio was calculated. High (more than 40% of available water is used): severe water stress. *��� ��. endobj As water availability is reduced, community composition of organisms will shift to adapt to different conditions. /CSpg /DeviceGray Freshwater ecoregions with high numbers of urbanites with insufficient water (Fig. endobj /Font << << Freshwater seems abundant, but when accounting for all the water on Earth, it's in limited supply. Map of the Water Demand and Availability Indicator for 2005 at the sub-drainage area level. Freshwater Availability Water is the fundamental ingredient for life on Earth. >> 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. /MediaBox [0 0 612 792] Freshwater comprises just 2.5% of the total global water; 68.7% of this freshwater is in the form of ice and glaciers; 30.1% forms groundwater; and 1.2% forms surface water (Gleick, 1993). All the other regions of the country are in the low threat to water availability category. Low (less than 10% of available water is used): low water stress. Annual freshwater withdrawals, industry (% of total freshwater withdrawal) Level of water stress: freshwater withdrawal as a proportion of available freshwater resources. /Contents 10 0 R /ExtGState << 4 0 obj The resulting ratios are divided into four categories based on the Organisation for Economic Co-operation and Development (OECD) classification scheme provided belowFootnote1: In Northern Canada (Yukon, Northwest Territories, Nunavut, Labrador and northern parts of the provinces of British-Columbia, Alberta, Saskatchewan, Manitoba, Ontario and Quebec) some sub-drainage areas were merged for purposes of data analysis due to the low levels of human activity and the large surface water supply produced by the rivers. x��=ˎ��q�� For “water use,” an average value for the survey years 2005 and 2007 was employed. However, it is becoming increasingly threatened. This region has ample water to meet the different demands placed on the resource at the sub-drainage area level. << For enquiries, contact us. /Length 11 0 R As a result, the indicator shows a moderate to high threat to water availability. ), water quality (how much treatment is needed before it is clean enough to use? In this region of the country, the agricultural and industrial sectors are large users of surface water. In this region, the supply-demand ratio is below 10%; meaning the threat to water availability is “Low”. The Sub-drainage area with a medium threat to water availability (Between 20% and 40% of water use) is the 05B (Bow) and the 08NM sub-sub drainage area (Okanagan). y�o�Wk&�ʕ7�_o�3bw:ec03v�������JtAd3�/� ����1���F5o���i���!��{�s�O5��y�&�#�� ��@�s�y��:�\T>%tAg���C? ����`؝�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��~��"��� Show the Earth from Space photograph. With 189 member countries, staff from more than 170 countries, and offices in over 130 locations, the World Bank Group is a unique global partnership: five institutions working for sustainable solutions that reduce poverty and build shared prosperity in developing countries. 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. Fresh water may include water in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers, streams, and even underground water called groundwater. You will not receive a reply. 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. ), and delivery (are systems in place to bring water to users?) /GSa 3 0 R The threat to water availability for this area is rated “Medium” (between 20% and 40%) meaning, based on the OECD classification scheme. << It should be noted that, due to lack of available historical data, the northern part of the province of Quebec has not been evaluated. 3, Upper) will potentially have flows inadequate to maintain biodiversity, because by our definition of water shortage there will be at least 1 mo per year in which some rivers in an ecoregion have essentially all water withdrawn for urban use. 3 0 obj 10 0 obj /Pattern << In British-Columbia, the ratio is also low (below 10%). The resulting shift in community structure will have significant impacts on species assemblages and will greatly alter the food web as well as the physical structure of freshwater habitats. Sub-drainage areas with a high threat to water availability (More than 40% of water use) are the 05F (Battle), 05N (Souris), 11A (Missouri), 02F (Eastern Lake Huron), 02G (Northern Lake Erie) and 02H (Lake Ontario and Niagara Peninsula). Freshwater provision to urban residents has three components: water availability (is there enough water nearby? 05B-Bow, 05J-Qu’Appelle and 05M-Assiniboine). Due to extreme climatic conditions and the particular hydraulic regime of the region (e.g., frozen streams) it was, however, decided that the methodology used in the Water Availability Indicator initiative is not applicable for the extreme northern part of the country.
