  2. Benefits of Improved Soil Moisture Information Depth of dye penetration (cm) Optimal Time Larger Pore Flow Average Soil Water Content (%) Crack Bypass D. Lapen, Research Branch, AAFC 2008 Producers: Improved understanding and prediction of soil moisture would allow producers to: • manage better during period of excess and insufficient moisture; • improve yield predictions • minimize on-farm environmental risk (e.g., when to spread manure)

  3. Benefits of Improved Soil Moisture Information • Federal and Provincial programs: • Improved predictions would reduce disaster payouts • ~ 5.8 billion loss to Canada incurred in the 2001-2002 drought. If planning-monitoring-adaptation programs reduced loss by even <1%, $ 10’s of millions could be saved. • Cover Crop Protection Pgm. (CCPP) costs > $100M; a reduction in affected acreage by 10% would have saved $3.5 Million in 2005 alone • Impact on competitiveness • Money saved by reduced disaster relief costs is money available for options to improve the sector’s competitiveness

  4. Benefits of Improved Soil Moisture Information Early warning of extreme weather events • Flood and runoff warnings • Enhance human safety • Reduce risk of water contamination • Human health warnings • Risk of radon entering residential basements • Poor air quality due to low-level atmospheric mixing • Forestry • Enhanced forest fire risk assessment Water Resources • Water availability • consistent with emerging recommendations for the Deputy Ministers’ Committee on Economic Prosperity, the Environment and Energy from interdepartmental working group to better understand and predict water availability Value of Improved Weather Forecasting

  5. Where did it start? Towards a Federal Earth Observation Strategy for Canada (2006) • Developed by EC, AAFC, NRCan, CSA, DFO, HC, DFAIT as participants in the Canadian Group on Earth Observation (CGEO) • A better understanding of the water cycle is a priority for Canada • Increased economic development and population growth will put increasing demand on Canada’s land and water resources. • Climate change is adding uncertainty as to how droughts, floods and other extreme events will impact the sustainability of our environment, our economic competitiveness and our public health and safety • Our ability to better predict climate variability and improve our forecasting of extreme events will be critical in our ability to maintain competitiveness in all economic sectors. • Soil Moisture was determined to be a key component in improving our understanding of the water cycle

  6. Where did it start? • Identified improved soil moisture monitoring as key priority in understanding the water cycle: • Current monitoring in Canada is ad hoc and uncoordinated between regions and agencies. Need for national consistency. • New opportunities to harness emerging technologies to improve data • Opportunity to work with US to build a continental system • Establish a working group on soil moisture

  7. Soil Moisture Working Group • Established working group on soil moisture under CGEO • Purpose is to work toward a better understanding of Soil moisture in Canada • 2 major outputs from this group • Soil Moisture Monitoring Workshop May 2007 • Develop Way Forward document (May 2008) and work plan

  8. Soil Moisture Monitoring Workshop • Held in Saskatoon, Saskatchewan May, 2007 • Purpose : The main objectives of the workshop was to provide information and input into drafting a path forward to address the needs for soil moisture monitoring , analysis and prediction information in Canadian agricultural landscapes.. • organized under the umbrella of the interdepartmental Canadian Group on Earth Observations (CGEO), in close collaboration with Agriculture and Agri-Food Canada and Environment Canada. • 4 main topic areas • In Situ Monitoring, Remote Sensing, Modelling and Data Assimilation, User Services and Applications • Break out groups for each area

  9. Soil Moisture Monitoring Workshop • Short Term Goals (< 2 years) • In-Situ Monitoring: • Form working group(s) for sensor selection/defining standards, for quality control and calibration, for network design, and for data assimilation • Network design manual of procedures • Write operating procedures • Define data standards • Determine locations for test bed facilities • Ensure sustainability of existing networks (Quebec has funds ending soon) • Plan workshop for quality control of data and assimilation of existing data • Identify partners and user requirements

  10. Soil Moisture Monitoring Workshop • Short Term Goals (< 2years) • Remote Sensing • Generate inventory of existing data • Execute formal partnership agreements • Obtain access to existing L band SAR data (ALOS PALSAR) • Find resources to work with SMOS data, initially for calibration and validation • Form partnerships in SMAP mission • Improve understanding of relationship between point observations and pixel scale observations

  11. Soil Moisture Monitoring Workshop • Short Term Goals (< 2years) • Modeling and Data Assimilation • Execute agreements to access near-real time data on soil moisture and precipitation • Gain access to existing land cover and soil texture data sets • Write model documentation • Improve assimilation of existing remotely-sensed data • Participate in new satellite planning • Research on the inclusion of remote-sensing data in a Canadian LDAS

  12.
