Phosphorus interception and
Re-Use
�Why Phosphorus? �Planetary Boundaries
P Planetary boundary requires policy focus and management innovation
Global ban on CFC production (reliant on technical innovation)
Reliant on GHG market instruments, ie for renewable energy
Reliant on MEAs; ie Convention on Biodiversity
RM of Rosser Case Study
Case Study:
The Rural Municipality of Rosser and Grant’s Lake
LiDAR for Natural Infrastructure �Systems Design

Shown here is the RM of Rosser (brown), the building inventory picked up by the Microsoft AI Building Database (pink) and the ‘core’ Rosser buildings (orange)��The total building area is 47.9 Ha and the core area is 10.28 Ha

Grant’s Lake
CentrePort
The core building area was semi-arbitrarily selected, to include the area of highest tax-base as well as the main economic hub of the RM. many of the largest buildings in the RM are also in this area��Applying a 1.14 GJ/m2 * 74.79% efficiency figure onto the core area of 10.28 Ha gave an approximate demand of 74,261 GJ per year��

CentrePort:
~75,000 GJ/year

This ditch productivity estimation method originally was done for the RM of Rosser��The area for the RM of Rosser, plus major watersheds running within it amount to about 6,168 hectares��Some of this area, namely the northwest and extreme southeast areas fall outside of the WMR
