LIRA (Land and Infrastructure Resiliency Assessment)

Extreme climatic events over recent years illustrate that agricultural areas of Canada are vulnerable to climate variability, particularly climate extremes that significantly affect agri-environmental issues such as surface and groundwater contamination and soil degredation. This raises some important questions. Is it possible to 'adapt' the local landscape to mitigate flood-related damage? And might the benefits of doing so outweigh the costs of implementation? LIRA attempts to answer these questions... 
 
The objectives of the LIRA project are to:
  •  Assess the risk to a region's infrastructure systems and the environment, and
  • Develope and rank adaptation options that reduce socio-economic and environmental costs.
Simply put, LIRA provides a proactive approach to minimize future negative impacts caused by extreme precipitation in our watershed.
 
LIRA was developed by Ag Canada in order to create a tool that municipalities can utilize to fascilitate planning and preparation for future flooding scenarios. The first test of the methodology took place in the RM of Corman Park, near Saskatoon, SK in 2008.
The AWSA is one of 3 watershed groups in the province that are currently undertaking LIRA pilot projects. We will be starting activities summer, 2011. See the map below for the study area.
 
STEPS OF THE LIRA PROCESS:
1) Map the landscape - We were out starting this summer, mapping the landscape of the two study areas in terms of land use (e.g. cropland, hay, pasture, etc), water-related infrastructure (e.g. culverts and bridges), and other residence/infrastructure info (e.g. farmyards, barns, corrals, etc).
2) Assign economic value to what was mapped.
3) Model various flood scenarios on the landscape (e.g. 1 in 10 yr flood, 1 in 100 yr flood, etc) and determined the economic impacts.
4) Rerun the flood model, this time with various mitigation options (e.g. wetland restoration, new water infrastructure, different zoning around urban centers, etc) and perform a cost/benefit analysis.
5) Reach informed decisions regarding flood risk management.
